1
00:00:01,201 --> 00:00:04,169
(birds chirping)

2
00:00:04,205 --> 00:00:07,106
(bird squawking)

3
00:00:07,141 --> 00:00:08,107
(frog croaking)

4
00:00:08,142 --> 00:00:11,043
(animals cackling)

5
00:00:11,979 --> 00:00:14,346
(gorilla grumbling)

6
00:00:14,382 --> 00:00:17,516
- [Narrator] A female
western lowland gorilla.

7
00:00:18,719 --> 00:00:19,785
(gorilla grumbling)

8
00:00:19,820 --> 00:00:23,055
(gentle music)

9
00:00:23,090 --> 00:00:24,623
And her newborn.

10
00:00:25,559 --> 00:00:28,127
(gentle music)

11
00:00:30,731 --> 00:00:32,531
Just moments old.

12
00:00:32,566 --> 00:00:35,701
(gentle music)

13
00:00:35,736 --> 00:00:38,404
(flies buzzing)

14
00:00:42,743 --> 00:00:46,278
For his mother, the
arrival of her young baby

15
00:00:46,313 --> 00:00:49,882
is the start of a new
chapter in her adult life.

16
00:00:50,885 --> 00:00:54,319
(gentle music continues)

17
00:00:57,291 --> 00:00:58,123
Parenthood.

18
00:01:00,327 --> 00:01:02,895
(gentle music)

19
00:01:10,271 --> 00:01:12,538
Her journey will be challenging,

20
00:01:17,411 --> 00:01:18,744
full of excitement,

21
00:01:21,215 --> 00:01:22,214
uncertainty,

22
00:01:23,084 --> 00:01:25,484
and complete commitment.

23
00:01:25,519 --> 00:01:28,921
(gentle music continues)

24
00:01:30,024 --> 00:01:31,090
(gentle music)

25
00:01:31,125 --> 00:01:33,158
There will be mistakes.

26
00:01:33,194 --> 00:01:34,460
There always are.

27
00:01:41,702 --> 00:01:43,402
But success for her,

28
00:01:43,437 --> 00:01:46,138
and indeed for all parents,

29
00:01:46,173 --> 00:01:49,775
has perhaps the greatest of
consequences.

30
00:01:49,810 --> 00:01:53,846
(gentle music continues)

31
00:01:53,881 --> 00:01:57,583
It ensures the future
of life on our planet.

32
00:02:01,889 --> 00:02:04,957
(lighthearted music)

33
00:02:22,376 --> 00:02:25,110
(majestic music)

34
00:02:30,651 --> 00:02:32,784
(birds chirping)

35
00:02:32,820 --> 00:02:35,888
(lighthearted music)

36
00:02:37,791 --> 00:02:41,160
Parenthood is a journey like no
other.

37
00:02:43,063 --> 00:02:46,131
(lighthearted music)

38
00:02:49,170 --> 00:02:52,504
The responsibility of
providing constant food

39
00:02:52,540 --> 00:02:54,806
and safety for offspring

40
00:02:54,842 --> 00:02:57,209
can be extremely challenging.

41
00:03:06,520 --> 00:03:10,322
For most, it all begins with a
good home.

42
00:03:13,060 --> 00:03:16,128
(lighthearted music)

43
00:03:16,163 --> 00:03:17,596
A mother lion

44
00:03:17,631 --> 00:03:21,333
in the grasslands of the
Kalahari in Botswana.

45
00:03:31,512 --> 00:03:35,847
Her 20-strong pride is ruled
by her and her sisters,

46
00:03:38,252 --> 00:03:40,819
who each has her own cubs.

47
00:03:43,224 --> 00:03:45,023
One mighty family

48
00:03:45,059 --> 00:03:47,593
who help each other
through thick and thin.

49
00:03:47,628 --> 00:03:48,827
(lighthearted music continues)

50
00:03:48,862 --> 00:03:51,363
(cub whining)

51
00:03:54,435 --> 00:03:59,538
For months, their home is
scorched by 45-degree heat.

52
00:03:59,573 --> 00:04:02,507
(thunder rumbling)

53
00:04:04,545 --> 00:04:08,180
(thunder cracking)

54
00:04:08,215 --> 00:04:12,417
But once a year, their
territory is brought to life

55
00:04:12,453 --> 00:04:14,486
by distant rains.

56
00:04:16,423 --> 00:04:17,723
(lighthearted music)

57
00:04:17,758 --> 00:04:20,692
(elephant roaring)

58
00:04:26,934 --> 00:04:29,301
(elephant grumbling)

59
00:04:29,336 --> 00:04:31,937
Up until now, these cubs

60
00:04:31,972 --> 00:04:34,506
have had very little experience
of water.

61
00:04:37,111 --> 00:04:38,577
(water splashing)

62
00:04:38,612 --> 00:04:40,879
So their mother will have to
guide them

63
00:04:40,914 --> 00:04:42,948
to get them through the
(indistinct).

64
00:04:42,983 --> 00:04:46,318
(lion snarling)

65
00:04:46,353 --> 00:04:47,619
(lion snarling)

66
00:04:47,655 --> 00:04:50,155
(cub whining)

67
00:04:51,158 --> 00:04:54,493
(lion grumbling) (water
splashing)

68
00:04:54,528 --> 00:04:56,662
(lion snarling)

69
00:04:56,697 --> 00:04:57,496
(cub squawking)

70
00:04:57,531 --> 00:05:00,365
(water splashing)

71
00:05:02,136 --> 00:05:02,968
(lighthearted music)

72
00:05:03,003 --> 00:05:05,837
(water splashing)

73
00:05:07,908 --> 00:05:10,175
Getting used to swamp living

74
00:05:10,210 --> 00:05:12,611
is a vital part of their cubs'
upbringing.

75
00:05:15,416 --> 00:05:17,916
Because these precious waters

76
00:05:17,951 --> 00:05:20,819
attract animals from miles
around.

77
00:05:22,289 --> 00:05:25,457
(buffaloes grumbling)

78
00:05:26,994 --> 00:05:28,126
Cape Buffalo.

79
00:05:30,197 --> 00:05:32,564
The smell of fresh water lures
them

80
00:05:32,599 --> 00:05:34,633
from the surrounding savanna.

81
00:05:34,668 --> 00:05:36,034
(rhythmic music)

82
00:05:36,070 --> 00:05:38,904
And they come in extraordinary
numbers.

83
00:05:39,873 --> 00:05:44,876
(intrepid music) (buffaloes
grumbling)

84
00:05:48,716 --> 00:05:51,149
A herd three miles long

85
00:05:51,185 --> 00:05:53,652
and full of one-ton animals.

86
00:05:58,559 --> 00:06:00,826
(singers singing in foreign
language)

87
00:06:00,861 --> 00:06:03,362
(rhythmic music)

88
00:06:03,397 --> 00:06:04,363
(singers singing in foreign
language)

89
00:06:04,398 --> 00:06:07,666
- They too cannot
survive without the water

90
00:06:07,701 --> 00:06:10,001
at the centre of the lion's
territory.

91
00:06:11,271 --> 00:06:14,439
(buffaloes grumbling)

92
00:06:15,542 --> 00:06:20,345
She must show her cubs that
patience is their greatest ally.

93
00:06:20,381 --> 00:06:24,616
(singers singing in foreign
language)

94
00:06:24,651 --> 00:06:25,984
(buffaloes grumbling)

95
00:06:26,019 --> 00:06:27,786
Once in the swamp,

96
00:06:27,821 --> 00:06:31,256
the buffaloes spread
out into smaller groups.

97
00:06:31,291 --> 00:06:33,492
(intrepid music)

98
00:06:33,527 --> 00:06:35,160
(singers singing in foreign
language)

99
00:06:35,195 --> 00:06:39,264
Lionesses will take the lead in
any hunt.

100
00:06:39,299 --> 00:06:42,401
(apprehensive music)

101
00:06:43,704 --> 00:06:46,772
But a mother here has the added
pressure

102
00:06:46,807 --> 00:06:50,809
of having to teach her growing
cubs how to tackle giants.

103
00:06:52,079 --> 00:06:55,747
(apprehensive music)

104
00:06:55,783 --> 00:06:58,984
(water splashing)

105
00:06:59,019 --> 00:06:59,885
(buffalo huffing)

106
00:06:59,920 --> 00:07:01,787
(buffalo grumbling)

107
00:07:01,822 --> 00:07:04,656
(buffalo huffing)

108
00:07:06,059 --> 00:07:09,828
One swipe of its horns
could kill any one of them.

