Adélie Penguin Chicks, Torgersen Island, Antarctica
Penguin chicks grow up fast. They get so big their parents can't feed them enough one at a time; both need to go fishing daily. In order for the chicks to have some protection while their parents are out at sea, they gather in groups, called a "creche". While the parents are away, the creche is guarded from predators such as skuas and giant petrels by a few non-breeding adult penguins.
