1
00:00:10,920 --> 00:00:14,840
Looking down from two miles above the surface of the Earth

2
00:00:14,840 --> 00:00:17,320
it's impossible not to be impressed

3
00:00:17,320 --> 00:00:20,680
by the sheer grandeur and splendour

4
00:00:20,680 --> 00:00:23,080
and power of the natural world.

5
00:00:26,520 --> 00:00:30,000
Ten years ago, in a television series called Planet Earth,

6
00:00:30,000 --> 00:00:35,440
we revealed many of those wonders, but today, much has changed.

7
00:00:37,680 --> 00:00:41,840
We can now show life on our planet in entirely new ways.

8
00:00:44,240 --> 00:00:47,840
Bring you closer to animals than ever before.

9
00:00:50,880 --> 00:00:55,640
And reveal new wildlife dramas for the very first time.

10
00:00:59,240 --> 00:01:00,720
But that's not all.

11
00:01:01,840 --> 00:01:04,680
Our planet has changed too.

12
00:01:04,680 --> 00:01:08,920
Never have those wildernesses been as fragile and as precious

13
00:01:08,920 --> 00:01:10,440
as they are today.

14
00:01:13,600 --> 00:01:16,600
At this crucial time for the natural world,

15
00:01:16,600 --> 00:01:19,920
we will journey to every corner of the globe...

16
00:01:21,520 --> 00:01:24,480
..to explore the greatest treasures of our living planet...

17
00:01:31,360 --> 00:01:35,320
..and reveal the extreme lengths animals go to

18
00:01:35,320 --> 00:01:36,680
to survive.

19

20
00:01:51,280 --> 00:01:55,440
Finally, we will explore our cities

21
00:01:55,440 --> 00:01:57,960
to see how life is adapting

22
00:01:57,960 --> 00:02:00,120
to the newest habitat on Earth.

23
00:02:02,480 --> 00:02:05,200
This is Planet Earth II.

24
00:02:45,280 --> 00:02:49,400
There are hundreds of thousands of islands,

25
00:02:49,400 --> 00:02:53,040
each one a world in miniature,

26
00:02:53,040 --> 00:02:56,040
a microcosm of our living planet.

27
00:02:57,840 --> 00:03:01,080
The struggles to survive on these remote lands

28
00:03:01,080 --> 00:03:05,240
reflect the challenges faced by all life on Earth.

29
00:03:15,840 --> 00:03:20,400
The tiny island of Escudo off the coast of Panama.

30
00:03:22,160 --> 00:03:26,360
Home to the pygmy three-toed sloth.

31
00:03:29,600 --> 00:03:32,920
This is a male and life here suits him well.

32
00:03:36,440 --> 00:03:39,880
Mangroves provide all the leaves he can eat

33
00:03:39,880 --> 00:03:43,240
and there are no predators to worry him.

34
00:03:45,200 --> 00:03:50,200
Island life may seem idyllic but it comes at a price.

35
00:03:51,840 --> 00:03:55,440
There are only a few hundred pygmy sloths in existence.

36
00:03:56,880 --> 00:03:59,000
And he needs a mate.

37
00:04:00,560 --> 00:04:03,680
SCREECHING

38
00:04:03,680 --> 00:04:05,680
That's an enticing call...

39
00:04:07,760 --> 00:04:08,800
..from a female.

40
00:04:11,640 --> 00:04:13,960
Somewhere out there.

41
00:04:16,840 --> 00:04:21,000
And this, for a sloth, is a quick reaction.

42
00:04:41,560 --> 00:04:43,840
FEMALE SCREECHES AGAIN

43
00:04:43,840 --> 00:04:47,560
The problem is, there's deep water between them.

44
00:04:49,280 --> 00:04:52,520
So what should any red-blooded sloth do?

45
00:04:57,840 --> 00:04:59,560
Swim, of course.

46
00:05:29,960 --> 00:05:31,480
Could this be her?

47
00:05:38,600 --> 00:05:42,040
He does his best to put on a turn of speed.

48
00:05:52,680 --> 00:05:54,800
But she's not the one.

49
00:05:54,800 --> 00:05:59,920
She already has a baby and she won't mate again until it leaves her

50
00:05:59,920 --> 00:06:01,600
in about six months' time.

51
00:06:08,720 --> 00:06:13,120
Even life on a paradise island can have its limitations.

52
00:06:16,640 --> 00:06:17,680
MORE SCREECHING

53
00:06:18,920 --> 00:06:21,280
But at least she can't be far away.

54
00:06:26,800 --> 00:06:32,040
The world's entire population of pygmy sloths is isolated

55
00:06:32,040 --> 00:06:35,600
on a speck of land no bigger than New York's Central Park.

56
00:06:38,800 --> 00:06:43,360
The size of an island has a huge influence on the fate

57
00:06:43,360 --> 00:06:45,160
of those cast away there.

58
00:06:49,880 --> 00:06:53,680
The island of Komodo in Indonesia.

