656. Audubon Warbler. 



Dendroica auduboni auduhoni (Towns.) Sclater. 1858. 



This warbler was only obser^^ed in the Rocky mountains beyond 

 the eastern foothills of which it is not known to extend. {Coues.) 

 Mr. Eastgate shot a female in a grove of pines in the Cypress hills, 

 Sask., in 1906. {A. C. Bent.) Observed a pair near Calgary, June 

 22nd, 1897, in the foothills from there to Crow Nest pass in July and 

 August; observed a few in the valley of the McLennan, B.C. in July, 

 1898; common at Banff, Rocky mountains, in the summer of 1891, 

 building their nests in tall spruce trees; quite plentiful at Revel- 

 stoke, B.C., on the Columbia river, and down that stream to Deer 

 park and Robson in June, 1890; young full grown by June 24th; 

 arrived at Revelstoke on April 12th, 1890; common and breeding 

 at Trail, on the International Boundary, in June, 1902; first seen 

 April 13th, 1903, at Penticton, B.C., after this date they became 

 common; rather rare at Spence Bridge, B.C., in May, 1889, but 

 common at Hastings and Agassiz, in the Eraser valley; common 

 nearly everywhere along the International Boundary from Eernie 

 west to Douglas, B.C., in 1902-6; common around Victoria early in 

 May, 1893, but the bulk of them had left by the loth, only a few 

 remained to breed ; during the latter part of April and first half of 

 May this bird is common in most parts of Vancouver island, but 

 later they are very scarce. (Spreadborough.) British Columbia. 

 (Lord.) Abundant spring and fall migrant. I think a few breed in 

 the coast region; it is very common on Vancouver island. (Sfrcat- 

 or.) Very abundant summer resident all over the province. (Fan- 

 nin.) A common summer resident at Chilliwack; a few remain 

 until January. Tolerably common breeder at 150-Mile House, B.C. 

 (Brooks.) Abundant summer resident everywhere in British 

 Columbia. (R)wads.) Eound nesting at Donald, Agassiz and 

 Vancouver, B.C. in 1894. (E. F. G. White.) 



Breeding Notes. — At Banff, in the Rocky mountains, on June 

 14th, 1893, I found a nest containing four eggs of this species. It 

 was built in a willow about five feet above the water on the shore 

 of Vermilion lake. Mr. Dippie found its nest at Devil lake, fourteen 

 miles from Banff, June 22nd, 1902. (W. Raine.)