109
00:07:10,831 --> 00:07:14,366
(buffalo grumbling)

110
00:07:14,401 --> 00:07:16,968
The cubs must watch and learn.

111
00:07:17,838 --> 00:07:20,372
(buffalo grumbling)

112
00:07:20,407 --> 00:07:21,740
(buffalo huffing)

113
00:07:21,775 --> 00:07:24,042
(buffalo grumbling)

114
00:07:24,077 --> 00:07:26,044
(buffalo huffing)

115
00:07:26,079 --> 00:07:28,680
(buffalo grumbling)

116
00:07:28,715 --> 00:07:30,882
(apprehensive music)

117
00:07:30,918 --> 00:07:32,951
(singer singing in foreign
language)

118
00:07:32,986 --> 00:07:35,620
(buffalo groaning)

119
00:07:35,656 --> 00:07:37,856
(buffalo grumbling)

120
00:07:37,891 --> 00:07:38,957
(suspenseful music)

121
00:07:38,992 --> 00:07:39,891
(buffalo grumbling)

122
00:07:39,927 --> 00:07:41,493
(water splashing)

123
00:07:41,528 --> 00:07:45,130
(buffalo grumbling)

124
00:07:45,165 --> 00:07:48,300
(buffalo groaning)

125
00:07:48,335 --> 00:07:50,368
(buffalo huffing)

126
00:07:50,404 --> 00:07:54,105
(buffalo groaning)

127
00:07:54,141 --> 00:07:57,042
(buffalo groaning)

128
00:08:00,681 --> 00:08:05,684
(lion snarling)
(buffalo groaning)

129
00:08:06,987 --> 00:08:11,990
The younger lions are allowed
to be the first to feast.

130
00:08:12,326 --> 00:08:15,727
(buffalo groaning) (flies
buzzing)

131
00:08:15,762 --> 00:08:19,631
Hunting giants, however,
is not without its risks.

132
00:08:21,802 --> 00:08:24,836
One of the pride's mothers is
missing.

133
00:08:26,373 --> 00:08:28,807
(lion whining)

134
00:08:28,842 --> 00:08:31,376
Contact calls go unanswered.

135
00:08:32,513 --> 00:08:35,213
(lion grumbling)

136
00:08:35,249 --> 00:08:38,083
(lions grumbling)

137
00:08:42,923 --> 00:08:45,824
(melancholy music)

138
00:08:47,794 --> 00:08:50,529
(lion grumbling)

139
00:08:51,765 --> 00:08:54,933
In attempting to provide
food for her young,

140
00:08:54,968 --> 00:08:57,502
she has been gored by a buffalo.

141
00:09:01,275 --> 00:09:04,509
There is nothing the pride can
do to help.

142
00:09:06,713 --> 00:09:07,512
(lion grumbling)

143
00:09:07,548 --> 00:09:08,680
(melancholy music continues)

144
00:09:08,715 --> 00:09:11,316
(lion huffing)

145
00:09:14,922 --> 00:09:18,189
With her cubs too young
to hunt for themselves,

146
00:09:18,225 --> 00:09:22,294
her death leaves their future
uncertain.

147
00:09:22,329 --> 00:09:24,829
(cub whining)

148
00:09:32,973 --> 00:09:35,540
(lion huffing)

149
00:09:36,843 --> 00:09:37,642
(melancholy music continues)

150
00:09:37,678 --> 00:09:38,577
(cub whining)

151
00:09:38,612 --> 00:09:40,979
But they don't have to face it
alone.

152
00:09:42,115 --> 00:09:44,950
(uplifting music)

153
00:09:53,727 --> 00:09:56,861
The matriarchs will take
on responsibility for them.

154
00:10:06,373 --> 00:10:09,140
(lion grumbling)

155
00:10:10,043 --> 00:10:15,046
In lion society, females often
share the load of parenting.

156
00:10:15,849 --> 00:10:18,016
(uplifting music continues)

157
00:10:18,051 --> 00:10:21,519
Related adults will continue
to care for the orphans

158
00:10:21,555 --> 00:10:23,722
alongside their own offspring.

159
00:10:25,726 --> 00:10:29,060
It'll be another year before
they're fully independent.

160
00:10:31,932 --> 00:10:32,998
(cubs squealing)

161
00:10:33,033 --> 00:10:34,232
(lion grumbling)

162
00:10:34,267 --> 00:10:37,769
In that time, they must be
taught how to survive here.

163
00:10:39,072 --> 00:10:39,871
(lion snarling)

164
00:10:39,906 --> 00:10:43,808
(uplifting music continues)

165
00:10:43,844 --> 00:10:47,145
And luckily for them,
the leader of this pride

166
00:10:47,180 --> 00:10:49,047
is an excellent teacher.

167
00:10:50,484 --> 00:10:53,485
(suspenseful music)

168
00:11:02,896 --> 00:11:05,563
(lion growling)

169
00:11:06,433 --> 00:11:09,734
(bird squawking)

170
00:11:09,770 --> 00:11:12,837
(lighthearted music)

171
00:11:13,907 --> 00:11:18,910
Parental investment is a risky
strategy for many animals,

172
00:11:21,448 --> 00:11:25,917
particularly in the
largest of all habitats,

173
00:11:25,952 --> 00:11:26,785
the ocean.

174
00:11:32,125 --> 00:11:36,461
The sheer diversity of life
makes some parts of the ocean

175
00:11:36,496 --> 00:11:39,230
a highly competitive
environment.

176
00:11:39,266 --> 00:11:42,100
(lighthearted music continues)

177
00:11:42,135 --> 00:11:45,637
So the animals who choose to
raise their offspring here

178
00:11:45,672 --> 00:11:47,739
need to have an edge.

179
00:11:50,444 --> 00:11:53,511
(lighthearted music)

180
00:11:55,749 --> 00:11:59,350
Here in Indonesia, protected by
the reef,

181
00:11:59,386 --> 00:12:03,121
lives one of the ocean's
most ingenious parents,

182
00:12:05,792 --> 00:12:08,359
a female boxer crab.

183
00:12:08,395 --> 00:12:10,662
(lighthearted music continues)

184
00:12:10,697 --> 00:12:12,497
Attached to her underside

185
00:12:12,532 --> 00:12:15,700
is her brood of over a thousand
eggs.

186
00:12:17,370 --> 00:12:20,972
Her challenge is to keep
them safe until they hatch

187
00:12:22,109 --> 00:12:24,609
whilst keeping herself well fed.

188
00:12:27,080 --> 00:12:29,047
So like any good parent,

189
00:12:29,082 --> 00:12:31,549
she's come prepared with a
solution.

190
00:12:32,619 --> 00:12:36,788
(lighthearted music continues)

191
00:12:36,823 --> 00:12:39,491
On her claws are live anemones

192
00:12:39,526 --> 00:12:42,160
that she's collected
from the reef around her.

193
00:12:46,266 --> 00:12:49,534
The anemones filter food
from the surrounding water,

194
00:12:50,837 --> 00:12:53,872
which the crab mother steals for
herself.

195
00:12:56,777 --> 00:12:59,811
It's an ingenious way to keep
energised

196
00:12:59,846 --> 00:13:01,312
while looking after young.

197
00:13:06,353 --> 00:13:08,553
But it's not without risk.

198
00:13:11,258 --> 00:13:12,290
(apprehensive music)

199
00:13:12,325 --> 00:13:14,626
To capture the food she needs,

200
00:13:14,661 --> 00:13:17,328
she must take her
anemones out in the open.

201
00:13:19,199 --> 00:13:22,300
(apprehensive music)

202
00:13:23,570 --> 00:13:24,502
A cuttlefish,

203
00:13:26,640 --> 00:13:30,642
a cunning predator that
pounces on the unprepared.

204
00:13:30,677 --> 00:13:33,678
(suspenseful music)

205
00:13:37,818 --> 00:13:40,819
(suspenseful music)

206
00:13:42,122 --> 00:13:44,088
Exposed and alone,

207
00:13:48,728 --> 00:13:51,029
she is a sitting crab.

208
00:13:52,365 --> 00:13:55,366
(suspenseful music)

209
00:14:00,140 --> 00:14:02,140
But she isn't defenceless.

210
00:14:05,212 --> 00:14:07,745
Her anemones have venomous
stings

211
00:14:07,781 --> 00:14:10,181
that can deter most predators,

212
00:14:12,319 --> 00:14:15,920
a very effective weapon for a
mother in need of protection.

