460 NORTH AMERICAN FAUNA. Tno. 27. 



River, October 6; and below Roche Trempe-l'eau, October 8. After 

 reaching- Fort Simpson I saw the bird but once, noting one on No- 

 vember 5. 



In 1904 I saw one at Fort Simpson on April 16. Two specimens 

 in the museum at that place were taken some years ago at Fort Rae. 



Ross recorded the northern shrike as not rare in the Mackenzie 

 River region north to Fort Good Hope, and as having been taken at 

 Fort Simpson. MacFarlane found it breeding in the Anderson 

 River country, and obtained a nest containing six eggs at Fort Ander- 

 son, June 11, 18G3, and another on Anderson River to the northward 

 of the post." Baird recorded specimens from Fort Resolution, Fort 

 Rae, Fort Simpson, Peel River, and Fort Liard. 7 ' Seton records the 

 species from Fort Reliance/ 



In the autumn of 1896, J. Alden Loring observed several individ- 

 uals of this species near Baptiste River, between Jasper House and 

 Smoky River. The stomach of one killed there September 30 was 

 filled with blueberries. He saw several also on the trail between 

 Jasper House and Edmonton later in the autumn. 



Lanius ludovicianus excubitorides (Swains.). White-rumped Shrike. 

 Spreadborough observed a pair at Edmonton, Alberta, May 18, 

 1897, engaged in building a nest.'' The species seems to be rather 

 common on the plains of the lower Saskatchewan, from which region 

 it was first described. 



Vireosylva olivacea (Linn.). Red-eyed Vireo. 



This persistent songster is a common summer inhabitant through- 

 out the region north to Great Slave Lake and the upper Mackenzie, 

 and during June and July its cheerful strain continually greets the 

 traveler as he journeys along the streams. 



In 1901 we first noted this vireo at our camp near Point La Brie, 

 12 miles northeast of Fort Chipewyan, May 27, and collected a pair 

 at the same place May 29. We found it common near the outlet of 

 Athabaska Lake, June 1 to 4, and saw or heard it almost daily along 

 our route between that point and Fort Smith, June 5 to 18. We 

 saw a few at Fort Smith, June 19 to 28, and collected a specimen 

 June 25. While we were descending lower Slave River, we noted it 

 at points just below Fort Smith, June 29; 75 miles below, July 1; 

 and near the mouth of the river, July 4. I observed it at Fort Reso- 

 lution, July 7 and 8, and Alfred E. Preble noted it there on July 22. 

 While we were ascending the Athabaska we heard one singing a 

 short distance below Grand Rapid on August 20.
