BLUE-HEADED VIREO. 
629. Lanivireo solitarius. 5%4 inches. 
Crown and sides of head bluish slate; lores, eye-ring 
and underparts white; back and flanks greenish yellow; 
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.—Fastern 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; Alleghanies 
from North Carolina to Georgia.
