1
00:00:02,160 --> 00:00:05,659
The world is full of
extraordinary animals.
2
00:00:07,891 --> 00:00:10,757
But how well do we
really understand them?
3
00:00:11,892 --> 00:00:14,258
How do they
really think and feel?
4
00:00:15,325 --> 00:00:16,624
To find out,
5
00:00:16,691 --> 00:00:19,825
a team of spy creatures
is going undercover.
6
00:00:21,791 --> 00:00:24,390
They not only look
like part of the family,
7
00:00:24,460 --> 00:00:26,290
they behave like them, too.
8
00:00:29,359 --> 00:00:31,924
Armed with the latest
camera technology,
9
00:00:31,991 --> 00:00:35,589
they are going
to travel the globe
10
00:00:35,659 --> 00:00:39,791
to understand the true nature
of the animals they meet
11
00:00:39,858 --> 00:00:43,060
and reveal how intelligent
they really are.
12
00:00:46,043 --> 00:00:48,510
How badly behaved they can be.
13
00:00:50,342 --> 00:00:53,342
How important
friendship is to them.
14
00:00:55,310 --> 00:00:56,509
And if it's possible
15
00:00:56,577 --> 00:00:58,742
that they can
truly love each other.
16
00:00:59,776 --> 00:01:01,009
What they discover
17
00:01:01,076 --> 00:01:03,975
will change our perception
of animals for ever.
18
00:01:07,368 --> 00:01:08,799
Perhaps they are more like us
19
00:01:08,867 --> 00:01:11,033
than we ever
believed possible.
20
00:01:22,500 --> 00:01:25,600
Animals often have
strong family bonds,
21
00:01:25,668 --> 00:01:29,833
but how important are the other
relationships in their lives?
22
00:01:33,234 --> 00:01:36,034
The Kalahari Desert of Africa,
23
00:01:36,100 --> 00:01:38,033
home to the meerkat.
24
00:01:42,766 --> 00:01:44,467
Here, everyone
helps each other
25
00:01:44,534 --> 00:01:46,832
and life revolves
around the queen,
26
00:01:46,900 --> 00:01:49,567
the only female
to have babies.
27
00:01:52,466 --> 00:01:57,366
She can have six in a litter
and three litters in a year,
28
00:01:57,435 --> 00:02:00,067
so her many offspring
are everywhere.
29
00:02:01,900 --> 00:02:04,432
They need
a lot of looking after.
30
00:02:06,034 --> 00:02:10,399
But fortunately, she has
plenty of friends to help,
31
00:02:10,467 --> 00:02:12,499
up to 50 of them.
32
00:02:16,368 --> 00:02:19,067
And today, she has one more.
33
00:02:23,135 --> 00:02:24,865
A spy meerkat.
34
00:02:26,733 --> 00:02:29,165
She is here to film
the unique friendship
35
00:02:29,233 --> 00:02:32,468
that exists among these
highly sociable animals.
36
00:02:36,734 --> 00:02:38,700
But this is
a tight-knit community,
37
00:02:38,769 --> 00:02:40,933
they don't welcome strangers.
38
00:02:52,201 --> 00:02:55,665
She is the biggest meerkat
they've ever seen,
39
00:02:55,735 --> 00:02:58,601
and requires
serious examination.
40
00:03:02,467 --> 00:03:04,698
She's been made
to smell like the colony,
41
00:03:04,765 --> 00:03:06,433
so this reassures them.
42
00:03:14,100 --> 00:03:17,332
Each day, different
volunteers set up a creche,
43
00:03:17,400 --> 00:03:21,232
giving all the child support
a mother could wish for.
44
00:03:21,301 --> 00:03:24,865
They share roles
including sentry duty.
45
00:03:26,301 --> 00:03:30,700
It demands concentration
and it's easy to lose focus.
46
00:03:39,434 --> 00:03:40,667
And sometimes it's good
47
00:03:40,733 --> 00:03:42,932
to have someone
watching your back.
48
00:03:44,035 --> 00:03:46,434
Being a sentry
is a risky business
49
00:03:46,501 --> 00:03:49,599
as they are easy targets
for predators.
50
00:03:49,667 --> 00:03:51,498
But with young pups
to protect,
51
00:03:51,568 --> 00:03:54,600
they take greater risks
by climbing higher.
52
00:03:54,666 --> 00:03:57,533
Here, they can
see predators earlier,
53
00:03:57,600 --> 00:04:00,734
but are vulnerable
to birds of prey.
54
00:04:00,801 --> 00:04:04,001
Their self-sacrifice
is about to be tested.
55
00:04:11,001 --> 00:04:12,964
But this is no ordinary cobra.
56
00:04:13,034 --> 00:04:14,865
It's a spy cobra.
57
00:04:16,067 --> 00:04:18,498
With no regard
for her own safety,
58
00:04:18,567 --> 00:04:20,866
she prepares
to face the snake.
59
00:04:41,566 --> 00:04:44,098
She reacts as she would
to the real thing,
60
00:04:44,167 --> 00:04:48,067
bravely protecting the colony
with no thought for herself.
61
00:04:52,902 --> 00:04:56,500
Her aim is to harass
the snake into leaving,
62
00:04:56,566 --> 00:04:59,432
but with spy snake
holding its ground,
63
00:04:59,502 --> 00:05:01,934
the meerkat calls
for reinforcements.
64
00:05:05,667 --> 00:05:08,532
This is where fraternity
comes into its own.
65
00:05:23,936 --> 00:05:26,534
An intimidating
wall of meerkats
66
00:05:26,600 --> 00:05:28,699
face up to spy cobra.
67
00:05:39,135 --> 00:05:41,766
They push their luck
as far as they dare,
68
00:05:41,834 --> 00:05:43,798
goading the snake to strike.
69
00:05:50,633 --> 00:05:52,599
Real snakes tire easily,
70
00:05:52,667 --> 00:05:55,367
so it's a matter
of wearing it down.
71
00:06:00,868 --> 00:06:02,166
But one meerkat
72
00:06:02,233 --> 00:06:05,066
senses there's something
different about this serpent.
73
00:06:08,001 --> 00:06:11,134
It may look and move
like a real snake,
74
00:06:11,202 --> 00:06:13,867
but it shows
no sign of leaving.
75
00:06:19,866 --> 00:06:23,600
Spy snake has been
well and truly rumbled.
76
00:06:31,599 --> 00:06:33,832
Satisfied he's harmless,
77
00:06:33,901 --> 00:06:37,335
the meerkats go back
to what they enjoy best,
78
00:06:38,400 --> 00:06:40,399
relaxing among friends.
