About Common Eider

The common eider is one of Iceland’s most important and well-known seabirds. It inhabits coastal areas and islands where it breeds in large colonies. The species is famous for its soft down, which has been harvested for centuries.

Its diet consists mainly of shellfish and crustaceans. Common eiders dive for food in shallow coastal waters. They are an integral part of Iceland’s coastal culture.
