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.
The Washington Gap Analysis Project could not find any historical research records (i.e., Breeding Bird Atlas, Breeding Bird Survey, Bird Banding and Recovery) for 73 species of birds. The Pink-footed Shearwater is one of the species.
NatureMapping observations reported by townships throughout the year.
During the summer this shearwater winters in the North-Pacific, far offshore from Baja, California and Oregon. It is common late spring through fall but rare throughout the rest of the year. It breeds on islands off Chile. In Washington, it is a fairly common to common pelagic visitor, May to October. It is rare in winter.Text edited by Gussie Litwer
