1 00:00:06,800 --> 00:00:10,600 Our planet is home to millions of different species. 2 00:00:18,480 --> 00:00:21,280 The big and the powerful capture our attention. 3 00:00:24,000 --> 00:00:27,040 But there is another story to tell. 4 00:00:27,040 --> 00:00:33,520 Beneath our feet are hidden - almost magical worlds teeming with 5 00:00:33,520 --> 00:00:36,360 extraordinary little creatures. 6 00:00:37,480 --> 00:00:39,040 BELLOWING 7 00:00:39,040 --> 00:00:42,040 The world looks very different to them. 8 00:00:43,880 --> 00:00:48,000 A falling acorn becomes a meteor. 9 00:00:49,600 --> 00:00:52,560 A tiny trickle, a tsunami. 10 00:00:55,960 --> 00:00:59,120 And every enemy, is a giant. 11 00:01:06,240 --> 00:01:08,680 Now, using the latest technology, 12 00:01:08,680 --> 00:01:12,160 we can recreate the world from their perspective - 13 00:01:14,720 --> 00:01:17,040 to experience it as they do. 14 00:01:22,880 --> 00:01:26,560 These are tales of life from the tropical jungle, 15 00:01:26,560 --> 00:01:29,360 and the northern forest 16 00:01:29,360 --> 00:01:32,120 in the Hidden Kingdoms. 17 00:01:58,400 --> 00:02:00,560 The ancient woods of North America. 18 00:02:04,360 --> 00:02:09,800 Hundred-year-old oaks cast their shadows over a hidden world. 19 00:02:22,760 --> 00:02:25,480 It's autumn. 20 00:02:28,880 --> 00:02:31,640 Time for the yearly fall of acorns. 21 00:02:44,880 --> 00:02:48,920 It's what every chipmunk in the forest has been waiting for. 22 00:02:58,560 --> 00:03:01,600 This youngster is only six weeks old, 23 00:03:01,600 --> 00:03:06,080 but will soon face the most important challenge of his life. 24 00:03:26,640 --> 00:03:30,040 For the smallest animals it's time to take cover. 25 00:03:34,720 --> 00:03:39,480 For chipmunks, it's time to get hoarding. 26 00:03:39,480 --> 00:03:42,000 Winter is on its way. 27 00:03:58,920 --> 00:04:02,040 A quick quality check, and the first nut goes in the bag. 28 00:04:57,960 --> 00:05:01,040 A chipmunk's tunnel may run for more than ten metres 29 00:05:01,040 --> 00:05:02,800 to keep its nuts safe. 30 00:05:07,400 --> 00:05:11,000 And they need a hoard of more than a hundred acorns to see them 31 00:05:11,000 --> 00:05:13,280 through the long winter ahead. 32 00:05:18,520 --> 00:05:22,160 For his first year, this youngster's done well. 33 00:05:23,480 --> 00:05:27,560 But a hoard is no use unless it's well hidden. 34 00:05:37,400 --> 00:05:39,920 He's being watched. 35 00:05:39,920 --> 00:05:45,320 This is an older chipmunk and sneakier too. 36 00:05:58,960 --> 00:06:03,520 Chipmunks are notorious thieves. 37 00:06:06,040 --> 00:06:10,080 After all, why work when you can steal from someone else? 38 00:06:35,280 --> 00:06:40,200 For the burglar it's a dash back to his burrow to stock his own hoard. 39 00:06:43,680 --> 00:06:48,600 Oblivious, the youngster gathers a last few "honest" nuts. 40 00:06:55,600 --> 00:06:59,520 The competition is about to get a whole lot bigger. 41 00:07:14,680 --> 00:07:16,680 A moose. 42 00:07:19,160 --> 00:07:21,320 It's hungry for nuts too. 43 00:07:31,120 --> 00:07:32,560 BELLOWING 44 00:07:32,560 --> 00:07:34,600 SQUEAKING 45 00:07:35,920 --> 00:07:40,480 This holdup is one he can't afford, especially 46 00:07:40,480 --> 00:07:42,520 when his store is being burgled. 47 00:08:06,000 --> 00:08:09,920 The young chipmunk is still held up. 48 00:08:13,560 --> 00:08:17,880 Every autumn a moose can eat enough acorns to put on 100 kilograms. 49 00:08:21,360 --> 00:08:25,600 Just what it needs to survive the harsh winter ahead. 