1
00:00:00,000 --> 00:00:01,820
(soft music)

2
00:00:01,820 --> 00:00:04,800
On the bridge between North and South America,

3
00:00:04,800 --> 00:00:08,190
lies one of the most diverse ecosystems of its size

4
00:00:08,190 --> 00:00:09,880
on the planet.

5
00:00:09,880 --> 00:00:12,130
Its biodiversity is unparalleled

6
00:00:12,130 --> 00:00:15,100
and its beauty is unmatched.

7
00:00:15,100 --> 00:00:17,915
Costa Rica is truly a bastion for wildlife

8
00:00:17,915 --> 00:00:18,748
like no other.

9
00:00:18,748 --> 00:00:21,498
(dramatic music)

10
00:00:24,656 --> 00:00:27,340
Hi, I'm Danielle Dufault and you're watching Animalogic.

11
00:00:27,340 --> 00:00:29,433
(soft music)

12
00:00:29,433 --> 00:00:30,266
(birds chirping)

13
00:00:30,266 --> 00:00:33,070
Today, we are in Corcovado National Park in Costa Rica.

14
00:00:33,070 --> 00:00:35,829
This park is in the middle of one of the most

15
00:00:35,829 --> 00:00:39,174
biologically intense rainforests in the world.

16
00:00:39,174 --> 00:00:42,170
(soft music)

17
00:00:42,170 --> 00:00:44,610
Within a space of about 10 meters,

18
00:00:44,610 --> 00:00:47,277
you might see a crocodile, a bull shark,

19
00:00:47,277 --> 00:00:50,233
a spider monkey, and a kingfisher.

20
00:00:53,550 --> 00:00:56,520
Corcovado is one of the most remote rainforests

21
00:00:56,520 --> 00:00:58,270
in Central America.

22
00:00:58,270 --> 00:01:01,620
You can only get here by boat or by small plane

23
00:01:01,620 --> 00:01:05,463
and the only roads are the ones built by leafcutter ants.

24
00:01:08,160 --> 00:01:10,380
The perkiest residents of the park

25
00:01:10,380 --> 00:01:11,953
are the coatimundis.

26
00:01:13,960 --> 00:01:16,740
With their tails pointed directly upwards,

27
00:01:16,740 --> 00:01:19,473
coatis are easy to spot off in the distance.

28
00:01:21,550 --> 00:01:23,650
Unlike their cousins the raccoons,

29
00:01:23,650 --> 00:01:26,740
they are diurnal and spend their days out and about,

30
00:01:26,740 --> 00:01:28,233
scrounging for food.

31
00:01:31,700 --> 00:01:34,650
They use their long and flexible nose to poke around

32
00:01:34,650 --> 00:01:37,260
little rocks in search of fruit, grubs,

33
00:01:37,260 --> 00:01:38,603
and other insects.

34
00:01:40,635 --> 00:01:42,340
(animal crying)

35
00:01:42,340 --> 00:01:45,420
Deeper in the jungle live the largest land mammals

36
00:01:45,420 --> 00:01:48,512
in Central and South America, the tapir.

37
00:01:48,512 --> 00:01:51,179
(African music)

38
00:01:53,470 --> 00:01:55,960
Measuring up to two and a half meters long

39
00:01:55,960 --> 00:01:58,791
and weighing up to 300 kilograms,

40
00:01:58,791 --> 00:02:02,290
tapirs are true giants.

41
00:02:02,290 --> 00:02:05,330
Their nose and upper lip combine into a mini-trunk

42
00:02:05,330 --> 00:02:07,993
that functions much like an elephant's trunk.

43
00:02:11,040 --> 00:02:13,030
They have incredibly powerful jaws

44
00:02:13,030 --> 00:02:16,253
and if they bit you, they might take your arm off.

45
00:02:19,460 --> 00:02:21,440
If you're thinking that they look like they belong

46
00:02:21,440 --> 00:02:24,333
in an Ice Age movie, it's because they do.

47
00:02:25,429 --> 00:02:27,850
Tapirs are one of the most primitive, large mammals

48
00:02:27,850 --> 00:02:29,850
in the world and have remained

49
00:02:29,850 --> 00:02:33,830
unchanged for roughly 20 million years.

50
00:02:33,830 --> 00:02:35,000
If we're not careful,

51
00:02:35,000 --> 00:02:37,233
they won't make it the next 20 million.

52
00:02:38,100 --> 00:02:40,970
Endangered, there are less than 6,000

53
00:02:40,970 --> 00:02:43,183
Baird's tapirs left in the wild.

54
00:02:46,233 --> 00:02:48,420
(soft music)

55
00:02:48,420 --> 00:02:52,260
Tapirs can eat up to 35 kilograms of food a day

56
00:02:52,260 --> 00:02:55,230
and because of this, they are a critical species

57
00:02:55,230 --> 00:02:57,523
for spreading seeds throughout the jungle.

58
00:02:59,920 --> 00:03:03,140
Tapirs spend their mornings soaking in mud baths,

59
00:03:03,140 --> 00:03:06,610
often with several companions like the basilisk lizard

60
00:03:08,948 --> 00:03:13,763
but life for a tapir isn't always so relaxing.

61
00:03:14,990 --> 00:03:17,470
While being so large means that they have

62
00:03:18,506 --> 00:03:20,720
very few predators, their main predators happen to be

63
00:03:20,720 --> 00:03:24,833
the second largest land mammal in South and Central America.

64
00:03:27,570 --> 00:03:28,723
The jaguar.

65
00:03:30,653 --> 00:03:32,460
(dramatic music)

66
00:03:32,460 --> 00:03:35,490
Hoping to catch the tapir in its morning mud bath,

67
00:03:35,490 --> 00:03:38,493
the jaguar silently approaches.

