The colonies are empty throughout the winter, but adult Adélie penguins begin to arrive in October, when the Southern Hemisphere spring commences. The male arrives first, making a simple nest, and the female then settles on the nest, laying a pair of eggs. Both parents incubate them for about 35 days. The young grow up in crèches, and by March, the colony is deserted once again, as adults and young head out to sea.
