00:18:47,850 While the eagle has to sit out icy storms, 211 00:18:47,850 --> 00:18:50,543 the marmot sleep through the winter weather's whims. 212 00:18:50,543 --> 00:18:53,166 [hay rustling] 213 00:18:56,411 --> 00:18:59,690 They survive on their body's storage of fat and water 214 00:19:01,657 --> 00:19:05,799 and benefit from thick fur and a burrow padded with dry hay. 215 00:19:08,043 --> 00:19:10,701 [wind howling] 216 00:19:12,151 --> 00:19:15,706 While the weather outside pushes everyone to the limits, 217 00:19:15,706 --> 00:19:18,329 it's safe and cozy inside 218 00:19:18,329 --> 00:19:21,643 to doze deeply and for a long time. 219 00:19:25,957 --> 00:19:28,546 There's not the slightest draft down here 220 00:19:28,546 --> 00:19:32,171 no matter how hard the storm may blow outside. 221 00:19:32,171 --> 00:19:34,794 [wind howling] 222 00:19:46,495 --> 00:19:48,290 Mountain hares and ptarmigan 223 00:19:48,290 --> 00:19:51,224 use the deep snow to their advantage. 224 00:19:51,224 --> 00:19:53,675 Well protected against strong winds, 225 00:19:53,675 --> 00:19:57,368 they calmly weather any storm for days on end. 226 00:20:11,934 --> 00:20:13,246 The grounded eagle 227 00:20:13,246 --> 00:20:15,214 has nothing but its plumage for protection. 228 00:20:22,531 --> 00:20:24,602 Thanks to their fluffy underwear, 229 00:20:24,602 --> 00:20:26,328 eagles can withstand temperatures 230 00:20:26,328 --> 00:20:28,572 as low as minus 30 centigrade. 231 00:20:30,021 --> 00:20:32,852 But stiff, heavy ice on the outer plumage 232 00:20:32,852 --> 00:20:34,509 can be a serious hazard. 233 00:20:34,509 --> 00:20:37,166 [dreary music] 234 00:21:00,776 --> 00:21:03,400 Even in the deep of the alpine winter, 235 00:21:03,400 --> 00:21:06,057 there will be warm, sunny days. 236 00:21:06,057 --> 00:21:08,508 Southern slopes can almost feel like summer. 237 00:21:10,476 --> 00:21:13,272 [wings flapping] 238 00:21:15,170 --> 00:21:18,311 These specialists have been safe from windchill, 239 00:21:18,311 --> 00:21:21,141 but they've been sitting motionless for quite some time. 240 00:21:28,321 --> 00:21:32,291 Now the eagle could hunt if it wasn't for the icy feathers. 241 00:21:44,337 --> 00:21:47,236 In the cold, red deer lower their heart rate 242 00:21:47,236 --> 00:21:48,928 and hardly move. 243 00:21:48,928 --> 00:21:51,171 Now they reboot their circulation. 244 00:21:58,524 --> 00:22:01,699 Many young foxes do not survive their first winter. 245 00:22:03,287 --> 00:22:06,428 [lighthearted music] 246 00:22:16,127 --> 00:22:19,752 Harsh weather eliminates the old and weak of any species. 247 00:22:26,241 --> 00:22:29,244 Their death gives young, inexperienced hunters 248 00:22:29,244 --> 00:22:31,211 a chance to make it through the winter. 249 00:22:37,217 --> 00:22:40,048 [wings flapping] 250 00:22:40,048 --> 00:22:44,259 The eagle can finally move again, but the ordeal isn't over. 251 00:22:48,712 --> 00:22:51,508 [eagle

00:23:40,764 --> 00:23:43,905 chamois tried to avoid deep snow and wind 259 00:23:43,905 --> 00:23:46,148 by staying close to overhanging rocks. 260 00:23:47,080 --> 00:23:49,807 [snow rustling] 261 00:23:59,092 --> 00:24:01,819 But high above them, along the ridges, 262 00:24:01,819 --> 00:24:04,857 the wind has piled up tons of snow. 263 00:24:04,857 --> 00:24:07,963 [avalanche rumbling] 264