68
00:03:41,850 --> 00:03:43,703
But it's not silent enough.

69
00:03:54,250 --> 00:03:56,943
The tapir will live to soak another day.

70
00:04:00,520 --> 00:04:03,520
Up in the trees, the faces of Corcovado

71
00:04:03,520 --> 00:04:05,203
are entirely different.

72
00:04:07,050 --> 00:04:10,480
Perhaps the most charismatic of all Corcovado residents

73
00:04:10,480 --> 00:04:11,740
are the monkeys.

74
00:04:11,740 --> 00:04:14,794
Capuchin, howler, squirrel monkeys all live here

75
00:04:14,794 --> 00:04:16,593
in the tree canopy.

76
00:04:18,030 --> 00:04:21,013
The second largest of these are the spider monkeys.

77
00:04:22,980 --> 00:04:24,950
Like many New World monkeys,

78
00:04:24,950 --> 00:04:27,870
they have prehensile tails which are very helpful

79
00:04:27,870 --> 00:04:28,983
for getting around.

80
00:04:30,200 --> 00:04:32,693
Especially with a newborn in toe.

81
00:04:34,580 --> 00:04:37,480
Spider monkeys get their name from their long and lanky

82
00:04:37,480 --> 00:04:41,040
limbs which may make them look like angrily teenagers

83
00:04:41,040 --> 00:04:44,120
but they make swinging through the trees a breeze

84
00:04:44,120 --> 00:04:46,083
even without opposable thumbs.

85
00:04:47,374 --> 00:04:49,944
(monkey crying)

86
00:04:49,944 --> 00:04:52,410
The common ancestor to all of these New World monkeys

87
00:04:52,410 --> 00:04:55,090
came here from Africa millions of years ago

88
00:04:55,090 --> 00:04:57,100
but nobody knows for sure how.

89
00:04:57,100 --> 00:05:00,040
The most accepted theory is that they were transported here

90
00:05:00,040 --> 00:05:04,230
on natural rafts after a massive flooding event in Africa.

91
00:05:04,230 --> 00:05:07,540
Despite their strong numbers in the Osa Peninsula,

92
00:05:07,540 --> 00:05:10,690
spider monkeys are endangered and every day

93
00:05:10,690 --> 00:05:14,373
face increasing threats from deforestation and hunting.

94
00:05:16,800 --> 00:05:19,640
Spider monkeys spend their days in large groups,

95
00:05:19,640 --> 00:05:21,893
forging for fruits in the treetops.

96
00:05:25,380 --> 00:05:28,480
Their numbers help deter their arboreal predators

97
00:05:28,480 --> 00:05:29,604
like the margay.

98
00:05:29,604 --> 00:05:32,021
(soft music)

99
00:05:38,140 --> 00:05:40,560
Margays are incredibly skilled climbers

100
00:05:40,560 --> 00:05:42,823
and primarily hunt in the tree canopy.

101
00:05:43,890 --> 00:05:45,430
But for the right meal,

102
00:05:45,430 --> 00:05:48,645
they will make their way to the jungle floor.

103
00:05:48,645 --> 00:05:52,639
In this case, a rat.

104
00:05:52,639 --> 00:05:54,569
(rat squealing)

105
00:05:54,569 --> 00:05:56,155
(dramatic music)

106
00:05:56,155 --> 00:05:57,481
She puts up a fight.

107
00:05:57,481 --> 00:06:00,148
(rat squealing)

108
00:06:06,780 --> 00:06:09,997
But, in the end, is no match for the margay.

109
00:06:11,970 --> 00:06:14,510
Monkeys aren't the only ones who find safety

110
00:06:14,510 --> 00:06:15,743
in the treetops.

111
00:06:17,102 --> 00:06:20,185
(upbeat funky music)

112
00:06:21,366 --> 00:06:23,700
Tamanduas are as comfortable in the tree canopy

113
00:06:23,700 --> 00:06:25,800
as they are on the ground.

114
00:06:25,800 --> 00:06:28,410
They are a type of anteater and spend their days

115
00:06:28,410 --> 00:06:31,170
looking for ants above and below.

116
00:06:31,170 --> 00:06:33,440
They are excellent climbers.

117
00:06:33,440 --> 00:06:36,090
They have a long prehensile tail which is hairless

118
00:06:36,090 --> 00:06:38,210
on the bottom, essentially acting like

119
00:06:38,210 --> 00:06:40,643
an extra hand to grab branches with.

120
00:06:42,050 --> 00:06:44,470
Though sometimes it's easier to get down

121
00:06:44,470 --> 00:06:45,763
just by sliding.

122
00:06:47,350 --> 00:06:49,290
They have a long sticky tongue

123
00:06:49,290 --> 00:06:52,070
which they use to pick up ants and termites.

124
00:06:52,070 --> 00:06:55,503
Sometimes over 9,000 in a single day.

125
00:06:56,600 --> 00:06:58,820
Their coat is thick and coarse

126
00:06:58,820 --> 00:07:02,803
and it helps keep ants, termites, and other insects at bay.

127
00:07:04,960 --> 00:07:07,280
There's nothing worse than flies biting you

128
00:07:07,280 --> 00:07:08,653
while you're trying to nap.

129
00:07:09,710 --> 00:07:13,503
Insects or no, his nap is about to be interrupted.

130
00:07:14,766 --> 00:07:17,516
(dramatic music)

131
00:07:21,200 --> 00:07:23,813
A puma lies in wait at the base of the tree.

132
00:07:31,930 --> 00:07:34,563
But the tamandua has a trick up his sleeve.

133
00:07:40,010 --> 00:07:43,960
When threatened, as a last resort, tamandua will omit

134
00:07:43,960 --> 00:07:45,233
a horrible smell.

