S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
In this area of northern Kenya,
0:02
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
almost one in five herds are orphan herds.
0:05
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
This one is led by
0:09
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
a young 13 -year -old female called Habiba.
0:12
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
So young,
0:14
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
she lacks the knowledge and experience needed to keep them safe.
0:18
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
The life of this young herd hangs constantly
0:22
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
in the balance.
0:23
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
Just one wrong decision can be fatal,
0:27
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
as another orphan group discovered a few years ago.
0:39
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
Their inexperienced leader decided to cross a river when it was in full
0:43
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
flood.
0:44
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
A huge error in judgment that put the lives
0:48
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
of the young calves in danger.
0:50
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
This
1:26
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
family was lucky.
1:27
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
The calves were washed ashore.
1:29
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
But it's a reminder of how important an older,
1:33
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
knowledgeable leader is.
1:34
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
Habiba
1:40
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
has a lot on her plate.
1:42
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
Not only does she have the huge responsibility of keeping her herd
1:46
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
safe,
1:48
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
She's also a first -time mother,
1:50
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
Tuzawadi,
1:51
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
who's already proving quite a handful.
1:54
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
Only
2:01
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
a year old,
2:02
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
he's a plucky little character,
2:03
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
always wandering off on his own.
2:07
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
Keeping
2:30
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
him safe is a full -time job in itself.
2:33
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
In such
2:37
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
difficult terrain,
2:38
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
good tracking skills are essential to work out where Matt has moved to
2:42
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
since his last known position.
2:43
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
A
2:50
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
fresh footprint is just the sign the team need.
2:55
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
The position of the front toe shows that Matt is heading south.
2:59
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
But it's too risky to track
3:03
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
a seven -tonne must elephant on foot in thick brush.
3:06
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
So the team must navigate their way in by jeep.
3:10
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
Soon,
3:20
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
Matt is in sight.
3:21
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
And he's not alone.
3:23
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
He's
3:28
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
in hot pursuit of a female.
3:30
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
And the fact that he's guarding her suggests she's
3:34
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
an oestrus and ready to mate.
3:39
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
But there are plenty of younger bulls here,
3:41
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
and they're all interested in her too.
3:43
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
For
3:49
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
the next few days,
3:50
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
until the female is no longer receptive,
3:52
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
Matt must guard her 24 -7.
3:55
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
He
4:00
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
also needs to show the young bulls who's boss.
4:03
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
As
4:20
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
he sees off the competition,
4:21
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
the crew get caught in the action.
4:23
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
But
4:30
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
as they move out of the way,
4:31
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
they run into more trouble.
4:33
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
It's
4:46
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
not a good time to get stuck on a log.
5:18
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
Luckily, Matt is busy with the younger males.
5:20
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
Having
5:33
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
finally found a receptive female,
5:35
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
Matt won't have a chance to mate unless he can get her away from
5:39
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
the other males.
5:40
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
And that's no mean feat.
5:42
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
The
5:48
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
latest tracking data shows that this year's gathering will soon be coming to
5:52
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
an end.
5:53
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
As the vegetation in
5:57
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
the reserve starts to dry up,
5:59
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
the elephants will take their cue and begin their journey home.
6:02
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
Bulls
6:07
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
will be dropping out of must and moving on.
6:13
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
and families will begin to disperse,
6:15
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
heading back to their home ranges across northern
6:19
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
Kenya.
6:20
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
It's
6:24
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
a bittersweet time for the scientists,
6:25
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
as the constant threat of poaching means there's no certainty of
6:30
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
seeing elephants like Matt again.
6:31
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
With
6:38
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
the herd soon disappearing,
6:39
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
time is running out for Habiba and her family to find help.
6:44
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
But
6:49
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
her caller tells us she's heading in the direction of a well -established herd.
7:01
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
Its leader is an experienced 50 -year -old tuskless matriarch,
7:05
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
the ideal kind of female for Habiba to learn
7:09
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
from. Little
7:14
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
Zawadi makes the first move and approaches a calf in the group.
7:18
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
He's
7:26
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
put in his place with a gentle nudge,
7:28
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
but he doesn't retreat far.
7:31
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
At
7:35
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
last, they seem to have found a herd that will tolerate them.
7:47
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
Desperate for a playmate,
7:49
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
it's not long before Zawadi finds a slightly older calf willing
7:53
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
to be his sparring partner.
7:54
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
This
7:59
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
is just the kind of interaction he needs.