79
00:06:43,599 --> 00:06:47,733
And there's a more approachable
spy creature to spend time with.
80
00:06:49,001 --> 00:06:52,034
Even the pups
get their own introduction.
81
00:06:58,535 --> 00:07:00,300
She's part of the gang now,
82
00:07:00,368 --> 00:07:04,500
perfectly placed to film more of
the meerkats' close alliances.
83
00:07:14,069 --> 00:07:16,467
The extremes of
the Canadian Arctic
84
00:07:16,534 --> 00:07:18,267
present different challenges.
85
00:07:24,069 --> 00:07:26,834
These wolves are all related,
86
00:07:26,901 --> 00:07:29,299
but it's the close friendships
between them
87
00:07:29,367 --> 00:07:30,801
that really count.
88
00:07:34,133 --> 00:07:35,600
In this harsh world,
89
00:07:35,667 --> 00:07:38,699
it's vital they work together
to find and catch food,
90
00:07:38,766 --> 00:07:41,933
and the mother needs support
in bringing up her cubs.
91
00:07:54,033 --> 00:07:57,998
A new spy creature
attempts to join the pack.
92
00:08:01,467 --> 00:08:05,098
Spy wolf cub
may not last long.
93
00:08:05,167 --> 00:08:07,767
Wolves kill strange cubs.
94
00:08:19,335 --> 00:08:22,867
She considers
how to deal with him.
95
00:08:22,934 --> 00:08:25,601
Then pees on him instead.
96
00:08:27,668 --> 00:08:29,767
Not the most fragrant welcome,
97
00:08:29,836 --> 00:08:31,968
but smelling
of wolf is an advantage
98
00:08:32,034 --> 00:08:34,766
if you want to make friends
with wolf cubs.
99
00:08:40,768 --> 00:08:44,001
He soon gets a cub's-eye view
of the family.
100
00:08:55,168 --> 00:08:56,702
At five weeks old,
101
00:08:56,768 --> 00:08:59,366
the cubs need more than
just mother's milk,
102
00:08:59,434 --> 00:09:01,766
so the wolves must go hunting.
103
00:09:01,835 --> 00:09:03,600
They rally the pack.
104
00:09:03,668 --> 00:09:05,598
This is when
friendships really matter
105
00:09:05,667 --> 00:09:07,335
and everyone must take part.
106
00:09:09,436 --> 00:09:11,368
The cubs are left behind.
107
00:09:11,433 --> 00:09:14,467
They have the den
to keep them safe
108
00:09:14,535 --> 00:09:17,868
and a new friend to keep
a spying eye on them.
109
00:09:21,203 --> 00:09:22,967
In the height
of the Arctic summer,
110
00:09:23,035 --> 00:09:25,166
mosquitoes become a problem.
111
00:09:27,301 --> 00:09:29,233
A few might be a nuisance.
112
00:09:32,701 --> 00:09:35,600
But a plague
can be devastating.
113
00:09:37,267 --> 00:09:40,865
These bloodsucking insects
can weaken and even kill.
114
00:09:43,400 --> 00:09:46,301
Already the cubs
are suffering.
115
00:09:53,968 --> 00:09:56,868
Only the den
offers some sanctuary.
116
00:09:59,868 --> 00:10:01,799
The father has been
out scavenging
117
00:10:01,867 --> 00:10:04,600
and returns to see
the growing swarm.
118
00:10:10,067 --> 00:10:12,734
This is not a place
for young cubs any more.
119
00:10:18,068 --> 00:10:20,400
So without waiting
for the rest of the pack,
120
00:10:20,467 --> 00:10:22,532
he decides they must be moved.
121
00:10:22,602 --> 00:10:24,834
But the nearest
alternative den
122
00:10:24,901 --> 00:10:26,334
is five miles away.
123
00:10:27,234 --> 00:10:29,032
He sets a punishing pace.
124
00:10:29,100 --> 00:10:30,667
Wolves travel fast.
125
00:10:32,500 --> 00:10:34,332
And the cubs are struggling.
126
00:10:39,235 --> 00:10:41,800
The smallest
soon drops behind.
127
00:10:46,367 --> 00:10:49,032
After running
for over two miles,
128
00:10:49,102 --> 00:10:50,468
he's had enough.
129
00:10:54,102 --> 00:10:57,934
The father conceals him
in a temporary hideaway,
130
00:10:58,000 --> 00:11:00,299
somewhere to regain
his strength.
131
00:11:04,134 --> 00:11:07,766
With the little cub safe,
he continues his journey.
132
00:11:11,068 --> 00:11:12,467
After five miles,
133
00:11:12,534 --> 00:11:14,632
the father finally
slows the pace
134
00:11:14,702 --> 00:11:17,802
and the remaining two cubs
reach the new den.
135
00:11:17,868 --> 00:11:20,267
There are far less
mosquitoes here.
136
00:11:24,134 --> 00:11:27,133
The cubs are now in need
of a good meal.
137
00:11:27,200 --> 00:11:28,334
Without hesitation,
138
00:11:28,403 --> 00:11:30,734
the father
sets off to find one.
139
00:11:34,400 --> 00:11:36,432
Spy cub is still
at the old den
140
00:11:36,500 --> 00:11:38,933
as the mother
and the pack arrive back.
141
00:11:43,767 --> 00:11:46,868
They soon realise
the cubs are missing.
142
00:11:50,102 --> 00:11:51,800
The mother calls for her cubs.
143
00:11:56,901 --> 00:11:59,600
The pack spread out
looking for scent trails.
144
00:12:01,135 --> 00:12:03,267
Everyone is working together.
145
00:12:14,035 --> 00:12:17,101
After searching
for eight long hours,
146
00:12:17,167 --> 00:12:19,733
at last they find the new den.
147
00:12:25,767 --> 00:12:28,735
But they soon realise
one cub is missing.
148
00:12:32,336 --> 00:12:35,003
The pack howls
for the lost cub.
149
00:12:37,701 --> 00:12:41,068
They won't give up searching
until everyone is reunited.
150
00:12:45,935 --> 00:12:48,768
As the mother sets off
with the rest of the pack,
151
00:12:48,834 --> 00:12:51,767
she entrusts her cubs
to her closest friend.
152
00:12:55,469 --> 00:12:57,199
She acts as a surrogate mother
153
00:12:57,268 --> 00:13:00,966
and produces milk so she can
help out in times of need.
154
00:13:04,402 --> 00:13:06,334
Even with all
the pack involved,
155
00:13:06,403 --> 00:13:11,002
finding the lost cub in this vast
wilderness will be challenging.
