Steller's eider (Polysticta stelleri) is a migratory duck species found along the areas of the Arctic coast. It feeds on crustaceans, molluscs and other marine and freshwater invertebrates.

The other subspecies is endemic to areas of southern Africa. It feeds on fish, small mammals, young birds, amphibians, insects and crustaceans. Although it is classified as least concern, global populations are slowly declining.
