  1. 0:03Every battle for survival has one rule.
  2. 0:08The strongest one does not always win.
  3. 0:13[music]
  4. 0:13The dry season grips the okavango.
  5. 0:17The African savannah grass turns dry
  6. 0:22and the young in this lion kingdom hang
  7. 0:25in the balance.
  8. 0:28Will the herd hold on to what it wants?
  9. 0:33[music]
  10. 0:43[music]
  11. 0:48[music]
  12. 1:01Tell us below whose side you are on
  13. 1:05before the greatest fights of the
  14. 1:07savannah begin.
  15. 1:20The Oak of Angal is a rare inland delta.
  16. 1:28Its water never reaches the sea.
  17. 1:32It spreads out along the edge of the
  18. 1:34Kalahari Desert.
  19. 1:37UNESCO calls it one of the few inland
  20. 1:40deltas still left in its natural state.
  21. 1:48Even when the channel runs almost dry,
  22. 1:52the most patient hunter here stays.
  23. 1:57[music]
  24. 1:59Every year that water comes and goes to
  25. 2:03its own rhythm,
  26. 2:06and the web of life here must learn to
  27. 2:09live by that beat.
  28. 2:14The flood here is not born from rain on
  29. 2:18the delta.
  30. 2:20It starts with storms on the Angolan
  31. 2:23highlands. [music]
  32. 2:25Hundreds of miles off, then takes
  33. 2:28[music] weeks to reach the Kalahari
  34. 2:30basin.
  35. 2:33Right when the Okavango dry season
  36. 2:35[music] bites hardest, that water is
  37. 2:38already on its way.
  38. 2:42>> [music]
  39. 2:43>> In the meantime, every living thing here
  40. 2:47has to get by on whatever the dry season
  41. 2:50leaves.
  42. 2:51If this drought goes on longer, life
  43. 2:55here will fall apart before the water
  44. 2:58returns.
  45. 3:02The fish eagle's call carries for miles
  46. 3:06a sound many still call the voice of
  47. 3:10Africa.
  48. 3:12A distress call about the water louder
  49. 3:16each day.
  50. 3:19Impala live in herds for a simple
  51. 3:23reason.
  52. 3:25The more eyes watching,
  53. 3:28the harder for a hunter to get close.
  54. 3:32They groom one another with scent glands
  55. 3:35under the eyes. How the herd keeps
  56. 3:39knowing who is who in the crowd.
  57. 3:43And when forced to run,
  58. 3:46they can leap almost 3 m high and 10 out
  59. 3:51in one bound.
  60. 3:54enough to escape most strikes at range.
  61. 3:59But once singled out at close range,
  62. 4:03numbers and leaps no longer help.
  63. 4:08From that moment, only raw speed decides
  64. 4:13who lives.
  65. 4:18This is where three cubs get their first
  66. 4:21real lesson.
  67. 4:23a true hunt out in the open.
  68. 4:27For now, all they can do is watch
  69. 4:31and learn.
  70. 4:41Not every lesson is learned by doing.
  71. 4:45Some lessons are too dangerous to
  72. 4:48practice for real.
  73. 4:52>> [music]
  74. 4:59[music]
  75. 5:05[music]
  76. 5:11[music]
  77. 5:16>> Sometimes the biggest reward comes from
  78. 5:19waiting.
  79. 5:21not from striking first.
  80. 5:27[laughter]
  81. 5:28Feeding her cubs is still easy for now,
  82. 5:34but the flood will change every rule of
  83. 5:37this game.
  84. 5:41The mother teaches her cubs this skill
  85. 5:44because one day they must survive alone.
  86. 5:56That is how every parent in the Okavango
  87. 6:00protects its next generation.
  88. 6:04An impalo's horns can kill with one
  89. 6:07wrong strike. And a mother cheetah gets
  90. 6:11no second chance.
  91. 6:15This animal's greatest weapon is not
  92. 6:18strength, but speed. And the way it
  93. 6:22changes direction mid-sprint at full
  94. 6:26power,
  95. 6:30>> an unusually bendy spine,
  96. 6:34a long tail that works like a rudder,
  97. 6:38and claws that never pull all the way
  98. 6:41in.
  99. 6:44More dog than cat.
  100. 6:49Every part of a cheetah's body serves
  101. 6:52one job.
  102. 6:55Get to full speed fast,
  103. 6:58then turn faster still.
  104. 7:03But that speed comes at a price.
  105. 7:06A chase at full power lasts only a few
  106. 7:10dozen seconds before the body overheats
  107. 7:13and has to stop.
  108. 7:17even with prey right in front of it.
  109. 7:26As many as nine in 10 cheetah cubs
  110. 7:29never live to see adulthood in the wild.
  111. 7:34Most [music] lost to lions, hyenas, or
  112. 7:38birds of prey.
  113. 7:40From [music] 6 weeks old, they already
  114. 7:43follow their mother onto the plains.
  115. 7:46But it takes almost [music] a year
  116. 7:48before they join a hunt
  117. 7:51and their mother raises them alone until
  118. 7:5418 months old.
  119. 7:58[music]
  120. 7:59Between hunts, the siblings still play
  121. 8:02rough, drilling the grip on the throat,
  122. 8:06the bite to the [music] neck they will
  123. 8:08need once no one hunts for them.
  124. 8:17At high noon, when the sun burns
  125. 8:20hottest,
  126. 8:22most bigger hunters rest to save
  127. 8:25strength.
  128. 8:27That is when the cheetater chooses to
  129. 8:29hunt to avoid a straight fight with
  130. 8:32rivals too worn out by the heat to move.
  131. 8:37A choice about timing can matter as much
  132. 8:41as speed.
  133. 8:45This mother did what she set out to do
  134. 8:48and passed on [music] a lesson that
  135. 8:50works.
  136. 8:57And now the flood rolls in.
  137. 9:03Some species here only survive because
  138. 9:07the okavango never [music] quite dries
  139. 9:10up.
  140. 9:14The red lequ has unusually wide hooves
  141. 9:19built for moving across muddy ground.
  142. 9:30The Okavand's first flood rolls in,
  143. 9:40carrying water overground, cracked, dry
  144. 9:44for months.
  145. 9:46The flood water carries silt
  146. 9:50and within weeks thick new grass covers
  147. 9:54the ground that was once driest of all.
  148. 10:03Thousands of buffalo break off their
  149. 10:05migration [music] and return to this
  150. 10:08ground where the flood lays out a green
  151. 10:11feast.
  152. 10:17A grown bull buffalo can weigh over 700
  153. 10:21kilos.
  154. 10:23Each carries a bony shield on its
  155. 10:26forehead,
  156. 10:28something no other grazer here has.
  157. 10:35African buffalo rarely move alone.
  158. 10:39A herd can run into the hundreds, and
  159. 10:43that number is the first armor against
  160. 10:46every hunter in the Okavango.
  161. 10:51[music]
  162. 10:54No single leader ever runs a buffalo
  163. 10:59herd.
  164. 11:00Which way the herd moves is decided
  165. 11:04[music] by the grown females.
  166. 11:07Each one stands up, looks one way, as if
  167. 11:12casting a vote with her eyes.
  168. 11:17The herd only turns once enough of those
  169. 11:21eyes agree.
  170. 11:26Another
  171. 11:31buffalo has just gone through a long
  172. 11:33journey with no time to rest after
  173. 11:36birth.
  174. 11:43Since giving birth, she has been more
  175. 11:45worn out than ever.
  176. 11:48But her calf is full of energy, and her
  177. 11:51job is to keep it safe.
  178. 11:59At the same time,
  179. 12:02another jacka on the oak of anger raises
  180. 12:05its young alone,
  181. 12:08holding its floating nest for 21 days.
  182. 12:16This devoted father can guard his whole
  183. 12:19[music] brood alone under his own wings.
  184. 12:26This flood does not just feed the grass.
  185. 12:33Young fish pour into the pools
  186. 12:36and birds follow to feed.
  187. 12:41[music] A brief season of plenty before
  188. 12:44the water pulls back.
  189. 12:50Heat.
  190. 13:14Heat.
  191. 13:23>> [music]
  192. 13:32>> Strike one and you fight the whole herd.
  193. 13:42The mother and her calf are safe this
  194. 13:46time.
  195. 13:49Numbers out here
  196. 13:51are the weaker side's greatest weapon.
  197. 13:59So what decides a fight for survival?
  198. 14:02Numbers and teamwork
  199. 14:05or one animals strength?
  200. 14:10Tell us in the comments.
  201. 14:15Out here, numbers and the instinct to
  202. 14:20protect one's young decide who wins.
  203. 14:27Lions,
  204. 14:29unlike buffalo,
  205. 14:31live within a fixed territory.
  206. 14:35A pride cannot wander too far.
  207. 14:40or stay away too long.
  208. 14:45Because hunger waits for no one and a
  209. 14:48cub fed nothing today
  210. 14:52may not be there tomorrow.
  211. 14:56That is why this young pride gamles on a
  212. 14:59buffalo herd
  213. 15:01rather than leave its ground for easier
  214. 15:04prey elsewhere.
  215. 15:12No map marks territory in the Okavango.
  216. 15:20It is marked by scent
  217. 15:24by roars carrying for miles
  218. 15:28and by [music] the pride showing up day
  219. 15:32after day.
  220. 15:35Stay away too long and you have lost it.
  221. 15:46Hyenas fight lions for this ground,
  222. 15:49[music] too.
  223. 15:51The two compete for prey
  224. 15:54and steal each other's kills. [music]
  225. 15:57So, every hunt in the Okavango has a
  226. 16:00cost.
  227. 16:04staying on guard
  228. 16:07even after winning.
  229. 16:14Few know that hyena clans are led by
  230. 16:17their oldest females.
  231. 16:20A social order as tight as a lion
  232. 16:23prides.
  233. 16:25Just [music] rarely talked about.
  234. 16:32[music] But the water never stays for
  235. 16:35good.
  236. 16:39In a few more weeks,
  237. 16:42this ground [music] turns into the
  238. 16:44greenest grass of the year.
  239. 16:47The richest stretch the Okavango can
  240. 16:50offer a hunter.
  241. 16:57[snorts]
  242. 16:59The flood has pulled back.
  243. 17:07leaving the greenest grass of the year.
  244. 17:14This is the easiest hunting season the
  245. 17:17Okavango can offer.
  246. 17:20A coalition of mother African lions with
  247. 17:23small cubs in tow.
  248. 17:31[music] Zebra stay close behind the
  249. 17:33retreating water line where the first
  250. 17:37new grass comes up.
  251. 17:42The flood's rhythm decides where [music]
  252. 17:44prey gathers and a coalition that knows
  253. 17:48its ground will know where that spot is
  254. 17:52before the zebra herd gets there.
  255. 18:03Zebra are not the only ones waiting.
  256. 18:10Wild beast and tesse come too.
  257. 18:18Each going for a different grass height,
  258. 18:21sharing this field with barely any
  259. 18:24competition.
  260. 18:26[music]
  261. 18:34A full-grown zebra weighs almost as much
  262. 18:37as four lions,
  263. 18:40and one kick from its hind legs can
  264. 18:43break the jaw of a hunter reckless
  265. 18:46enough to close in alone.
  266. 18:49Plenty of food does not mean less
  267. 18:52effort.
  268. 18:59This time these mothers cannot afford to
  269. 19:02fail
  270. 19:06the way that young pride once did.
  271. 19:14Those stripes are not just for hiding.
  272. 19:20Many scientists think the pattern keeps
  273. 19:22flies off the skin.
  274. 19:26A small defense against [music]
  275. 19:27parasites
  276. 19:29before any hunter shows up.
  277. 19:33[music]
  278. 19:37A coalition of lionesses
  279. 19:40is close blood relatives
  280. 19:43raised in the same pride,
  281. 19:47sharing the work of raising young,
  282. 19:51even nursing one another's cubs. if
  283. 19:54needed.
  284. 19:57They stand shouldertosh shoulder
  285. 20:01even against the pride's own male.
  286. 20:05Lionesses are also the fiercest group
  287. 20:09hunters on the savana.
  288. 20:14Hunting as one group brings down bigger
  289. 20:18prey than any single lioness could
  290. 20:21manage alone.
  291. 20:28Cubs born into a coalition like this
  292. 20:33depend on their mothers until 2 years
  293. 20:36old.
  294. 20:42Without the group to protect them, most
  295. 20:45cubs would never reach adulthood.
  296. 20:50The bigger a coalition,
  297. 20:52the more eyes watch cubs against hyenas,
  298. 20:58leopards, or strange male lions.
  299. 21:03That is why no mother lion hunts alone.
  300. 21:08Not if she has any other choice.
  301. 21:16All day the lion cubs chase one another,
  302. 21:20[music] pouncing on anything that moves.
  303. 21:25That play is never just for fun.
  304. 21:29It drills the stalk,
  305. 21:32pounce, and grip a coalition will need
  306. 21:36on its own hunts.
  307. 21:40No successful hunt means no meal for the
  308. 21:44whole group.
  309. 21:46Not even one
  310. 21:49female lions do most of the hunting for
  311. 21:52the pride,
  312. 21:5485 to 90%,
  313. 21:57usually by ambush.
  314. 22:00Working together lets them bring down
  315. 22:02huge prey.
  316. 22:04Animals the size of a buffalo, a rhino,
  317. 22:09or a giraffe.
  318. 22:17Today they have found their target.
  319. 22:21But singling out one animal from the
  320. 22:24herd is never simple.
  321. 22:46>> [laughter]
  322. 22:50>> One zebra is enough to feed this family
  323. 22:53of mothers and cubs for days.
  324. 23:00This becomes a race against the clock.
  325. 23:07The farther the scent of blood travels,
  326. 23:11the more prides show up for a share
  327. 23:18before vultures signal it to the sky.
  328. 23:22From hundreds of meters up,
  329. 23:26one vulture spots another dropping down
  330. 23:30and follows it down.
  331. 23:33In a few minutes, word of a hunt just
  332. 23:37ended
  333. 23:38can spread across the sky.
  334. 23:45This time the mothers have won. But the
  335. 23:49race against being found out never
  336. 23:52really ends.
  337. 23:55Sand only buys one afternoon.
  338. 24:03The vultures will find [music] this meal
  339. 24:06soon enough,
  340. 24:08even once little is left.
  341. 24:12As efficient as these cleaners are, this
  342. 24:16natural warning system keeps growing
  343. 24:19thinner each year.
  344. 24:24Falter populations across Africa have
  345. 24:27fallen by more than half in decades.
  346. 24:32And once falters are gone,
  347. 24:35carcasses linger longer and disease
  348. 24:40spreads farther.
  349. 24:43The new order of the Okavango
  350. 24:46stays the same. A successful hunt today
  351. 24:51promises nothing for tomorrow.
  352. 24:58Three fights, three endings, one hunt
  353. 25:02done perfectly,
  354. 25:05one defeat by numbers,
  355. 25:08and one win bought with neverending
  356. 25:11watchfulness.
  357. 25:14Not one of these three fights was
  358. 25:18decided by raw strength alone.
  359. 25:28The cheetah wins on speed.
  360. 25:32The buffalo wins through numbers.
  361. 25:37The lions win by working together at the
  362. 25:40right moment in the right place
  363. 25:44as the water pulls back.
  364. 25:51Even a single jakana quiet on its nest
  365. 25:55through flood season
  366. 25:57is living by that same rule.
  367. 26:03One rule runs through all three.
  368. 26:07Life in the Okavango is never handed out
  369. 26:13and never easy to hold on to.
  370. 26:20In this kingdom of the African lion, the
  371. 26:23predator does not always win.
  372. 26:27Through one dry season,
  373. 26:30one flood, then another dry season,
  374. 26:35the mothers decide who lives and who
  375. 26:39does not.
  376. 26:41The flood will pull back again.
  377. 26:45The dry season
  378. 26:47will come again.
  379. 26:51That wheel never stops.
  380. 27:00The fires that close the dry season burn
  381. 27:04the old grass,
  382. 27:07clearing the way for new shoots.
  383. 27:11A small destruction
  384. 27:14traded for a fresh start.
  385. 27:19This year's mother cheetah will grow
  386. 27:21old.
  387. 27:23Her cubs will stand on their own when
  388. 27:26another dry season grips the Okavana.
  389. 27:32And somewhere else, another coalition
  390. 27:36at another bend along the water will
  391. 27:39face the same choice.
  392. 27:43Risk it or wait.
  393. 27:49But the rule never changes.
  394. 27:52Survival is fought for and taken,
  395. 27:57not given.
  396. 28:00No winner in the oak of holds the throne
  397. 28:03for good.
  398. 28:05Only the parents willing to step out
  399. 28:08again once the season turns and everyone
  400. 28:13plays again on the same terms.
  401. 28:18So tell us in this lion kingdom
  402. 28:22who really holds the throne,
  403. 28:26the predator or the parents who never
  404. 28:29stop fighting.

  412. 29:02houses an ancient [music] forest even
  413. 29:05older than the Amazon,
  414. 29:09where more than 20 million people live.
  415. 29:14Yet, no one has ever truly tamed it.
  416. 29:20Borneo sits right along the equator and
  417. 29:24is shared among three nations
  418. 29:27with Indonesia holding the southern
  419. 29:30region
  420. 29:32while Malaysia and Brunai split [music]
  421. 29:35the Northern Territory.
  422. 29:39Yet the real boundaries that shape life
  423. 29:42here were never drawn up by any
  424. 29:44government.
  425. 29:47They are carved by flowing waters,
  426. 29:51by dense forest canopies, and by the
  427. 29:54rolling tides of the sea.
  428. 29:58Here, a city awakens right at the feet
  429. 30:02of a sacred mountain.
  430. 30:05[music] An entire village slumbers
  431. 30:08beneath a single roof.
  432. 30:12Young children learn to dive
  433. 30:15before they even walk.
  434. 30:19And swarms of bats stream out of cave
  435. 30:23mouths dense as a plume of dark smoke.
  436. 30:30Towns home to thousands of people rise
  437. 30:34on wooden stilts hovering over river
  438. 30:38currents without a single road touching
  439. 30:42solid ground.
  440. 30:46Every community across this island is
  441. 30:49answering the exact same question in
  442. 30:53their own way.
  443. 30:57Not how to conquer the wild,
  444. 31:00but how to strike a balance with it.
  445. 31:06Deep within one of the oldest remaining
  446. 31:09forests on Earth,
  447. 31:12survival at the end of the day comes
  448. 31:15down to harmony rather than conquest.
  449. 31:21The people here have learned to let
  450. 31:24nature shelter them.
  451. 31:27and walk hand in hand with the natural
  452. 31:31world in mutual [music]
  453. 31:33respect.
  454. 31:37[music]
  455. 31:41That is precisely how people live on
  456. 31:45Borneo,
  457. 31:47an island spanning nearly 300,000
  458. 31:51square miles.
  459. 31:54Kota Kinabalo
  460. 31:56serves as the capital of Sabah in
  461. 31:59Malaysian northern Borneo.
  462. 32:03Home to half a million residents
  463. 32:07and the single largest city across
  464. 32:10[music] the entire island.
  465. 32:14Behind them stands a mountain so high
  466. 32:20it can create weather patterns of its
  467. 32:23own.
  468. 32:26As dawn breaks, the coastal [music]
  469. 32:29fish market is already packed to the
  470. 32:32gills.
  471. 32:35[music]
  472. 32:38Boats ride low in the water, burdened
  473. 32:42with fresh seafood,
  474. 32:45harvested after a night of fishing
  475. 32:48around distant islands.
  476. 32:52Traders of Philippine descent
  477. 32:55display tuna and grouper over beds of
  478. 32:58crushed ice.
  479. 33:01A woman skillfully guts a fish with just
  480. 33:06[music] three swift slices,
  481. 33:10then calls out her price while [music]
  482. 33:13buyers drive a hard bargain for trays of
  483. 33:16shrimp still jumping around.
  484. 33:21The air carries the sharp tang of sea
  485. 33:24salt, the smell of diesel fuel, and the
  486. 33:27rich aroma of grilled meat.