156
00:13:24,301 --> 00:13:27,765
The African Savanna creates
its own challenges
157
00:13:27,834 --> 00:13:29,200
and it's given rise to some
158
00:13:29,268 --> 00:13:31,769
strange and unique
partnerships.
159
00:13:33,735 --> 00:13:36,635
When male warthogs
leave the family home,
160
00:13:36,701 --> 00:13:40,233
they find company
with similar lost souls.
161
00:13:40,302 --> 00:13:42,067
They hang around in gangs,
162
00:13:42,136 --> 00:13:45,434
rooting for food and indulging
in their favourite pastime,
163
00:13:45,501 --> 00:13:47,300
mud bathing.
164
00:13:54,436 --> 00:13:57,569
It's the perfect place
for some male bonding.
165
00:13:59,836 --> 00:14:01,634
But since
they left the family,
166
00:14:01,702 --> 00:14:03,967
this is a sight
they rarely see,
167
00:14:04,034 --> 00:14:05,967
a young warthog on its own.
168
00:14:14,036 --> 00:14:16,501
Spy warthog may soon discover
169
00:14:16,568 --> 00:14:19,035
just how friendly
they really are.
170
00:14:25,869 --> 00:14:28,534
He's certainly creating
some interest.
171
00:14:40,501 --> 00:14:44,668
It's been a long time since this
male has met a young warthog.
172
00:14:52,335 --> 00:14:54,432
Nuzzling is a greeting.
173
00:14:54,501 --> 00:14:56,934
Warthogs use
their sensitive noses
174
00:14:57,003 --> 00:14:58,436
to recognise each other.
175
00:15:08,770 --> 00:15:11,901
Remarkably, he seems
to be welcome here.
176
00:15:22,134 --> 00:15:25,833
He's now a junior member
of the gang.
177
00:15:25,903 --> 00:15:28,668
But they are not the only
friends he needs to make.
178
00:15:35,467 --> 00:15:38,669
These lively characters
are banded mongoose.
179
00:15:43,969 --> 00:15:47,900
And they and the warthogs
are the best of buddies.
180
00:15:47,968 --> 00:15:52,535
Their partnership is one of the
most surprising in nature.
181
00:15:55,802 --> 00:15:59,933
When the warthog lies down,
it's a signal to the mongoose.
182
00:16:01,770 --> 00:16:04,335
It means
he wants to be groomed.
183
00:16:12,401 --> 00:16:16,600
The mongoose sets to work,
removing dry or flaky skin
184
00:16:16,667 --> 00:16:20,433
and ferreting out parasites
like ticks and fleas.
185
00:16:25,936 --> 00:16:28,534
They may act
as skin therapists,
186
00:16:28,601 --> 00:16:30,866
but they don't
go easy on their clients.
187
00:16:36,269 --> 00:16:37,868
It's for their own good
188
00:16:37,934 --> 00:16:40,968
and the mongoose
get a meal as payment.
189
00:16:43,800 --> 00:16:47,466
And they reach the parts that
the warthogs fail to reach.
190
00:16:59,601 --> 00:17:01,034
When they finally finish,
191
00:17:01,101 --> 00:17:04,634
some very happy
customers are left behind.
192
00:17:08,568 --> 00:17:10,334
Who's next?
193
00:17:14,036 --> 00:17:16,435
They seem to think
that spy warthog
194
00:17:16,502 --> 00:17:18,532
is in need of
a full body treatment.
195
00:17:19,967 --> 00:17:21,601
They await the signal.
196
00:17:26,503 --> 00:17:28,702
He assumes
the grooming position.
197
00:17:33,336 --> 00:17:35,267
And the mongoose set to work,
198
00:17:35,336 --> 00:17:37,501
giving him
an intimate perspective
199
00:17:37,569 --> 00:17:40,568
of an extraordinary
partnership.
200
00:17:40,634 --> 00:17:44,333
Although his skin
must offer slim pickings.
201
00:17:55,635 --> 00:17:59,902
Warthogs aren't the only African
animal with unusual friends.
202
00:18:04,302 --> 00:18:05,802
Every lake and river
203
00:18:05,869 --> 00:18:08,635
has a resident
population of hippos.
204
00:18:08,702 --> 00:18:11,435
They too are social creatures,
205
00:18:11,503 --> 00:18:14,336
but they are also territorial.
206
00:18:21,968 --> 00:18:26,267
Spy hippo is going
where few others dare to go.
207
00:18:32,136 --> 00:18:33,837
He needs to be cautious.
208
00:18:46,769 --> 00:18:50,400
His subjects are
notoriously bad-tempered
209
00:18:50,469 --> 00:18:52,934
and they could be anywhere.
210
00:18:58,569 --> 00:19:01,601
It's never a good idea
to get on their wrong side.
211
00:19:09,435 --> 00:19:12,270
Spy hippo has been
given a warning.
212
00:19:15,734 --> 00:19:18,334
He must avoid
sudden movements.
213
00:19:20,869 --> 00:19:24,700
As he gets closer,
ear wiggling shows confidence.
214
00:19:30,202 --> 00:19:33,335
Facing one of Africa's
most dangerous animals,
215
00:19:33,402 --> 00:19:36,867
spy hippo
must hold his ground.
216
00:19:38,335 --> 00:19:42,434
The pod is made up of females
looked over by a single male.
217
00:19:43,669 --> 00:19:46,835
Fortunately,
females are less aggressive.
218
00:19:50,035 --> 00:19:53,968
Spy hippo is already capturing
some of the closest views
219
00:19:54,037 --> 00:19:55,800
that have ever been seen.
220
00:20:01,569 --> 00:20:05,034
But hippos spend much of their
time below the surface.
221
00:20:06,369 --> 00:20:08,268
As the hippos dive,
222
00:20:10,203 --> 00:20:12,003
so must spy hippo.
223
00:20:14,770 --> 00:20:16,935
He mimics their movements.
224
00:20:18,536 --> 00:20:22,534
Rather than swim,
hippos walk underwater.
225
00:20:28,535 --> 00:20:30,002
Through the murk,
226
00:20:30,069 --> 00:20:33,336
spy hippo glimpses
an extraordinary sight.
227
00:20:37,636 --> 00:20:41,234
Fish are shadowing
the hippos' every move.
228
00:20:41,302 --> 00:20:42,969
These are barbs.
229
00:20:44,403 --> 00:20:46,567
They usually feed
on the riverbed,
230
00:20:46,634 --> 00:20:49,868
but when the hippos appear,
they shoal around them.