pressure wave of an avalanche 271 00:25:07,402 --> 00:25:09,611 can flatten an entire forest. 272 00:25:10,923 --> 00:25:14,409 But underneath rock overhangs, chamois stay put 273 00:25:14,409 --> 00:25:16,825 while tons of snow thunder overhead. 274 00:25:22,244 --> 00:25:24,868 [wind howling] 275 00:25:29,320 --> 00:25:32,323 [ravens squawking] 276 00:25:33,152 --> 00:25:35,637 The ravens too stay calm. 277 00:25:35,637 --> 00:25:37,708 They actually welcome an avalanche. 278 00:25:37,708 --> 00:25:39,399 [ravens squawking] 279 00:25:39,399 --> 00:25:42,402 [ravens squawking] 280

00:25:57,176 --> 00:25:59,661 Again, it's the ravens that show the young eagle 284 00:25:59,661 --> 00:26:01,456 how to get through the winter. 285 00:26:11,328 --> 00:26:14,020 The homeless youngster already knows that resident adults 286 00:26:14,020 --> 00:26:19,025 are not exactly welcoming, but hunger is stronger than fear. 287 00:26:20,026 --> 00:26:22,891 [wings flapping] [eagle screeching]

vultures, foxes, and martins 298 00:27:08,454 --> 00:27:09,731 will soon arrive for the funeral feast. 299 00:27:11,181 --> 00:27:14,494 Without avalanches, many of them would never see the spring.

412 00:38:26,856 --> 00:38:28,513 Streams are in spate. 413 00:38:29,652 --> 00:38:31,861 From the bubbling of a thousand brooks, 414 00:38:31,861 --> 00:38:34,070 a strange percussion takes its cue. 415 00:38:34,070 --> 00:38:37,625 [capercaillie vocalizing] 416 00:38:40,214 --> 00:38:44,045 To capercaillie hens, this sound is music. 417 00:38:44,045 --> 00:38:47,704 [capercaillies vocalizing] 418 00:38:53,123 --> 00:38:56,437 The artist is eager to impress the female audience. 419 00:38:56,437 --> 00:38:59,992 [capercaillie vocalizing] 420 00:39:03,237 --> 00:39:06,240 Flashy iridescence, high jumps, 421 00:39:06,240 --> 00:39:10,313 and wildly flapping wings on a carefully chosen stage 422 00:39:10,313 --> 00:39:12,384 are sending a message. 423 00:39:12,384 --> 00:39:13,281 Look at me. 424 00:39:14,248 --> 00:39:17,078 [wings flapping] 425 00:39:18,079 --> 00:39:22,187 [capercaillie vocalizing] 426 00:39:22,187 --> 00:39:26,398 Enchanted, a female fan has dived down from the gallery 427 00:39:26,398 --> 00:39:28,296 right onto the stage floor. 428 00:39:29,263 --> 00:39:31,334 She too has something to offer. 429 00:39:31,334 --> 00:39:34,095 [capercaillie vocalizing] 430 00:39:34,095 --> 00:39:37,651 [capercaillie vocalizing] 431 00:39:43,104 --> 00:39:45,106 [capercaillie vocalizing] 432 00:39:45,106 --> 00:39:46,970 He's got what he wanted, 433 00:39:46,970 --> 00:39:48,972 but it's not the end of the show, 434 00:39:48,972 --> 00:39:50,871 which has turned to the neighbors. 435 00:39:50,871 --> 00:39:54,461 [capercaillies vocalizing] 436 00:40:00,881 --> 00:40:03,677 [wings flapping] 437 00:40:06,300 --> 00:40:09,579 To be enamored, embattled, and embroiled 438 00:40:09,579 --> 00:40:12,479 means to be blind to one's surroundings. 439 00:40:12,479 --> 00:40:15,620 [apprehensive music] 440 00:40:27,148 --> 00:40:30,358 This hunter, however, is anything but blind. 441 00:40:39,195 --> 00:40:41,818 Careful calculation is critical. 442 00:40:43,958 --> 00:40:47,168 [apprehensive music] 443 00:40:47,168 --> 00:40:49,067 With an eagle's wingspan, 444 00:40:49,067 --> 00:40:51,759 a rapid attack between the trees is risky. 