213
00:14:17,190 --> 00:14:20,291
(apprehensive music)

214
00:14:22,996 --> 00:14:26,030
In fact, her anemones are such
good tools

215
00:14:27,534 --> 00:14:31,269
that they are highly prized
amongst the crab community.

216
00:14:31,304 --> 00:14:34,405
(lighthearted music)

217
00:14:42,082 --> 00:14:45,683
And this mother has a jealous
rival.

218
00:14:47,821 --> 00:14:51,189
(apprehensive music)

219
00:14:51,224 --> 00:14:55,059
(lighthearted music)

220
00:14:55,095 --> 00:14:58,396
Empty clawed, her
opponent will do anything

221
00:14:58,431 --> 00:15:00,865
to secure her own anemone.

222
00:15:00,901 --> 00:15:02,767
(apprehensive music)

223
00:15:02,802 --> 00:15:05,803
(suspenseful music)

224
00:15:11,077 --> 00:15:14,178
She isn't going to surrender
them without a fight.

225
00:15:15,081 --> 00:15:18,082
(suspenseful music)

226
00:15:28,561 --> 00:15:33,264
Overpowered, the mother
loses one of her anemones.

227
00:15:35,969 --> 00:15:39,370
The battle leaves her
exhausted and vulnerable.

228
00:15:41,274 --> 00:15:45,076
She needs to lie low and
buy herself some time.

229
00:15:47,414 --> 00:15:49,113
(gentle music)

230
00:15:49,149 --> 00:15:52,917
Because this supermom
has yet another trick.

231
00:15:55,989 --> 00:16:00,992
Slowly and meticulously, she
dissects her remaining anemone,

232
00:16:03,063 --> 00:16:05,263
creating a clone.

233
00:16:10,403 --> 00:16:11,469
(gentle music)

234
00:16:11,504 --> 00:16:14,138
Her remarkable problem solving

235
00:16:14,174 --> 00:16:17,475
allows her to keep herself
and her young alive

236
00:16:17,510 --> 00:16:19,110
for a few more days,

237
00:16:21,114 --> 00:16:24,482
until eventually she's
ready to let them go.

238
00:16:35,428 --> 00:16:38,029
(gentle music)

239
00:16:39,332 --> 00:16:42,033
climbing to the top of her coral
home,

240
00:16:42,068 --> 00:16:46,404
she begins to release her tiny
offspring into the current,

241
00:16:50,977 --> 00:16:52,677
a few at a time,

242
00:16:55,415 --> 00:16:59,784
until all her crablets are
independent.

243
00:17:03,490 --> 00:17:06,090
Thanks to her care and
attention,

244
00:17:06,126 --> 00:17:09,594
she has given them an
excellent start in life.

245
00:17:17,203 --> 00:17:19,937
(birds chirping)

246
00:17:23,543 --> 00:17:27,645
Raising offspring alone
is extremely challenging,

247
00:17:29,315 --> 00:17:32,717
so many parents resort to
teamwork.

248
00:17:32,752 --> 00:17:35,853
(lighthearted music)

249
00:17:38,625 --> 00:17:42,026
A female burrowing owl
is looking for a partner

250
00:17:42,062 --> 00:17:44,796
amongst the wild lands of
Arizona.

251
00:17:48,401 --> 00:17:51,602
And this young male seems eager
to please.

252
00:17:55,642 --> 00:17:57,208
(lighthearted music)

253
00:17:57,243 --> 00:18:00,745
To win her over, he must
first find a decent burrow.

254
00:18:01,648 --> 00:18:03,948
And that is proving tricky.

255
00:18:06,352 --> 00:18:10,088
Burrowing owls use holes
abandoned by other animals.

256
00:18:11,891 --> 00:18:15,293
But the ones he's found
are either still in use

257
00:18:18,631 --> 00:18:21,732
or already have well-established
families.

258
00:18:21,768 --> 00:18:25,703
(lighthearted music continues)

259
00:18:28,808 --> 00:18:31,075
Her patience is running thin.

260
00:18:34,481 --> 00:18:37,148
(birds chirping)

261
00:18:37,183 --> 00:18:40,351
When finally he's found one,

262
00:18:40,386 --> 00:18:44,288
she flies in for a closer
inspection.

263
00:18:44,324 --> 00:18:47,391
(lighthearted music)

264
00:18:50,897 --> 00:18:53,965
(lighthearted music)

265
00:18:56,769 --> 00:18:59,437
(soil rustling)

266
00:19:01,541 --> 00:19:04,775
The hallway clearly requires
a little housekeeping.

267
00:19:08,615 --> 00:19:12,116
Though small inside, it's
deep enough underground

268
00:19:12,152 --> 00:19:15,153
to keep her chicks cool
in the midday heat.

269
00:19:16,689 --> 00:19:17,488
(lighthearted music)

270
00:19:17,524 --> 00:19:19,724
Returning to await her verdict,

271
00:19:24,864 --> 00:19:28,599
he receives a less than
enthusiastic yes.

272
00:19:38,278 --> 00:19:42,013
Over the coming weeks,
she will lay one egg a day

273
00:19:42,048 --> 00:19:45,249
and then incubate them
all until they hatch.

274
00:19:47,387 --> 00:19:48,519
(lighthearted music)

275
00:19:48,555 --> 00:19:50,555
His responsibility now

276
00:19:50,590 --> 00:19:53,891
is to provide her with a
constant supply of food,

277
00:20:01,768 --> 00:20:05,203
until eventually their teamwork
pays off.

278
00:20:07,840 --> 00:20:10,241
(lighthearted music)

279
00:20:10,276 --> 00:20:13,277
(chick chirping)

280
00:20:13,313 --> 00:20:15,780
(chick chirping)

281
00:20:15,815 --> 00:20:18,049
(chicks chirping)

282
00:20:18,084 --> 00:20:20,918
(chicks chirping)

283
00:20:22,055 --> 00:20:25,523
At first, the father's
food supplies are enough

284
00:20:25,558 --> 00:20:27,658
to keep their chicks growing.

285
00:20:27,694 --> 00:20:30,061
(chicks chirping)

286
00:20:30,096 --> 00:20:33,364
But soon, both parents will have
to work

287
00:20:33,399 --> 00:20:35,800
to put enough food on the table.

288
00:20:35,835 --> 00:20:38,769
(owl squawking)

289
00:20:38,805 --> 00:20:41,906
(lighthearted music)

290
00:20:52,318 --> 00:20:53,117
(chick chirping)

291
00:20:53,152 --> 00:20:56,220
(lighthearted music)

292
00:21:01,661 --> 00:21:04,428
(chick chirping)

293
00:21:07,000 --> 00:21:11,469
All this constant activity
inevitably attracts attention.

294
00:21:12,405 --> 00:21:15,473
(apprehensive music)

295
00:21:20,713 --> 00:21:21,512
(apprehensive music)

296
00:21:21,547 --> 00:21:23,981
(roadrunner cooing)

297
00:21:24,017 --> 00:21:25,316
A roadrunner.

298
00:21:25,351 --> 00:21:26,350
(roadrunner cooing)

299
00:21:26,386 --> 00:21:30,054
Fast and wily, this opportunist
could kill

300
00:21:30,089 --> 00:21:32,657
an entire brood of young chicks.

301
00:21:32,692 --> 00:21:35,793
(apprehensive music)

302
00:21:38,598 --> 00:21:40,398
Their burrow has been chosen

303
00:21:40,433 --> 00:21:42,767
to keep them hidden from
predators.

304
00:21:42,802 --> 00:21:44,568
(apprehensive music)

305
00:21:44,604 --> 00:21:46,971
But at the first sign of danger,

306
00:21:47,006 --> 00:21:49,340
the chicks create a deterrent.

307
00:21:50,276 --> 00:21:53,010
(chicks hissing)

308
00:21:54,814 --> 00:21:59,417
Their call mimics the sound
of an angry rattlesnake.

309
00:21:59,452 --> 00:22:02,953
(chicks hissing)

310
00:22:02,989 --> 00:22:07,191
But rattlesnakes are one of the
roadrunner's favourite prey.

311
00:22:07,226 --> 00:22:09,493
(apprehensive music)

312
00:22:09,529 --> 00:22:11,162
Returning with takeaway,

313
00:22:12,365 --> 00:22:15,199
the father is alerted to the
danger.

