By August the warmer temperatures allow now the colony to break up.
-
Winter has taken its toll
-
and the males have lost half their body weight
-
They're also left holding the baby.
-
These newly hatched chicks can expect very little from their fathers.
-
After four months of fasting, there's nothing solid in a male's stomach,
-
but he is able to produce a protein-rich secretion.
-
but that is barely enough to keep a chick alive for a week.
-
Fattened up from two months fishing,
-
the females reappear with magically accurate timing.
-
In such a crowd, calling is the best way to locate a partner.
-
A female arrives to take over.
-
At first, the male is a little reluctant to abandon his offspring.
-
Once the exchange starts, it needs to be quick.
-
A few minutes on the ice would almost certainly kill the chick.
-
Now at last, the chick can feed properly.
-
During the next five months,
-
an emperor chick will eat 100 kilos of food.
-
In one big helping it can eat a third of its own bodyweight.
-
Now at last their fathers have a chance to eat,
-
but the ice edge may be several hundred kilometres away.
-
Emperor penguins have a faster mode of transport than just plain walking.
-
They can toboggan.
-
From now on males and females will take turns to go fishing.
-
Each trip may involve travelling thousands of kilometres, in search of food.
