BIRDS OF ONTARIO. 



GENUS CHONDESTES. 



(*) (55 2 ) Lark Sparrow. 



(Chonaestes grammacus.) 



A regular, but not a common, summer resident of some localities in 

 southern Ontario. I find a few pairs near Toronto every season. 

 Breeds where it occurs.

(554) White=crowned Sparrow, 



(Zonotrichia leucophrys.) 



A common migrant, arriving about the tenth of May and soon pass- 

 ing northward, returning towards the end of September and departing 

 southward late in October. 



Breeds in the far north. 



White-throated Sparrow. 



(558) White=throated Sparrow. (Peabody.) 

 (Zonotrichia albicollis.) 



Very abundant during the migrations and a regular, though not a 

 common, summer resident in southern Ontario, where a few pairs always 

 remain to breed. 



Arrives about the end of April, departs southward early in October.