314
00:22:15,234 --> 00:22:18,302
(apprehensive music)

315
00:22:20,640 --> 00:22:23,641
(suspenseful music)

316
00:22:25,011 --> 00:22:27,678
(owl squawking)

317
00:22:28,781 --> 00:22:31,082
Disaster averted.

318
00:22:31,117 --> 00:22:32,783
(roadrunner cooing)

319
00:22:32,819 --> 00:22:35,486
(owl squawking)

320
00:22:37,056 --> 00:22:38,622
(roadrunner cooing)

321
00:22:38,658 --> 00:22:39,690
(owl chirping) (lighthearted
music)

322
00:22:39,726 --> 00:22:42,159
But now, both parents are caught

323
00:22:42,195 --> 00:22:45,463
between keeping a watchful
eye on their chicks

324
00:22:45,498 --> 00:22:48,733
and providing enough food
for them to grow large enough

325
00:22:48,768 --> 00:22:50,234
to defend themselves.

326
00:22:50,269 --> 00:22:53,337
(lighthearted music)

327
00:22:56,709 --> 00:22:58,476
(chicks squawking)

328
00:22:58,511 --> 00:23:00,611
They work around the clock.

329
00:23:01,514 --> 00:23:04,448
(chicks squawking)

330
00:23:07,820 --> 00:23:12,390
And their chicks' expectations
are seemingly never ending.

331
00:23:12,425 --> 00:23:15,126
(chicks chirping)

332
00:23:15,161 --> 00:23:18,662
The parents' lives soon
reach a turning point.

333
00:23:20,633 --> 00:23:21,766
(chick squawking)

334
00:23:21,801 --> 00:23:24,535
The growing chicks begin
spending more and more time

335
00:23:24,570 --> 00:23:26,570
exploring their surroundings.

336
00:23:26,606 --> 00:23:30,541
(lighthearted music continues)

337
00:23:30,576 --> 00:23:33,110
And there are less demands on
the parents

338
00:23:33,146 --> 00:23:35,646
as a few of the chicks become
capable

339
00:23:35,681 --> 00:23:37,681
of finding their own snacks.

340
00:23:45,391 --> 00:23:47,658
(chick squawking)

341
00:23:47,693 --> 00:23:51,829
For the parents, that is a
welcome relief.

342
00:23:52,799 --> 00:23:55,633
(chick squawking)

343
00:24:01,908 --> 00:24:03,507
(chick squawking)

344
00:24:03,543 --> 00:24:05,843
(lighthearted music)

345
00:24:05,878 --> 00:24:08,979
Pa

346
00:24:09,015 --> 00:24:11,882
Parenthood is even harder

347
00:24:11,918 --> 00:24:14,452
when the environment
is working against you.

348
00:24:17,824 --> 00:24:20,791
And for those parents who
need reliable fresh water

349
00:24:20,827 --> 00:24:24,528
to raise their young, the
conditions are rarely perfect.

350
00:24:28,100 --> 00:24:31,302
(birds squeaking)

351
00:24:31,337 --> 00:24:34,071
The Ruaha River in Tanzania.

352
00:24:35,107 --> 00:24:37,808
For most of the year,
it provides a lifeline

353
00:24:37,844 --> 00:24:39,043
to those that live here.

354
00:24:41,180 --> 00:24:46,183
But during the dry season,
this refuge almost disappears,

355
00:24:51,424 --> 00:24:55,926
leaving this mother hippo
and her calf with a dilemma.

356
00:24:55,962 --> 00:24:58,395
(hippos huffing) (hippos
grumbling)

357
00:24:58,431 --> 00:25:01,265
(water splashing)

358
00:25:03,169 --> 00:25:04,969
(water sloshing)

359
00:25:05,004 --> 00:25:07,371
He was born just two months ago,

360
00:25:07,406 --> 00:25:09,940
at a time when water was
plentiful.

361
00:25:09,976 --> 00:25:11,642
(hippos grumbling)

362
00:25:11,677 --> 00:25:12,943
(hippo huffing)

363
00:25:12,979 --> 00:25:16,013
But now, there are only a few
pools left

364
00:25:16,048 --> 00:25:18,482
where the water is still deep
enough

365
00:25:18,518 --> 00:25:21,018
to shield him from the harsh
sun.

366
00:25:21,053 --> 00:25:23,954
(hippos grumbling)

367
00:25:25,091 --> 00:25:29,093
The other hippos in the
area have had the same idea.

368
00:25:29,128 --> 00:25:32,196
So her newfound nursery has
become

369
00:25:33,599 --> 00:25:35,699
a little crappy.

370
00:25:35,735 --> 00:25:38,669
(lighthearted music) (water
splashing)

371
00:25:38,704 --> 00:25:40,638
(hippos grumbling)

372
00:25:40,673 --> 00:25:45,676
(water splashing)
(hippos grumbling)

373
00:25:49,916 --> 00:25:52,550
(water splashing)

374
00:25:52,585 --> 00:25:55,419
(water splashing)

375
00:26:01,928 --> 00:26:04,194
(water splashing)

376
00:26:04,230 --> 00:26:05,496
(water splashing)

377
00:26:05,531 --> 00:26:06,597
For now though,

378
00:26:06,632 --> 00:26:09,400
hygiene is the least of
the mother's worries.

379
00:26:09,435 --> 00:26:11,068
(hippos grumbling) (hippos
huffing)

380
00:26:11,103 --> 00:26:14,004
These enormous fountains of
fertiliser

381
00:26:14,040 --> 00:26:18,108
require 50 kilos of vegetation
every day.

382
00:26:18,144 --> 00:26:20,010
(hippos grumbling) (hippos
huffing)

383
00:26:20,046 --> 00:26:22,880
And now, in the dry season,

384
00:26:22,915 --> 00:26:24,815
that is a problem.

385
00:26:24,850 --> 00:26:27,051
(apprehensive music)

386
00:26:27,086 --> 00:26:30,087
Good grazing is nearly
one and a half miles

387
00:26:30,122 --> 00:26:31,855
from the safety of the river.

388
00:26:32,725 --> 00:26:35,392
(hippo grumbling)

389
00:26:35,428 --> 00:26:39,330
But it's too hot to make
the journey in daytime.

390
00:26:39,365 --> 00:26:42,299
(hippos grumbling)

391
00:26:44,904 --> 00:26:47,571
she must wait until nightfall.

392
00:26:47,607 --> 00:26:51,542
(apprehensive music continues)

393
00:26:58,918 --> 00:27:01,418
In the cool of the night,

394
00:27:01,454 --> 00:27:05,389
the surrounding bush comes
alive.

395
00:27:05,424 --> 00:27:07,758
(eerie music)

396
00:27:07,793 --> 00:27:11,528
But with darkness comes the
unknown.

397
00:27:12,431 --> 00:27:15,265
(animal growling)

398
00:27:16,202 --> 00:27:19,303
(apprehensive music)

399
00:27:21,841 --> 00:27:24,074
Like it or not, the hippos

400
00:27:24,110 --> 00:27:26,377
must leave the safety of their
pool

401
00:27:28,514 --> 00:27:32,116
and head into the night in
search of food.

402
00:27:32,151 --> 00:27:34,051
(apprehensive music)

403
00:27:34,086 --> 00:27:36,220
(water splashing)

404
00:27:36,255 --> 00:27:38,288
(apprehensive music)

405
00:27:38,324 --> 00:27:41,258
The mother must not leave her
calf alone.

406
00:27:41,293 --> 00:27:44,461
So the pair begin the
slow and uncertain walk

407
00:27:44,497 --> 00:27:46,630
to find distant grazing.

408
00:27:47,633 --> 00:27:48,432
(apprehensive music)

409
00:27:48,467 --> 00:27:50,801
(hippo grumbling) (birds
squeaking)

410
00:27:50,836 --> 00:27:54,471
(animals snarling)

411
00:27:54,507 --> 00:27:57,341
(animal snarling)

412
00:27:58,277 --> 00:28:01,045
(animal grunting)

413
00:28:01,080 --> 00:28:04,148
(apprehensive music)
(animals grunting)

414
00:28:04,183 --> 00:28:06,050
(animal squawking)

415
00:28:06,085 --> 00:28:07,184
(animal growling)

416
00:28:07,219 --> 00:28:08,018
(animal squawking)

417
00:28:08,054 --> 00:28:09,353
(apprehensive music)

418
00:28:09,388 --> 00:28:12,322
(animals squawking) (animals
grumbling)

419
00:28:12,358 --> 00:28:14,992
(animal snarling)

420
00:28:15,027 --> 00:28:18,128
(apprehensive music)

421
00:28:19,532 --> 00:28:22,833
There is some safety in
numbers close to the water.

