1 00:00:21,563 --> 00:00:24,963 After two nights alone in the South African bush… 2 00:00:27,283 --> 00:00:31,323 the little lion cubs are finally reunited with their mother. 3 00:00:39,003 --> 00:00:42,083 But their sister Kaya is still missing. 4 00:00:54,603 --> 00:00:57,243 More careful than her brothers, 5 00:00:57,803 --> 00:01:00,723 this clever little cub has been hiding, 6 00:01:01,283 --> 00:01:04,923 waiting to ensure the coast is clear. 7 00:01:29,363 --> 00:01:32,723 But this moment of tenderness must be brief. 8 00:01:36,763 --> 00:01:39,243 With a strong scent of leopard in the area, 9 00:01:40,483 --> 00:01:43,003 mom has to keep her cubs moving. 10 00:01:45,803 --> 00:01:48,603 Their survival depends on it. 11 00:02:01,003 --> 00:02:04,483 Babies born wild must often be on the move. 12 00:02:06,723 --> 00:02:08,483 They need to find food, 13 00:02:09,043 --> 00:02:10,163 seek safety, 14 00:02:12,123 --> 00:02:13,963 or simply move home. 15 00:02:22,163 --> 00:02:26,363 Kaya and her brothers are on their way to a new den site. 16 00:02:29,363 --> 00:02:33,283 Each new hideout will keep them safe from their enemies. 17 00:02:36,683 --> 00:02:39,563 But traveling by day is risky. 18 00:02:42,163 --> 00:02:44,603 They need to stay close to their mom. 19 00:02:47,763 --> 00:02:52,403 Until now, their world has been restricted to a little rocky outcrop. 20 00:02:55,563 --> 00:02:59,843 So the journey is an eye-opener to their African home. 21 00:03:14,483 --> 00:03:20,363 Kaya gets her first real view of the MalaMala Pride Lands. 22 00:03:22,523 --> 00:03:25,163 And the neighbors she'll share them with. 23 00:03:37,523 --> 00:03:40,883 But this guinea fowl is not quite as pleased to see Kaya. 24 00:03:52,883 --> 00:03:58,243 The little cub doesn't yet understand she's Africa's top-ranking predator… 25 00:03:59,963 --> 00:04:02,483 …and everyone's afraid of them. 26 00:04:16,523 --> 00:04:17,963 It's been a long walk. 27 00:04:19,643 --> 00:04:20,923 And being the smallest… 28 00:04:23,483 --> 00:04:26,203 Kaya's feeling tired and hungry. 29 00:04:28,443 --> 00:04:30,563 She's beginning to lag behind. 30 00:04:36,323 --> 00:04:37,923 There's only one thing for it. 31 00:04:46,363 --> 00:04:49,803 It's tough as a single mom traveling with kids. 32 00:05:04,563 --> 00:05:07,243 Suddenly, out in the grasslands… 33 00:05:09,123 --> 00:05:10,523 …there's a familiar call. 34 00:05:23,883 --> 00:05:25,283 The cubs keep low. 35 00:05:28,003 --> 00:05:30,323 Any strange lion is a threat. 36 00:05:43,323 --> 00:05:45,003 But she's one of the family. 37 00:05:45,763 --> 00:05:47,763 Mom's younger sister. 38 00:05:51,763 --> 00:05:55,043 Lionesses are the heart and soul of the pride. 39 00:05:57,843 --> 00:05:59,963 They form lifelong attachments 40 00:06:00,043 --> 00:06:03,443 and share the duties of bringing up the cubs. 41 00:06:05,283 --> 00:06:07,723 In this first meeting with their aunt, 42 00:06:07,803 --> 00:06:10,883 straightaway, the bond is clear. 43 00:06:15,203 --> 00:06:19,163 Now, they have help to get to their new den site. 44 00:06:20,723 --> 00:06:23,403 It's close to the shores of the Sand River. 45 00:06:26,323 --> 00:06:30,083 Stretching for 15 miles through the center of their territory, 46 00:06:30,923 --> 00:06:35,243 this river is the lifeblood of the MalaMala pride. 47 00:06:37,123 --> 00:06:43,083 Its precious water is a magnet for the animals that lions like to hunt. 48 00:06:49,523 --> 00:06:52,203 Mom hasn't made a kill in days. 49 00:06:53,323 --> 00:06:56,083 But now, with backup from her sister, 50 00:06:56,723 --> 00:06:58,683 she might have more success. 51 00:07:02,363 --> 00:07:06,043 Unless she eats soon, her cubs won't make it. 52 00:07:10,203 --> 00:07:13,963 Together, they hide the cubs in the shelter of the bushes 53 00:07:14,043 --> 00:07:17,883 and set off on a vitally important hunting trip. 54 00:07:24,843 --> 00:07:29,083 Newborns usually need time to grow strong enough to travel. 