St. Lawrence, latitude 50°. In the same latitude at Crane Lake, 

 Saskatchewan, young were already out of the shell, June 9, 1894 

 (Spreadborough) . Young not yet able to fly were noted near Strater, 

 Mont., July 18, 1910 (Anthony"). 



Fall migration. — The first fall migrant of the species was noted at 

 Woods Hole, Mass., September 17, 1891 (Edwards); Wildwood, N. J., 

 September 7, 1895 (Stone); Pea Island, N. C, July 23 and August 

 20, 1904 (Bishop); Charleston, S. C, September 26, 1909 (McDer- 

 mid); Savannah, Ga., September 30, 1909, and common by October 

 6 (Perry); and Fernandina, Fla., July 13, 1906, next seen August 3, 

 and common September 16 (Worthington). It is evident that these 

 July records refer either to nonbreeding birds that have spent the 

 summer south of the regular summer home or to birds that having 

 lost their eggs or young have started early on their southward journey.

SHORT-BILLED GULL. Larus brachyrhtjnchus Richardson. 



Range. — Western North America from northwestern Mackenzie to 

 southern California. 



Breeding range. — The short-billed gull was originally described from 

 a specimen taken at Fort Franklin, Great Bear Lake, Mackenzie, May 

 23, 1826 (Richardson), from nearly the northern limit of its range, 

 the species breeding only a little farther north, to Fort Anderson 

 (MacFarlane). Thence it ranges in the breeding season west to Fort 

 Yukon (Dall) and the mouth of the Kowak River (Grinnell). The 

 principal summer homo of the species is in Alaska, where it breeds 

 west to Cape Lisburne (eggs in U. S. National Museum) ; Nelson Island 

 (Thayer) ; and Nushagak (eggs inU. S. National Museum) ; and south to 

 Morshovoi Bay (Littlejohn) ; Kodiak Island (U. S. National Museum) ;