8:02
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
To grow into a majestic
8:06
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
bull like Matt,
8:07
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
capable of fighting off rival males,
8:09
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
it's vital that he gets to play fight first within a family group like
8:13
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
this one.
8:14
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
After
8:20
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
the two herds have been mingling for a while,
8:22
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
something remarkable happens.
8:26
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
As the tuskless matriarch leads her group away,
8:29
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
the orphan herd leaves with them.
8:31
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
Both
8:35
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
families are now moving as one.
8:38
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
Against
8:43
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
all odds,
8:43
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
the orphans have finally found a family willing
8:48
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
to help them.
8:48
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
At last,
8:52
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
little Zawadi,
8:53
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
Habiba and the others have older elephants to learn from.
8:57
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
Elephants who will hopefully give them the support they so desperately
9:01
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
need.
9:11
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
As the number of orphan herds increases,
9:13
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
scientists are discovering that elephants are finding new ways
9:17
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
to adapt.
9:18
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
An intelligent,
9:20
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
hyper -social species is learning to respond to
9:24
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
the new challenges it faces.
9:26
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
Over
9:35
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
the past month,
9:36
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
Samburu National Reserve has been the setting for a remarkable
9:40
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
gathering.
9:43
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
Using data from satellite collars,
9:45
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
this has been a unique opportunity to see how young orphan
9:49
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
herds are coping with the loss of their matriarchs.
9:52
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
How bull elephants
9:57
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
select females to pass on their legacy.
10:02
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
and to witness incredible new elephant behavior.
10:06
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
It's a lone wolf.
10:07
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
Now
10:12
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
that it's broken cover,
10:13
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
the wolf is easy for the caribou to spot.
10:16
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
It's
10:20
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
taking a chance.
10:21
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
A fully grown caribou weighs twice as much as the wolf does
10:26
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
and has a powerful kick.
10:28
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
But the opportunity of a prize kill is
10:33
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
worth the risk.
10:33
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
Having
11:34
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
panicked the herd,
11:35
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
the wolf looks for a weaker or slower individual.
11:48
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
As the herd splinters and reforms,
11:51
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
some of the caribou lose sight of their attacker,
11:54
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
giving the wolf its opportunity.
11:56
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
The
12:07
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
wolf must grab the caribou by the throat.
12:10
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
But one well -aimed hoof could end this battle
12:14
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
in the caribou's favour.
12:15
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
Survival
13:10
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
is finely balanced up here.
13:12
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
This
13:17
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
time, the wolf has won.
13:19
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
With just ten days left to calving,
13:23
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
time is against them.
13:27
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
Taking the mountain route will add miles to the journey,
13:30
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
causing a potentially disastrous delay.
13:32
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
It would also bring them into contact
13:37
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
with more predators.
13:38
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
Just ahead,
13:39
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
a bear is on the prowl.
13:41
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
Despite
13:50
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
the strong currents,
13:51
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
the herd is forced to cross the river.
13:54
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
The
14:05
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
lead female enters the water and the others follow.
14:09
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
This could be a catastrophic mistake.
14:18
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
The force of the meltwater has created a powerful set of rapids.
14:22
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
But
14:27
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
the caribou forge ahead regardless.
14:29
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
The
14:34
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
lead animals are struggling to make progress and are
14:39
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
regularly sucked under by the powerful eddies.
14:41
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
The
14:47
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
rapids are overwhelming.
15:19
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
Before long,
15:20
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
the rest of the caribou have beaten a retreat.
15:23
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
With nowhere left to turn,
15:26
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
they opt for the mountain route.
15:28
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
But that means heading
15:32
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
directly towards a bear.
15:33
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
And he isn't alone.
15:37
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
A
15:47
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
wolf slips through the trees below the caribou.
15:49
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
Perhaps
16:02
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
sensing the danger,
16:03
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
they change course again,
16:05
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
returning to the river further upstream.
16:08
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
And from here,
16:10
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
there's only one option.
16:16
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
At this point,
16:16
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
the river is slightly shallower than the first spot they tried,
16:20
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
but the current is still strong.
16:22
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
The
16:27
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
older females in the group lead the way again.
16:29
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
Suddenly,
16:33
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
a yearling drifts away from its mother.
16:36
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
Even
16:57
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
some of the adults are struggling.
16:58
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
The
17:08
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
yearling is out of its depth,
17:09
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
on its own and heading towards the rapids.
17:16
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
But she has one thing on her side.
17:18
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
Caribou fur is hollow to help insulate against the cold,
17:22
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
which means
17:27
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
she can float.
17:28
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
It's
17:40
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
been a close call,
17:42
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
but the break -off group have successfully rejoined the herd.