59
00:07:04,160 --> 00:07:06,240
Home to dragons.

60
00:07:23,560 --> 00:07:28,720
Ten feet long and weighing an impressive 150 lbs,

61
00:07:28,720 --> 00:07:33,160
these are the largest living lizards on the planet.

62
00:07:44,720 --> 00:07:47,960
It's unusual to find large predators on islands.

63
00:07:51,680 --> 00:07:56,600
Yet, for four million years, the Komodo dragon has dominated here.

64
00:08:06,560 --> 00:08:09,720
It might seem there wouldn't be enough food

65
00:08:09,720 --> 00:08:12,960
to support such giants on this relatively small island.

66
00:08:14,520 --> 00:08:17,120
But reptiles, being cold-blooded,

67
00:08:17,120 --> 00:08:21,160
need only about a tenth of the food a carnivorous mammal would.

68
00:08:25,760 --> 00:08:28,880
A single meal will last a dragon a month.

69
00:08:32,400 --> 00:08:36,720
There are so successful that their only serious competition comes from

70
00:08:36,720 --> 00:08:38,480
others of their own kind.

71
00:08:39,640 --> 00:08:42,800
And there are some 2,000 of them here.

72
00:09:05,800 --> 00:09:11,040
This giant, however, isn't looking for food - he's looking for a mate.

73
00:09:15,040 --> 00:09:18,760
Female dragons come into season only once a year.

74
00:09:29,160 --> 00:09:30,480
She's receptive.

75
00:09:38,560 --> 00:09:40,800
So far, so good.

76
00:09:45,240 --> 00:09:47,960
But he's strayed into someone else's patch.

77
00:09:53,680 --> 00:09:58,360
Another huge male thinks he is the king here.

78
00:10:03,000 --> 00:10:05,720
Space being limited on islands,

79
00:10:05,720 --> 00:10:10,720
dragon territories overlap and that creates continual conflict.

80
00:10:18,200 --> 00:10:21,480
In dragon society, size is everything.

81
00:10:36,680 --> 00:10:41,320
But if rivals are closely matched, the outcome can be uncertain.

82
00:10:48,720 --> 00:10:52,560
Muscular tails strike with the power of sledgehammers.

83
00:11:02,360 --> 00:11:06,600
And their serrated teeth are as sharp as steak knives.

84
00:11:18,000 --> 00:11:20,720
Each tries to topple his opponent.

85
00:11:41,760 --> 00:11:43,040
Defeated.

86
00:11:44,240 --> 00:11:47,080
Only the most powerful dragons

87
00:11:47,080 --> 00:11:48,720
win the right to mate.

88
00:11:57,120 --> 00:12:01,040
The limited food and space on small islands

89
00:12:01,040 --> 00:12:03,560
can often lead to intense competition.

90
00:12:04,760 --> 00:12:07,520
But some islands are immense.

91
00:12:08,600 --> 00:12:10,560
More like miniature continents.

92
00:12:11,880 --> 00:12:17,080
And these provide opportunities for life to experiment and evolve.

93
00:12:21,840 --> 00:12:27,320
Madagascar is one of the biggest islands and also one of the oldest,

94
00:12:27,320 --> 00:12:32,160
having split away from Africa over 120 million years ago.

95
00:12:43,200 --> 00:12:45,080
With time and isolation,

96
00:12:45,080 --> 00:12:50,080
its animals have adapted to take advantage of every available niche.

97
00:12:56,120 --> 00:13:01,400
The island now has some 250,000 different species,

98
00:13:01,400 --> 00:13:04,320
most found nowhere else on Earth.

99
00:13:16,640 --> 00:13:19,520
These are not monkeys, but lemurs.

100
00:13:25,160 --> 00:13:29,560
From a single ancestor, about 100 different types have evolved.

101
00:13:34,800 --> 00:13:38,920
The largest, the indri, seldom comes down from the branches.

102
00:13:46,080 --> 00:13:50,640
The much smaller ringtails wander in troops across the forest floor

103
00:13:50,640 --> 00:13:51,800
searching for food.

104
00:13:53,520 --> 00:13:57,720
And tiny bamboo lemurs eat nothing except bamboo.

105
00:14:05,520 --> 00:14:09,360
With few competitors, lemurs have been free to colonise

106
00:14:09,360 --> 00:14:12,000
almost every environment on the island.

107
00:14:14,560 --> 00:14:17,040
Even the most extreme.

108
00:14:24,560 --> 00:14:28,840
This baby sifaka has a hard life ahead of it.

109
00:14:33,480 --> 00:14:36,680
He's been born in the most arid and hostile corner

110
00:14:36,680 --> 00:14:39,160
of Madagascar's vast landscape.

111
00:14:41,960 --> 00:14:45,200
If he is to survive here, he has much to learn.

112
00:14:52,640 --> 00:14:54,960
The spiny forest is like a desert.

