Earth is the only planet we
know of where life exists.

4
00:00:41,295 --> 00:00:44,135
And, here, it does so in abundance.

5
00:00:49,095 --> 00:00:51,415
The jungle is Eden.

6
00:00:54,375 --> 00:00:57,974
It covers less than 6%
of the Earth's surface

7
00:00:57,975 --> 00:01:00,134
but it's home to half of all

8
00:01:00,135 --> 00:01:01,975
the plants and animals on land.

9
00:01:06,495 --> 00:01:09,134
Jungles have just the
right amount of light,

10
00:01:09,135 --> 00:01:14,535
water and nutrients, and they
have had every day for millennia.

11
00:01:19,175 --> 00:01:21,975
Life here should be easy.

12
00:01:30,655 --> 00:01:32,375
This is an indri.

13
00:01:35,455 --> 00:01:37,215
It's a primate, like us.

14
00:01:38,335 --> 00:01:42,535
And these forests in
Madagascar are its home.

15
00:01:49,735 --> 00:01:51,295
But to survive here...

16
00:01:52,455 --> 00:01:55,295
...it has to face one major challenge.

17
00:02:01,495 --> 00:02:03,615
Paradise is crowded.

18
00:02:07,615 --> 00:02:09,895
Life fills every niche.

19
00:02:12,175 --> 00:02:17,534
And, at any one time, a staggering
variety of species and countless

20
00:02:17,535 --> 00:02:22,095
individuals are striving
for space and food.

21
00:02:31,455 --> 00:02:33,534
Like every jungle animal,

22
00:02:33,535 --> 00:02:37,094
indri have to find their own way to survive

23
00:02:37,095 --> 00:02:40,215
in the most competitive place on Earth.

(INDRI WAILS)

26
00:03:05,375 --> 00:03:07,815
Jungles are complex places...

27
00:03:09,415 --> 00:03:14,815
...tangled three-dimensional worlds
created by lush tropical vegetation.

28
00:03:18,815 --> 00:03:24,095
90% of the animals here spend
their whole lives up in the trees.

29
00:03:25,175 --> 00:03:28,855
And each of them has to find
its own way of getting around.

30
00:03:32,215 --> 00:03:36,415
Hanging 100 feet above the
ground, a spider monkey.

31
00:03:42,735 --> 00:03:46,814
They travel in family groups and
find everything they need in the top

32
00:03:46,815 --> 00:03:48,455
storey of the jungle.

33
00:03:50,015 --> 00:03:53,055
Up here isn't a place
for the faint-hearted.

34
00:03:56,495 --> 00:04:00,614
With long limbs and a prehensile
tail that can grip like a hand,

35
00:04:00,615 --> 00:04:02,135
they're built for climbing.

36
00:04:08,895 --> 00:04:13,775
But imagine having to learn
these skills as high up as this.

37
00:04:19,095 --> 00:04:22,975
One third of spider monkeys
never make it to adulthood.

38
00:04:26,455 --> 00:04:29,215
This youngster is only a few months old.

39
00:04:31,575 --> 00:04:34,855
Her future depends on her ability to climb.

40
00:04:37,735 --> 00:04:41,134
Playing on a practice tree with
her older brother and sister,

41
00:04:41,135 --> 00:04:44,695
she's already learning to use
her tail as a safety line...

42
00:04:48,535 --> 00:04:51,095
...under her father's close watch.

(THEY CHATTER)

44
00:05:05,415 --> 00:05:09,454
She's keen to join in the game
but she's the youngest and,

45
00:05:09,455 --> 00:05:12,615
as is the way of things,
she's not always welcome.

46
00:05:16,375 --> 00:05:17,415
(SHE GIBBERS)

47
00:05:18,775 --> 00:05:21,735
So she chooses her own place to play.

48
00:05:27,855 --> 00:05:30,334
But not all trees are the same.

49
00:05:30,335 --> 00:05:34,095
This one is for more advanced climbers.

50
00:05:43,895 --> 00:05:46,215
Enthusiasm? Certainly!

52
00:05:52,535 --> 00:05:53,575

(SHE CHATTERS)

54
00:05:57,175 --> 00:05:58,495
Room for improvement.

55
00:06:01,855 --> 00:06:05,934
Meanwhile, some of her family have
moved on to look for a new patch of

56
00:06:05,935 --> 00:06:06,975
fresh food.

57
00:06:09,815 --> 00:06:12,695
The top of the canopy isn't for youngsters.

58
00:06:14,055 --> 00:06:19,214
But Father's not looking and the
temptation to join the others is

59
00:06:19,215 --> 00:06:20,255
irresistible.

60
00:06:27,815 --> 00:06:30,014
She'll need to be careful.

61
00:06:30,015 --> 00:06:32,935
A fall from here would mean certain death.

62
00:06:40,975 --> 00:06:44,895
It's the first time she's been
as high as this on her own.

63
00:06:56,335 --> 00:07:00,335
As she climbs still higher, the
branches get thinner and thinner.

(SHE SCREECHES)

66
00:07:25,215 --> 00:07:26,775
Her tail has caught her...

67
00:07:27,775 --> 00:07:32,175
...but now she's stuck in mid-air,
unable to reach any other branch.

