1 00:00:06,060 --> 00:00:11,120 We have explored almost every corner of our planet, 2 00:00:11,120 --> 00:00:15,280 and it's easy to imagine that there's nothing left to discover. 3 00:00:21,160 --> 00:00:24,720 But the natural world can still surprise us... 4 00:00:32,080 --> 00:00:35,200 ..with astonishing, wild places... 5 00:00:36,960 --> 00:00:39,160 ..remarkable spectacles... 6 00:00:41,840 --> 00:00:44,520 ..and breathtaking animal dramas. 7 00:00:50,640 --> 00:00:55,640 In this programme, we celebrate highlights from Planet Earth III. 8 00:00:59,840 --> 00:01:02,480 We travel across the globe, 9 00:01:02,480 --> 00:01:04,520 from hidden forests... 10 00:01:07,880 --> 00:01:10,200 ..and turbulent coasts... 11 00:01:13,920 --> 00:01:16,880 ..through vast, unexplored deserts. 12 00:01:20,840 --> 00:01:24,360 We will also see in this changing world 13 00:01:24,360 --> 00:01:28,240 how animals are adapting to new challenges. 14 00:01:34,840 --> 00:01:38,080 This is Planet Earth III. 15 00:02:26,680 --> 00:02:30,280 This is the most ancient desert on the planet. 16 00:02:32,880 --> 00:02:36,160 The Namib, in Southwest Africa. 17 00:02:44,800 --> 00:02:48,320 It is one of the hottest places on earth. 18 00:02:56,000 --> 00:02:59,400 Yet this male ostrich and his mate... 19 00:03:00,760 --> 00:03:03,520 ..have come here to start a family. 20 00:03:07,480 --> 00:03:11,240 Few predators venture out during the heat of the day. 21 00:03:13,520 --> 00:03:17,040 But such safety comes at a price. 22 00:03:19,280 --> 00:03:22,400 Out in the open, the newly hatched chicks 23 00:03:22,400 --> 00:03:25,840 are exposed to the crushing heat of the sun. 24 00:03:30,120 --> 00:03:32,880 But not all of the brood have hatched. 25 00:03:36,280 --> 00:03:40,280 Until they do, the family will stay here. 26 00:03:50,160 --> 00:03:53,640 The adults take it in turns to protect the brood. 27 00:03:57,200 --> 00:04:01,560 So, whilst the female takes a well-earned break, 28 00:04:01,560 --> 00:04:05,920 the male takes over for the most testing shift. 29 00:04:11,120 --> 00:04:14,560 He gently rolls the unhatched eggs... 30 00:04:16,120 --> 00:04:18,720 ..calling to the young within them. 31 00:04:21,800 --> 00:04:24,520 He doesn't want to leave anyone behind. 32 00:04:33,880 --> 00:04:39,560 The temperature continues to rise by five degrees Celsius every hour. 33 00:04:43,440 --> 00:04:45,560 CHICK CHIRPS 34 00:04:47,760 --> 00:04:50,560 He protects the chicks that have emerged... 35 00:04:51,840 --> 00:04:54,440 ..shading them with his own body. 36 00:04:58,520 --> 00:05:01,800 At the end of another gruelling day in the sun... 37 00:05:04,680 --> 00:05:07,560 ..he's lost almost all his energy. 38 00:05:19,760 --> 00:05:22,680 But he must resist the urge to rest. 39 00:05:42,880 --> 00:05:46,600 The cool of the night brings some relief, 40 00:05:46,600 --> 00:05:50,240 but now, predators are out and about. 41 00:05:54,320 --> 00:05:59,360 JACKAL BARKS 42 00:06:02,480 --> 00:06:05,400 JACKAL MOANS 43 00:06:31,760 --> 00:06:35,440 It's going to be a long night. 44 00:06:47,440 --> 00:06:50,320 Dawn brings a surprise. 45 00:06:54,920 --> 00:06:58,080 Three additions to the family... 46 00:07:00,080 --> 00:07:03,200 ..to greet the returning female. 47 00:07:09,360 --> 00:07:11,200 But there's a problem. 48 00:07:12,800 --> 00:07:16,880 The chicks won't survive another day in these temperatures. 49 00:07:22,520 --> 00:07:25,720 Yet the male is reluctant to leave. 50 00:07:27,440 --> 00:07:31,120 Some of the eggs have still not hatched. 51 00:07:40,240 --> 00:07:42,720 But time has run out. 52 00:07:51,560 --> 00:07:53,680 They must depart. 53 00:08:21,360 --> 00:08:24,520 Just a few minutes too late. 54 00:08:51,080 --> 00:08:53,480 CHICK CHIRPS 55 00:09:14,480 --> 00:09:18,080 Alone and without the protection of its parents, 56 00:09:18,080 --> 00:09:21,080 this hatchling's chances are slim. 57 00:09:33,560 --> 00:09:35,600 CHICK CHIRPS 58 00:09:53,720 --> 00:09:56,080 CHIRPING CONTINUES 59 00:10:12,800 --> 00:10:14,600 OSTRICH CHIRPS 60 00:10:23,360 --> 00:10:24,960 CHIRPING CONTINUES 61 00:10:34,000 --> 00:10:37,480 BOTH CHIRP 62 00:11:07,920 --> 00:11:11,920 These ostrich have overcome a battle 63 00:11:11,920 --> 00:11:14,640 with the deadly power of the sun. 64 00:11:23,640 --> 00:11:27,600 But its intensity can also be life-giving. 