135
00:07:46,470 --> 00:07:49,740
(dramatic music)

136
00:07:49,740 --> 00:07:52,863
It works and the puma skulks off.

137
00:07:54,468 --> 00:07:55,740
(dramatic music)

138
00:07:55,740 --> 00:07:58,630
Closer to the ground, the jungles of Costa Rica

139
00:07:58,630 --> 00:08:02,860
are ruled by a wide variety of amphibians and reptiles

140
00:08:02,860 --> 00:08:06,470
but to find them, we'll have to look very closely.

141
00:08:06,470 --> 00:08:10,910
Crocodiles, caiman, tree frogs, basilisk lizards,

142
00:08:10,910 --> 00:08:14,793
iguanas, and many others call this jungle home.

143
00:08:17,766 --> 00:08:20,349
(upbeat music)

144
00:08:21,850 --> 00:08:24,670
The wildlife found here is denser than any other place

145
00:08:24,670 --> 00:08:27,623
on the planet and it's a fairly recent mix.

146
00:08:32,370 --> 00:08:33,980
Four million years ago during the

147
00:08:33,980 --> 00:08:37,473
Great South American Exchange, the North and South Americas

148
00:08:37,473 --> 00:08:40,910
bridged which created a great exchange of fauna

149
00:08:40,910 --> 00:08:44,112
from the North to the South and the South to the North.

150
00:08:44,112 --> 00:08:47,530
This Great American Biotic Interchange

151
00:08:47,530 --> 00:08:50,990
saw North American species like cougars, tapirs,

152
00:08:50,990 --> 00:08:53,631
and deer cross over into South America.

153
00:08:53,631 --> 00:08:58,570
While South American species like armadillos,

154
00:08:58,570 --> 00:09:01,700
tamanduas, and poison dart frogs made their way

155
00:09:01,700 --> 00:09:04,194
into Central and North America.

156
00:09:04,194 --> 00:09:07,703
The North American species were much better off

157
00:09:07,703 --> 00:09:11,250
'cause many of the species coming from the South

158
00:09:11,250 --> 00:09:14,160
were not able to compete with animals in the North

159
00:09:14,160 --> 00:09:17,730
occupying similar niches and were unable to diversify

160
00:09:17,730 --> 00:09:21,213
to adapt to this change in territory and climate.

161
00:09:22,137 --> 00:09:23,720
(soft music)

162
00:09:23,720 --> 00:09:27,060
The poison dart frog, for example, only made it as far North

163
00:09:27,060 --> 00:09:28,700
as Central America.

164
00:09:28,700 --> 00:09:31,080
Unlike many other species of frog,

165
00:09:31,080 --> 00:09:33,965
poison darts make no effort at all to blend in

166
00:09:33,965 --> 00:09:37,070
and they exhibit some of the most brilliant colors

167
00:09:37,070 --> 00:09:38,728
in the animal world.

168
00:09:38,728 --> 00:09:41,770
This is called aposematism.

169
00:09:41,770 --> 00:09:44,070
A display of bright colors to warn predators

170
00:09:44,070 --> 00:09:48,040
that they're poisonous and they're quite poisonous.

171
00:09:48,040 --> 00:09:50,270
The golden poison frog has enough poison

172
00:09:50,270 --> 00:09:52,650
to kill 10 adult men.

173
00:09:52,650 --> 00:09:56,036
But the interesting thing is, they don't make their poison.

174
00:09:56,036 --> 00:09:58,730
It comes entirely from their diet.

175
00:09:58,730 --> 00:10:01,400
Likely from eating fire ants and other insects which,

176
00:10:01,400 --> 00:10:04,163
themselves, ingest plant poisons.

177
00:10:05,600 --> 00:10:08,360
Poison darts share the jungle with possibly the most

178
00:10:08,360 --> 00:10:11,034
iconic frog in the world.

179
00:10:11,034 --> 00:10:13,410
(dramatic music)

180
00:10:13,410 --> 00:10:15,063
The red-eyed tree frog.

181
00:10:22,570 --> 00:10:26,530
Unlike poison darts, red-eyed tree frogs aren't poisonous

182
00:10:26,530 --> 00:10:28,123
despite their bright coloring.

183
00:10:29,160 --> 00:10:30,690
When targeted by a predator,

184
00:10:30,690 --> 00:10:33,500
they'll flash their bright red eyes at their attacker.

185
00:10:33,500 --> 00:10:36,010
This may give the predator some pause,

186
00:10:36,010 --> 00:10:37,943
allowing the frog to jump away.

187
00:10:38,900 --> 00:10:41,693
This strategy is called startle coloration.

188
00:10:43,430 --> 00:10:45,870
Their eyes sit very high up on their heads

189
00:10:45,870 --> 00:10:48,070
and are quite huge and bulging.

190
00:10:48,070 --> 00:10:51,503
This gives them near 360 degree vision.

191
00:10:53,520 --> 00:10:55,680
But they have an extra use.

192
00:10:55,680 --> 00:10:57,483
They help with swallowing.

193
00:10:58,760 --> 00:11:01,980
Red-eyed tree frogs snag prey with their quick fire tongues

194
00:11:01,980 --> 00:11:03,653
and then swallow them whole.

195
00:11:05,500 --> 00:11:07,830
To help push their prey down their throat,

196
00:11:07,830 --> 00:11:11,030
their eyes recede, giving their meal an extra push

197
00:11:11,030 --> 00:11:12,093
into their bellies.

198
00:11:14,137 --> 00:11:16,554
(soft music)

199
00:11:26,592 --> 00:11:29,342
(dramatic music)

200
00:11:34,640 --> 00:11:37,790
Costa Rica is home to a wide variety of frogs

201
00:11:37,790 --> 00:11:40,110
and one of their local endemic residents

202
00:11:40,110 --> 00:11:43,103
is the beautiful blue-sided tree frog.

