1
00:00:02,000 --> 00:00:05,640
The world is full
of extraordinary animals.
2
00:00:07,800 --> 00:00:10,920
But how well
do we really understand them?
3
00:00:11,880 --> 00:00:14,840
How do they really think and feel?
4
00:00:15,800 --> 00:00:20,160
To find out, a team of
spy creatures is going undercover.
5
00:00:21,440 --> 00:00:23,840
They not only look like
part of the family,
6
00:00:23,840 --> 00:00:26,720
they behave like them, too.
7
00:00:29,040 --> 00:00:31,400
Armed with the latest
camera technology...
8
00:00:33,000 --> 00:00:34,680
..they are going
to travel the globe...
9
00:00:36,040 --> 00:00:39,960
..to understand the true nature
of the animals they meet
10
00:00:39,960 --> 00:00:43,440
and reveal how intelligent
they really are...
11
00:00:46,280 --> 00:00:48,600
..how badly behaved they can be...
12
00:00:51,320 --> 00:00:53,920
...how important
friendship is to them...
13
00:00:55,440 --> 00:00:57,240
..and if it's possible
14
00:00:57,240 --> 00:00:59,480
that they can truly love each other.
15
00:00:59,480 --> 00:01:03,880
What they discover will change
our perception of animals forever.
16
00:01:07,240 --> 00:01:11,840
Perhaps they are more like us
than we ever believed possible.
17
00:01:18,840 --> 00:01:19,960
SCREECHING
18
00:01:23,120 --> 00:01:25,920
Animals live complex lives,
19
00:01:25,920 --> 00:01:28,480
but how sophisticated
are their emotions?
20
00:01:32,920 --> 00:01:37,240
On the African savanna lives
one of the world's most intelligent
21
00:01:37,240 --> 00:01:39,600
and family-focused animals -
22
00:01:39,600 --> 00:01:40,800
the wild dog.
23
00:01:43,400 --> 00:01:47,080
In this pack, all the puppies
belong to just one mother,
24
00:01:47,080 --> 00:01:48,600
but are showered with affection
25
00:01:48,600 --> 00:01:51,720
by every member
of the extended family.
26
00:01:55,760 --> 00:02:00,040
When the adults go hunting,
a new pup makes an appearance.
27
00:02:02,400 --> 00:02:05,400
This is spy pup.
The only giveaway
28
00:02:05,400 --> 00:02:07,960
is the camera in his eye.
29
00:02:10,480 --> 00:02:11,720
YELPING
30
00:02:11,720 --> 00:02:15,000
He is here to film
the emotional dynamics of pack life,
31
00:02:15,000 --> 00:02:18,840
but first, he must
be accepted by the pups.
32
00:02:20,240 --> 00:02:22,560
They could easily
rip him to pieces...
33
00:02:25,560 --> 00:02:30,000
..so he mimics their body language,
to make them feel at ease.
34
00:02:33,480 --> 00:02:35,720
He uses the play bow.
35
00:02:35,720 --> 00:02:38,480
It's a universal invitation
to have fun.
36
00:02:48,080 --> 00:02:49,600
He's won them over,
37
00:02:49,600 --> 00:02:52,560
despite his slightly-strange smell.
38
00:02:57,840 --> 00:03:01,840
The adults, however,
may be harder to convince.
39
00:03:07,480 --> 00:03:11,240
So, he makes a submissive gesture
and wags his tail.
40
00:03:15,960 --> 00:03:17,440
GROWLING
41
00:03:26,880 --> 00:03:31,200
Now accepted, he soon gains
the most intimate view
42
00:03:31,200 --> 00:03:33,000
of wild dogs ever seen.
43
00:03:46,760 --> 00:03:50,640
The pups beg for food
by licking the adults' mouths.
44
00:03:50,640 --> 00:03:53,800
Fresh meat caught just for them.
45
00:03:59,960 --> 00:04:02,560
With survival depending on teamwork,
46
00:04:02,560 --> 00:04:05,520
affection strengthens family ties.
47
00:04:08,720 --> 00:04:13,160
Unfortunately, it's not just
spy pup that's watching them.
48
00:04:16,640 --> 00:04:18,040
BARKING
49
00:04:21,480 --> 00:04:25,640
The strength of their love
is about to be tested.
50
00:04:34,120 --> 00:04:37,080
Lions regard wild dogs as rivals.
51
00:04:45,160 --> 00:04:47,440
She'll kill the pups, if she can.
52
00:05:00,600 --> 00:05:04,080
Spy pup can only
lay low and observe.
53
00:05:19,080 --> 00:05:21,640
The lioness picks up
the smell of the den.
54
00:05:28,120 --> 00:05:30,160
The dogs try
to divert her attention.
55
00:05:30,160 --> 00:05:31,760
WHINNYING
56
00:05:34,120 --> 00:05:37,800
But with pups in her sight,
she won't be easily distracted.
57
00:05:42,640 --> 00:05:45,400
The pack keeps up the diversion.
58
00:05:47,560 --> 00:05:51,160
But it's the desperate mother
who decides to risk all...
59
00:05:56,240 --> 00:05:59,560
..goading the lioness to attack her.
60
00:06:18,160 --> 00:06:20,280
Over and over, she teases the lion,
61
00:06:20,280 --> 00:06:22,320
while the pack provides backup.
62
00:06:34,240 --> 00:06:37,720
After 40 minutes
of relentless pressure,
63
00:06:37,720 --> 00:06:40,600
the exhausted lioness
accepts defeat.
64
00:06:43,880 --> 00:06:48,760
Spy pup had a ringside view
of this extraordinary encounter.