68
00:07:34,295 --> 00:07:35,695
(SHE SCREECHES)

69
00:07:45,375 --> 00:07:47,735
Father, however, was watching.

70
00:07:50,015 --> 00:07:54,014
He's big and strong enough to form a
bridge with his body so that she can

71
00:07:54,015 --> 00:07:55,055
climb to safety.

72
00:08:26,055 --> 00:08:27,295
Lesson learned.

73
00:08:33,415 --> 00:08:37,455
But it's not just monkeys that
live here, up in the treetops.

74
00:08:44,855 --> 00:08:50,535
And, if you are small, finding the
right tree can mean a home for life.

75
00:08:56,455 --> 00:08:58,534
He's a Draco lizard.

76
00:08:58,535 --> 00:09:02,295
He's only the size of a
pencil and he eats ants.

77
00:09:09,855 --> 00:09:14,734
This one tree could provide him
with all he will ever need...

78
00:09:14,735 --> 00:09:16,575
a conveyor belt of food.

79
00:09:20,135 --> 00:09:22,575
It's a perfect place to settle down.

80
00:09:29,415 --> 00:09:31,015
Well, it would be...

81
00:09:33,495 --> 00:09:35,095
...but there's already someone here.

82
00:09:44,655 --> 00:09:48,334
This larger male is the tree's owner.

83
00:09:48,335 --> 00:09:50,495
And Dracos don't share.

84
00:09:58,695 --> 00:10:01,815
The owner's flag is a warning.

85
00:10:05,295 --> 00:10:07,815
Trespassers won't be tolerated.

86
00:10:10,375 --> 00:10:12,175
The owner's not only intimidating...

87
00:10:14,855 --> 00:10:16,575
...he's prepared to battle.

88
00:10:29,535 --> 00:10:30,575
A dead end.

89
00:10:32,695 --> 00:10:34,735
Safety is a long way away.

90
00:10:37,615 --> 00:10:39,135
Now he must choose.

91
00:10:41,015 --> 00:10:42,055
Fight...

92
00:10:45,655 --> 00:10:47,095
...or flee?

93
00:11:03,975 --> 00:11:08,815
Only in the jungle do you find
lizards that can soar like dragons.

94
00:11:12,615 --> 00:11:16,375
He can travel over 100
feet in a single leap.

95
00:11:18,535 --> 00:11:22,295
It's a very fast and efficient
way to move through the jungle.

96
00:11:29,975 --> 00:11:34,855
Maybe this new tree will have
food and no resident owner.

97
00:11:43,215 --> 00:11:46,855
Everything in the jungle
has to compete for space.

98
00:11:52,095 --> 00:11:55,175
Only 2% of the sun's
rays reach the ground...

99
00:11:56,135 --> 00:11:58,574
...so even the plants
must battle for the light

100
00:11:58,575 --> 00:12:00,135
they need if they're to grow.

101
00:12:07,535 --> 00:12:12,095
300 years ago, this Hura
tree began its race for light.

102
00:12:14,055 --> 00:12:19,414
And every day since, it has absorbed
the water and sunshine it needed to

103
00:12:19,415 --> 00:12:21,495
grow into a giant.

104
00:12:30,535 --> 00:12:34,935
It has succeeded in doing what
every tree must do to survive...

105
00:12:36,575 --> 00:12:39,055
...rise above the gloom
of the jungle floor.

106
00:12:47,335 --> 00:12:51,455
And, what is more, its success
has given life to others.

107
00:13:01,735 --> 00:13:05,615
Its branches now carry 1,000 other plants.

108
00:13:09,455 --> 00:13:11,174
These particular ferns,

109
00:13:11,175 --> 00:13:15,495
figs and orchids live only on
the branches of other trees.

110
00:13:20,575 --> 00:13:24,535
1,000 plants growing on one single tree.

111
00:13:26,735 --> 00:13:30,975
Throughout the forest, this
story is repeated endless times.

112
00:13:35,375 --> 00:13:37,854
As a consequence, jungles are home

113
00:13:37,855 --> 00:13:41,775
to more species of plants
than anywhere else on Earth.

114
00:13:42,815 --> 00:13:47,015
And they, in turn, support
a wealth of animals.

115
00:13:52,535 --> 00:13:56,855
In Ecuador, the competition
is at its most intense.

116
00:13:58,855 --> 00:14:02,215
Here, there are 100 species
of hummingbirds alone...

117
00:14:05,295 --> 00:14:07,135
...all fighting for nectar.

118
00:14:09,895 --> 00:14:13,454
Each flower only has a
small amount at any one time,

119
00:14:13,455 --> 00:14:15,695
and so it's first come, first served.

120
00:14:20,495 --> 00:14:25,334
One hummingbird has gone to
great lengths to avoid conflict

121
00:14:25,335 --> 00:14:26,855
with other species.

122
00:14:30,975 --> 00:14:35,735
Swordbills are the only bird with
a beak longer than their body.

123
00:14:38,655 --> 00:14:42,774
And some flowers are too elongated
for the other 99 species of

124
00:14:42,775 --> 00:14:45,095
hummingbirds here to feed from them.