445 00:40:55,211 --> 00:40:58,870 [capercaillie vocalizing] 446 00:40:58,870 --> 00:41:01,562 [wings flapping] 447 00:41:04,841 --> 00:41:06,325 [wings flapping] 448 00:41:06,325 --> 00:41:09,121 For the male capercaillie, it's one less competitor. 449 00:41:10,571 --> 00:41:14,057 For the young eagle, it's another lesson, 450 00:41:14,057 --> 00:41:17,233 how a master hunter takes possession of its prey. 451 00:41:19,994 --> 00:41:23,101 The youngster won't get anything here today. 452 00:41:23,101 --> 00:41:27,415 Richer in experience but still hungry, he moves on. 453 00:41:31,523 --> 00:41:35,182 On remaining snow fields, chamois mothers and their kids 454 00:41:35,182 --> 00:41:38,150 are literally chilling during the hot, midday hours. 455 00:41:40,670 --> 00:41:43,811 [lighthearted music] 456 00:41:47,194 --> 00:41:49,921 A chamois kindergarten, 457 00:41:49,921 --> 00:41:52,510 a place for rollicking and frolicking. 458 00:42:08,249 --> 00:42:10,010 But not all the kids are healthy. 459 00:42:15,705 --> 00:42:19,295 Seen from above, the landscape has completely changed, 460 00:42:19,295 --> 00:42:23,023 from monotonous white to lush green grassland, 461 00:42:23,023 --> 00:42:25,335 dotted with bodies of water, 462 00:42:25,335 --> 00:42:27,303 reflecting the sky once more. 463 00:42:32,273 --> 00:42:35,967 Looking up, the same young eagle keeps appearing in the sky. 464 00:42:52,121 --> 00:42:55,227 This is exactly how the mother hunted back in the autumn. 465 00:42:55,227 --> 00:42:57,954 [eagle chirping] 466 00:43:09,621 --> 00:43:13,245 Now there's also a new curiosity in peers. 467 00:43:13,245 --> 00:43:15,662 And apparently it's mutual. 468 00:43:21,840 --> 00:43:24,602 [wings flapping] 469 00:43:32,575 --> 00:43:34,784 The weakened chamois kid seeks warmth 470 00:43:34,784 --> 00:43:37,166 while the others are still playing in the snow. 471 00:43:40,307 --> 00:43:43,621 As the herd moves on, he's left behind. 472 00:43:43,621 --> 00:43:47,107 [apprehensive music] 473 00:43:47,107 --> 00:43:48,591 The eagle has noticed. 474 00:43:52,284 --> 00:43:55,080 [eagle chirping] 475 00:44:00,258 --> 00:44:01,224 Where is the mother? 476 00:44:02,191 --> 00:44:04,538 [chamois bleating] 477 00:44:04,538 --> 00:44:07,645 [apprehensive music] 478 00:44:09,163 --> 00:44:11,476 All alone, its chances are slim. 479 00:44:20,865 --> 00:44:22,314 The herd is long gone. 480 00:44:24,075 --> 00:44:27,181 The eagle need no longer worry about the mothers. 481 00:44:35,465 --> 00:44:38,952 The young hunter remembers one lesson. 482 00:44:38,952 --> 00:44:42,093 [suspenseful music] 483 00:44:45,234 --> 00:44:46,994 Be silent when you hunt. 484 00:45:03,183 --> 00:45:06,980 Until the last moment, the target should remain oblivious. 485 00:45:11,260 --> 00:45:15,126 [apprehensive music] 486 00:45:15,126 --> 00:45:18,163 [suspenseful music] 487 00:45:26,862 --> 00:45:29,140 [lighthearted music] 488 00:45:29,140 --> 00:45:31,314 The first glide with a heavy load. 489 00:45:49,505 --> 00:45:51,369 Making a kill is one thing. 490 00:45:54,544 --> 00:45:57,444 [eagle chirping] 491 00:46:00,654 --> 00:46:03,174 Taking possession is quite another. 