231
00:20:55,502 --> 00:20:58,000
As spy hippo moves closer,
232
00:20:58,069 --> 00:20:59,435
it's clear that their skin
233
00:20:59,502 --> 00:21:01,601
is a maze of cuts
and scratches.
234
00:21:03,503 --> 00:21:06,436
These fight marks easily
become infected
235
00:21:06,503 --> 00:21:09,069
and parasites can also invade.
236
00:21:12,503 --> 00:21:14,600
This is where
the fish come in.
237
00:21:16,669 --> 00:21:19,769
Together they set up
an underwater clinic,
238
00:21:19,835 --> 00:21:22,968
with the hippos
as willing patients.
239
00:21:26,369 --> 00:21:29,669
The barbs may be
skin specialists,
240
00:21:29,735 --> 00:21:32,936
but they'll try a bit
of dental hygiene, too.
241
00:21:49,537 --> 00:21:51,835
After having
a full body treatment,
242
00:21:51,902 --> 00:21:54,601
the hippos seem
to enter a trance.
243
00:22:10,470 --> 00:22:12,170
Back in the Arctic,
244
00:22:12,235 --> 00:22:15,869
the lost wolf cub has been
waiting for three long days.
245
00:22:19,070 --> 00:22:22,003
Only spy cub
has been keeping watch.
246
00:22:25,836 --> 00:22:27,901
His howls
are becoming desperate.
247
00:22:37,670 --> 00:22:39,868
He is both hungry and tired.
248
00:22:39,937 --> 00:22:42,870
He now needs the pack
more than ever.
249
00:22:45,936 --> 00:22:48,935
Many miles away,
the pack is still searching,
250
00:22:49,002 --> 00:22:52,767
but the cub's calls are lost
in the vastness of the Tundra.
251
00:22:59,502 --> 00:23:01,101
The mother has
set her own course,
252
00:23:01,168 --> 00:23:04,068
sensing the urgency
of the danger he's in.
253
00:23:12,734 --> 00:23:15,302
But at least
her other cubs are safe.
254
00:23:21,601 --> 00:23:23,934
The cub's calls
can carry for over a mile,
255
00:23:24,003 --> 00:23:26,969
but only if the wind
is in the right direction.
256
00:23:30,635 --> 00:23:33,501
The mother can
only follow her instincts,
257
00:23:33,568 --> 00:23:35,500
she has so little to go on.
258
00:23:42,303 --> 00:23:43,668
In desperation,
259
00:23:43,735 --> 00:23:45,467
her cub leaves
his only protection
260
00:23:45,536 --> 00:23:47,534
to go searching for her.
261
00:23:52,336 --> 00:23:54,300
He howls into the canyon.
262
00:23:54,368 --> 00:23:56,568
It echoes his cries.
263
00:24:04,037 --> 00:24:06,737
It seems her cub
did the right thing.
264
00:24:33,003 --> 00:24:36,070
He heads off in the direction
of his mother's howls.
265
00:24:44,769 --> 00:24:48,136
It's taken three days
of searching,
266
00:24:48,202 --> 00:24:49,802
but she's found him.
267
00:24:54,770 --> 00:24:56,768
There's no time
for celebration,
268
00:24:56,837 --> 00:24:59,036
she must get him
back to the den.
269
00:25:13,835 --> 00:25:17,036
Now the whole pack
can welcome him back.
270
00:25:24,070 --> 00:25:26,101
The teamwork isn't over yet,
271
00:25:26,169 --> 00:25:28,937
as the cubs are still hungry.
272
00:25:30,669 --> 00:25:34,902
The father makes good
as he returns bearing gifts.
273
00:25:44,368 --> 00:25:45,901
As the cubs tuck in,
274
00:25:45,969 --> 00:25:49,068
he seems oblivious
to the trouble he's caused.
275
00:25:49,136 --> 00:25:51,402
But with everyone
working together,
276
00:25:51,469 --> 00:25:53,636
the precious cub was found.
277
00:25:56,970 --> 00:25:59,203
Pack life was
once thought to be
278
00:25:59,272 --> 00:26:01,235
about dominance
and submission,
279
00:26:01,304 --> 00:26:03,801
but what's actually
more important
280
00:26:03,868 --> 00:26:06,402
are their deep
bonds of friendship.
281
00:26:13,835 --> 00:26:16,300
Among our closest
animal relatives,
282
00:26:16,370 --> 00:26:18,736
friendships are
equally important.
283
00:26:18,803 --> 00:26:21,835
But they are also
far more political.
284
00:26:25,004 --> 00:26:26,170
In Senegal,
285
00:26:26,236 --> 00:26:28,935
spy bush baby is concealed
in a tree stump
286
00:26:29,002 --> 00:26:33,002
to film a group of chimpanzees
visiting a jungle water hole.
287
00:26:40,870 --> 00:26:43,303
They are the only chimps
to bathe like this
288
00:26:43,369 --> 00:26:47,067
and they have their version
of a members-only spa.
289
00:26:48,570 --> 00:26:51,802
Here, they get relief
from the oppressive heat,
290
00:26:51,869 --> 00:26:54,969
but it's also
a place to socialise,
291
00:26:55,037 --> 00:26:58,469
a chance for the youngsters
to play and make friends.
292
00:27:02,637 --> 00:27:05,837
They also admire
their reflections.
293
00:27:05,904 --> 00:27:08,036
Chimps are one
of the few animals
294
00:27:08,104 --> 00:27:09,803
that can recognise themselves.
295
00:27:14,736 --> 00:27:18,269
Who you are is important
in chimp society.
296
00:27:22,768 --> 00:27:25,102
And friendships forged
at this young age
297
00:27:25,170 --> 00:27:28,004
make all the difference
in later life.
298
00:27:28,070 --> 00:27:30,837
That's when
position really matters.
299
00:27:33,603 --> 00:27:37,269
Here, elders must be
treated with respect,
300
00:27:39,836 --> 00:27:42,502
and youngsters
must know their place.
301
00:27:45,135 --> 00:27:48,569
When the big males arrive,
family time is over.
302
00:27:50,569 --> 00:27:54,100
This is when friendships
get political.
303
00:27:59,704 --> 00:28:02,570
First in has choice
of the best spot,
304
00:28:02,637 --> 00:28:04,801
the deepest part of the pool.
305
00:28:07,270 --> 00:28:09,035
But not for long.
306
00:28:09,103 --> 00:28:11,802
A senior male pulls rank.
307
00:28:16,570 --> 00:28:19,170
Each new male
is aware of his position
308
00:28:19,237 --> 00:28:21,302
and where his friendships lie.