422
00:28:24,570 --> 00:28:27,237
But this far into the dry
season,

423
00:28:27,273 --> 00:28:30,140
the best food is further away.

424
00:28:30,176 --> 00:28:33,077
(animal squawking)

425
00:28:35,047 --> 00:28:37,548
Their size offers them some
protection.

426
00:28:42,388 --> 00:28:43,721
(apprehensive music)

427
00:28:43,756 --> 00:28:46,790
The hippo mother is a
formidable bodyguard.

428
00:28:48,360 --> 00:28:52,963
Her mouth is filled with
20 centimetre ivory tusks

429
00:28:52,998 --> 00:28:55,265
that serve only for defence.

430
00:28:56,235 --> 00:28:57,134
(apprehensive music)

431
00:28:57,169 --> 00:28:59,603
But a young hippo is vulnerable.

432
00:29:01,807 --> 00:29:05,609
So the calf must never stray
too far from his mother.

433
00:29:05,644 --> 00:29:07,978
(animal bellowing)

434
00:29:08,013 --> 00:29:09,780
(grass rustling)

435
00:29:09,815 --> 00:29:12,916
(animal squawking)

436
00:29:12,952 --> 00:29:16,019
(apprehensive music)

437
00:29:24,530 --> 00:29:25,763
(grass rustling)

438
00:29:25,798 --> 00:29:28,532
(bird squawking)

439
00:29:29,869 --> 00:29:32,136
(bird squawking)

440
00:29:32,171 --> 00:29:35,272
(grass rustling)

441
00:29:35,307 --> 00:29:38,041
(apprehensive music)

442
00:29:38,077 --> 00:29:39,643
(grass rustling)

443
00:29:39,678 --> 00:29:42,780
(apprehensive music)

444
00:29:44,717 --> 00:29:49,820
There is an unnerving quietness
to the bush around her.

445
00:29:49,855 --> 00:29:52,923
(apprehensive music)

446
00:29:53,759 --> 00:29:56,727
But now, they are too far from
the water

447
00:29:56,762 --> 00:29:58,462
to seek refuge there.

448
00:29:59,865 --> 00:30:02,332
And their stalkers know this.

449
00:30:02,368 --> 00:30:05,135
(apprehensive music)

450
00:30:05,171 --> 00:30:08,205
(grass rustling)

451
00:30:08,240 --> 00:30:13,043
A nearby male also senses
danger, and he joins the mother.

452
00:30:13,979 --> 00:30:15,712
Even in small groups,

453
00:30:15,748 --> 00:30:19,149
hippos can defend themselves
against a single lion.

454
00:30:21,554 --> 00:30:24,021
But not against a pride.

455
00:30:28,427 --> 00:30:31,094
(lion snarling)

456
00:30:32,765 --> 00:30:35,699
The mother knows if they
all hold their ground,

457
00:30:35,734 --> 00:30:37,367
they might have a chance.

458
00:30:38,838 --> 00:30:41,738
(hippos grumbling)

459
00:30:49,448 --> 00:30:52,149
The less experienced male
panics.

460
00:30:52,184 --> 00:30:54,585
(hippo grumbling)

461
00:30:54,620 --> 00:30:56,620
(apprehensive music)

462
00:30:56,655 --> 00:30:58,622
And they lose their advantage.

463
00:30:58,657 --> 00:31:01,458
(hippos grumbling)

464
00:31:01,493 --> 00:31:02,292
(hippos grumbling)

465
00:31:02,328 --> 00:31:03,126
(calf grumbling)

466
00:31:03,162 --> 00:31:04,895
(hippos grumbling)

467
00:31:04,930 --> 00:31:07,865
(hippos grumbling)

468
00:31:14,173 --> 00:31:19,176
(lions snarling) (hippo
groaning)

469
00:31:22,982 --> 00:31:24,481
(sombre music)

470
00:31:24,516 --> 00:31:27,017
The body of a young male hippo

471
00:31:27,052 --> 00:31:29,953
will keep a pride fed for a
week.

472
00:31:39,231 --> 00:31:40,564
The mother and her calf

473
00:31:40,599 --> 00:31:42,666
return to the protection of
their pool.

474
00:31:45,504 --> 00:31:47,604
They have had a lucky escape.

475
00:31:55,781 --> 00:32:00,617
But the mother hippo's remaining
refuge will soon dry out.

476
00:32:04,790 --> 00:32:08,725
And she and her calf will have
to travel further and further

477
00:32:08,761 --> 00:32:09,593
into the unknown.

478
00:32:11,497 --> 00:32:13,931
They'll need to do this every
night.

479
00:32:22,207 --> 00:32:26,610
All parents need dedication
in the face of adversity.

480
00:32:30,883 --> 00:32:33,550
(hippo huffing)

481
00:32:35,554 --> 00:32:37,220
The quest for food

482
00:32:37,256 --> 00:32:42,259
can be a seemingly never ending
commitment for many parents.

483
00:32:42,528 --> 00:32:45,262
(birds chirping)

484
00:32:47,900 --> 00:32:52,903
And here in Namibia, one takes
that commitment to extremes.

485
00:33:02,181 --> 00:33:03,981
(web rustling)

486
00:33:04,016 --> 00:33:07,284
This female African social
spider

487
00:33:07,319 --> 00:33:09,720
laid her eggs just days ago.

488
00:33:11,790 --> 00:33:15,525
And now her brood of 30
spiderlings

489
00:33:15,561 --> 00:33:18,595
are dependent on her for food.

490
00:33:18,630 --> 00:33:21,465
(enchanted music)

491
00:33:28,640 --> 00:33:33,310
So in their early life, she
regurgitates a milky liquid

492
00:33:33,345 --> 00:33:36,847
which the spiderlings drink
directly from her mouth.

493
00:33:42,388 --> 00:33:46,656
They will grow to 10 times
this size in the coming weeks.

494
00:33:49,495 --> 00:33:50,994
To fuel such growth,

495
00:33:51,997 --> 00:33:54,698
she will need to leave
her nursery to hunt.

496
00:33:54,733 --> 00:33:58,402
(enchanted music continues)

497
00:34:06,211 --> 00:34:09,746
Luckily, this mother has
family she can rely on,

498
00:34:13,919 --> 00:34:18,288
50 fully grown adult
sisters who share her nest

499
00:34:21,060 --> 00:34:23,894
and who hunt in perfect unison.

500
00:34:26,231 --> 00:34:31,234
(lighthearted music) (web
rustling)

501
00:34:33,405 --> 00:34:38,408
(lighthearted music) (web
rustling)

502
00:34:39,912 --> 00:34:43,513
(lighthearted music) (web
rustling)

503
00:34:43,549 --> 00:34:45,916
By stopping simultaneously,

504
00:34:45,951 --> 00:34:48,618
they can listen with their feet

505
00:34:49,721 --> 00:34:53,957
to detect the whereabouts of
their prey in their vast nest.

506
00:34:53,992 --> 00:34:57,094
(web rustling)

507
00:34:57,129 --> 00:35:00,297
(apprehensive music)

508
00:35:03,035 --> 00:35:04,701
(web rustling)

509
00:35:04,736 --> 00:35:07,537
(enchanted music)

510
00:35:21,120 --> 00:35:23,420
Within weeks, her spiderlings

511
00:35:23,455 --> 00:35:26,123
are ready to start hunting for
themselves.

512
00:35:27,726 --> 00:35:31,795
And as they grow, her
offspring and all their cousins

513
00:35:31,830 --> 00:35:33,630
become insatiable.

514
00:35:34,800 --> 00:35:37,868
(apprehensive music)

515
00:35:40,706 --> 00:35:44,407
They're born with the ability
to hunt together as a pack,

516
00:35:44,443 --> 00:35:45,709
just like their mothers.

517
00:35:47,045 --> 00:35:49,246
(apprehensive music) (web
rustling)

518
00:35:49,281 --> 00:35:53,216
Only now, there are
over a thousand of them.

519
00:35:53,252 --> 00:35:54,784
(apprehensive music)

520
00:35:54,820 --> 00:35:57,387
(web rustling)

521
00:35:59,358 --> 00:36:04,361
(web rustling)
(apprehensive music)

522
00:36:04,596 --> 00:36:07,097
(fly buzzing)

523
00:36:13,872 --> 00:36:17,974
Her role is almost over,
which is just as well.