113
00:14:56,480 --> 00:15:01,240
It rarely rains, so water and food is very hard to find.

114
00:15:09,480 --> 00:15:12,640
Moving from tree to tree is a perilous business.

115
00:15:14,640 --> 00:15:18,680
Here, nearly all the plants are covered with ferocious spines.

116
00:15:20,840 --> 00:15:24,120
His mother searches the tree tops for the youngest leaves.

117
00:15:26,520 --> 00:15:30,280
They provide the only food and water to sustain the family.

118
00:15:36,760 --> 00:15:40,600
At three months old, the youngster is starting to explore.

119
00:15:46,320 --> 00:15:49,840
All too soon he will have to fend for himself up here.

120
00:15:55,520 --> 00:15:59,520
But it's altogether easier to stay on mother's back.

121
00:16:07,560 --> 00:16:10,600
If he can master the strange ways of this forest...

122
00:16:11,800 --> 00:16:14,720
..he will have a little corner of Madagascar to himself.

123
00:16:21,480 --> 00:16:24,960
Island life encourages animals to do things differently.

124
00:16:26,400 --> 00:16:29,400
And on some islands that is essential.

125
00:16:44,040 --> 00:16:46,440
There are islands still forming today...

126
00:16:47,800 --> 00:16:49,600
..built by volcanoes.

127
00:16:53,120 --> 00:16:55,000
Some erupt explosively.

128
00:17:02,040 --> 00:17:04,920
Others pour out rivers of molten rock.

129
00:17:06,040 --> 00:17:07,080
Lava.

130
00:17:13,400 --> 00:17:14,840
In the last 50 years,

131
00:17:14,840 --> 00:17:17,880
ten new volcanic islands have been formed.

132
00:17:45,080 --> 00:17:50,240
Newly created and often remote, they're hard for colonists to reach.

133
00:17:53,840 --> 00:17:57,920
Even those that do find these are tough places to survive.

134
00:18:03,840 --> 00:18:08,440
This is Fernandina, one of the Galapagos Islands in the Pacific.

135
00:18:10,800 --> 00:18:15,160
Young and still volcanically active, it's a desolate place.

136
00:18:29,600 --> 00:18:33,840
The surrounding sea, however, is particularly rich with life.

137
00:18:38,000 --> 00:18:42,720
And the frontier between these two very different worlds is the home of

138
00:18:42,720 --> 00:18:44,880
one of the strangest of reptiles.

139
00:18:49,640 --> 00:18:51,480
Seagoing iguanas.

140
00:18:54,400 --> 00:18:55,760
They are vegetarians,

141
00:18:55,760 --> 00:18:58,840
but since there's little food for them on the land,

142
00:18:58,840 --> 00:19:01,840
marine iguanas graze on the sea floor.

143
00:19:06,120 --> 00:19:09,040
A big male like this one can dive to 30 metres

144
00:19:09,040 --> 00:19:11,520
and hold his breath for half an hour.

145
00:19:37,520 --> 00:19:42,120
There are more than 7,000 individuals on Fernandina alone.

146
00:19:50,400 --> 00:19:53,360
And by bringing nutrients from the sea to the land,

147
00:19:53,360 --> 00:19:56,520
the iguanas help other animals to survive here, too.

148
00:20:00,480 --> 00:20:03,880
Crabs feed on dead skin on the iguana's back

149
00:20:03,880 --> 00:20:07,920
and, in turn, provide a welcome exfoliation service.

150
00:20:15,760 --> 00:20:19,680
While smaller lizards prey on the flies that pester the colony.

151
00:20:42,080 --> 00:20:46,520
But not all the relationships on this island are so harmonious.

152
00:20:53,120 --> 00:20:55,760
Marine iguanas lay their eggs in sand.

153
00:20:58,280 --> 00:21:02,240
In June, when the hatchlings emerge, they are vulnerable.

154
00:21:06,320 --> 00:21:09,800
They must join the adults at the edge of the sea.

155
00:21:09,800 --> 00:21:12,120
But the journey will be a dangerous one.

156
00:21:37,400 --> 00:21:38,840
Racer snakes.

157
00:22:08,520 --> 00:22:10,680
The snakes miss their chance.

158
00:22:18,960 --> 00:22:21,000
But more babies are hatching.

159
00:22:26,560 --> 00:22:29,320
And now the snakes are on the alert.

160
00:22:30,640 --> 00:22:34,680
This is the best feeding opportunity they will get all year.

161
00:22:50,360 --> 00:22:55,120
On flat ground, a baby iguana can outrun a racer snake.

162
00:22:56,880 --> 00:22:58,920
But others are waiting in ambush.

163
00:23:26,440 --> 00:23:30,960
Another hatchling has its first glimpse of a dangerous world.

164
00:24:28,920 --> 00:24:33,040
A snake's eyes aren't very good,

165
00:24:33,040 --> 00:24:34,760
but they can detect movement.

166
00:24:35,960 --> 00:24:40,600
So if the hatchling keeps its nerve, it may just avoid detection.

