18 00:01:38,697 --> 00:01:43,102 When it comes to causing mayhem, monkeys are the experts. 19 00:01:44,835 --> 00:01:47,804 In India, a troop of 30 rhesus macaques 20 00:01:47,872 --> 00:01:50,174 have commandeered an old water trough 21 00:01:50,241 --> 00:01:53,111 to use as their personal diving pool. 22 00:01:57,646 --> 00:01:59,716 And the bigger the splash... 23 00:02:01,684 --> 00:02:03,586 The greater the fun. 24 00:02:05,186 --> 00:02:08,022 Spy baby macaque is perfectly poised 25 00:02:08,090 --> 00:02:11,426 to record just how mischievous they really are. 26 00:02:22,537 --> 00:02:24,471 It seems like pandemonium, 27 00:02:25,138 --> 00:02:29,809 everyone does their own thing in their own particular style. 28 00:02:37,182 --> 00:02:38,984 Even the nervous. 29 00:02:45,822 --> 00:02:49,962 It's all about having fun and soaking as many mates as possible. 30 00:02:59,402 --> 00:03:02,238 Spy macaque attracts suspicion 31 00:03:02,806 --> 00:03:06,743 but manages to escape relatively unscathed. 32 00:03:10,512 --> 00:03:14,549 But, for a real baby, a pool without rules can be frightening. 33 00:03:24,223 --> 00:03:27,026 The mother is wise to be protective, 34 00:03:27,226 --> 00:03:30,596 but perhaps things aren't quite as anarchic as they seem. 35 00:03:32,464 --> 00:03:36,935 Splash a grown-up and you suffer the consequences. 36 00:03:44,176 --> 00:03:49,413 Soak the wrong kid and his angry mother soon puts you in your place. 37 00:03:53,250 --> 00:03:56,787 It looks more serious than it is, but that's the point. 38 00:04:00,824 --> 00:04:04,994 He won't do that again in a hurry. 39 00:04:05,060 --> 00:04:09,265 Despite appearances, macaque society is highly structured. 40 00:04:09,431 --> 00:04:11,132 Everyone knows their place. 41 00:04:12,400 --> 00:04:16,571 A lull in the chaos gives the chance for a swimming lesson... 42 00:04:21,974 --> 00:04:24,945 An anxious moment for any doting mother. 43 00:04:26,178 --> 00:04:29,749 She hovers over him, giving constant reassurance. 44 00:04:32,485 --> 00:04:36,823 It's just the encouragement he needs as he tries out his first strokes. 45 00:04:50,600 --> 00:04:52,202 He'll need plenty of practise. 46 00:04:52,269 --> 00:04:55,740 Experienced macaques can swim half a mile, 47 00:04:56,240 --> 00:04:57,941 but he's off to a good start. 48 00:04:59,775 --> 00:05:01,845 But what about the high dive?

It can release a team of spy dung balls 73 00:07:53,396 --> 00:07:56,066 to litter the savannah with yet more cameras. 74 00:08:01,671 --> 00:08:04,240 One dung ball is radio-controlled 75 00:08:04,306 --> 00:08:07,542 and can travel without any visible moving parts. 76 00:08:19,452 --> 00:08:21,722 With the action covered from every angle, 77 00:08:21,989 --> 00:08:25,058 it's time to see what this elephant family gets up to. 78 00:08:27,060 --> 00:08:31,064 The babies must learn the rules of behaviour at an early age. 79 00:08:36,168 --> 00:08:39,772 Wrestling older siblings is a favourite pastime. 80 00:08:43,975 --> 00:08:46,577 They learn their own strength and, crucially, 81 00:08:46,644 --> 00:08:48,846 how to play nicely with each other. 82 00:08:52,283 --> 00:08:55,953 It's the older elephants who make sure they don't cross the line. 83 00:08:59,388 --> 00:09:02,959 It takes a few years before they're big enough to do real damage. 84 00:09:06,762 --> 00:09:10,500 But as they get older, they need to be reined in. 85 00:09:10,565 --> 00:09:13,367 Those who overstep the mark soon know it. 86 00:09:14,535 --> 00:09:18,740 The rules are strict for everyone when the family is on the move. 87 00:09:19,274 --> 00:09:24,812 To follow them, spy egret and dung cam join forces. 88 00:09:27,212 --> 00:09:30,415 For their own safety, the babies must stay next to their mothers 89 00:09:30,482 --> 00:09:32,051 in the centre of the herd. 90 00:09:33,886 --> 00:09:36,121 The elephants are heading to the swamp... 91 00:09:41,759 --> 00:09:44,862 A place to cool off as the day heats up. 92 00:09:49,666 --> 00:09:51,435 But the mud can be treacherous 93 00:09:51,868 --> 00:09:54,704 and babies must only enter with their mums. 94 00:09:55,772 --> 00:09:58,607 But this little one seems to have forgotten the rules. 95 00:09:59,642 --> 00:10:02,078 Chasing egrets is irresistible. 96 00:10:04,179 --> 00:10:09,919 But as the herd enter the swamp, the baby is being left behind. 97 00:10:12,353 --> 00:10:15,589 Realising his predicament, he looks for his mother 98 00:10:16,124 --> 00:10:18,192 and thinks he's found her. 99 00:10:23,863 --> 00:10:26,800 He tags along as the group head into the swamp, 100 00:10:28,234 --> 00:10:30,970 but he's following the wrong elephant. 