best known species of birds in the east. They are sometimes 

 called "Preacher Birds" because of the deliberate delivery 

 and peculiar phrasing of their song, excellently written by 

 Wilson Flagg as, "You see it — you know it — do you hear 

 me? — do you believe it?" I know of no other bird that is 

 so persistent in its song. During spring and summer these 

 short phrases are uttered nearly all day long until they some- 

 times become very monotonous, particularly so when you 

 are trying to identify some other species by its song. 



The Red-eye is usually identified by its song; its plumage 

 is diagnostic however for the gray crown is narrowly bordered 

 by black, above a conspicuous superciliary stripe. The eye 

 is far from being red, but is of a reddish-brown shade, rather 

 brighter than that of other vireos. 



Their nests are skilfully woven baskets of strips of bark 

 and flat fibres, lined with vine tendrils, suspended by the 

 rim from forks of bushes or trees, usually not high up. 



WARBLING VIREOS are very common and widely dis-
