Assa.; they were common by the gth, but were all gone by the 

 15th. On June 24th of the same year they were common in all 

 the brush on the east end of the Cypress Hills and were certainly 

 breeding. First seen at Edmonton, Alta., May 7th, 1897 ; none 

 seen after the 9th. All were migrants. {Spreadborough.) First 

 noticed in numbers at Prince Albert, Sask., last spring (1899). 

 Probably common but irregular in its visits. {Coubeaux.) This 

 species is a northern bird and breeds.in all parts of the Northwest 

 Territories, arriving about the middle of May and leaving early 

 in September. {Richardson.) North to Fort Resolution on Great

554a. Gambel's Sparrow. 



Zonotrichia leucophrys gambelii Ridgw. 1899. 



I was surprised to ' find that the white-crowned sparrows of the 

 Mouse (Souris) River were the variety instead of typical leuco- 

 phrys, but such was the case, as shown beyond question by some 

 of the specimens taken with perfect head-dress ; found also in 

 the Rocky Mountains in the autumn where they possibly breed. 

 {Coues.) North to Lapierre's House on the Mackenzie River. 

 {Ross.) • This was common as a migrant at Indian Head in 

 1892, and at Medicine Hat, Assa., in May, 1894. About forty 

 miles southwest of Calgary this species was rather common. 

 A nest was taken June 28th having five fresh eggs, placed 

 at the root of a clump of willows ; on Moose Mountain, at 

 6,000 feet altitude, found a nest with six fresh eggs, the 

 same day another nest was taken at 7,500 feet, containing three 

 young and two eggs; common in the 'foothills from Calgary 

 south to Crow's Nest Pass ; common from Prairie Creek, Alta.,
