1908.] BIRDS. 465 



morning of May 31. It was next noted at Smith Landing, June 11 ; 

 was rather common on Smith Portage, June 13; and was observed on 

 the lower Slave, June 19. A specimen was taken at Fort Resolution, 

 June 22, and several individuals were observed there on June 24. 

 My brother and Gary heard a few in poplar woods at Fort Provi- 

 dence, July 7 and 8, and saw numbers in alder thickets on the upper 

 slopes of the Xahanni Mountains on July 15. On their return trip 

 they saw several birds at Fort MeMurray, August 9 and 10, and near 

 Quito River, August 28. During my trip northward from Fort Rae, 

 after the division of the party, I saw one on Lake Hardisty, August 16, 



In the spring of 1901 I noted the first individuals at Fort Simp- 

 son on May 21, taking two females. I saw a single bird at Fort Nor- 

 man, June 12 ; and on my return trip saw one near the mouth of 

 Nahanni River, July 24. 



Baird recorded specimens from Fort Simpson and Fort Resolu- 

 tion, the latter taken May 22, 1800, by Kennicott." Baird, Brewer, 

 and Ridgway describe nests and eggs from Great Slave Lake, and 

 state that the species was found breeding near Fort Resolution, and 

 at Fort Rae and Fort Anderson/' In the latter region MacFarlane 

 considered it one of the rarest of the warblers, but found several 

 nests.' Macoun, on the authority of Raine, records a nest found at 

 Peel River, June 18, 1900, by C. E. Whittaker; and under the name 

 H. c. lutesccns, records specimens taken at Edmonton/' 



J. Alden Loring reported this species common in poplars along 

 streams in the mountains north of Jasper House in August, 1896, 

 " until a severe snowstorm in the latter part of August sent them 

 all south." He took a specimen, now in the Biological Survey collec- 

 tion, at the head of Grand Cache River, Alberta, on August 31. 



The breeding birds of w r estern Alberta are referable to the form 

 described as Vermivora c. orestera. e The typical form, however, 

 occurs in the same region in migration. 



Helminthophila peregrina (Wils.). Tennessee "Warbler. 



This species breeds abundantly throughout the region north to 

 Great Slave Lake and the upper Mackenzie. In 1901 it was first de- 

 tected near Fort Chipewyan, where a specimen was taken June 1. 

 Another was shot on a wooded island near the outlet of Athabaska 

 Lake, June 2, and others were collected 10 miles below Peace River, 

 June 10, and at Smith Landing, June 17. At Fort Smith the species