125
00:14:57,655 --> 00:15:00,414
A swordbill's extraordinary beak, however,

126
00:15:00,415 --> 00:15:03,455
enables it to reach the
places that others can't...

127
00:15:07,535 --> 00:15:11,655
...the top of this flower, where
the sweet nectar is produced.

128
00:15:13,415 --> 00:15:17,975
It has found a solution that means
it doesn't have to join the fight.

129
00:15:20,935 --> 00:15:24,974
And, as each long flower blooms, it
gives the swordbill a fresh supply

130
00:15:24,975 --> 00:15:27,095
of food all to itself.

131
00:15:42,895 --> 00:15:46,855
But having a beak longer than
your body does have its drawbacks.

132
00:15:51,735 --> 00:15:54,375
For a start, it's tricky to keep it clean.

133
00:16:06,855 --> 00:16:10,495
Harder still, how do you
preen your body feathers?

134
00:16:13,455 --> 00:16:14,974
Unlike the other hummers,

135
00:16:14,975 --> 00:16:18,215
swordbills can't reach their
feathers with their beak.

136
00:16:25,735 --> 00:16:28,935
The only option, a good old scratch.

137
00:16:47,735 --> 00:16:49,735
It's a little unrefined...

138
00:16:52,215 --> 00:16:56,455
...but a small price to pay
for an exclusive food supply...

139
00:17:00,055 --> 00:17:04,814
...especially when feeding times
are only too frequently interrupted

140
00:17:04,815 --> 00:17:06,854
by storms.

(THUNDER RUMBLES)

142
00:17:14,295 --> 00:17:16,974
Jungles are the richest places on Earth

143
00:17:16,975 --> 00:17:19,335
because of one remarkable fact...

144
00:17:22,615 --> 00:17:24,455
...they make their own weather.

145
00:17:30,335 --> 00:17:34,735
Every day, water rises from the
surface of the leaves as vapour.

146
00:17:37,095 --> 00:17:40,255
It's as if the trees breathe out clouds.

147
00:17:43,215 --> 00:17:46,335
They gather over the
forest until, finally...

148
00:17:49,255 --> 00:17:50,295
...they burst.

149
00:18:05,175 --> 00:18:08,855
Rain is the lifeblood of every jungle.

150
00:18:18,335 --> 00:18:22,335
And all have to do their best
to endure the daily downpour.

151
00:19:05,135 --> 00:19:08,414
In some jungles, like here in Brazil,

152
00:19:08,415 --> 00:19:12,774
it rains so much that, for
part of the year, the trees are

153
00:19:12,775 --> 00:19:14,455
almost totally submerged.

154
00:19:23,335 --> 00:19:27,175
The forest floor is 30 feet
below the water's surface.

155

This is a mysterious world, a
place few people have ever explored.

156

animals for which this is home...

...including some you might never
expect to find amongst trees.

158

Here, 1,000 miles from
the sea, are dolphins.

In these black, tangled waters, they
have become almost totally blind,

00:20:46,775 --> 00:20:48,854
so they move slowly,

163
00:20:48,855 --> 00:20:53,535
carefully using their sonar to
scan the forest floor for fish.

164
00:20:59,175 --> 00:21:02,495
If this forest can hide
a new species of dolphin...

165

...what else might there
be here, awaiting discovery?

of the flooded jungle,

00:21:47,655 --> 00:21:49,014
(SPLASH)

175
00:21:49,015 --> 00:21:50,055
...caiman.

176
00:21:51,815 --> 00:21:54,734
They grow to ten feet
long and kill anything

177
00:21:54,735 --> 00:21:56,735
they get between their jaws.

178
00:22:02,575 --> 00:22:05,215
But there are more artful hunters...

179
00:22:07,135 --> 00:22:09,695
...drawn here from the surrounding forest.

180
00:22:21,975 --> 00:22:25,735
A jaguar, the supreme jungle predator.

181
00:22:33,135 --> 00:22:35,895
The river marks the
edge of his territory...

182
00:22:37,975 --> 00:22:40,535
...but here he has competition.

183
00:22:43,055 --> 00:22:44,855
(THEY GROWL)

184
00:22:45,975 --> 00:22:48,775
(THEY ROAR)

185
00:22:57,255 --> 00:23:00,135
(THEY GROWL)

186
00:23:02,895 --> 00:23:05,455
He's now in the territory of a female.

187
00:23:11,175 --> 00:23:15,015
She has ruled this stretch
of river for five years.

188
00:23:17,455 --> 00:23:19,935
This is her place to hunt.

189
00:23:49,495 --> 00:23:52,455
Capybara are strong and wary.

190
00:23:55,815 --> 00:23:57,695
The key is stealth.

191
00:24:16,055 --> 00:24:20,535
She needs to get within
three feet if she's to pounce.

192
00:24:43,335 --> 00:24:44,495
Not this time.

193
00:24:55,455 --> 00:24:57,415
She's not the only female here.

194
00:24:59,375 --> 00:25:03,575
Each part of this jungle's edge
is ruled by a different queen.

195
00:25:14,575 --> 00:25:19,535
Few places on Earth have enough
food to support so many big cats.

