The king eider (pronounced /ˈaɪ.dər/) (Somateria spectabilis) is a large sea duck 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.via:
