found an owl lighter in colour than pure virginianus and yet darker 

 than arcticus, this form is generally accepted as the western 

 horned owl, and as long as the division of the horned owls is 

 maintained we must admit this form as a Toronto bird. (/. H.

This foi-m is a common resident in'Manitoba wherever there is 

 timber; this form of Bubo is lighter in colour than the true Bubo 

 virginianus subarcticus. It is probably just intermediate between 

 that form and var. arcticus. Evidently a common permanent 

 resident in Manitoba as all. observers agree in this. (Thompson- 

 Seton.) Fine specimens of this fdrm were taken at Indian Head, 

 Assa., in May, 1892 ; at Medicine Hat and Crane Lake, Assa., 

 May, 1894 ; and in the Cypress Hills in June of the same year ; 

 a few were seen on Old Wives' Creek, Assa., and at the West 

 Butte, Lat. 49°, Assa., 1895 i occasionally seen at Banff, Rocky 

 Mountains, in the summer of 1891 ; observed near Cascade and on 

 Sophie Mountain, B.C., at the International Boundary in July, 

 1902 ; one taken at Agassiz, B.C., May, 1889. {Spreadborough.) 

 This bird is found in all parts of the Northwest Territories where 

 the timber is large and was taken by Mr. Drummond in the Rocky 

 Mountains. {Richardson.) North to Arctic Circle and beyond, 

 on the Mackenzie River. {Ross.) This bird is found throughout 

 the entire wooded part of northern Alaska, extending its range 

 in autumn to the open treeless shore along Behring Sea and 

 portions of the Arctic coast. {Nelson.) This bird is only an occa-

 taken by the snowy owl. {Tutner.) Abundant east and west of

Breeding Notes.— September 18th, 1884, Portage la Prairie : 

 Mr. C. W. Nash gives me a very interesting note on a pair of 

 horned owls that had nested in the woods here, and from the 

 indications observed there seems little doubt that they subsist 

 chiefly on fish, which were abundant in a small creek running from 

 a lake through these woods to the Assiniboine River. On exam-