101 00:10:35,440 --> 00:10:39,077 With his mother nowhere to be seen, he's lost in a confusion 102 00:10:39,143 --> 00:10:40,779 of trunks and legs. 103 00:10:49,319 --> 00:10:52,021 The elephants head into the swamp without him. 104 00:10:52,989 --> 00:10:55,526 The baby is now alone and afraid... 105 00:11:01,230 --> 00:11:04,567 While his herd appear to have forgotten him. 106 00:11:12,873 --> 00:11:15,676 He can smell that his mother is out there... 107 00:11:16,311 --> 00:11:17,744 Somewhere. 108 00:11:27,987 --> 00:11:31,757 But entering the swamp alone could be deadly for one so small. 109 00:11:38,929 --> 00:11:41,000 He's really starting to panic now. 110 00:11:48,505 --> 00:11:50,741 His mother is inexperienced. 111 00:11:50,808 --> 00:11:53,211 She's only just realised her mistake. 112 00:12:01,051 --> 00:12:03,553 Both will have learnt from what happened. 113 00:12:08,223 --> 00:12:11,627 He won't misbehave while the family are travelling again... 114 00:12:17,264 --> 00:12:21,168 And stays extra close as he's taken into the swamp. 115 00:12:27,140 --> 00:12:30,976 He's learnt the hard way why you don't go here on your own. 116 00:12:33,613 --> 00:12:35,948 His older brother heads up the rear. 117 00:12:36,916 --> 00:12:40,084 No one is letting this mischievous baby out of their sight. 118 00:12:51,094 --> 00:12:54,498 Now the mud bathing can begin in earnest. 119 00:12:59,302 --> 00:13:02,973 But the cheeky elephants have a message for spy egret. 120 00:13:11,312 --> 00:13:15,616 Learning to behave is even more vital in extreme environments. 121 00:13:17,584 --> 00:13:23,358 In the Canadian Arctic, it is a matter of survival. 122 00:13:23,423 --> 00:13:25,657 Arctic wolf packs live in a society 123 00:13:25,724 --> 00:13:28,661 based on close cooperation and teamwork. 124 00:13:32,065 --> 00:13:35,367 Spy wolf cub is here to record how the cubs 125 00:13:35,434 --> 00:13:37,870 learn their place in the pack. 126 00:13:43,473 --> 00:13:46,143 He's been accepted as part of the family. 127 00:13:48,847 --> 00:13:52,448 They are now confident enough to wander away from the den. 128 00:13:54,585 --> 00:13:57,388 They love to play and are equally matched. 129 00:14:02,258 --> 00:14:06,729 For now, they can safely test each other's strengths and weaknesses. 130 00:14:09,096 --> 00:14:13,000 But their rough and tumble has woken the babysitter. 131 00:14:20,808 --> 00:14:22,576 She may have been sleeping on the job, 132 00:14:22,642 --> 00:14:26,146 but she's responsible for the cubs while their mother is away. 133 00:14:27,914 --> 00:14:32,785 She has strict rules and one is, stay close to the den. 134 00:14:34,520 --> 00:14:36,389 It's time they were taught a lesson. 135 00:14:45,364 --> 00:14:49,367 But this wolf cub isn't showing the respect the occasion demands. 136 00:14:51,002 --> 00:14:53,671 He's not supposed to answer back. 137 00:14:59,441 --> 00:15:01,243 She tries to roll him on his back, 138 00:15:01,310 --> 00:15:04,579 this is how wolves show they know their place. 139 00:15:08,317 --> 00:15:10,786 But the message isn't getting through. 140 00:15:12,219 --> 00:15:14,721 If he doesn't learn to submit by rolling over, 141 00:15:14,789 --> 00:15:16,890 he'll never fit in with the pack. 142 00:15:20,495 --> 00:15:22,796 But he's still arguing back. 143 00:15:26,734 --> 00:15:30,269 Now, she really gets tough, pinning him to the ground. 144 00:15:35,074 --> 00:15:37,777 She won't give up until he understands. 145 00:15:44,415 --> 00:15:46,617 He's got the message now. 146 00:15:56,059 --> 00:15:59,529 Learning to submit helps avoid conflict within the pack, 147 00:15:59,962 --> 00:16:02,798 vital for animals that must work together. 148 00:16:04,900 --> 00:16:09,304 Lesson over, they now practise what they learnt on each other. 149 00:16:20,781 --> 00:16:24,685 It seems even spy cub must learn the pack rules... 150 00:16:33,191 --> 00:16:36,328 But he soon makes a dignified recovery. 151 00:16:40,866 --> 00:16:43,468 The father howls a rallying call. 152 00:16:47,671 --> 00:16:52,410 The call is not to hunt, but to come and play in the cotton grass. 153 00:16:58,148 --> 00:17:02,785 With the rules firmly established, playtime becomes a family affair... 154 00:17:06,688 --> 00:17:09,391 A chance for the mischievous cubs to let off steam 155 00:17:09,457 --> 00:17:12,860 and learn the value of teamwork and cooperation. 