167
00:26:12,360 --> 00:26:14,240
A near miraculous escape.

168
00:26:21,360 --> 00:26:25,280
The lucky survivors can begin learning the unique way of life

169
00:26:25,280 --> 00:26:27,920
demanded by this hostile island.

170
00:26:36,720 --> 00:26:39,760
Although marine iguanas are expert swimmers,

171
00:26:39,760 --> 00:26:41,760
they can't cross open oceans.

172
00:26:50,960 --> 00:26:55,200
But even the stormiest waters are no barrier for birds.

173
00:27:05,040 --> 00:27:10,160
Gale force winds and cold temperatures make the sub-Antarctic

174
00:27:10,160 --> 00:27:13,920
islands off New Zealand particularly unwelcoming in winter.

175
00:27:26,920 --> 00:27:32,480
But, when the brief summer comes, temperatures rise and winds slacken.

176
00:27:48,000 --> 00:27:51,000
It's now that visitors arrive.

177
00:27:53,840 --> 00:27:57,480
All here to breed before winter returns.

178
00:27:59,840 --> 00:28:01,560
There's the Snares penguins.

179
00:28:10,200 --> 00:28:12,040
Shearwaters come, too.

180
00:28:14,920 --> 00:28:18,760
This is an excellent place for them to dig their nesting burrows,

181
00:28:18,760 --> 00:28:21,240
for no predators have managed to get here.

182
00:28:27,400 --> 00:28:30,840
Soon the island is crowded with birds.

183
00:28:32,400 --> 00:28:36,280
Every one of them eager to make the most of the short breeding season.

184
00:28:40,440 --> 00:28:43,080
But not everyone has a partner.

185
00:28:49,560 --> 00:28:52,960
A male Buller's albatross waits for his mate.

186
00:28:56,120 --> 00:29:00,280
Each year they spend six months apart, travelling the ocean.

187
00:29:05,720 --> 00:29:08,280
They reunite here to breed.

188
00:29:11,280 --> 00:29:13,320
But this year, she's late.

189
00:29:17,360 --> 00:29:19,320
No, that's not her.

190
00:29:23,640 --> 00:29:25,800
The other birds come and go.

191
00:29:36,040 --> 00:29:37,440
The clock is ticking.

192
00:29:38,760 --> 00:29:40,640
If she doesn't appear soon,

193
00:29:40,640 --> 00:29:43,480
it could be too late for them to breed successfully.

194
00:29:46,320 --> 00:29:50,560
Every morning the shearwaters fly off to collect food for their young.

195
00:30:08,480 --> 00:30:11,440
Everybody else seems to be getting on with it.

196
00:30:24,200 --> 00:30:28,200
The shearwaters' return marks another lost day.

197
00:30:30,560 --> 00:30:35,880
There are three million birds on the island, but only one matters to him.

198
00:30:43,120 --> 00:30:44,800
Could this be her?

199
00:30:51,440 --> 00:30:52,560
At last.

200
00:31:07,000 --> 00:31:09,320
At first, he's a little coy.

201
00:31:23,520 --> 00:31:24,920
But not for long.

202
00:31:32,360 --> 00:31:35,280
They greet each other with the special dance

203
00:31:35,280 --> 00:31:37,920
they've perfected over many years.

204
00:31:48,720 --> 00:31:54,240
There is much to do if they're to raise a chick before winter returns.

205
00:31:58,840 --> 00:32:03,840
But when you have been apart for six months, some things can't be rushed.

206
00:32:22,680 --> 00:32:28,600
Islands in warm tropical waters don't experience seasonal extremes.

207
00:32:31,800 --> 00:32:35,040
The Seychelles, lying off the coast of East Africa,

208
00:32:35,040 --> 00:32:37,920
provide a sanctuary for sea birds all the year round.

209
00:32:54,680 --> 00:32:57,640
Fairy terns are permanent residents.

210
00:32:59,120 --> 00:33:03,840
They take a fairly relaxed view about what constitutes a nest.

211
00:33:05,360 --> 00:33:07,520
A bare branch is quite enough.

212
00:33:16,240 --> 00:33:20,400
Climbing onto it to incubate has to be done with care.

213
00:33:29,560 --> 00:33:32,000
Once a year, the noddies arrive.

214
00:33:33,760 --> 00:33:35,360
They do make nests,

215
00:33:35,360 --> 00:33:38,000
and pisonia trees provide their young

216
00:33:38,000 --> 00:33:41,240
with a rather less precarious start in life.

217
00:33:47,920 --> 00:33:50,200
Nesting on this island looks idyllic.

218
00:33:51,840 --> 00:33:55,760
But behind the beauty, there's a sinister side.

219
00:34:00,320 --> 00:34:05,200
The Seychelles fody makes quick work of an unattended egg.

220
00:34:20,480 --> 00:34:23,280
She knows something's not quite right,

221
00:34:23,280 --> 00:34:25,600
but her drive to incubate is strong.