196
00:25:24,415 --> 00:25:26,655
(LOW GROWL)

197
00:25:45,575 --> 00:25:47,935
The male hunts in a different way.

198
00:25:55,535 --> 00:25:59,615
Weighing almost 300 lbs,
it's hard to be stealthy...

199
00:26:02,695 --> 00:26:05,814
...and with so many other jaguars around,

200
00:26:05,815 --> 00:26:08,575
he doesn't bother with wary capybara.

201
00:26:14,935 --> 00:26:17,135
He seeks a different prey.

202
00:26:40,375 --> 00:26:43,294
He's become a killer

203
00:26:43,295 --> 00:26:44,735
of killers.

204
00:27:10,495 --> 00:27:15,255
Jaguars have the most
powerful bite of any cat.

205
00:27:18,735 --> 00:27:22,175
And he knows the caiman's
most vulnerable point...

206
00:27:24,055 --> 00:27:25,935
...the back of its skull.

207
00:27:27,575 --> 00:27:29,695
(CRUNCHING)

208
00:27:53,655 --> 00:27:57,694
Hunters living in the dense
understorey of the jungle

209
00:27:57,695 --> 00:28:00,175
come in all shapes and sizes.

210
00:28:02,535 --> 00:28:04,695
But they share a problem.

211
00:28:10,895 --> 00:28:14,695
How to tell what is a
plant, and what is prey.

212
00:28:18,055 --> 00:28:22,334
This is a game of hide and
seek that can be won or lost

213
00:28:22,335 --> 00:28:24,055
in the blink of an eye.

214
00:28:54,255 --> 00:28:57,894
The long contest between predator and prey

215
00:28:57,895 --> 00:29:01,535
has produced mimicry
of astounding accuracy.

216
00:29:19,055 --> 00:29:23,495
A leaf-tailed gecko
masquerading as lichen.

217
00:29:48,735 --> 00:29:52,895
Some animals take camouflage
a stage further still...

218
00:29:57,215 --> 00:29:59,294
...and these streams in Costa Rica

219
00:29:59,295 --> 00:30:02,055
are home to one of the most remarkable.

220
00:30:12,975 --> 00:30:14,815
A glass frog.

221
00:30:22,655 --> 00:30:28,454
A male, and tiny, no
bigger than your fingernail

222
00:30:28,455 --> 00:30:31,655
and almost entirely transparent...

223
00:30:33,695 --> 00:30:35,255
...as he needs to be.

224
00:30:38,375 --> 00:30:43,534
Almost everything that walks
past here could eat him,

225
00:30:43,535 --> 00:30:45,055
even a cricket.

226
00:30:49,815 --> 00:30:54,174
His best chance is to stay
absolutely still and trust that

227
00:30:54,175 --> 00:30:56,255
the cricket looks right through him.

228
00:31:18,375 --> 00:31:21,254
Danger passed,

229
00:31:21,255 --> 00:31:24,694
and that's just as well,

230
00:31:24,695 --> 00:31:27,775
because he is a father...

231
00:31:30,775 --> 00:31:33,415
...and he's guarding
some very precious eggs.

232
00:31:37,615 --> 00:31:41,214
For the last few weeks,
females, one after the other,

233
00:31:41,215 --> 00:31:44,495
have visited him and entrusted
him with their offspring.

234
00:31:47,775 --> 00:31:50,535
Some are now almost ready to hatch.

235
00:31:54,735 --> 00:31:58,374
There are several clutches on
the leaf, and those at the top,

236
00:31:58,375 --> 00:32:01,735
the most recently laid,
are barely a day old.

237
00:32:07,815 --> 00:32:11,375
But in the jungle, there's
always someone out to get you.

238
00:32:17,615 --> 00:32:22,135
This wasp is a specialist
hunter of frogs' eggs.

239
00:32:24,095 --> 00:32:28,335
It's noticed the wriggling
tadpoles at the bottom of the leaf.

240
00:32:34,015 --> 00:32:35,215
He mustn't move.

241
00:32:36,375 --> 00:32:39,254
The youngest eggs are the most vulnerable,

242
00:32:39,255 --> 00:32:40,855
and he can't guard them all.

243
00:33:00,775 --> 00:33:04,655
But these tadpoles are not as
helpless as they might appear.

244
00:33:12,975 --> 00:33:17,454
Incredibly, the unhatched
tadpoles can sense danger,

245
00:33:17,455 --> 00:33:22,455
and the oldest and strongest wriggle
free and drop into the stream below.

246
00:33:40,255 --> 00:33:42,974
The eggs at the top of the leaf, however,

247
00:33:42,975 --> 00:33:46,694
are still too young to hatch,

248
00:33:46,695 --> 00:33:49,095
and now the wasps know they're there.

249
00:33:53,335 --> 00:33:57,895
But the male's back looks very
like the youngest cluster of eggs...

250
00:34:02,375 --> 00:34:04,775
...and that seems to confuse the wasps.

251
00:34:27,215 --> 00:34:30,575
Using his own body as
a decoy is a huge risk.

252
00:34:31,655 --> 00:34:33,575
The wasp stings could kill him.

