00:17:59,840 --> 00:18:03,280 Unfortunately, it means leaving their chicks alone. 226 00:18:04,960 --> 00:18:07,640 Predators have waited for this moment. 227 00:18:07,640 --> 00:18:10,960 THEY SQUAWK

they have a few surprises in store. 231 00:18:41,040 --> 00:18:44,120 Their final deterrent is truly repulsive. 232 00:18:53,000 --> 00:18:55,400 Gull's can't risk clogging their feathers. 233 00:18:55,400 --> 00:18:57,640 It seeks a more wholesome meal. 234 00:19:03,960 --> 00:19:05,800 At the Rockhopper colony, 235 00:19:05,800 --> 00:19:07,200 it's time for a change of shifts. 236 00:19:09,400 --> 00:19:13,080 The Rockhopper fathers have been relieved of parenting duties. 237 00:19:13,080 --> 00:19:15,000 It's now their turn to go fishing. 238 00:19:24,000 --> 00:19:25,560 THEY

00:20:18,960 are made to be broken. 245 00:20:41,480 --> 00:20:43,280 They haven't been to sea for two weeks. 246 00:20:43,280 --> 00:20:46,480 They will soon be back in their element. 247

00:22:13,400 After three months on land, 254 00:22:13,400 --> 00:22:17,080 they will spend the next four weeks in the open ocean, 255 00:22:17,080 --> 00:22:19,880 chasing fish along the edge of the ice sheet. 256 00:22:21,120 --> 00:22:22,840 They're back in their natural home. 257 00:22:31,360 --> 00:22:33,560 Before the Humboldts can take their bath, 258 00:22:33,560 --> 00:22:35,560 they must cross a dangerous barrier. 259 00:22:35,560 --> 00:22:38,960 Sea lions block their route to the sea. 260 00:22:38,960 --> 00:22:41,440 SEA LIONS SNARL 261 00:22:43,120 --> 00:22:45,320 Descending the

00:23:08,520 Sea lions are deadly predators in the sea, 265 00:23:08,520 --> 00:23:11,320 but they're lazy and sleepy on land. 266 00:23:19,280 --> 00:23:20,920 It should be just a matter of 267 00:23:20,920 --> 00:23:22,120 not waking them up. 268 00:23:30,480 --> 00:23:32,520 The first finds a safe route. 269 00:23:32,520 --> 00:23:34,640 The rest sneak up behind. 270 00:23:41,360 --> 00:23:45,760 They squeeze between the mass of slumbering blubber and the rocks. 271 00:23:52,360 --> 00:23:53,880 SEA LION BARKS 272 00:23:53,880 --> 00:23:55,320 They're spotted... 273 00:23:55,320 --> 00:23:56,840 SEA LIONS GROWL 274 00:24:03,520 --> 00:24:05,680 ..but they escape just in time. 275 00:24:07,680 --> 00:24:10,200 The penguins make a last dash to the sea. 276 00:24:18,360 --> 00:24:19,800 They need their bath. 277 00:24:19,800 --> 00:24:21,040 Their plumage must be 278 00:24:21,040 --> 00:24:23,040 in perfect condition for fishing. 279 00:24:28,560 --> 00:24:31,040 A new Humboldtcam arrives. 280 00:24:31,040 --> 00:24:32,880 It's a robotic submersible, 281 00:24:32,880 --> 00:24:34,440 with a camera in its eye. 282 00:24:38,560 --> 00:24:41,200 The shy penguins are relaxed in its presence 283 00:24:41,200 --> 00:24:43,280 and they can be filmed underwater 284 00:24:43,280 --> 00:24:45,360 for the first time. 285 00:24:54,680 --> 00:24:57,520 The sea around is overflowing with fish. 286 00:25:01,160 --> 00:25:04,000 The shoals thrive on the nutrients brought here 287 00:25:04,000 --> 00:25:06,280 by the Humboldt current. 