65
00:06:48,760 --> 00:06:53,560
And in the aftermath, the pups
are reunited with their mother.
66
00:06:57,280 --> 00:07:00,400
Although family affection runs deep,
67
00:07:00,400 --> 00:07:03,240
nothing competes
with the love of a mother.
68
00:07:08,320 --> 00:07:12,920
After the lion's visit,
it's her that cleans the den.
69
00:07:12,920 --> 00:07:16,520
For her pups, it's a chance
to enjoy the dust bath.
70
00:07:24,760 --> 00:07:27,000
Even spy pup joins the fun.
71
00:07:48,200 --> 00:07:50,920
A mother's love is so fundamental,
72
00:07:50,920 --> 00:07:54,800
could it be found in a relic
from a prehistoric age?
73
00:08:00,600 --> 00:08:03,320
In Uganda, this Nile crocodile
74
00:08:03,320 --> 00:08:06,680
is coming ashore
for a very important event.
75
00:08:08,120 --> 00:08:12,240
Her babies are about to hatch.
76
00:08:21,080 --> 00:08:25,360
Sharing her nest
are some very special hatchlings.
77
00:08:27,560 --> 00:08:32,200
Ones with cameras in their eyes.
They are here to record
78
00:08:32,200 --> 00:08:35,440
the relationship between
a mother crocodile and her young.
79
00:08:40,480 --> 00:08:43,520
The spy hatchlings
have been filming her for days,
80
00:08:43,520 --> 00:08:46,240
as she waits for
her real young to arrive.
81
00:08:47,160 --> 00:08:48,880
CAWING
82
00:08:49,880 --> 00:08:52,920
The calls of her babies
synchronise their hatching,
83
00:08:52,920 --> 00:08:56,560
encouraging the whole brood
to emerge at once.
84
00:09:02,760 --> 00:09:05,320
They are also cries
for her attention.
85
00:09:11,280 --> 00:09:12,680
For three long months,
86
00:09:12,680 --> 00:09:14,960
she protected her eggs
day and night,
87
00:09:14,960 --> 00:09:16,680
as she waited for this moment.
88
00:09:26,680 --> 00:09:29,920
Now, she meets her babies
for the first time.
89
00:09:40,960 --> 00:09:42,720
They are delicate and vulnerable.
90
00:09:44,880 --> 00:09:47,440
GROWLING
91
00:09:48,560 --> 00:09:53,200
But they are not safe here.
She must get them to water.
92
00:09:54,200 --> 00:09:56,640
Her solution is extraordinary.
93
00:10:07,560 --> 00:10:11,440
Despite having
the most powerful bite in nature,
94
00:10:11,440 --> 00:10:13,480
she carefully
gathers them in a throat pouch,
95
00:10:13,480 --> 00:10:15,800
beneath a stockade of deadly teeth.
96
00:10:17,440 --> 00:10:20,920
She is as gentle
as a croc could ever be.
97
00:10:34,600 --> 00:10:38,960
Safe in her care,
tails dangling between her teeth,
98
00:10:38,960 --> 00:10:40,720
she takes them to water.
99
00:10:57,360 --> 00:10:59,960
She won't enjoy
her babies' company for long.
100
00:11:03,200 --> 00:11:06,000
Crocodiles can have 80 hatchlings...
101
00:11:07,240 --> 00:11:10,560
..and another batch is crying
for her attention.
102
00:11:10,560 --> 00:11:12,520
CAWING
103
00:11:20,360 --> 00:11:22,240
She won't leave any behind.
104
00:11:24,600 --> 00:11:27,120
Even spy hatchling.
105
00:11:59,320 --> 00:12:03,880
Safe in her cavernous mouth,
all survive unscathed.
106
00:12:08,840 --> 00:12:11,400
And spy hatchling is still filming.
107
00:12:17,840 --> 00:12:19,800
They still need her protection.
108
00:12:19,800 --> 00:12:23,200
Even in the water,
just one in ten survive...
109
00:12:24,840 --> 00:12:27,680
..for danger is everywhere.
110
00:12:30,080 --> 00:12:31,880
A grey heron.
111
00:12:34,040 --> 00:12:36,520
He has the pick of the bunch.
112
00:13:07,720 --> 00:13:11,920
Crocodiles have changed little
since the age of the dinosaurs,
113
00:13:11,920 --> 00:13:15,160
but their maternal care
is anything but primitive.
114
00:13:17,360 --> 00:13:21,240
She'll protect her babies
for the next two months.
115
00:13:24,640 --> 00:13:28,200
Such care becomes stronger
when whole families are involved.
116
00:13:33,040 --> 00:13:36,640
African elephants show a much
more developed sense of love.
117
00:13:40,280 --> 00:13:43,840
Their extended family
is made up of related females,
118
00:13:43,840 --> 00:13:46,320
led by a wise old matriarch.
119
00:13:46,320 --> 00:13:49,360
She holds the wisdom
of the generations
120
00:13:49,360 --> 00:13:52,080
and this needs
to be passed on to all.
121
00:13:55,400 --> 00:13:59,040
To infiltrate the herd,
a new spy creature is needed.
122
00:14:00,360 --> 00:14:03,120
One based on a bird
that lives among them.
123
00:14:05,800 --> 00:14:10,480
This is spy egret,
complete with a filming eye.
124
00:14:12,280 --> 00:14:16,400
The first challenge will be
surviving the initial encounter.
125
00:14:20,280 --> 00:14:22,720
It could be a brief assignment.
126
00:14:22,720 --> 00:14:24,840
CAWING
127
00:14:24,840 --> 00:14:28,280
He is facing 40 tonnes
of unstoppable herd.