156 00:17:32,278 --> 00:17:35,548 While animals that live together must learn the rules, 157 00:17:35,847 --> 00:17:38,816 for others, it's everyone for themselves. 158 00:17:41,219 --> 00:17:44,757 Frigate birds are the original pirates of the Caribbean. 159 00:17:47,825 --> 00:17:52,095 They make a living on the high seas from skulduggery and thievery. 160 00:17:55,700 --> 00:17:59,436 Fishing boats returning with their catch make easy targets. 161 00:18:21,722 --> 00:18:25,325 Fish cams reveal the details of their criminal activity. 162 00:18:50,247 --> 00:18:54,852 Tropicbirds returning to feed their young carry yet more riches. 163 00:18:59,557 --> 00:19:02,158 A fleet of frigates follow in hot pursuit. 164 00:19:02,724 --> 00:19:05,528 They know she carries a fish hidden in her throat 165 00:19:05,862 --> 00:19:08,297 and it's one they won't let get away. 166 00:19:12,467 --> 00:19:14,936 Their technique is sheer intimidation, 167 00:19:15,169 --> 00:19:17,839 forcing the tropicbird to give up its meal. 168 00:19:23,876 --> 00:19:27,379 To gain a bird's-eye view of their nefarious ways, 169 00:19:27,613 --> 00:19:30,950 spy tropicbird braves the intimidation. 170 00:19:43,428 --> 00:19:45,295 He faces skilled assailants. 171 00:19:45,362 --> 00:19:49,600 Their slender wings and curved tails allow swift manoeuvring. 172 00:19:55,105 --> 00:19:58,108 It allows them to wait until the perfect moment. 173 00:20:08,550 --> 00:20:11,820 Real tropicbirds make more challenging targets. 174 00:20:13,221 --> 00:20:15,623 And when the frigates really put on the pressure, 175 00:20:16,057 --> 00:20:18,393 it's safer to give up without a fight. 176 00:20:20,862 --> 00:20:24,064 Show resistance and you pay the price. 177 00:20:26,398 --> 00:20:28,834 They'll shake the fish right out of you. 178 00:20:35,674 --> 00:20:37,076 There's a lot at stake. 179 00:20:37,277 --> 00:20:38,778 Fish are hard to come by, 180 00:20:38,845 --> 00:20:41,479 give it up and her young might starve. 181 00:20:43,547 --> 00:20:45,816 But these villains even work together, 182 00:20:47,117 --> 00:20:50,687 so taking the path of least resistance is tempting. 183 00:20:55,458 --> 00:20:57,994 They won't give up until they've had their fill. 184 00:21:02,398 --> 00:21:04,601 But these birds aren't here to kill. 185 00:21:07,535 --> 00:21:11,005 So, to succeed, you just have to tough it out. 186 00:21:12,408 --> 00:21:14,909 Her hungry chick drives her on. 187 00:21:20,180 --> 00:21:24,384 She's made it and her chick finally gets a meal. 188 00:21:28,320 --> 00:21:31,690 It's not just tropicbirds that are subjected to bad behaviour 189 00:21:31,758 --> 00:21:33,727 from feathered felons. 190 00:21:47,437 --> 00:21:51,775 In Antarctica, spy penguin is greeting Adelie penguins 191 00:21:51,843 --> 00:21:54,177 as they return from a two-week fishing trip 192 00:21:54,243 --> 00:21:56,079 away from their nest sites. 193 00:22:01,717 --> 00:22:03,619 He receives the same bolshie reception 194 00:22:03,685 --> 00:22:05,754 as the penguins give to each other. 195 00:22:11,026 --> 00:22:15,161 Despite their belligerent nature, they are dedicated parents 196 00:22:15,228 --> 00:22:18,967 and are rushing home to relieve their partners of nesting duties. 197 00:22:19,566 --> 00:22:23,703 The birds breed on a rocky outcrop high above the sea ice. 198 00:22:25,573 --> 00:22:27,141 Another spy penguin is filming 199 00:22:27,208 --> 00:22:30,176 the disorderly behaviour inside the colony. 200 00:22:33,345 --> 00:22:36,248 The Adelies constantly squabble over the stones 201 00:22:36,314 --> 00:22:37,882 they use to build their nests. 202 00:22:43,921 --> 00:22:46,556 Spy Adelie is in the thick of this rabble 203 00:22:46,624 --> 00:22:49,327 as everyone steals from everyone else. 204 00:23:05,507 --> 00:23:07,409 He may be an innocent bystander, 205 00:23:07,710 --> 00:23:09,845 but that doesn't stop him getting picked on. 206 00:23:13,713 --> 00:23:16,350 Although he's designed to get right up again. 207 00:23:19,052 --> 00:23:22,055 In case it all gets too much, he has backup, 208 00:23:22,589 --> 00:23:24,424 the other spy penguin. 209 00:23:27,059 --> 00:23:29,863 This one comes with a pebble cam. 210 00:23:36,134 --> 00:23:38,703 Egg cams are here as well... 211 00:23:39,638 --> 00:23:42,441 But they, too, get the same rough treatment. 212 00:23:49,814 --> 00:23:52,015 Here, weather changes quickly 213 00:23:52,483 --> 00:23:55,886 and it soon dampens the high spirits of the colony. 