230 GEOLOGICAL SURVEY OF CANADA, 



Vancouver Island, Aug. 2nd, 1893. {Spreadborough) 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.) 



CXXIV. BUTEO CuviER. 1779- 1800. 

 ssT. Red-tailed Hawk. 



Buteo borealis (Gmel.) Vieill, 1816. 



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

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

 Prince Edward Island, New Brunswick, Quebec and Ontario. 

 Mr. Spreadborough saw three specimens on Moose River, near 

 James Bay, June 6th, 1896, and Dr. Bell took it at Fort Churchill, 

 Hudson Bay. This species is abundant in the wooded portions 

 of Manitoba, especially in the Ridil»g Mountains, Duck Moun- 

 tains, Porcupine Hills and northward to the Saskatchewan. 

 Westward, Spreadborough found it nesting at Indian Head in 

 Assiniboia, and at Edmonton, Alta., and along the foothills to 

 Crow's Nest Pass, but not being a prairie species it disappears with 

 the wood. I agree fully with Thompson-Seton in his " Birds of 

 Manitoba," when he says on page 529 : " This species seems to be 

 the complement of Swainson's 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." As no specimens of Krider's 

 Hawk have been recorded from southern Manitoba all the east- 

 ern prairie region and the northern forest up to Lat. 60" are 

 included in the range of the Red-tail. 



This species is common in the Northwest Territories which it 

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

 on the plains of the Saskatchewan, and at York Factory, Hudson 

 Bay between Lat. 53^^ and 57°. {Richardson^ This species is far 

 outnumbered at London, Ont., by the Red-shouldered Hawk. 

 More common in the more remote districts. {W. E. Saunders.) 



Breeding Notes. — This is a rare bird along the St. Lawrence. 

 In eleven years I am only certain of having seen one specimen. 

 In the counties of Lanark and Renfrew it is common and I used 

 to see it every year. Within a few miles of the village of Ren-
