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 
Riverwn: Mat. 60° +. Brooks.) 
CXXIV. BUTEO Cuvier. 1779-1800. 
337. 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 Riding 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 latteris 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. £. 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 afew miles of the village of Ren-
