were found June 24, 1890, June 7, 1893, June 15, 1894, and June 24,

 Point, Long Island, August 11, 1905, and August 1, 1908 (Latham), 

 and at Charleston, S. C, by August 13 (Wayne). Most of the indi-

FRANKLIN'S GULL. Larus frariklini Richardson. 



'Range. — Interior of North America from Saskatchewan and Mani- 

 toba to the Gulf of Mexico, Middle America, and the western coast of 

 South America to Chile. 



Breeding range. — Franklin's gull is more strictly a bird of the inte- 

 rior than any other member of the genus. Its center of abundance 

 while breeding is in the marshy lakes of North Dakota, Manitoba, 

 and Saskatchewan. Here it breeds north to Lake Winnepegosis 

 (Macoun); Quill Lake, Saskatchewan (Barnes); and Many Island 

 Lake, Alberta (Bent). Birds have also been seen north to Hayes 

 River, Keewatin (Saunders); Cumberland House (MacFarlane); 

 Osier, Saskatchewan, May 2, 1893 (Colt); Flagstaff, Alberta, April 

 24, 1908, and May 4, 1909 (Buswell); and near Edmonton, Alberta, 

 May 11, 1907 (Preble). The species is so erratic in its choice of 

 nesting sites that there is no certainty that any of these latter records 

 represent breeding. 



This gull does not breed anywhere east of the Mississippi River, but 

 to the westward it is found south to Heron Lake, Minn. (Roberts); 

 Brookings, S. Dak. (Matheson); Pitrodie, S. Dak. (Cheney); Fort 

 Sisseton, S. Dak. (McChesney); and at Devils Lake, N. Dak. (East- 

 gate). During the years 1890 to 1893 it nested at Spirit Lake, Iowa 

 (Berry), but it probably does not breed anywhere in that State at the 

 present time. 



Winter range. — The species has been taken at Mazatlan, Sinaloa, 

 December (Lawrence); Chiapam, Guatemala, January, 1863 (Salvin); 

 and Panama, December 28, 1855 (specimen hi U. S. National Museum) ; 

 but the real winter home is on the coast of Peru and Chile, from Payta, 

 Peru (Saunders), to Concepcion, Chile (Philippi). 



Migration range. — During spring or fall migration Franklin's gull 

 has been taken at Laguna de S. Baltazar, Pucbla, September (Ferrari- 

 Perez)"; near the City of Mexico (Saunders); Zacatecas, August 

 (Saunders); Progreso, Yucatan, fall (Saunders); Port Limon, Costa 

 Rica (Cherrie); and the Galapagos (Snodgrass and Heller). It has 

 occurred accidentally at St. Bartholomew Island, Lesser Antilles
