BLUE-HEADED VIREO. 



629. Vireo solitariits. 5|4 inches. 



Crown and sides of head bluish slate; lores, eye-ring 

 and underparts white; back and flanks greenish yel- 

 low; two whitish wing bars. 



This species, to my eye, is the prettiest of the 

 Vireos, all the colors being in just the right proportion 

 and blending and harmonizing perfectly. They are 

 solitary, in that they are usually found in deep woods, 

 glens or ravines, and seldom is more than one pair 

 found in a single woods. 



Song. Similar to that of the Yellow-throated Vireo 

 but longer and more varied. 



Nest. A handsome, finely woven basket, with the 

 outside covered with spider webs and often with 

 lichens; eggs pale creamy white with chestnut specks. 



Range. Eastern N. A., breeding from the Gulf to 

 New Brunswick and Manitoba; winters south of the 

 United States. 



Sub-species. 629c. Mountain Solitary Vireo (alti- 

 cola), head darker and back less greenish; Alleghenios 

 from North Carolina to Georgia.