309
00:28:22,103 --> 00:28:24,236
These two don't get on,
310
00:28:24,303 --> 00:28:27,834
but this one's
a very good friend.
311
00:28:27,902 --> 00:28:31,237
So everyone shuffles around
depending on who they are
312
00:28:31,304 --> 00:28:33,004
and who they are friends with.
313
00:28:40,503 --> 00:28:43,903
The most important
likes to make an entrance...
314
00:28:46,635 --> 00:28:48,835
And claims the prime spot.
315
00:28:51,868 --> 00:28:54,568
Once places
are properly allocated,
316
00:28:54,636 --> 00:28:56,668
it's time for some
male grooming,
317
00:28:56,737 --> 00:29:00,004
a chance to confirm
friendships and alliances.
318
00:29:01,538 --> 00:29:02,771
These bonding moments
319
00:29:02,837 --> 00:29:05,703
reduce stress
and improve their health.
320
00:29:07,536 --> 00:29:10,735
Like humans,
chimps yawn sympathetically,
321
00:29:10,803 --> 00:29:12,966
a sign of closeness
and empathy
322
00:29:13,035 --> 00:29:14,603
among familiar friends.
323
00:29:17,869 --> 00:29:21,304
This is now strictly
a male-only spa,
324
00:29:21,371 --> 00:29:23,267
so mothers must
find other ways
325
00:29:23,336 --> 00:29:25,133
to entertain the kids.
326
00:29:32,304 --> 00:29:35,470
Or let them
entertain themselves.
327
00:29:39,770 --> 00:29:44,637
A five-year-old finds another
of the spy cameras,
328
00:29:44,704 --> 00:29:48,869
a filming device based on
the fruit of the baobab tree.
329
00:29:52,569 --> 00:29:55,569
Perfect for
an improvised ball game.
330
00:30:00,869 --> 00:30:04,203
But balls have
a habit of going astray.
331
00:30:08,572 --> 00:30:12,370
And where it's landed
is strictly out of bounds.
332
00:30:15,505 --> 00:30:18,603
It wouldn't be wise
to try to get it back.
333
00:30:21,970 --> 00:30:26,169
But it's giving spy baobab
a unique view of chimpanzees
334
00:30:26,238 --> 00:30:27,904
at their most relaxed.
335
00:30:34,837 --> 00:30:37,937
A time when they can
get rid of ticks or fleas.
336
00:30:48,104 --> 00:30:49,936
Or just chill out.
337
00:30:58,338 --> 00:31:00,136
With his ball out of play,
338
00:31:00,205 --> 00:31:02,770
the five-year-old
finds other things to do.
339
00:31:05,204 --> 00:31:06,736
But one brave female
340
00:31:06,803 --> 00:31:10,138
is prepared to risk joining
this male-exclusive club.
341
00:31:11,969 --> 00:31:17,069
She's rightly nervous, but a male
reaches out a hand of friendship.
342
00:31:17,137 --> 00:31:21,503
She's a high-ranking female and this
gives her special privileges...
343
00:31:24,671 --> 00:31:27,805
ones that also apply
to her baby.
344
00:31:31,902 --> 00:31:33,836
But the mother
is still cautious.
345
00:31:34,971 --> 00:31:36,802
Some males
aren't so tolerant.
346
00:31:40,138 --> 00:31:42,636
The mother retreats
but for her daughter,
347
00:31:42,703 --> 00:31:44,969
the water is
just too tempting.
348
00:31:48,972 --> 00:31:51,804
Her cheekiness
doesn't go unnoticed.
349
00:31:58,170 --> 00:32:00,035
But a kiss reassures her
350
00:32:01,270 --> 00:32:03,602
and confirms
her special status.
351
00:32:06,403 --> 00:32:10,034
This little chimp is already
indulged more than most youngsters
352
00:32:10,103 --> 00:32:12,636
and is likely to rise
to a high position.
353
00:32:16,170 --> 00:32:18,903
For the males
and their gentlemen's club,
354
00:32:18,970 --> 00:32:20,536
bath time is over.
355
00:32:30,770 --> 00:32:33,336
The others waste no time.
356
00:32:33,403 --> 00:32:35,369
As everyone
rejoins the pool party,
357
00:32:35,439 --> 00:32:37,837
friends can play once more.
358
00:32:41,504 --> 00:32:44,469
The five-year-old
finally gets his ball back
359
00:32:44,537 --> 00:32:46,669
and takes
an accidental selfie.
360
00:32:54,704 --> 00:32:58,701
Among chimps, friendships keep
the community together,
361
00:32:58,770 --> 00:33:04,036
and these exclusive baths have
become the hub of their social life.
362
00:33:09,638 --> 00:33:11,437
Back in the Kalahari,
363
00:33:11,505 --> 00:33:14,738
the meerkats have a far more
egalitarian view of friendship.
364
00:33:17,772 --> 00:33:20,838
And there is one friend who
now seems totally at home.
365
00:33:21,904 --> 00:33:24,204
Spy meerkat.
366
00:33:24,270 --> 00:33:28,101
She is filming the details
of life in the creche.
367
00:33:28,171 --> 00:33:33,238
Among meerkats, it is the
focus of their social life.
368
00:33:33,305 --> 00:33:37,404
Here, the babies learn to make
friends and discover who's who.
369
00:33:40,704 --> 00:33:45,004
As childminders change all the time,
the babies soon meet everyone.
370
00:33:53,502 --> 00:33:55,071
As the youngsters
groom each other,
371
00:33:55,138 --> 00:33:57,703
they establish their own
bonds of friendship.
372
00:34:01,637 --> 00:34:04,302
They also learn the secrets
of how to get along.
373
00:34:05,870 --> 00:34:08,169
The childminders
also clean out the den
374
00:34:08,239 --> 00:34:11,936
and even make decisions on
when the pups should be moved.
375
00:34:12,002 --> 00:34:15,868
This happens when nest parasites
become just too much.
376
00:34:16,771 --> 00:34:18,870
Moving day is a big event
377
00:34:18,937 --> 00:34:21,036
and the process
must happen quickly.
378
00:34:22,803 --> 00:34:27,536
To stay with them,
spy meerkat needs some help.
379
00:34:32,439 --> 00:34:35,404
He hitches a ride on a mobile
termite mound,
380
00:34:35,470 --> 00:34:38,070
complete with its own
stabilised camera.
381
00:34:50,605 --> 00:34:52,737
With so many pups to care for,
382
00:34:52,804 --> 00:34:55,304
it's easy for one
to be left behind.
383
00:34:57,370 --> 00:34:59,168
He's the smallest
of the litter
384
00:34:59,238 --> 00:35:01,870
and he's hardly ventured
from the den before.
