The Washington Gap Analysis Project created breeding bird maps only. The non-breeding birds (e.g., wintering, pelagic (coastal), and birds expanding their ranges) are represented only by NatureMapping sightings.
NatureMapping observations reported by townships throughout the year.
The Greater Scaup is seen in Washington in winter only. It is commonly found on large open lakes and bays. It migrates and winters in small or large flocks from the coastal areas of southern Alaska and British Columbia down through California, often with Lesser Scaups. This species nests in central Alaska.Text edited by Gussie Litwer
