" greenlets," because their color harmonizes with the 

 foliage in which they spend their time. The under parts 

 of the body are white, or nearly so, in most species, but 

 the throat and breast of the yellow-throated vireo are 

 bright yellow. The red-eyed vireo has over each eye a 

 white line bordered with black. It is a trifle larger 

 than the warbling vireo, and its back shows more green 

 color. In most parts of the United States two or three 

 other kinds of vireos may be seen either during the 

 migration season or throughout the summer. They eat 

 cankerworms, chinch bugs, and the eggs and larvae of 

 various other insects. 



Few birds are heard in the woods as often as the red- 

 eyed vireo, and few in town as often as the warbling vireo. 

 Yet neither is known by many persons. The warbling 

 vireos often nest in shade trees overhanging sidewalks. 

 Their nests, like those of other vireos, are suspended from 

 a forked branch.