128
00:14:48,640 --> 00:14:50,600
His first test over,
129
00:14:50,600 --> 00:14:53,160
it's now down to business.
130
00:14:55,160 --> 00:14:59,080
As well as spy egret, there are
other cameras covering the action.
131
00:15:01,800 --> 00:15:07,160
Spy tortoise can, quite literally,
get under the elephants' feet.
132
00:15:29,160 --> 00:15:32,760
The cameras soon capture
something remarkable.
133
00:15:39,000 --> 00:15:42,640
A vulnerable new arrival,
less than an hour old.
134
00:15:46,080 --> 00:15:49,000
His mother must help
her new-born to his feet.
135
00:15:55,520 --> 00:15:59,320
It's the start of the most
important relationship of his life.
136
00:16:09,760 --> 00:16:12,240
His first steps are a challenge.
137
00:16:31,000 --> 00:16:34,960
The bond between them will be
complete when he finally suckles.
138
00:16:37,360 --> 00:16:39,200
Easier said than done.
139
00:16:43,600 --> 00:16:46,080
His mother
gently guides him to the spot.
140
00:16:52,520 --> 00:16:54,560
It's time to meet the relatives.
141
00:17:05,520 --> 00:17:07,240
It's a big occasion.
142
00:17:07,240 --> 00:17:10,880
Each member of the family
wants to introduce themselves.
143
00:17:14,760 --> 00:17:18,480
They will all play a role
helping him grow up.
144
00:17:28,880 --> 00:17:32,000
For now,
the attention is overwhelming.
145
00:17:47,040 --> 00:17:50,160
But in the coming years,
he'll learn all he needs to know
146
00:17:50,160 --> 00:17:53,440
for his survival
from these loving females.
147
00:18:01,000 --> 00:18:04,560
The babies of some animals
have to find their place
148
00:18:04,560 --> 00:18:06,680
in even larger animal families.
149
00:18:12,680 --> 00:18:14,520
This temple in Rajasthan
150
00:18:14,520 --> 00:18:18,880
is home to a troop
of 120 Indian languors,
151
00:18:18,880 --> 00:18:21,600
made up of related females
and their offspring.
152
00:18:23,000 --> 00:18:27,960
They are the most gentle and
affectionate monkeys in the world.
153
00:18:27,960 --> 00:18:32,200
It's a sisterhood with
an unusual system of childcare.
154
00:18:36,960 --> 00:18:39,920
To see how this works in practice,
155
00:18:39,920 --> 00:18:43,480
a spy baby monkey
is joining the family -
156
00:18:43,480 --> 00:18:47,360
complete with camera eye
and a range of life-like movements.
157
00:18:47,360 --> 00:18:52,720
The plan is to blend
subtly into the crowd.
158
00:18:54,200 --> 00:18:57,280
But the monkeys have other ideas.
159
00:18:59,880 --> 00:19:02,040
They are more
than a little suspicious
160
00:19:02,040 --> 00:19:04,360
of the stranger in their midst.
161
00:19:09,200 --> 00:19:11,040
She's creating such a stir,
162
00:19:11,040 --> 00:19:14,120
every monkey in the neighbourhood
pays her a visit.
163
00:19:17,000 --> 00:19:21,000
Her camera reveals
the extraordinary athletic prowess
164
00:19:21,000 --> 00:19:22,960
of these lively monkeys.
165
00:20:13,120 --> 00:20:15,080
To escape the pandemonium,
166
00:20:15,080 --> 00:20:17,600
the mother has set up
a baby and toddler group
167
00:20:17,600 --> 00:20:19,720
in a quiet part of the temple.
168
00:20:20,760 --> 00:20:24,520
But looking after baby
is a full-time occupation.
169
00:20:24,520 --> 00:20:28,160
So, once they are three weeks old,
if Mum wants a break,
170
00:20:28,160 --> 00:20:32,920
she has a solution -
employ a teenage baby-sitter.
171
00:20:34,600 --> 00:20:37,920
As these young females
develop feelings of love and care,
172
00:20:37,920 --> 00:20:40,320
they just want to hold a baby.
173
00:20:42,080 --> 00:20:45,600
It's an arrangement
that gives the mums a break.
174
00:20:47,600 --> 00:20:49,840
A chance to be pampered and groomed.
175
00:20:53,280 --> 00:20:55,920
She may have a designated
baby-sitter, but here,
176
00:20:55,920 --> 00:20:58,480
every young female
wants to play mum.
177
00:21:11,760 --> 00:21:13,720
When everyone's had a go,
178
00:21:13,720 --> 00:21:16,520
there's always one
left holding the baby.
179
00:21:16,520 --> 00:21:19,040
It's a serious responsibility,
180
00:21:19,040 --> 00:21:21,600
but the novelty soon wears thin,
181
00:21:21,600 --> 00:21:24,720
especially when everyone else
is having all the fun.
182
00:21:32,320 --> 00:21:34,560
The baby-sitter decides
to join the game...
183
00:21:36,400 --> 00:21:39,840
..while the baby
clings on for dear life.
184
00:21:58,040 --> 00:22:01,280
But some challenges test
the baby's grip to the limit.
185
00:22:03,080 --> 00:22:06,640
An almost sheer drop of 20 metres.
186
00:22:09,240 --> 00:22:12,920
The babysitter
is oblivious to the danger.
187
00:22:21,440 --> 00:22:23,920
For the baby, a final indignity.
188
00:22:23,920 --> 00:22:26,000
SQUEALING
189
00:22:28,320 --> 00:22:31,440
Time for the mother
to reclaim her infant.
190
00:22:33,240 --> 00:22:36,280
The babysitter wants a break, too.
