It 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. They migrate to the [[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. The king eider [[bird migration|winters]] in arctic and subarctic marine areas, most notably in the Bering Sea, the west coast of Greenland, eastern [[Canada]] and northern [[Norway]]. It also happens yearly off the northeastern [[United States]], [[Scotland]] and [[Kamchatka Peninsula|Kamchatka]]. Breeding areas include the [[Arctic coastal tundra]] of the north coast of [[Alaska]]. This species dives for [[Benthic zone|benthic]] invertebrates, such as [[crustacean]]s, [[polychaete]] worms, and [[mollusc]]s, with [[mussel]]s being a favoured food. Wintering birds can form large flocks on suitable coastal waters, with some flocks bigger than 100,000 birds.
