Smith, October 4. While ascending the Athabaska, we observed 

 the bird as follows: Near Grand Rapid, October 24; above 

 House River, October 25; near Pelican Rapid, October 26 and 

 27, and below Iron Point, October 28. It was noted also be- 

 tween Athabaska Landing and Edmonton on November 2 and 3. 



Penihestes hudsonicus hudsonicus (Forster). Hudsonian Chick- 

 adee. 



We did not note this chickadee during our northward journey, 

 but while on our return trip found it common on several occa- 

 sions. A number were seen on Caribou Island on September 

 21, and others near Stone Island, east of Fort Resolution, on 

 September 25. A band of about a dozen were observed on the 

 Point Ennuyeux Portage on September 30. In response to 

 Seton's low whistling they came very close and responded with 

 a low lisping note but would not whistle in response. We noted 

 the bird later as follows: Slave River, below Point Brule", Octo- 

 ber 1 ; near Salt River, October 3 and 4, and Athabaska River, 

 near Poplar Point, October 13. 



Hylotichla alicice alicios (Baird). Gray-cheeked Thrush. 



The gray-cheeked thrush was observed in migration on the 

 Athabaska at Grand Rapid, May 24. We next observed the 

 bird on its breeding grounds among the islands in the eastern 

 part of Great Slave Lake, noting it as follows: Caribou Island, 

 July 20; near The Narrows, July 22, and near Mountain Port- 

 age, July 23. We noted the bird also on Pike's Portage between 

 the eastern end of Great Slave Lake and Artillery Lake on July 

 28, 29, 30, and 31. We next observed the species near the same 

 point on September 11, and we saw one, the last recorded for 

 the season, at Fort Reliance on September 14. 



Hylocichla ustulata swainsoni (Tschudi) . Olive-backed Thrush. 



This is the commonest thrush in the Athabaska region. We 



first noted it already in full song on the Athabaska, near Fort 



McMurray, on May 28, and we next saw it below Fort McKay