  487. 33:31On Sundays,
  488. 33:33the Tamu Open Market brings the entire
  489. 33:36downtown [music] area to life
  490. 33:40as villagers from the hills bring down
  491. 33:43rice, honey, and handrolled tobacco to
  492. 33:47sell
  493. 33:49while the Joe women display river pearl
  494. 33:52necklaces on woven ratan trays.
  495. 33:57By 8 in the morning, the streets are
  496. 34:01choked up with motorbikes and office
  497. 34:03workers.
  498. 34:07This is a modern metropolis complete
  499. 34:10with shopping malls, traffic signals,
  500. 34:12and a mosque that appears to float over
  501. 34:16the lagoon.
  502. 34:18Yet, the ancient forest never steps
  503. 34:21back.
  504. 34:23along with dozens of other communities.
  505. 34:27Each holds onto its own kitchen corner
  506. 34:31and its own prayers.
  507. 34:34They built this coastal city in the
  508. 34:37[music] span of a single generation.
  509. 34:41While the island quietly holds its
  510. 34:43ground in the background,
  511. 34:48more ancient and vast than anything
  512. 34:51humans could ever set in concrete.
  513. 34:59Heading down toward the western coast,
  514. 35:02another river city drifts along at a
  515. 35:06much slower pace.
  516. 35:09Kuching, the capital of Sowak state,
  517. 35:14stretches along both banks of the Sowak
  518. 35:17River.
  519. 35:22In the local dialect, its name
  520. 35:24translates to cat. And the residents
  521. 35:28here take great delight in this
  522. 35:31coincidence,
  523. 35:34placing cat statues on guard right at
  524. 35:38the traffic roundabouts.
  525. 35:41Yet the true heartbeat of Kuching rests
  526. 35:45out on the water.
  527. 35:48Wooden ferryboats known as tambang have
  528. 35:51been shuttling passengers across the
  529. 35:53river since time in memorial.
  530. 35:58The boatman stands at the helm
  531. 36:01pushing the oars to collect small change
  532. 36:06just as his ancestors did before him.
  533. 36:11On the opposite bank lie ancient [music]
  534. 36:14Kampong villages
  535. 36:17with wooden houses swaying on stilts
  536. 36:21clad in faded layers of green and blue
  537. 36:24paint.
  538. 36:27Malay residents settled here long ago,
  539. 36:31and the call to prayer echoing at first
  540. 36:34light, drifting across the reddish brown
  541. 36:37waters,
  542. 36:39has become the familiar rhythm of every
  543. 36:42morning.
  544. 36:46>> [music]
  545. 36:46>> A woman sweeps her stilt porch,
  546. 36:51then hangs laundry to dry right over the
  547. 36:55tidal waters,
  548. 36:58while a few cats stroll along the wooden
  549. 37:01walkways
  550. 37:03without giving a second thought to the
  551. 37:06river below.
  552. 37:13Strolling through the old market,
  553. 37:17you see the entire island condensed into
  554. 37:22a single street.
  555. 37:29Chinese grocery stores sell traditional
  556. 37:34herbs, rich coffee, and piping hot
  557. 37:38steamed buns.
  558. 37:41While Indian merchants scoop up handfuls
  559. 37:45of spices onto the scales,
  560. 37:49by evening the waterfront bustles with
  561. 37:53families enjoying the cool breeze.
  562. 37:58They grill saté skewers and stir
  563. 38:01steaming pans of sowak laxa
  564. 38:06while elders play chess beneath the
  565. 38:08streetlight glow.
  566. 38:12Across the water, the domed government
  567. 38:15buildings glow in radiant gold light.
  568. 38:19A solitary tambang quietly docks through
  569. 38:23the shimmering reflections,
  570. 38:26its single lantern swaying to the rhythm
  571. 38:30of the waves.
  572. 38:33No single community dominates Kuchin.
  573. 38:37Mallay, Chinese, Eban and Bau
  574. 38:43all share the same riverbank and
  575. 38:45marketplace.
  576. 38:49Here harmony has never meant standing
  577. 38:53apart,
  578. 38:55but living side by side with neighbors
  579. 38:58who worship different gods,
  580. 39:02all while considering this arrangement
  581. 39:05home.
  582. 39:10Stretching along this river, out of
  583. 39:13every 100 acres of forest,
  584. 39:1780 have vanished, making way for endless
  585. 39:21rows of oil palms [music] stretching all
  586. 39:24the way to the horizon.
  587. 39:28The Kinabatangan is Sabar's longest
  588. 39:32river,
  589. 39:34meandering through the eastern plains
  590. 39:37toward the sea.
  591. 39:40The rare surviving patches of forest now
  592. 39:44amount to a paper thin green ribbon
  593. 39:48clinging to both banks.
  594. 39:51And it is within this narrow constricted
  595. 39:54corridor
  596. 39:56that Borneo's entire wild world is
  597. 40:00squeezed together.
  598. 40:03How do you share a river with a creature
  599. 40:07capable of toppling a home?
  600. 40:12The orange [music] sunai, a river
  601. 40:15dwelling people, have farmed along these
  602. 40:18banks for generations.
  603. 40:22Now they awaken [music] in disbelief
  604. 40:26to find pygmy elephants looming right
  605. 40:29inside [music] their plantations.
  606. 40:33These are the smallest elephants on
  607. 40:35Earth,
  608. 40:37standing just a little taller than an
  609. 40:39adult human.
  610. 40:42Shrinking [music] forest area has pushed
  611. 40:44them out into the open to feed on young
  612. 40:48palm shoots.
  613. 40:50And a single herd can sweep clean a
  614. 40:54villagers's entire field in the blink of
  615. 40:57an eye.
  616. 41:00For the river people, boats are the only
  617. 41:03road.
  618. 41:04Children travel to school by motorboat
  619. 41:07at door
  620. 41:09and nurses move from village to village
  621. 41:12using [music] outboard motors.
  622. 41:17There are no bridges here, only muddy
  623. 41:20waters winding between walls of oil
  624. 41:24palms.
  625. 41:25So farmers pull allnighters in the dark,
  626. 41:30banging pots and pans,
  627. 41:33stringing wire and burning old tires to
  628. 41:37shield their crops
  629. 41:39from a creature they were taught to
  630. 41:42respect.
  631. 41:45In the face of this standoff,
  632. 41:48no one comes out a clear winner.
  633. 41:52High above, orangutangs [music]
  634. 41:55move slowly and quietly
  635. 41:58through the remaining treetops.
  636. 42:01Probosus monkeys leap across gaps at
  637. 42:05dusk
  638. 42:06with their unusually large noses
  639. 42:09silhouetted against the sunset.
  640. 42:12While crocodiles keep the muddy shallows
  641. 42:15motionless like drifting logs.
  642. 42:22During a 1-hour journey along this
  643. 42:24winding stretch,
  644. 42:27the wild Borneo remains very much alive.
  645. 42:33All compressed into a narrow ribbon of
  646. 42:36green.
  647. 42:38As night falls, the forest closes in and
  648. 42:43resonates [music]
  649. 42:43with a roaring chorus of insects.
  650. 42:48Somewhere in the dark, an elephant tears
  651. 42:51through a fence and the farmer hurriedly
  652. 42:55grabs his flashlight.
  653. 42:58Men who once felled this forest have now
  654. 43:02turned into tour boat captains.
  655. 43:07A former logger cuts the boat's engine
  656. 43:10to let it drift freely,
  657. 43:13pointing out a mother Oringaong to
  658. 43:16tourists, her presence bringing him
  659. 43:21an income far greater than the timber he
  660. 43:24once harvested.
  661. 43:27Other locals choose to work directly in
  662. 43:30the oil palm plantations,
  663. 43:34harvesting heavy fruit bunches [music]
  664. 43:37under the fierce sun.
  665. 43:40For daily wages, the very palm tree that
  666. 43:44draws invading elephants
  667. 43:47is what pays the bills for their
  668. 43:49children's schooling.
  669. 43:53Here, the compromise that allowed humans
  670. 43:56and ancient forests to coexist [music]
  671. 43:59on one island is beginning to fray.
  672. 44:04And anyone living along the Kabatang
  673. 44:08can watch it unravel season after
  674. 44:12season.
  675. 44:15The forest that shaped their river way
  676. 44:18of life is now measured acre by acre and
  677. 44:23that number continues to shrink.
  678. 44:31On the African plains,
  679. 44:33two powers have faced each other for
  680. 44:36tens of thousands of generations.
  681. 44:40On one side, the lion pride, [music]
  682. 44:44a symbol of culling and coordinated
  683. 44:47strength.
  684. 44:50[music]
  685. 44:54On the other, the Cape Buffalo herd.
  686. 44:59Their rivalry is as aid as the savannah
  687. 45:03itself.
  688. 45:13For a lion pride,
  689. 45:16buffalo are among the most valuable prey
  690. 45:19on the plane.
  691. 45:21But the greater the prize, the higher
  692. 45:24the price.
  693. 45:36Buffalo are also the most dangerous prey
  694. 45:41in all of Africa.
  695. 45:44[music]
  696. 45:49Alone, a lion can almost never
  697. 45:55bring down a full grown buffalo.
  698. 46:04Only together
  699. 46:06does the pride turn separate strength
  700. 46:10into a hunting machine.
  701. 46:25A mature Cape Buffalo herd
  702. 46:30is never small.
  703. 46:36Depending on water and grass,
  704. 46:40numbers swing from 50 to 500 animals.
  705. 46:49[screaming]
  706. 46:52A bull can weigh close to a ton.
  707. 46:59Across his skull, the horns fuse
  708. 47:04into a single unbroken shield of bone.
  709. 47:11[screaming]
  710. 47:16When the herd stops to rest, an
  711. 47:19invisible order takes shape.
  712. 47:24The herd becomes a living fortress.
  713. 47:31As long as the wall of horns holds,
  714. 47:36almost no hunter dares to charge in.
  715. 47:44But even a living fortress needs someone
  716. 47:48to lead it.
  717. 47:51At the head of a herd 400 strong
  718. 47:57is a small group of old cows.
  719. 48:05Their experience holds season after
  720. 48:08season
  721. 48:12of surviving inside the ring of a lion
  722. 48:16pride.
  723. 48:25For a lead cow, grazing while watching
  724. 48:29for danger
  725. 48:32has become instinct.
  726. 48:37The herd stays in contact
  727. 48:42through a language of its own.
  728. 48:54As long as that sound stays steady,
  729. 48:59the whole mass grazes in peace.
  730. 49:05When it suddenly falls away, every
  731. 49:07animal knows something is wrong.
  732. 49:13Buffalo are specialist grazers.
  733. 49:18A living mower running almost all day
  734. 49:22without a break.
  735. 49:28That way of feeding ties them to the
  736. 49:31grass
  737. 49:34eat a great deal [music]
  738. 49:38and never stand in one place for long.
  739. 49:48Even breeding runs on a code of its own.
  740. 49:57He reads which cow is coming into
  741. 50:00season.
  742. 50:02Under the dust and the steady sound of
  743. 50:05grazing,
  744. 50:08a whole social order keeps working in
  745. 50:12silence.
  746. 50:15On the backs of all that muscle,
  747. 50:19there are always small guests.
  748. 50:23But these birds take more from their
  749. 50:26host than a single meal.
  750. 50:31And the buffalo sinks into a strange
  751. 50:34distant calm
  752. 50:37as if he has no idea anyone is living on
  753. 50:41his back.
  754. 50:49That buffalo is almost untouchable.
  755. 50:54Inside the herd,
  756. 50:57a few beats apart from it,
  757. 51:01he becomes the most vulnerable target on
  758. 51:04the grassland.
  759. 51:07And that is exactly
  760. 51:11what the pride has been waiting for.
  761. 51:16Heat. Heat.
  762. 51:56The decisive blow is not in the legs
  763. 51:59being locked down.
  764. 52:03It is at the throat.
  765. 52:07The grip seals off any call for help,
  766. 52:16but the sound of the struggle had
  767. 52:18already carried across the grass.
  768. 52:23The balance turns in a matter of
  769. 52:26seconds.
  770. 52:28The first round closes with the wind
  771. 52:30going to numbers.
  772. 52:45For most of the year,
  773. 52:49this herd has to push back attacks from
  774. 52:52the resident lion pride
  775. 52:56[groaning]
  776. 52:57day after day.
  777. 53:03The pride will often just stand and
  778. 53:06wait.
  779. 53:10The smallest movement
  780. 53:13is enough to signal that the hunt has
  781. 53:16begun.
  782. 53:20The pride tends to close in from every
  783. 53:23side at once,
  784. 53:27and the herd does not simply stand and
  785. 53:30take it.
  786. 53:33The bulls charge straight out to meet
  787. 53:36them.
  788. 53:39In that chaos,
  789. 53:42the hunters sometimes find their
  790. 53:45opening.
  791. 53:52And the first to pay
  792. 53:57are usually the young ones who have not
  793. 54:00learned the tactics.
  794. 54:05Hunter and hunted
  795. 54:09share exactly the same ground.
  796. 54:14That is the price the herd pays for
  797. 54:18water and sweet grass.
  798. 54:23Danger and death
  799. 54:27draw the daily rhythm of this herd.
  800. 54:33And the dry season ahead
  801. 54:37is about to make everything harsher.
  802. 54:55The dry season pulls every species
  803. 55:00toward the same few points of water.
  804. 55:08All of them pressed together along the
  805. 55:10mud.
  806. 55:15But living beside a water hole
  807. 55:19is a trade, too.
  808. 55:23After only a few days, the grass around
  809. 55:27the edge is cropped bare.
  810. 55:34For the lead cows,
  811. 55:37that becomes a hard calculation.
  812. 55:40The noring thirst is finally answered
  813. 55:46here, beyond the reach of the lion
  814. 55:49pride.
  815. 55:52The cows visibly let go.
  816. 55:57They know the hard days are very close.
  817. 56:02So they take every easy moment that is
  818. 56:05left.
  819. 56:08A rare pause
  820. 56:10between two brutal seasons.
  821. 56:14But the peace of this oasis
  822. 56:19has never lasted long.
  823. 56:25But when the last water holes shrivel
  824. 56:27into mud,
  825. 56:29the whole network of survival
  826. 56:33is pulled tight.
  827. 56:39And when the map runs empty,
  828. 56:43the hunters go hungry too.
  829. 56:49Only a stagnant mudpool,
  830. 56:53thick and rank,
  831. 56:55[screaming]
  832. 56:56that mud has its uses, too.
  833. 57:01It also works as natural sun protection.
  834. 57:14One cow steps in too deep.
  835. 57:18The soft mud closes hard around her
  836. 57:22legs.
  837. 57:24Any animal that went in to help
  838. 57:28would be caught in exactly the same way.
  839. 57:35and the herd has to move on.
  840. 57:40This is the harsh underside of
  841. 57:42collective [music] strength itself.
  842. 57:50There are lines even a group cannot
  843. 57:52cross,
  844. 57:54not without dragging itself down too.
  845. 58:00Sometimes
  846. 58:02for the many to live, one has to be left
  847. 58:06behind.
  848. 58:11Survival on the savannah
  849. 58:14[music] has never been a simple
  850. 58:15equation.
  851. 58:2140 kilometers away
  852. 58:24on the old grassland,
  853. 58:26the pride gets no rest at all.
  854. 58:31The migration of the cows has taken
  855. 58:34their meals with it.
  856. 58:37Now they have to scrape together
  857. 58:40whatever they can reach.
  858. 58:47Hunger forces the pride to lower its
  859. 58:50standards.
  860. 58:56There are no thousand kilo buffalo
  861. 59:00within reach.
  862. 59:02They have to turn to smaller targets,
  863. 59:07lower risk,
  864. 59:10a far poorer prize.
  865. 59:14And the outcome
  866. 59:17is never certain.
  867. 59:38A lion can go hungry
  868. 59:41for days between successful hunts.
  869. 59:48For every 10 attempts,
  870. 59:51seven times the ruler of the plains
  871. 59:56comes back with nothing.
  872. 1:00:00A hunter spends most of its life inside
  873. 1:00:04failure.
  874. 1:00:09And even the rare successful huntes
  875. 1:00:15another face of hunger.
  876. 1:00:21Imperfect step until the last second
  877. 1:00:26until the food has to be divided.
  878. 1:00:31A warthog is barely one portion.
  879. 1:00:36And the pride male claims first right.
  880. 1:00:41[screaming]
  881. 1:00:44The teamwork dissolves
  882. 1:00:47the moment there is not enough to share.
  883. 1:00:53The rest have to stand and wait.
  884. 1:01:01By the time their turn comes,
  885. 1:01:04only a few streaks of dried blood on the
  886. 1:01:07grass are left to lick.
  887. 1:01:11It is a miscalculation.
  888. 1:01:13He is swatted away.
  889. 1:01:16In hunger,
  890. 1:01:19even blood ties fall behind rank.
  891. 1:01:25Overhead,
  892. 1:01:27the vultures are always waiting.
  893. 1:01:32On the savannah,
  894. 1:01:34no hunger belongs to one animal alone.
  895. 1:01:39But not every prey animal has a fortress
  896. 1:01:42to fall back on.
  897. 1:01:46The savannah holds another lesson
  898. 1:01:51about those who have to fight completely
  899. 1:01:55alone.
  900. 1:01:57They carry exactly one weapon
  901. 1:02:03and one split second to decide how to
  902. 1:02:07use it.
  903. 1:02:12The story now moves to more open country
  904. 1:02:18where speed is the ultimate rule.
  905. 1:02:27Because a cheetah is the living form of
  906. 1:02:30a brutal tradeoff.
  907. 1:02:33To reach unmatched steed,
  908. 1:02:37the body has been stripped down to the
  909. 1:02:40edge of fragility.
  910. 1:02:45A light skeleton, slender muscle,
  911. 1:02:50jaws and claws far weaker than any other
  912. 1:02:53big cat.
  913. 1:02:56A minor injury for a cheetater can be a
  914. 1:02:59death sentence.
  915. 1:03:04The cost of speed is written into every
  916. 1:03:08part of the body.
  917. 1:03:10A cheetah accelerates faster than a
  918. 1:03:13sports car.
  919. 1:03:16hitting top [music] speed within a few
  920. 1:03:19strides.
  921. 1:03:22But that burst burns a terrible amount
  922. 1:03:25of energy.
  923. 1:03:28Within a few dozen seconds,
  924. 1:03:31that body has already reached a
  925. 1:03:34dangerous threshold.
  926. 1:03:37That is why this species usually chooses
  927. 1:03:39small, lightly armed prey.
  928. 1:03:45Like the shorthorned Thompson's gazelle,
  929. 1:03:53a longhorned Grants is usually avoided,
  930. 1:03:59while a safer option still exists.
  931. 1:04:05Grants gazelle are masters of survival
  932. 1:04:08in dry country.
  933. 1:04:11They can go for days almost without
  934. 1:04:14drinking,
  935. 1:04:17pulling water straight out of the grass.
  936. 1:04:22That ability carries them out onto the
  937. 1:04:25most open plains of all
  938. 1:04:29where there is nowhere to hide, only
  939. 1:04:31speed and a pair of horns to lean on.
  940. 1:04:38Grants gazelle tolerate heat, but many
  941. 1:04:42other species have to avoid.
  942. 1:04:47Their bodies draw water directly from
  943. 1:04:49the grass they eat.
  944. 1:04:53And they can let body temperature run
  945. 1:04:55higher than normal
  946. 1:04:57rather than lose water through sweat.
  947. 1:05:01That is how
  948. 1:05:03they hold ground in the driest country.
  949. 1:05:10where hunters are thinner on the ground,
  950. 1:05:15but also where there is not one tree to
  951. 1:05:17hide behind,
  952. 1:05:20far bigger than her usual prey.
  953. 1:05:24The horns of a male grants
  954. 1:05:27have long been known as a serious
  955. 1:05:30opponent.
  956. 1:05:37Out on the open plains,
  957. 1:05:40most cheetah cubs
  958. 1:05:43never live to adulthood.
  959. 1:05:46Their mother has to hunt enough
  960. 1:05:49and hunt constantly
  961. 1:05:52just to keep the family alive.