65 00:11:34,080 --> 00:11:37,960 Here in the shallow seas of North America, 66 00:11:37,960 --> 00:11:41,160 the sun fuels the growth 67 00:11:41,160 --> 00:11:43,600 of an underwater forest. 68 00:11:54,000 --> 00:11:55,840 Giant kelp. 69 00:11:58,720 --> 00:12:02,600 One of the fastest-growing organisms on the planet. 70 00:12:02,600 --> 00:12:06,240 It can increase its length by up to two feet a day... 71 00:12:07,760 --> 00:12:11,880 ..and eventually reach the height of a 12-storey building. 72 00:12:22,520 --> 00:12:27,320 These forests are nurseries for young horn sharks. 73 00:12:30,960 --> 00:12:35,200 As the sun begins to set, they leave their daytime shelter... 74 00:12:36,480 --> 00:12:41,600 ..and set off into the heart of the kelp forest to find food. 75 00:12:51,880 --> 00:12:54,000 Barely half a metre long, 76 00:12:54,000 --> 00:12:57,800 this little shark is extremely vulnerable. 77 00:13:04,480 --> 00:13:06,400 There are monsters here. 78 00:13:07,480 --> 00:13:10,440 A giant sea bass 79 00:13:10,440 --> 00:13:13,080 weighing over 200kg... 80 00:13:16,440 --> 00:13:20,200 ..and wolf eels with big teeth 81 00:13:20,200 --> 00:13:23,120 that can crush little red sea urchins. 82 00:13:26,160 --> 00:13:29,840 But the biggest danger comes from other sharks. 83 00:13:33,600 --> 00:13:35,440 Hound sharks... 84 00:13:40,280 --> 00:13:44,120 ..and huge broadnose sevengills. 85 00:13:56,120 --> 00:14:00,480 In this forest, it pays to keep a low profile. 86 00:14:34,000 --> 00:14:36,320 An angel shark. 87 00:14:39,640 --> 00:14:43,760 One of the most deadly sharks in the kelp forest 88 00:14:43,760 --> 00:14:47,160 and certainly the best camouflaged. 89 00:14:58,080 --> 00:15:01,640 An angel shark will lie in wait for days. 90 00:15:12,200 --> 00:15:14,520 But this one 91 00:15:14,520 --> 00:15:18,200 has already attracted too much attention. 92 00:15:24,760 --> 00:15:27,120 It's not welcome here. 93 00:15:34,040 --> 00:15:36,400 Now the coast is clear. 94 00:15:44,840 --> 00:15:47,720 But angel sharks hunt around the clock. 95 00:15:58,680 --> 00:16:02,280 Openings for breathing called spiracles 96 00:16:02,280 --> 00:16:05,480 blow out sand that helps cover its body. 97 00:16:13,120 --> 00:16:15,440 The trap is set. 98 00:16:27,280 --> 00:16:29,720 Staying close to the seabed 99 00:16:29,720 --> 00:16:33,200 is a good way to avoid most predators. 100 00:17:22,920 --> 00:17:25,880 Faster than the blink of an eye. 101 00:17:29,480 --> 00:17:31,600 But it's not over yet. 102 00:17:44,040 --> 00:17:47,320 Horn sharks have a secret weapon. 103 00:17:53,040 --> 00:17:57,200 Sharp spikes keep them very much off the menu for most... 104 00:18:00,840 --> 00:18:06,120 ..so this young horn shark can continue hunting... 105 00:18:08,040 --> 00:18:10,040 ..safe from attack. 106 00:18:15,840 --> 00:18:18,520 From kelp forests... 107 00:18:18,520 --> 00:18:20,880 ..to rainforests, 108 00:18:20,880 --> 00:18:25,520 animals must develop remarkable strategies in order to survive. 109 00:18:36,960 --> 00:18:39,280 This is a tree hopper. 110 00:18:41,000 --> 00:18:42,520 Here in the Amazon, 111 00:18:42,520 --> 00:18:45,000 there are hundreds of different species of them... 112 00:18:46,640 --> 00:18:50,720 ..and they come in an extraordinary variety of shapes. 113 00:18:50,720 --> 00:18:55,040 HOPPER HUMS 114 00:19:00,600 --> 00:19:02,680 But they also communicate... 115 00:19:04,280 --> 00:19:06,320 ..in a remarkable way. 116 00:19:06,320 --> 00:19:09,000 HOPPERS CHIRP 117 00:19:17,920 --> 00:19:20,560 Most of these calls we can only hear 118 00:19:20,560 --> 00:19:23,000 by using special microphones. 119 00:19:29,440 --> 00:19:33,000 Each tree hopper species has its own repertoire... 120 00:19:33,000 --> 00:19:34,920 HOPPER HOOTS 121 00:19:36,720 --> 00:19:38,720 HOPPER RUMBLES 122 00:19:38,720 --> 00:19:43,760 HOPPER COOS 123