524
00:36:20,812 --> 00:36:22,812
Since laying her eggs,

525
00:36:22,848 --> 00:36:25,815
the mother's condition
has been deteriorating,

526
00:36:27,286 --> 00:36:30,287
and her movements have become
laboured.

527
00:36:32,257 --> 00:36:36,526
The demands of parenthood are
finally taking their toll.

528
00:36:36,562 --> 00:36:39,629
(sombre music)

529
00:36:39,665 --> 00:36:42,732
But she has one more
gift for her offspring,

530
00:36:45,070 --> 00:36:47,204
the only thing she has left.

531
00:36:53,245 --> 00:36:54,277
(apprehensive music)

532
00:36:54,313 --> 00:36:57,414
(web rustling)

533
00:36:57,449 --> 00:37:01,151
Her struggling appears
to mimic the vibrations

534
00:37:01,186 --> 00:37:03,520
of a distressed prey insect.

535
00:37:04,690 --> 00:37:06,323
(apprehensive music) (web
rustling)

536
00:37:06,358 --> 00:37:10,727
And her hungry spiderlings
descend en masse

537
00:37:10,762 --> 00:37:14,931
to their mother's dinner
table one last time.

538
00:37:14,967 --> 00:37:17,767
(apprehensive music)

539
00:37:17,803 --> 00:37:22,806
Only this time, she is the main
course.

540
00:37:24,376 --> 00:37:25,842
(apprehensive music)

541
00:37:25,877 --> 00:37:26,676
(web rustling)

542
00:37:26,712 --> 00:37:30,180
(suspenseful music)

543
00:37:30,215 --> 00:37:32,816
(web rustling)

544
00:37:37,623 --> 00:37:40,223
(web rustling)

545
00:37:50,636 --> 00:37:53,236
Hers is the ultimate sacrifice,

546
00:37:54,139 --> 00:37:57,240
born out of a need to ensure the
survival

547
00:37:57,276 --> 00:37:58,975
of the next generation.

548
00:37:59,011 --> 00:38:02,946
(apprehensive music continues)

549
00:38:07,619 --> 00:38:10,453
But the spiderlings are not yet
finished.

550
00:38:11,823 --> 00:38:14,891
(apprehensive music)

551
00:38:15,961 --> 00:38:18,561
They turn on their surviving
relatives,

552
00:38:20,032 --> 00:38:23,533
eating every adult in
the colony one by one,

553
00:38:29,941 --> 00:38:32,042
until the next generation

554
00:38:34,046 --> 00:38:36,212
is all that is left.

555
00:38:36,248 --> 00:38:39,015
(birds chirping)

556
00:38:46,224 --> 00:38:48,558
Parental sacrifice on this scale

557
00:38:48,593 --> 00:38:50,894
is rare in the natural world.

558
00:38:55,734 --> 00:38:58,702
Though there comes a time
in a parent's journey

559
00:38:58,737 --> 00:39:01,404
when all that effort seems worth
it.

560
00:39:02,874 --> 00:39:05,942
(lighthearted music)

561
00:39:15,420 --> 00:39:18,922
A female western lowland gorilla
in Gabon.

562
00:39:22,994 --> 00:39:26,496
She will help her young
for almost four years

563
00:39:26,531 --> 00:39:30,300
to learn the complexities of
living in their jungle home.

564
00:39:30,335 --> 00:39:34,537
(lighthearted music continues)

565
00:39:34,573 --> 00:39:37,273
But as he becomes more
independent,

566
00:39:37,309 --> 00:39:39,142
she must let go

567
00:39:40,278 --> 00:39:43,380
and allow him to acquire the
rules

568
00:39:43,415 --> 00:39:45,348
of a gorilla's social life.

569
00:39:49,354 --> 00:39:53,089
(gorilla squawking)

570
00:39:53,125 --> 00:39:56,126
(gorilla squawking)

571
00:40:00,499 --> 00:40:02,732
His newfound independence

572
00:40:02,768 --> 00:40:06,336
triggers a crucial moment
in his mother's journey.

573
00:40:07,272 --> 00:40:09,906
(lighthearted music continues)

574
00:40:09,941 --> 00:40:11,374
It gives her the chance

575
00:40:11,410 --> 00:40:14,310
to think about her next
stage of parenthood.

576
00:40:17,582 --> 00:40:19,115
(lighthearted music)

577
00:40:19,151 --> 00:40:21,050
The father of her young one

578
00:40:21,086 --> 00:40:23,253
is reaching the end of his
prime.

579
00:40:27,292 --> 00:40:31,060
At 34, he's old for a
silverback.

580
00:40:33,899 --> 00:40:37,901
And unbeknownst to him, he
is under constant assessment.

581
00:40:40,439 --> 00:40:43,773
Female lowland gorillas
will leave their troop

582
00:40:43,809 --> 00:40:46,209
if they think there
might be better options.

583
00:40:46,244 --> 00:40:47,710
(lighthearted music)

584
00:40:47,746 --> 00:40:51,714
And that decision all
boils down to one thing.

585
00:40:54,419 --> 00:40:56,052
Has he still got it?

586
00:40:57,189 --> 00:40:57,987
(gorilla huffing)

587
00:40:58,023 --> 00:40:58,822
(lighthearted music)

588
00:40:58,857 --> 00:41:00,657
(gorilla grumbling)

589
00:41:00,692 --> 00:41:01,791
Hmm, not bad.

590
00:41:05,163 --> 00:41:06,396
(lighthearted music)

591
00:41:06,431 --> 00:41:09,933
Her offspring will inherit
his excellent physique,

592
00:41:10,969 --> 00:41:13,369
giving him a good headstart in
life.

593
00:41:18,944 --> 00:41:19,909
(leaves rustling)
(ground thudding)

594
00:41:19,945 --> 00:41:21,678
(gorilla squeaking)

595
00:41:21,713 --> 00:41:24,547
(leaves rustling)

596
00:41:25,951 --> 00:41:29,619
Brawn isn't the only thing she
considers.

597
00:41:29,654 --> 00:41:30,954
(lighthearted music)

598
00:41:30,989 --> 00:41:34,691
Though males play a little part
in raising their offspring,

599
00:41:34,726 --> 00:41:38,828
females nonetheless prefer males
with a degree of tolerance.

600
00:41:41,199 --> 00:41:42,932
(gorilla huffing)

601
00:41:42,968 --> 00:41:46,503
And the old silverback has
always been good with kids.

602
00:41:46,538 --> 00:41:50,173
(lighthearted music)

603
00:41:50,208 --> 00:41:52,542
(gorilla squeaking)

604
00:41:52,577 --> 00:41:53,376
(leaves rustling)
(gorilla grumbling)

605
00:41:53,411 --> 00:41:55,612
(gorilla squeaking)

606
00:41:55,647 --> 00:41:58,481
(leaves rustling)

607
00:41:58,517 --> 00:42:01,518
(gorilla grumbling)

608
00:42:02,988 --> 00:42:05,121
On top of his physique and
character,

609
00:42:06,124 --> 00:42:08,224
she's also constantly assessing

610
00:42:08,260 --> 00:42:10,226
what his territory has to offer.

611
00:42:13,398 --> 00:42:16,466
(lighthearted music)

612
00:42:19,337 --> 00:42:21,170
Wherever it comes from,

613
00:42:24,142 --> 00:42:27,310
good and plentiful food is
crucial

614
00:42:27,345 --> 00:42:29,712
for any mother trying to raise
her young.

615
00:42:33,652 --> 00:42:36,719
(lighthearted music)

616
00:42:38,590 --> 00:42:39,556
(lighthearted music)

617
00:42:39,591 --> 00:42:42,292
And variety helps
parents teach their young

618
00:42:42,327 --> 00:42:45,094
about what to eat and where to
find it.

619
00:42:47,933 --> 00:42:51,701
In the food department, he
scores highly.

620
00:42:51,736 --> 00:42:54,604
(lighthearted music)

621
00:42:54,639 --> 00:42:57,707
(lighthearted music)

622
00:43:03,949 --> 00:43:05,515
(lighthearted music)

623
00:43:05,550 --> 00:43:07,216
He even has a swamp,

624
00:43:09,254 --> 00:43:11,387
which might not sound like much,

625
00:43:13,191 --> 00:43:16,993
but the grasses here
provide much needed protein

626
00:43:17,028 --> 00:43:19,195
to a lowland gorilla's diet.