288 00:25:06,280 --> 00:25:07,440 This cold upwelling 289 00:25:07,440 --> 00:25:09,360 allows these penguins to survive 290 00:25:09,360 --> 00:25:10,760 so close to the Equator. 291 00:25:19,000 --> 00:25:23,040 But the fish shoals attract more than just penguins. 292 00:25:23,040 --> 00:25:26,280 A fur seal surfaces near Humboldtcam. 293 00:25:27,480 --> 00:25:30,200 Unlike sea lions, they rarely kill penguins, 294 00:25:30,200 --> 00:25:31,360 but they do love 295 00:25:31,360 --> 00:25:32,960 chasing them for fun. 296 00:26:11,640 --> 00:26:13,400 If the penguins are to fish in peace, 297 00:26:13,400 --> 00:26:15,640 they must brave the open ocean. 298 00:26:24,720 --> 00:26:29,000 Back with the Emperors, the females are now firmly in charge. 299 00:26:29,000 --> 00:26:33,440 Their first big challenge arrives - an Antarctic blizzard. 300 00:26:37,320 --> 00:26:39,280 The penguins protect their chicks 301 00:26:39,280 --> 00:26:41,280 by turning their backs to the wind. 302 00:26:41,280 --> 00:26:43,160 THEY CHITTER 303 00:26:46,480 --> 00:26:48,720 But soon, it's not enough. 304 00:26:54,800 --> 00:26:58,600 The chicks are still exposed to the swirling winds. 305 00:26:58,600 --> 00:27:00,560 To survive the worsening weather, 306 00:27:00,560 --> 00:27:02,560 they must huddle closer together. 307 00:27:04,480 --> 00:27:07,080 They start to gather in even greater numbers. 308 00:27:16,840 --> 00:27:19,000 PENGUINS CHITTER 309 00:27:20,960 --> 00:27:22,560 A huge mass of penguins 310 00:27:22,560 --> 00:27:24,680 can share warmth and shelter. 311 00:27:26,960 --> 00:27:29,080 But the crush means it's a risky place 312 00:27:29,080 --> 00:27:30,400 for a young chick to be. 313 00:27:32,920 --> 00:27:36,160 At first, penguins with chicks circulate on the outside, 314 00:27:36,160 --> 00:27:38,040 avoiding the pressure within. 315 00:27:38,040 --> 00:27:39,800 As the weather worsens, 316 00:27:39,800 --> 00:27:43,120 they'll all have to look for a place to tuck in. 317 00:27:47,840 --> 00:27:51,000 Eventually, a huge huddle forms. 318 00:27:51,000 --> 00:27:53,200 THEY CHITTER 319 00:27:55,480 --> 00:27:58,480 While those in the centre are warm and protected, 320 00:27:58,480 --> 00:28:01,160 those on the outside are still struggling. 321 00:28:06,560 --> 00:28:08,000 To share the heat around, 322 00:28:08,000 --> 00:28:10,200 the penguins take tiny steps 323 00:28:10,200 --> 00:28:11,960 to change position. 324 00:28:11,960 --> 00:28:14,160 Waves of movement ripple through the huddle, 325 00:28:14,160 --> 00:28:17,040 giving everyone a chance to have a go in the centre. 326 00:28:21,880 --> 00:28:26,040 The huddle is so efficient, penguins in the inner core can even overheat. 327 00:28:31,080 --> 00:28:33,040 As these penguins try to cool down, 328 00:28:33,040 --> 00:28:34,800 the colony starts to break up. 329 00:28:37,200 --> 00:28:40,600 The collapse acts as a release valve, shedding excess heat. 330 00:28:52,240 --> 00:28:54,640 But it's dangerous for the chick. 331 00:28:57,160 --> 00:28:58,800 As everyone moves position, 332 00:28:58,800 --> 00:29:00,720 some mothers topple in the crush. 333 00:29:06,920 --> 00:29:09,000 She tries