55 00:07:30,563 --> 00:07:36,163 But some babies face a journey from the very first moment of birth. 56 00:07:38,683 --> 00:07:41,723 The tropical coast of Central America. 57 00:07:49,003 --> 00:07:54,083 For thousands of sea creatures, it marks the start of a journey. 58 00:07:57,203 --> 00:08:00,083 These are olive ridley turtles. 59 00:08:01,763 --> 00:08:04,523 Every one, an expectant mother. 60 00:08:08,883 --> 00:08:11,603 They've swum a whole ocean to get here. 61 00:08:16,243 --> 00:08:18,963 To the beach where their lives began. 62 00:08:25,523 --> 00:08:28,203 Each year, they come back to nest. 63 00:08:31,723 --> 00:08:34,963 And produce the next generation of sea turtles. 64 00:08:42,403 --> 00:08:46,683 It's known as the arribada, or arrival. 65 00:08:55,523 --> 00:08:57,643 Over just a few days, 66 00:08:58,763 --> 00:09:01,603 millions of eggs will be buried here. 67 00:09:20,723 --> 00:09:24,003 This mom is one of the last to arrive. 68 00:09:25,763 --> 00:09:29,203 She heads to the back of the beach, beyond the tide line… 69 00:09:31,283 --> 00:09:35,323 where her clutch of 100 eggs will be safe from the waves. 70 00:09:42,283 --> 00:09:44,363 With her babies all tucked in, 71 00:09:45,043 --> 00:09:46,403 it's time to leave. 72 00:09:53,203 --> 00:09:56,083 But her mission hasn't gone unnoticed. 73 00:10:01,003 --> 00:10:04,163 A hunter is stalking the sands. 74 00:10:07,843 --> 00:10:08,963 A jaguar. 75 00:10:16,403 --> 00:10:18,603 With his own forest home shrinking, 76 00:10:19,443 --> 00:10:22,203 he's been forced to hunt further afield. 77 00:10:28,403 --> 00:10:32,843 He's discovered there's food to be found on the beach. 78 00:10:38,483 --> 00:10:40,323 If mom can reach the surf, 79 00:10:41,523 --> 00:10:43,363 she might just make it. 80 00:11:04,363 --> 00:11:05,283 Coming here, 81 00:11:06,443 --> 00:11:09,923 she's paid the ultimate sacrifice a mother can make 82 00:11:10,803 --> 00:11:13,523 for the offspring she'll never meet. 83 00:11:19,803 --> 00:11:21,523 But in a matter of weeks… 84 00:11:25,963 --> 00:11:28,243 her story will be continued. 85 00:11:44,883 --> 00:11:48,723 Being on the move doesn't always involve a journey. 86 00:11:50,883 --> 00:11:54,683 Sometimes, it's about taking those first tentative steps 87 00:11:54,763 --> 00:11:56,523 towards independence. 88 00:12:01,323 --> 00:12:05,283 This is Indonesia's dense tropical jungle. 89 00:12:11,683 --> 00:12:14,803 Up in the canopy, 70 feet high, 90 00:12:15,803 --> 00:12:16,923 an orangutan. 91 00:12:20,403 --> 00:12:22,723 A mother with her tiny baby. 92 00:12:26,283 --> 00:12:29,363 Few have a stronger bond in the animal world. 93 00:12:37,283 --> 00:12:40,523 Mina, her daughter, is just a few months old. 94 00:12:42,763 --> 00:12:45,403 She's been clinging to her mom since birth. 95 00:12:46,843 --> 00:12:49,763 Using her body as a climbing frame… 96 00:12:53,323 --> 00:12:54,283 …to feed… 97 00:12:57,363 --> 00:12:59,243 even to sleep. 98 00:13:07,083 --> 00:13:11,323 But now, Mina's at the age when she wants more freedom. 99 00:13:16,163 --> 00:13:20,923 After all, in the jungle, there's a lot to explore. 100 00:13:24,523 --> 00:13:28,443 A sheer variety of animals and plants. 101 00:13:37,923 --> 00:13:40,523 But which trees are safe to climb? 102 00:13:45,163 --> 00:13:46,443 What's on the menu? 103 00:13:47,643 --> 00:13:48,523 And where? 104 00:13:50,123 --> 00:13:53,843 That's why every minute of her first seven years 105 00:13:53,923 --> 00:13:55,683 will be spent with mom. 106 00:13:59,803 --> 00:14:04,683 It'll take that long to acquire all her knowledge and wisdom. 107 00:14:17,843 --> 00:14:19,523 But Mina's got a problem. 