at first and the iris a dirty white, and it was not until they were a 

 month old that their eyes attained the bright yellow appearance. 

 (Spreadborough.) 



375b- Arctic Horned Owl. 



Bubo virginianus arcticus (Swains.) Cass. 1854. 



The following citations are all probably referable to subarcticus 

 but without the specimens this cannot be determined. 



One shot near Duck mountain, Manitoba, in the fall of 1883; 

 another individual was taken by Macoun in October, 1880, in the 

 Touchwood hills, Sask. {E. T. Seton.) This very beautiful owl 

 appears to be rare, one specimen having been seen flying at mid-day 

 in the immediate vicinity of Carlton House and was brought down 

 by an arrow by an Indian boy. (Richardson.) One seen at Peace 

 River Landing, Atha., in 1903. (Spreadborough.) This owl or the 

 other variety was repeatedly observed in the country between Fort 

 Good Hope and the Anderson river. (Macfarlane.) This pale- 

 coloured form is sometimes seen in northern Alberta where it breeds. 

 (W. Raine.) Bent and Bishop collected four specimens in western 

 Saskatchewan which were all more or less intermediate being fully 

 as light coloured as the average arctic but having spotted rather 

 than pure white feet. 



375c. Dusky Horned Owl. 



» 



Bubo virginianus saturatus Ridgw. 1877. 



Not rare at Fort Chimo, Ungava. Resident. Downy young 

 obtained June 20th, 1884. (Packard.) A rare winter visitant at 

 Montreal. I purchased a fine specimen of this owl, February 8th, 

 1892, in the Bonsecours market, which was shot at Boucherville 

 four days previously. (Wintle.) Among the horned owls taken at 

 Toronto in winter are a few very dark birds usually of large size 

 and apparently referable to the form heterocnemis of Oberholser. 

 (/. H. Fleming.) 



This species is an extremely dark-coloured form of the horned 



owl, found along the damp, heavily wooded south coast of the 



Alaskan territory, and extending its range southward to Washington. 



(Nelson.) An abundant resident west of the Coast range. (Fannin.)