it starts to reform. 340 00:29:41,000 --> 00:29:42,760 Not all have been so lucky. 341 00:29:50,800 --> 00:29:53,040 This penguin has been searching for 342 00:29:53,040 --> 00:29:54,600 her lost

wait another year. 353 00:31:36,280 --> 00:31:40,920 In Peru, the young chicks face other risks - they are hungry. 354 00:31:43,240 --> 00:31:46,840 On the shore below, their mother returns from her fishing trip. 355 00:31:46,840 --> 00:31:50,960 She has plenty of food, but getting back to her chicks won't be easy. 356 00:31:52,320 --> 00:31:54,760 The sea lions have woken up. 357 00:31:58,640

00:37:16,040 ..and out of sight of her mother. 410 00:37:19,040 --> 00:37:20,240 Her mother calls. 411 00:37:21,280 --> 00:37:23,200 LOUD CHIRPING 412 00:37:27,640 --> 00:37:30,640 But her chick is lost in a penguin maze. 413 00:37:38,880 --> 00:37:41,280 She starts to realise the danger she's in. 414 00:37:42,600 --> 00:37:44,200 PENGUINS CHIRP 415 00:37:47,320 --> 00:37:49,720 She won't survive alone for long. 416 00:37:58,200 --> 00:38:03,000 In Peru, the cameras are operating using low-light technology. 417 00:38:05,160 --> 00:38:08,400 The Humboldt chicks are long overdue a feed. 418 00:38:11,240 --> 00:38:14,440 Their mother is still trapped on the beach with the sea lions. 419 00:38:15,920 --> 00:38:18,520 But she has gained an advantage. 420 00:38:18,520 --> 00:38:20,440 She often hunts at night, 421 00:38:20,440 --> 00:38:23,520 so her night vision is better than the sea lions'. 422 00:38:23,520 --> 00:38:25,120 This gives her confidence. 423 00:38:27,360 --> 00:38:29,200 SEA LIONS GRUNT 424 00:38:36,160 --> 00:38:38,160 She holds her ground, but sea lions 425 00:38:38,160 --> 00:38:40,000 aren't the only danger here. 426 00:38:42,440 --> 00:38:44,800 Vampire bats have woken up. 427 00:38:54,400 --> 00:38:56,520 She tries to sneak away, 428 00:38:56,520 --> 00:38:58,520 but the sea lions block her path. 429 00:39:02,160 --> 00:39:04,920 The vampires skip among them, looking for a meal. 430 00:39:10,440 --> 00:39:12,280 Sea lions make a larger target 431 00:39:12,280 --> 00:39:14,080 and are easier to sneak up on. 432 00:39:20,840 --> 00:39:23,600 But he feels the bat's razor incision. 433 00:39:23,600 --> 00:39:25,800 It must find a less suspecting victim. 434 00:39:30,040 --> 00:39:33,320 The bat's saliva encourages the blood to flow. 435 00:39:33,320 --> 00:39:34,720 She's soon lapping it up. 436 00:39:38,320 --> 00:39:41,080 With the sea lions distracted by the vampires, 437 00:39:41,080 --> 00:39:43,280 the penguin creeps back to her nest. 438 00:39:57,120 --> 00:40:00,600 Her hungry chicks finally get the meal they were waiting for. 439 00:40:11,200 --> 00:40:12,840 In the Antarctic, 440 00:40:12,840 --> 00:40:14,920 the weather is on the turn again... 441 00:40:18,920 --> 00:40:20,720 ..and the chick is still lost. 442 00:40:30,800 --> 00:40:33,680 If her mother doesn't find her soon, 443 00:40:33,680 --> 00:40:36,720 she'll perish. She calls. 444 00:40:38,880 --> 00:40:41,120 But the deepening snow deadens the sound. 445 00:40:46,800 --> 00:40:48,280 She's protected by down, 446 00:40:48,280 --> 00:40:49,800 but it's not enough. 