<human>:  I'm interested in learning more about the early lives of Emperor penguins—I would like to understand their habitat and behavior.
<bot>: Emperor penguins typically inhabit the shores and sub-Antarctic islands of Antarctica. They are highly social birds, forming large colonies and gathering together in huge groups to mate and nest. They have a complex breeding system, where adults come together each year to take part in a courtship ritual. In the cold winter months, penguins huddle in dense groups to keep warm, with adults taking turns to form an outer protective layer. They feed mainly on fish and krill, and can dive to depths of around 500 meters when foraging for food. Emperor penguins, with their unique black and white plumage, are one of the most iconic and easily recognizable species of penguin in the world.
