The King eider (Somateria spectabilis), is a large species of eider that breeds along Northern Hemisphere Arctic coasts of northeast Europe, North America and Asia. The birds spend most of the year in coastal marine ecosystems at high latitudes, and migrate to Arctic tundra to breed in June and July. They lay four to seven eggs in a scrape on the ground lined with grass and down. This species is smaller than the common eider. The male is unmistakable with its black body, white breast and multicoloured head. The drake's call is a deep cooing, and hens give various croaks and quacks.
