Spectacled Eider
Currently, spectacled eiders occur along the coast of Alaska and easternmost Russia and into the Bering Sea. There are two breeding populations in Alaska and one in Russia. Historically there were more breeding individuals in Alaska but more recently the Russian population is much larger. Currently the United States population is an estimated 3,000-4,000 nesting pairs
The spectacled eider molts at sea anywhere from 2 to 45 kilometers from the shore and north of 63°N. Since they are rarely seen outside of their breeding grounds, their wintering grounds in the Bering Sea were not known until recently with the help of satellite telemetry in 1995
