Observasjonsdetaljer

An adult male. They are uncommon visitors to California from breeding grounds in Alaska and Western Canada. In comparison with the more familiar Common Goldeneye, male Barrow's has a steeper forehead, smaller bill, a tear-drop shaped white crescent between the bill and eye and more dark on the scapulars with white spots surrounded by black forming a "piano key" pattern. Even though breeding populations are widely separated, no geographic variation has been found.