253
00:35:01,575 --> 00:35:04,775
He's managed to save most of his young.

254
00:35:09,215 --> 00:35:14,294
He'll have to remain on
guard for another two weeks,

255
00:35:14,295 --> 00:35:19,295
but in the jungle, just surviving
the day can count as a success.

256
00:35:33,775 --> 00:35:35,414
With the coming of the night,

257
00:35:35,415 --> 00:35:39,095
a new cast of jungle
characters takes to the stage.

258
00:35:43,175 --> 00:35:47,455
Flying insects begin to glow
as they search for mates.

259
00:35:51,815 --> 00:35:56,535
Fungi, unlike plants, thrive in
the darkness of the forest floor.

260
00:35:59,615 --> 00:36:03,494
They're hidden until they begin to
develop the incredible structures

261
00:36:03,495 --> 00:36:05,095
with which they reproduce.

262
00:36:08,255 --> 00:36:11,854
Each releases millions
of microscopic spores

263
00:36:11,855 --> 00:36:14,015
that drift invisibly away.

264
00:36:19,575 --> 00:36:24,214
Many have fruiting bodies that reach
upwards to catch any feeble current

265
00:36:24,215 --> 00:36:26,295
there might be in the clammy air.

266
00:36:30,735 --> 00:36:33,774
But this one, as it grows,

267
00:36:33,775 --> 00:36:35,215
becomes luminous.

268
00:36:47,855 --> 00:36:51,495
Why fungi light up has
remained a mystery...

269
00:36:58,295 --> 00:36:59,535
...until now.

270
00:37:08,175 --> 00:37:11,654
Scientists studying the
brightest fungi in the world

271
00:37:11,655 --> 00:37:13,975
think they may have an answer.

272
00:37:19,095 --> 00:37:22,215
Like a beacon, the light attracts insects.

273
00:37:28,855 --> 00:37:30,815
From far and wide.

274
00:37:38,935 --> 00:37:43,494
To this click beetle, a bright
light means only one thing...

275
00:37:43,495 --> 00:37:46,974
a female click beetle,

276
00:37:46,975 --> 00:37:48,495
so he flashes in reply.

277
00:38:00,455 --> 00:38:03,255
But he doesn't get the
reception he was expecting.

278
00:38:08,095 --> 00:38:13,215
Confused, he starts searching for
a female, and that helps the fungus.

279
00:38:15,295 --> 00:38:19,415
By the time he gives up, he's
covered in the fungus's spores.

280
00:38:21,135 --> 00:38:23,734
And, as he continues
his quest for a female,

281
00:38:23,735 --> 00:38:26,935
he carries these spores to
other parts of the forest.

282
00:38:30,455 --> 00:38:35,015
And there are even stranger
things glowing in the jungle night.

283
00:38:38,855 --> 00:38:43,775
These are the multicoloured
lights of a railroad worm.

284
00:38:45,135 --> 00:38:49,935
It's not really a worm, but a
poisonous, caterpillar-like beetle.

285
00:38:53,455 --> 00:38:56,895
The yellow lights warn other
creatures to keep out of its way.

286
00:39:06,375 --> 00:39:09,295
It's hunting for millipedes.

287
00:39:19,375 --> 00:39:24,175
When it finds the trail of one,
it switches off its yellow lights.

288
00:39:30,575 --> 00:39:33,935
Now it only has a red light on its head.

289
00:39:39,415 --> 00:39:42,295
Millipedes can't see red light.

290
00:39:47,375 --> 00:39:52,935
So, to them, the railroad worm in
stealth mode is virtually invisible.

291
00:40:05,535 --> 00:40:08,055
And that is the end of the millipede.

292
00:40:20,495 --> 00:40:24,454
Competition in the jungles
forces animals to specialise

293
00:40:24,455 --> 00:40:27,494
in every aspect of their life,

294
00:40:27,495 --> 00:40:29,055
including courtship.

295
00:40:31,535 --> 00:40:36,134
This has produced some of the most
beautiful and elaborate displays

296
00:40:36,135 --> 00:40:37,615
on the planet.

297
00:40:39,975 --> 00:40:45,414
- (BIRD SQUAWKS)
- A male red bird-of-paradise,

298
00:40:45,415 --> 00:40:49,015
competing to attract a female by dancing.

299
00:40:50,895 --> 00:40:53,255
One has come to survey what's on offer.

300
00:41:11,295 --> 00:41:13,254
She is an independent lady,

301
00:41:13,255 --> 00:41:18,454
and she will select whichever
male takes her fancy.

302
00:41:18,455 --> 00:41:20,655
(BIRDS SQUAWKING)

303
00:41:34,415 --> 00:41:35,815
She makes her choice.

304
00:41:54,295 --> 00:41:57,255
But now she doesn't seem quite so sure.

305
00:42:05,575 --> 00:42:10,495
No? Perhaps he's just a little too keen.

306
00:42:23,815 --> 00:42:26,095
Maybe he'll have better luck tomorrow.

307
00:42:35,335 --> 00:42:38,695
Red birds-of-paradise
display in the treetops.

308
00:42:41,935 --> 00:42:45,975
Other members of the family dance
in the gloom of the forest floor.

