King Eider

The King Eider, conspicuous for the male’s elegant plumage, is a common nester on the Arctic Coastal Plain of Alaska. King Eiders typically nest in wet lowland tundra with many small ponds and pools, islands, and wet marshes. Dry tundra is also used when small lakes and ponds are available nearby as foraging areas (Powell and Suydam 2012). Unlike other eiders, this species is not as closely tied to coastal breeding habitats. During the breeding season, their diet is primarily omnivorous (Powell and Suydam 2012). Alaskan breeders spend their winters in marine environments mostly in the Bering Sea and along the Aleutians (Powell and Suydam 2012). Eider populations have declined since the 1970s (Powell and Suydam 2012). Current Arctic Coastal Plain population is estimated at approximately 15,000 (Larned et al. 2005).
