YOl i907" IV ] Fleming, Birds of Toronto, Canada. 75 



The resident form in Southern Ontario is remarkably constant in color; 

 the plumage is dark in tone, with comparatively little tawny or ochraceous; 

 rufous birds are rare. Among those that visit us in winter there is an 

 endless variation of color; one specimen is ashy gray. 



146. Bubo virginianus subarcticus. Arctic Horned Owl. — Of 

 recent record here; there are none in old collections. I have examined 

 four well marked birds since 1893; of these two were typical, the others 

 rather more heavily marked, but none approached occidentalis, there 

 being comparatively little ochraceous underlying the white. 



147. Bubo virginianus saturatus. Dusky Horned Owl. — Among 

 the horned owls taken here in winter are a few very dark birds, usually 

 of large size and apparently referable to the form heterocnemis of Oberholser. 



148. Nyctea nyctea. Snowy Owl. — Regular migrant, October to 

 January, sometimes abundant. The years of unusual abundance, as far 

 as known, are 1833, '37, '39, '53, and '62; 1 in more recent times the years 

 are 1884, '88, '89, '96, and 1901. The flight of 1901-02 extended from 

 December to April; a few specimens were taken in May, and one on June 

 7. 2 



149. Surnia ulula caparoch. American Hawk Owl. — Rare winter 

 migrant of irregular occurrence, October 22 to January 10; I have the 

 records of only three specimens since 1889, but there are several previous 

 to this date. 



150. Coccyzus americanus. Yellow-billed Cuckoo. — Summer 

 resident, not very common, May 28 to August 23; latest date September 

 21, 1906 (J. H. Ames); breeds (July 1, 1891). This cuckoo was regarded 

 as very rare here till 1889. 



151. Coccyzus erythrophthalmus. Black-billed Cuckoo. — Regu- 

 lar summer resident, not uncommon May 15 to August 30; breeds (June 

 2 and August 12, 1889; July 6 and 20, 1895). Mr. Geo. E. Atkinson 

 records the finding of eggs of this cuckoo in nests of the Wood Pewee and 

 Yellow Warbler at Toronto 3 and Dr. C. K. Clarke records several instances 

 of the same thing at Elora, Ont. 4 



152. Ceryle alcyon. Belted Kingfisher. — Summer resident, com- 

 mon April 1 to October 10; earliest record March 6, 1894 (J. Hughes 

 Samuel) ; breeds. 



153. Dryobates villosus. Hairy Woodpecker. — Common migrant 

 and rather rare winter resident; my records are all between October 11 

 and April 4, and it does not appear to breed here. This form is the one 

 occurring in southern Ontario, at least south of Lake Nipissing, and I 

 have not found leucomelas. 



154. Dryobates pubescens medianus. Downy Woodpecker. — Resi- 

 dent; breeds; an abundant migrant.