191
00:22:36,280 --> 00:22:40,840
There are plenty more volunteers,
but for both baby and mother,
192
00:22:40,840 --> 00:22:42,640
enough is enough.
193
00:22:50,720 --> 00:22:52,440
It seems traumatic,
194
00:22:52,440 --> 00:22:55,400
but this is how teenagers
learn the parenting skills
195
00:22:55,400 --> 00:22:56,800
they'll need in the future.
196
00:23:00,680 --> 00:23:03,200
There's no shortage of love here,
197
00:23:03,200 --> 00:23:06,240
even if, at times, it's tough love.
198
00:23:17,400 --> 00:23:19,560
The prairies of North America,
199
00:23:19,560 --> 00:23:22,960
home to an animal
with a surprisingly-loving nature.
200
00:23:29,680 --> 00:23:33,160
This inquisitive soul
is the prairie dog.
201
00:23:35,440 --> 00:23:37,080
He has a new neighbour.
202
00:23:38,040 --> 00:23:39,200
Spy prairie dog.
203
00:23:45,040 --> 00:23:47,680
CHIRPING
204
00:23:47,680 --> 00:23:50,640
Everyone's curious
to see the new arrival.
205
00:24:02,240 --> 00:24:06,360
They live in towns,
made up of around 20 family groups.
206
00:24:07,960 --> 00:24:11,720
In these wide open spaces,
everyone relies on each other
207
00:24:11,720 --> 00:24:13,400
to watch for danger.
208
00:24:16,240 --> 00:24:19,040
So, to strengthen
their family connections,
209
00:24:19,040 --> 00:24:21,920
they have an endearing way
to express their affection.
210
00:24:23,160 --> 00:24:24,520
Kissing.
211
00:24:25,560 --> 00:24:27,000
Like a human kiss,
212
00:24:27,000 --> 00:24:31,120
it's thought to encourage the bond
of love and release oxytocin -
213
00:24:31,120 --> 00:24:33,640
a pleasure hormone
that floods the brain.
214
00:24:40,760 --> 00:24:44,400
It also helps
identify family members
215
00:24:44,400 --> 00:24:46,680
and strangers from out of town.
216
00:24:49,200 --> 00:24:52,560
But when a rival male
blatantly steals a kiss,
217
00:24:52,560 --> 00:24:54,920
it doesn't go down well
with the head of the family.
218
00:25:09,280 --> 00:25:13,160
The cheating female
wisely hides, as fur flies.
219
00:25:44,200 --> 00:25:45,720
Love rival gone,
220
00:25:45,720 --> 00:25:47,680
the prairie dogs regroup,
221
00:25:47,680 --> 00:25:51,760
with an enthusiastic display
called a jump-yip.
222
00:25:51,760 --> 00:25:55,560
The jump-yip shows the colony
is alert and on guard.
223
00:25:55,560 --> 00:25:58,600
It also reinforces its unity,
224
00:25:58,600 --> 00:26:02,160
ensuring everyone
is on the same wavelength.
225
00:26:03,360 --> 00:26:05,680
Even spy prairie dog gives it a go.
226
00:26:05,680 --> 00:26:07,760
CHIRPING
227
00:26:44,320 --> 00:26:46,040
CHIRPING
228
00:26:48,880 --> 00:26:51,200
BELLOWING
229
00:26:51,200 --> 00:26:53,600
Back on the African savanna,
230
00:26:53,600 --> 00:26:56,600
the new-born elephant
is on the move
231
00:26:56,600 --> 00:26:59,480
and he now needs the protection
of his family more than ever.
232
00:27:04,760 --> 00:27:06,920
The spy creatures are on duty, too.
233
00:27:21,000 --> 00:27:25,200
As they travel, the mother uses
her tail to make sure her baby
234
00:27:25,200 --> 00:27:27,320
is always in touching distance...
235
00:27:29,040 --> 00:27:32,960
..for danger can come from
the most unexpected places.
236
00:27:32,960 --> 00:27:35,720
And wild dogs can be a threat,
237
00:27:35,720 --> 00:27:38,720
especially when they have
their own pups to protect.
238
00:27:41,640 --> 00:27:46,000
For now, they are blissfully unaware
that the elephants are close.
239
00:27:46,000 --> 00:27:47,960
The pups are constantly playing,
240
00:27:47,960 --> 00:27:52,440
building the social skills they need
to be fully part of the pack.
241
00:27:53,520 --> 00:27:55,560
ELEPHANT BELLOWING
242
00:27:55,560 --> 00:27:57,440
But the elephants
are getting closer.
243
00:27:57,440 --> 00:28:00,320
They could easily destroy
the den and crush the pups.
244
00:28:01,320 --> 00:28:04,520
The dogs advance,
to meet the threat.
245
00:28:27,280 --> 00:28:30,080
Wild dogs are effective killers,
246
00:28:30,080 --> 00:28:32,120
able to take down
a new-born elephant.
247
00:28:33,240 --> 00:28:38,080
But their only concern now
is the safety of their own young.
248
00:28:38,080 --> 00:28:40,720
Stragglers are rounded up.
249
00:28:42,640 --> 00:28:45,760
The elephants are equally concerned
for their own baby.
250
00:28:47,880 --> 00:28:50,880
They shepherd him
behind a protective wall of legs.
251
00:28:52,840 --> 00:28:57,200
The dogs create their own barrier
between the elephants and the den.
252
00:28:58,320 --> 00:28:59,400
It's a showdown.
253
00:29:02,880 --> 00:29:04,480
The matriarch leads the charge.
254
00:29:04,480 --> 00:29:05,800
BELLOWING
255
00:29:12,160 --> 00:29:14,960
She's the most experienced
member of the family.