17:45
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
With their goal so close,
17:47
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
the pregnant caribou are even prepared to leave behind their yearlings
17:51
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
to get there on time.
17:53
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
Like
18:00
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
their mothers, the yearlings are close to collapse.
18:06
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
If this one can't find the energy to keep going,
18:09
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
its chances are poor.
18:11
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
On
18:17
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
its own, it will quickly be taken by predators.
18:20
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
Well
18:28
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
over 5 ,000 caribou die during each spring migration,
18:31
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
either from sheer exhaustion or predation.
18:36
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
The only way to
18:40
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
avoid that fate is to get up and move on.
18:44
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
The
19:14
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
lead caribou finally head out of the mountains and onto the
19:18
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
coastal plains.
19:44
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
After over 300 miles and barely any food,
19:48
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
they've timed this migration to perfection.
19:51
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
The cotton grass sprouts and flowers in the two
19:55
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
weeks after the snow has melted.
19:57
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
It's now at its most nutritious.
20:05
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
The thousands of caribou now moving onto the plains are replenishing
20:09
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
their reserves.
20:10
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
And it's not just a case of simple refueling.
20:14
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
Scientists have shown that eating the grass at this
20:18
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
specific time helps the mothers to produce a richer milk for
20:22
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
their newborn calves,
20:23
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
greatly improving their chances of survival.
20:26
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
This year's decision to remain
20:30
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
on the plains for longer than usual may have something to do with the fact that
20:34
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
this is an El Nino year.
20:39
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
An oceanic event linked to the Pacific thousands of miles away,
20:44
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
El Niño has wide -ranging atmospheric effects,
20:47
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
and this includes delaying the rains in Africa.
20:50
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
Perhaps the majority of zebra have responded
20:54
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
to the lack of heavy rains by playing it safe in Chobe.
20:58
S… Speaker 3 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
But
21:10
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
if the zebra want to give their foals the best possible start in life,
21:14
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
they'll have to set off for Naipan soon.
21:21
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
Of all the collared zebra,
21:23
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
only Sox and her family are still moving south.
21:26
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
So who's made the right decision?
21:29
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
Sox is now 100 kilometers ahead of the
21:33
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
others. She's picked up her pace to 8 kilometers per hour and is traveling
21:37
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
in a straight line to Naipan.
21:39
S… Speaker 3 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
How
21:46
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
does she know where to go?
21:47
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
Incredibly,
21:50
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
in the flat,
21:51
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
featureless wilderness of Botswana,
21:53
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
zebra navigate perfectly with no hills or landmarks for reference.
22:01
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
Scientists still don't understand exactly how they do this.
22:05
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
Until very recently,
22:08
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
it was assumed these roots were learned and then passed down generation
22:13
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
to generation.
22:14
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
But something happened in northern Botswana that turned this theory
22:18
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
on its head.
22:19
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
In the 1950s and 60s,
22:23
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
extensive livestock fences were erected across the landscape
22:27
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
in an attempt to stop diseases being transmitted from wildlife to
22:31
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
domestic cattle.
22:32
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
But the fences also prevented the annual movement of thousands
22:37
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
of animals.
22:37
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
Decades passed with several zebra
22:42
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
migrations blocked.
22:43
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
Then,
22:45
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
a few years ago,
22:46
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
the fences were removed.
22:48
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
And these migrations started up once more,
22:50
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
with the zebra using the exact same roots as in the past.
22:54
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
Despite the fact that no living zebra had ever made
22:59
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
that journey before.
23:03
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
This behaviour simply couldn't have been learned.
23:06
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
So how did they know where to go?
23:09
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
It's an extraordinary mystery and the subject
23:13
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
of some of the most recent animal behaviour research.
23:16
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
Scientists now believe that one aspect of the knowledge of
23:20
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
this route has been preserved in the genes of the zebra,
23:24
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
something previously thought impossible.
23:26
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
Elephants can respond to rain falling as far
23:30
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
as 280 kilometres away.
23:35
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
It's not yet certain how they do this,
23:37
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
but it's thought they might be able to detect the low frequency sounds
23:41
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
of the distant storms.
23:42
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
Although
23:47
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
zebra can't hear at such low frequencies as elephants,
23:50
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
perhaps they've evolved their own way of detecting distant storms,
23:54
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
timing their migration to coincide with rains that fall 250
23:58
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
kilometers away in Naipan.
24:00
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
But for now,
24:03
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
the chobie zebra are still staying put.
