NOKTH AMERICAN FAUNA. 



[NO. 27. 



willow thickets in low grounds and along streams in June, 1898. * * * 

 ( Spreadborough.) One of the most abundant birds between Athabasca Land- 

 ing and Lesser Slave River ; first noted May 30 ; common down the Athabasca 

 River to Fort McMurray, lat. 56° 40' ; common up the Clearwater River and at 

 the north end of Methye Portage ; common between Methye Lake and Isle a la 

 Crosse Lake; last seen August 10. (J. M. Macoun [1888]. 



Seton records the species from near the eastern end of Great Slave 

 Lake, where one was seen July 28, 1907. 



J. Alden Loring took a female at Banff, Alberta, August 27, 1894, 

 and a male on the Blueberry Hills, on the Jasper House trail about 

 100 miles w^est of Edmonton, May 27, 1896. MacFarlane, in a manu- 

 script list, records a specimen taken near Fort Providence, May 18, 

 1885. 



Bendroica tigrina (Gmel.). Cape May Warbler. 



During our investigations we detected this species at but two lo- 

 calities, taking a female at Point La Brie, near Fort Chipewyan, May 

 29, 1901, and a male beside Slave River 50 miles below Fort Smith, on 

 June 30 of the same year. In a small collection recently received is 

 a fine male, taken by H. W. Jones at Fort Simpson, May 23, 1905, ex- 

 tending the known range of the species to the upper Mackenzie. 

 The only previous record from the region seems to be that of Russell, 

 who took a male, the only example observed, at Fort Chipewyan, 

 May 31, 1893.« 



Bendroica aestiva (Gmel.). Yellow Warbler. 



"MiG familiar yellow warbler breeds in suitable places over the en- 

 tire region north to the limit of the forest. In 1901 it was first noted 

 on the lower Athabaska, May 17, when a single bird was seen in the 

 Avillows bordering the river. A number were seen in willow thickets 

 near Fort Chipewyan, May 24, and one was taken near there June 1. 

 It was next noted at Fort Smith, where it was seen almost daily, June 

 19 to 28, but was not common. A nest containing nearly fledged 

 young was found in a low bush Jime 22, and an adult male was taken 

 June 26. At Fort Resolution the species was observed by myself on 

 July 6 and 9, and by Alfred E. Preble on July 10 and 14. Old and 

 young birds were several times seen at Fort Rae, July 19 to 29, and 2 

 specimens were taken there on July 29. While we were ascending the 

 Athabaska, several were seen at Big Cascade Rapid. 



In the spring of 1903 we first observed this common warbler a few 

 miles above Pelican Rapid, May 18. We next noted it 50 miles below 

 Fort McMurray, May 29, and found it common on the lower Atha- 

 baska, May 30 to June 1. We saw it frequently also at Fort Chipe-