256
00:29:27,560 --> 00:29:29,640
As the conflict escalates,
257
00:29:29,640 --> 00:29:32,720
the elephants put on
a united show of strength...
258
00:29:34,640 --> 00:29:37,680
..with the baby hidden behind
a moving barrier of legs.
259
00:29:52,640 --> 00:29:56,720
Eventually, the two sides
accept an uneasy truce.
260
00:29:59,120 --> 00:30:02,920
Both loyal and loving families
know there's too much to lose
261
00:30:02,920 --> 00:30:04,720
from further confrontation.
262
00:30:09,880 --> 00:30:12,880
With spy tortoise
now fully accepted by the herd...
263
00:30:14,960 --> 00:30:17,480
..the elephants bring him
along for the ride.
264
00:30:25,240 --> 00:30:26,720
Albeit, a brief one.
265
00:30:34,520 --> 00:30:37,760
The affection that binds
families together may be strong,
266
00:30:37,760 --> 00:30:42,320
but the bond between courting
couples is in different realm.
267
00:30:43,600 --> 00:30:46,840
In southern Kenya,
love is blossoming.
268
00:30:49,040 --> 00:30:50,920
This male red-billed hornbill
269
00:30:50,920 --> 00:30:54,440
has found the perfect spot
to bring up a family.
270
00:30:56,120 --> 00:30:58,960
His mate is never far away.
271
00:31:02,280 --> 00:31:04,160
He performs a little dance,
272
00:31:04,160 --> 00:31:06,360
to entice her to take a closer look.
273
00:31:15,800 --> 00:31:19,120
She shows her approval
by starting to spruce the place up.
274
00:31:24,880 --> 00:31:28,920
They now face a challenge that will
test their commitment to the limit.
275
00:31:32,600 --> 00:31:34,360
They set to work, gathering mud -
276
00:31:34,360 --> 00:31:36,040
a central element to their plan.
277
00:31:51,200 --> 00:31:54,080
Their aim is
to make the entrance smaller.
278
00:31:58,920 --> 00:32:02,040
They also add
poisonous millipedes to the mix,
279
00:32:02,040 --> 00:32:06,800
creating an insect repellent that
keeps nest-raiding pests at bay.
280
00:32:15,120 --> 00:32:18,760
The hole is shrinking fast,
so before it gets too small,
281
00:32:18,760 --> 00:32:20,960
the female must move in.
282
00:32:20,960 --> 00:32:25,520
This tiny chamber will become
her home for the next 12 weeks.
283
00:32:27,200 --> 00:32:28,760
She's a willing captive,
284
00:32:28,760 --> 00:32:32,280
even using her own droppings
to help narrow the hole.
285
00:32:33,680 --> 00:32:37,800
She now relies on her mate
to deliver more building materials.
286
00:32:39,760 --> 00:32:43,640
Working as a team, the female
narrows the entrance from within.
287
00:32:43,640 --> 00:32:47,240
Their plan is to make a prison cell,
288
00:32:47,240 --> 00:32:51,440
but one purely for her protection,
as it keeps predators, like snakes,
289
00:32:51,440 --> 00:32:52,680
from entering.
290
00:32:56,280 --> 00:32:59,760
Soon, the hole
is reduced to a mere slit,
291
00:32:59,760 --> 00:33:02,720
just big enough
to squeeze in supplies.
292
00:33:08,080 --> 00:33:10,120
Eventually, the eggs are laid.
293
00:33:11,960 --> 00:33:14,920
Among her clutch
is a special spy egg,
294
00:33:14,920 --> 00:33:19,480
one that will record the next
stage in this incredible story.
295
00:33:21,920 --> 00:33:23,640
As the weeks go by,
296
00:33:23,640 --> 00:33:27,440
her mate's only concern
is to keep his partner well fed.
297
00:33:27,440 --> 00:33:30,880
She is completely dependent on him.
298
00:33:32,200 --> 00:33:37,880
He brings her up to 20 large insects
each day, while she incubates.
299
00:33:40,120 --> 00:33:42,800
But what goes in, must come out.
300
00:33:44,640 --> 00:33:46,560
Nest hygiene is essential.
301
00:33:55,520 --> 00:33:59,520
25 days after laying,
the moment has arrived.
302
00:33:59,520 --> 00:34:01,880
CHIRPING
303
00:34:01,880 --> 00:34:03,280
She has a brood of three,
304
00:34:03,280 --> 00:34:05,600
plus one adopted chick(!)
305
00:34:05,600 --> 00:34:09,200
Spy egg has become spy hatchling.
306
00:34:10,280 --> 00:34:13,440
One chick takes him under her wing.
307
00:34:15,440 --> 00:34:18,560
With more mouths to feed,
the male is in overdrive,
308
00:34:18,560 --> 00:34:22,000
finding at least
70 insects each day.
309
00:34:27,640 --> 00:34:29,640
They have voracious appetites...
310
00:34:30,640 --> 00:34:34,000
..but at least
one beak doesn't need feeding.
311
00:34:36,320 --> 00:34:39,440
The mother divvies up the food
between her growing brood
312
00:34:39,440 --> 00:34:40,640
as best she can.
313
00:34:45,560 --> 00:34:48,360
But after being cooped up
for over two months,
314
00:34:48,360 --> 00:34:52,280
the lack of space
and constant quarrelling
315
00:34:52,280 --> 00:34:54,640
is getting too much for her.
316
00:34:54,640 --> 00:34:57,320
She starts to chisel her way out...
317
00:34:59,480 --> 00:35:01,800
..testing the hole for size.
318
00:35:05,360 --> 00:35:08,600
To keep her babies safe,
it must stay predator-proof.