50 00:08:29,160 --> 00:08:32,720 And that's the problem for small animals, they just can't 51 00:08:32,720 --> 00:08:34,720 store enough fat. 52 00:08:34,720 --> 00:08:38,200 It's why a larder of nuts is so important. 53 00:08:44,960 --> 00:08:47,720 He's about get a nasty surprise. 54 00:08:58,440 --> 00:09:00,800 His larder is now almost empty, 55 00:09:03,760 --> 00:09:06,480 and things are about to get worse. 56 00:09:16,120 --> 00:09:21,160 The burglar is back, and he's a seasoned fighter. 57 00:09:43,400 --> 00:09:48,160 An older, stronger chipmunk can kill a youngster. 58 00:10:01,560 --> 00:10:03,320 The youngster may have escaped, 59 00:10:03,320 --> 00:10:07,000 but no chipmunk can survive without a store of nuts. 60 00:10:08,520 --> 00:10:12,000 How will he make it through the coming winter? 61 00:10:25,040 --> 00:10:30,560 On the other side of the world is a forest where winter never comes. 62 00:10:34,320 --> 00:10:42,200 The steamy jungles of Borneo - a kingdom of perpetual heat. 63 00:10:44,760 --> 00:10:49,760 Concealed in the undergrowth are thousands of tiny creatures, 64 00:10:49,760 --> 00:10:51,640 more than anywhere else on earth. 65 00:10:59,080 --> 00:11:03,600 In this hidden kingdom competition is intense. 66 00:11:14,720 --> 00:11:17,840 So many different species battle for survival here. 67 00:11:20,400 --> 00:11:24,240 Each one must find its own place within this crowded world. 68 00:11:36,000 --> 00:11:43,960 Up in the canopy, lives one of the most curious creatures of them all. 69 00:11:49,320 --> 00:11:52,840 A tree shrew, 70 00:11:52,840 --> 00:11:57,000 a tiny mammal whose ancestors have lived in these jungles 71 00:11:57,000 --> 00:11:59,320 for more than 10 million years. 72 00:12:06,120 --> 00:12:07,120 BIRDS WHISTLE 73 00:12:10,360 --> 00:12:13,080 Nearby is a giant mangosteen tree 74 00:12:13,080 --> 00:12:16,160 that provides all the fruit she needs. 75 00:12:33,760 --> 00:12:38,600 Dinner is served, but it's a long way down. 76 00:12:47,960 --> 00:12:51,720 Luckily tree shrews are born acrobats. 77 00:13:45,960 --> 00:13:49,840 Tree shrews have the largest brain for their body size 78 00:13:49,840 --> 00:13:52,640 in the world and rarely make a mistake. 79 00:13:55,680 --> 00:13:58,560 They also have the most demanding metabolism - 80 00:13:58,560 --> 00:14:01,840 they need food every two hours. 81 00:14:01,840 --> 00:14:05,480 Even if it means leaving the safety of the treetops to find it. 82 00:14:10,840 --> 00:14:14,360 There's no one else around and she has the fruit all to herself. 83 00:14:15,720 --> 00:14:18,600 For now. 84 00:14:28,960 --> 00:14:31,720 Darkness brings a change to the forest. 85 00:14:41,720 --> 00:14:44,880 Only the toughest creatures venture out, 86 00:14:44,880 --> 00:14:47,640 with their very effective weapons. 87 00:14:51,080 --> 00:14:56,200 Thousands of vicious quills on a porcupine's back means he'll 88 00:14:56,200 --> 00:14:58,320 be left to eat in peace. 89 00:15:12,400 --> 00:15:17,360 At night, the best place for a tree shrew is safe up in the nest. 90 00:15:20,920 --> 00:15:23,720 Until now the forest has provided well. 91 00:15:27,280 --> 00:15:30,720 But she's yet to learn how fickle the rainforest can be. 92 00:15:38,240 --> 00:15:45,160 Morning, and like every tree shrew she wakes up hungry. 