385
00:35:10,936 --> 00:35:13,870
He faces plenty
of unexpected pitfalls.
386
00:35:17,837 --> 00:35:21,736
Spy meerkat is following
the rest of the gang.
387
00:35:21,804 --> 00:35:25,637
And these pups move confidently
with the adults in charge.
388
00:35:33,105 --> 00:35:35,837
In the rush,
they didn't check the numbers.
389
00:35:39,405 --> 00:35:43,303
But with the pups out in the
open, it's wisest to keep going.
390
00:35:51,004 --> 00:35:53,970
The little pup is now
even further behind.
391
00:35:55,104 --> 00:35:58,372
It's a long trek
for such tiny legs.
392
00:36:05,271 --> 00:36:07,872
And the heat
is taking its toll.
393
00:36:11,672 --> 00:36:14,705
When spy meerkat arrives
at the new den site,
394
00:36:14,771 --> 00:36:16,569
everyone is
already assembling.
395
00:36:21,037 --> 00:36:24,104
The cubs are introduced
to their new accommodation.
396
00:36:31,637 --> 00:36:33,870
Now they have time
for a headcount.
397
00:36:35,437 --> 00:36:37,736
They realise
one has been left behind.
398
00:36:39,204 --> 00:36:42,670
All alone, he has no idea
which way to go.
399
00:37:19,636 --> 00:37:22,371
His childminder
hasn't let him down.
400
00:37:31,937 --> 00:37:34,870
Ultimately, everyone must be
accounted for.
401
00:37:40,970 --> 00:37:45,604
Meerkat society works because
everyone cares for everyone else.
402
00:37:45,672 --> 00:37:48,570
It's an ethos that begins
when they are just pups.
403
00:37:50,636 --> 00:37:53,837
Those out foraging
soon track down the new den.
404
00:37:58,438 --> 00:38:00,837
The mother is reunited
with her babies
405
00:38:00,904 --> 00:38:03,669
and her helpers
can rest at last,
406
00:38:03,738 --> 00:38:06,639
having done their best
for the good of the colony.
407
00:38:17,371 --> 00:38:22,071
The need to protect young has given
rise to unlikely friendships.
408
00:38:23,504 --> 00:38:25,970
Murchison Falls in Uganda.
409
00:38:28,503 --> 00:38:31,337
This is spy crocodile.
410
00:38:37,203 --> 00:38:38,702
Like a real croc,
411
00:38:38,769 --> 00:38:42,037
he's just as manoeuvrable
in water as he is on land.
412
00:38:48,905 --> 00:38:50,504
He needs to be.
413
00:38:50,571 --> 00:38:54,038
Where he's going is difficult
and dangerous to reach.
414
00:39:00,439 --> 00:39:02,570
And in this special place,
415
00:39:02,639 --> 00:39:06,904
spy crocodile is going to film
a very brave little bird.
416
00:39:14,371 --> 00:39:17,004
These are water dikkop,
417
00:39:17,071 --> 00:39:18,803
a type of stone-curlew.
418
00:39:20,370 --> 00:39:24,703
They may be small, but they
like to live life dangerously.
419
00:39:29,705 --> 00:39:32,537
Their nearest neighbour
is a crocodile,
420
00:39:32,604 --> 00:39:36,005
and their nest
is right next to hers.
421
00:39:38,139 --> 00:39:41,172
Few would dare to shepherd
a crocodile,
422
00:39:41,238 --> 00:39:43,937
but the fearless dikkop
protects her nest
423
00:39:44,006 --> 00:39:45,838
by marshalling the croc away.
424
00:39:51,471 --> 00:39:55,970
The dikkop only gives up when the
croc is safely at her own nest.
425
00:39:58,236 --> 00:40:02,870
Filming the action around the nest
are some spy crocodile hatchlings...
426
00:40:05,036 --> 00:40:07,704
and the crocodile
guards them as her own.
427
00:40:12,538 --> 00:40:16,002
It seems insane for the
dikkops to nest so close,
428
00:40:16,071 --> 00:40:19,005
especially when
a second croc arrives.
429
00:40:22,871 --> 00:40:26,272
Nesting crocs
are intensely territorial.
430
00:40:31,704 --> 00:40:34,271
This is too much
for any dikkop to handle.
431
00:40:45,005 --> 00:40:47,337
But the rival
is quickly dispatched.
432
00:40:53,370 --> 00:40:54,804
The dikkop settle,
433
00:40:54,871 --> 00:40:58,402
a moment of calm
as the croc guards her nest.
434
00:41:04,903 --> 00:41:06,835
But it doesn't last.
435
00:41:06,904 --> 00:41:10,502
In the heat of the day,
the croc heads for water.
436
00:41:13,604 --> 00:41:17,005
It's a moment not lost
on this monitor lizard.
437
00:41:24,037 --> 00:41:26,702
Nile monitors
eat both crocodile eggs
438
00:41:26,771 --> 00:41:28,472
and those of the dikkop.
439
00:41:32,937 --> 00:41:37,404
But it's the croc's unprotected
nest that interests him now.
440
00:41:41,270 --> 00:41:43,436
Except for the spy hatchlings,
441
00:41:43,506 --> 00:41:45,537
the monitor has the place
to himself.
442
00:41:50,839 --> 00:41:53,438
He's soon digging
for the buried treasure.
443
00:42:00,771 --> 00:42:03,538
And gets a taste
of a spy hatchling.
444
00:42:07,505 --> 00:42:09,771
But the real eggs
are what he's come for.
445
00:42:11,673 --> 00:42:14,006
The dikkop steps
into action again.
446
00:42:15,705 --> 00:42:19,604
If she can stand up to a croc,
a four-foot lizard is nothing.
447
00:42:25,505 --> 00:42:27,871
She even tweaks
the dragon's tail.
448
00:42:30,238 --> 00:42:33,505
Dikkops must be among
the pluckiest birds on Earth.
449
00:42:37,605 --> 00:42:40,272
The male at the nest
joins the battle.
450
00:42:41,405 --> 00:42:43,971
They are a formidable team.
451
00:42:44,040 --> 00:42:47,904
It's a risky strategy, as the
dikkop's nest is now exposed...
452
00:42:52,104 --> 00:42:54,637
and the monitor
won't give up easily.
453
00:42:56,038 --> 00:42:58,537
So the mother
returns to her nest.
454
00:43:05,804 --> 00:43:09,502
With both bird and egg thief
holding their ground,
455
00:43:09,571 --> 00:43:10,971
it's a stand-off.
