CATALOGUE OF CANAOIAN BIRDS. 2/3 



at Cape Darby on the Alaskan shore of Bering strait. (Nelson.) A 

 single specimen of this species was killed at St. Michael, 15th May, 

 1877. It is not a common bird in this vicinity, and oftener seen in 

 spring than at other seasons. (Turner.) 



354. Gray Gyrfalcon, 



Falco rusticolus Linn. 1758. 



The darker form of great northern falcon, by some held to be 

 distinct both from F. islandus and F. gyr falco. The northern limits 

 of its breeding range have not yet been determined. A young male 

 falcon killed 24th September, 1872, on the Fiskenses, referred by 

 Dr. Finsch to F gyrfalco probably belonged to this form. (Arct. 

 Man.) Common in north Greenland. (Winge.) Common resident 

 in Greenland and breeding at Ivigtut. (Hagerup.) Winter speci- 

 mens only obtained at Fort Chimo. Not known to breed in the 

 Ungava district. (Packard.) Probably occurs in Newfoundland. 

 (Reeks.) 



Casual. One specimen of this species was shot by Mr. E. White 

 on the banks of the Rideau, below Cummings Bridge, Ottawa, on 

 3rd December, 1890; another was shot by G. R. White some years 

 before. (Ottawa Naturalist, Vol. V.) Since the year 1885, I have 

 received over thirty sets of the eggs of this fine bird from Iceland. 

 It lays from three to four handsome eggs, making a slight nest on 

 ledges of the sea cliff. (W. Raine.) Very rare at Aweme, Man. 

 (Criddle.) A female was caught in a trap at St. Michael, Alaska, 

 Sept. 2ist, 1899. (Bishop.) 



354a. Gyrfalcon. 



Falco rusticolus gyrfalco (Linn.) Stejn. 1885. 



There is no doubt but that this form was included in F. islandus 

 by Sir John Richardson as he found the birds nesting not far from 

 where Macfarlane found this species 40 years later. 



Taken in several places on EUesmere island. (E. Bay.) Seen 

 from 6th to 20th September, 1884, flying south at Wales sound, 

 Hudson strait. (Payne.) Taken at Fort Churchill, west side of 

 Hudson bay. (Clarke.) York Factory, Hudson bay. (Dr. R. Bell.)
