CATALOGUE OF CANADIAN BIRDS. 627 
(Garneau.) This bird builds a neat and compact nest and generally 
places it high up on the willows or in the forks of a small tree, rose 
bushes or wolf willow. It is chiefly composed of dead leaves of 
grasses and carices, and with a thick lining inside of small feathers, 
hairs and fine cottony wool gathered from the catkins of willows; 
numerous nests of the above character were found in June, 1895, 
in southern Saskatchewan by the writer.

(Spreadborough.) 
Alaska in general, both along the coast and throughout the in- 
terior; and southwest to Vancouver island, migrating southward in 
winter to California. (Ridgway.) This is perhaps the most abun- 
dant warbler in Alaska. It is found everywhere in the wooded 
interior. (Nelson.) Specimens of this species were obtained from 
several localities. It is common at many points on the Yukon 
river. (Turner.) A single adult male taken June 23rd at Sitka, 
Alaska; and a few others heard previously in the dense firs along 
Indian river were all noted on this occasion. Yellow warblers, 
mostly in immature plumage were observed commonly in the Kowak 
valley, Kotzebue sound, Alaska, in the latter part of August. (Grin- 
nell.) Jam positive I have often heard the song of this species at 
Bennett, June 17th-22nd. I took an adult male at Cariboo Crossing 
June 27th, and heard the song at Lake Marsh. An adult female 
was taken by Osgood near the Nordenskiold river July 22nd and 
family parties were often found in the alders and willow thickets
