0:01
These are crowned lemurs.
0:13
They don't live up here,
0:15
but they must cross the peaks to find fruiting trees
0:18
in the forest pockets.
0:53
Exposed to the tropical sun,
0:56
it's devilishly hot.
1:12
The group seeks shelter and a brief respite.
1:27
The lemurs are vulnerable here
1:29
and need to get a move on.
1:48
There's still a way to go before they reach the forest.
2:06
They get to what looks like
2:08
the most daunting part of the journey.
2:10
A 30-metre drop where the limestone has fallen away
2:14
to create sheer cliffs.
2:19
But crowned lemurs are as good at rock climbing
2:22
as they are at tree climbing.
2:39
Once down, they'll find shelter from the heat and plenty to eat.
2:44
But they must be on their guard.
2:53
There is one danger that every lemur on the island fears.
2:57
A hunter that climbs as well as they can.
3:00
The fossa.
3:04
No big African predators made it to Madagascar.
3:07
There are no lions, no leopards, no wild dogs.
3:11
Instead, the island's top predator is a giant mongoose.
3:17
And it eats lemurs.
3:24
But it has more curious habits.
3:28
It's the mating season,
3:30
and this female has stationed herself 15 metres up a tree.
3:34
She's chosen a branch that will just support her own weight,
3:38
plus that of a male.
3:46
A male approaches.
3:47
If she approves of him, she'll allow him to mate.
3:50
If she doesn't, she'll back away to a thinner branch
3:53
and he won't be able to get to her.
4:00
She's only fertile for a few days a year,
4:03
so setting herself up in this tall tree
4:06
is a good way of advertising her availability to suitors.
4:11
And it seems to work.
4:14
This is the sixth male she's entertained today.