  962. 1:06:06>> [music]
  963. 1:06:24>> The gazelle wins,
  964. 1:06:27at least
  965. 1:06:29in this moment.
  966. 1:06:31But on the other side,
  967. 1:06:34an internal injury
  968. 1:06:38strips away the one thing that matters
  969. 1:06:40most to an animal built on speed,
  970. 1:06:46the ability to accelerate.
  971. 1:06:55And her cubs depend on her completely
  972. 1:06:59through their first year. Her
  973. 1:07:06wound becomes a shadow falling over an
  974. 1:07:09entire generation.
  975. 1:07:13One counter strike from the prey.
  976. 1:07:17Paid for with the whole future
  977. 1:07:23of a family on the other side of the
  978. 1:07:26line.
  979. 1:07:33So, in the clash you have just seen,
  980. 1:07:39who do you think actually won?
  981. 1:07:46Leave your answer in the comments
  982. 1:07:50before we move to a new battle
  983. 1:07:56on the far side of the savannah.
  984. 1:08:01The lion pride
  985. 1:08:05after a run of failures
  986. 1:08:09is working toward a completely different
  987. 1:08:11move.
  988. 1:08:19The pride stops and watches.
  989. 1:08:23Day after day, they read the herd like a
  990. 1:08:26map.
  991. 1:08:30looking for the single crack in the
  992. 1:08:32wall.
  993. 1:08:35And then they find it.
  994. 1:08:40She is still inside the herd,
  995. 1:08:44but she can no longer hold the herd's
  996. 1:08:46pace.
  997. 1:08:50The tactics change direction at once.
  998. 1:08:56At first, the herd does not abandon her
  999. 1:08:59outright.
  1000. 1:09:02One bull turns back and stays beside the
  1001. 1:09:06injured cow
  1002. 1:09:10as if lending her a little courage.
  1003. 1:09:17But she cannot walk any faster. And with
  1004. 1:09:20every passing hour, the gap between her
  1005. 1:09:23and herd stretches.
  1006. 1:09:27until the main herd is too far away to
  1007. 1:09:30come back for her.
  1008. 1:09:33Now there is only her
  1009. 1:09:38and the shapes that are waiting.
  1010. 1:09:54The pride is in no hurry.
  1011. 1:09:58They let time and pain finish the work
  1012. 1:10:02that muscle could not.
  1013. 1:10:06Only when she is forced to stop and rest
  1014. 1:10:11do they close the distance
  1015. 1:10:14a little further.
  1016. 1:10:19Hours go by
  1017. 1:10:22in that merciless rhythm.
  1018. 1:10:28It strips the prey of strength.
  1019. 1:10:33Piece by piece and of time.
  1020. 1:10:36The most dangerous weapon the buffalo
  1021. 1:10:39has
  1022. 1:10:40is still intact.
  1023. 1:10:43The holes.
  1024. 1:10:48But horns are only frightening while
  1025. 1:10:51there is still strength behind them to
  1026. 1:10:54swing.
  1027. 1:10:59And that strength is draining away by
  1028. 1:11:02the minute.
  1029. 1:11:04The pride has finally found the one
  1030. 1:11:07thing that can undo a wall of
  1031. 1:11:12That thing is time. Heat.
  1032. 1:11:27Heat.
  1033. 1:11:45And it is over.
  1034. 1:11:49This is the first successful hunt the
  1035. 1:11:51pride has made in the entire season.
  1036. 1:11:57But what matters is how it happened.
  1037. 1:12:03This victory came from patience.
  1038. 1:12:09The strongest is the one who knows how
  1039. 1:12:12to wait
  1040. 1:12:14for the right moment to strike.
  1041. 1:12:20The ruler of the plains has won at last.
  1042. 1:12:27But only by letting go of the very
  1043. 1:12:30strength
  1044. 1:12:33that made its name.
  1045. 1:12:37And that is also the answer to the
  1046. 1:12:40question opened in the first few
  1047. 1:12:43seconds.
  1048. 1:12:50An old ball
  1049. 1:12:54moves away from the herd.
  1050. 1:12:57A kind of bull who has always played the
  1051. 1:13:00unofficial guard for the group.
  1052. 1:13:0511 shapes recognize a rare opportunity.
  1053. 1:13:11They are not fast enough to run a
  1054. 1:13:13buffalo down,
  1055. 1:13:16but together they can overwhelm him with
  1056. 1:13:19numbers.
  1057. 1:13:22And more importantly,
  1058. 1:13:25they have to seal off his call before he
  1059. 1:13:28can bring the herd.
  1060. 1:13:33The ambush lands before the prey can
  1061. 1:13:35react.
  1062. 1:13:39One holds the call shut.
  1063. 1:13:43The other eight work at draining his
  1064. 1:13:46strength.
  1065. 1:13:49A lion the weight of a refrigerator
  1066. 1:13:54hangs its full mass on his neck.
  1067. 1:14:03The pride is working to take that huge
  1068. 1:14:06body apart piece by piece.
  1069. 1:14:13And at that exact moment, something
  1070. 1:14:16breaks.
  1071. 1:14:20The bull is left alone.
  1072. 1:14:25He goes down
  1073. 1:14:29on his back
  1074. 1:14:31in the weakest position of his life.
  1075. 1:14:35For most prey, this is the end.
  1076. 1:14:41But the herd has not truly left.
  1077. 1:14:46The oldest lead cow
  1078. 1:14:50[music] takes the point of the
  1079. 1:14:52counterattack.
  1080. 1:14:57The whole mass drives in and knocks the
  1081. 1:15:01pride off the prey.
  1082. 1:15:06Only when they are facing horns ready to
  1083. 1:15:09run them through, do the lions let go.
  1084. 1:15:15This counterattack is decisive.
  1085. 1:15:20This time, not one lion can hold ground.
  1086. 1:15:27The old bull is pulled back from the
  1087. 1:15:30line of death.
  1088. 1:15:33[music]
  1089. 1:15:34Back into the ranks of his own.
  1090. 1:15:40This victory does not belong to a pair
  1091. 1:15:42of horns.
  1092. 1:15:50It belongs to a group that leaves nobody
  1093. 1:15:53behind.
  1094. 1:15:58On the savannah, unity is the real
  1095. 1:16:02weapon
  1096. 1:16:11on the savannah.
  1097. 1:16:13Survival has never been the privilege of
  1098. 1:16:16the strongest alone.
  1099. 1:16:20It belongs to those who know how to
  1100. 1:16:22fight back
  1101. 1:16:24in the right way
  1102. 1:16:27and at the right moment.
  1103. 1:16:31The sun drops behind the horizon.
  1104. 1:16:35The savannah returns to its ancient
  1105. 1:16:38stillness
  1106. 1:16:40as if no battle had happened at all.
  1107. 1:16:44But tomorrow new encounters will begin
  1108. 1:16:47again.
  1109. 1:16:50Because in this place,
  1110. 1:16:54no power holds its position forever.
  1111. 1:16:59Today's hunter may be tomorrow badly
  1112. 1:17:02wounded.
  1113. 1:17:05Today's prey
  1114. 1:17:08may turn out to be the last one
  1115. 1:17:11standing.
  1116. 1:17:14Only one thing never changes.
  1117. 1:17:19The endless turning between the weapon
  1118. 1:17:21and the will to resist,
  1119. 1:17:25between strength and intelligence.
  1120. 1:17:30And now one last question for you.
  1121. 1:17:35In the three clashes you have just
  1122. 1:17:37watched,
  1123. 1:17:40who was the real winner?
  1124. 1:17:44Leave your answer in the comments
  1125. 1:17:49and stay with us for the next stories
  1126. 1:17:53from the wild heart of the savannah.
  1127. 1:18:02Some countries introduce themselves with
  1128. 1:18:04a glittering skyline, dreamy beaches, or
  1129. 1:18:08postcard mountains.
  1130. 1:18:10Chad introduces itself to the world with
  1131. 1:18:13vast distance and blistering heat that
  1132. 1:18:18lands before the sun even clears the
  1133. 1:18:20horizon.
  1134. 1:18:22And with a silence so immense it feels
  1135. 1:18:26like a kind of weather all its own.
  1136. 1:18:30People call it by a nickname the dead
  1137. 1:18:33heart of Africa.
  1138. 1:18:35Not out of cruelty but because it sits
  1139. 1:18:38at the very center of the continent.
  1140. 1:18:42Sealed in on every side by other nations
  1141. 1:18:46and a thousand miles from the [music]
  1142. 1:18:48nearest ocean. no matter which direction
  1143. 1:18:52you travel.
  1144. 1:18:54And yet nothing about how Chadians live
  1145. 1:18:57here feels dead at all.
  1146. 1:19:01Everything here feels stretched, taught,
  1147. 1:19:05tested,
  1148. 1:19:07and carried with a quiet pride outsiders
  1149. 1:19:11rarely see. Somewhere between the Sahara
  1150. 1:19:15to the north and Green River country to
  1151. 1:19:18the south, nearly 20 million people wake
  1152. 1:19:23up every morning to build an ordinary
  1153. 1:19:26day
  1154. 1:19:28out of one of the harshest landscapes
  1155. 1:19:30[music] on Earth. This footage will show
  1156. 1:19:34you what that life actually looks like.
  1157. 1:19:38Tea poured in the shade at 4 in the
  1158. 1:19:42afternoon.
  1159. 1:19:43Millet pounded by hand before dawn. A
  1160. 1:19:48village that still honors its elders
  1161. 1:19:51the way a compass needle points north.

  1164. 1:20:01don't forget to comment and tell us
  1165. 1:20:04where you're watching from.
  1166. 1:20:18The dry season
  1167. 1:20:22kills no one at once.
  1168. 1:20:30It only takes a little at a time.
  1169. 1:20:35[music]
  1170. 1:20:39And territory once measured in
  1171. 1:20:42footprints
  1172. 1:20:45starts to be measured in hunger.
  1173. 1:20:52Lions widen their range by almost 23
  1174. 1:20:57compared with the wet season.
  1175. 1:21:07Which means paths that never used to
  1176. 1:21:10cross
  1177. 1:21:12now cross every day.
  1178. 1:21:22In this kingdom,
  1179. 1:21:25the throne belongs to a male already
  1180. 1:21:29past his prime.
  1181. 1:21:32>> [music]
  1182. 1:21:35>> He holds the territory. He holds the
  1183. 1:21:38females. And he holds a litter of cubs
  1184. 1:21:43only a few weeks old.
  1185. 1:21:50He also holds what every king holds.
  1186. 1:21:56And no king wants to name.
  1187. 1:21:59A list of those waiting for him to slip.
  1188. 1:22:13A lioness hunting alone.
  1189. 1:22:18succeeds only about one time in six.
  1190. 1:22:26Hunting as a group, that rate nearly
  1191. 1:22:29doubles.
  1192. 1:22:34Today, the wind favors the prey.
  1193. 1:22:39Her scent arrives one beat ahead of her.
  1194. 1:22:47And one beat is enough.
  1195. 1:23:06Heat. Heat.
  1196. 1:23:38>> [laughter]
  1197. 1:23:42>> A failed hunt costs more than a meal.
  1198. 1:23:48It costs time.
  1199. 1:23:51Minutes when the cubs stay behind in the
  1200. 1:23:55thicket
  1201. 1:23:56with exactly one guard.
  1202. 1:24:01But a king used to giving orders
  1203. 1:24:06is very bad at sitting still.
  1204. 1:24:13And while the hunt out there is still
  1205. 1:24:16unfinished,
  1206. 1:24:18a large shape has moved in without a
  1207. 1:24:22sound.
  1208. 1:24:27The mother comes back empty-handed.
  1209. 1:24:32He is the king's brother,
  1210. 1:24:36the cub's own uncle.
  1211. 1:24:40In this world, blood is not a shield
  1212. 1:24:45for an outside male to carry his own
  1213. 1:24:48bloodline forward.
  1214. 1:24:53He has to erase the bloodline already
  1215. 1:24:56there.
  1216. 1:24:57When a new coalition of males takes over
  1217. 1:25:00a pride,
  1218. 1:25:02the cubs of the old pride
  1219. 1:25:05almost never survive.
  1220. 1:25:10This is the leading cause of death
  1221. 1:25:13for lions in their first year of life.
  1222. 1:25:49King arrives last.
  1223. 1:25:53All three without a single wound.
  1224. 1:25:59The throne came close to falling today
  1225. 1:26:04because the one holding it stepped away
  1226. 1:26:09and the male who just backed off.
  1227. 1:26:14Has he really given up?
  1228. 1:26:17And the threat from outside is only half
  1229. 1:26:21the story.
  1230. 1:26:28A young male comes with an expiry date.
  1231. 1:26:39At a certain age, they are pushed out of
  1232. 1:26:43the pride.
  1233. 1:26:46That is the law.
  1234. 1:26:50The law exists for a very practical
  1235. 1:26:53reason.
  1236. 1:26:56Keeping them means raising your own
  1237. 1:26:59rival.
  1238. 1:27:10The eldest son in this pride
  1239. 1:27:14should have left long ago.
  1240. 1:27:18The king let him stay.
  1241. 1:27:27The kingdom is shrinking.
  1242. 1:27:31The prey is leaving.
  1243. 1:27:34And two more grown jaws
  1244. 1:27:37are two more shields.
  1245. 1:27:47But mercy has an inconvenient habit.
  1246. 1:27:53The one who is spared rarely remembers
  1247. 1:27:56the favor.
  1248. 1:28:04Every crack in a lion pride
  1249. 1:28:10begins in the same place, a table.
  1250. 1:28:17The feeding order in a lion pride is
  1251. 1:28:20fixed.
  1252. 1:28:23The dominant male first, then the
  1253. 1:28:26lioness's,
  1254. 1:28:31the cubs and the young ones last.
  1255. 1:28:38A full grown male can take up to 45 kg
  1256. 1:28:42of meat in one sitting
  1257. 1:28:46before the rest is passed down.
  1258. 1:28:51Today
  1259. 1:28:54there is a disrespect coming from the
  1260. 1:28:56grown sons.
  1261. 1:29:01The result is that the prey escapes
  1262. 1:29:07but the mother corrects it.
  1263. 1:29:11The punishment comes on the spot
  1264. 1:29:16and in front of everyone.
  1265. 1:29:21The eldest son does not eat.
  1266. 1:29:26There is a lesser known truth within a
  1267. 1:29:29lion pride.
  1268. 1:29:32Those who feast first
  1269. 1:29:36and those who hunt
  1270. 1:29:38play two distinct roles.
  1271. 1:29:43The lionesses are certainly not getting
  1272. 1:29:46a free ride.
  1273. 1:29:51The lionesses
  1274. 1:29:54operate under a clear division of labor.
  1275. 1:29:59So stepping out of line at the dinner
  1276. 1:30:01table
  1277. 1:30:04is the entire pride's business,
  1278. 1:30:09not just a single individuals.
  1279. 1:30:14While the lion throne cracks from the
  1280. 1:30:17inside.
  1281. 1:30:19In another kingdom on the same land,
  1282. 1:30:23power is being tested too.
  1283. 1:30:31[music]
  1284. 1:30:41On the other side of the land,
  1285. 1:30:45a pack of African wild dogs
  1286. 1:30:50just found themselves out in the cold.
  1287. 1:30:55Giants in search of water passed right
  1288. 1:30:59through the area.
  1289. 1:31:03The pups made it out in the nick of
  1290. 1:31:05time.
  1291. 1:31:09The shelter wasn't so lucky.
  1292. 1:31:15The pups were supposed to stay in their
  1293. 1:31:17den for a few more weeks.
  1294. 1:31:21From that day on, the entire pack
  1295. 1:31:26was constantly on the move.
  1296. 1:31:49They hunt in a way all their own.
  1297. 1:31:53A single hunter rarely secures a meal
  1298. 1:31:57alone.
  1299. 1:32:02>> [laughter]
  1300. 1:32:23[laughter]
  1301. 1:32:40>> For them,
  1302. 1:32:42speed
  1303. 1:32:44takes center stage over tidy perfection.
  1304. 1:32:54The African wild dog
  1305. 1:32:58is one of the rarest carnivores in
  1306. 1:33:00Africa.
  1307. 1:33:04Their strength lies in formation
  1308. 1:33:10and in one individual who leads the way.
  1309. 1:33:16In this pack,
  1310. 1:33:18the one who leads is a female.
  1311. 1:33:23Her power rests on trust.
  1312. 1:33:30She leads the pack
  1313. 1:33:34toward a water hole. She remembers.
  1314. 1:33:39Memory is a pathfinder's greatest asset.
  1315. 1:33:46It is also the first thing the dry
  1316. 1:33:48season destroys.
  1317. 1:33:52That water hole has run dry.
  1318. 1:33:57An adult spotted hyena
  1319. 1:34:00weighs almost twice an African wild dog.
  1320. 1:34:04[laughter]
  1321. 1:34:06In a oneon-one fight,
  1322. 1:34:10[laughter]
  1323. 1:34:12the math is finished before it begins.
  1324. 1:34:22[laughter] But wild dogs fight the way a
  1325. 1:34:25pack fights.
  1326. 1:34:27They do not need to win.
  1327. 1:34:33They need to make winning too expensive.
  1328. 1:34:48[laughter]
  1329. 1:34:52In the end,
  1330. 1:34:55the stronger animal walks away.
  1331. 1:34:59By every ordinary measure, this is a
  1332. 1:35:03victory.
  1333. 1:35:07But a pack keeps score differently.
  1334. 1:35:12What the pack remembers is the dry water
  1335. 1:35:15hole
  1336. 1:35:19and the ambush their pathfinder walked
  1337. 1:35:21them straight into.
  1338. 1:35:26She still has the affection of the pups.
  1339. 1:35:31She has lost the respect of the pack.
  1340. 1:35:35Here
  1341. 1:35:37authority is not lost by losing a fight.
  1342. 1:35:43It is lost by leaving the pack thirsty.
  1343. 1:35:47[music]
  1344. 1:35:49Do you think a leader who loses trust
  1345. 1:35:53like that
  1346. 1:35:56can ever win it back?
  1347. 1:36:00Comment below and stay to the end of the
  1348. 1:36:03story to find out.
  1349. 1:36:16The scouting party that just pulled back
  1350. 1:36:20is part of a much bigger picture.
  1351. 1:36:26Spotted hiennas live in a structure far
  1352. 1:36:28closer to a military force than a
  1353. 1:36:31family.
  1354. 1:36:36Their den operates much like a boot
  1355. 1:36:38camp.
  1356. 1:36:43The young ones compete with each other
  1357. 1:36:46from day one.
  1358. 1:36:51At the bottom of the totem pole, every
  1359. 1:36:53meal is a clash.
  1360. 1:36:58For the lowest ranking member to grab a
  1361. 1:37:00bite,
  1362. 1:37:04they must accept a few harsh nips.
  1363. 1:37:20>> [laughter]
  1364. 1:37:26>> Flying solo keeps things simple,
  1365. 1:37:29[laughter]
  1366. 1:37:32but the stomach remains empty.
  1367. 1:37:36So it learns to live off another's
  1368. 1:37:39[laughter] share.
  1369. 1:37:42And in this kingdom,
  1370. 1:37:45[laughter] even the thieves get robbed.
  1371. 1:38:00[laughter]
  1372. 1:38:21Jackals are faster, greater in numbers,
  1373. 1:38:26and only need a small piece of the pie.
  1374. 1:38:43>> [music]
  1375. 1:38:46>> At night,
  1376. 1:38:49the pack makes another round.
  1377. 1:38:56They read the land to find the
  1378. 1:38:59vulnerable,
  1379. 1:39:01the weak.
  1380. 1:39:04When the water recedes completely,
  1381. 1:39:09the entire kingdom gathers at a single
  1382. 1:39:12spot.
  1383. 1:39:17The last water hole becomes a sanctuary
  1384. 1:39:21for all species.
  1385. 1:39:28And it also turns into the greatest trap
  1386. 1:39:31in the area.
  1387. 1:39:36Hunters here no longer need to chase
  1388. 1:39:39after prey.
  1389. 1:39:43They only need to pick the right spot.
  1390. 1:39:48The prey know this all too well.