627
00:43:24,202 --> 00:43:28,204
She also is looking for
protection when life gets risky.

628
00:43:30,342 --> 00:43:32,041
(apprehensive music)

629
00:43:32,077 --> 00:43:34,210
(elephant roaring)

630
00:43:34,245 --> 00:43:35,979
(chest thudding)

631
00:43:36,014 --> 00:43:39,315
(elephant grumbling)

632
00:43:39,351 --> 00:43:42,418
A forest elephant is not
immediate competition

633
00:43:42,454 --> 00:43:45,922
but a threat to young
gorillas nonetheless.

634
00:43:47,292 --> 00:43:50,360
(elephant grumbling)

635
00:43:52,464 --> 00:43:55,665
(gorilla huffing)

636
00:43:55,700 --> 00:43:57,700
(gorilla grumbling)

637
00:43:57,736 --> 00:44:00,870
Willingness to stand up
to those bigger than him

638
00:44:00,905 --> 00:44:02,872
is certainly attractive in a
partner.

639
00:44:10,215 --> 00:44:13,316
(lighthearted music)

640
00:44:14,152 --> 00:44:16,486
If she chose to leave, however,

641
00:44:16,521 --> 00:44:19,022
there would be significant
risks.

642
00:44:24,529 --> 00:44:27,463
Any new male with whom she
associates

643
00:44:27,499 --> 00:44:29,999
could kill infants that aren't
his own.

644
00:44:31,803 --> 00:44:34,604
So she'll have to leave her
child behind.

645
00:44:36,174 --> 00:44:40,910
And it would months to establish
herself within a new troop.

646
00:44:42,514 --> 00:44:43,413
(gorilla grumbling)

647
00:44:43,448 --> 00:44:47,250
Here, at least she already has a
partner,

648
00:44:48,586 --> 00:44:51,320
just a slightly mature one.

649
00:44:51,356 --> 00:44:56,125
(gorilla chattering)
(lighthearted music)

650
00:44:56,161 --> 00:44:59,896
For now, it seems he has passed
her test.

651
00:45:00,799 --> 00:45:03,800
(gorilla grumbling)

652
00:45:06,671 --> 00:45:10,173
But there's still time to change
her mind.

653
00:45:10,208 --> 00:45:13,209
(gorilla grumbling)

654
00:45:14,646 --> 00:45:18,481
(lighthearted music)

655
00:45:18,516 --> 00:45:21,951
Parental strategies have
evolved over millennia.

656
00:45:24,923 --> 00:45:28,357
But now, over 80% of the Earth's
land mass

657
00:45:28,393 --> 00:45:31,360
is affected by human activity.

658
00:45:32,897 --> 00:45:36,499
And animal parents are having
to adapt to this new world.

659
00:45:44,976 --> 00:45:47,877
(melancholy music)

660
00:45:50,749 --> 00:45:53,282
An endangered Iberian Lynx

661
00:45:54,319 --> 00:45:55,585
known as Odrina.

662
00:46:07,398 --> 00:46:11,701
This abandoned barn is the
best place left for Odrina

663
00:46:11,736 --> 00:46:13,402
to raise her five kittens.

664
00:46:15,673 --> 00:46:18,241
(cubs purring)

665
00:46:19,878 --> 00:46:23,913
It's an excellent refuge
for her growing family,

666
00:46:23,948 --> 00:46:25,915
cool, sheltered,

667
00:46:26,885 --> 00:46:30,386
and full of activities for soft
play.

668
00:46:30,421 --> 00:46:33,389
(cub hissing)
(lighthearted music)

669
00:46:33,424 --> 00:46:38,327
In fact, this place is so
good that Odrina is not alone.

670
00:46:39,197 --> 00:46:41,230
Both her mother and her daughter

671
00:46:41,266 --> 00:46:43,666
have chosen to raise their
kittens here.

672
00:46:48,273 --> 00:46:51,674
Three generations raising
their young together,

673
00:46:54,979 --> 00:46:57,613
a rare phenomenon and a sign of
hope.

674
00:47:01,986 --> 00:47:06,255
But the recovery of lynx
here has only been possible

675
00:47:06,291 --> 00:47:09,192
by what has happened outside the
barn.

676
00:47:11,362 --> 00:47:14,197
(engine rumbling)

677
00:47:15,867 --> 00:47:18,701
Less than a decade ago, the
farmers here

678
00:47:18,736 --> 00:47:20,937
chose to change their practise

679
00:47:20,972 --> 00:47:24,106
to suit the native wild animals.

680
00:47:24,142 --> 00:47:26,843
(lighthearted music)

681
00:47:26,878 --> 00:47:28,544
They stopped hunting

682
00:47:28,580 --> 00:47:32,582
and began creating habitat
amongst their crops.

683
00:47:32,617 --> 00:47:35,451
(engine rumbling)

684
00:47:36,588 --> 00:47:39,388
And quicker than anyone had
imagined,

685
00:47:39,424 --> 00:47:43,025
the native animals moved back
in.

686
00:47:45,129 --> 00:47:46,529
First prey,

687
00:47:47,966 --> 00:47:49,232
then predators.

688
00:47:51,169 --> 00:47:55,471
Soon, the farm became a safe
refuge for parents like Odrina

689
00:47:55,506 --> 00:47:57,173
to introduce their kittens

690
00:47:57,208 --> 00:48:01,377
to a world that had been
redesigned with them in mind,

691
00:48:05,149 --> 00:48:08,618
one where kittens have room to
explore,

692
00:48:11,956 --> 00:48:12,788
play,

693
00:48:15,193 --> 00:48:16,359
and hunt.

694
00:48:16,394 --> 00:48:19,896
(lighthearted music continues)

695
00:48:19,931 --> 00:48:21,030
And they thrived.

696
00:48:25,069 --> 00:48:27,036
We are beginning to understand

697
00:48:27,071 --> 00:48:30,206
that it's possible to use
our world for our needs

698
00:48:31,910 --> 00:48:35,044
but also providing for wild
animals.

699
00:48:40,685 --> 00:48:43,252
And we are discovering that by
doing so,

700
00:48:43,288 --> 00:48:46,355
it's possible to help other
species.

701
00:48:47,926 --> 00:48:50,693
(majestic music)

702
00:48:57,669 --> 00:49:02,471
Iberian lynx have begun
a remarkable recovery,

703
00:49:02,507 --> 00:49:05,608
but their fate still
remains in the balance.

704
00:49:09,647 --> 00:49:13,816
The future is uncertain for
all parents across our world.

705
00:49:16,287 --> 00:49:20,323
But what is clear is that
for all of us to survive,

706
00:49:20,358 --> 00:49:22,525
we will need to help each other.

707
00:49:22,560 --> 00:49:26,128
(majestic music continues)

708
00:49:31,302 --> 00:49:34,070
(rhythmic music)

709
00:49:38,543 --> 00:49:43,045
The "Parenthood" team relied
on experts all over the world.

710
00:49:48,886 --> 00:49:50,119
(team member imitates croaking)

711
00:49:50,154 --> 00:49:52,355
(frog croaking)

712
00:49:52,390 --> 00:49:54,957
And in Loango National Park in
Gabon,

713
00:49:55,860 --> 00:49:59,128
primatologist Dr. Martha
Robbins and her team

714
00:49:59,163 --> 00:50:02,565
came with 20 years of crucial
expertise.

715
00:50:03,501 --> 00:50:06,302
- The idea behind this
project is to link research

716
00:50:06,337 --> 00:50:09,005
and conservation of western
gorillas.

717
00:50:09,040 --> 00:50:10,673
For this project to succeed,

718
00:50:10,708 --> 00:50:14,744
we need to work together
with Gabonese people.

719
00:50:14,779 --> 00:50:18,748
And the Babongo have
remarkable tracking abilities,

720
00:50:18,783 --> 00:50:21,784
where they can see things in
the forest that we can't see.

721
00:50:22,820 --> 00:50:25,421
(tracker speaking
in foreign language)

722
00:50:26,691 --> 00:50:28,157
- [Narrator] The Babongo
trackers

723
00:50:28,192 --> 00:50:31,527
take the lead daily into the
forest.

724
00:50:31,562 --> 00:50:34,163
And by snapping twigs as they go
along,

725
00:50:34,198 --> 00:50:37,033
they leave themselves
a trail to follow back.

726
00:50:37,068 --> 00:50:39,435
(lighthearted music)

727
00:50:39,470 --> 00:50:42,004
But it is their carefully
crafted relationship

728
00:50:42,040 --> 00:50:44,140
with the gorillas that is key.

