borough.) This seems to be the form that breeds in southern British 

 Columbia, where I have noticed it in summer as far east as Arrow 

 lakes, Columbia- river, in lat. 50°. (Brooks.) I found this form 

 very common at Skidegate, Queen Charlotte islands, in August, 

 1895. (Kermode.) Mr. Frobese shot an immature male on August 

 5th, 1897, at Sitka, and others were seen after that date. (Grinnell.) 

 This species was seen in the mountains about Ilianana pass, and 

 daily at the mouth of the Chulitna river, and others were seen at 

 Nushagak in 1902. Frequently seen at Tyonek, Cook inlet, Alaska. 

 (Osgood.) One immature male at Sheep creek, Alaska. (Anderson.)

 337. Eed-tailed Hawk. 



Buteo horealis (Gmel.) Vieill. i8i6. 



We have no records of this species being seen in the district of 

 v^Ungava (Labrador), but it breeds in Newfoundland, Nova Scotia, 

 Prince Edward Island, New Brunswick, Quebec and Ontario. Mr. 

 Spreadborough saw a few specimens on the Missinabi river and on 

 Moose river, near James bay. Preble saw it, evidently breeding, 

 at several places between Lake Winnipeg and Hudson bay, and 

 Dr. Bell took it at Fort Churchill, Hudson bay. This species is 

 abundant in the wooded portions of Manitoba, especially in the Rid- 

 ing mountains. Duck mountains, Porcupine hills and northward to 

 the Saskatchewan. Westward, Spreadborough found it nesting at 

 Indian Head, Sask., also near Peace River landing and Dunvegan, 

 Peace River district., and south along the foothills to Crow Nest 

 pass, but not being a prairie species it disappears with the wood. 

 I agree fully with Seton in his "Birds of Manitoba," when he says 

 on page 529 : ' 'This species seems to be the complement of Swainson 

 hawk in Manitoba, adhering to the forest regions, while the latter 

 is found only in the more open places. The differences of habit 

 presented by these two species are slight but quite appreciable." 



This species is common in the Northwest Territories, which it 

 visits in summer. Specimens were shot in the Rocky mountains,
