Scientific Name: Polysticta stelleri
Steller’s Eider was named for the 18th-century German zoologist and explorer George W. Steller. This is the smallest and swiftest-flying of the eiders. Steller’s Eider has a varied diet, including crowberries- a common berry of the Arctic tundra. The male, in a manner somewhat unusual for ducks, stays with the hen until incubation has begun.
Males are largely black and white above and pale tan below with a black eye patch, a green-and-black nape crest, and a black collar. Females are mottled dark brown. Both sexes have a blue speculem bordered with white.
Breeds on the eastern Arctic coast of Alaska and south to St. Lawrence Island and the Yukon-Kuskokwim deltas; winters along the southwestern Alaskan coast and the Aleutian Islands, and casually south to the northern California coast.