203
00:11:46,520 --> 00:11:49,170
Endangered, they've seen a population decline

204
00:11:49,170 --> 00:11:52,223
of 50% since the early 1990s.

205
00:11:53,676 --> 00:11:55,210
(dramatic music)

206
00:11:55,210 --> 00:11:58,298
Their biggest threats are coming from competing

207
00:11:58,298 --> 00:12:01,470
invasive fish, The International Pet Trade, and a fungal

208
00:12:01,470 --> 00:12:04,543
disease that prevents them from being able to breathe.

209
00:12:07,630 --> 00:12:10,740
Fortunately, due to conservation efforts in Costa Rica,

210
00:12:10,740 --> 00:12:13,273
their populations are currently stable.

211
00:12:14,499 --> 00:12:17,249
(dramatic music)

212
00:12:19,770 --> 00:12:21,610
Tree frogs find themselves prey

213
00:12:21,610 --> 00:12:23,563
to a lot of different predators.

214
00:12:27,410 --> 00:12:30,233
A vine snake spots the tree frog from above.

215
00:12:32,960 --> 00:12:35,093
The tree frog is yet unaware.

216
00:12:38,205 --> 00:12:41,205
(wildlife chirping)

217
00:12:43,970 --> 00:12:45,403
The snake strikes.

218
00:12:46,810 --> 00:12:48,440
But she's too loud.

219
00:12:48,440 --> 00:12:51,093
The tree frog hears her coming and jumps.

220
00:12:53,300 --> 00:12:55,993
Though their jumps don't always go so well.

221
00:13:02,880 --> 00:13:04,380
Lucky for the vine snake,

222
00:13:04,380 --> 00:13:07,003
their next meal is always right around the corner.

223
00:13:09,770 --> 00:13:10,833
(upbeat music)

224
00:13:10,833 --> 00:13:12,530
Vine snakes aren't the only predators slithering

225
00:13:12,530 --> 00:13:14,833
through the jungles of Central America.

226
00:13:15,670 --> 00:13:20,315
Much larger and much deadlier, the boa constrictor

227
00:13:20,315 --> 00:13:24,253
lies in wait in the dark underbrush for its next meal.

228
00:13:26,460 --> 00:13:29,202
Something a bit bigger than a tree frog,

229
00:13:29,202 --> 00:13:32,223
a black spiny-tailed iguana.

230
00:13:34,660 --> 00:13:38,580
These lizards live in colonies dominated by a large male.

231
00:13:38,580 --> 00:13:41,140
They spend their days basking in the sunlight,

232
00:13:41,140 --> 00:13:43,963
always keeping an eye out for hawks on the hunt.

233
00:13:48,910 --> 00:13:51,373
But it's not a hawk that's eyeing this iguana.

234
00:13:54,570 --> 00:13:57,840
Sensing the boa, the iguana asserts its dominance

235
00:13:57,840 --> 00:13:59,633
by showing off its dewlap.

236
00:14:00,640 --> 00:14:02,563
The boa is unperturbed.

237
00:14:03,660 --> 00:14:05,940
The iguana tries to lose the boa in the trees

238
00:14:09,069 --> 00:14:10,878
but isn't quick enough.

239
00:14:10,878 --> 00:14:12,479
I'll be right here.

240
00:14:12,479 --> 00:14:16,683
Right on the water, right here?

241
00:14:16,683 --> 00:14:19,053
But such is life in the jungle.

242
00:14:20,904 --> 00:14:23,300
(upbeat music)

243
00:14:23,300 --> 00:14:27,290
Costa Rica is home to an amazing variety of wildlife

244
00:14:27,290 --> 00:14:31,283
but perhaps none are more beautiful than the birds.

245
00:14:41,360 --> 00:14:44,050
Central and South America have a disproportionately

246
00:14:44,995 --> 00:14:46,480
large number of avian species.

247
00:14:46,480 --> 00:14:50,783
3,500 out of 10,000 avian species live here.

248
00:14:53,470 --> 00:14:55,940
In Costa Rica alone, you can find

249
00:14:55,940 --> 00:14:58,990
920 different species of bird.

250
00:14:58,990 --> 00:15:02,390
That's 10% of the entire world's bird life

251
00:15:02,390 --> 00:15:05,113
found in a country smaller than West Virginia.

252
00:15:06,370 --> 00:15:09,370
Here in Corcovado, you can see birds such as toucans,

253
00:15:09,370 --> 00:15:11,233
macaws, and curassow.

254
00:15:14,654 --> 00:15:16,208
Toucans are probably the most iconic

255
00:15:16,208 --> 00:15:18,373
of the country's avian residents.

256
00:15:19,860 --> 00:15:23,010
Their bills can be four times the size of their head

257
00:15:23,010 --> 00:15:26,083
and often as long as their bodies.

258
00:15:26,083 --> 00:15:28,750
(toucan cawing)

259
00:15:34,370 --> 00:15:37,620
These long colorful bills are not only an effective way

260
00:15:37,620 --> 00:15:39,940
to attract mates, but they use them to

261
00:15:39,940 --> 00:15:43,320
intimidate other birds, grab fruit at the end of branches

262
00:15:43,320 --> 00:15:45,510
too weak to support their body weight,

263
00:15:45,510 --> 00:15:48,312
and to dig meals out of small crevasses.

264
00:15:48,312 --> 00:15:52,290
(upbeat playful music)

265
00:15:52,290 --> 00:15:55,080
They have incredible control over their beaks

266
00:15:55,080 --> 00:15:57,090
and during mating, they will pass fruit

267
00:15:57,090 --> 00:15:59,123
to one another as a form of courtship.