214 00:24:02,391 --> 00:24:06,763 Now their only concern is to protect their eggs from the storm, 215 00:24:07,130 --> 00:24:08,996 so everyone hunkers down. 216 00:24:12,000 --> 00:24:14,869 Spy penguin is the only one still on duty, 217 00:24:15,603 --> 00:24:19,773 except for a straggler racing back from his fishing trip. 218 00:24:25,111 --> 00:24:29,180 Stuck on her nest for the last two weeks, his mate is hungry. 219 00:24:29,514 --> 00:24:32,384 But she'll have to stay put till the storm passes. 220 00:24:35,620 --> 00:24:38,456 Meanwhile, he has a plan to impress her... 221 00:24:40,192 --> 00:24:44,562 Use the cover of the storm to steal more stones. 222 00:24:47,765 --> 00:24:50,769 It gets easier as the blizzard gets stronger. 223 00:24:53,403 --> 00:24:58,040 Blinded by the snow storm, they become easy victims of crime. 224 00:25:38,244 --> 00:25:39,910 By the time the storm ends, 225 00:25:39,976 --> 00:25:43,381 they have one of the finest nests in the colony. 226 00:25:48,452 --> 00:25:51,088 The petty pilfering of stones is one thing, 227 00:25:51,589 --> 00:25:54,625 but a much greater crime is about to be committed. 228 00:25:56,593 --> 00:25:59,428 Better weather brings in predators. 229 00:26:03,532 --> 00:26:05,700 These are skuas. 230 00:26:05,768 --> 00:26:08,571 Their speciality is stealing eggs. 231 00:26:15,242 --> 00:26:17,278 Each Adelie has only two eggs 232 00:26:17,545 --> 00:26:20,515 and a year's investment goes into rearing them. 233 00:26:22,249 --> 00:26:26,253 But with skuas on the prowl, one can go in a flash. 234 00:26:42,132 --> 00:26:44,870 But not all eggs are quite what they seem. 235 00:26:47,004 --> 00:26:50,308 Egg cam is about to reveal what it's like to be kidnapped. 236 00:27:16,297 --> 00:27:21,402 Realising it's not the real thing, egg cam is discarded in disgust. 237 00:27:31,310 --> 00:27:34,481 Adelies may be pugnacious and dishonest, 238 00:27:35,581 --> 00:27:37,916 but they are devoted to their young. 239 00:27:43,288 --> 00:27:47,691 Each chick that makes it is a triumph against the real criminals. 240 00:27:49,559 --> 00:27:51,328 The whole process of breeding 241 00:27:51,395 --> 00:27:53,463 brings out the best and the worst 242 00:27:53,529 --> 00:27:54,797 in some birds. 243 00:27:59,168 --> 00:28:03,406 The rainforests of eastern Australia are the stage for perhaps 244 00:28:03,472 --> 00:28:05,941 the sneakiest criminals of the lot. 245 00:28:11,647 --> 00:28:14,248 This is the satin bowerbird, 246 00:28:14,716 --> 00:28:17,686 a creature with a bad case of kleptomania. 247 00:28:19,719 --> 00:28:23,389 He is under surveillance from a female spy bowerbird 248 00:28:23,456 --> 00:28:25,825 with a particularly beady eye. 249 00:28:28,660 --> 00:28:31,363 He builds this elaborate cradle, or bower, 250 00:28:31,430 --> 00:28:33,865 to show off his prowess and skills. 251 00:28:41,739 --> 00:28:43,975 It doesn't stop at weaving twigs, 252 00:28:44,309 --> 00:28:46,744 he likes home decor, too. 253 00:28:49,980 --> 00:28:52,082 Blue is his favourite colour. 254 00:28:52,515 --> 00:28:55,284 Bottle tops nicked from a nearby campsite 255 00:28:55,452 --> 00:28:57,488 are his proudest possession. 256 00:29:02,258 --> 00:29:04,027 He has an eye for detail, too, 257 00:29:04,193 --> 00:29:07,528 placing them precisely for maximum visual impact. 258 00:29:09,763 --> 00:29:13,634 Stage set, it's time to begin his performance. 259 00:29:21,875 --> 00:29:27,346 But he soon realises spy bowerbird is immune to his charm. 260 00:29:29,015 --> 00:29:32,451 Perhaps he'll have better luck with a real bowerbird. 261 00:29:36,287 --> 00:29:37,890 She makes all the right moves, 262 00:29:37,957 --> 00:29:40,458 entering the bower to show she's interested. 263 00:29:41,693 --> 00:29:44,028 A ring makes the perfect gift. 264 00:29:50,001 --> 00:29:51,536 Not impressed? 265 00:29:54,603 --> 00:29:56,539 How about a bouquet of flowers? 266 00:30:06,514 --> 00:30:09,051 But something is not quite right. 267 00:30:10,385 --> 00:30:11,720 The penny drops, 268 00:30:12,119 --> 00:30:13,621 he's been duped! 269 00:30:15,189 --> 00:30:20,193 This isn't a female at all, it's a young male in disguise 270 00:30:20,426 --> 00:30:22,629 and he's here to steal. 271 00:30:24,763 --> 00:30:27,133 He's part of a gang of juvenile delinquents 272 00:30:27,200 --> 00:30:30,936 roaming the forest, tricking unwary males. 273 00:30:32,070 --> 00:30:37,175 In their hideout, they disply their ill-gotten gains. 274 00:30:38,239 --> 00:30:41,578 It takes up to seven years for a male bowerbird to reach maturity. 