The Macaroni Penguin inhabits the regions stretching from the Antarctic Peninsula to the Subantarctic. Their bright yellow crest and feather plumage make this species easily recognizable. Both sexes share a similar appearance. Adults typically reach 28 inches (71 cm) in length and weigh up to 12.1 lbs. (5.5 kg). At five years old, females reach sexual maturity, while males fully mature at six years. Breeding season begins in late October. Nests are fashioned out of a depression in the ground and lined with grass or small stones. Females lay a clutch of two eggs in early November. Males and females take turns incubating the first egg. Upon the arrival of the second egg, the female leaves and returns after the chick has hatched. As a somewhat monogamous animal, about 75 per cent of pairs will mate the following year.