268
00:16:01,790 --> 00:16:04,103
Or they'll tap their long bills together.

269
00:16:06,370 --> 00:16:10,350
Unfortunately, toucans probably don't follow their noses

270
00:16:10,350 --> 00:16:11,810
all that much.

271
00:16:11,810 --> 00:16:15,193
As like most birds, they have a very poor sense of smell.

272
00:16:16,360 --> 00:16:19,450
Yellow throated toucans are the largest of the toucans

273
00:16:19,450 --> 00:16:23,360
found in Costa Rica and are known to be bullies.

274
00:16:23,360 --> 00:16:25,770
These two aracaris are enjoying a meal

275
00:16:25,770 --> 00:16:28,803
when the toucan stops by.

276
00:16:36,365 --> 00:16:39,115
(dramatic music)

277
00:16:42,746 --> 00:16:45,860
Down on the jungle floors, struts the most stylish bird

278
00:16:45,860 --> 00:16:49,053
of Costa Rica, the great curassow.

279
00:16:51,380 --> 00:16:54,260
Standing up to 91 centimeters tall,

280
00:16:54,260 --> 00:16:58,160
these dapper crosses rock a Mohawk of curled feathers.

281
00:16:58,160 --> 00:17:01,310
They also have bright yellow bills and long tails

282
00:17:01,310 --> 00:17:03,810
to attract potential mates.

283
00:17:03,810 --> 00:17:07,180
Vulnerable, great curassows face increasing threats

284
00:17:07,180 --> 00:17:12,021
every day from deforestation and from being hunted for food.

285
00:17:12,021 --> 00:17:14,673
Their relatives, the crested guans,

286
00:17:14,673 --> 00:17:17,400
are usually found in the trees

287
00:17:17,400 --> 00:17:19,400
but this one stalks the jungle floor

288
00:17:19,400 --> 00:17:21,863
in search of fallen fruit and insects.

289
00:17:24,110 --> 00:17:26,620
Pale-billed woodpeckers are the largest of the eight

290
00:17:26,620 --> 00:17:29,170
woodpeckers found in the Osa Peninsula.

291
00:17:29,170 --> 00:17:31,170
And they can be found knocking into trees

292
00:17:31,170 --> 00:17:33,923
in search of the larvae of woodboring beetles.

293
00:17:34,776 --> 00:17:37,776
(crickets chirping)

294
00:17:38,790 --> 00:17:41,540
(dramatic music)

295
00:17:44,630 --> 00:17:48,390
Down by the shore, herons have to share their territory

296
00:17:48,390 --> 00:17:51,793
not only with kingfishers but with crocodiles.

297
00:17:53,242 --> 00:17:55,992
(dramatic music)

298
00:18:05,571 --> 00:18:08,160
The little blue heron spends its days stalking small fish

299
00:18:08,160 --> 00:18:10,173
and amphibians in the shallows.

300
00:18:13,550 --> 00:18:14,963
His patience pays off.

301
00:18:24,641 --> 00:18:27,300
(dramatic music)

302
00:18:27,300 --> 00:18:29,570
Kingfishers employ a similar strategy

303
00:18:29,570 --> 00:18:31,650
but instead of standing in the water,

304
00:18:31,650 --> 00:18:33,593
they have mastered the dive.

305
00:18:35,269 --> 00:18:37,840
This Amazon Kingfisher perches and waits.

306
00:18:37,840 --> 00:18:40,423
He sees a fish and dives.

307
00:18:41,660 --> 00:18:43,500
He takes into account the refraction

308
00:18:44,626 --> 00:18:47,513
of the light in the water and is successful.

309
00:18:49,910 --> 00:18:54,910
The fish struggles but a few smacks take care of that.

310
00:19:03,379 --> 00:19:06,129
(birds chirping)

311
00:19:09,333 --> 00:19:11,916
(upbeat music)

312
00:19:13,060 --> 00:19:16,102
(birds chirping)

313
00:19:16,102 --> 00:19:19,220
The jungles of Costa Rica are home to a variety of parrots.

314
00:19:19,220 --> 00:19:23,813
And perhaps the most talkative are the yellow-naped parrots.

315
00:19:24,974 --> 00:19:28,141
(wildlife chattering)

316
00:19:29,910 --> 00:19:32,040
These parrots are particularly famous

317
00:19:32,040 --> 00:19:34,360
for their amazing ability to talk

318
00:19:34,360 --> 00:19:36,083
and are often kept as pets.

319
00:19:36,966 --> 00:19:39,099
(parrot chirping)

320
00:19:39,099 --> 00:19:41,300
(speaking foreign language)

321
00:19:41,300 --> 00:19:45,089
As a result, they can make some pretty creepy sounds.

322
00:19:45,089 --> 00:19:47,756
(parrot cawing)

323
00:19:51,340 --> 00:19:55,097
Possibly the most beautiful bird in all of Central America

324
00:19:55,097 --> 00:19:58,330
is also one of its most elusive.

325
00:19:58,330 --> 00:20:00,980
The resplendent quetzal.

326
00:20:00,980 --> 00:20:04,950
These beautiful birds go to extremes during courtship.

327
00:20:04,950 --> 00:20:07,560
The male will grow gorgeous twin tail feathers

328
00:20:07,560 --> 00:20:10,159
that can be up to a meter long.

329
00:20:10,159 --> 00:20:13,686
Then he will hollow out a den in a rotten tree,

330
00:20:13,686 --> 00:20:17,420
keeping it as clean as possible for the hopes of attracting

331
00:20:17,420 --> 00:20:18,413
his chosen mate.

332
00:20:19,400 --> 00:20:22,263
Only time will tell if she agrees to his offer.

