Taxonomic Comments
Closely related to other species within the Larus californicus complex; this complex poses one of the most complicated problems in ornithological systematics today. Hybridizes with L. occidentalis in southern British Columbia to western Oregon, withL. argentatus (on a limited basis) in south-coastal and southeastern Alaska, and with L. schistisagus in Kamchatka (AOU 1998).

Range Extent Comments
BREEDS: coastally from Alaska and islands of St. Lawrence, Pribilofs, Aleutians south to northwestern Oregon and Commander Islands. WINTERS: southeastern Alaska south along Pacific coast to southern Baja California; in Asia, Bering Islands to Japan; fairly frequent in northwestern Hawaii; casually inland in Alberta, Idaho, western Arizona, Manitoba, and Oklahoma; regular in southern Nevada (Lake Mead); recently reported from Utah (Fischer 1988).
Ecology & Habitat

Habitat

Coastal waters; shores, cliffs, rock ledges, grassy slopes, beaches, harbors of coastal cities, dumps. Nests coastally, on cliffs, rocks, grassy slopes, mostly on offshore rocks and islands; preference for sandbar islands, flat tops of rugged islands, or beaches. On estuarine islands in Washington and Oregon, nesting concentrated in areas where driftwood scattered throughout grass-forb communities (Spendelow and Patton 1988); among colonies of other seabirds.

Ecology

Washington and British Columbia: first-year survival was lowest September-November; survival rate was 61, 80, and 85% for first year, 2nd year, and adults, respectively (Reid 1988).

Reproduction

Usually a clutch of 2-3 eggs is laid from late May into July; mean laying date is around 1st of June in western Gulf of Alaska. Incubation lasts 26-29 days. Reproductive success varies with food availability/quality (Murphy et al. 1984). Young depart nest at 40-45 days, can fly at 35-54 days, according to various reports. In Washington and British Columbia, age of first reproduction was 4-7 years in both sexes; most individuals had same mate in successive years (Reid 1988). Nests in large or small colonies; up to several thousand birds in Washington colonies (Spendelow and Patton 1988).