275 00:30:41,645 --> 00:30:45,015 In the meantime, they practise making a bower 276 00:30:45,083 --> 00:30:46,984 and dancing for each other. 277 00:30:48,920 --> 00:30:52,690 But they can never have too many blue trinkets and bling. 278 00:30:54,491 --> 00:30:56,425 Time to go out stealing again. 279 00:30:59,061 --> 00:31:03,467 And bowers don't come more decadently inviting than this. 280 00:31:05,333 --> 00:31:07,268 But this is no ordinary bower, 281 00:31:07,835 --> 00:31:11,472 it's occupied by a male spy bowerbird and adorned 282 00:31:11,540 --> 00:31:16,711 with an irresistible array of blue treasure and jewel cameras, 283 00:31:16,777 --> 00:31:20,781 all perfectly placed to catch the thieves in the act. 284 00:31:30,924 --> 00:31:34,327 Like professionals, they approach with caution. 285 00:31:36,360 --> 00:31:39,631 Once again, they pretend to be courting females. 286 00:31:41,800 --> 00:31:44,201 This time they work together. 287 00:31:44,601 --> 00:31:48,038 One distracts as the other steals the jewels. 288 00:31:49,907 --> 00:31:54,176 Spy bowerbird can only observe as they clean out the bower, 289 00:31:54,376 --> 00:31:56,680 gem by precious gem. 290 00:32:03,719 --> 00:32:05,621 Back home with their stolen goods, 291 00:32:05,688 --> 00:32:08,556 they continue to practise their courtship techniques. 292 00:32:10,959 --> 00:32:13,961 But spy bowerbird isn't off the hook. 293 00:32:18,498 --> 00:32:21,535 The male bowerbird who was their first victim 294 00:32:21,601 --> 00:32:23,937 needs to replenish his bower. 295 00:32:24,638 --> 00:32:28,308 Well, if you can't beat them, you may as well join them. 296 00:32:38,082 --> 00:32:41,620 In Senegal, the art of seduction brings out the worst 297 00:32:41,687 --> 00:32:44,290 in our closest animal relatives. 298 00:32:52,029 --> 00:32:55,766 For young chimps, misbehaving is second nature. 299 00:32:59,167 --> 00:33:03,406 They're cut a lot of slack and generally do exactly what they want. 300 00:33:08,444 --> 00:33:11,413 But as they get older, they start to push their luck 301 00:33:11,479 --> 00:33:13,481 and wind the adults up. 302 00:33:21,622 --> 00:33:26,460 It starts small, but often escalates. 303 00:33:26,526 --> 00:33:29,430 Spy tortoise is just one of the many spy cameras 304 00:33:29,495 --> 00:33:31,029 that have been watching them. 305 00:33:37,469 --> 00:33:40,973 He's been capturing some very unconventional views. 306 00:33:49,979 --> 00:33:53,718 But now he's helping record how the bad behaviour of the youngsters 307 00:33:53,784 --> 00:33:56,754 translates into adulthood. 308 00:33:57,387 --> 00:34:01,658 In chimp society, there are always a few dominant males. 309 00:34:03,324 --> 00:34:05,227 As a young male reaches adulthood, 310 00:34:05,294 --> 00:34:08,564 he becomes a potential challenger for the top spot. 311 00:34:08,930 --> 00:34:13,101 The lead male must keep this cocky upstart in his place. 312 00:34:16,404 --> 00:34:19,873 And the other males are keen to teach him a lesson, too. 313 00:34:25,044 --> 00:34:28,482 He needs to get away or suffer serious injury. 314 00:34:33,886 --> 00:34:36,589 He may not be popular with the bigger guys... 315 00:34:39,824 --> 00:34:42,860 But among the females, it's a different matter. 316 00:34:52,802 --> 00:34:56,005 It seems many prefer the younger male. 317 00:35:02,578 --> 00:35:05,047 She seems to be giving him the come-on, 318 00:35:05,480 --> 00:35:08,417 but he must be careful he isn't seen. 319 00:35:10,885 --> 00:35:14,556 Fortunately, chimps like their midday nap... 320 00:35:22,763 --> 00:35:26,334 And the female encourages him to follow her. 321 00:35:41,279 --> 00:35:43,482 It could be his lucky day. 322 00:35:48,017 --> 00:35:49,920 One last check. 323 00:35:57,226 --> 00:36:00,262 Time for a little extra privacy. 324 00:36:03,866 --> 00:36:08,370 Unfortunately, one male has the perfect vantage point. 325 00:36:15,043 --> 00:36:16,578 Spotted! 326 00:36:17,878 --> 00:36:20,815 This is strictly against the rules. 327 00:36:31,956 --> 00:36:35,862 His fun ruined, he leaves in disgrace. 328 00:36:37,662 --> 00:36:40,799 But once he's cooled off, he'll be back. 329 00:36:45,535 --> 00:36:47,871 In the Kalahari Desert in South Africa, 330 00:36:48,372 --> 00:36:49,839 there are dire consequences 331 00:36:49,905 --> 00:36:52,543 for those who have illicit affairs. 332 00:36:57,213 --> 00:36:59,748 Meerkats live in large family groups 333 00:36:59,982 --> 00:37:02,786 and there is equality among most of the members. 