with her young... 132 00:20:36,520 --> 00:20:39,080 ..encouraging them to stay together... 133 00:20:41,000 --> 00:20:43,040 ..so that she can protect them... 134 00:20:47,240 --> 00:20:51,440 ..for there are plenty here waiting to eat young tree hoppers. 135 00:20:56,400 --> 00:20:58,960 Ants - on the hunt. 136 00:21:05,120 --> 00:21:08,280 Tree hoppers know how to defend themselves. 137 00:21:23,280 --> 00:21:26,760 But not all threats are so easily dealt with. 138 00:21:37,760 --> 00:21:39,760 An assassin bug. 139 00:21:42,800 --> 00:21:45,200 Armed with piercing mouth parts 140 00:21:45,200 --> 00:21:47,760 and sticky front legs. 141 00:21:53,600 --> 00:21:58,960 Capable of literally sucking the life out of her entire brood. 142 00:22:06,560 --> 00:22:10,360 She uses her body to block the assassin's path... 143 00:22:13,480 --> 00:22:15,640 ..but she can't guard them all. 144 00:22:19,040 --> 00:22:23,760 She needs help from friends in high places. 145 00:22:26,840

Wagner 149 00:22:49,920 --> 00:22:53,280 This is more than the assassin bargained for. 150 00:23:07,120 --> 00:23:08,960 Mission accomplished. 151 00:23:11,320 --> 00:23:13,800 Her brood are safe... 152 00:23:17,880 --> 00:23:20,760 ..and the bees claim a reward. 153 00:23:24,760 --> 00:23:27,640 A little tickle on a tree hopper's back... 154 00:23:30,000 --> 00:23:34,680 ..and the hopper excretes some of its partly digested plant sap... 155 00:23:35,760 --> 00:23:39,800 ..which we call, rather flatteringly, honeydew. 156 00:23:42,680 --> 00:23:45,480 A sweet reward for protecting them. 157 00:24:00,680 --> 00:24:04,560 In the Amazon, it pays to work together. 158 00:24:18,120 --> 00:24:20,760 On the open grasslands of Africa... 159 00:24:22,680 --> 00:24:25,360 ..where many eyes watch for danger... 160 00:24:28,960 --> 00:24:33,360 ..hunters are driven to new heights to gain the advantage. 161 00:24:39,320 --> 00:24:42,360 This leopardess, believe it or not, 162 00:24:42,360 --> 00:24:45,320 is ready to hunt at a moment's notice. 163 00:24:49,280 --> 00:24:51,920 She is one of the few special leopards 164 00:24:51,920 --> 00:24:54,360 that have learnt to hide in the tree tops 165 00:24:54,360 --> 00:24:57,360 and wait for their prey to come to them. 166 00:25:03,000 --> 00:25:06,040 Without making a sound, 167 00:25:06,040 --> 00:25:08,200 she gets into position. 168 00:26:38,240 --> 00:26:40,120 Not this time. 169 00:26:47,000 --> 00:26:50,480 And now her presence is known to all. 170 00:26:52,280 --> 00:26:54,080 BABOON BARKS 171 00:27:04,360 -->