319
00:35:11,680 --> 00:35:15,880
It seems an impossible squeeze,
so easy to get stuck.
320
00:35:30,680 --> 00:35:31,720
Freedom.
321
00:35:36,120 --> 00:35:38,800
The chicks instinctively
use spittle and droppings
322
00:35:38,800 --> 00:35:40,720
to close up the entrance again.
323
00:35:44,640 --> 00:35:47,560
Now, the hard work can be shared.
324
00:35:47,560 --> 00:35:51,040
Each chick needs
one insect every ten minutes.
325
00:35:51,040 --> 00:35:53,600
One bird alone
couldn't keep up with demand.
326
00:35:53,600 --> 00:35:56,560
Spy chick even gets a mouthful.
327
00:35:58,600 --> 00:36:00,920
But, of course, he shares it around.
328
00:36:03,720 --> 00:36:07,680
The parents will feed their
chicks for another three weeks,
329
00:36:07,680 --> 00:36:09,760
until they are ready to fledge.
330
00:36:11,560 --> 00:36:17,160
Few birds show such dedication. It's
the ultimate expression of trust.
331
00:36:20,840 --> 00:36:24,600
They'll remain faithful
for their entire lives.
332
00:36:26,520 --> 00:36:29,880
Not all partners
show the same devotion.
333
00:36:37,520 --> 00:36:39,880
The cold wastes of Antarctica.
334
00:36:49,080 --> 00:36:51,160
For Adelie penguins,
335
00:36:51,160 --> 00:36:54,720
the challenges start the moment they
arrive from the ocean, to breed.
336
00:36:56,400 --> 00:36:58,640
The males race
to their nesting grounds,
337
00:36:58,640 --> 00:37:01,240
desperate for a head start
on their rivals.
338
00:37:04,040 --> 00:37:05,320
As soon as they arrive,
339
00:37:05,320 --> 00:37:09,720
the quarrels begin
over who gets the best nest sites.
340
00:37:19,240 --> 00:37:21,760
Spy Adelie enters the fray.
341
00:37:25,280 --> 00:37:27,880
But to film
their complicated love life,
342
00:37:27,880 --> 00:37:29,680
it's vital he fits in.
343
00:37:31,040 --> 00:37:34,400
His courtship display
makes him one of the gang,
344
00:37:34,400 --> 00:37:36,360
as they wait
for their mates to arrive.
345
00:37:39,880 --> 00:37:43,840
The females are fussy partners
and the males fight over pebbles,
346
00:37:43,840 --> 00:37:47,760
to make sure they build them
the biggest and finest nests.
347
00:37:52,200 --> 00:37:54,080
And they don't mind
who gets in their way.
348
00:38:07,960 --> 00:38:10,000
A late arrival
hurries into the colony.
349
00:38:18,320 --> 00:38:22,080
With the best nest sites taken,
he is forced to the outskirts,
350
00:38:22,080 --> 00:38:24,400
where no-one wants to be.
351
00:38:25,440 --> 00:38:28,680
It's a cold and soggy place
to build a love nest,
352
00:38:28,680 --> 00:38:32,480
especially when the point
of the pebbles is to keep their eggs
353
00:38:32,480 --> 00:38:34,360
raised and dry.
354
00:38:37,080 --> 00:38:39,640
Spy Adelie helps as best he can...
355
00:38:41,360 --> 00:38:42,880
..with a well-placed pebble cam.
356
00:38:51,600 --> 00:38:53,760
But the latecomer isn't discouraged
357
00:38:53,760 --> 00:38:56,600
and gathers more pebbles,
as fast as he can.
358
00:39:01,360 --> 00:39:04,680
But round here, you can't
turn your back for a second.
359
00:39:04,680 --> 00:39:08,360
As soon as he puts it down,
his pebble is stolen.
360
00:39:10,440 --> 00:39:13,360
The thief embellishes
his impressive nest.
361
00:39:14,760 --> 00:39:17,800
Oblivious, the latecomer
is travelling ever further
362
00:39:17,800 --> 00:39:19,240
to find stones...
363
00:39:22,600 --> 00:39:25,400
..while the crook
takes advantage of the moment.
364
00:39:29,200 --> 00:39:33,400
He may have no moral code, but he
certainly has a magnificent nest.
365
00:39:35,720 --> 00:39:40,200
In contrast, the latecomer's
nest remains in a sorry state
366
00:39:40,200 --> 00:39:43,720
and the criminal penguin is getting
ever more brazen...
367
00:39:43,720 --> 00:39:44,760
SQUAWKING
368
00:39:46,600 --> 00:39:50,160
..taking another trophy back
to his ever-growing pile,
369
00:39:51,240 --> 00:39:54,680
..while the latecomer
is becoming despondent.
370
00:39:57,760 --> 00:39:59,320
To make matters worse,
371
00:39:59,320 --> 00:40:02,280
the females have started to arrive.
372
00:40:08,000 --> 00:40:10,880
Females often remain
faithful to their partners,
373
00:40:10,880 --> 00:40:13,680
but only if the nests
meet their high expectations.
374
00:40:18,080 --> 00:40:21,200
So, for the latecomer,
the pressure is on.
375
00:40:25,440 --> 00:40:27,560
She makes a considered inspection.
376
00:40:29,960 --> 00:40:32,760
Perhaps one last stone
will swing it?
377
00:40:41,400 --> 00:40:43,200
He awaits her verdict.
378
00:40:50,320 --> 00:40:53,200
Her reaction
is somewhat disappointing.
379
00:40:55,280 --> 00:41:00,560
Nearby, the bachelor thief proudly
shows off his ill-gotten gains.
380
00:41:02,520 --> 00:41:05,320
There is only so much
a female penguin can resist.