447 00:40:55,360 --> 00:40:58,040 She's beginning to struggle against the cold. 448 00:41:15,360 --> 00:41:17,560 Then, just in time, a mother's warmth. 449 00:41:48,960 --> 00:41:52,160 In the Falklands, Rockhoppercam waits for the males 450 00:41:52,160 --> 00:41:54,320 to return from their fishing trip. 451 00:42:00,280 --> 00:42:02,920 In the two weeks they've been away, they may have travelled 452 00:42:02,920 --> 00:42:05,600 over a thousand miles in their quest for food. 453 00:42:20,040 --> 00:42:23,960 They arrive in small landing parties, but numbers build, 454 00:42:23,960 --> 00:42:25,520 as they come ashore. 455 00:42:31,400 --> 00:42:34,080 Rockhoppercam watches, as they start the long ascent 456 00:42:34,080 --> 00:42:35,800 to their partners and chicks. 457 00:42:41,040 --> 00:42:43,080 Popular routes form bottlenecks. 458 00:42:47,160 --> 00:42:49,480 It's so easy to be in the wrong place. 459 00:42:58,480 --> 00:43:02,320 But Rockhoppercam always picks itself back up again. 460 00:43:08,400 --> 00:43:10,720 Their partners may be waiting, 461 00:43:10,720 --> 00:43:12,640 but once over the first hurdle, 462 00:43:12,640 --> 00:43:14,600 the males have other ideas. 463 00:43:15,840 --> 00:43:17,680 They go to the spa. 464 00:43:20,880 --> 00:43:23,480 This natural shower washes off the sea salt 465 00:43:23,480 --> 00:43:25,040 that penetrates their feathers. 466 00:43:35,400 --> 00:43:37,240 It also quenches their thirst. 467 00:43:42,200 --> 00:43:44,000 The shower is in high demand. 468 00:43:44,000 --> 00:43:46,960 Disputes break out over whose turn it is to have a go. 469 00:43:58,560 --> 00:44:01,040 No-one can bathe in peace for more than a few moments. 470 00:44:16,800 --> 00:44:19,560 But one smart penguin has an idea. 471 00:44:21,600 --> 00:44:24,000 He deploys a mountaineering technique 472 00:44:24,000 --> 00:44:25,560 known as a chimney climb. 473 00:44:27,600 --> 00:44:28,960 And at the top, 474 00:44:28,960 --> 00:44:31,080 all any penguin requires - 475 00:44:31,080 --> 00:44:33,360 his own private power shower. 476 00:44:45,280 --> 00:44:47,200 He's enjoying himself so much, 477 00:44:47,200 --> 00:44:49,520 he's in no rush to get back to his partner. 478 00:44:57,400 --> 00:44:58,840 While he was away, 479 00:44:58,840 --> 00:45:02,680 the female hasn't left her chicks' side for a single moment. 480 00:45:07,040 --> 00:45:10,040 Gulls watch for any lapse of concentration. 481 00:45:12,880 --> 00:45:14,640 CHICK CHIRRUPS 482 00:45:21,160 --> 00:45:22,640 They snatch a chick 483 00:45:22,640 --> 00:45:24,240 the moment a back is turned. 484 00:45:29,000 --> 00:45:31,520 Skuas add to the mounting toll... 485 00:45:40,360 --> 00:45:42,560 ..and soon, some pairs are left 486 00:45:42,560 --> 00:45:44,480 without any chicks at all. 487 00:45:51,760 --> 00:45:54,280 The bereaved couples are desperate. 488 00:45:57,960 --> 00:46:00,520 They look for another chick 489 00:46:00,520 --> 00:46:01,920 to care for, 490 00:46:01,920 --> 00:46:03,520 and they don't mind 491 00:46:03,520 --> 00:46:04,920 if it's someone else's. 492 00:46:07,200 --> 00:46:08,680 They plan a kidnap. 