333
00:20:26,310 --> 00:20:29,060
(dramatic music)

334
00:20:32,335 --> 00:20:33,980
Rivaling the quetzal for its beauty

335
00:20:33,980 --> 00:20:35,973
are Costa Rica's hummingbirds.

336
00:20:38,920 --> 00:20:41,360
There are dozens of species of hummingbird

337
00:20:41,360 --> 00:20:45,210
found in Costa Rica and they come in a wide variety of sizes

338
00:20:45,210 --> 00:20:46,650
and colors.

339
00:20:46,650 --> 00:20:48,443
Many are even iridescent.

340
00:20:51,844 --> 00:20:53,760
(dramatic music)

341
00:20:53,760 --> 00:20:57,630
Hummingbirds can beat their wings up to 200 times a second

342
00:20:57,630 --> 00:21:00,180
and because of this, they can hover in place

343
00:21:00,180 --> 00:21:02,963
and they're the only bird that can fly backwards.

344
00:21:04,088 --> 00:21:05,230
(dramatic music)

345
00:21:05,230 --> 00:21:07,770
They are known as nectarivores as their diet

346
00:21:07,770 --> 00:21:10,990
is made up almost entirely of plant nectar.

347
00:21:10,990 --> 00:21:14,250
Their hovering allows them to easily collect this nectar,

348
00:21:14,250 --> 00:21:18,086
especially from flowers that are too small to support

349
00:21:18,086 --> 00:21:18,919
their body weight.

350
00:21:18,919 --> 00:21:21,280
Their extreme control of their body movement

351
00:21:21,280 --> 00:21:24,370
is also very helpful when avoiding other hummingbirds

352
00:21:24,370 --> 00:21:26,083
gathered at a single flower.

353
00:21:28,330 --> 00:21:32,093
It's estimated that hummingbirds visit 20 flowers a minute.

354
00:21:33,270 --> 00:21:36,770
In order to eat all of this nectar, they have super long

355
00:21:36,770 --> 00:21:38,620
split tongues which are about double

356
00:21:38,620 --> 00:21:39,993
the length of their bills.

357
00:21:43,190 --> 00:21:46,030
Hummingbirds feed every 10 to 15 minutes

358
00:21:46,030 --> 00:21:47,870
and in a day, they will consume

359
00:21:47,870 --> 00:21:49,743
half their body weight in sugar.

360
00:21:50,980 --> 00:21:54,350
Their hearts beat around 1,000 times per minute

361
00:21:54,350 --> 00:21:57,250
and due to their high metabolism, if a hummingbird

362
00:21:57,250 --> 00:22:00,713
went without food for a few hours, they would die.

363
00:22:02,310 --> 00:22:03,710
To make it through the night,

364
00:22:03,710 --> 00:22:07,390
they enter a hibernation-like state called torpor

365
00:22:07,390 --> 00:22:10,740
during which their metabolism is lowered significantly

366
00:22:10,740 --> 00:22:13,190
and they don't need as much energy to keep going.

367
00:22:16,410 --> 00:22:19,920
Further north, along the Pacific Coast of Costa Rica,

368
00:22:19,920 --> 00:22:23,700
lies a park filled with a whole host of wildlife.

369
00:22:23,700 --> 00:22:28,700
Sloths, monkeys, caiman, land crabs, and tourists.

370
00:22:32,240 --> 00:22:34,373
Manuel Antonio National Park.

371
00:22:38,200 --> 00:22:43,200
Home to 109 species of mammals, 184 species of birds,

372
00:22:44,130 --> 00:22:47,900
and some of the most pristine beaches in Central America,

373
00:22:47,900 --> 00:22:50,560
this National Park sees a lot of activity

374
00:22:50,560 --> 00:22:53,179
from both animals and tourists.

375
00:22:53,179 --> 00:22:55,929
(dramatic music)

376
00:22:57,000 --> 00:22:59,940
The stars of the park are the sloths.

377
00:22:59,940 --> 00:23:03,390
The three-toed sloth is the slow, grinning species

378
00:23:03,390 --> 00:23:07,128
that relies solely on vegetation to survive.

379
00:23:07,128 --> 00:23:09,878
Aha, there you are.

380
00:23:10,886 --> 00:23:11,719
(soft music)

381
00:23:11,719 --> 00:23:15,253
The three-toed sloth is the slowest mammal in the world.

382
00:23:21,060 --> 00:23:23,790
They spend so much of their lives not moving

383
00:23:23,790 --> 00:23:26,930
that algae grows on their coats.

384
00:23:26,930 --> 00:23:30,160
This tints their coat green, providing them with camouflage

385
00:23:30,160 --> 00:23:33,203
against the green tree canopy that they call home.

386
00:23:34,570 --> 00:23:37,606
There are many differences between two and three-toed sloths

387
00:23:37,606 --> 00:23:41,810
but as their name suggests, two-toed sloths have two claws

388
00:23:41,810 --> 00:23:45,123
on their forelimbs and three toes on their hind limbs.

389
00:23:46,680 --> 00:23:49,360
The two-toed sloth can be surprisingly agile

390
00:23:49,360 --> 00:23:51,880
and can zip around quickly if necessary,

391
00:23:51,880 --> 00:23:53,860
though they still spend most of their time

392
00:23:53,860 --> 00:23:55,463
just slothing around.

393
00:23:57,323 --> 00:23:58,336
(upbeat music)

394
00:23:58,336 --> 00:23:59,730
Though the three-toed sloth may smile more,

395
00:23:59,730 --> 00:24:01,720
they're both famous for constantly looking

396
00:24:01,720 --> 00:24:02,983
as high as a kite.