456
00:43:14,739 --> 00:43:17,103
Time to call
for reinforcements.
457
00:43:19,704 --> 00:43:22,839
And the crocodile
hears the call to arms.
458
00:43:33,705 --> 00:43:35,970
The monitor is totally
outclassed.
459
00:43:38,772 --> 00:43:41,772
And this is why
it was worth nesting here.
460
00:43:45,805 --> 00:43:48,037
They may be friends
of convenience,
461
00:43:48,106 --> 00:43:49,706
but here most crocodile nests
462
00:43:49,771 --> 00:43:52,839
have their own resident pair
of fearless dikkops.
463
00:43:58,372 --> 00:43:59,905
In North America,
464
00:43:59,972 --> 00:44:03,373
prairie dogs also have
some unexpected neighbours.
465
00:44:05,805 --> 00:44:09,871
Spy prairie dog discovers
who these squatters are.
466
00:44:12,405 --> 00:44:14,271
They are burrowing owls.
467
00:44:16,605 --> 00:44:19,872
They make good use
of any available free housing.
468
00:44:22,440 --> 00:44:24,804
They may be uninvited guests,
469
00:44:24,871 --> 00:44:27,270
but they still make
the best of neighbours.
470
00:44:28,439 --> 00:44:30,636
The owls hunt mainly insects,
471
00:44:30,705 --> 00:44:32,836
so they are no risk
to the prairie dogs
472
00:44:32,906 --> 00:44:36,705
and they also help
watch for predators.
473
00:44:36,772 --> 00:44:40,037
In turn, the owls use the
prairie dogs' alarm system,
474
00:44:40,104 --> 00:44:42,937
so their close relationship
works for both of them.
475
00:44:44,137 --> 00:44:45,839
In the pupping season,
476
00:44:45,906 --> 00:44:49,306
the prairie dogs are on high
alert, watching for danger.
477
00:44:53,539 --> 00:44:56,672
And rattlesnakes
are one of the enemy.
478
00:45:05,505 --> 00:45:08,538
But this snake is another
spy creature.
479
00:45:11,439 --> 00:45:14,370
The prairie dog
sends out an alert.
480
00:45:14,439 --> 00:45:16,505
He has a special word
for "snake".
481
00:45:22,339 --> 00:45:23,673
But rather than panic,
482
00:45:23,738 --> 00:45:25,870
the prairie dogs and owls
stay where they are.
483
00:45:28,205 --> 00:45:31,804
Theirs is a very measured
response based on how dangerous
484
00:45:31,871 --> 00:45:33,437
the threat really is.
485
00:45:36,705 --> 00:45:40,238
And as spy snake shows
no sign of moving closer,
486
00:45:40,305 --> 00:45:42,037
they simply keep an eye on it.
487
00:45:44,438 --> 00:45:46,905
There are plenty of other
threats to be worried about.
488
00:45:53,973 --> 00:45:55,006
A coyote.
489
00:45:59,539 --> 00:46:01,371
They have their own name
for it, too.
490
00:46:02,737 --> 00:46:05,371
They shout it out
to alert the whole colony.
491
00:46:10,071 --> 00:46:13,604
But like the snake alarm, it
doesn't create immediate panic.
492
00:46:18,006 --> 00:46:21,738
Each chirp lasts
just one tenth of a second,
493
00:46:21,805 --> 00:46:23,837
but it's packed
with subtle meaning
494
00:46:23,905 --> 00:46:26,672
so that everyone can know
the nature of any threat.
495
00:46:28,373 --> 00:46:30,205
In fact,
496
00:46:30,271 --> 00:46:34,336
prairie dogs have the most complex
animal language ever discovered.
497
00:46:34,405 --> 00:46:36,904
Nouns define
the type of predator.
498
00:46:40,605 --> 00:46:43,839
Adjectives describe
if the threat is near or far.
499
00:46:48,172 --> 00:46:51,372
And adverbs explain
how fast it's moving.
500
00:46:53,071 --> 00:46:56,536
The chirps for a walking
coyote are further apart
501
00:46:56,606 --> 00:46:58,537
and cause little reaction.
502
00:47:01,073 --> 00:47:03,571
The quicker chirps
for a running coyote
503
00:47:03,638 --> 00:47:05,403
demand immediate attention.
504
00:47:06,972 --> 00:47:08,672
Now it's time to panic.
505
00:47:17,872 --> 00:47:21,404
The coyotes head off
for an easier meal.
506
00:47:25,040 --> 00:47:28,604
When they are gone, the prairie
dogs sound the all clear.
507
00:47:35,105 --> 00:47:38,637
Their language allows prairie
dogs to stay above ground
508
00:47:38,706 --> 00:47:42,039
until the last
possible moment,
509
00:47:42,106 --> 00:47:45,507
while the owls just have to
watch what the prairie dogs do.
510
00:47:47,306 --> 00:47:51,104
Time for a traditional
celebration, the jump-yip.
511
00:48:27,306 --> 00:48:29,470
Friendships help guard
against danger,
512
00:48:29,538 --> 00:48:33,537
but sometimes you have to make
friends with the enemy themselves.
513
00:48:39,638 --> 00:48:43,804
The langurs of India are among
the most agile of all monkeys.
514
00:48:53,038 --> 00:48:56,005
Spy monkey is also capturing
the quiet moments,
515
00:48:56,074 --> 00:48:57,972
when friendships
are really made.
516
00:49:06,971 --> 00:49:09,471
Grooming is used
to calm tensions,
517
00:49:09,539 --> 00:49:12,438
build trust
and cement relationships.
518
00:49:17,872 --> 00:49:20,773
They even try to make friends
with spy monkey.
519
00:49:27,872 --> 00:49:30,437
Stray dogs live
alongside the langurs,
520
00:49:30,506 --> 00:49:33,306
scavenging on food that people
leave for the monkeys.
521
00:49:35,739 --> 00:49:38,340
They aren't the friendliest
of neighbours.
522
00:49:39,872 --> 00:49:42,303
They see monkeys
as competition for food
523
00:49:42,372 --> 00:49:45,406
and will even kill a monkey if
it gets on their wrong side.
524
00:49:48,007 --> 00:49:49,440
So for their own safety,
525
00:49:49,507 --> 00:49:51,439
the langurs try
to make friends.
526
00:49:56,575 --> 00:49:59,006
But the dogs
aren't easily won over.
527
00:50:06,273 --> 00:50:08,070
To ingratiate themselves,
528
00:50:08,139 --> 00:50:11,138
the monkeys use the same technique
they use with each other.
529
00:50:12,638 --> 00:50:15,404
But grooming a dog
is like playing with fire.
