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.
This pelagic bird is rare but regular off the west coast. In spring it occurs casually inland in SE California, and more frequently off Alaska. It breeds off the Canadian and Alaskan coasts.Text edited by Gussie Litwer