  1391. 1:39:52But thirst gives no one the luxury of
  1392. 1:39:56waiting another day.
  1393. 1:39:59[laughter]
  1394. 1:39:59So whoever controls the water hall
  1395. 1:40:05during that dry season
  1396. 1:40:09holds all the cards in the entire
  1397. 1:40:12kingdom.
  1398. 1:40:20The three sons know exactly where they
  1399. 1:40:23stand in their father's eyes.
  1400. 1:40:30So they stop trying to win him over.
  1401. 1:40:36They turn to winning over the females.
  1402. 1:40:42In a lion pride,
  1403. 1:40:45the lionesses are the part that does not
  1404. 1:40:48change.
  1405. 1:40:51Males come and go.
  1406. 1:40:56The females stay.
  1407. 1:41:01Whoever has the females behind him has
  1408. 1:41:05the pride.
  1409. 1:41:10The experienced females weigh two
  1410. 1:41:13things.
  1411. 1:41:16A mother's bond with sons who have grown
  1412. 1:41:22and duty to the king who holds the land.
  1413. 1:41:28The king has seen this before.
  1414. 1:41:33He saw it from the other side.
  1415. 1:41:38on the day he took this kingdom himself.
  1416. 1:41:44He knows exactly how it ends.
  1417. 1:41:51Some lines are crossed only once.
  1418. 1:41:56There will be no more warnings.
  1419. 1:42:02The land has been his for a long time.
  1420. 1:42:09What is coming is a test.
  1421. 1:42:14The eldest son wants to know one thing.
  1422. 1:42:21The authority that has pressed down on
  1423. 1:42:24him all these months.
  1424. 1:42:30How real is it still?
  1425. 1:42:35The answer comes almost at once.
  1426. 1:42:42The king is still heavier,
  1427. 1:42:47still more scarred,
  1428. 1:42:52still knows exactly where to put his
  1429. 1:42:55weight.
  1430. 1:42:59That raw strength is enough to remind
  1431. 1:43:03the females which side they stand on.
  1432. 1:43:07[screaming]
  1433. 1:43:13But this time
  1434. 1:43:17the one facing him
  1435. 1:43:21is his own son.
  1436. 1:43:34myself.
  1437. 1:43:45I don't
  1438. 1:44:17A lucky one at the right moment,
  1439. 1:44:22but it lands.
  1440. 1:44:24The wound is small.
  1441. 1:44:29The consequence is not.
  1442. 1:44:32If the king can be hurt,
  1443. 1:44:36the king can be overthrown.
  1444. 1:44:42The coup fails.
  1445. 1:44:46The king strikes back
  1446. 1:44:49and he strikes back hard.
  1447. 1:44:54Retreating in pieces, the eldest son
  1448. 1:44:58understands
  1449. 1:45:01that if his father wanted to end this,
  1450. 1:45:04he easily could.
  1451. 1:45:08A few days later,
  1452. 1:45:12he and his two brothers leave the
  1453. 1:45:14kingdom on their own.
  1454. 1:45:19No one holds them back.
  1455. 1:45:26There is one behavior African wild dogs
  1456. 1:45:29excel at.
  1457. 1:45:32They step right onto the turf of those
  1458. 1:45:35who call the shots.
  1459. 1:45:39The formation stays low,
  1460. 1:45:44keeping their eyes peeled,
  1461. 1:45:48ears pinned flat.
  1462. 1:45:52The whole pack stays silent.
  1463. 1:45:58They eat faster than any other predator
  1464. 1:46:01in these parts.
  1465. 1:46:05Because on a lion pride's turf,
  1466. 1:46:11they are living on borrowed time.
  1467. 1:46:16In this realm, the weaker ones survive
  1468. 1:46:19by precision
  1469. 1:46:23while the leader is being put to the
  1470. 1:46:26test.
  1471. 1:46:30The pups still have to learn the ropes.
  1472. 1:46:36They are far too young for this.
  1473. 1:46:40The dry season doesn't hand out class
  1474. 1:46:44schedules.
  1475. 1:46:46Lesson one is moving under the radar.
  1476. 1:46:52The prey spotted them first
  1477. 1:46:55and the window of opportunity closed.
  1478. 1:47:00At the first sign of trouble,
  1479. 1:47:04the entire litter
  1480. 1:47:06bolts back to shelter.
  1481. 1:47:10They return to play fighting.
  1482. 1:47:14The game puts no food in anyone's belly,
  1483. 1:47:19but it lays the groundwork for future
  1484. 1:47:22authority.
  1485. 1:47:24For now,
  1486. 1:47:27the dominant female has only one path
  1487. 1:47:31left to reclaim her power.
  1488. 1:47:38She goes looking for water.
  1489. 1:47:42Every water hole nearby has dried out,
  1490. 1:47:46like the one that cost her credibility.
  1491. 1:47:50So, she chooses the only route left,
  1492. 1:47:54the flood plane to the north,
  1493. 1:47:57very far away.
  1494. 1:48:00This is the biggest gamble of her life.
  1495. 1:48:05The pack is already exhausted.
  1496. 1:48:08The pups are far too small for a journey
  1497. 1:48:11like this.
  1498. 1:48:14If she is wrong again,
  1499. 1:48:17what she loses is the whole pack.
  1500. 1:48:21She is not wrong.
  1501. 1:48:24She arrives worn down,
  1502. 1:48:27scraped raw,
  1503. 1:48:29and back in her old position.
  1504. 1:48:33The lead is hers again.
  1505. 1:48:40Two kingdoms,
  1506. 1:48:43two opposite endings.
  1507. 1:48:46One leader keeps the land
  1508. 1:48:50and loses what cannot be seen.
  1509. 1:48:54One leader loses all credibility,
  1510. 1:48:57then wins it back with water.
  1511. 1:49:02Both are renting their power
  1512. 1:49:05by the day.
  1513. 1:49:08On the African savannah,
  1514. 1:49:11no throne has ever been allowed to
  1515. 1:49:14sleep.
  1516. 1:49:15What keeps a king on top is the belief
  1517. 1:49:19of those around him.
  1518. 1:49:22That his strength is still intact.
  1519. 1:49:27That belief disappears in a single
  1520. 1:49:30moment
  1521. 1:49:32and no victory buys it back.
  1522. 1:49:37And you, if you had to choose between
  1523. 1:49:39the strongest leader
  1524. 1:49:43and the leader who always finds a way,
  1525. 1:49:47who would you follow?
  1526. 1:49:51Leave your answer in the comments.
  1527. 1:49:54For now, get ready for new horizons,
  1528. 1:50:01places beyond what people imagine.
  1529. 1:50:09Not every life and death chase fully
  1530. 1:50:12defines a safari,
  1531. 1:50:15for the journey unfolds a deeper
  1532. 1:50:18question.
  1533. 1:50:21What truly makes a safari trip
  1534. 1:50:24memorable?
  1535. 1:50:27Is it merely the breathless moments in
  1536. 1:50:30the vehicle?
  1537. 1:50:32Or is it also the way we travel,
  1538. 1:50:37cause to rest,
  1539. 1:50:41and choose the perfect time to set out?
  1540. 1:50:47A game drive usually begins very early
  1541. 1:50:50as the convoy rolls through the twilight
  1542. 1:50:53to reach the riverbank just in time for
  1543. 1:50:56sunrise.
  1544. 1:51:00Not everyone is fortunate enough to
  1545. 1:51:03catch that moment on their very first
  1546. 1:51:06try.
  1547. 1:51:11In the vehicle, a few rules are almost
  1548. 1:51:14non-negotiable.
  1549. 1:51:16Never stand up as the vehicle approaches
  1550. 1:51:19a viewing spot
  1551. 1:51:24and keep a clear distance from large
  1552. 1:51:26bushes so as not to block the line of
  1553. 1:51:29sight for both the group and the
  1554. 1:51:32animals.
  1555. 1:51:37Binoculars are an indispensable [music]
  1556. 1:51:39companion for any firsttime safari goer.
  1557. 1:51:49Many groups even [music] return to the
  1558. 1:51:51exact same area for days in a row simply
  1559. 1:51:55to keep following a story that began the
  1560. 1:51:59day before.
  1561. 1:52:02A truly complete safari is rarely
  1562. 1:52:05confined to just a single morning.
  1563. 1:52:14In South Luangua, Zambia,
  1564. 1:52:18where the walking safari is said to have
  1565. 1:52:20originated, it remains to this day one
  1566. 1:52:24of the most immersive ways to truly
  1567. 1:52:27connect with this pristine wilderness.
  1568. 1:52:31rather than merely viewing it through a
  1569. 1:52:34vehicle window.
  1570. 1:52:42The paradox lies in how one of Africa's
  1571. 1:52:46driest lands offers the finest wildlife
  1572. 1:52:49viewing right from the water as
  1573. 1:52:52travelers journey by boat along the Chob
  1574. 1:52:56River rather than by vehicle.
  1575. 1:53:15Farther south, the lower reaches of the
  1576. 1:53:18Zambesi River are almost entirely
  1577. 1:53:21inaccessible by road. To reach it,
  1578. 1:53:24travelers have only two options. A
  1579. 1:53:27flight on a light aircraft or paddling a
  1580. 1:53:30kayak upstream.
  1581. 1:53:34Surrounded by an isolated landscape
  1582. 1:53:37rarely matched anywhere else.
  1583. 1:53:51At the same time, South Luanga, the
  1584. 1:53:54birthplace of the walking safari, is
  1585. 1:53:57simultaneously a destination ranked
  1586. 1:54:00among the most luxurious
  1587. 1:54:03with a system of lodges set amidst a
  1588. 1:54:06lush green landscape for those willing
  1589. 1:54:10to pay for absolute privacy.
  1590. 1:54:25Not every destination follows that path.
  1591. 1:54:29In the Makasutu culture forest of
  1592. 1:54:32Gambia,
  1593. 1:54:33visitors can choose to stay at a small
  1594. 1:54:36riverside lodge.
  1595. 1:54:49There evenings welcome the sounds of
  1596. 1:54:52insects
  1597. 1:54:54and mornings welcome the calls of birds
  1598. 1:54:58in place of any other expensive
  1599. 1:55:01amenities.
  1600. 1:55:14As for Penari in Benin,
  1601. 1:55:17accommodations do not just stop at an
  1602. 1:55:21overnight stay. The surrounding space
  1603. 1:55:24bears a deep mark of indigenous culture,
  1604. 1:55:29inadvertently turning a safari trip into
  1605. 1:55:32a journey to discover the land.
  1606. 1:55:48Not every park is equally accessible.
  1607. 1:55:52Some places are quite well invested to
  1608. 1:55:55welcome international visitors, even
  1609. 1:55:58though the costs are usually slightly
  1610. 1:56:01higher than the regional average.
  1611. 1:56:19Not every month of the year yields an
  1612. 1:56:22equally rewarding safari.
  1613. 1:56:25In the Messiah Mara, the period from
  1614. 1:56:28July to October is when immense herds of
  1615. 1:56:32wilderbeast and zebra migrate on mass
  1616. 1:56:36across the landscape. Many seasoned
  1617. 1:56:39safari goers refer to this as the very
  1618. 1:56:43essence of a season of survival.
  1619. 1:57:03Elsewhere, the contrast lies more in the
  1620. 1:57:06landscape than in the abundance of
  1621. 1:57:09wildlife.
  1622. 1:57:10The arid winter gives way to lush green
  1623. 1:57:14bushland in the summer. endowing the
  1624. 1:57:17very same destination with two entirely
  1625. 1:57:21different faces depending on when you
  1626. 1:57:24visit
  1627. 1:57:34at Chob. However, it is during the dry
  1628. 1:57:37season that wildlife gathers in the
  1629. 1:57:40greatest numbers toward the northern
  1630. 1:57:42part of the park
  1631. 1:57:45as water sources there become scarcer
  1632. 1:57:48and more precious than anywhere else.
  1633. 1:57:58And not every destination lies along a
  1634. 1:58:01convenient route. Some require a full
  1635. 1:58:052-day overland journey or a domestic
  1636. 1:58:09flight just to set foot at the park
  1637. 1:58:12gates.
  1638. 1:58:15[laughter]
  1639. 1:58:19A memorable safari is rarely measured
  1640. 1:58:21merely by the number of species spotted
  1641. 1:58:25through binoculars.
  1642. 1:58:27It is also about how one chooses to
  1643. 1:58:29journey by vehicle, on foot or with the
  1644. 1:58:34quiet stroke of a paddle along the
  1645. 1:58:36river.
  1646. 1:58:43It is where they lay their heads at
  1647. 1:58:44night from a rustic bush camp to a
  1648. 1:58:48luxurious riverside lodge. And it is the
  1649. 1:58:52moment they choose to set out as the
  1650. 1:58:55entire land shifts its colors with the
  1651. 1:58:58seasons.
  1652. 1:59:10The journey begins in the Caribbean Sea
  1653. 1:59:13at an isolated island
  1654. 1:59:17where the humpback whale once wintered.
  1655. 1:59:27before continuing a migration thousands
  1656. 1:59:29of kilome long.
  1657. 1:59:33And it ends at a brackish swamp in
  1658. 1:59:35Florida.
  1659. 1:59:37There, a mystery will surface
  1660. 1:59:40beneath the murky water.
  1661. 1:59:44This is the story of predators
  1662. 1:59:47forced to adapt again and again
  1663. 1:59:51just to hold their place for one more
  1664. 1:59:53season.
  1665. 1:59:58Trinidad accounts for more than 80% of
  1666. 2:00:01all nesting leatherback turtles across
  1667. 2:00:04the entire Caribbean, second only to a
  1668. 2:00:07single beach in West Africa.
  1669. 2:00:13Ascension Island is home to the largest
  1670. 2:00:15seabird colony
  1671. 2:00:18left in the Atlantic.
  1672. 2:00:20That population once lost most of its
  1673. 2:00:22numbers in just half a century
  1674. 2:00:26before recovering on its own.
  1675. 2:00:31And in the Everglades, where the journey
  1676. 2:00:34ends, scientists for the first time
  1677. 2:00:38see the underwater world through the
  1678. 2:00:40eyes of a crocodile.
  1679. 2:00:46Trinidad, the Caribbean Sea.
  1680. 2:00:50The tide falls to its lowest point of
  1681. 2:00:52the day. The mangrove mud is exposed,
  1682. 2:00:57revealing a hunting ground with nowhere
  1683. 2:00:59to hide.
  1684. 2:01:01The tangled roots that once offered
  1685. 2:01:03shelter now become a prison maze. The
  1686. 2:01:06small pools shrink by the minute,
  1687. 2:01:11and any creature trapped inside has no
  1688. 2:01:14way out.
  1689. 2:01:17This is a trap, and it has just opened.
  1690. 2:01:22The name of this fish
  1691. 2:01:24comes from a visual mechanism rarely
  1692. 2:01:27seen in nature. Each eye is split in two
  1693. 2:01:31by a band of pigmented tissue with an
  1694. 2:01:34offcenter lens
  1695. 2:01:36flattened in the upper half and rounded
  1696. 2:01:40in the lower half.
  1697. 2:01:42Light from the air and light from the
  1698. 2:01:44water refract differently. The result is
  1699. 2:01:48that it sees both worlds at once. above
  1700. 2:01:52the surface and below it. Scientists
  1701. 2:01:55call this species the foureyed fish. But
  1702. 2:02:00a pair of eyes can only warn.
  1703. 2:02:03It cannot swim freely. And in a pool
  1704. 2:02:07that is slowly drying out, reaction
  1705. 2:02:10speed matters more than sight. Beneath
  1706. 2:02:13the thin layer of water, a spectacled
  1707. 2:02:15cayman patrols slowly,
  1708. 2:02:19barely leaving a ripple.
  1709. 2:02:22This is an ambush predator,
  1710. 2:02:25conserving every calorie, able to lie
  1711. 2:02:28still for hours, waiting for prey to
  1712. 2:02:30come close, rather than spend energy on
  1713. 2:02:33the chase.
  1714. 2:02:37The view from above gives them what the
  1715. 2:02:40Cayman does not have, the ability to see
  1716. 2:02:43the whole pool at once. One threat
  1717. 2:02:46hidden beneath the water, patient and
  1718. 2:02:49almost invisible.
  1719. 2:02:52Another threat watches from the air,
  1720. 2:02:55fast and with a sweeping view.
  1721. 2:02:59And in the middle, a creature with eyes
  1722. 2:03:02built to detect both, but without legs
  1723. 2:03:05quick enough to escape both at once.
  1724. 2:03:09There is not always a way out
  1725. 2:03:12for both sides at once.
  1726. 2:03:26This is the first rule of the Atlantic
  1727. 2:03:28Ocean.
  1728. 2:03:30Even the most refined adaptation
  1729. 2:03:33buys only one more chance, not a
  1730. 2:03:36guarantee. This is only a small battle.
  1731. 2:03:40Contained within a few meters of mud.
  1732. 2:03:44Farther out toward the open Atlantic,
  1733. 2:03:47the size of the arena grows, but the
  1734. 2:03:51rules of the game do not change. From
  1735. 2:03:54April to July each year, leatherback
  1736. 2:03:57turtle, the largest turtle still living
  1737. 2:04:00on Earth, hauls itself onto the sands of
  1738. 2:04:03Trinidad to lay its eggs.
  1739. 2:04:06This is one of the two busiest nesting
  1740. 2:04:09beaches for the species anywhere in the
  1741. 2:04:11world, second only to a stretch of coast
  1742. 2:04:15in West Africa. The sex of each
  1743. 2:04:18hatchling is not decided by its genes,
  1744. 2:04:21but by the temperature of the sand.
  1745. 2:04:25Above 30° C, most of the eggs hatch as
  1746. 2:04:28females. Below that, most are males.
  1747. 2:04:35An unusually hot season of sand can tilt
  1748. 2:04:38an entire generation, and no hatchling
  1749. 2:04:41has any say in the matter.
  1750. 2:04:44The moment they hatch, the young find
  1751. 2:04:47their way by the light reflected off the
  1752. 2:04:49surface of the sea. On the short journey
  1753. 2:04:52from nest to surf, most never reach the
  1754. 2:04:55water.
  1755. 2:04:58For those that survive to adulthood,
  1756. 2:05:01another navigation system takes over.
  1757. 2:05:04the ability to sense the Earth's
  1758. 2:05:07magnetic field. That system is so
  1759. 2:05:10precise that decades later, a female can
  1760. 2:05:15return to the very beach where she once
  1761. 2:05:17hatched across thousands of kilometers
  1762. 2:05:20of ocean. The leatherback is not the
  1763. 2:05:23only creature that makes this stretch of
  1764. 2:05:26the Caribbean so remarkable.
  1765. 2:05:29Just beneath the coastal waves lies one
  1766. 2:05:32of the most diverse coral reefs on the
  1767. 2:05:35planet. The Caribbean makes up only a
  1768. 2:05:37small fraction of the world's total
  1769. 2:05:40ocean area. Yet, it is home to around 75
  1770. 2:05:44species of reef building coral along
  1771. 2:05:47with more than 1,400
  1772. 2:05:50species of fish and marine mammals. In
  1773. 2:05:54all, more than 12,000 different species
  1774. 2:05:57of marine life have been recorded in
  1775. 2:06:00this region. But that diversity is under
  1776. 2:06:04serious threat. According to the
  1777. 2:06:06International Union for Conservation of
  1778. 2:06:08Nature, around 1 in 10 reef building
  1779. 2:06:11coral species in the Caribbean,
  1780. 2:06:14including elkhorn and stagghorn coral,
  1781. 2:06:18faces the risk of extinction. A typical
  1782. 2:06:21tropical coral reef can hold up to a
  1783. 2:06:25third of all the marine species known on
  1784. 2:06:28Earth. Yet, its area covers less than 1%
  1785. 2:06:32of the world's ocean floor.
  1786. 2:06:36This is why every square meter of reef
  1787. 2:06:39that is lost
  1788. 2:06:41carries a loss far greater than its true
  1789. 2:06:44size. The main cause of this wave of
  1790. 2:06:47decline is coral bleaching. When sea
  1791. 2:06:51temperatures rise abnormally by even 1
  1792. 2:06:53or 2° C, the coral expels the symbiotic
  1793. 2:06:58algae living within its own tissue.