397
00:24:06,177 --> 00:24:09,099
♪ Chill out, stay cool, relax ♪

398
00:24:09,099 --> 00:24:11,054
♪ Let go ♪

399
00:24:11,054 --> 00:24:12,798
♪ Oh, let go, let go ♪

400
00:24:12,798 --> 00:24:15,425
♪ Chill out, stay cool, relax ♪

401
00:24:15,425 --> 00:24:17,508
♪ Let go ♪

402
00:24:19,421 --> 00:24:21,493
(soft music)

403
00:24:21,493 --> 00:24:24,410
Sloths have very long limbs, allowing them to easily

404
00:24:24,410 --> 00:24:26,993
grab tree trunks and branches while climbing.

405
00:24:28,275 --> 00:24:31,030
They use their incredibly long claws

406
00:24:31,030 --> 00:24:32,930
to dig into the bark while they climb.

407
00:24:37,830 --> 00:24:40,460
They are so good at hanging onto branches,

408
00:24:40,460 --> 00:24:42,540
often times when they die,

409
00:24:42,540 --> 00:24:44,763
they'll remain hanging from the trees.

410
00:24:46,060 --> 00:24:47,980
But it's not just their claws,

411
00:24:47,980 --> 00:24:51,510
sloths have highly specialized retractor muscles

412
00:24:51,510 --> 00:24:53,340
which allow them to hang onto trees

413
00:24:53,340 --> 00:24:56,393
at increasingly difficult positions with ease.

414
00:24:57,790 --> 00:25:00,500
Though they have very little muscle mass.

415
00:25:00,500 --> 00:25:03,923
About 30% less than what most mammals have.

416
00:25:05,280 --> 00:25:08,490
Sloths spend the majority of their lives in the trees

417
00:25:08,490 --> 00:25:12,400
and only really climb down when they need to poop

418
00:25:12,400 --> 00:25:15,853
which they strangely only have to do about once a week.

419
00:25:16,790 --> 00:25:19,700
On the ground, sloths lose any agility

420
00:25:19,700 --> 00:25:21,373
they had in the trees.

421
00:25:22,560 --> 00:25:25,770
In order to get around, they must pull themselves forward

422
00:25:25,770 --> 00:25:28,350
with their fore and hind limbs.

423
00:25:28,350 --> 00:25:30,810
None of their limbs can support their body weight

424
00:25:30,810 --> 00:25:34,200
and because of this they are classified as four armed

425
00:25:34,200 --> 00:25:36,293
rather than four-legged animals.

426
00:25:37,150 --> 00:25:39,470
Though in water, where they don't need to support

427
00:25:39,470 --> 00:25:42,373
their own weight, they are quite adept swimmers.

428
00:25:43,220 --> 00:25:45,863
It's just getting out that proves difficult.

429
00:25:47,990 --> 00:25:51,670
Sloths share the jungle with a whole host of other wildlife.

430
00:25:51,670 --> 00:25:53,920
Three species of monkey live here.

431
00:25:53,920 --> 00:25:56,470
The howler monkey occupies the upper canopy

432
00:25:56,470 --> 00:25:58,410
while the capuchin and squirrel monkeys

433
00:25:58,410 --> 00:26:00,054
live a little lower down.

434
00:26:00,054 --> 00:26:02,804
(dramatic music)

435
00:26:04,427 --> 00:26:05,676
Howler monkeys...

436
00:26:05,676 --> 00:26:08,426
(monkey howling)

437
00:26:11,720 --> 00:26:12,553
Howler...

438
00:26:12,553 --> 00:26:15,303
(monkey howling)

439
00:26:17,457 --> 00:26:18,969
Howl, howl, howler.

440
00:26:18,969 --> 00:26:20,591
(monkey howling)

441
00:26:20,591 --> 00:26:22,293
(groaning)

442
00:26:22,293 --> 00:26:23,871
(monkey howling)

443
00:26:23,871 --> 00:26:26,230
Howler monkeys sound like they're the ultimate terror

444
00:26:26,230 --> 00:26:29,003
in the jungle and that's the idea.

445
00:26:29,917 --> 00:26:33,180
(monkey howling)

446
00:26:33,180 --> 00:26:36,580
Yet, in reality, this is far from the case.

447
00:26:36,580 --> 00:26:39,410
While howler monkeys are the largest and surliest

448
00:26:39,410 --> 00:26:40,810
of the New World monkeys,

449
00:26:40,810 --> 00:26:44,310
they aren't particularly confrontational and their loud,

450
00:26:44,310 --> 00:26:46,340
scary call is meant as a warning

451
00:26:46,340 --> 00:26:48,839
to other monkeys to stay out.

452
00:26:48,839 --> 00:26:52,110
(monkey howling)

453
00:26:52,110 --> 00:26:56,170
Males are the loudest and have large specialized throats

454
00:26:56,170 --> 00:26:58,800
which contain a large hyoid bone.

455
00:26:58,800 --> 00:27:01,706
This helps boost their bark-like call.

456
00:27:01,706 --> 00:27:05,030
(monkey howling)

457
00:27:05,030 --> 00:27:07,510
Being constantly observed by tourists,

458
00:27:07,510 --> 00:27:09,980
howlers have developed an interesting strategy

459
00:27:09,980 --> 00:27:12,980
for keeping unwanted humans at bay.

460
00:27:12,980 --> 00:27:14,463
They pee on them.

461
00:27:15,570 --> 00:27:17,340
If you're near a howler monkey,

462
00:27:17,340 --> 00:27:20,216
it's probably best not to stand directly under them

463
00:27:20,216 --> 00:27:22,483
unless you don't mind getting wet.

464
00:27:25,390 --> 00:27:26,690
Oh, this one's got a baby.

465
00:27:30,290 --> 00:27:33,350
Capuchins have developed a special relationship with humans

466
00:27:33,350 --> 00:27:35,850
and have learned that tourists can be an excellent

467
00:27:36,753 --> 00:27:37,752
source of food.