108 00:14:27,283 --> 00:14:31,243 Her mom's first baby died suddenly in infancy. 109 00:14:34,163 --> 00:14:38,603 It seems the memory of her firstborn has left her fearful. 110 00:14:43,323 --> 00:14:46,243 Every attempt Mina makes to leave her side 111 00:14:47,763 --> 00:14:48,803 is thwarted. 112 00:14:55,843 --> 00:14:57,403 She's not allowed to climb. 113 00:15:00,643 --> 00:15:01,683 Or try things out. 114 00:15:05,963 --> 00:15:08,403 Even when they're tantalizingly close. 115 00:15:20,603 --> 00:15:23,963 This overprotectiveness is holding Mina back. 116 00:15:32,323 --> 00:15:35,243 But this baby is a bit of a rebel. 117 00:15:41,283 --> 00:15:46,003 Desperate for some freedom, she starts pushing against the boundaries. 118 00:16:00,043 --> 00:16:03,843 Her constant fidgeting wears her mother down. 119 00:16:08,123 --> 00:16:10,963 She never gives her a break. 120 00:16:15,483 --> 00:16:20,843 And, of course, there are downsides to keeping your baby this close. 121 00:16:37,603 --> 00:16:40,123 Mom's finally got the message. 122 00:16:51,803 --> 00:16:53,843 It's just a small win for Mina. 123 00:16:56,443 --> 00:16:58,403 Hardly the freedom of the forest. 124 00:17:03,563 --> 00:17:06,963 But it's a milestone for her mom. 125 00:17:11,683 --> 00:17:14,003 In letting Mina take her first steps… 126 00:17:16,963 --> 00:17:19,283 she's realized that part of being a good mom 127 00:17:21,363 --> 00:17:23,363 is letting your loved ones go. 128 00:17:41,243 --> 00:17:44,003 It's a warm, clear night in Costa Rica. 129 00:17:47,803 --> 00:17:50,483 And new life is stirring. 130 00:17:56,923 --> 00:17:58,603 Under cover of darkness, 131 00:17:58,683 --> 00:18:03,323 tiny olive ridley turtles crawl from their buried nests. 132 00:18:15,843 --> 00:18:20,323 Each of these baby hatchlings is driven by instinct, 133 00:18:20,403 --> 00:18:23,803 following the brightest horizon to reach the sea. 134 00:18:30,283 --> 00:18:33,603 There's just 70 feet of sand to cross. 135 00:18:37,563 --> 00:18:39,763 But if you're less than two inches long, 136 00:18:40,963 --> 00:18:43,003 that's a marathon. 137 00:18:49,043 --> 00:18:51,003 As thousands begin to emerge… 138 00:18:54,883 --> 00:18:58,163 the synchrony of the hatching becomes clear. 139 00:19:04,443 --> 00:19:08,483 This midnight flight has been widely anticipated. 140 00:19:16,243 --> 00:19:21,403 Predators have turned up to take advantage of a feast. 141 00:19:25,883 --> 00:19:28,403 Even an old enemy is back. 142 00:19:33,323 --> 00:19:35,483 Picked off one by one, 143 00:19:36,003 --> 00:19:38,363 thousands won't make it. 144 00:19:40,163 --> 00:19:42,323 But of those who run the gauntlet, 145 00:19:42,883 --> 00:19:47,723 some will get through to reach the safety of the sea. 146 00:19:55,843 --> 00:19:57,723 Up beyond the tide line, 147 00:19:58,363 --> 00:20:00,323 the last to emerge. 148 00:20:02,683 --> 00:20:07,283 The hatchlings have reached the surface of their late mother's nest. 149 00:20:09,843 --> 00:20:11,483 For this baby female, 150 00:20:12,443 --> 00:20:15,003 a first view of dawn. 151 00:20:23,323 --> 00:20:29,043 But now, in the clear light of day, it's the very worst time to run. 152 00:20:31,283 --> 00:20:32,843 With no one to guide her, 153 00:20:33,403 --> 00:20:36,483 the plucky hatchling makes her move. 154 00:20:42,763 --> 00:20:47,043 Tangled tree roots must seem like a mountain range 155 00:20:47,123 --> 00:20:48,803 to a tiny turtle. 156 00:20:53,883 --> 00:20:56,283 Her siblings find a way through. 157 00:21:05,323 --> 00:21:06,923 While with one tumble, 158 00:21:08,283 --> 00:21:09,683 she's a sitting target. 159 00:21:24,163 --> 00:21:26,203 But she's not done yet. 160 00:21:32,163 --> 00:21:34,003 It's a straight sprint ahead. 161 00:21:36,803 --> 00:21:38,123 But out in the open, 162 00:21:39,403 --> 00:21:40,843 there's nowhere to hide. 163 00:21:44,043 --> 00:21:46,443 Black vultures stalk the sands. 