334 00:37:06,556 --> 00:37:08,823 But with so many meerkats living together, 335 00:37:09,122 --> 00:37:12,427 clear leadership is needed to maintain authority. 336 00:37:15,062 --> 00:37:16,862 This female is in charge. 337 00:37:17,230 --> 00:37:18,732 Often called the queen, 338 00:37:18,799 --> 00:37:22,302 she is the only female to breed in the entire colony. 339 00:37:23,337 --> 00:37:27,973 Spy meerkat is ideally placed to film any rule breakers. 340 00:37:29,876 --> 00:37:31,511 Sentinels watch for danger 341 00:37:31,577 --> 00:37:33,979 so that the rest of the colony can socialise. 342 00:37:35,847 --> 00:37:38,851 Play helps youngsters practise fighting skills 343 00:37:38,918 --> 00:37:40,050 they'll need in the future 344 00:37:40,250 --> 00:37:43,254 and makes sure they're all supportive of the colony. 345 00:37:47,991 --> 00:37:50,861 The queen meerkat asserts her higher position 346 00:37:50,928 --> 00:37:53,931 by hip slamming and chin swiping. 347 00:37:58,835 --> 00:38:02,571 She doesn't want the youngsters to get ideas above their station. 348 00:38:06,375 --> 00:38:11,046 Constant reminders of who's boss help to maintain a stable society. 349 00:38:13,880 --> 00:38:17,218 But sometimes the balance of power is challenged. 350 00:38:20,620 --> 00:38:23,155 A roving male from outside the colony 351 00:38:23,223 --> 00:38:24,891 is on the lookout for a female... 352 00:38:26,259 --> 00:38:30,463 One that has reached maturity and is up for some excitement. 353 00:38:31,930 --> 00:38:35,568 She sneaks off for an illicit encounter. 354 00:38:37,903 --> 00:38:39,136 Away from the group, 355 00:38:39,203 --> 00:38:41,739 she's free to express her desire. 356 00:38:51,147 --> 00:38:54,218 Her flirtations are strictly taboo. 357 00:38:54,551 --> 00:38:57,253 Only the queen has breeding rights. 358 00:39:08,263 --> 00:39:10,332 But she's been caught in the act. 359 00:39:14,069 --> 00:39:16,204 The queen launches an attack. 360 00:39:19,507 --> 00:39:21,709 The rest of the group show their support. 361 00:39:26,812 --> 00:39:30,917 A female that tries to breed is a threat to the status quo. 362 00:39:33,786 --> 00:39:36,488 Rule breakers are not to be tolerated. 363 00:39:40,860 --> 00:39:43,361 They must evict her from the colony. 364 00:39:57,173 --> 00:39:59,242 Resistance is pointless. 365 00:40:01,743 --> 00:40:04,746 But, alone, she's in great danger. 366 00:40:14,387 --> 00:40:19,426 And expelled to the edges of the colony, there is no easy way back. 367 00:40:24,031 --> 00:40:27,365 The nearest meerkats are hostile neighbours. 368 00:40:27,932 --> 00:40:31,437 Her indiscretion has put her life at risk. 369 00:40:41,413 --> 00:40:43,215 Off the coast of South Africa, 370 00:40:43,514 --> 00:40:47,017 more adolescents have reached that difficult age. 371 00:40:48,352 --> 00:40:51,020 At two years old, male bottlenose dolphins 372 00:40:51,087 --> 00:40:54,925 leave their mother's pod to form boisterous gangs 373 00:40:54,990 --> 00:40:56,525 looking for excitement. 374 00:40:56,592 --> 00:41:00,128 They like nothing better than surfing. 375 00:41:00,195 --> 00:41:03,498 Spy turtle is here to see what they get up to. 376 00:41:13,675 --> 00:41:16,910 He, in turn, is joined by another spy creature. 377 00:41:21,815 --> 00:41:25,952 This is spy puffer, based on a fish that blows itself into 378 00:41:26,018 --> 00:41:27,654 a defensive puffball. 379 00:41:30,890 --> 00:41:34,894 The spy creatures are here to film these teenage tearaways. 380 00:41:39,164 --> 00:41:41,866 Spy puffer faces a bumpy ride. 381 00:41:46,371 --> 00:41:48,440 Bust-ups are common. 382 00:41:53,176 --> 00:41:55,112 It's easy to get caught in the middle. 383 00:41:59,315 --> 00:42:00,817 The young males are so unruly 384 00:42:00,884 --> 00:42:03,686 the females kicked them out of the family pod. 385 00:42:21,668 --> 00:42:24,404 They even send spy turtle in a spin. 386 00:42:32,779 --> 00:42:36,348 This isn't spy puffer, it's a real pufferfish. 387 00:42:37,950 --> 00:42:40,920 The poor creature gets the same rough treatment. 388 00:42:51,295 --> 00:42:53,297 Perfect for a game of catch. 389 00:43:00,736 --> 00:43:03,406 But the dolphins are dicing with death. 390 00:43:05,206 --> 00:43:09,677 Pufferfish are one of the most poisonous fish in the ocean. 391 00:43:10,278 --> 00:43:14,782 They exude a powerful nerve poison called tetrodotoxin. 392 00:43:15,749 --> 00:43:18,519 It only takes a small amout to kill a human. 