Breeding Range Map
The green area shows the predicted habitats for breeding only. The habitats were identified using 1991 satellite imagery, Breeding Bird Atlas (BBA), other datasets and experts throughout the state, as part of the Washington Gap Analysis Project. Habitats used during non-breeding months and migratory rest-stops were not mapped.

This species is locally common on rocky cliffs and offshore islets and inland waters. They may also be found nesting in the southernmost Puget Sound region.

Good habitats in the core areas of use included rock-cliff habitat in the Sitka Spruce and Puget Sound Douglas-fir zones along the waterways mentioned above.

Data are scarce from the BBA period for colonial nesting seabirds due to logistical problems of censusing offshore islands. Numerous smaller colonies exist throughout the area mentioned above. There have been reports of significant increases of this species on Protection Island from 1976-1984. There were also reports of an increase from 1200 to 2200 nests along the outer coast from 1985 to 1992 with populations fluctuating between 800-1200 nests.