493 00:46:12,440 --> 00:46:14,480 The mother's defence is to sit tight 494 00:46:14,480 --> 00:46:16,360 and stop her chick being stolen. 495 00:46:21,680 --> 00:46:22,920 But the kidnappers 496 00:46:22,920 --> 00:46:25,000 won't be put off easily. 497 00:46:30,720 --> 00:46:32,720 Just in time, her partner returns, 498 00:46:32,720 --> 00:46:34,360 spruced up from the shower. 499 00:46:40,040 --> 00:46:42,160 He takes on the would-be kidnappers. 500 00:46:49,600 --> 00:46:51,440 The fight gets even more heated, 501 00:46:51,440 --> 00:46:54,520 but there are few tougher than a Rockhopper. 502 00:46:54,520 --> 00:46:57,400 They can take the punishment, as well as dish it out. 503 00:47:00,080 --> 00:47:02,120 The baby-snatchers have had enough 504 00:47:02,120 --> 00:47:04,000 and the male returns to his mate. 505 00:47:06,840 --> 00:47:08,560 He might need another shower, 506 00:47:08,560 --> 00:47:10,280 but at least his chick is safe. 507 00:47:17,240 --> 00:47:19,400 Kidnapping is also rife 508 00:47:19,400 --> 00:47:21,400 in the Emperor colony. 509 00:47:21,400 --> 00:47:23,960 The newly-walking chicks are irresistible to females 510 00:47:23,960 --> 00:47:25,440 that have lost their own chicks 511 00:47:25,440 --> 00:47:27,120 or failed to breed. 512 00:47:28,760 --> 00:47:30,960 The mother tries to repel the kidnappers 513 00:47:30,960 --> 00:47:33,080 with a few well-aimed pecks. 514 00:47:33,080 --> 00:47:34,840 But they won't give up. 515 00:47:41,080 --> 00:47:43,160 And others had the same idea. 516 00:47:48,440 --> 00:47:50,480 The chick heads for the main colony, 517 00:47:50,480 --> 00:47:52,880 hoping to find protection among the crowds. 518 00:48:00,880 --> 00:48:03,400 She disappears in a mass of bodies... 519 00:48:05,160 --> 00:48:07,160 ..and reappears alone. 520 00:48:11,080 --> 00:48:13,240 But it's only for a moment. 521 00:48:13,240 --> 00:48:14,800 A large crowd has gathered, 522 00:48:14,800 --> 00:48:16,520 all trying to adopt the chick. 523 00:48:18,920 --> 00:48:21,760 She's soon overwhelmed by doting admirers. 524 00:48:31,640 --> 00:48:33,520 One child snatcher tries to force 525 00:48:33,520 --> 00:48:34,960 the chick into her pouch, 526 00:48:34,960 --> 00:48:36,600 but she's way too big. 527 00:48:38,800 --> 00:48:40,360 She makes a break for it, 528 00:48:40,360 --> 00:48:42,720 then gives them the run-around through the colony. 529 00:48:57,760 --> 00:48:59,800 Finally, they have her surrounded. 530 00:48:59,800 --> 00:49:01,920 They're all desperate to mother her. 531 00:49:13,720 --> 00:49:14,920 She's in danger 532 00:49:14,920 --> 00:49:16,920 of being smothered with love. 533 00:49:24,520 --> 00:49:27,320 But the fluffball is accidently flipped away... 534 00:49:28,680 --> 00:49:30,440 ..and caught by her mother. 535 00:49:42,600 --> 00:49:45,320 She'll stay closer to her next time. 536 00:49:50,200 --> 00:49:51,720 At the Rockhopper colony, 537 00:49:51,720 --> 00:49:53,720 yet more predators are gathering. 538 00:49:57,920 --> 00:49:59,800 A striated caracara, 539 00:49:59,800 --> 00:50:01,800 another chick hunter. 