24:07
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
There have been a few local showers,
24:09
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
but something is stopping them from continuing their journey.
24:12
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
The data
24:17
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
from their collards show that they feed on the nutrient -rich grass in the
24:21
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
burnt, wooded area during the day,
24:23
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
and then travel back to the safety of the open plains at night.
24:27
S… Speaker 3 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
So
24:32
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
why has Socks not done the same?
24:34
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
Has she misread the cues?
24:36
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
Or did another as yet undiscovered factor spur her on?
24:42
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
It's becoming clear that the zebra's decision -making process is far
24:46
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
more complex than first thought.
24:48
S… Speaker 3 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
A
24:52
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
chance to check on socks comes at one of the fire breaks.
24:55
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
Swathes cut in the forest to stop fires spreading over large...
25:00
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
areas.
25:00
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
The caller data shows that Sox is due to cross one at
25:04
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
any moment.
25:05
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
It should give the team a chance to assess her condition and,
25:08
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
crucially, to see whether she's had her foal.
25:11
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
The
25:21
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
team only get a glimpse of Sox,
25:23
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
but it's enough.
25:24
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
90
25:29
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
kilometers from her destination,
25:30
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
they can confirm that she's alive and well and yet to give birth,
25:34
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
information the satellite data alone could never provide.
25:38
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
But it's also clear
25:42
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
that there are only three zebra.
25:44
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
Where is the rest of the family,
25:46
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
and in particular,
25:47
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
the stallion?
25:48
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
Without his protection,
25:52
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
these three are in even more danger of predation.
25:55
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
Soon,
26:05
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
after losing sight of Sox in the dense forest,
26:08
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
her collar suddenly stops sending GPS location updates.
26:12
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
Without this essential data,
26:15
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
there is little chance of finding Sox in this vast wilderness.
26:19
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
Her last known position is 40 kilometers
26:23
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
from Naipan.
26:30
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
The morning after the heavy rains,
26:32
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
the zebra start to arrive.
26:34
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
Janet's family is the first to be seen by the
26:39
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
team. She
26:43
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
was the first zebra ever recorded to make this migration,
26:46
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
and once again,
26:48
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
she's arrived just in time to enjoy the tender new grass shoots.
26:52
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
In
26:56
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
Chobe, Janet was part of a large family group of 15,
27:00
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
but now there seems to be only five.
27:06
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
Hopefully, the rest of her herd haven't succumbed to exhaustion or predation.
27:10
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
Soon,
27:18
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
all the other families are pouring into the park.
27:21
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
The
27:31
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
next collared female to arrive is Spirit.
27:33
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
She
27:39
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
was pregnant when she set off with the others.
27:41
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
We'll
27:46
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
never know what happened to that foal,
27:48
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
but it looks like her family have had a close call with predators.
27:52
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
Fresh wounds on three
27:56
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
of the zebra in this group are the unmistakable marks left by lions.
28:01
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
and one young foe looks to have had a very narrow escape.
28:05
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
Following
28:19
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
the failure of Soxa's GPS collar,
28:21
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
the team doesn't know if she's made it to Naipan or not.
28:24
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
But although the GPS part of her collar is no longer working,
28:28
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
it may still be transmitting a VHF radio signal.
28:32
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
On the ground,
28:35
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
its range is just a few kilometers,
28:37
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
but from the air,
28:38
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
it's more like 40,
28:40
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
which gives the team a chance to check if she's here
28:44
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
in Naipan.
28:47
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
Even so,
28:48
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
in an area of 15 ,000 square kilometers,
28:51
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
it's like looking for a needle in a haystack.
28:54
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
Eventually,
29:03
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
they do pick up a faint signal.
29:05
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
It's Sox.
29:07
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
After
29:12
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
flying in a search pattern,
29:13
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
they home in on her exact location.
29:16
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
Sox
29:25
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
has made it.
29:26
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
The
29:32
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
last time she was spotted,
29:34
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
she was traveling with just two other zebra.
29:36
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
Now
29:41
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
she's in a group of ten.
29:46
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
Socks appears to be in good condition and she's
29:55
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
in the company of a stallion.
29:57
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
But there is no sign of her having a foal.
30:00
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
Then something moves in the long grass.
30:04
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
Her
30:14
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
new foal is so small it must have been born in the last day
30:18
S… Speaker 1 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
or two.
30:18
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
Just in time for Socks to feed on the nutritious new grass and
30:23
S… Speaker 2 (Surviving Nature's Greatest Migrations - Elephants, Caribou & Zebras - BBC Earth)
provide it with the best possible milk.