381
00:41:10,480 --> 00:41:13,640
She wants a male
with a dry, raised nest,
382
00:41:13,640 --> 00:41:15,720
where her eggs will survive.
383
00:41:15,720 --> 00:41:17,600
And she's found one.
384
00:41:22,480 --> 00:41:26,000
But her jilted partner
won't give up without a fight.
385
00:41:55,280 --> 00:41:57,440
It was a brave effort,
386
00:41:57,440 --> 00:41:59,240
but it wasn't enough.
387
00:42:01,040 --> 00:42:04,040
She chooses the thieving male
with the finest nest.
388
00:42:05,400 --> 00:42:07,600
Her mate makes one last plea...
389
00:42:09,280 --> 00:42:11,240
..but it's all in vain...
390
00:42:14,120 --> 00:42:17,800
..and he's subjected
to the final indignity.
391
00:42:32,760 --> 00:42:37,520
But Adelies are plucky
and irrepressible birds
392
00:42:37,520 --> 00:42:41,520
and, if you
can't beat them, join them.
393
00:42:43,280 --> 00:42:46,320
You can always build another nest,
394
00:42:46,320 --> 00:42:49,200
especially with
a little help from a friend.
395
00:42:53,880 --> 00:42:55,880
Back in the warmth of Africa,
396
00:42:55,880 --> 00:43:00,360
spy tortoise is going undercover
in more familiar territory.
397
00:43:02,440 --> 00:43:04,840
He's spending time
with real tortoises,
398
00:43:04,840 --> 00:43:08,720
to record what insights
into love they might offer.
399
00:43:10,000 --> 00:43:14,000
This leopard tortoise is desperately
seeking a romantic liaison.
400
00:43:16,600 --> 00:43:19,640
As he sets off
on this amorous quest,
401
00:43:19,640 --> 00:43:22,120
spy tortoise plays gooseberry.
402
00:43:30,960 --> 00:43:34,400
The hopeful suitor's technique
lacks a certain subtlety.
403
00:43:40,680 --> 00:43:42,520
First, he gives chase.
404
00:43:53,400 --> 00:43:56,080
And then, a bit of a barge.
405
00:43:56,080 --> 00:43:57,560
CLUNKING
406
00:43:57,560 --> 00:44:02,000
If you're covered by a hard shell,
it's difficult to be sensitive.
407
00:44:04,000 --> 00:44:07,240
And there's nothing subtle
about what happens next.
408
00:44:26,080 --> 00:44:28,920
GASPING
409
00:44:35,240 --> 00:44:38,240
Spy tortoise is here to observe,
410
00:44:38,240 --> 00:44:41,760
but things don't always go to plan.
411
00:45:06,960 --> 00:45:09,600
Probably best
to forget that ever happened.
412
00:45:13,680 --> 00:45:15,000
For our spy creatures,
413
00:45:15,000 --> 00:45:18,880
being immersed in the world of
animals is not without its hazards.
414
00:45:24,760 --> 00:45:26,480
In Rajasthan,
415
00:45:26,480 --> 00:45:30,800
the temple languors have taken spy
monkey into the heart of the family.
416
00:45:32,280 --> 00:45:34,680
But some are keen to take
the budding relationship
417
00:45:34,680 --> 00:45:35,720
to the next level
418
00:45:35,720 --> 00:45:38,320
and are getting
a little too familiar.
419
00:45:42,160 --> 00:45:44,480
One seems to want to babysit her.
420
00:45:49,400 --> 00:45:51,080
But disaster strikes.
421
00:45:53,120 --> 00:45:55,880
An injured baby
is a cause for concern.
422
00:46:04,920 --> 00:46:07,800
And this languor
seems to believe she's died.
423
00:46:10,720 --> 00:46:14,360
Then,
something extraordinary happens.
424
00:46:21,400 --> 00:46:25,240
The monkeys gather round
the motionless spy creature,
425
00:46:25,240 --> 00:46:27,160
as if it is a real baby.
426
00:46:50,080 --> 00:46:54,120
They react just as they do
when their own babies die.
427
00:47:02,760 --> 00:47:06,240
A calm and contemplative mood
descends on the colony.
428
00:47:08,880 --> 00:47:12,960
There's a sense of grief,
as well as empathy for one another.
429
00:47:17,080 --> 00:47:20,240
Quite accidentally, our spy creature
430
00:47:20,240 --> 00:47:24,600
is at the centre of something
extraordinary, capturing emotions
431
00:47:24,600 --> 00:47:26,440
that have rarely been observed.
432
00:47:37,000 --> 00:47:41,440
Such apparent expressions of grief
may not be unique to primates.
433
00:47:51,160 --> 00:47:53,040
On the African savanna,
434
00:47:53,040 --> 00:47:56,640
spy tortoise is party
to another unique event.
435
00:48:02,040 --> 00:48:05,320
Giraffes are appearing
from every direction.
436
00:48:10,040 --> 00:48:12,560
This is what they've come to see.
437
00:48:17,840 --> 00:48:19,840
An old giraffe has passed away
438
00:48:19,840 --> 00:48:23,240
and it seems
to have profoundly affected those
439
00:48:23,240 --> 00:48:25,520
who share these vast grasslands.
440
00:48:33,280 --> 00:48:34,600
And more keep arriving,
441
00:48:34,600 --> 00:48:38,680
creating an unprecedented assembly,
never witnessed before.
442
00:49:09,080 --> 00:49:12,280
The giraffes kept arriving
throughout the day,
443
00:49:12,280 --> 00:49:15,680
seemingly paying respects
to the old male.
