About
Steller's eider is a migratory Arctic sea duck that breeds along the coastlines of Russia and Alaska, as well as in the Baltic Sea. It is the smallest, and fastest flying of the duck species known as eiders; it is closely related to the other species of eider in the genus Somateria, but sufficiently distinct to be given separate recognition as the only member of the genus Polysticta.
Fun Fact