222
00:34:40,400 --> 00:34:42,400
The noddies too have a problem.

223
00:34:46,520 --> 00:34:48,320
As their chicks grow,

224
00:34:48,320 --> 00:34:52,440
so the pisonia trees develop seeds that are sticky

225
00:34:52,440 --> 00:34:54,440
and equipped with hooks.

226
00:34:59,520 --> 00:35:01,760
By the time the young noddies leave,

227
00:35:01,760 --> 00:35:05,960
they carry these hitchhiking seeds away to other islands.

228
00:35:12,440 --> 00:35:16,520
But sometimes the pisonia trees are too successful.

229
00:35:22,240 --> 00:35:26,520
If a fledgling, testing out its wings, drops to the ground,

230
00:35:26,520 --> 00:35:28,800
it can get covered with the seeds.

231
00:35:37,200 --> 00:35:42,200
Entangled and weighed down, if it can't free itself,

232
00:35:42,200 --> 00:35:43,640
the youngster will starve.

233
00:35:57,120 --> 00:36:01,000
The pisonia may have failed to disperse these seeds...

234
00:36:02,600 --> 00:36:06,280
..but it will soon have fertiliser for its roots.

235
00:36:12,640 --> 00:36:18,280
This is why some people call the pisonia the "bird catcher tree".

236
00:36:51,640 --> 00:36:54,640
The fairy tern laid another egg,

237
00:36:54,640 --> 00:36:57,640
and now she has a tiny chick to feed.

238
00:37:04,160 --> 00:37:05,640
This chick is lucky.

239
00:37:08,400 --> 00:37:12,440
By the time it fledges, the pisonia seeds will have dispersed,

240
00:37:12,440 --> 00:37:14,840
and the danger they brought will be gone.

241
00:37:26,080 --> 00:37:30,280
Even the most idyllic-looking of islands presents challenges

242
00:37:30,280 --> 00:37:31,960
for the animals living there.

243
00:37:33,000 --> 00:37:37,440
But the greatest threat they face is change.

244
00:37:53,360 --> 00:37:55,960
Christmas Island in the Indian Ocean.

245
00:37:57,520 --> 00:37:59,320
For millions of years,

246
00:37:59,320 --> 00:38:03,240
this remote speck of land has been ruled by crabs.

247
00:38:09,600 --> 00:38:12,320
Their ancestors came from the sea,

248
00:38:12,320 --> 00:38:16,600
but most have now adopted a land-based existence.

249
00:38:25,600 --> 00:38:30,000
Given there are so many of them, they get on relatively harmoniously.

250
00:38:32,520 --> 00:38:38,240
They're the gardeners and caretakers of a tiny crab utopia.

251
00:38:42,040 --> 00:38:45,040
Once a year, they must all return to the sea to breed,

252
00:38:45,040 --> 00:38:47,720
and the march of the red crabs

253
00:38:47,720 --> 00:38:51,800
is one of the greatest natural spectacles on earth.

254
00:39:03,480 --> 00:39:05,960
There are 50 million of them.

255
00:39:12,600 --> 00:39:16,920
It's an event that has brought the island worldwide fame.

256
00:39:27,920 --> 00:39:29,480
But in recent years,

257
00:39:29,480 --> 00:39:33,240
millions of red crabs haven't managed to reach the sea.

258
00:39:39,440 --> 00:39:42,360
An invader has occupied this island.

259
00:39:45,440 --> 00:39:47,480
Yellow crazy ants.

260
00:39:48,560 --> 00:39:52,880
They escaped from visiting ships and with no predators to control them,

261
00:39:52,880 --> 00:39:57,000
they have now created vast super colonies in the forest.

262
00:40:02,960 --> 00:40:07,560
When migrating red crabs march into their territory, the ants attack.

263
00:40:09,280 --> 00:40:12,680
Squirting acid into the crabs' eyes and mouths.

264
00:40:22,880 --> 00:40:25,040
The crabs have no defence.

265
00:40:28,680 --> 00:40:30,520
Blinded and confused...

266
00:40:31,760 --> 00:40:32,960
..they're doomed.

267
00:40:44,440 --> 00:40:47,920
Humans brought these ant invaders here,

268
00:40:47,920 --> 00:40:50,400
and now humans are having to control them.

269
00:40:54,240 --> 00:40:59,680
Isolated communities may evolve from millions of years in relative peace.

270
00:41:01,200 --> 00:41:05,240
But, when new challenges arrive, they can struggle to cope.

271
00:41:08,080 --> 00:41:12,640
Of all the species that have become extinct in recent years,

272
00:41:12,640 --> 00:41:15,560
around 80% have been islanders.

273
00:41:18,160 --> 00:41:23,920
Our impact on the Earth is greater today than ever before.

274
00:41:25,480 --> 00:41:27,560
Yet some islands are so remote

275
00:41:27,560 --> 00:41:30,480
that few humans have even set foot on them.