309
00:42:49,295 --> 00:42:52,655
This is a Wilson's
bird-of-paradise.

310
00:42:54,175 --> 00:42:57,495
He's brightly coloured, but
about the size of a sparrow.

311
00:43:01,215 --> 00:43:06,014
He's lived most of his life
alone, but now he's an adult,

312
00:43:06,015 --> 00:43:08,615
and he too needs to attract a mate.

313
00:43:13,135 --> 00:43:16,055
This little patch of
light might help him do so.

314
00:43:22,535 --> 00:43:25,654
First, he tidies things up.

315
00:43:25,655 --> 00:43:30,654
Showing off in this jumble
of leaves wouldn't be easy,

316
00:43:30,655 --> 00:43:34,975
and his beauty will stand out
better against a plain background.

317
00:43:43,015 --> 00:43:47,654
He doesn't want bright leaves
to divert a visitor's attention.

318
00:43:47,655 --> 00:43:49,055
They all need to go.

319
00:43:52,815 --> 00:43:54,255
Even the green ones.

320
00:43:57,135 --> 00:43:58,975
Especially the green ones.

321
00:44:08,575 --> 00:44:11,094
His stage is set.

322
00:44:11,095 --> 00:44:14,574
A central pole, and a
little patch of light.

323
00:44:14,575 --> 00:44:15,615
It's perfect.

324
00:44:19,695 --> 00:44:23,014
And now, he must hope
a female hears his call.

325
00:44:23,015 --> 00:44:24,695
(HIGH-PITCHED SQUAWKING)

326
00:44:34,575 --> 00:44:36,775
He can wait here for weeks on end.

327
00:44:46,695 --> 00:44:48,695
At last, a female.

328
00:44:51,495 --> 00:44:53,775
Time to take up position.

329
00:44:56,175 --> 00:44:59,695
She will judge him by the
brightness of his feathers.

330
00:45:05,415 --> 00:45:08,174
But for the female to see him at his best,

331
00:45:08,175 --> 00:45:13,774
he needs her to perch
directly above his stage,

332
00:45:13,775 --> 00:45:15,175
under the light.

333
00:45:18,735 --> 00:45:22,015
This might be his only chance to shine.

334
00:45:28,575 --> 00:45:33,094
Now, when she's looking directly
down on him, he reveals a display

335
00:45:33,095 --> 00:45:34,935
for her eyes only.

336
00:45:40,975 --> 00:45:43,414
In the gloom of the forest floor,

337
00:45:43,415 --> 00:45:47,215
he is a dazzling blaze of iridescent green.

338
00:45:48,975 --> 00:45:51,775
The brightest leaf in the forest.

339
00:46:00,295 --> 00:46:01,895
And that does the trick.

340
00:46:12,015 --> 00:46:16,254
Each animal must find its own
way of surviving the competition

341
00:46:16,255 --> 00:46:17,775
of the jungle.

342
00:46:30,455 --> 00:46:35,054
This crowded world is so full of
invention that almost all kinds

343
00:46:35,055 --> 00:46:39,415
of animals on land can trace
their origins back here...

344
00:46:44,375 --> 00:46:45,975
...including us.

345
00:46:49,455 --> 00:46:54,255
These forests in Madagascar are
home to one of our distant cousins.

346
00:46:58,415 --> 00:47:03,254
This female indri has fought to
keep this particular patch of forest

347
00:47:03,255 --> 00:47:06,654
safe for herself and her family.

348
00:47:06,655 --> 00:47:10,055
(HIGH-PITCHED SHRIEKS)

349
00:47:16,375 --> 00:47:20,494
Every morning, the family
come together to sing,

350
00:47:20,495 --> 00:47:24,455
their way of reminding others
that this is their home.

351
00:47:30,775 --> 00:47:34,214
Indri are so closely adapted to living here

352
00:47:34,215 --> 00:47:37,095
that now they can live nowhere else.

353
00:47:40,975 --> 00:47:46,134
For them and the billions of animals
with whom they share their home,

354
00:47:46,135 --> 00:47:48,655
the jungle is a sanctuary.

355
00:47:52,975 --> 00:47:54,815
But this is changing.

356
00:47:58,855 --> 00:48:02,734
Even in the ten years since the
head of this family was born,

357
00:48:02,735 --> 00:48:06,774
one million hectares of the
rainforest have been destroyed

358
00:48:06,775 --> 00:48:10,334
in Madagascar alone,

359
00:48:10,335 --> 00:48:14,055
and, with it, half the indri
families that once lived there.

360
00:48:19,695 --> 00:48:24,334
The local people say the indris
are our brothers and their song is

361
00:48:24,335 --> 00:48:28,415
a call to remind us that we,
too, once depended on the jungle.

362
00:48:37,655 --> 00:48:41,815
This Eden is still a
place of wonder and magic.

363
00:48:47,095 --> 00:48:50,855
Something, surely, worth protecting.

364
00:49:08,655 --> 00:49:12,454
Jungles are still some of the
least explored places on Earth,

365
00:49:12,455 --> 00:49:14,854
and with good reason.

366
00:49:14,855 --> 00:49:16,815
They are testing places to work.