530
00:50:17,039 --> 00:50:20,039
Especially when you don't
understand the body language.
531
00:50:21,939 --> 00:50:26,104
But if they can make friends,
they are less likely to get hurt.
532
00:50:26,171 --> 00:50:29,337
Here, it's a matter of keeping
your friends close
533
00:50:29,404 --> 00:50:31,071
and your enemies closer.
534
00:50:32,505 --> 00:50:35,972
Fortunately, most dogs
just want to be loved,
535
00:50:36,041 --> 00:50:39,773
and they soon succumb to the
monkeys' unsolicited advances.
536
00:50:40,873 --> 00:50:43,438
Grooming brings
other rewards,
537
00:50:43,505 --> 00:50:46,738
a tick makes a juicy treat.
538
00:50:46,805 --> 00:50:48,903
They even start
taking liberties.
539
00:50:51,805 --> 00:50:54,837
This personal valet service
diffuses aggression
540
00:50:54,906 --> 00:50:57,006
and helps everyone
to get along.
541
00:50:59,340 --> 00:51:02,338
For a puppy,
there's a different reward,
542
00:51:02,405 --> 00:51:04,639
monkeys make
the perfect playmates.
543
00:51:41,140 --> 00:51:44,474
Like the langurs, intelligent
animals have subtle
544
00:51:44,539 --> 00:51:46,839
and sometimes
manipulative friendships.
545
00:51:49,439 --> 00:51:50,839
And those of chimps
546
00:51:50,906 --> 00:51:53,740
show the greatest connections
with our own lives.
547
00:51:56,106 --> 00:51:57,538
Filming the Senegal chimps
548
00:51:57,606 --> 00:52:00,072
requires an array
of spy cameras.
549
00:52:02,439 --> 00:52:04,371
As well as spy bushbaby,
550
00:52:04,440 --> 00:52:06,704
spy tortoise is also here.
551
00:52:13,540 --> 00:52:17,772
And spy tree stump
offers discreet coverage.
552
00:52:17,838 --> 00:52:21,703
There can be ten different cameras
deployed at any one time.
553
00:52:23,339 --> 00:52:26,405
A chimp hears something that
suddenly changes the mood.
554
00:52:27,974 --> 00:52:29,674
It's the sound of prey.
555
00:52:31,174 --> 00:52:32,773
They move into hunting mode.
556
00:52:47,974 --> 00:52:51,537
This is when rivalries and
position are put to one side.
557
00:52:54,873 --> 00:52:57,406
Everyone is now
working together.
558
00:53:01,472 --> 00:53:05,606
It's their bonds of friendship
that allow them to hunt as a team.
559
00:53:09,274 --> 00:53:10,874
They glimpse their quarry.
560
00:53:16,338 --> 00:53:18,571
It's a large troop of baboons.
561
00:53:22,807 --> 00:53:26,273
They plan to encircle them
and take them by surprise.
562
00:53:27,440 --> 00:53:29,237
They set off
in different directions,
563
00:53:29,306 --> 00:53:31,008
moving silently as they go.
564
00:53:35,506 --> 00:53:37,804
Each takes up
a different position.
565
00:53:45,541 --> 00:53:47,973
Standing on two legs
gives a better view.
566
00:53:57,639 --> 00:54:00,506
When everyone's in place,
they stop.
567
00:54:03,707 --> 00:54:05,471
One flushes the baboons.
568
00:54:14,073 --> 00:54:16,005
But their escape is blocked.
569
00:54:18,674 --> 00:54:20,373
It's just as they planned.
570
00:54:23,572 --> 00:54:24,773
There's no way out.
571
00:54:38,340 --> 00:54:40,338
To the victor the prize...
572
00:54:41,472 --> 00:54:42,940
or so they say.
573
00:54:44,640 --> 00:54:46,471
But it's not that simple.
574
00:54:52,173 --> 00:54:54,639
For this youngster,
it's all too tempting.
575
00:54:58,372 --> 00:55:00,471
He sneaks down
to beg for a bite.
576
00:55:01,706 --> 00:55:03,637
This is not the etiquette.
577
00:55:03,706 --> 00:55:07,171
He must learn
that the victor eats first.
578
00:55:07,240 --> 00:55:10,406
His mother saves him from
further social embarrassment,
579
00:55:10,473 --> 00:55:11,840
and perhaps worse.
580
00:55:18,007 --> 00:55:22,040
Then a ritual
with huge significance begins.
581
00:55:23,673 --> 00:55:26,806
The successful hunter
starts to share.
582
00:55:30,040 --> 00:55:32,773
The giving of meat
reinforces their friendships,
583
00:55:32,840 --> 00:55:35,840
meaning everyone will
contribute in future hunts.
584
00:55:39,406 --> 00:55:45,171
Such generosity releases the brain's
feel-good hormone oxytocin,
585
00:55:45,240 --> 00:55:48,704
making everyone feel content.
586
00:55:48,773 --> 00:55:51,473
One chimp is tempted
to jump the queue.
587
00:55:53,272 --> 00:55:57,306
But only close friends get
away with taking liberties.
588
00:56:00,773 --> 00:56:04,338
Everyone ultimately
gets at least a morsel.
589
00:56:06,872 --> 00:56:11,338
Even the baby chimp,
who was rather too eager.
590
00:56:17,874 --> 00:56:21,840
The friendships, cooperation
and sharing that chimps show
591
00:56:21,907 --> 00:56:26,441
is the foundation on which all
complex societies are laid.
592
00:56:35,908 --> 00:56:37,440
Now that
everyone's feeling good,
593
00:56:37,507 --> 00:56:41,039
it's a chance to play
and relax once more.
594
00:56:41,108 --> 00:56:43,907
There's nothing better
than hanging out with friends.
595
00:56:50,040 --> 00:56:54,972
In the animal world, friendships
lie at the heart of the community.
596
00:56:57,140 --> 00:56:58,773
From friends among equals
597
00:56:59,741 --> 00:57:01,840
to friendships in adversity.
598
00:57:03,108 --> 00:57:05,574
From friends of convenience
599
00:57:05,641 --> 00:57:08,939
and those for
self-preservation.
600
00:57:09,006 --> 00:57:11,606
These many different
animal relationships
601
00:57:11,673 --> 00:57:14,906
mirror the complexities
of our own.
602
00:57:19,773 --> 00:57:22,373
Next time,
our team of spy creatures
603
00:57:22,439 --> 00:57:24,072
investigates how and why
604
00:57:24,142 --> 00:57:28,607
animals misbehave, sometimes
in spectacular fashion.
