348 BIRDS OF ONTARIO. 



Trusting that the exodus was only local and temporary, we watc-hed 

 for the return of the birds with interest. 



The species evidently overlooked its Hamilton connection in 18S6, 

 but it has since then been as common as formerly, watching silently 

 near the roadside for its favorite fare of beetles, mice, or small birds. 

 It is very common in the west, going as far north as Manitoba. In 

 the east it Seems more rare, Mr. White not having yet observed 

 it at Ottawa, though he has looked for it during several seasons.

A ver}' common suinaler resident is the Red-eyed Vireo, and his 

 loud, clear notes are heard in the outskirts of the woods at all hours 

 of the day. Even during the sultry month of July, when most other 

 songsters sing only in the morning or evening, the Red-eye keeps on 

 all day with tireless energy. In Ontario it is the most numerous 

 species of the family, arriving early in May and leaving in September.