729
00:50:48,012 --> 00:50:52,615
(Hermann speaking in foreign
language)

730
00:50:59,891 --> 00:51:02,725
- [Narrator] The trackers know
they must first help the crew

731
00:51:02,760 --> 00:51:05,294
gain the silverback's trust.

732
00:51:05,329 --> 00:51:07,997
(bird chirping)

733
00:51:09,600 --> 00:51:10,733
- Whoa.

734
00:51:10,768 --> 00:51:15,371
You could feel the power
of this massive creature.

735
00:51:15,406 --> 00:51:18,808
Silverbacks are probably the
most powerful of all primates.

736
00:51:18,843 --> 00:51:21,944
(lighthearted music)

737
00:51:23,181 --> 00:51:25,314
- [Narrator] And they warn the
crew

738
00:51:25,349 --> 00:51:27,116
it isn't going to come easy.

739
00:51:32,657 --> 00:51:37,226
(Hermann speaking in foreign
language)

740
00:51:40,264 --> 00:51:42,264
- [Martha] The gorillas
really like the swamps

741
00:51:42,300 --> 00:51:44,500
because it's full of tasty
gorilla food.

742
00:51:47,105 --> 00:51:49,338
The swamps don't pose
challenge for the gorillas.

743
00:51:49,373 --> 00:51:52,374
The swamps pose one of
many challenges for us.

744
00:51:54,979 --> 00:51:55,845
- [Peter] You okay?

745
00:51:55,880 --> 00:51:57,079
- Nope.

746
00:51:57,115 --> 00:51:59,982
(lighthearted music)

747
00:52:00,017 --> 00:52:03,452
- [Narrator] The team try
as best they can to keep up.

748
00:52:03,488 --> 00:52:05,821
And just as they reach dry land,

749
00:52:07,625 --> 00:52:10,793
the gorilla family have other
ideas.

750
00:52:12,497 --> 00:52:14,063
- So we've just crossed the
swamp.

751
00:52:14,098 --> 00:52:16,732
We've managed to find the
gorillas, which is great.

752
00:52:16,767 --> 00:52:17,967
The gorillas have decided

753
00:52:18,002 --> 00:52:20,169
that they're going to go
back across the same swamp

754
00:52:20,204 --> 00:52:21,170
that we've just crossed.

755
00:52:21,205 --> 00:52:23,939
So, yeah, we're gonna follow
them across

756
00:52:23,975 --> 00:52:24,974
and do it all again.

757
00:52:26,544 --> 00:52:27,977
- [Narrator] Back on the other
side,

758
00:52:28,012 --> 00:52:30,346
they catch a fleeting glimpse.

759
00:52:30,381 --> 00:52:33,449
But the gorillas have yet to
accept the crew's presence,

760
00:52:33,484 --> 00:52:35,651
and disappear into the forest.

761
00:52:37,488 --> 00:52:39,455
- So back to searching.

762
00:52:39,490 --> 00:52:42,892
(birds chirping)

763
00:52:42,927 --> 00:52:45,594
- [Narrator] They tracked
down the gorillas once again.

764
00:52:45,630 --> 00:52:48,697
But if the crew thought
the swamps were hard work,

765
00:52:48,733 --> 00:52:51,000
the mangroves are even trickier.

766
00:52:53,738 --> 00:52:56,138
And once again, the crew are
left trailing

767
00:52:56,174 --> 00:52:57,706
in the gorillas wake.

768
00:53:00,545 --> 00:53:04,380
Frustratingly, they decide
to abandon the day's search.

769
00:53:05,516 --> 00:53:08,584
(lighthearted music)

770
00:53:09,520 --> 00:53:11,754
A new day, a new lead.

771
00:53:13,891 --> 00:53:17,426
The trackers' familiarity
with the gorilla's movements

772
00:53:17,461 --> 00:53:19,261
continues to be essential.

773
00:53:21,999 --> 00:53:26,735
(Hermann speaking in foreign
language)

774
00:53:26,771 --> 00:53:27,937
- [Narrator] But the silverback

775
00:53:27,972 --> 00:53:30,272
is still unsure about the
cameras

776
00:53:30,308 --> 00:53:32,474
and keeps his family moving.

777
00:53:32,510 --> 00:53:34,577
- I have seen the silverback's
bum.

778
00:53:35,613 --> 00:53:37,246
Quite special already, I guess.

779
00:53:40,017 --> 00:53:41,317
- [Narrator] The science team

780
00:53:41,352 --> 00:53:44,587
spot a potential obstacle
on the path ahead.

781
00:53:44,622 --> 00:53:47,756
(apprehensive music)
(elephant grumbling)

782
00:53:47,792 --> 00:53:52,361
(Hermann speaking
in foreign language)

783
00:53:54,498 --> 00:53:56,332
(elephant grumbling)

784
00:53:56,367 --> 00:54:01,537
(Hermann speaking in foreign
language)

785
00:54:20,291 --> 00:54:22,091
(apprehensive music)

786
00:54:22,126 --> 00:54:25,294
- There's nothing worse
than an angry elephant,

787
00:54:25,329 --> 00:54:27,663
so now we're just making our way
around

788
00:54:27,698 --> 00:54:29,932
so that we didn't get in
their way or disturb them.

789
00:54:29,967 --> 00:54:33,035
(elephant grumbling)

790
00:54:34,372 --> 00:54:36,739
- [Narrator] Luckily, it isn't
a problem for the trackers

791
00:54:36,774 --> 00:54:38,340
to pick up the trail again.

792
00:54:39,810 --> 00:54:42,711
- Fastan just pointed out
a track that he just found,

793
00:54:42,747 --> 00:54:44,880
and this is the trace that he
sees.

794
00:54:48,019 --> 00:54:50,152
- [Narrator] A moment
of calm in the forest

795
00:54:50,187 --> 00:54:52,755
allows the crew to finally set
up.

796
00:54:52,790 --> 00:54:53,822
(rain pattering)

797
00:54:53,858 --> 00:54:57,159
But just as they do so, the
rains arrive.

798
00:54:59,964 --> 00:55:03,299
A wet camera could spell the
end of their filming trip.

799
00:55:04,735 --> 00:55:05,668
(boat rumbling)

800
00:55:05,703 --> 00:55:07,870
So they're forced to retreat
once more.

801
00:55:10,107 --> 00:55:13,542
- Ah, it's so wet. (chuckles)

802
00:55:14,478 --> 00:55:17,379
(mystical music)

803
00:55:17,415 --> 00:55:18,914
- [Narrator] Overnight, the
rains

804
00:55:18,949 --> 00:55:21,150
have washed away the
tracks of the gorillas.

805
00:55:25,890 --> 00:55:28,490
But the trackers pick up another
sign.

806
00:55:32,930 --> 00:55:35,964
The freshly stripped
twigs indicate gorillas

807
00:55:36,000 --> 00:55:37,833
have recently been feeding here.

808
00:55:41,605 --> 00:55:44,707
(lighthearted music)

809
00:55:48,979 --> 00:55:51,180
And now it seems the silverback

810
00:55:51,215 --> 00:55:54,450
is willing to finally
allow the crew access.

811
00:55:58,923 --> 00:56:00,923
- So cool, so cool.

812
00:56:00,958 --> 00:56:02,658
- [Narrator] Over the following
weeks,

813
00:56:02,693 --> 00:56:04,760
the science team helps the crew

814
00:56:04,795 --> 00:56:07,162
to understand the gorillas'
behaviour.

815
00:56:08,332 --> 00:56:10,699
- A big reward is discovering
new things

816
00:56:10,735 --> 00:56:12,634
that we don't know about these
animals.

817
00:56:12,670 --> 00:56:15,104
There's something every
day that the gorillas do

818
00:56:15,139 --> 00:56:17,306
that can put a smile on your
face.

819
00:56:17,341 --> 00:56:18,807
(lighthearted music continues)

820
00:56:18,843 --> 00:56:22,378
- This shoot would've obviously
been impossible for us

821
00:56:22,413 --> 00:56:26,181
without the help of all the
amazing guides

822
00:56:26,217 --> 00:56:27,516
and trackers we had.

823
00:56:28,786 --> 00:56:32,521
(Hermann speaking in foreign
language)

824
00:57:02,253 --> 00:57:05,320
(lighthearted music)

825
00:57:22,306 --> 00:57:25,073
(majestic music)