540 00:50:11,520 --> 00:50:12,960 As ever, the Rockhoppers 541 00:50:12,960 --> 00:50:14,680 leap to the colony's defence. 542 00:50:17,840 --> 00:50:20,080 The caracara finds what he thinks 543 00:50:20,080 --> 00:50:21,480 is an easy meal. 544 00:50:25,360 --> 00:50:27,120 With all the real eggs hatched, 545 00:50:27,120 --> 00:50:29,000 eggcam is an irresistible temptation. 546 00:50:29,000 --> 00:50:31,920 It not only looks like a real egg... 547 00:50:33,560 --> 00:50:35,680 ..it rolls like one too. 548 00:50:57,800 --> 00:51:00,120 With eggcam finally in his claws, 549 00:51:00,120 --> 00:51:02,120 he does what comes naturally - 550 00:51:02,120 --> 00:51:04,680 takes it into the air. 551 00:51:09,080 --> 00:51:10,560 A quick readjustment, 552 00:51:10,560 --> 00:51:12,840 and eggcam captures the first aerial 553 00:51:12,840 --> 00:51:15,480 of a penguin colony, shot by a flying bird. 554 00:51:22,760 --> 00:51:24,560 But then eggcam slips from his grasp. 555 00:51:28,840 --> 00:51:32,240 But immediately, it catches the eye of a turkey vulture. 556 00:51:40,440 --> 00:51:44,080 The game continues with different players. 557 00:52:04,000 --> 00:52:07,880 Finally, eggcam is back in the Rockhopper colony. 558 00:52:13,040 --> 00:52:15,560 This childless couple can hardly believe their luck. 559 00:52:15,560 --> 00:52:18,640 Eggcam is a gift from the skies. 560 00:52:20,920 --> 00:52:22,480 She tenderly takes it into her nest. 561 00:52:31,000 --> 00:52:32,240 For a few moments, 562 00:52:32,240 --> 00:52:34,280 she even tries to incubate it. 563 00:52:34,280 --> 00:52:36,160 But she won't be fooled for long. 564 00:52:44,000 --> 00:52:47,720 Back in Peru, the rest of the fishing party have finally arrived. 565 00:52:53,240 --> 00:52:57,880 While they've been away, the nesting colony has undergone an invasion 566 00:52:57,880 --> 00:53:01,040 far greater than anything the Rockhoppers have faced. 567 00:53:06,440 --> 00:53:07,960 Their numbers 568 00:53:07,960 --> 00:53:09,680 have to be seen to be believed. 569 00:53:11,040 --> 00:53:13,560 There are half a million birds in all. 570 00:53:17,160 --> 00:53:18,600 Guanay cormorants. 571 00:53:22,240 --> 00:53:24,280 Global weather has pushed the birds southwards 572 00:53:24,280 --> 00:53:27,880 and they've gathered in far greater numbers than normal. 573 00:53:30,360 --> 00:53:33,400 For the returning males, it's utterly bewildering. 574 00:53:38,400 --> 00:53:40,920 For the females and their young, 575 00:53:40,920 --> 00:53:42,280 it's a disaster. 576 00:53:52,880 --> 00:53:55,920 The cormorants nest outside the colony, 577 00:53:55,920 --> 00:53:57,760 but the penguins and their chicks 578 00:53:57,760 --> 00:53:59,440 are just where these invaders 579 00:53:59,440 --> 00:54:00,880 prefer to take off. 580 00:54:02,760 --> 00:54:04,920 Their chicks could easily be trampled 581 00:54:04,920 --> 00:54:07,240 if the cormorants overshoot the runway. 582 00:54:10,240 --> 00:54:11,800 The young take cover 583 00:54:11,800 --> 00:54:13,840 as the invaders move ever closer, 584 00:54:13,840 --> 00:54:15,640 pushed forward by the others, 585 00:54:15,640 --> 00:54:17,360 eager to take off. 586 00:54:24,440 --> 00:54:26,520 And that was just the start. 