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 Buller's Shearwater is one of the species.
NatureMapping observations reported by townships throughout the year.
This shearwater is most common off the coasts of Washington to Central California. It makes rare appearances north and south along the west coast. It breeds on islands off New Zealand. It was formerly called the New Zealand Shearwater.Text edited by Gussie Litwer
