 Ga. 



tributed in our country. In plumage, they are very incon- 

 spicuous, there being neither any black head marking nor 

 any well-defined superciliary stripe, but the flanks are tinged 

 with yellow, contrasting with the otherwise soiled white 

 under parts. They can best be identified in life by their song 

 which is a lively warble of a few seconds' duration, sounding 

 considerably like the song of the Purple Finch — so near 

 like it as to confuse a great many bird students. Warbling 

 Vireos swing their compact little baskets higher up in taller 

 trees than are commonly used by the last species. The 

 PHILADELPHIA VIREO is one of the rarest of eastern 

 vireos. Its song is quite like that of the Red-eye, but its 

 plumage nearest resembles that of the Warbling, but it can 

 usually be identified in life since the under parts are a uniform 

 pale yellowish. 



YELLOW-THROATED VIREOS are a handsome species 

 easily identified by plumage and also by song. The song is 

 even more deliberate than that of the Red-eye and the pauses