587 00:54:26,520 --> 00:54:29,320 Thousands upon thousands are stacked up behind. 588 00:54:32,240 --> 00:54:34,480 The Humboldts just have to hold their ground 589 00:54:34,480 --> 00:54:36,960 and protect their chicks the best they can. 590 00:54:40,840 --> 00:54:43,080 She shields her offspring. 591 00:54:43,080 --> 00:54:46,160 She has never experienced anything like it. 592 00:55:03,760 --> 00:55:06,800 She even tries to snatch the cormorants from the air. 593 00:55:14,560 --> 00:55:16,960 As the cormorants stream out to sea, 594 00:55:16,960 --> 00:55:18,760 the pressure is released. 595 00:55:25,040 --> 00:55:27,760 It takes a whole hour for them to leave. 596 00:55:33,960 --> 00:55:35,960 With most of the cormorants gone, 597 00:55:35,960 --> 00:55:38,200 the males can finally return to their young. 598 00:55:44,960 --> 00:55:47,520 The family is reunited, 599 00:55:47,520 --> 00:55:50,320 and Dad has brought back dinner. 600 00:56:03,480 --> 00:56:05,160 At the Emperor colony, 601 00:56:05,160 --> 00:56:06,440 the freezing winter 602 00:56:06,440 --> 00:56:08,480 has kept other predators at bay. 603 00:56:08,480 --> 00:56:10,680 But spring brings new dangers. 604 00:56:21,280 --> 00:56:23,360 A giant petrel suddenly arrives, 605 00:56:23,360 --> 00:56:25,640 looking for a meal. 606 00:56:26,640 --> 00:56:28,840 He weighs up his options. 607 00:56:30,880 --> 00:56:34,640 Chicks protected by their mother are difficult to catch. 608 00:56:40,360 --> 00:56:42,880 Mum's pouch is now of little use, 609 00:56:42,880 --> 00:56:45,600 it just hides the danger from view. 610 00:56:45,600 --> 00:56:48,360 But it's the mother that keeps the petrel at bay. 611 00:56:51,840 --> 00:56:54,440 While some rely on their mother for protection, 612 00:56:54,440 --> 00:56:56,200 others huddle together. 613 00:56:58,640 --> 00:57:00,280 He tests the group's reaction, 614 00:57:00,280 --> 00:57:01,840 to see if any will run. 615 00:57:06,480 --> 00:57:07,760 By breaking up the huddle, 616 00:57:07,760 --> 00:57:09,360 he can isolate a victim. 617 00:57:20,040 --> 00:57:21,800 He gets one. 618 00:57:33,280 --> 00:57:35,600 But he only has it by her feathers. 619 00:57:39,360 --> 00:57:40,640 She breaks free 620 00:57:40,640 --> 00:57:42,160 and runs to her mother. 621 00:57:48,240 --> 00:57:50,800 PENGUIN SQUAWKS 622 00:57:53,800 --> 00:57:55,640 Petrels are huge birds, 623 00:57:55,640 --> 00:57:57,440 but they still won't mess with 624 00:57:57,440 --> 00:57:58,840 an adult Emperor. 625 00:58:04,400 --> 00:58:06,400 Protected by her mother, 626 00:58:06,400 --> 00:58:08,960 the chick survived another day. 627 00:58:08,960 --> 00:58:11,320 But soon, the parents will leave 628 00:58:11,320 --> 00:58:14,280 and these chicks have to stand on their own two feet. 629 00:58:17,640 --> 00:58:20,120 Next time, from the frozen Antarctic 630 00:58:20,120 --> 00:58:21,760 to the scorching desert, 631 00:58:21,760 --> 00:58:23,440 we discover the challenges 632 00:58:23,440 --> 00:58:24,600 faced by all our chicks, 633