393 00:43:22,621 --> 00:43:27,794 Even so, the dolphins often look for pufferfish and love to chew on them. 394 00:43:29,928 --> 00:43:31,497 Taken in small doses, 395 00:43:31,564 --> 00:43:34,634 the secretions seem to have a narcotic effect. 396 00:43:45,610 --> 00:43:48,279 The dolphins are careful not to swallow them. 397 00:43:48,345 --> 00:43:51,616 Instead, they hold them gently in their mouths. 398 00:43:53,984 --> 00:43:55,551 Despite the risks, 399 00:43:55,617 --> 00:43:58,854 passing the puffer has become a popular dolphin pastime. 400 00:44:26,312 --> 00:44:31,150 Luckily, the little fishes usually survive the strange experience. 401 00:44:41,592 --> 00:44:43,360 But dolphins aren't the only creatures 402 00:44:43,427 --> 00:44:46,230 that seem to enjoy natural highs. 403 00:44:50,033 --> 00:44:54,237 In Madagascar, brown and black lemurs have an equally odd weakness 404 00:44:54,303 --> 00:44:56,639 for mind-altering chemicals. 405 00:45:02,645 --> 00:45:06,481 Their favourite poison is found crawling in the forest. 406 00:45:08,350 --> 00:45:11,653 Like pufferfish, millipedes are toxic. 407 00:45:13,955 --> 00:45:17,258 But that doesn't stop the lemurs seeking them out. 408 00:45:26,565 --> 00:45:30,536 The millipedes use dangerous secretions, including cyanide, 409 00:45:30,703 --> 00:45:32,205 as a defence. 410 00:45:36,307 --> 00:45:38,276 But the lemurs still chew on them, 411 00:45:38,343 --> 00:45:40,679 albeit extremely cautiously. 412 00:45:46,384 --> 00:45:49,454 The toxins cause the lemurs to salivate. 413 00:45:52,255 --> 00:45:56,860 They then rub both the saliva and the millipede into their fur. 414 00:45:57,660 --> 00:46:00,696 They use it as an insecticide to ward off insects, 415 00:46:00,764 --> 00:46:03,665 such as mosquitoes that carry malaria. 416 00:46:04,833 --> 00:46:07,302 But they are suspiciously enthusiastic 417 00:46:07,369 --> 00:46:09,272 about the whole process. 418 00:46:17,178 --> 00:46:21,282 It seems they don't just work as an insect repellent... 419 00:46:24,750 --> 00:46:29,122 The chemicals also appear to send them into a trance-like state. 420 00:46:39,530 --> 00:46:43,434 A condition of complete intoxication. 421 00:46:59,682 --> 00:47:01,718 And they can't seem to get enough. 422 00:47:18,465 --> 00:47:22,436 When it's all over, there's no hiding the state they're in. 423 00:47:26,471 --> 00:47:29,109 Time to sleep it off. 424 00:47:39,151 --> 00:47:41,086 Back in the Kalahari Desert 425 00:47:41,153 --> 00:47:43,320 and spy meerkat is on the lookout 426 00:47:43,387 --> 00:47:45,223 for the evicted female. 427 00:47:50,094 --> 00:47:51,828 She's still all alone. 428 00:47:55,165 --> 00:47:56,834 Pushed to the edge of her territory, 429 00:47:57,100 --> 00:48:00,136 she's an easy target for the hostile neighbours. 430 00:48:05,440 --> 00:48:08,310 A bolt-hole offers refuge from the threat. 431 00:48:13,680 --> 00:48:17,518 These meerkats are hoping to steal some territory from her family, 432 00:48:18,018 --> 00:48:20,820 but she won't be able to fight them off by herself. 433 00:48:23,856 --> 00:48:26,793 The unruly mob try to dig their way in. 434 00:48:31,830 --> 00:48:35,200 They work as a team to shift as much sand as possible. 435 00:48:44,108 --> 00:48:45,709 Others leave their scent mark, 436 00:48:45,777 --> 00:48:48,646 laying claim to their new territory. 437 00:48:56,619 --> 00:48:58,921 She defends the bolthole with her life. 438 00:49:03,759 --> 00:49:07,063 But the marauding trespassers have been spotted. 439 00:49:09,398 --> 00:49:11,500 The group rally together. 440 00:49:19,573 --> 00:49:23,744 Tails held high, they perform an intimidating war dance. 441 00:49:40,657 --> 00:49:43,527 The rival gang clocks the incoming attack. 442 00:49:47,498 --> 00:49:50,468 It's designed as a show of strength and unity... 443 00:49:53,536 --> 00:49:55,906 But the mob meets the attack head on. 444 00:50:00,608 --> 00:50:02,612 It's a fight for territory. 445 00:50:15,589 --> 00:50:19,326 But ultimately, the land grab fails. 446 00:50:23,664 --> 00:50:25,866 The female checks for the all clear. 447 00:50:32,270 --> 00:50:34,872 Her family drove the intruders away 448 00:50:35,205 --> 00:50:36,874 but she played her part. 449 00:50:37,975 --> 00:50:41,914 This is her opportunity to show her loyalty and subservience. 450 00:50:44,213 --> 00:50:46,717 She grooms the dominant female. 451 00:50:48,820 --> 00:50:51,856 The eviction was a harsh lesson in how to behave. 