444
00:49:19,440 --> 00:49:21,560
An awareness of death
445
00:49:21,560 --> 00:49:24,000
was previously believed
to have involved just a few
446
00:49:24,000 --> 00:49:28,560
highly intelligent species,
but this seems to suggest otherwise.
447
00:49:46,840 --> 00:49:52,040
Such deep feelings are to be
more expected among chimpanzees,
448
00:49:52,040 --> 00:49:56,880
but these intelligent animals
still have the capacity to surprise.
449
00:49:59,120 --> 00:50:00,760
In the forests of Senegal,
450
00:50:00,760 --> 00:50:03,960
spy bushbaby is part
of a team of spy cameras
451
00:50:03,960 --> 00:50:08,080
capturing intimate views
of our closest living relatives.
452
00:50:20,480 --> 00:50:23,560
Here, the family lives
a charmed existence.
453
00:50:30,960 --> 00:50:35,520
Parental love and friendships form
the foundation of their society.
454
00:50:39,240 --> 00:50:42,320
Spy tortoise is also being deployed.
455
00:50:49,520 --> 00:50:52,320
But these are
highly-perceptive animals...
456
00:51:05,600 --> 00:51:08,600
..and something's not quite right.
457
00:51:16,840 --> 00:51:19,800
This five-year-old checks
what the others are thinking.
458
00:51:23,680 --> 00:51:25,640
They seem equally baffled.
459
00:51:33,520 --> 00:51:37,920
But with his curiosity piqued,
he simply can't stay away.
460
00:51:53,320 --> 00:51:57,920
As his interest grows, so does
the strength of his feelings.
461
00:51:57,920 --> 00:52:00,200
SCREECHING
462
00:52:03,080 --> 00:52:07,440
He just has to have
spy tortoise all to himself.
463
00:52:25,320 --> 00:52:28,560
He hides with it
in his leafy daybed,
464
00:52:28,560 --> 00:52:30,400
where he'd normally take a nap.
465
00:52:36,200 --> 00:52:38,680
But he's too excited to sleep.
466
00:52:45,400 --> 00:52:50,240
He's torn between using it
as a pillow and giving it cuddle.
467
00:52:50,240 --> 00:52:53,560
It's somewhere between
a toy and a pet.
468
00:53:02,520 --> 00:53:07,280
SCREECHING
469
00:53:17,040 --> 00:53:19,240
It's definitely not for sharing.
470
00:53:56,880 --> 00:53:59,560
Chimps don't normally
have possessions,
471
00:53:59,560 --> 00:54:02,760
but spy tortoise
has stirred new emotions.
472
00:54:09,320 --> 00:54:10,760
Elsewhere in the forest,
473
00:54:10,760 --> 00:54:15,240
spy bushbaby is helping document
an equally-unique event.
474
00:54:24,160 --> 00:54:28,080
One of the older chimps
is playing with a tiny kitten.
475
00:54:32,080 --> 00:54:35,680
It's the offspring of a genet cat
found abandoned in the forest.
476
00:54:43,960 --> 00:54:47,640
He treats it with kid gloves,
mindful not to hurt it.
477
00:54:52,880 --> 00:54:55,120
Even a nip is tolerated.
478
00:54:58,200 --> 00:55:00,120
The way he responds to the genet
479
00:55:00,120 --> 00:55:03,920
shows a very rare emotion
in animals - empathy.
480
00:55:07,680 --> 00:55:09,120
Other chimps are intrigued.
481
00:55:23,360 --> 00:55:25,760
And one shows an unwelcome interest.
482
00:55:29,800 --> 00:55:32,960
This older chimp
is used to having his own way,
483
00:55:32,960 --> 00:55:36,680
but without any feelings for
the kitten, he's a bit too rough.
484
00:55:36,680 --> 00:55:39,840
The owner shows
real concern and intervenes,
485
00:55:39,840 --> 00:55:42,320
to protect his vulnerable pet.
486
00:55:44,720 --> 00:55:46,400
And takes it from harm's way.
487
00:55:57,440 --> 00:55:59,840
They hide behind a termite mound.
488
00:56:00,840 --> 00:56:05,640
It's not just a private spot,
it's also a chance for a snack.
489
00:56:11,000 --> 00:56:14,240
By using a stick,
he can fish for termites.
490
00:56:19,400 --> 00:56:22,360
It's an intimate moment
enjoyed with a special companion.
491
00:56:27,400 --> 00:56:30,840
Perhaps this is how
human pet-keeping began.
492
00:56:35,680 --> 00:56:39,160
This is a glimpse
of something quite remarkable -
493
00:56:39,160 --> 00:56:42,480
the first stirrings
of empathy for another species.
494
00:56:48,560 --> 00:56:50,840
In the animal world,
495
00:56:50,840 --> 00:56:53,320
there are more ways
of showing love and affection
496
00:56:53,320 --> 00:56:55,520
than we ever thought possible.
497
00:56:57,200 --> 00:56:59,280
From maternal devotion,
498
00:56:59,280 --> 00:57:01,680
to family affection.
499
00:57:01,680 --> 00:57:02,760
Through jealousy...
500
00:57:05,080 --> 00:57:06,640
..grief...
501
00:57:07,680 --> 00:57:09,240
..and romantic liaisons.
502
00:57:10,360 --> 00:57:14,080
These many incarnations of love
in the animal world may offer
503
00:57:14,080 --> 00:57:16,680
a mirror
to our own complex feelings.
504
00:57:18,080 --> 00:57:20,680
Next time,
a team of new spy creatures
505
00:57:20,680 --> 00:57:24,000
film how intelligent
animals really are,
506
00:57:24,000 --> 00:57:27,040
with some
extraordinary revelations.