  1794. 2:07:01Those algae provide most of the coral's
  1795. 2:07:04nourishment and color.
  1796. 2:07:06Without them, the coral turns white and
  1797. 2:07:10can starve within a few weeks.
  1798. 2:07:13Another shark also patrols this part of
  1799. 2:07:15the Caribbean in a way unlike any other.
  1800. 2:07:20scalloped hammerhead. Its flattened,
  1801. 2:07:23widened head is not just for looking
  1802. 2:07:26different. It holds thousands of
  1803. 2:07:28electrical sensors spread across its
  1804. 2:07:30surface. With them,
  1805. 2:07:34it can sweep a far wider band of the
  1806. 2:07:37seabed as it searches for prey hidden
  1807. 2:07:40beneath the sand.
  1808. 2:07:42From this nesting beach, the current
  1809. 2:07:46carries the story further.
  1810. 2:07:48Not everything in the Caribbean stays in
  1811. 2:07:50the Caribbean.
  1812. 2:07:52Riding the same waters,
  1813. 2:07:55a pod of common dolphin,
  1814. 2:07:58which can number in the hundreds, is
  1815. 2:08:00hunting together across the open ocean.
  1816. 2:08:04They often travel with schools of flying
  1817. 2:08:07fish.
  1818. 2:08:09That gliding ability evolved as a direct
  1819. 2:08:12response
  1820. 2:08:14to the constant pressure of predation.
  1821. 2:08:17A chase lasting millions of years has
  1822. 2:08:21turned pectoral fins into a pair of
  1823. 2:08:23wings.
  1824. 2:08:26Silver Bank, the shallow waters north of
  1825. 2:08:29the Dominican Republic, is where around
  1826. 2:08:333,000 humpback whale gather each winter
  1827. 2:08:36from December to April. They come here
  1828. 2:08:39to mate and give birth in the warm
  1829. 2:08:41water, safer for the young. A newly
  1830. 2:08:45carved mother whale faces a harsh
  1831. 2:08:47tradeoff. The warm Caribbean water is
  1832. 2:08:51safer from orca, but holds almost no
  1833. 2:08:54food.
  1834. 2:08:56The calf must grow quickly enough
  1835. 2:08:59to withstand the migration ahead before
  1836. 2:09:02its mother runs out of her energy
  1837. 2:09:04reserves.
  1838. 2:09:07Throughout that journey,
  1839. 2:09:09orca remain the greatest threat to the
  1840. 2:09:11young calves in the pod. This is the
  1841. 2:09:14true bridge that connects the Caribbean
  1842. 2:09:17to the rest of the Atlantic Ocean.
  1843. 2:09:20Not a border drawn on a map, but a
  1844. 2:09:24living migration route repeated every
  1845. 2:09:26year.
  1846. 2:09:28It stretches from the warm waters where
  1847. 2:09:30life begins
  1848. 2:09:33to the cold waters where life is
  1849. 2:09:35nourished.
  1850. 2:09:37With danger waiting at both ends, the
  1851. 2:09:40Gulf Stream carries warm water
  1852. 2:09:44along with nutrients and tropical life
  1853. 2:09:47running up the eastern coast of the
  1854. 2:09:49United States and then crossing the
  1855. 2:09:51whole Atlantic Ocean as far as Europe.
  1856. 2:09:55Where the warm water meets colder water,
  1857. 2:09:58eddies form, drawing nutrients up from
  1858. 2:10:01the depths to the surface.
  1859. 2:10:06That is why some stretches of sea along
  1860. 2:10:09this current are among the richest in
  1861. 2:10:11life in the Atlantic Ocean,
  1862. 2:10:14even far from any reef or tropical
  1863. 2:10:17shore.
  1864. 2:10:19The Saraso Sea is the only sea on the
  1865. 2:10:22planet bounded by no coastline at all.
  1866. 2:10:26Its edges are defined only by the four
  1867. 2:10:28currents that surround it. Spreading
  1868. 2:10:31across more than 5 million square kilm
  1869. 2:10:34of water. The foundation of an entire
  1870. 2:10:37ecosystem here
  1871. 2:10:39is sargasm.
  1872. 2:10:42A seaweed that drifts freely for its
  1873. 2:10:45whole life,
  1874. 2:10:46never needing to anchor to the seabed or
  1875. 2:10:49any rocky shore.
  1876. 2:10:52For sea turtles,
  1877. 2:10:54this mat of seaweed matters more than
  1878. 2:10:56anyone once imagined.
  1879. 2:10:59But the greatest mystery of this sea
  1880. 2:11:01belongs to a species that almost never
  1881. 2:11:03lives here year round. The freshwater
  1882. 2:11:06eel of Europe and North America. This is
  1883. 2:11:10the only known breeding ground for both
  1884. 2:11:13of those endangered eel species.
  1885. 2:11:16After years of maturing in rivers
  1886. 2:11:18thousands of kilometers away, they turn
  1887. 2:11:22back to this sea to spawn
  1888. 2:11:24and then end their lives.
  1889. 2:11:28A journey that can last up to 25 years
  1890. 2:11:32only to end in the place where it began.
  1891. 2:11:36Drifting among the seaweed mats is a
  1892. 2:11:39creature often mistaken for a single
  1893. 2:11:41jellyfish.
  1894. 2:11:43The Portuguese man owe war. In truth, it
  1895. 2:11:46is a colony of many specialized
  1896. 2:11:48individuals
  1897. 2:11:50living in close partnership. Each
  1898. 2:11:53individual takes on its own function
  1899. 2:11:56from floating
  1900. 2:11:58to catching prey to digestion.
  1901. 2:12:01Its tentacles carry venom strong enough
  1902. 2:12:05to cause intense pain in a human. Even
  1903. 2:12:09the most passive drifter of the open
  1904. 2:12:12ocean can be a dangerous predator.
  1905. 2:12:16Follow that current onward. More than
  1906. 2:12:181,600
  1907. 2:12:20km to the south. In the open sea, with
  1908. 2:12:25no other land in sight,
  1909. 2:12:27a small volcanic island rises.
  1910. 2:12:31Ascension Island.
  1911. 2:12:33Seabirds are not the only residents that
  1912. 2:12:36turn this isolated island into a
  1913. 2:12:39gathering point for life. Ascension
  1914. 2:12:42Island is also the second largest
  1915. 2:12:44nesting site for the green turtle in the
  1916. 2:12:49entire Atlantic Ocean.
  1917. 2:12:52Each breeding season, the island records
  1918. 2:12:56between 7,500 and 30,000 nests. Each
  1919. 2:13:00nest holding on average more than 120
  1920. 2:13:04eggs.
  1921. 2:13:06To reach here, each female must swim
  1922. 2:13:10more than 2,400
  1923. 2:13:12km from the waters of Brazil,
  1924. 2:13:15returning to the very island where she
  1925. 2:13:18once hatched. Once every 3 to 4 years,
  1926. 2:13:22but the cost of that journey is high.
  1927. 2:13:26Only about 1% of the hatchlings survive
  1928. 2:13:29to adulthood.
  1929. 2:13:31Those fortunate enough to cross that
  1930. 2:13:33threshold can live up [music] to 80
  1931. 2:13:36years.
  1932. 2:13:38The island is home to the largest
  1933. 2:13:40remaining population
  1934. 2:13:42of the si turn in the Atlantic Ocean.
  1935. 2:13:46This bird has an almost unimaginable
  1936. 2:13:49ability. After leaving the nest, they
  1937. 2:13:52can stay in the air for years on end,
  1938. 2:13:55landing only on the water to feed and
  1939. 2:13:58never touching down on land until they
  1940. 2:14:00return to nest. But that population was
  1941. 2:14:04once far larger. In the 1940s, this
  1942. 2:14:07island was home
  1943. 2:14:09to more than 2 million seabirds. The
  1944. 2:14:12cause was feral cats brought to the
  1945. 2:14:15island by people along with the
  1946. 2:14:17harvesting of birds eggs in the past.
  1947. 2:14:20From 1990 to 2013
  1948. 2:14:23after the feral cats were removed from
  1949. 2:14:26the island, the seabird population
  1950. 2:14:29steadied once again.
  1951. 2:14:31Even on this rare safe island,
  1952. 2:14:35competition never disappears. It only
  1953. 2:14:38changes form. The frigat bird cannot
  1954. 2:14:41dive to catch its own fish. A form of
  1955. 2:14:44organized theft playing out every day in
  1956. 2:14:49the skies above the most peaceful island
  1957. 2:14:52in the South Atlantic.
  1958. 2:14:58Everything mentioned so far belongs to
  1959. 2:15:01the surface layer of the Atlantic.
  1960. 2:15:04But most of the life in this ocean lies
  1961. 2:15:07nowhere near the surface.
  1962. 2:15:10From 200 to 1,000 m down, there is a
  1963. 2:15:14layer of water known as the twilight
  1964. 2:15:16zone, where sunlight fades to a dim
  1965. 2:15:19trace before vanishing entirely. This
  1966. 2:15:23layer makes up only about 20% of the
  1967. 2:15:25global ocean's volume. Yet, it holds up
  1968. 2:15:29to 90% of the total fish biomass.
  1969. 2:15:33In the entire world, roughly 10 billion
  1970. 2:15:36tons,
  1971. 2:15:39a food web almost invisible from the
  1972. 2:15:42surface,
  1973. 2:15:44feeding directly.
  1974. 2:15:46The far more familiar surface predators,
  1975. 2:15:50among them, the tuna.
  1976. 2:15:52One of the strangest residents of this
  1977. 2:15:55layer is the angler fish. In some
  1978. 2:15:58species, the male is many times smaller
  1979. 2:16:03and permanently fuses his living tissue
  1980. 2:16:06with the female solely to sustain the
  1981. 2:16:09ability to reproduce.
  1982. 2:16:12Each night, billions of creatures from
  1983. 2:16:14this deep layer swim up near the surface
  1984. 2:16:18to feed, then descend again before dawn.
  1985. 2:16:22Scientists regard this as the largest
  1986. 2:16:25migration
  1987. 2:16:26of any animal on the planet, repeating
  1988. 2:16:29steadily every 24 hours. In the process,
  1989. 2:16:33they carry carbon from the surface down
  1990. 2:16:35to the deep, helping to lock away 2 to 6
  1991. 2:16:39billion tons of carbon each year. In
  1992. 2:16:43waters deeper still, the sperm whale can
  1993. 2:16:47dive to more than 2,000 m,
  1994. 2:16:50holding its breath for nearly 2 hours at
  1995. 2:16:52a time just to hunt the giant squid.
  1996. 2:16:56Most adult sperm whales carry circular
  1997. 2:16:59scars on their skin.
  1998. 2:17:02Marks left by the suckers of the very
  1999. 2:17:05giant squid they once wrestled. It is
  2000. 2:17:09evidence of a battle fought entirely in
  2001. 2:17:12the dark.
  2002. 2:17:15Even coral reefs do not exist only in
  2003. 2:17:19sunlit tropical waters.
  2004. 2:17:22They live by filtering the very nutrient
  2005. 2:17:25particles drifting down from the layers
  2006. 2:17:28above,
  2007. 2:17:30including the remains of creatures that
  2008. 2:17:32migrated through the night.
  2009. 2:17:38Back near the surface, another migration
  2010. 2:17:42far easier to observe is taking place
  2011. 2:17:45just off Ascension.
  2012. 2:17:49Each year, right around Easter,
  2013. 2:17:53another migration unfolds off Ascension.
  2014. 2:17:57Their gills are more than 30 times
  2015. 2:17:59larger than those of most fish of
  2016. 2:18:02similar size
  2017. 2:18:04to take in enough oxygen for extremely
  2018. 2:18:07fast swimming.
  2019. 2:18:09Their hearts are up to 10 times larger
  2020. 2:18:12and their blood is kept warmer
  2021. 2:18:15thanks to a countercurren heat exchange
  2022. 2:18:18system lying just beneath the muscle.
  2023. 2:18:21This trait is found in only a very few
  2024. 2:18:24fish, among them the great white shark.
  2025. 2:18:27The yellow fin tuner operates like a
  2026. 2:18:30machine optimized for one thing alone,
  2027. 2:18:34speed, and the ability to sustain that
  2028. 2:18:37speed across thousands of kilometers
  2029. 2:18:40without rest.
  2030. 2:18:42But even speed has its equal. In the
  2031. 2:18:45waters around Ascension, there is also
  2032. 2:18:48the wahoo, one of the fastest swimming
  2033. 2:18:50fish in the ocean. It is also the
  2034. 2:18:53fastest growing member of the entire
  2035. 2:18:55mackerel and tuna family, reaching the
  2036. 2:18:58ability to reproduce after only 12
  2037. 2:19:01months of age.
  2038. 2:19:03A prey fast, strong, and early to
  2039. 2:19:06mature.
  2040. 2:19:08What predator has the power to bring
  2041. 2:19:10down a warmblooded creature
  2042. 2:19:14of high speed evolved solely to flee?
  2043. 2:19:19The answer does not come from speed.
  2044. 2:19:22It comes from numbers
  2045. 2:19:24and a sensory organ far beyond human
  2046. 2:19:27imagination.
  2047. 2:19:29The Galapagus shark, a predator that
  2048. 2:19:32wins through sheer numbers,
  2049. 2:19:35and a sensory tool that is almost
  2050. 2:19:37impossible to believe.
  2051. 2:19:40Nearly 2/3 of the Galapagus shark's
  2052. 2:19:42brain
  2053. 2:19:44is devoted to smell. Its sense of smell
  2054. 2:19:48surpasses a human's by 10,000 times. It
  2055. 2:19:51can detect a single drop of blood
  2056. 2:19:53diluted across an entire Olympic
  2057. 2:19:56swimming pool.
  2058. 2:19:57But that is only its first line of
  2059. 2:19:59defense.
  2060. 2:20:01At closer range, hundreds of tiny
  2061. 2:20:04sensory organs surround its snout
  2062. 2:20:08known as the ampuli of lorenzini.
  2063. 2:20:12They can detect the faintest electrical
  2064. 2:20:14pulses
  2065. 2:20:16given off by the very heartbeat and
  2066. 2:20:18muscle movements of prey.
  2067. 2:20:21It senses prey even when that prey lies
  2068. 2:20:24motionless and hidden completely from
  2069. 2:20:27view. There is nowhere to hide from a
  2070. 2:20:30body that still holds life.
  2071. 2:20:33In the waters around Ascension,
  2072. 2:20:36the Galapagus shark has also been
  2073. 2:20:38recorded showing a rare learner
  2074. 2:20:41behavior.
  2075. 2:20:43They learn to link the sound of fishing
  2076. 2:20:45boat engines
  2077. 2:20:47with the chance of leftover food and
  2078. 2:20:51begin to gather whenever they hear that
  2079. 2:20:53sound,
  2080. 2:20:55even without ever seeing or smelling any
  2081. 2:20:57prey.
  2082. 2:21:09Nothing is left large enough to
  2083. 2:21:11identify.
  2084. 2:21:13But this is not what has drawn the
  2085. 2:21:14sharks together in such numbers. The
  2086. 2:21:17wahoo is only a warning, a light snack
  2087. 2:21:21before a far larger hunt. The pack's
  2088. 2:21:25true target is still swimming up ahead.
  2089. 2:21:29But in these waters,
  2090. 2:21:31everyone is hungry.
  2091. 2:21:34After escaping the ring of Galapagus
  2092. 2:21:37sharks,
  2093. 2:21:39the tuna find their own lunch, a bait
  2094. 2:21:42ball. The feeding happens so fast that
  2095. 2:21:46if you miss it, no one would know what
  2096. 2:21:49had just taken place. But one hunter is
  2097. 2:21:52fast enough to keep up with it all. A
  2098. 2:21:55maco shark, the fastest of the ocean's
  2099. 2:21:58most fearsome predators. The feast ahead
  2100. 2:22:02will fill its hungry stomach with prey
  2101. 2:22:05weighing 400 kg.
  2102. 2:22:08Through a process of convergent
  2103. 2:22:09evolution, the tuna also has friction
  2104. 2:22:12reducing skin
  2105. 2:22:15muscle concentrated in the tail and the
  2106. 2:22:19ability to warm its blood.
  2107. 2:22:21Just like the mako,
  2108. 2:22:24the high-speed predator has failed. But
  2109. 2:22:27the story in the Atlantic is not over.
  2110. 2:22:30Who do you think is truly the most
  2111. 2:22:33formidable predator among these ocean
  2112. 2:22:36giants?
  2113. 2:22:38Leave your prediction before the answer
  2114. 2:22:40is revealed.
  2115. 2:22:48Midway through that journey
  2116. 2:22:51lies a river,
  2117. 2:22:55dangerous river in all of Africa.
  2118. 2:23:01But before that fateful crossing,
  2119. 2:23:05three smaller trials
  2120. 2:23:09will decide who is strong enough to go
  2121. 2:23:12on.
  2122. 2:23:26In its first days of life,
  2123. 2:23:31a gazelle calf gives off almost no
  2124. 2:23:35scent.
  2125. 2:23:39It is the first survival strategy
  2126. 2:23:44that nature grants to species born on
  2127. 2:23:47the open plains
  2128. 2:23:52where there is nowhere to hide but
  2129. 2:23:56stillness itself.
  2130. 2:24:00It is not only the Thompson's Gazelle.
  2131. 2:24:07Most antelope of the Serenetti rely on
  2132. 2:24:11this same tactic in their first week of
  2133. 2:24:15life.
  2134. 2:24:22It is also why most young here are born
  2135. 2:24:26almost all at once
  2136. 2:24:29within a short window each year.
  2137. 2:24:34the more calves that appear at the same
  2138. 2:24:37time,
  2139. 2:24:41>> the lower the odds that any single one
  2140. 2:24:45is taken.
  2141. 2:24:51But the spotted hyena does not rely on
  2142. 2:24:55scent alone.
  2143. 2:24:59It can go hungry for days on end.
  2144. 2:25:02[laughter]
  2145. 2:25:03And still it keeps searching.
  2146. 2:25:11The mother's answer is not speed. It
  2147. 2:25:14lies in a trade, [laughter]
  2148. 2:25:25making herself the more visible target
  2149. 2:25:29so her calf can stay invisible.
  2150. 2:25:47>> [music]
  2151. 2:25:49>> For a body weighing tens of kilograms,
  2152. 2:25:53every chase burns a precious energy
  2153. 2:25:55reserve.
  2154. 2:25:57A reserve not easily replaced [music]
  2155. 2:26:00in the dry season.
  2156. 2:26:10When both water and prey run scarce,
  2157. 2:26:17that is why a failed hunt [laughter]
  2158. 2:26:22is more than a moment of disappointment.
  2159. 2:26:26It is a calculation that ends in loss.
  2160. 2:26:36A few minutes of useless pursuit
  2161. 2:26:38[laughter]
  2162. 2:26:40and the hyena is forced to give up.
  2163. 2:26:44Not every predator accepts defeat so
  2164. 2:26:47easily. [laughter]
  2165. 2:26:49The hyena knows other chances remain.
  2166. 2:26:54But once the birthing season passes,
  2167. 2:26:58the struggle to survive [laughter] will
  2168. 2:27:00no longer turn on the number of
  2169. 2:27:03newborns.
  2170. 2:27:15>> [music]
  2171. 2:27:23[music]
  2172. 2:27:26>> Not every relationship on the plains is
  2173. 2:27:29hunter and hunted.
  2174. 2:27:35Zebra eat the older, taller, tougher
  2175. 2:27:38grass.
  2176. 2:27:42Unknowingly clearing the way to the
  2177. 2:27:44younger blades beneath,
  2178. 2:27:48the wilderbeasts preferred food.
  2179. 2:27:52In return, the overwhelming numbers of
  2180. 2:27:55the wilderbeast herd
  2181. 2:27:58become a natural shield for both
  2182. 2:28:01species.
  2183. 2:28:05On the other side of the food chain,
  2184. 2:28:08every predator struggles too.
  2185. 2:28:12The cheetah is the most efficient hunter
  2186. 2:28:15here [music]
  2187. 2:28:20and nearly half of its chases end in a
  2188. 2:28:22catch.
