CALIFORNIA GULL,. Larus californicus Lawrence. 
Range. — Western North America from the lower Anderson River, 
Mackenzie, to Oaxaca, Mexico. 
Breeding range. — The California gull breeds throughout a great 
extent of latitude, but in this wide range the nest has been found at 
only a few places: Fort Anderson and the lower Anderson River, 
Mackenzie (MacFarlane), though probably rare, if anything more 
than casual, so far north; Great Slave Lake from Fort Resolution to 
Fort Rae (eggs in U. S. National Museum); Big Stick Lake and Crane 
Lake, Saskatchewan (Bent); Stump Lake, N. Dak. (Eastgate); Devils 
Lake, N. Dak., common (Job and Bishop) ; Great Salt Lake (Ridgway) ; 
Utah Lake (Goodwin); Malheur Lake and Lower Klamath Lake, 
Oreg. (Finley); Pyramid Lake and Soda Lake, Nev. (Ridgway); 
Clear Lake, Cal. (Finley); Eagle Lake, Cal. (Townsend), and Mono 
Lake, Cal. (Brewster). 
Winter range. — The principal winter home of the California gull is 
along the coast of the State from which it derives its name and north 
to Portland, Oreg. (Anthony). A few remain in winter on Great 
Salt Lake (Goodwin), and the species ranges south at this season to 
the coast of Lower California, being common even as far south as 
La Paz (Bryant). Thence it has occurred at Rio de Coahuayana, 
Colima (Brewster); Manzanillo, Colima (Nelson); Alvarado, Vera 
Cruz (Ferrari-Perez); and San Mateo, Oaxaca, February, 1869 
(Sumichrast). It is also fairly common in winter at the head of the 
Gulf of California (Rhoads), and inland to the Salton Sea, Cal. (Grin- 
nell) and to Owens Lake, Cal. (Fisher). 
Migration range. — Outside the usual breeding and winter ranges 
the California gull has been taken at Fort Simpson, Mackenzie (speci- 
men in U. S. National Museum) ; Many Island Lake, Alberta, June 18 to 
July 13, 1906 (Bishop); Reno County, Kans., October 20, 1880 (Goss); 
Galveston, Tex. (Singley); Laredo, Tex., October 16, 1866 (specimen 
in U. S. National Museum); Denver, Colo., October 26, 1878 (Carter);

(Osburn); Larimer County, Colo., April 18, 1894 (Breninger); Hawaii, 
once (Bryan); British Columbia, on the coast north to Cormorant 
Island, May 24, 1911 (Wetmore); and at Hot Springs, Atlin, British 
Columbia, July 16, 1914 (Kermode).