452 00:50:55,658 --> 00:50:58,561 Her apparent contrition does the trick, 453 00:50:59,229 --> 00:51:02,097 the queen meerkat accepts her back. 454 00:51:04,967 --> 00:51:07,603 But warfare doesn't just happen between groups, 455 00:51:08,070 --> 00:51:11,739 sometimes the battles begin at the heart of the family. 456 00:51:12,506 --> 00:51:15,375 The male chimpanzee that took his chance with a female 457 00:51:15,442 --> 00:51:17,312 is in a confident mood. 458 00:51:18,712 --> 00:51:21,614 He wants to flex his muscles within the troop. 459 00:51:22,615 --> 00:51:26,186 Spy bushbaby is watching to see what unfolds. 460 00:51:28,055 --> 00:51:31,356 The young male is pumped up and spoiling for a fight. 461 00:51:32,091 --> 00:51:35,761 Standing on two legs makes a more threatening display. 462 00:52:09,791 --> 00:52:13,229 To really act the tough guy, he needs a weapon. 463 00:52:19,533 --> 00:52:22,636 But this theatrical show has gone on long enough. 464 00:52:22,769 --> 00:52:25,504 The big males decide to take him on. 465 00:52:41,219 --> 00:52:43,287 The mothers gather up the youngsters. 466 00:52:43,354 --> 00:52:44,723 It's turning ugly. 467 00:53:12,913 --> 00:53:16,083 One dominant male makes his entrance. 468 00:53:18,586 --> 00:53:21,789 Time to put a stop to this outrageous behaviour. 469 00:53:23,756 --> 00:53:25,325 The two square up. 470 00:53:32,864 --> 00:53:36,135 But no one does scary like the high-ranking male. 471 00:53:49,280 --> 00:53:51,416 First a show of his strength. 472 00:53:56,986 --> 00:54:01,325 Then he selects his own weapon and the conflict escalates. 473 00:54:19,038 --> 00:54:20,341 He means business, 474 00:54:20,440 --> 00:54:23,476 these stones are thrown with deadly accuracy. 475 00:54:29,215 --> 00:54:31,316 Time to make his escape. 476 00:54:39,457 --> 00:54:43,095 Defeated, the challenger vents his frustration. 477 00:54:47,899 --> 00:54:51,235 From the winner, a final show of his power. 478 00:54:53,871 --> 00:54:59,175 These may be raw emotions, but anger soon gives way to subtler feelings. 479 00:55:01,944 --> 00:55:05,214 A youngster reaches out a hand of friendship. 480 00:55:08,916 --> 00:55:12,286 Placed in the mouth, it's the ultimate show of trust. 481 00:55:14,288 --> 00:55:17,057 An act of faith and reassurance... 482 00:55:18,993 --> 00:55:21,095 And a gesture the others mirror. 483 00:55:23,930 --> 00:55:28,768 Chimps may be quick to anger, but fun is never far away. 484 00:55:31,970 --> 00:55:33,172 For the little males, 485 00:55:33,239 --> 00:55:35,640 mischief is part of their psyche. 486 00:55:35,707 --> 00:55:39,310 It prepares them for family life in a rowdy troop 487 00:55:39,910 --> 00:55:44,081 where rules and consequences control their lives. 488 00:55:45,416 --> 00:55:48,586 For now, they can just enjoy their freedom. 489 00:55:52,355 --> 00:55:55,826 Spy bushbaby has revealed an eye-opening insight 490 00:55:55,891 --> 00:55:58,328 into chimp family politics... 491 00:55:59,763 --> 00:56:02,731 And survived to spy another day. 492 00:56:04,099 --> 00:56:06,001 Wherever the spy creatures went, 493 00:56:06,068 --> 00:56:07,570 they gave unexpected insights 494 00:56:07,637 --> 00:56:10,237 into the intimate lives of animals. 495 00:56:13,373 --> 00:56:18,245 Emotions were explored when langurs grieved over a dropped spy monkey... 496 00:56:20,847 --> 00:56:23,684 And a chimp adopted an abandoned kitten. 497 00:56:26,986 --> 00:56:30,288 Their extraordinary intelligence was revealed by an orang-utan 498 00:56:30,355 --> 00:56:32,391 who took to DIY... 499 00:56:35,393 --> 00:56:38,763 And a bird who created a perfect fishing pole. 500 00:56:40,231 --> 00:56:42,433 Friendships were tested by spy cobra, 501 00:56:42,499 --> 00:56:46,102 who captured the solidarity of meerkat society. 502 00:56:48,137 --> 00:56:51,741 Spy croc filmed some tiny birds who formed a bond 503 00:56:51,809 --> 00:56:54,211 with the unlikeliest of neighbours. 504 00:56:56,344 --> 00:56:59,848 Finally, the spy creatures showed how bad behaviour 505 00:56:59,915 --> 00:57:03,687 is as much part of animals' lives as it is of our own. 506 00:57:10,124 --> 00:57:11,626 Maybe what they really revealed 507 00:57:11,693 --> 00:57:14,062 is that animals are more like us 508 00:57:14,295 --> 00:57:16,698 than we ever dared to believe. 509 00:57:18,399 --> 00:57:21,435 Next time, we reveal the cutting-edge technology 510 00:57:21,502 --> 00:57:23,903 and extraordinary science behind the series 511 00:57:23,970 --> 00:57:26,573 as it stretches the camera teams to their limits 512 00:57:26,673 --> 00:57:29,776 and tests some spy creatures to destruction.
