Smew

Mergellus albellus

A small merganser of northern Europe and Asia. A few turn up during migration and winter in the western Aleutian Islands, Alaska. Very rare elsewhere in Alaska. There are scattered records of birds wintering along the Pacific Coast south to California, and in the northeast; some of these may have been escapes from captivity.