93 00:15:53,880 --> 00:15:56,640 Someone's up before her. 94 00:15:58,800 --> 00:16:02,160 And they're heading right for the great tree. 95 00:16:11,960 --> 00:16:15,320 Orang-utans are 500 times her size. 96 00:16:18,840 --> 00:16:24,760 They are fruit-eating machines and can strip a tree bare in no time. 97 00:16:47,520 --> 00:16:51,440 They're not the only ones attracted to fruit-bearing trees. 98 00:16:54,960 --> 00:16:58,680 The hungry will come from far and wide. 99 00:16:58,680 --> 00:17:02,280 GRUNTING 100 00:17:15,640 --> 00:17:19,680 If she's going to get her breakfast she'd better hurry. 101 00:17:58,920 --> 00:18:03,000 Forest giants have got there first. 102 00:18:11,000 --> 00:18:13,560 Weighing more than a man, 103 00:18:13,560 --> 00:18:17,000 these bearded pigs are as aggressive as they are greedy. 104 00:18:45,480 --> 00:18:48,280 Unluckily for the shrew, 105 00:18:48,280 --> 00:18:51,600 pigs have the most sensitive noses in the forest. 106 00:18:56,280 --> 00:18:59,920 Nothing escapes their attention. 107 00:18:59,920 --> 00:19:02,800 GRUNTING AND SNORTING 108 00:19:21,760 --> 00:19:23,720 SNORTING ECHOES 109 00:19:37,200 --> 00:19:39,680 Breakfast is disappearing. 110 00:19:48,880 --> 00:19:53,360 To eat again means finding another fruiting tree and fast. 111 00:20:00,800 --> 00:20:02,640 But in the rainforest, 112 00:20:02,640 --> 00:20:06,320 trees in fruit are actually few and far between. 113 00:20:10,440 --> 00:20:14,320 This young tree shrew must leave her home 114 00:20:14,320 --> 00:20:17,080 and search deep into the jungle. 115 00:20:29,080 --> 00:20:32,520 She will need all her wits to survive. 116 00:20:50,040 --> 00:20:54,920 In the hidden kingdom of the northern woods, it's leaves, 117 00:20:54,920 --> 00:20:57,760 not acorns, that are falling now. 118 00:21:01,480 --> 00:21:05,160 Winter is just a breath away. 119 00:21:32,080 --> 00:21:36,760 Small animals are already hunkering down for winter. 120 00:21:36,760 --> 00:21:42,960 A wood frog buries itself, soon to become a living block of ice. 121 00:21:47,240 --> 00:21:50,680 Once the freeze sets in, 122 00:21:50,680 --> 00:21:54,560 this chipmunk won't last long without a store of nuts. 123 00:22:03,760 --> 00:22:08,520 Facing an empty larder this late in the season means a chipmunk 124 00:22:08,520 --> 00:22:11,480 is forced to forage in enemy territory. 125 00:22:20,160 --> 00:22:21,840 Spotted. 126 00:22:29,760 --> 00:22:32,680 No neighbour will tolerate an intruder. 127 00:22:36,680 --> 00:22:38,920 Not where nuts are concerned. 128 00:22:40,040 --> 00:22:42,680 CHIPMUNKS CHITTER 129 00:22:56,440 --> 00:22:58,360 THUD OF ACORN 130 00:22:59,800 --> 00:23:01,840 THUDDING 131 00:23:03,680 --> 00:23:06,960 That sound is irresistible. 132 00:23:25,440 --> 00:23:29,760 There's a reason why chipmunks don't gather nuts from here. 133 00:23:45,560 --> 00:23:48,800 This is the home of a silent killer. 134 00:23:54,360 --> 00:23:56,120 A horned owl. 135 00:24:04,520 --> 00:24:11,760 Owls sleep during the day, so he might just get away with it. 136 00:24:38,400 --> 00:24:43,120 So far, so good, but he still needs lots more nuts. 137 00:24:51,560 --> 00:24:57,640 The days are getting shorter and once it's dark, 138 00:24:57,640 --> 00:25:00,280 it's a very different proposition. 139 00:25:24,040 --> 00:25:26,920 CHIPMUNK SQUEAKS 140 00:25:32,480 --> 00:25:34,840 OWL HOOTS 141 00:25:39,240 --> 00:25:42,400 Owls have extremely sensitive hearing. 142 00:26:06,760 --> 00:26:08,200 Time to go. 143 00:26:40,840 --> 00:26:42,680 SQUEAKING 144 00:27:10,920 --> 00:27:18,920 Speed may have saved him, but his larder is still half empty. 