  2189. 2:28:25But efficiency does not mean safety.
  2190. 2:28:30Leopards, hyenas, and jackals
  2191. 2:28:35are always lurking, ready to steal that
  2192. 2:28:38prize at any moment.
  2193. 2:28:44And higher than all of them, vultures
  2194. 2:28:47wait in the sky.
  2195. 2:28:52No matter whose kill it was,
  2196. 2:28:56a vulture can spot a carcass from a
  2197. 2:28:59great distance
  2198. 2:29:01thanks to [music] extraordinary
  2199. 2:29:03eyesight.
  2200. 2:29:07That gift makes it always among the
  2201. 2:29:10first to arrive, though never the first
  2202. 2:29:13to strike.
  2203. 2:29:16No species in this food chain ever eats
  2204. 2:29:20alone.
  2205. 2:29:29At midday,
  2206. 2:29:31when the ground bakes under the harshest
  2207. 2:29:34sun of the day,
  2208. 2:29:38most hunting comes to a halt.
  2209. 2:29:44Both predator and prey shift to the two
  2210. 2:29:48ends of the day,
  2211. 2:29:51dawn and dusk,
  2212. 2:29:55when the heat has not yet risen or has
  2213. 2:29:58already faded.
  2214. 2:30:02It is also why the decisive moments of
  2215. 2:30:05the entire migration
  2216. 2:30:13almost always fall within those same
  2217. 2:30:16hours.
  2218. 2:30:20[laughter]
  2219. 2:30:24[music]
  2220. 2:30:32The hyena is not only a hunter.
  2221. 2:30:37Part of its diet comes from stealing or
  2222. 2:30:41scavenging the kills of others.
  2223. 2:30:45That double role, both hunter and
  2224. 2:30:48scavenger,
  2225. 2:30:52lets it live at higher densities
  2226. 2:30:55than most other large predators [music]
  2227. 2:30:58in the same region.
  2228. 2:31:08Not every resident here takes part in
  2229. 2:31:12the chase.
  2230. 2:31:14Many water birds spend their whole lives
  2231. 2:31:17along the banks of the Mara.
  2232. 2:31:21Wholly dependent on this rare water
  2233. 2:31:26to survive the dry season.
  2234. 2:31:30The river ahead is not only a dangerous
  2235. 2:31:33boundary,
  2236. 2:31:35it is also a source of life for dozens
  2237. 2:31:38of other species.
  2238. 2:31:45Hunting alone, like the cheetah,
  2239. 2:31:49means all the risk rests on a single
  2240. 2:31:53animal.
  2241. 2:31:55Fast but fragile.
  2242. 2:32:02Hunting in a group like the lion spreads
  2243. 2:32:06that risk across many,
  2244. 2:32:12but the reward must be shared among more
  2245. 2:32:15mouths.
  2246. 2:32:18No strategy is ever fully superior.
  2247. 2:32:25Each pays its own [music] price.
  2248. 2:32:28and only constant adaptation
  2249. 2:32:32keeps a species alive.
  2250. 2:32:38Some species choose an entirely
  2251. 2:32:41different strategy to survive in this
  2252. 2:32:43[music] land.
  2253. 2:32:48Banded monguses move in troops of
  2254. 2:32:51dozens.
  2255. 2:32:53a social structure strong enough to face
  2256. 2:32:56predators many times their own weight.
  2257. 2:33:02Group coordination, it turns out,
  2258. 2:33:07is no privilege of the big cats alone.
  2259. 2:33:14If every predator must struggle to
  2260. 2:33:16survive,
  2261. 2:33:19what truly lets one species master the
  2262. 2:33:22game.
  2263. 2:33:32The lamb is the only big cat that lives
  2264. 2:33:35in a pride
  2265. 2:33:41and maintains close social bonds between
  2266. 2:33:44its members.
  2267. 2:33:49That is what drives them to develop a
  2268. 2:33:51different hunting tactic,
  2269. 2:33:55dividing roles among members of the
  2270. 2:33:57pride.
  2271. 2:34:03something usually seen only in predators
  2272. 2:34:06that live in groups.
  2273. 2:34:11Her role is not to make the kill, but to
  2274. 2:34:14drive the prey in the right direction.
  2275. 2:34:26not choose at random.
  2276. 2:34:31Search for the one that is slower,
  2277. 2:34:33older,
  2278. 2:34:38or drifting away from the protection of
  2279. 2:34:40the group.
  2280. 2:34:44A single wrong choice of target can cost
  2281. 2:34:48the entire pride a meal.
  2282. 2:35:14A full grown wilderbeast goes down.
  2283. 2:35:19Enough to feed an entire lion family for
  2284. 2:35:22days.
  2285. 2:35:25Why do you think the lion is the only
  2286. 2:35:28big cat to hunt as a group?
  2287. 2:35:33Leave a comment below.
  2288. 2:35:38But cooperation within a single species
  2289. 2:35:41is only half the rule in this land.
  2290. 2:35:50But the pressure from behind allows no
  2291. 2:35:53hesitation for long.
  2292. 2:36:00At last, the whole herd has been waiting
  2293. 2:36:03for.
  2294. 2:36:11[music]
  2295. 2:36:21A grown crocodile can live for decades,
  2296. 2:36:26returning to this very stretch of river
  2297. 2:36:28with each migration.
  2298. 2:36:32That patience is a kind of strategy
  2299. 2:36:36other species cannot copy.
  2300. 2:36:40Waiting for the moment then finishing it
  2301. 2:36:44is its most successful tactic of all.
  2302. 2:36:50Crocodile and lion will usually choose
  2303. 2:36:54peace.
  2304. 2:36:58Together they exploit a single weakness.
  2305. 2:37:02The moment when sheer numbers are forced
  2306. 2:37:05into one narrow stretch of river.
  2307. 2:37:13But there are moments when a carcass
  2308. 2:37:18lies stranded between the two
  2309. 2:37:22sparking contests of power decided
  2310. 2:37:26entirely by size.
  2311. 2:37:30And what remains beneath the river is
  2312. 2:37:34never lost.
  2313. 2:37:36The dead feed the vultures in the sky,
  2314. 2:37:41the fish below the surface, and even the
  2315. 2:37:45smallest creatures.
  2316. 2:37:48No one ever notices.
  2317. 2:38:10This is the story of the moment. Prey
  2318. 2:38:14strikes back.
  2319. 2:38:33lead lioness of the Kinga pride.
  2320. 2:38:40One of the most feared hunting dynasties
  2321. 2:38:44in the Zambesi Valley, a pride is built
  2322. 2:38:48around its females.
  2323. 2:38:55Mother, daughters, sisters, four to six
  2324. 2:38:59adults,
  2325. 2:39:05hunting the same ground and raising the
  2326. 2:39:08cubs together.
  2327. 2:39:15Sappy sits at the top of that family.
  2328. 2:39:18She is not the villain here.
  2329. 2:39:25And fighting her off with everything you
  2330. 2:39:27have
  2331. 2:39:33is simply the price of one more day
  2332. 2:39:36alive.
  2333. 2:39:38Whose side are you on?
  2334. 2:39:43in Zimbabwe's Zambzi Valley and further
  2335. 2:39:47north in Tanzania's Rua National Park.
  2336. 2:39:56And where prey gathers, hunters are
  2337. 2:39:59already waiting.
  2338. 2:40:04An entire web of life compresses around
  2339. 2:40:08the last few pools.
  2340. 2:40:15Grazers come to drink. Predators come to
  2341. 2:40:19wait.
  2342. 2:40:21Hyenas and vultures come for whatever is
  2343. 2:40:25left. Nobody can avoid that appointment.
  2344. 2:40:35Even knowing that the walk down to the
  2345. 2:40:38water may be the last walk of their
  2346. 2:40:42lives.
  2347. 2:40:48Buffalo herds swell past a thousand
  2348. 2:40:52animals,
  2349. 2:40:58couring down the same old trails. One
  2350. 2:41:02water source
  2351. 2:41:06and thousands of prey animals forced out
  2352. 2:41:10of hiding.
  2353. 2:41:14The dry season redraws the stage,
  2354. 2:41:20then pushes everyone out into the open.
  2355. 2:41:26And on that stage, the rules are about
  2356. 2:41:30to be rewritten.
  2357. 2:41:34What do you think? Does the brutal heat
  2358. 2:41:37of the dry season
  2359. 2:41:42make an animal weaker or harder?
  2360. 2:41:47Leave your answer below.
  2361. 2:42:01His
  2362. 2:42:16family has been standing at the edge of
  2363. 2:42:19the water hole for almost an hour.
  2364. 2:42:27Those stripes are not decoration.
  2365. 2:42:33When a herd of zebra stands shouldertosh
  2366. 2:42:36shoulder and moves, the black and white
  2367. 2:42:40blurs into one shifting mass.
  2368. 2:42:50and a hunter struggles to lock onto any
  2369. 2:42:54single animal.
  2370. 2:42:59That is why zebra are rarely alone.
  2371. 2:43:03Their strength
  2372. 2:43:05is in staying together. They take turns,
  2373. 2:43:10one head down to drink, another head up
  2374. 2:43:14on watch.
  2375. 2:43:18Lora steps forward out of that circle of
  2376. 2:43:22safety. Only a few steps.
  2377. 2:43:28And in that instant, the darkness beside
  2378. 2:43:31the grass moves.
  2379. 2:43:37For most prey, this moment is the end.
  2380. 2:43:55Laader twists his hips at the last
  2381. 2:43:58possible second.
  2382. 2:44:01One moment, but that is all La Rayada
  2383. 2:44:04needs.
  2384. 2:44:11The hunter is left alone at the water
  2385. 2:44:14with an old lesson she has just been
  2386. 2:44:16taught again.
  2387. 2:44:22Sometimes turning to run is more
  2388. 2:44:25dangerous than turning to fight.
  2389. 2:44:30That was the first kick. There will be
  2390. 2:44:33more. And not all of them are about to
  2391. 2:44:36escape.
  2392. 2:44:48But before other legs speak, you need to
  2393. 2:44:52know why tonight is this tense.
  2394. 2:45:02Lions are one of the few cats on Earth
  2395. 2:45:06that choose to live in groups.
  2396. 2:45:11The heart of a pride is its females,
  2397. 2:45:15usually related by blood, hunting
  2398. 2:45:18together and raising the pride's cub.
  2399. 2:45:31Across the grass lies the Mazonga pride.
  2400. 2:45:35Two lion families
  2401. 2:45:39gnored by the same hunger.
  2402. 2:45:53Hold it and you eat. Lose it and you
  2403. 2:45:57wonder, hungry, growing weaker.
  2404. 2:46:05Nobody understands that better than
  2405. 2:46:08Sapp.
  2406. 2:46:26By the time the Mazonga pride arrives,
  2407. 2:46:36the best ground already has an owner.
  2408. 2:46:50While the two prides are still measuring
  2409. 2:46:52each other, another opportunity appears
  2410. 2:46:55on the horizon.
  2411. 2:47:02A wilderbeast herd is crossing open
  2412. 2:47:06ground. In East Africa, these herds can
  2413. 2:47:10number hundreds of thousands.
  2414. 2:47:13At the height of the migration, a living
  2415. 2:47:16river running across the savannah.
  2416. 2:47:23Their migration is one of the greatest
  2417. 2:47:26displays of life on the planet.
  2418. 2:47:36Inside that enormous current, each
  2419. 2:47:39animal is only a dot.
  2420. 2:47:43And that is the whole strategy.
  2421. 2:47:51A lion cannot eat a herd. It can only
  2422. 2:47:55pick one. So the survival rule for a
  2423. 2:47:59wilderbeast
  2424. 2:48:01is very simple.
  2425. 2:48:05But the moment one is cut out, every
  2426. 2:48:09advantage flips in an instant.
  2427. 2:48:19He has just covered a long stretch of
  2428. 2:48:21ground and his legs are heavy. To the
  2429. 2:48:25watching lioness, that is an invitation.
  2430. 2:48:44When the lioness closes to within
  2431. 2:48:46touching distance of his flank,
  2432. 2:49:11>> [music]
  2433. 2:49:16>> For La Sentinela, a female ostrich, legs
  2434. 2:49:20are everything.
  2435. 2:49:24alone. No herd, no crowd to disappear
  2436. 2:49:28into.
  2437. 2:49:30Only her, the nest, and the horizon wide
  2438. 2:49:34open on every side.
  2439. 2:49:41If she runs, she leaves behind an entire
  2440. 2:49:45generation that has not yet [music]
  2441. 2:49:48hatched.
  2442. 2:49:54And not for many species, the drive to
  2443. 2:49:57protect the next generation
  2444. 2:50:00is stronger than the drive to stay
  2445. 2:50:02alive. [music]
  2446. 2:50:10On the African savannah, the spotted
  2447. 2:50:13hyena is not the cowardly scavenger.
  2448. 2:50:18[music]
  2449. 2:50:23But reputation has made of it.
  2450. 2:50:27They live in clans that can run to
  2451. 2:50:30dozens of animals.
  2452. 2:50:35Ruled by the females,
  2453. 2:50:38they hunt for themselves far more often
  2454. 2:50:41than they steal.
  2455. 2:50:44And a hyena's jaws can crush a fiber.
  2456. 2:50:57up.
  2457. 2:51:16Lentinella returns to her nest. Her neck
  2458. 2:51:21rises again.
  2459. 2:51:24Her eyes sweep the horizon again.
  2460. 2:51:29The watch has never stopped.
  2461. 2:51:41But if every kick landed, this story
  2462. 2:51:44would be a lie.
  2463. 2:51:49The truth [music] of the savannah is
  2464. 2:51:52harder than that.
  2465. 2:51:55The giraffe is the tallest land animal
  2466. 2:51:58alive.
  2467. 2:52:00An adult can stand 5 to 6 m, high enough
  2468. 2:52:05to look over the tops of most savannah
  2469. 2:52:07[music] trees.
  2470. 2:52:12But a giraffe calf has none of that yet.
  2471. 2:52:15[music] At birth, it falls nearly 2 m to
  2472. 2:52:18the ground, and within an hour, it has
  2473. 2:52:21to learn [music] to stand.
  2474. 2:52:23Those first hours are the most fragile
  2475. 2:52:26of its life. Its legs still shake. All
  2476. 2:52:31it knows is to stay close [music] to its
  2477. 2:52:34mother.
  2478. 2:52:37>> The Kavinga pride has found its target.
  2479. 2:52:43[music]
  2480. 2:52:46For the pride, this is the easiest meal
  2481. 2:52:48the dry season can offer.
  2482. 2:52:59Lions are masters at reading weakness.
  2483. 2:53:03[music]
  2484. 2:53:09That mother has seconds to decide.
  2485. 2:53:13[music] Run and probably save herself
  2486. 2:53:18or stand [music] and gamble everything.
  2487. 2:53:24Reaguardiana,
  2488. 2:53:26that is her name. [music]
  2489. 2:53:37[music]
  2490. 2:53:44[music]
  2491. 2:53:53One kick does not win the war, but it
  2492. 2:53:57buys hope. For a giraffe mother, time is
  2493. 2:54:01worth more than victory.
  2494. 2:54:04[music]
  2495. 2:54:09Every second [music] her calf stays
  2496. 2:54:11standing is a second it can grow a
  2497. 2:54:14little more. Get a [music] little
  2498. 2:54:17stronger, a little closer to the day its
  2499. 2:54:20own legs are enough to defend it.
  2500. 2:54:26Do you believe the love of a wild animal
  2501. 2:54:30carries a soul just as pure as our own?
  2502. 2:54:46Now back to the harshest place of all,
  2503. 2:54:50the dry riverbed,
  2504. 2:54:57where the season has squeezed out the
  2505. 2:55:00last drop,
  2506. 2:55:02leaving only stone cracked mud and heat
  2507. 2:55:12overhead. Vultures have begun to circle.
  2508. 2:55:21They read the savannah from above and
  2509. 2:55:24they know that where an animal stands
  2510. 2:55:27alone with nowhere left to go.
  2511. 2:55:39No shade, no wind,
  2512. 2:55:43only hard sunlight and the breathing of
  2513. 2:55:47bodies getting ready for a
  2514. 2:55:50confrontation.
  2515. 2:55:56And there the Kvinga pride finds a lone
  2516. 2:56:00buffalo.
  2517. 2:56:08Local people have a name for these old
  2518. 2:56:11solitary bulls. Digger boys.
  2519. 2:56:21No buffalo is born alone. They grow up
  2520. 2:56:24in herds of hundreds, sometimes
  2521. 2:56:27thousands, sheltered by numbers their
  2522. 2:56:31whole lives.
  2523. 2:56:40>> [music]
  2524. 2:56:44>> But time spares no one as a ball ages,
  2525. 2:56:50slows,
  2526. 2:56:58falls out of step with the herd's
  2527. 2:57:00rhythm. He is left further and further
  2528. 2:57:04[music] behind.
  2529. 2:57:08until one day he wakes and finds himself
  2530. 2:57:12alone on the plains.
  2531. 2:57:16That is the fate of El Verano,
  2532. 2:57:21an old warrior cut off from the herd.
  2533. 2:57:27One more kick
  2534. 2:57:30could end her hunting life for good.
  2535. 2:57:46The Kvinga pride pulls out, leaving
  2536. 2:57:50behind a meal that should have been
  2537. 2:57:53served.
  2538. 2:57:55[music]
  2539. 2:58:00Between raw power and experience,
  2540. 2:58:05which one do you think decides who
  2541. 2:58:08survives?
  2542. 2:58:15Ela Terrano is left standing alone in
  2543. 2:58:19the dry riverbed.
  2544. 2:58:25A fight with the shape of faith in it.
  2545. 2:58:28David against Goliath, where one old
  2546. 2:58:32soldier refuses to bow before an
  2547. 2:58:34overwhelming crown.
  2548. 2:58:43Sappy leads her pride away. Tonight the
  2549. 2:58:47cavinda will sleep hungry.
  2550. 2:58:51That hunger will push them further
  2551. 2:58:54tomorrow into other country after other
  2552. 2:58:57prey.
  2553. 2:59:04[music]
  2554. 2:59:13Then one afternoon the sky changes
  2555. 2:59:17color.
  2556. 2:59:23>> [music]
  2557. 2:59:24>> The first rain of the season falls.
  2558. 2:59:28Cracked ground drinks every drop. And
  2559. 2:59:32[music] the dry season,
  2560. 2:59:34the season that squeezed them all,
  2561. 2:59:37finally loosens its hold. [music]
  2562. 2:59:43This is the opposite of the night we
  2563. 2:59:46began with. Now the water is back and
  2564. 2:59:50the [music] savannah starts to heal.
  2565. 2:59:54This is the eternal pulse of the
  2566. 2:59:57savannah.
  2567. 2:59:58Drought then rain, scarcity then plenty,
  2568. 3:00:04death then birth.
  2569. 3:00:14Every dry season is an examination
  2570. 3:00:18sorting out who is strong enough to
  2571. 3:00:20reach the next rains.
  2572. 3:00:29So who is truly the strongest on these
  2573. 3:00:34planes?
  2574. 3:00:40The one who hunts
  2575. 3:00:43or the one who survives.
  2576. 3:00:47Five different species,
  2577. 3:00:50five different situations.
  2578. 3:01:03But all of them share one thing. Not
  2579. 3:01:06[clears throat] one of them has fangs.
  2580. 3:01:09Not one of them.
  2581. 3:01:13All they have is legs.
  2582. 3:01:18[clears throat]
  2583. 3:01:21And those legs rewrote the rules.
  2584. 3:01:26Sometimes the strongest is simply the
  2585. 3:01:30one who dares to stand when every
  2586. 3:01:34instinct says run.
  2587. 3:01:40As for Sappi and her cave pride, the
  2588. 3:01:45journey goes on.
  2589. 3:01:52The rains give them another chapter to
  2590. 3:01:55live. Because on these planes, Hunter
  2591. 3:01:59and Hunted
  2592. 3:02:03are both trying to do the same thing.
  2593. 3:02:09Survive one more season. What do you
  2594. 3:02:13think? Who really owns the savannah?
