666. Audubon's Warbler. 



Deiidroica auduboni (Towns.) Baird. 1858. 



This warbler was only observed in the Rocky Mountains beyond 

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

 Observed a pair near Calgary June 22nd, 1897, in the foot- 

 hills from there to Crow's 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's Bridge, B.C., in May, 

 1889, but common at Hastings and Agassiz, in the Fraser valley; 

 only one individual seen at Chilliwack in May, 1903, but were com- 

 mon at Huntington, on the International Boundary, in September, 

 1902; 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. {Spreadborotigh.) British Columbia. {Lord.) Abun- 

 dant spring and fall migrant. I think a few breed in the coast 

 region; it is very common on Vancouver Island. {Streator.) Very 

 abundant summer resident all over the province. {Fannin.) A 

 common summer resident at Chilliwack; a few remain until Janu- 

 ary. Tolerably common breeder at 158-Mile House, B.C. 

 {Brooks.) Abundant summer resident everywhere in British 

 Columbia. {Rhoads.) Found nesting at Donald, Agassiz and 

 Vancouver, B.C. in 1894. (£. 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's Lake, 14 

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