General

Crested Auklet: Small, oddly attired seabird of Arctic waters with dark gray body. Head has a strange, smiling orange bill, quail-like crest, bright yellow-white eyes and white eye plumes. Sexes are similar. Winter adult has reduced dingy orange bill and smaller crest. Juvenile lacks crest and has dark gray-orange bill.

Range and Habitat

Crested Auklet: Breeds in the Aleutians and other islands and coasts around Bering Sea and coastal portions of Alaska. Spends winters in nearby ocean waters and nests on island coasts where sliding rocks form a talus slope, with the largest boulders at the bottom and bare cliff at the top, near the sea for feeding.

Breeding and Nesting

Crested Auklet: Lays a single white egg on a coastal or island cliff, with no nest materials added; usually nests in colonies. Incubation ranges from 29 to 41 days and is carried out by both parents.

Foraging and Feeding

Crested Auklet: Feeds on small crustaceans and plankton; forages by diving from the surface.

Vocalization

Crested Auklet: Usually silent, but honks and grunts on breeding grounds.