276
00:41:34,280 --> 00:41:36,240
Zavodovski Island is one.

277
00:41:40,560 --> 00:41:43,400
It lies in the great Southern Ocean.

278
00:41:43,400 --> 00:41:46,680
It's not only surrounded by the stormiest of seas,

279
00:41:46,680 --> 00:41:49,240
it is itself an active volcano.

280
00:41:52,160 --> 00:41:55,240
It's the last place on Earth you would choose to live.

281
00:42:04,360 --> 00:42:07,280
Unless you're a chinstrap penguin.

282
00:42:10,080 --> 00:42:13,480
There is plenty of food in these waters, but to exploit it,

283
00:42:13,480 --> 00:42:15,640
the penguins have to risk their lives.

284
00:43:04,800 --> 00:43:08,360
Life here is dangerous in the extreme.

285
00:43:22,160 --> 00:43:24,360
PENGUINS CHATTER

286
00:43:25,640 --> 00:43:29,120
But there are some benefits from living on a volcano.

287
00:43:31,680 --> 00:43:35,880
Its warmth melts the snow early in the year.

288
00:43:35,880 --> 00:43:39,320
And, by January, the Antarctic's mid-summer,

289
00:43:39,320 --> 00:43:41,680
the island is covered in chicks.

290
00:43:46,160 --> 00:43:48,640
Parents take turns at guarding them

291
00:43:48,640 --> 00:43:51,960
until they're large enough to be left alone.

292
00:43:56,400 --> 00:44:01,400
This mother's chicks are hungry, but she has no food left to give them.

293
00:44:03,160 --> 00:44:07,240
Their survival depends on their father returning with the next meal.

294
00:44:11,720 --> 00:44:13,360
But some don't make it.

295
00:44:27,520 --> 00:44:31,760
Skuas harass the colony, hoping to snatch a chick.

296
00:44:39,320 --> 00:44:41,120
She can't risk leaving them.

297
00:44:46,200 --> 00:44:50,040
Everything will be fine, as long as their father comes back soon.

298
00:45:19,360 --> 00:45:24,360
He's been fishing 50 miles offshore, but now he's not far away.

299
00:45:27,360 --> 00:45:30,760
For him, however, and for all the other parents here,

300
00:45:30,760 --> 00:45:33,080
the worst of the journey is still to come.

301
00:46:05,280 --> 00:46:09,640
Tiny claws help him to get whatever grip he can on the rough lava.

302
00:46:37,520 --> 00:46:40,400
For these commuters, it's rush hour.

303
00:46:42,040 --> 00:46:44,760
Some have had a really bad day.

304
00:46:49,080 --> 00:46:53,360
The father now has a two-mile walk to the nest,

305
00:46:53,360 --> 00:46:55,800
and a stomach loaded with food doesn't help.

306
00:47:02,880 --> 00:47:06,520
This is the largest penguin colony in the world.

307
00:47:13,560 --> 00:47:16,920
But as he makes the same journey every other day,

308
00:47:16,920 --> 00:47:19,960
he should be able to do it with his eyes closed.

309
00:47:28,560 --> 00:47:31,720
It's true that there can be safety in numbers,

310
00:47:31,720 --> 00:47:34,200
but numbers can also be something of a problem

311
00:47:34,200 --> 00:47:36,600
when you're trying to find your own nest.

312
00:47:43,120 --> 00:47:45,000
The mother is still waiting.

313
00:47:47,200 --> 00:47:49,080
Her chicks are now desperate.

314
00:47:49,080 --> 00:47:50,880
THEY CHEEP

315
00:47:55,040 --> 00:47:57,760
In the midst of all this deafening chorus,

316
00:47:57,760 --> 00:47:59,800
he can recognise her particular cry.

317
00:48:19,640 --> 00:48:21,000
At last.

318
00:48:36,120 --> 00:48:38,480
Both chicks will get a meal.

319
00:48:45,360 --> 00:48:50,160
With a head bob of acknowledgement, their mother now leaves.

320
00:48:50,160 --> 00:48:53,360
It's her turn to do the feeding run.

321
00:48:59,720 --> 00:49:06,400
This formidable commute is the price these penguins pay for sanctuary.

322
00:49:12,240 --> 00:49:15,760
A strange vision of paradise to us, perhaps,

323
00:49:15,760 --> 00:49:21,560
but, for one and a half million penguins, this island has it all.

324
00:49:32,160 --> 00:49:36,080
Islands may seem remote and insignificant,

325
00:49:36,080 --> 00:49:40,880
but they are home to some of the most precious wildlife on Earth.

326
00:50:03,640 --> 00:50:06,720
The expedition to film on the island of Zavodovski

327
00:50:06,720 --> 00:50:09,320
was the most intrepid shoot of the series.

328
00:50:10,320 --> 00:50:13,600
To ensure its success, the team have called in

329
00:50:13,600 --> 00:50:16,080
Antarctic expert Jerome Poncet,

330
00:50:16,080 --> 00:50:19,240
one of the few people to have set foot on the island.

