Steller's Eider Polysticta stelleri
The species occurs annually in a very limited number around the year. Usually, the species occurs individually together with eider ducks, but groups of up to ten individuals are registered. A number of winter observations (together with Common Eiders) are recorded. The species is seen in pairs (courting) with Common Eiders, without hybridisation being registered. Breeding attempts are suspected some years.