  2595. 3:02:19The one who hunts
  2596. 3:02:21or the one who survives? Leave your
  2597. 3:02:24answer in the comments. The next
  2598. 3:02:27survival stories are waiting.
  2599. 3:02:32Three moments, three different ways to
  2600. 3:02:36survive.
  2601. 3:02:39One a personal sacrifice.
  2602. 3:02:42One a cooperation within a simil
  2603. 3:02:45species.
  2604. 3:02:48and one a coexistence between two
  2605. 3:02:51supreme predators.
  2606. 3:02:56The Serengeti and the Messiah Mara do
  2607. 3:03:00not reward the strongest.
  2608. 3:03:05They reward the one that chooses the
  2609. 3:03:08right strategy at the right moment.
  2610. 3:03:15Next season's migration, that same rule
  2611. 3:03:19will return. And no one.
  2612. 3:03:32Not even those who know this land best
  2613. 3:03:35can know the ending in advance.
  2614. 3:03:43No species here exists apart from the
  2615. 3:03:47rest.
  2616. 3:03:55The strongest today may be another's
  2617. 3:03:59meal tomorrow.
  2618. 3:04:05And it is that very loop that keeps this
  2619. 3:04:08whole land alive.
  2620. 3:04:15And perhaps that is the greatest lesson
  2621. 3:04:19of the whole migration.
  2622. 3:04:27Survival is not winning forever, but
  2623. 3:04:31winning long enough to earn one more
  2624. 3:04:35chance.
  2625. 3:04:39Uganda,
  2626. 3:04:41the primate capital of the planet with
  2627. 3:04:44more than 20 species
  2628. 3:04:47on an area the size of a midsized
  2629. 3:04:49American state.
  2630. 3:04:5240 million years of evolution have piled
  2631. 3:04:55up in one place.
  2632. 3:04:57Zuka, a 54 kg male olive baboon,
  2633. 3:05:03is about to do what no one has ever
  2634. 3:05:05seen.
  2635. 3:05:07And Tamu, a lioness, has just found the
  2636. 3:05:11edge that all but guarantees her the
  2637. 3:05:14win.
  2638. 3:05:24Queen Elizabeth National Park
  2639. 3:05:28stretches 1,978
  2640. 3:05:33square kilm [music]
  2641. 3:05:35along Uganda's western border.
  2642. 3:05:38But size is not what makes this [music]
  2643. 3:05:40place unusual.
  2644. 3:05:43Nowhere else in Africa
  2645. 3:05:48do four distinct ecosystems meet within
  2646. 3:05:52a single boundary.
  2647. 3:06:05Predators from each ecosystem push into
  2648. 3:06:07the next.
  2649. 3:06:10Prey must read danger signals from many
  2650. 3:06:12directions
  2651. 3:06:16and many kinds of threat at once.
  2652. 3:06:21The pressure in Queen Elizabeth National
  2653. 3:06:23Park
  2654. 3:06:25runs higher than anywhere else [music]
  2655. 3:06:26in Uganda
  2656. 3:06:29and it produces extraordinary
  2657. 3:06:31adaptations.
  2658. 3:06:34the Uganda [music] cobb, the antelope
  2659. 3:06:37native to this country,
  2660. 3:06:40and built a refined collective defense.
  2661. 3:06:46But the predators found the blind spot.
  2662. 3:06:51[music]
  2663. 3:06:54At Ishasha in the south of Queen
  2664. 3:06:56Elizabeth National Park,
  2665. 3:07:00a lion pride has rewritten the survival
  2666. 3:07:03equation for every species
  2667. 3:07:07within their range.
  2668. 3:07:10[music]
  2669. 3:07:12This is the world Zuka has to live in.
  2670. 3:07:20The spot Tamu chose is not a comfortable
  2671. 3:07:23one for a lion.
  2672. 3:07:26The candalabra tree carries toxic sap
  2673. 3:07:30and a spined trunk,
  2674. 3:07:33but its branches are strong enough to
  2675. 3:07:35hold a lion's solid body, and it grows
  2676. 3:07:38at a height where the preise warning
  2677. 3:07:40system stops working.
  2678. 3:07:46At 5 m up, the predator's scent is
  2679. 3:07:49carried off by the wind.
  2680. 3:07:57[music] The cob herd below the tree is
  2681. 3:07:59completely blind.
  2682. 3:08:23Luckily, other sharp senses let the cob
  2683. 3:08:26react in time.
  2684. 3:08:29As for the lion, this new hunting method
  2685. 3:08:31[music] may not be for them.
  2686. 3:08:44The olive baboon has one of the most
  2687. 3:08:46complex alarm call systems
  2688. 3:08:49in the primate order. Each predator
  2689. 3:08:53triggers a distinct response.
  2690. 3:08:56An eagle, a leopard,
  2691. 3:08:59but tree climbing lions are not in that
  2692. 3:09:03catalog.
  2693. 3:09:05The Ishasha pride has worked this
  2694. 3:09:07advantage for a long time.
  2695. 3:09:10Some troops have started changing their
  2696. 3:09:12protocol.
  2697. 3:09:18They move in sync in numbers large
  2698. 3:09:21enough
  2699. 3:09:22to break the ambush advantage of a
  2700. 3:09:25predator overhead.
  2701. 3:09:28Even so, this only cuts the losses.
  2702. 3:09:32It does not reverse the equation.
  2703. 3:09:37Most of the troop watches to avoid.
  2704. 3:09:41Zuka watched and he understands the
  2705. 3:09:44lions of this land. Tamu is no anonymous
  2706. 3:09:48lion
  2707. 3:09:50and Zuka will push that learning
  2708. 3:09:52further.
  2709. 3:09:53The goal is to flip the situation.
  2710. 3:10:02Queen Elizabeth National Park is the
  2711. 3:10:05crossroads of every direction of danger.
  2712. 3:10:07But Uganda is more than this one
  2713. 3:10:10national park. Across less than 400
  2714. 3:10:13kilometers, running west to east, Uganda
  2715. 3:10:18holds more primate species than any
  2716. 3:10:20country
  2717. 3:10:21on the African continent.
  2718. 3:10:29>> [music]
  2719. 3:10:35[music]
  2720. 3:10:38>> More than 20 species,
  2721. 3:10:42from the mountain gorilla
  2722. 3:10:45to nocturnal primates
  2723. 3:10:47most people have never heard of, have
  2724. 3:10:50settled at a single geographic point.
  2725. 3:10:53Windy, impenetrable forest is the first
  2726. 3:10:55direction.
  2727. 3:10:57310 square kilmters of forest in
  2728. 3:11:00southwestern Uganda
  2729. 3:11:03hold more than 459 mountain gorillas.
  2730. 3:11:07Roughly half the entire population of
  2731. 3:11:09the species on the planet.
  2732. 3:11:12Bundi is dense enough, steep enough, and
  2733. 3:11:16remote enough that no commercial hunter
  2734. 3:11:19can reach it.
  2735. 3:11:27Mountain gorillas share more than 98% of
  2736. 3:11:30their DNA with humans. This animal shows
  2737. 3:11:34social cognition.
  2738. 3:11:36once thought to be uniquely human,
  2739. 3:11:40such as individual recognition
  2740. 3:11:43or social power structures.
  2741. 3:11:46Built on the history of relationships
  2742. 3:11:49between individuals,
  2743. 3:11:51a silverback eats more than 30 kg of
  2744. 3:11:54plants a day, a female more than 18. To
  2745. 3:11:59meet that demand without stripping any
  2746. 3:12:01one area bare,
  2747. 3:12:04the silverback keeps a mental [music]
  2748. 3:12:06map of the environment updated
  2749. 3:12:08constantly
  2750. 3:12:10by season,
  2751. 3:12:13by the state of the plants, and by the
  2752. 3:12:16makeup of the group moving with him.
  2753. 3:12:20Gorillas climb trees for fruit up to 30
  2754. 3:12:23m high when ground sources run out with
  2755. 3:12:26the season.
  2756. 3:12:28This is the same vertical axis the
  2757. 3:12:30Ishasha lions exploit, but in the exact
  2758. 3:12:33opposite direction.
  2759. 3:12:35The lion climbs up to attack down. The
  2760. 3:12:39gorilla climbs up to find more.
  2761. 3:12:44The vertical axis in Uganda is not just
  2762. 3:12:47geography.
  2763. 3:12:48It is a survival script that every large
  2764. 3:12:52species must answer in its own way.
  2765. 3:12:58In Kibble forest about 200 km northeast
  2766. 3:13:02of Bindi,
  2767. 3:13:05evolution found
  2768. 3:13:07a completely different answer.
  2769. 3:13:17The chimpanzee bets on the social
  2770. 3:13:20network.
  2771. 3:13:23The kibble chimpanzee population has
  2772. 3:13:26grown from 3,300
  2773. 3:13:29in 1,997
  2774. 3:13:34to more than 5,000 today.
  2775. 3:13:38This is one of the few recorded cases of
  2776. 3:13:41a recovering primate population this
  2777. 3:13:44century.
  2778. 3:13:46That recovery came from reduced hunting
  2779. 3:13:48pressure and habitat restored year by
  2780. 3:13:52year.
  2781. 3:13:53Kibbal is a rare conservation signal,
  2782. 3:13:57a population that is rising [music]
  2783. 3:14:00rather than shrinking.
  2784. 3:14:05Male chimpanzees have been recorded
  2785. 3:14:08[singing and music] adopting
  2786. 3:14:09and caring for unrelated young,
  2787. 3:14:13a behavior extremely rare among animals.
  2788. 3:14:17But within a chimpanzees long-term
  2789. 3:14:19social network, caring [music] for an
  2790. 3:14:22individual outside the bloodline is an
  2791. 3:14:25investment in social standing.
  2792. 3:14:28The chimpanzeee does not act on feeling
  2793. 3:14:30alone,
  2794. 3:14:32but on complex social calculation.
  2795. 3:14:36Chimpanzees organize hunts by assigned
  2796. 3:14:39roles,
  2797. 3:14:41including individuals who block the
  2798. 3:14:43escape, who chase, and who ambush.
  2799. 3:14:47That group coordination has been studied
  2800. 3:14:49for decades and keeps producing new
  2801. 3:14:52evidence of the species collective
  2802. 3:14:55planning.
  2803. 3:14:59The gorilla bets on size, the
  2804. 3:15:01chimpanzees, and attack vantage point.
  2805. 3:15:05The baboons do not just lose a familiar
  2806. 3:15:08food source.
  2807. 3:15:11They lose a safe reference point in the
  2808. 3:15:13survival map
  2809. 3:15:15coded over generations and it turns into
  2810. 3:15:18a source of danger. The troops reflexes
  2811. 3:15:22have no fitting answer for.
  2812. 3:15:29[music]
  2813. 3:15:30Uganda has more than 1,000 bird species,
  2814. 3:15:34the highest [music] density of bird
  2815. 3:15:36diversity
  2816. 3:15:38in Africa by area.
  2817. 3:15:42The shoe bill hunts the papyrus swamps
  2818. 3:15:45of Uganda.
  2819. 3:15:47Its strategy is absolute stillness.
  2820. 3:15:55The African fish eagle at the Kazinga
  2821. 3:15:57channel works the vertical axis in the
  2822. 3:16:01opposite direction.
  2823. 3:16:04What makes the fish eagle effective is
  2824. 3:16:07its map of the water. Where prey gathers
  2825. 3:16:11by season,
  2826. 3:16:13where it gathers by the hour,
  2827. 3:16:17where it gathers as temperature and
  2828. 3:16:19current shift. The fish eagle and the
  2829. 3:16:22shoe bill both use patience,
  2830. 3:16:25but through two completely different
  2831. 3:16:27designs.
  2832. 3:16:34The gray crowned crane appears on
  2833. 3:16:37Uganda's national flag
  2834. 3:16:40and on the grasslands of Queen Elizabeth
  2835. 3:16:43National Park [music] every morning. The
  2836. 3:16:46bird a nation chooses for its flag
  2837. 3:16:50often reflects something [music] about
  2838. 3:16:52how that nation understands itself.
  2839. 3:16:56Uganda chose the crowned crane because
  2840. 3:16:58it lives in every kind of terrain.
  2841. 3:17:03Uganda holds savannah, forest border,
  2842. 3:17:06grassland, riverbank,
  2843. 3:17:09and because it's calm in all conditions
  2844. 3:17:14is the image Ugandans want tied to their
  2845. 3:17:16[music] identity.
  2846. 3:17:19The diversity of Uganda's primates
  2847. 3:17:21[music]
  2848. 3:17:22is proof of the many different ways to
  2849. 3:17:24adapt to nature.
  2850. 3:17:27When the environment is pushed to its
  2851. 3:17:29limit, where dry cliffs replace dense
  2852. 3:17:32forest
  2853. 3:17:34and resources become scarce.
  2854. 3:17:36The mantle baboon has raised the idea of
  2855. 3:17:39alliance into the ultimate survival
  2856. 3:17:42strategy.
  2857. 3:17:44Assimulation.
  2858. 3:17:51A dog's imprinting window lasts 6 weeks
  2859. 3:17:54after birth.
  2860. 3:17:56During that window, the puppy's brain is
  2861. 3:18:00building its map of species recognition.
  2862. 3:18:03After 6 weeks,
  2863. 3:18:05that map closes for good.
  2864. 3:18:09The baboon is not choosing at random.
  2865. 3:18:12They know that window exists.
  2866. 3:18:18[music]
  2867. 3:18:29Behaviorally, the puppy treats the
  2868. 3:18:31baboon troop as its own social unit.
  2869. 3:18:35Its brain learned this during the
  2870. 3:18:37imprinting window. That social anchor
  2871. 3:18:40once it is set cannot be erased later.
  2872. 3:18:44In the language of primate behavior,
  2873. 3:18:48grooming between two individuals is a
  2874. 3:18:50signal of social alliance. This is a
  2875. 3:18:54transaction. The dog sense of smell
  2876. 3:18:57beats the baboons
  2877. 3:18:59in low light and on terrain where scent
  2878. 3:19:02carries before sound arrives.
  2879. 3:19:05The sensory systems of both species
  2880. 3:19:08combine into a danger detection network
  2881. 3:19:12that reaches far beyond what either
  2882. 3:19:14species has alone.
  2883. 3:19:17The domestic dog, once potential prey
  2884. 3:19:20for wild dogs, becomes an individual
  2885. 3:19:24protected by a primate troop.
  2886. 3:19:27The baboon actively creates the
  2887. 3:19:30conditions for this relationship to
  2888. 3:19:31exist by choosing the right partner, the
  2889. 3:19:35right biological window, the right
  2890. 3:19:38method of integration. Similar behavior
  2891. 3:19:42has been recorded in many baboon and
  2892. 3:19:45other primate populations across the
  2893. 3:19:47continent.
  2894. 3:19:49This is evidence of a level of social
  2895. 3:19:51cognition,
  2896. 3:19:54the ability to recognize a mutualism,
  2897. 3:19:58opportunity, and act on [music] it with
  2898. 3:20:00calculation. The baboon does not just
  2899. 3:20:03take part in the transaction.
  2900. 3:20:06This primate seeks it out actively and
  2901. 3:20:09accumulates those transactions
  2902. 3:20:11systematically.
  2903. 3:20:13The baboon has to assess each specific
  2904. 3:20:16dog,
  2905. 3:20:18each specific imprinting window, each
  2906. 3:20:22specific context to decide whether that
  2907. 3:20:26transaction is worth making. The
  2908. 3:20:28alliance is not only between baboon and
  2909. 3:20:30dog. Alliance is the operating principle
  2910. 3:20:35of the entire wild survival system. And
  2911. 3:20:38the baboon will apply that principle in
  2912. 3:20:41the next step.
  2913. 3:20:48The danger in Queen Elizabeth National
  2914. 3:20:50Park does not fall. It changes species.
  2915. 3:20:55The leopard is the only animal in this
  2916. 3:20:57ecosystem
  2917. 3:20:59that uses trees both ways. Up to hide,
  2918. 3:21:04down to attack, and works in light too
  2919. 3:21:07low.
  2920. 3:21:09for most prey to process visual
  2921. 3:21:11information
  2922. 3:21:13as fast as they do by day.
  2923. 3:21:16The leopard's speed, the leopard's
  2924. 3:21:18climbing ability,
  2925. 3:21:20and the leopard's [music] timing all at
  2926. 3:21:22once create a set of advantages.
  2927. 3:21:26No prey species has a complete answer
  2928. 3:21:29for the lion and the leopard both use
  2929. 3:21:32trees as an edge, but on two completely
  2930. 3:21:35[music] different logics.
  2931. 3:21:37The lion uses the tree as a vantage
  2932. 3:21:40point, climbing up to watch. Climbing up
  2933. 3:21:43to erase the chance of being caught by
  2934. 3:21:45[music] scent. The leopard uses the tree
  2935. 3:21:48as a hide point,
  2936. 3:21:51lying on a branch [music] quiet enough
  2937. 3:21:54that prey passes below without knowing.
  2938. 3:21:57The lion attacks vertically from above.
  2939. 3:22:01The leopard attacks horizontally
  2940. 3:22:04from a hidden position. Two tree
  2941. 3:22:06climbing strategies are two kinds of
  2942. 3:22:09danger that cannot be [music] solved by
  2943. 3:22:12the same reflex. The olive baboon has
  2944. 3:22:15alarm calls that tell leopard and lion
  2945. 3:22:17apart. But an alarm call for a leopard
  2946. 3:22:21at night
  2947. 3:22:23requires the troop to detect the leopard
  2948. 3:22:25first. And a leopard at night is fully
  2949. 3:22:28optimized
  2950. 3:22:29for not being seen before it attacks. An
  2951. 3:22:33alarm call is only useful when there is
  2952. 3:22:36enough information to set it off.
  2953. 3:22:40At night, that gap is a [music] dead
  2954. 3:22:42gap. The olive baboon troop sleeps in
  2955. 3:22:45tall trees. To cut contact with ground
  2956. 3:22:49predators at night, the tree is tall
  2957. 3:22:52enough [music] that a leopard's climbing
  2958. 3:22:54speed cannot reach them before the alarm
  2959. 3:22:57goes off. Not a perfect solution, but
  2960. 3:23:01enough to survive. to the next morning.
  2961. 3:23:04Survival does not require perfection. It
  2962. 3:23:07requires being good enough to get
  2963. 3:23:09through one more night.
  2964. 3:23:15Daylight gives the light back. Safety
  2965. 3:23:19does not come back with it. The African
  2966. 3:23:22crowned eagle
  2967. 3:23:24specializes in attacking small primates
  2968. 3:23:27and the young. The crowned eagle's grip
  2969. 3:23:30force concentrates
  2970. 3:23:32in talons strong enough to cause serious
  2971. 3:23:35injury
  2972. 3:23:37to a small primate in a single contact.
  2973. 3:23:41This is a threat from the air that
  2974. 3:23:44neither leopard nor lion can reproduce
  2975. 3:23:48and that no ground reflex can [music]
  2976. 3:23:50solve.
  2977. 3:23:52The baboon's alarm call for an eagle
  2978. 3:23:56pulls the troop down into low brush.
  2979. 3:23:59The alarm call for a lion in a tree
  2980. 3:24:02scatters the troop across the ground.
  2981. 3:24:05Those two responses contradict each
  2982. 3:24:07other. A predator smart enough will know
  2983. 3:24:10how to exploit that contradiction.
  2984. 3:24:13For prey at Queen Elizabeth National
  2985. 3:24:16Park, every direction is a potential
  2986. 3:24:19direction of danger. Within that
  2987. 3:24:22four-way pressure system, no position is
  2988. 3:24:25completely safe. Every decision to move,
  2989. 3:24:29every sleeping spot, every foraging
  2990. 3:24:32route is a trade-off, between kinds of
  2991. 3:24:35danger.
  2992. 3:24:37That pressure does not only drive
  2993. 3:24:39individual adaptation,
  2994. 3:24:42it drives social adaptation between
  2995. 3:24:44species.
  2996. 3:24:46This is not a fixed environment.