367
00:49:20,495 --> 00:49:23,094
Here in the flooded forests of Brazil,

368
00:49:23,095 --> 00:49:27,535
the team are on the trail of a newly
discovered species of river dolphin.

369
00:49:29,215 --> 00:49:33,095
So little is known about it that
just finding it will be a challenge.

370
00:49:34,735 --> 00:49:40,774
Their base for five weeks is a hut
on the only bit of dry land around,

371
00:49:40,775 --> 00:49:43,134
but it's already occupied.

372
00:49:43,135 --> 00:49:45,694
It appears someone's been making a nest.

373
00:49:45,695 --> 00:49:47,014
A resident rat.

374
00:49:47,015 --> 00:49:51,134
- Hello, little rat.
- And on the food cupboard...

375
00:49:51,135 --> 00:49:53,975
Hello. Are you a bit shy?

376
00:49:58,375 --> 00:50:02,055
If the housemates are hostile,
the hitchhikers are even worse.

377
00:50:04,495 --> 00:50:06,055
A large spider.

378
00:50:07,295 --> 00:50:08,535
Oh, my God.

379
00:50:09,935 --> 00:50:13,774
And a colony of aggressive
red ants looking for a ride.

380
00:50:13,775 --> 00:50:15,814
Shall we knock into them?

381
00:50:15,815 --> 00:50:19,534
They'll board the boat
like a bunch of pirates,

382
00:50:19,535 --> 00:50:20,975
and they'll gnaw our faces off.

383
00:50:24,295 --> 00:50:26,054
That might not be quite true,

384
00:50:26,055 --> 00:50:29,535
but intimidating animals are
the least of their problems.

385
00:50:31,975 --> 00:50:34,414
The flooded forest is not only vast,

386
00:50:34,415 --> 00:50:38,974
it's impenetrable, and this new
species of dolphin could be anywhere

387
00:50:38,975 --> 00:50:43,215
in 150,000 square miles
of tangled treetops.

388
00:50:45,535 --> 00:50:47,015
But the crew have a plan.

389
00:50:48,295 --> 00:50:51,814
Dolphins use sound to find their
way through the flooded forest

390
00:50:51,815 --> 00:50:53,855
by making clicks. Sonar.

391
00:50:54,975 --> 00:50:58,894
Waterproof microphones allow the
crew to eavesdrop on the dolphins,

392
00:50:58,895 --> 00:51:00,455
and so follow them.

393
00:51:04,295 --> 00:51:06,215
But that's easier said than done.

394
00:51:10,375 --> 00:51:12,854
So, this is the clear path.

395
00:51:12,855 --> 00:51:15,655
Can you see it? There.

396
00:51:22,775 --> 00:51:26,294
It takes them a week to get their
first glimpse of this new species,

397
00:51:26,295 --> 00:51:28,855
and even then, it lasts less than a second.

398
00:51:32,215 --> 00:51:34,575
There appears to be only one dolphin.

399
00:51:38,655 --> 00:51:42,415
And, frustratingly, it can pop
up anywhere without warning.

400
00:51:45,335 --> 00:51:48,254
Been looking through the water
and seeing bodies kind of appear

401
00:51:48,255 --> 00:51:52,055
out of the murk, and then disappear again.

402
00:51:54,975 --> 00:51:58,815
Eventually, the dolphin leads the
crew to an open gap in the forest.

403
00:52:09,455 --> 00:52:11,895
We made it! Yay!

404
00:52:15,255 --> 00:52:18,575
Here, at last, there may be a chance
of getting something in the can.

405
00:52:26,095 --> 00:52:30,695
Their first shot, but again, a
single breath, and then it's gone.

406
00:52:35,775 --> 00:52:38,814
- Hello, you.
- With the dolphin as close as this,

407
00:52:38,815 --> 00:52:41,334
the crew can try a different technique...

408
00:52:41,335 --> 00:52:43,895
towing an underwater
camera behind the boat.

409
00:52:47,495 --> 00:52:50,295
Dolphin literally just
came up parallel to it.

410
00:52:51,415 --> 00:52:54,814
The problem is that the water
is so murky, that the dolphin is

411
00:52:54,815 --> 00:52:57,855
almost invisible, even when
right next to the camera.

412
00:53:05,255 --> 00:53:07,854
However, now the dolphin
is in this channel,

413
00:53:07,855 --> 00:53:09,695
the crew can try a different tack.

414
00:53:18,495 --> 00:53:21,055
Michael Sanderson is a drone operator.

415
00:53:24,295 --> 00:53:26,454
As long as the dolphin's in open water,

416
00:53:26,455 --> 00:53:28,775
it might be possible to
follow it from the air.

417
00:53:32,815 --> 00:53:35,454
We've worked out the
dolphins seem to be here,

418
00:53:35,455 --> 00:53:39,495
and we can do the drone work,
so this is our kind of best bet.

419
00:53:40,495 --> 00:53:43,214
Leaving Michael and his
drone on the sand spit,

420
00:53:43,215 --> 00:53:45,175
the crew head back to open water.

421
00:53:46,415 --> 00:53:49,135
But this is called the
flooded forest for a reason.