331
00:50:21,560 --> 00:50:25,320
This whole region of Antarctica is rarely visited.

332
00:50:29,320 --> 00:50:32,400
And this is the planet's roughest ocean.

333
00:50:41,120 --> 00:50:43,680
After seven long days and nights at sea,

334
00:50:43,680 --> 00:50:46,600
they get their first glimpse of the final destination.

335
00:50:46,600 --> 00:50:49,600
It's actually quite surreal after a whole year,

336
00:50:49,600 --> 00:50:51,480
trying to put the expedition together.

337
00:50:51,480 --> 00:50:53,840
And then today we wake up, and there's the volcano.

338
00:50:53,840 --> 00:50:55,320
That's Zavodovski.

339
00:50:56,520 --> 00:50:59,400
The explorers who discovered this place

340
00:50:59,400 --> 00:51:02,600
spoke of the stench of sulphurous gases,

341
00:51:02,600 --> 00:51:05,320
treacherous waters,

342
00:51:05,320 --> 00:51:07,920
and astonishing numbers of penguins.

343
00:51:11,600 --> 00:51:13,800
It seems not much has changed.

344
00:51:15,400 --> 00:51:17,600
Jerome's been round the whole place,

345
00:51:17,600 --> 00:51:20,560
and there literally is only one safe area to get on,

346
00:51:20,560 --> 00:51:21,720
and he's telling us

347
00:51:21,720 --> 00:51:23,400
it's that rock face over there.

348
00:51:26,000 --> 00:51:29,040
The team must take everything they need to survive.

349
00:51:30,400 --> 00:51:31,800
There are the penguins!

350
00:51:34,000 --> 00:51:35,600
Though the boat'll stay nearby,

351
00:51:35,600 --> 00:51:37,520
they will need to be self-sufficient.

352
00:51:38,880 --> 00:51:42,560
But that means taking a tonne of equipment up this cliff.

353
00:51:42,560 --> 00:51:45,200
Just get to that lot to help.

354
00:51:45,200 --> 00:51:46,800
Many flippers make light work.

355
00:51:49,600 --> 00:51:51,920
They work all day getting the gear ashore.

356
00:51:54,920 --> 00:51:58,080
But the fact there are so many penguins on the island

357
00:51:58,080 --> 00:51:59,680
doesn't make it easy.

358
00:52:00,880 --> 00:52:03,600
The hardest thing for us has been finding a pathway through,

359
00:52:03,600 --> 00:52:06,920
because there's absolutely penguins everywhere you look.

360
00:52:13,840 --> 00:52:16,000
Finally, it's time to make camp.

361
00:52:21,120 --> 00:52:24,760
They choose a sheltered place that won't disturb the locals.

362
00:52:26,320 --> 00:52:30,120
But since most of the penguins won't have seen a human being before,

363
00:52:30,120 --> 00:52:32,520
they seem keen to pop over and visit.

364
00:52:33,720 --> 00:52:36,240
- Hello. 
- Nosy neighbours.

365
00:52:38,000 --> 00:52:39,480
The team set off

366
00:52:39,480 --> 00:52:42,640
to start documenting the daily lives of the penguins,

367
00:52:42,640 --> 00:52:45,120
and what they find is astonishing.

368
00:52:46,120 --> 00:52:49,680
As soon as you walk over that ridge, you sort of get a tingly feeling,

369
00:52:49,680 --> 00:52:54,000
because I've never seen that many animals in one spot.

370
00:52:54,000 --> 00:52:55,520
It's mind-blowing.

371
00:52:57,800 --> 00:53:00,160
It's like Glastonbury Festival.

372
00:53:00,160 --> 00:53:01,400
The whole landscape

373
00:53:01,400 --> 00:53:05,480
is full of little black and white penguins waddling around.

374
00:53:09,760 --> 00:53:12,800
This is penguin paradise, and that's what we're trying to show.

375
00:53:17,720 --> 00:53:18,960
A promising start.

376
00:53:20,560 --> 00:53:23,560
But here, fortunes can change quickly.

377
00:53:27,560 --> 00:53:29,160
# Summertime... #

378
00:53:32,800 --> 00:53:35,040
Every season within ten minutes.

379
00:53:38,800 --> 00:53:42,880
As the snow melts, it creates an unforeseen problem.

380
00:53:44,920 --> 00:53:46,520
We purposely chose this campsite

381
00:53:46,520 --> 00:53:49,640
because it was a place where the penguins didn't seem to go.

382
00:53:49,640 --> 00:53:52,880
I think we've realised why the penguins don't nest here.

383
00:53:52,880 --> 00:53:55,760
It's because of the spray and because of some run-off,

384
00:53:55,760 --> 00:53:58,280
so we are literally in a bit of a bog.

385
00:53:59,440 --> 00:54:01,400
And it's not just mud.