up to a branch 174 00:27:45,080 --> 00:27:48,200 nine metres above the ground. 175 00:27:53,720 --> 00:27:57,120 She's higher than the roof of a two-storey house. 176 00:28:02,440 --> 00:28:06,560 Leopards have killed themselves jumping from these heights. 177 00:29:00,480 --> 00:29:04,120 To succeed on these equatorial grasslands, 178 00:29:04,120 --> 00:29:06,120 you must be adaptable... 179 00:29:09,040 --> 00:29:11,240 ..and sometimes brave. 180 00:29:20,160 --> 00:29:22,320 Here in southern Africa, 181 00:29:22,320 --> 00:29:27,320 the lives of animals are driven by huge seasonal changes. 182 00:29:38,360 --> 00:29:42,560 Every year, over 5,000 square miles of grassland 183 00:29:42,560 --> 00:29:44,920 are transformed by water. 184 00:29:47,480 --> 00:29:50,280 The Okavango

family. 188 00:30:40,000 --> 00:30:41,760 A lily-trotter. 189 00:30:43,440 --> 00:30:45,400 EGGSHELL CRACKS 190 00:30:48,280 --> 00:30:51,640 And he is a father on duty. 191 00:31:02,640 -->

protector. 198 00:31:53,560 --> 00:31:57,520 Walking on water is not straightforward... 199 00:32:00,240 --> 00:32:04,440 ..so he must show them how to be a lily-trotter. 200 00:32:26,080 --> 00:32:30,040 The floodwaters make the perfect training ground. 201 00:32:46,280 --> 00:32:48,680 And in two weeks... 202 00:32:50,160 --> 00:32:53,240 ..his chicks not only double in size... 203

seals risk their lives every time they set out to eat. 250 00:40:26,520 --> 00:40:30,520 Powerful ocean currents attract huge shoals of fish. 251 00:40:39,760 --> 00:40:42,080 But in recent years, 252 00:40:42,080 --> 00:40:46,720 this stretch has attracted increased numbers of great whites, too. 253 00:40:50,360 --> 00:40:52,720 The great whites are shrewd hunters 254 00:40:52,720 --> 00:40:55,680 and use whatever cover is available. 255 00:41:24,880 --> 00:41:28,440 This shark won't need to eat for another few days... 256 00:41:30,200 --> 00:41:32,840 SEAGULLS CAW 257 00:41:32,840 -->

have explosive acceleration... 264 00:42:23,240 --> 00:42:27,480 ..hitting top speed with just five swipes of their tails. 265 00:42:38,480 --> 00:42:43,600 Cornered, the seals keep close to the

something astonishing. 269 00:43:47,960 --> 00:43:49,640 Together... 270 00:43:50,680 --> 00:43:52,840 ..they turn on their enemy. 271 00:44:05,560 --> 00:44:08,800 As more join, the mob grows... 272

275 00:44:58,760 --> 00:45:01,840 drive the world's most notorious predator... 276 00:45:04,040 --> 00:45:06,240 ..back out to sea. 277 00:45:15,080 --> 00:45:18,000 These seals have found a remarkable way 278 00:45:18,000 --> 00:45:21,160 to meet the demands of life in the wild. 279 00:45:23,080 --> 00:45:27,240 But many animals must now rise to a new challenge... 280 00:45:29,240 -->

gruelling... 352 00:53:45,000 --> 00:53:49,200 ..and the ebbing tide has exposed a rocky reef. 353 00:53:54,360 --> 00:53:57,280 It has already claimed many lives... 354 00:54:02,040 --> 00:54:06,480