422
00:53:52,175 --> 00:53:54,174
The rain here can be torrential,

423
00:53:54,175 --> 00:53:56,974
and although storms normally pass quickly,

424
00:53:56,975 --> 00:53:59,175
this one is clearly not a normal storm.

425
00:54:04,615 --> 00:54:06,494
Is it not working?

426
00:54:06,495 --> 00:54:09,414
The motor has broken, and
with the boat flooding,

427
00:54:09,415 --> 00:54:10,935
the crew must head for the bank.

428
00:54:17,255 --> 00:54:19,134
It looked like the
rainstorm was going to pass,

429
00:54:19,135 --> 00:54:22,334
and it hasn't passed at
all. It's very, very heavy,

430
00:54:22,335 --> 00:54:24,655
and I'm soaked through to the skin.

431
00:54:28,655 --> 00:54:32,334
They're stranded, the
kit is getting drenched,

432
00:54:32,335 --> 00:54:35,694
trees are falling, and Michael
is trapped somewhere down-river.

433
00:54:35,695 --> 00:54:39,534
This is the hardest rain
I've ever seen in my life.

434
00:54:39,535 --> 00:54:43,214
- It's incredible.
- I'm hoping Michael's all right.

435
00:54:43,215 --> 00:54:46,494
And there's been tree fall
all up around behind us.

436
00:54:46,495 --> 00:54:49,374
Michael's down there on
a tiny little sand spit,

437
00:54:49,375 --> 00:54:52,615
with the other boat,
with his opticopter out.

438
00:54:53,855 --> 00:54:55,255
Kind of scary.

439
00:54:57,655 --> 00:54:58,894
After two hours,

440
00:54:58,895 --> 00:55:02,534
a break in the storm gives Michael
a chance to rejoin the team.

441
00:55:02,535 --> 00:55:06,614
Just got caught in one of the
heaviest storms I've ever seen.

442
00:55:06,615 --> 00:55:11,734
Got up to this much water on
the tarp, and the other one, so

443
00:55:11,735 --> 00:55:14,334
I don't know if this is
going to live any more,

444
00:55:14,335 --> 00:55:16,974
because that was on the floor.

445
00:55:16,975 --> 00:55:20,294
It looks like it's game over for the drone.

446
00:55:20,295 --> 00:55:22,415
Yeah, it was pretty scary, wasn't it?

447
00:55:24,455 --> 00:55:28,255
Over the next 12 hours, the
storm returns again and again.

448
00:55:29,855 --> 00:55:31,614
If this bad weather continues,

449
00:55:31,615 --> 00:55:34,575
the crew may not be able to
get back out to the dolphin.

450
00:55:40,175 --> 00:55:42,894
The next morning,

451
00:55:42,895 --> 00:55:46,215
clear skies, and the
drone might be fixable.

452
00:55:47,215 --> 00:55:50,694
But the longer it takes, the
more chance that the dolphin

453
00:55:50,695 --> 00:55:53,814
will have returned to the flooded forest,

454
00:55:53,815 --> 00:55:55,695
and then it'll be back to square one.

455
00:55:58,415 --> 00:56:00,455
But finally, their luck is in.

456
00:56:02,735 --> 00:56:04,335
The dolphin is still there.

457
00:56:06,975 --> 00:56:09,294
For the first time, they
have a chance to film

458
00:56:09,295 --> 00:56:12,614
from the water and the
air, and finally discover

459
00:56:12,615 --> 00:56:15,015
what this elusive animal is really doing.

460
00:56:16,695 --> 00:56:19,814
They were in the boat and they
were looking around and going,

461
00:56:19,815 --> 00:56:22,054
"Yeah, there are some bubbles."

462
00:56:22,055 --> 00:56:25,934
We were flying with the drone
and we could see dolphins,

463
00:56:25,935 --> 00:56:30,574
and while they thought they could
only see one dolphin, we saw five.

464
00:56:30,575 --> 00:56:32,694
And they had no idea.

465
00:56:32,695 --> 00:56:35,934
The crew are surprised to find
these dolphins aren't solitary,

466
00:56:35,935 --> 00:56:38,694
but come together to hunt as a team.

467
00:56:38,695 --> 00:56:41,854
You're starting to see stuff with
the drone that you suddenly go,

468
00:56:41,855 --> 00:56:44,174
"I thought there was
one dolphin there," and

469
00:56:44,175 --> 00:56:47,974
then you count that there are five
and then you're looking in one place

470
00:56:47,975 --> 00:56:50,694
and they're all behind
you, laughing at you.

471
00:56:50,695 --> 00:56:54,134
This new perspective has
given the crew a first glimpse

472
00:56:54,135 --> 00:56:56,174
into a mysterious jungle animal

473
00:56:56,175 --> 00:56:59,655
in one of the least-known
corners of the Earth.

474
00:57:08,135 --> 00:57:12,615
Next time... a land of extremes
that pushes life to the limit.

475
00:57:14,855 --> 00:57:18,495
Animals have extraordinary ways of
dealing with the hostile conditions.

476
00:57:20,215 --> 00:57:24,694
Creating the most epic
survival stories on Earth.

477
00:57:24,695 --> 00:57:26,335
These are deserts.