386
00:54:03,320 --> 00:54:07,560
A couple of these guys, as they wander down to do a spot of fishing,

387
00:54:07,560 --> 00:54:11,960
they tend to use my tent as a little poop spot.

388
00:54:11,960 --> 00:54:13,760
You kind of get used to it at night,

389
00:54:13,760 --> 00:54:16,960
just hearing a constant splat on top of the tent.

390
00:54:16,960 --> 00:54:20,160
But, as you can see, all of the kit,

391
00:54:20,160 --> 00:54:23,760
I'm afraid that's getting splat on as well.

392
00:54:23,760 --> 00:54:27,360
And, when the wind changes, it brings a noxious reminder

393
00:54:27,360 --> 00:54:30,200
that they're camping on an active volcano.

394
00:54:32,560 --> 00:54:35,120
It's the first time we've smelt sulphur,

395
00:54:35,120 --> 00:54:38,360
which is welcome relief from smelling penguins.

396
00:54:38,360 --> 00:54:39,760
It's smoking away.

397
00:54:41,360 --> 00:54:44,400
I think if they start running for the sea,

398
00:54:44,400 --> 00:54:47,360
we're going to be calling Jerome pretty quick for the boat.

399
00:54:49,880 --> 00:54:54,040
Each day filming on Zavodovski seems to present a new challenge.

400
00:54:58,320 --> 00:55:01,280
Next, a huge storm hits the island.

401
00:55:04,320 --> 00:55:06,280
Only now do the team realise

402
00:55:06,280 --> 00:55:09,400
just how tough life can be for the penguins.

403
00:55:13,080 --> 00:55:16,440
It's hard not to be moved by the effort they go to

404
00:55:16,440 --> 00:55:18,040
to feed their chicks.

405
00:55:20,000 --> 00:55:22,480
These huge waves are coming in.

406
00:55:22,480 --> 00:55:24,480
The penguins are surfing here,

407
00:55:24,480 --> 00:55:26,640
getting battered on these big boulders.

408
00:55:26,640 --> 00:55:29,400
Now and then you just get a penguin that gets catapulted

409
00:55:29,400 --> 00:55:32,520
15 metres in the air - it's totally ludicrous.

410
00:55:34,880 --> 00:55:38,920
And really, I think there are quite a few penguins getting killed in it.

411
00:55:43,960 --> 00:55:48,080
The beach in the afternoon was just a scene of death and destruction.

412
00:55:50,000 --> 00:55:51,680
It was absolute carnage.

413
00:55:54,000 --> 00:55:55,160
It was heartbreaking.

414
00:55:55,160 --> 00:55:58,040
I mean, they're trying so hard to get up the beach with broken legs

415
00:55:58,040 --> 00:56:02,960
and bleeding and very, you know, sobering, really.

416
00:56:06,520 --> 00:56:10,160
After witnessing the struggles, the penguins must endure,

417
00:56:10,160 --> 00:56:12,320
the team now face the same problem.

418
00:56:13,600 --> 00:56:14,840
Getting off the island.

419
00:56:16,320 --> 00:56:20,440
With another storm coming in, they decide to take their chance.

420
00:56:22,480 --> 00:56:26,240
Jerome has seconds to get in and out between the waves.

421
00:56:27,360 --> 00:56:28,720
Or the Zodiac could tip...

422
00:56:30,080 --> 00:56:31,680
..leaving them all stranded.

423
00:56:32,880 --> 00:56:35,640
Hurray, that's the first box off the island.

424
00:56:40,800 --> 00:56:44,600
What took a day to get ashore must be off in minutes.

425
00:56:44,600 --> 00:56:46,200
And the swell is getting bigger.

426
00:56:48,280 --> 00:56:50,800
Their window of opportunity is closing.

427
00:56:52,480 --> 00:56:54,440
Look at this swell now, watch out, watch out!

428
00:57:00,920 --> 00:57:04,240
The equipment's off, but now the team has to follow.

429
00:57:09,160 --> 00:57:11,480
She's just leaving us now, is she?

430
00:57:11,480 --> 00:57:14,080
That's the producer, she's gone! We have to swim now.

431
00:57:16,640 --> 00:57:17,960
- They're gone. 
- Yeah.

432
00:57:19,120 --> 00:57:21,320
Luckily it didn't come to that.

433
00:57:25,960 --> 00:57:31,320
Safely aboard, they leave with an unforgettable experience

434
00:57:31,320 --> 00:57:35,640
of how hard life is on an island at the edge of the world.

435
00:57:40,200 --> 00:57:45,520
Next time, we ascend into the planet's highest peaks

436
00:57:45,520 --> 00:57:48,360
to discover a spectacular but hostile world,

437
00:57:48,360 --> 00:57:51,160
where only the toughest animals can endure.

438
00:57:54,000 --> 00:57:57,040
This is life on the roof of the world.

439
00:57:57,040 --> 00:57:58,360
Mountains.