  2997. 3:24:49This is an environment complex enough to
  2998. 3:24:53push species to seek [music] solutions.
  2999. 3:24:56No single species could find alone.
  3000. 3:25:00Uganda does not reward the strongest. It
  3001. 3:25:03rewards the one that reads the
  3002. 3:25:05environment most accurately.
  3003. 3:25:08The gorilla reads the terrain and
  3004. 3:25:10chooses the fortress. The chimpanzee
  3005. 3:25:13reads the social structure and chooses
  3006. 3:25:16the network. The baboon reads the
  3007. 3:25:19mutualism opportunity [music] and builds
  3008. 3:25:21an alliance no one imagined. The shoe
  3009. 3:25:24bill reads the water by the hour.
  3010. 3:25:28The fish eagle reads the vertical axis
  3011. 3:25:31in the direction opposite the lion and
  3012. 3:25:35the pressure from four directions does
  3013. 3:25:36not fall. It accumulates by the year by
  3014. 3:25:40the generation.
  3015. 3:25:42There is one more thing Zuka has not
  3016. 3:25:44tried.
  3017. 3:25:45Zuka is about to try it. It will be the
  3018. 3:25:49thing no scientist
  3019. 3:25:51believed could happen before it
  3020. 3:25:53happened. Not because it is beyond the
  3021. 3:25:56baboon's physical ability, but because
  3022. 3:25:59to do it, the baboon has to read. A gap
  3023. 3:26:05that the species entire
  3024. 3:26:07evolutionary system was never asked to
  3025. 3:26:10find. A gap in the armor of the top of
  3026. 3:26:13the food chain.
  3027. 3:26:15Not a physical gap, not a speed gap,
  3028. 3:26:19a gap in the schedule. The specific
  3029. 3:26:22window when the strongest in the
  3030. 3:26:25ecosystem [music]
  3031. 3:26:26is not present on the terrain. The
  3032. 3:26:29baboon has learned over months of
  3033. 3:26:31watching. That gap has always been
  3034. 3:26:34there. It is only that no species was
  3035. 3:26:37ever prepared enough to see it and bold
  3036. 3:26:40enough in the cognitive sense to act in
  3037. 3:26:45the brief window. It opens. The last
  3038. 3:26:49light of day stretches the shadow of the
  3039. 3:26:52candalabra across the grassland.
  3040. 3:26:55In the next few minutes, everything will
  3041. 3:26:58change.
  3042. 3:27:00[music]
  3043. 3:27:03In the first 6 to 8 weeks of life, a
  3044. 3:27:07lion cub does not follow the pride when
  3045. 3:27:09the lioness goes to hunt.
  3046. 3:27:12Not by chance.
  3047. 3:27:14The male baboon has watched long enough
  3048. 3:27:17to know the lioness is not there.
  3049. 3:27:21The male baboon has gathered enough
  3050. 3:27:23information about a gap in the absolute
  3051. 3:27:27protection of a single mother.
  3052. 3:27:30An adult lioness has every physical
  3053. 3:27:33advantage
  3054. 3:27:35to decide the outcome against a male
  3055. 3:27:38olive baboon.
  3056. 3:27:45Speed, strength, and size all lean
  3057. 3:27:48toward the lion. In the tree, that
  3058. 3:27:52equation reverses completely. The baboon
  3059. 3:27:55is on home turf with reflexes and a limb
  3060. 3:27:59structure optimized
  3061. 3:28:01for the three dimensions of the canopy.
  3062. 3:28:04The lion cub is small, not heavy enough,
  3063. 3:28:08not skilled enough at climbing, not
  3064. 3:28:11strong enough to get itself out of that
  3065. 3:28:12terrain. In the language of primate
  3066. 3:28:15behavior,
  3067. 3:28:17holding without killing is dominance.
  3068. 3:28:21The baboon is controlling. The most
  3069. 3:28:24valuable resource of its rival.
  3070. 3:28:47Zuka controls the board.
  3071. 3:28:56Both Zuka and Tamu's cub survived that
  3072. 3:28:59day. The world goes on as if it had
  3073. 3:29:03known this all along.
  3074. 3:29:05This is not defensive behavior in the
  3075. 3:29:08ordinary sense. This is not territorial
  3076. 3:29:11behavior. This is a calculated
  3077. 3:29:14preemptive strategy based on predicting
  3078. 3:29:17another species behavior carried out on
  3079. 3:29:20terrain chosen on purpose. This is
  3080. 3:29:23evidence of situational intelligence,
  3081. 3:29:27the ability to read a specific situation
  3082. 3:29:30and act. A survival tool more effective
  3083. 3:29:33than any other.
  3084. 3:29:36And this is what Uganda gives to the
  3085. 3:29:38species that live long enough to learn
  3086. 3:29:40it. Zuka returns to the troop. There is
  3087. 3:29:44no celebration. The troop keeps to the
  3088. 3:29:47morning's foraging route as if nothing
  3089. 3:29:50had happened. Because by the species
  3090. 3:29:54survival logic, nothing really did
  3091. 3:29:57happen except a decision that led to an
  3092. 3:30:02outcome and life continues from that
  3093. 3:30:05outcome. This is the most defining trait
  3094. 3:30:08of real survival intelligence. There is
  3095. 3:30:11no celebration. There is only the next
  3096. 3:30:14step.
  3097. 3:30:16Zuka sits on the outer edge of the
  3098. 3:30:18troop.
  3099. 3:30:20The spot with the longest view. That
  3100. 3:30:23spot does not change. It does not mean
  3101. 3:30:26nothing changed. The events of that
  3102. 3:30:28morning were integrated
  3103. 3:30:31into the store of behavioral data Zuka
  3104. 3:30:35has built over months. That store took
  3105. 3:30:38on one more point about the systems
  3106. 3:30:40capability, one point about the rivals
  3107. 3:30:42reaction and one point about the gap in
  3108. 3:30:46the armor of the one with superior size
  3109. 3:30:49and strength. The olive baboon takes no
  3110. 3:30:52notes.
  3111. 3:30:54The olive baboon does not talk.
  3112. 3:30:57But the olive baboon remembers and that
  3113. 3:31:00memory carries weight in every decision
  3114. 3:31:03that follows.
  3115. 3:31:05There is no crown to win in this
  3116. 3:31:07ecosystem.
  3117. 3:31:09Zuka [music] proved one thing that here
  3118. 3:31:12intelligence has real measurable value.
  3119. 3:31:16That value does not come from size or
  3120. 3:31:19speed. It comes from reading the
  3121. 3:31:22specific environment accurately enough
  3122. 3:31:25to act in the right window of time on
  3123. 3:31:28the right [music] terrain
  3124. 3:31:31with the right strategy. That is what
  3125. 3:31:33Uganda prepared Zuka for across a
  3126. 3:31:37lifetime by setting a test that only
  3127. 3:31:40intelligence can pass.
  3128. 3:31:42Among Kibble's 13 dal primate species
  3129. 3:31:46and among Uganda's more than 20 primate
  3130. 3:31:49species, no species is like another. No
  3131. 3:31:53strategy is like another. But all are
  3132. 3:31:56doing the same thing,
  3133. 3:31:59surviving in the best way they can.
  3134. 3:32:02With the tools evolution prepared for
  3135. 3:32:05them in an environment no one designed
  3136. 3:32:08for them, the olive baboon troop at
  3137. 3:32:10Queen Elizabeth's National Park
  3138. 3:32:13does not mark time by the year. Each day
  3139. 3:32:16is a set of new decisions,
  3140. 3:32:19including new foraging routes, new
  3141. 3:32:22sleeping spots. Reassessing the risk
  3142. 3:32:26from predators
  3143. 3:32:28and new individuals moving through the
  3144. 3:32:30territory. Accumulated knowledge is not
  3145. 3:32:33stored in language or symbol.
  3146. 3:32:36It is coded into behavior patterns
  3147. 3:32:39into reflexes tuned over many trials
  3148. 3:32:45into a body memory of the terrain and of
  3149. 3:32:48the behavior of specific individuals in
  3150. 3:32:51that environment.
  3151. 3:32:53The young baboons in the troop are
  3152. 3:32:55learning through observation, [music]
  3153. 3:32:58through following the older individuals,
  3154. 3:33:01through testing each small behavior in a
  3155. 3:33:03safe setting. This is how survival
  3156. 3:33:06intelligence is passed on. When an older
  3157. 3:33:09baboon dies, the troop loses more than
  3158. 3:33:12one individual.
  3159. 3:33:14It loses a living library of that
  3160. 3:33:17environment. But that does not stop the
  3161. 3:33:20troop from continuing to learn.
  3162. 3:33:22Queen Elizabeth National Park wakes at
  3163. 3:33:25dawn. Every species is doing the same
  3164. 3:33:28first act of the day, connecting with
  3165. 3:33:31its group. The gorilla silverback at
  3166. 3:33:35Wendy begins the day with grooming
  3167. 3:33:38inside the group. Grooming is not a
  3168. 3:33:41ritual. It is the maintenance protocol
  3169. 3:33:44for the social network.
  3170. 3:33:47In a group where every individual
  3171. 3:33:49depends on every other to survive,
  3172. 3:33:52keeping that thread of connection
  3173. 3:33:53matters more than anything that could be
  3174. 3:33:56filled by food. A 220 [music]
  3175. 3:34:00kilogram silverback with muscle mass
  3176. 3:34:03enough to change the outcome of nearly
  3177. 3:34:06any physical conflict in the ecosystem
  3178. 3:34:09begins the day with silence.
  3179. 3:34:12This is peace.
  3180. 3:34:14At Kibal, the young chimpanzees are
  3181. 3:34:17playing.
  3182. 3:34:19Every fall, every gentle wrestle,
  3183. 3:34:22every climb and drop [music] back down
  3184. 3:34:26is a lesson. Empathy is not uniquely
  3185. 3:34:29human.
  3186. 3:34:30The male chimpanzee adopting a single
  3187. 3:34:33parent young proved that with specific
  3188. 3:34:36observational data, the young
  3189. 3:34:39chimpanzees playing together are
  3190. 3:34:41learning it every day from the body's
  3191. 3:34:44reaction to touching another body, from
  3192. 3:34:47the feel of the social thread, as it is
  3193. 3:34:50made and as it breaks.
  3194. 3:34:52The African fish eagle at the Kazinga
  3195. 3:34:55channel stands on its familiar spot. A
  3196. 3:34:58wateride branch used long enough that
  3197. 3:35:01the talon marks are pressed into the
  3198. 3:35:04bark. The predator repeats because that
  3199. 3:35:07spot has been confirmed as optimal for
  3200. 3:35:11the purpose of hunting. Tens of
  3201. 3:35:13thousands of Uganda cobb move across the
  3202. 3:35:16grassland
  3203. 3:35:18north of Queen Elizabeth National Park
  3204. 3:35:20along the same route. The herd has
  3205. 3:35:23traveled for generations.
  3206. 3:35:26The cob move together, ears up, eyes
  3207. 3:35:30scanning, the sensory system running at
  3208. 3:35:33a constant baseline.
  3209. 3:35:35Tamu lies on the candalabra branch, an
  3210. 3:35:39ordinary morning like any other.
  3211. 3:35:42Tamu keeps nothing special from that
  3212. 3:35:44morning.
  3213. 3:35:46The order of the pride does not change.
  3214. 3:35:51Life goes on. It does not mean Tamu
  3215. 3:35:53lost.
  3216. 3:35:55It means Tamu is doing exactly what
  3217. 3:35:58evolution prepared her for. And what
  3218. 3:36:01evolution prepared for Tamu is enough to
  3219. 3:36:04survive in most situations. But most is
  3220. 3:36:07not all. In the western lands of Uganda,
  3221. 3:36:11female elephants move along a route that
  3222. 3:36:14is both hope and responsibility.
  3223. 3:36:17In 1980, the elephant population at
  3224. 3:36:20Queen Elizabeth National Park was nearly
  3225. 3:36:22wiped out. War and large-scale poaching
  3226. 3:36:26drove the numbers down to a level. Many
  3227. 3:36:29ecologists called [music] the point of
  3228. 3:36:31no return. The ecosystem cannot run
  3229. 3:36:35right without elephants, [music] and the
  3230. 3:36:37elephants could not recover alone.
  3231. 3:36:40Today, about 5,000 elephants live in
  3232. 3:36:43Uganda.
  3233. 3:36:44That population recovered thanks to a
  3234. 3:36:46human decision to protect it and let
  3235. 3:36:49nature do the rest. 40 years.
  3236. 3:36:53A part of one human lifetime. Enough
  3237. 3:36:56time for a species near extinction.
  3238. 3:37:00To recover to ecological function, an
  3239. 3:37:03ecosystem can recover.
  3240. 3:37:06If humans let it recover, the baboon's
  3241. 3:37:09enemy is not the lion. The baboon's
  3242. 3:37:12enemy is a strand of snare wire. It is
  3243. 3:37:16the cleared field. It is the new road
  3244. 3:37:18cut across the territory. The troop has
  3245. 3:37:21used for generations under the constant
  3246. 3:37:24pressure bearing down on the environment
  3247. 3:37:26and the animals. [music]
  3248. 3:37:28Conservation decisions have to be made
  3249. 3:37:31without pause. This is the greatest
  3250. 3:37:34battle in Uganda.
  3251. 3:37:36Humans are the variable that decides the
  3252. 3:37:38outcome. Ecoourism in Uganda brings in
  3253. 3:37:42revenue every year. About 80% of that
  3254. 3:37:46revenue [music]
  3255. 3:37:46is tied directly to the protected areas,
  3256. 3:37:50including the Bindy Forest with its
  3257. 3:37:53gorillas. The olive baboon proved this.
  3258. 3:37:56Among Uganda's more than 20 primate
  3259. 3:37:58species, no species is like another. The
  3260. 3:38:01gorilla chooses strength and
  3261. 3:38:03impenetrable terrain.
  3262. 3:38:07The chimpanzee chooses the social
  3263. 3:38:09network and group size. The olive baboon
  3264. 3:38:13chooses flexibility and mutualism and
  3265. 3:38:15situational intelligence.
  3266. 3:38:18But all are doing the same thing,
  3267. 3:38:21surviving in the best way they can with
  3268. 3:38:24the tools evolution prepared for them in
  3269. 3:38:28an environment no one designed for any
  3270. 3:38:31species.
  3271. 3:38:33And all those answers from the simplest
  3272. 3:38:36to the most complex deserve to exist.
  3273. 3:38:40This is the image that begins this
  3274. 3:38:42story. And this is also the image that
  3275. 3:38:45ends it.
  3276. 3:38:47Tomorrow morning, Tamu will be on that
  3277. 3:38:49branch again. The baboon troop will move
  3278. 3:38:52through that area again. Uh
  3279. 3:38:57where intelligence chose not to run.
  3280. 3:39:02No one is born a legend. A legend is
  3281. 3:39:05forged only in battle. Every scar
  3282. 3:39:08carries a price paid, and only the
  3283. 3:39:11strongest are remembered. Sunlight pours
  3284. 3:39:14down on the Serengeti,
  3285. 3:39:17like molten copper spilling across the
  3286. 3:39:19plane. There is only the heavy heat
  3287. 3:39:22shimmering off the ground in waves,
  3288. 3:39:25invisible, and then a roar rips the
  3289. 3:39:28silence apart. That roar carries nearly
  3290. 3:39:315 miles about 8 km across the savannah
  3291. 3:39:36[music] echoing back from distant acacia
  3292. 3:39:39stands trembling on the horizon. The
  3293. 3:39:42male lion who rules here with a man like
  3294. 3:39:45a crown thick and dark.
  3295. 3:39:49The unmistakable sign of surging
  3296. 3:39:52testosterone and countless life or death
  3297. 3:39:55battles survived has held this pride for
  3298. 3:39:59more than 2 years. Yet
  3299. 3:40:03the average reign of a male lion lasts
  3300. 3:40:06only 2 to 3 years. The challenger is a
  3301. 3:40:09coalition of nomadic male lions. They
  3302. 3:40:12are younger, hungrier, and far more
  3303. 3:40:15reckless. Each [music] weighs more than
  3304. 3:40:18180 kg.
  3305. 3:40:20Muscles rippling beneath tanned hide,
  3306. 3:40:22darkened by years of rain [music] and
  3307. 3:40:25sun. They close the distance
  3308. 3:40:28under the [music] scorching midday heat.
  3309. 3:40:31Every step is slow and calculated, as if
  3310. 3:40:34counting down to the inevitable.
  3311. 3:40:37In the kingdom of the Serengeti, power
  3312. 3:40:40is taken by muscle,
  3313. 3:40:43by fang, by claw, and by blood.
  3314. 3:40:47Far off below a dense stand of acacia.
  3315. 3:40:52A shape slips through the [music] tall
  3316. 3:40:53grass without a sound. This is the
  3317. 3:40:56leopard, the most solitary hunter on the
  3318. 3:41:00Serengeti [music] plane. Its spotted
  3319. 3:41:02coat blends perfectly [music] into the
  3320. 3:41:06interplay of sun and shade. Filtered
  3321. 3:41:09through the canopy above, the [music]
  3322. 3:41:11leopard bolts forward, accelerating up
  3323. 3:41:14to 58 km hour [music] in a burst that
  3324. 3:41:19blurs the eye. Its jaws lock onto the
  3325. 3:41:22prey with a [music] bite of about 300 lb
  3326. 3:41:25per square in.
  3327. 3:41:28Smaller than a lion's, but precise
  3328. 3:41:30enough to end everything in an instant.
  3329. 3:41:33Yet on the Serengeti, [music] bringing
  3330. 3:41:35down the prey is only half the battle.
  3331. 3:41:39The smell of fresh blood spreads fast
  3332. 3:41:42across the open grassland,
  3333. 3:41:44and the lion is never far away. A male
  3334. 3:41:48lion
  3335. 3:41:50appears from behind the stand of trees,
  3336. 3:41:53moving in with heavy, menacing steps.
  3337. 3:41:57The leopard does not choose to fight. It
  3338. 3:41:59knows its own weight.
  3339. 3:42:02Is [music] not even half its rivals.
  3340. 3:42:04Instead, it does something
  3341. 3:42:06extraordinary. Clamping its jaws
  3342. 3:42:10around a carcass nearly twice its own
  3343. 3:42:12body weight
  3344. 3:42:14and hauling it up into the sky high into
  3345. 3:42:18a tall tree. The male lion stands below,
  3346. 3:42:22lifting its eyes but cannot follow. This
  3347. 3:42:25is the leopard's strategy.
  3348. 3:42:28When you cannot win by strength, you win
  3349. 3:42:31by cunning and [music] by agility. But
  3350. 3:42:34there is another power on the Serengeti
  3351. 3:42:36plane. Not as strong as the lion.
  3352. 3:42:40Not as fast as the leopard, but smarter
  3353. 3:42:43than both of them. The spotted hyena.
  3354. 3:42:47[music] The most misunderstood carnivore
  3355. 3:42:49in Africa. Most people assume
  3356. 3:42:53they are only scavengers feeding off the
  3357. 3:42:56spoils of other species. The truth
  3358. 3:43:01is far more astonishing. Hyenas [music]
  3359. 3:43:03are extremely effective hunters and they
  3360. 3:43:06hold the most complex social structure.
  3361. 3:43:10Among land mammals, their jaws produce
  3362. 3:43:13the strongest bite force. among land
  3363. 3:43:16carnivores,
  3364. 3:43:18enough to crush a femur. But the hyena's
  3365. 3:43:21most [music] fearsome weapon is not in
  3366. 3:43:23its jaws. It is in its brain. Hyenas
  3367. 3:43:27live in fish fusion societies, groups
  3368. 3:43:31that constantly split.
  3369. 3:43:34And
  3370. 3:43:35we walked through the rurest moments of
  3371. 3:43:38raising young in the wild in the
  3372. 3:43:41Okavango Delta.
  3373. 3:43:45Which animal today changed how you see
  3374. 3:43:49the wild world?
  3375. 3:43:51Was it the mother buffalo protecting her
  3376. 3:43:55calf
  3377. 3:43:57or the hunting lesson the mother lion
  3378. 3:44:00taught her cubs?
