^°1908^^] General Notes. 487 



Migration of Horned Owls. The winter of 1907-'08 was marked in 

 southern Ontario by the presence of great numbers of Horned Owls; I 

 examined twenty-four between October 31 and February 26, and as far 

 as I was able to distinguish between them, the resident form of Bubo 

 virginianus was not present, and did not appear till the second week of 

 April, some time after the migration had ceased. The first November 

 birds were light Arctic Horned Owls (Bubo virginianus arcticus), followed 

 by others not so white, and several dark Labrador Horned Owls (Bubo 

 virginianus heterocnemis) . All winter the dark birds were the rarer, and 

 the majority of the owls examined were not referable to either of the three 

 forms, but were closer to arcticus than to virginianus, most of them hav- 

 . ing decided black and white markings and white feet. A very light male 

 was taken at Toronto November 1, 1907, and a very dark one November 26. 



Grinnell's Water-Thrush. I have in my collection three skins of 

 Grinnell's Water-Thrush {Seiurus noveboracensis noiabilis) taken at Toronto 

 in May, 1897, a male and female taken on the 4th by Mr. J. Hughes Samuel 

 and a male taken on the 7th by myself, all three from the vicinity of Ash- 

 bridge's Bay. While Ontario water-thrushes are probably intermediate 

 between the eastern and western forms, the typical western bird has not 

 been recorded before from Ontario. 



Philadelphia Vireo. A skin of the Philadelphia Vireo {Vireo phila- 

 delphicus) in my collection is of interest from the fact that the wings have 

 each a bastard primary of about half the length usual in the Warbling 

 Vireo, and while the case is not unique, it is rare enough to record. The 

 bird was taken by Mr. J. Hughes Samuel at Toronto, September 2, 1899. —
