on the lower part of Slave River in late September during our 

 southward trip. 



Bombycilla garrula (Linn.). Bohemian Waxwing. 



This interesting species was first observed near the mouth of 

 Salt River on June 27, when a nest containing six eggs was col- 

 lected. The nest resembled closely that of the cedar waxwing, 

 but was larger and more compact. It was settled on the hori- 

 zontal limb of a Banksian Pine {Pinus divaricata). The eggs 

 were in varying stages from fresh to advanced incubation. 

 While descending Little Buffalo River on July 12, we saw a 

 small company of these birds leisurely flycatching. The species 

 was next seen on October 18, while we were ascending the Atha- 

 baska, a small flock being observed. Others were seen above 

 Boiler Rapid on October 22. We last noted the bird on Novem- 

 ber 2, a few miles south of Athabaska Landing, a flock contain- 

 ing thirty or forty individuals. 



Lanius borealis Vieillot. Northern Shrike. 



This bloodthirsty species was first noted at Fort Reliance on 

 September 15, when one in brownish plumage, evidently a bird 

 of the year, was seen in close pursuit of a tree sparrow. The 

 shrike was collected. The species was elsewhere observed as 

 follows: Slave River, near Point Ennuyeux, September 30; 

 Smith Landing, October 5 (when we saw one in pursuit of a 

 rusty grackle); Athabaska River, near Fort McKay, October 

 14; below Iron Point, October 28; near Calling River, October 

 29, and on the road south of Edmonton on November 3, when 

 two were observed. 



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



The red-eyed vireo was common at Fort Smith, where it was 

 observed at various times, June 13 to 24, and again, June 28 to 

 July 4. Other points and dates of observation were as follows: 

 Mouth of Salt River, June 25; west of the same point, June 24