468
00:27:37,752 --> 00:27:38,620
They have lost their fear of people

469
00:27:38,620 --> 00:27:40,740
and are often found raiding unsuspecting

470
00:27:40,740 --> 00:27:42,790
beach goers bags for food.

471
00:27:42,790 --> 00:27:45,770
This can be harmful for monkeys because processed foods

472
00:27:45,770 --> 00:27:49,284
can be either toxic or indigestible for them.

473
00:27:49,284 --> 00:27:50,400
(funky music)

474
00:27:50,400 --> 00:27:53,080
When there aren't any tourists around to feed them,

475
00:27:53,080 --> 00:27:55,543
capuchins are excellent foragers.

476
00:27:57,310 --> 00:27:59,590
Unlike many other New World monkeys,

477
00:27:59,590 --> 00:28:02,100
capuchins spend a lot of time on the ground

478
00:28:02,100 --> 00:28:05,740
looking for food and they're quite resourceful.

479
00:28:05,740 --> 00:28:08,560
They'll strip bark, they'll use sticks as tools,

480
00:28:08,560 --> 00:28:12,470
and they'll even use rocks to break open hard fruit.

481
00:28:12,470 --> 00:28:14,580
They even have a few tricks up their sleeves

482
00:28:14,580 --> 00:28:15,823
for finding water.

483
00:28:19,520 --> 00:28:21,880
Capuchins are considered to be one of the smartest

484
00:28:21,880 --> 00:28:24,160
New World monkeys and they've learned to rub

485
00:28:24,160 --> 00:28:27,210
different plants on themselves to keep ticks at bay

486
00:28:27,210 --> 00:28:30,143
and possibly even to treat inflammation.

487
00:28:32,040 --> 00:28:34,810
White-headed capuchins live in large troops.

488
00:28:34,810 --> 00:28:38,330
A big part of coming-of-age for juvenilis is playing,

489
00:28:38,330 --> 00:28:43,168
chasing, and wrestling and oh do they play.

490
00:28:43,168 --> 00:28:46,418
(upbeat playful music)

491
00:29:29,875 --> 00:29:32,840
At Manuel Antonio National Park, a lot of that play

492
00:29:32,840 --> 00:29:35,320
involves stealing things from tourists

493
00:29:35,320 --> 00:29:38,033
and then chasing each other for the stolen goods.

494
00:29:44,030 --> 00:29:47,603
Of course they tell us not to bring chips in for a reason.

495
00:29:48,751 --> 00:29:51,501
(dramatic music)

496
00:29:55,900 --> 00:29:58,150
Other animals have learned to do the same.

497
00:29:58,150 --> 00:30:00,970
coatis and raccoons have become very bold

498
00:30:00,970 --> 00:30:04,713
and can be seen patrolling the beaches in search of snacks.

499
00:30:04,713 --> 00:30:07,463
(dramatic music)

500
00:30:10,505 --> 00:30:12,922
(chattering)

501
00:30:20,898 --> 00:30:23,648
(dramatic music)

502
00:30:33,161 --> 00:30:36,210
These raids really show the limits of our bonds

503
00:30:36,210 --> 00:30:38,780
with our fellow man 'cause instead of stopping

504
00:30:38,780 --> 00:30:41,270
any of these animals, people tend to prefer

505
00:30:41,270 --> 00:30:43,950
getting cute pictures for Instagram.

506
00:30:43,950 --> 00:30:45,833
I mean, it makes sense.

507
00:30:47,252 --> 00:30:48,085
(soft music)

508
00:30:48,085 --> 00:30:51,520
Costa Rica is home to thousands of different species,

509
00:30:51,520 --> 00:30:54,660
many of which are endangered.

510
00:30:54,660 --> 00:30:58,360
Despite the surge of deforestation in Central America,

511
00:30:58,360 --> 00:31:01,560
over the past 20 years, Costa Rica has actually seen

512
00:31:01,560 --> 00:31:04,393
an increase in forest cover across the country.

513
00:31:05,550 --> 00:31:08,650
The country has set aside 25% of their land

514
00:31:08,650 --> 00:31:11,950
as Wildlife Sanctuaries and National Parks.

515
00:31:11,950 --> 00:31:15,030
Costa Ricans are very proud of their wildlife

516
00:31:15,030 --> 00:31:17,770
and go to great efforts to conserve it.

517
00:31:17,770 --> 00:31:21,330
Conservation centers like Alturas Wildlife Sanctuary

518
00:31:21,330 --> 00:31:24,094
and La Paz Waterfall Gardens take in injured wildlife

519
00:31:24,094 --> 00:31:27,593
and animals rescued from the Exotic Pet Trade.

520
00:31:29,221 --> 00:31:30,221
Hi, sweetie.

521
00:31:32,372 --> 00:31:33,640
(chuckling)

522
00:31:33,640 --> 00:31:35,403
This is maximum sloth effort.

523
00:31:36,260 --> 00:31:38,340
Their goal is to eventually release them

524
00:31:38,340 --> 00:31:41,670
back into the wild but some animals are too injured

525
00:31:41,670 --> 00:31:44,628
or too use to humans to ever return.

526
00:31:44,628 --> 00:31:45,860
(soft music)

527
00:31:45,860 --> 00:31:48,729
Costa Rica remains a bastion for wildlife,

528
00:31:48,729 --> 00:31:52,620
providing hope for the future of these endangered species

529
00:31:52,620 --> 00:31:55,280
and an inspiration to the rest of us

530
00:31:55,280 --> 00:31:58,901
showing that coexisting with nature is possible.

531
00:31:58,901 --> 00:32:02,068
(inspirational music)
