The Warbling Vireo, hidden in leafy tree tops, is more often heard 

 than seen. Its song is very different from that of the Red-eyed, being 

 continuous and not composed of disconnected phrases. 



628. Yellow-throated Vireo. FR. LB VIREO A FRONT JAUNE. Lanivireo flavifrons. 

 L, 5-95. Head, cheeks, and back greenish; rump and tail slaty; breast and throat bright 

 yellow; below white; wings with two distinct white bars. 



Distinctions. The bright yellow breast and throat of this species are distinctive. The 

 Solitary and the White-eyed are the only other Vireos with wing-bars. In the former the 

 bars are white as in the breast, in the latter the bars are yellowish. In coloration the Yellow- 

 throated Vireo is very similar to the Pine Warbler, but there is much less white on the under- 

 parts of the latter species, the yellow suffusing and covering most of it instead of stopping 

 almost sharply at the breast line. 



Field Marks. The bright yellow throat and breast are distinctly recognizable and 

 prevent confusion with any other native Vireo. The voice, similar to that of the Red- 

 eyed but with the phrases following each other less rapidly 2 to 3 seconds apart instead of 

 about one per second, will distinguish it from others of its family or from the Warblers. 



Nesting. Suspended from a forked branch 10 to 80 feet above the ground, in pensile 

 nest of strips of bark, plant fibres, etc., lined with fine grasses and covered externally with 

 lichens, spider-webs, etc. 



Distribution. Eastern North America. Common in eastern Canada only in the 

 southern parts of the lower Great Lakes region. 



A woodland and orchard bird. Besides its characteristic song it makes 

 many queer noises and has an extensive vocabulary. 



629. Solitary Vireo. BLOT-HEADED VIREO. PR. up VIREO A TETE BLEUE. 

 Lanivireo solitarius. L, 5-61. Back greenish shading into bluish ash on head and adjacent 

 parts of cheeks; white loral spot and white ring about eye; all underparts white with 

 suffusion of yellow on flanks; wings with two whitish bars. 



Distinctions. The ashy blue head with conspicuous white lores and eye-ring are 

 distinctive. 



Field Marks. The bluish head with white eye-ring and lores and pure white throat 

 make conspicuous field marks. 



Nesting. Suspended from between the forks of a small branch 5 to 10 feet above the 

 ground, in pensile nest of wood fibres, bark strips, and pine-needles, plant-down, etc. 



Distribution. As a species the Solitary Vireo extends over all the United States and 

 Canada north to the extreme limits of settlement. The Blue-headed, the eastern repre- 

 sentative of the species, ranges west to central Alberta. 



SUBSPECIES. The Solitary Vireo is divided into several subspecies, only one of 

 which, the Blue-headed Vireo L. s. solitarius, to which the type belongs, occurs in eastern 

 Canada. 



A pretty little Vireo and a common inhabitant of woodland and 

 orchard during migrations. The song is similar to that of the Red-eyed, 

 but an attentive ear can easily distinguish between them. 



631. White-eyed Vireo. PR. LE VIREO ATJX YETTX BLANCS. Vireo griseus. L, 5-27. 

 A small Vireo like the Warbling but of much richer green colour on back and with yellow 

 loral mark and eye-ring; iris white. Throat and underparts almost pure white; strongly 

 yellow on flanks; wings have two yellowish bars. 



Distinctions. White iris, yellow eye-ring and loral mark, strong yellow on flanks, and 

 white breast and abdomen. 



Field Marks. This species is too rare in Canada and too similar to other species to 

 be recorded on eyesight observation alone. 



Nesting. Nest usually similar to that of the Red-eyed. 



Distribution. All forms of the species are southern. The eastern White-eyed occurs 

 in the eastern United States north to New York and Massachusetts and is only accidental 

 in Canada.
