70 CHECK LIST OF THE 



(626) Philadelphia Vireo. 



(Vireo philadelphicus.) 



Tolerably common summer resident ; breeds throughout its range in 

 the Province. 



Arrives about the middle of May, departs at the end of September. 



(627) Warbling Vireo. 



(Vireo gilvus.) 



Common summer resident ; breeds throughout its range in the Pro- 

 vince. 



Arrives about the middle of May; departs in September. 



This species seems to prefer shrubberies and shade trees in city 

 streets to the seclusion of the woods. 



(628) Yellow=throated Vireo. 



(Vireo flavifrons.) 



An uncommon summer visitor which probably breeds with us, though 

 I have no actual record of the discovery of its nest here. 



Arrives about the beginning of May, departs early in September. 



(629) Blue-headed Vireo. (Solitary Vireo.) 



(Vireo solitarius.) 



A regular migrant in spring and autumn. Probably breeds in the 

 interior. 



Arrives early in May, departs at the end of September. 



(*) (631) White-eyed Vireo. 



(Vireo noveboracensis.) 



Mr. W. L. Kells has recorded the capture of one specimen near 

 Listowel, in the middle of October, 1890, and Mr. Hobson has taken an- 

 other near Woodstock. I have heard of no others. 



FAMILY MNIOTILTID^E. (WOOD WARBLERS.) 



Bill usually rather slender, notched or not ; the commissure not angu- 

 lated at base as in Fringillidae, nor toothed in the middle ; the end not 

 notched and abruptly hooked, as in Vireonidae ; the gape not broad 

 and reaching to the eyes, as in Hirundinidae. The Warblers are all small 

 birds, usually of brilliant colouration, but the sexes are unlike and the 

 variations due to age and season are great, so that the identification of 

 immature birds is sometimes troublesome. 



All are insectivorous and of great value to the horticulturist, as they 

 glean their insect food chiefly from the foliage and twigs of trees.
