CALIFORNIA GULL. Larus californicus Lawbence. 



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);

 (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