492 00:46:10,353 --> 00:46:13,667 This pose clearly signals, it's mine. 493 00:46:15,289 --> 00:46:18,672 [eagle chirping] 494 00:46:18,672 --> 00:46:21,813 But there's nothing to be feared from this visitor. 495 00:46:21,813 --> 00:46:24,678 It's a bird of the same age, a male. 496 00:46:25,817 --> 00:46:27,198 And this? 497 00:46:27,198 --> 00:46:31,064 A female, and therefore bigger and more powerful. 498 00:46:34,274 --> 00:46:37,449 As a male eagle, you don't mess with a female. 499 00:46:37,449 --> 00:46:38,899 [eagle chirping] [majestic music] 500 00:46:38,899 --> 00:46:40,694 But another encounter is likely. 501 00:46:47,218 --> 00:46:50,738 The sky above the Alps may seem like an infinite void, 502 00:46:51,774 --> 00:46:54,397 but eagles can cross enormous spaces. 503 00:46:55,951 --> 00:46:58,367 Encounters are inevitable, 504 00:46:58,367 --> 00:46:59,920 especially in this season 505 00:46:59,920 --> 00:47:02,889 when hundreds of young eagles are exploring their world. 506 00:47:05,339 --> 00:47:08,239 [eagle chirping] 507 00:47:12,243 --> 00:47:14,555 Young eagles tend to team up. 508 00:47:14,555 --> 00:47:17,282 They learn from each other and hunt together. 509 00:47:24,772 --> 00:47:26,844 An intimate, parallel flight. 510 00:47:27,672 --> 00:47:29,260 This could become a friendship. 511 00:47:33,091 --> 00:47:34,541 Maybe more. 512 00:47:34,541 --> 00:47:36,336 But there's no hurry. 513 00:47:36,336 --> 00:47:38,407 These two still have a long way to go 514 00:47:38,407 --> 00:47:40,616 before sharing airspace of their own. 515 00:47:44,171 --> 00:47:46,415 Golden eagles used to find breeding space 516 00:47:46,415 --> 00:47:47,761 across all of Europe. 517 00:47:48,935 --> 00:47:51,869 Now the Alps are their last large refuge. 518 00:47:57,012 --> 00:48:00,222 In four to five years, they will be sexually mature. 519 00:48:00,222 --> 00:48:01,430 [lighthearted music] 520 00:48:01,430 --> 00:48:03,294 Those years of roaming will be tough. 521 00:48:08,057 --> 00:48:10,922 [eagle chirping] 522 00:48:13,752 --> 00:48:16,169 Just one out of three nestlings 523 00:48:16,169 --> 00:48:19,137 ever glides over the peaks at the age of one. 524 00:48:20,552 --> 00:48:24,039 And becoming a master glider and hunter will take time. 525 00:48:36,534 --> 00:48:39,433 Only one in five succeeds in mating and breeding. 526 00:48:39,433 --> 00:48:41,021 [majestic music] 527 00:48:41,021 --> 00:48:44,749 Natural selection is rigorous, and much depends on luck. 528 00:48:51,998 --> 00:48:55,242 [wings flapping] 529 00:48:55,242 --> 00:48:59,108 Finding a place in this steep world and claiming it 530 00:49:01,593 --> 00:49:03,941 can only be achieved as a pair. 531 00:49:07,979 --> 00:49:10,257 [eagle chirping] 532 00:49:10,257 --> 00:49:14,296 Against all the odds, this young eagle has come a long way. 533 00:49:15,124 --> 00:49:17,851 With a partner, chances improve. 534 00:49:19,128 --> 00:49:22,373 The future fate of this remarkable young female 535 00:49:22,373 --> 00:49:24,651 is still in the stars. 536 00:49:24,651 --> 00:49:26,964 But it's individuals like her 537 00:49:26,964 --> 00:49:31,278 who ensure that the eagle's cry, the call of the wild, 538 00:49:31,278 --> 00:49:35,075 continues to echo among the peaks of the Alps. 539 00:49:35,903 --> 00:49:38,734 [majestic music]
