冰雪世界 8

Driven by hunger,

the exhausted females now return to the ocean on their own

repeating the epic journey they made with the males only a month before

Now the sun barely appears above the horizon

As the days shorten,

its warmth is withdrawn from the continent

With the females gone

the colony undergoes a strange transformation

The males shuffle into groups,

their eggs still tucked away above their feet

They lock together in tightly packed huddles

as they struggle to keep warm

Speeding up the action

reveals how these huddles constantly shift and change

as each penguin works its way towards the warmer interior

Crammed into this scrum,

the birds are remarkably good natured,

but they have to be

If the huddle breaks even for a moment,

precious heat escapes