145 00:27:25,800 --> 00:27:29,800 And even worse, the first frost of winter is upon him. 146 00:27:31,880 --> 00:27:34,880 Chipmunks can't survive outside in the cold. 147 00:28:11,560 --> 00:28:13,800 THUNDER RUMBLES 148 00:28:26,880 --> 00:28:29,000 Back in the rainforest, 149 00:28:29,000 --> 00:28:31,840 the tree-shrew's supply of fruit has run dry. 150 00:28:41,240 --> 00:28:44,960 She needs an alternative source of food... 151 00:28:44,960 --> 00:28:46,920 THUNDER CLAP 152 00:28:46,920 --> 00:28:50,120 And there's the daily shower to contend with. 153 00:29:03,640 --> 00:29:08,000 When you're this small, raindrops are like water bombs. 154 00:29:50,120 --> 00:29:52,440 BIRDS TWEET 155 00:29:56,520 --> 00:29:59,200 She must make up for lost time. 156 00:30:11,640 --> 00:30:15,120 Down on the forest floor, 157 00:30:15,120 --> 00:30:18,320 dangers lurk around every corner. 158 00:30:31,320 --> 00:30:33,320 Fire ants. 159 00:30:35,040 --> 00:30:36,960 They sting with acid. 160 00:30:39,400 --> 00:30:45,800 Not to be disturbed, unless you're armour plated. 161 00:31:15,080 --> 00:31:20,640 A pangolin has claws as strong as a bear's and eats fire ants for lunch. 162 00:31:53,400 --> 00:31:57,040 She's drawn by the scent of something tasty. 163 00:32:01,600 --> 00:32:03,640 Pitcher plants are carnivorous, 164 00:32:03,640 --> 00:32:07,120 known for luring insects to a watery grave. 165 00:32:11,320 --> 00:32:14,120 This one lures hungry tree shrews. 166 00:32:17,920 --> 00:32:21,880 The inside of the lid is covered in a sweet secretion. 167 00:32:30,440 --> 00:32:33,360 STOMACH RUMBLES 168 00:32:45,040 --> 00:32:49,520 But the liquid is a laxative, 169 00:32:49,520 --> 00:32:52,160 and a fast acting one. 170 00:32:59,880 --> 00:33:04,640 The pitcher was after nutrients in the tree shrew's dung. 171 00:33:07,240 --> 00:33:12,040 It means she is now running on empty. 172 00:33:12,040 --> 00:33:15,720 And worse, she's not alone. 173 00:33:26,040 --> 00:33:28,280 A reticulated python. 174 00:33:52,640 --> 00:33:56,680 Instinct sends her up to the canopy. 175 00:33:56,680 --> 00:34:00,200 No snake can climb as fast as this. 176 00:34:02,320 --> 00:34:05,040 But nightfall is approaching. 177 00:34:05,040 --> 00:34:08,640 Night is no time for a tree shrew to be up and about. 178 00:34:13,640 --> 00:34:16,520 You never know who you might bump into. 179 00:34:23,400 --> 00:34:28,800 Twice her size, flying foxes are the largest bats in the world. 180 00:34:30,000 --> 00:34:33,480 They're able to fly from one fruit tree to another. 181 00:34:40,880 --> 00:34:46,120 More than half the creatures of the jungle are nocturnal, 182 00:34:46,120 --> 00:34:51,320 but for a daytime creature, night in the rainforest is an alien world. 183 00:35:01,800 --> 00:35:04,360 Strange fungi light the way. 184 00:35:06,120 --> 00:35:09,800 Why they glow is one of nature's mysteries. 185 00:35:41,560 --> 00:35:43,720 Their light doesn't travel far. 186 00:35:45,280 --> 00:35:47,680 It's almost pitch dark. 187 00:36:04,920 --> 00:36:07,360 CHIRRUPING 188 00:36:16,560 --> 00:36:21,480 These tarsiers are only ten centimetres tall. 189 00:36:29,080 --> 00:36:30,880 They're hunting. 190 00:36:54,280 --> 00:36:59,080 Nothing escapes their huge eyes and acute hearing. 191 00:36:59,080 --> 00:37:02,240 Not even the stealthiest predator in the forest. 192 00:37:18,560 --> 00:37:21,480 This python is also an expert night hunter. 