Crested penguin facts for kids
The term crested penguin is the common name given collectively to species of penguins of the genus Eudyptes. The exact number of species in the genus varies between four and seven depending, and a Chatham Islands species may have become extinct in the 19th century.
All are black and white penguins with yellow crests, red bills and eyes, and are found on Sub-antarctic islands in the world's southern oceans. All lay two eggs, but raise only one young per breeding season; the first egg laid is substantially smaller than the second.
Mitochondrial and nuclear DNA evidence suggests that the crested penguins split from the ancestors of their closest living relative, the yellow-eyed penguin, in the mid-Miocene around 15 million years ago, before splitting into separate species around 8 million years ago.
The crested penguins are all similar in appearance, having sharply delineated black and white plumage with red beaks and prominent yellow crests. Their calls are more complex than those of other species, with several phrases of differing lengths. The royal penguin (mostly) has a white face, while other species have black faces.
Crested penguins breed on Sub-antarctic islands in the southern reaches of the world's oceans; the greatest diversity occurring around New Zealand and surrounding islands. Their breeding displays and behaviours are generally more complex than other penguin species. Both male and female parents take shifts incubating eggs and young.
