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.

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.) I am positive I have often heard the song of this species at 

 Bennett, June i7th-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