193 00:37:21,480 --> 00:37:25,560 It has heat-sensing pits on the side of its face and can follow 194 00:37:25,560 --> 00:37:30,040 the heat trail of a warm blooded mammal, even in the dark. 195 00:37:50,680 --> 00:37:56,440 In the wild woods, dawn melts away the first ground frost. 196 00:37:58,120 --> 00:37:59,680 But it was a warning. 197 00:38:28,160 --> 00:38:32,000 Finding his stolen nuts and getting them back 198 00:38:32,000 --> 00:38:35,360 is now the youngster's only chance. 199 00:38:49,520 --> 00:38:51,680 The nut thief is going out. 200 00:39:09,680 --> 00:39:11,960 The youngster will have to be quick. 201 00:39:23,600 --> 00:39:25,440 Caught in the act. 202 00:39:48,680

00:41:43,760 --> 00:41:50,320 The youngster had better hurry, winter is here. 210 00:42:07,120 --> 00:42:12,440 Back in the jungle, the young tree shrew is weak with hunger, 211 00:42:14,240 --> 00:42:19,280 and is being pursued by the most relentless predator in the forest. 212 00:42:28,440 --> 00:42:30,080 She's driven higher. 213 00:43:03,200 --> 00:43:04,840 Another snake. 214 00:43:23,560 --> 00:43:25,400 Cornered. 215 00:43:27,320 --> 00:43:29,640 There's only one way out... 216 00:43:33,240 --> 00:43:36,560 But it's further than she's ever jumped before. 217 00:43:42,360

at last, a fruiting tree. 221 00:45:09,040 --> 00:45:11,880 For today, the adventure is over. 222 00:45:13,680 --> 00:45:17,440 But soon, her search will begin again. 223 00:45:38,440 --> 00:45:42,960 With each day that passes, this clever little creature will grow a 224 00:45:42,960 --> 00:45:47,920 little wiser and better able to cope with the danger that comes her way. 225 00:45:53,880 --> 00:45:57,440 In the Hidden Kingdom, life never slows down. 226 00:46:02,840 --> 00:46:08,720 Except perhaps in the temperate forest, when the big freeze sets in. 227 00:46:46,880 --> 00:46:51,680 Although for many animals this is a time of hardship, 228 00:46:51,680 --> 00:46:56,360 for a chipmunk, it's a chance to take a well-deserved rest. 229 00:46:58,800 --> 00:47:03,280 The start of six months of peaceful sleep. 230 00:47:08,720 --> 00:47:14,080 And when he gets hungry he'll wake, briefly and his nuts will be there. 231 00:47:17,400 --> 00:47:20,560 They'll last him all the way until spring, 232 00:47:20,560 --> 00:47:23,560 when he'll re-emerge, ready to begin again. 233 00:47:30,880 --> 00:47:34,760 Few little creatures survive their first months, 234 00:47:34,760 --> 00:47:38,960 but for those that do, what they have learned should make life become 235 00:47:38,960 --> 00:47:44,520 just that little bit easier, in the hidden kingdoms of the forests. 236 00:48:07,680 --> 00:48:09,680 Traditional natural history is 237 00:48:09,680 --> 00:48:12,520 filmed from a distance behind a telephoto lens. 238 00:48:14,760 --> 00:48:17,400 Hidden Kingdom is different. 239 00:48:17,400 --> 00:48:20,400 One of the biggest challenges filming Hidden Kingdom 240 00:48:20,400 --> 00:48:22,920 is trying to get down to the animal's eyeline and 241 00:48:22,920 --> 00:48:26,400 really portray the world that they see and the world that they live in. 242 00:48:26,400 --> 00:48:29,880 To see the world through the eyes of our tiny creatures 243 00:48:29,880 --> 00:48:33,680 meant getting our lenses as low to the ground as possible. 244 00:48:33,680 --> 00:48:37,320 Getting a camera to sit right on the forest floor 245 00:48:37,320 --> 00:48:41,600 at this sort of height is really tricky. 246 00:48:41,600 --> 00:48:42,920 Oops! 247 00:48:42,920 --> 00:48:44,440 HE LAUGHS 248 00:48:44,440 --> 00:48:47,280 It's amazing what difference an inch makes. 249