164 00:21:48,723 --> 00:21:49,923 And up above, 165 00:21:51,243 --> 00:21:53,963 frigate birds mount relentless attack. 166 00:22:04,363 --> 00:22:05,403 On this beach… 167 00:22:10,203 --> 00:22:13,003 …it seems there are a hundred ways to die. 168 00:22:21,843 --> 00:22:25,523 She's almost within striking distance of the surf. 169 00:22:28,043 --> 00:22:29,083 Now, 170 00:22:30,523 --> 00:22:32,203 it's all down to luck. 171 00:22:46,883 --> 00:22:49,083 Where her mother's journey ended… 172 00:22:51,723 --> 00:22:54,323 could hers be just beginning? 173 00:23:16,323 --> 00:23:17,963 In reaching the ocean, 174 00:23:18,043 --> 00:23:22,563 this baby turtle will spend the next 15 years at sea, 175 00:23:22,643 --> 00:23:24,763 before finding her way back 176 00:23:24,843 --> 00:23:29,083 to this same beach to lay her own eggs 177 00:23:29,163 --> 00:23:32,083 and continue her mother's legacy. 178 00:23:40,803 --> 00:23:45,323 With a new dawn in Southern Africa, comes excitement. 179 00:23:48,923 --> 00:23:53,163 Their mother has a tasty treat for Kaya and her brothers. 180 00:23:55,283 --> 00:23:59,283 During the night, she and her sister finally made a kill. 181 00:24:04,123 --> 00:24:09,043 Now she has the chance to give the cubs their first taste of meat. 182 00:24:12,603 --> 00:24:15,683 But to get there, they have to cross the Sand River. 183 00:24:21,403 --> 00:24:22,523 Like most cats… 184 00:24:24,483 --> 00:24:26,683 …Kaya's afraid of water. 185 00:24:33,403 --> 00:24:35,363 It's the darkness of it. 186 00:24:40,523 --> 00:24:44,803 The strange creatures lurking in the depths. 187 00:24:51,443 --> 00:24:55,163 It's not safe for little Kaya to attempt to swim. 188 00:25:01,723 --> 00:25:05,003 Whereas her big brothers must fend for themselves. 189 00:25:26,443 --> 00:25:29,443 The cub's aunt has been guarding the kill, 190 00:25:30,043 --> 00:25:32,243 waiting for their arrival. 191 00:25:37,643 --> 00:25:39,963 The brothers are the first to approach. 192 00:25:42,443 --> 00:25:44,483 They've never had solids before. 193 00:25:50,163 --> 00:25:51,523 They soon tuck in, 194 00:25:52,723 --> 00:25:55,883 while Kaya is typically wary. 195 00:26:02,683 --> 00:26:07,443 But there's something about that smell that's irresistible. 196 00:26:21,883 --> 00:26:24,563 This fresh meat, full of protein, 197 00:26:24,643 --> 00:26:27,603 will be a nutritious supplement to mom's milk. 198 00:26:30,443 --> 00:26:32,683 But they've got visitors. 199 00:26:38,203 --> 00:26:39,643 Hooded vultures. 200 00:26:45,123 --> 00:26:49,123 Scavengers, forever on the lookout for their next meal. 201 00:27:01,083 --> 00:27:03,923 The adults know this is very bad news. 202 00:27:07,883 --> 00:27:09,803 Because where there's one vulture… 203 00:27:13,323 --> 00:27:16,323 soon, there will be dozens. 204 00:27:20,963 --> 00:27:25,283 To any predator, circling vultures advertise a kill. 205 00:27:32,083 --> 00:27:33,843 And the MalaMala pride 206 00:27:35,043 --> 00:27:38,603 happen to be on patrol close by. 207 00:27:46,723 --> 00:27:50,003 Mom's unsure how they'll react to her cubs. 208 00:28:06,483 --> 00:28:09,123 But they're only interested in the carcass. 209 00:28:20,843 --> 00:28:22,363 As the pride rush in, 210 00:28:23,243 --> 00:28:25,803 these are the very worst circumstances 211 00:28:25,883 --> 00:28:28,283 for the cubs' first meeting with their family. 212 00:28:32,523 --> 00:28:37,923 Getting between a lion and food can be fatal for a vulnerable youngster. 213 00:28:44,043 --> 00:28:45,203 In all the commotion… 214 00:28:47,603 --> 00:28:50,283 …their mom loses her hard-won kill. 215 00:28:58,563 --> 00:28:59,563 But worst of all, 216 00:29:01,363 --> 00:29:02,683 as they run for cover, 217 00:29:03,723 --> 00:29:06,043 she loses sight of her cubs.
