204 USEFUL BIRDS. 



Red-eyed Vireo. 



Vireo olivaceus. 

 Length. About six inches. 

 Adult. Upper parts grayish olive-green, changing to gray on the crown ; a dark 



stripe on either side of the crown ; a light stripe over the eye, arid dark 



streak from bill through eye ; under parts grayish-white, deepening to pale 



olive-yellow on the flanks ; iris ruby-red. 

 Nest. A pensile cup; usually hung by its upper edge from a fork, five to 



twenty-five feet from the ground. 



Eggs. White, spotted with dark brown at the larger end. 

 Season. May to September. 



The Red-eyed Vireo, although not so abundant as the 

 Robin, is one of the most common and widely distributed 

 summer birds. It breeds throughout the State. It is very 



devoted to its eggs and 

 young, and sits very closely

 bird will often allow a per- 

 son to walk by within arm's 

 length while she remains 

 quietly sitting. The par- 

 ent birds feed and protect 

 their young for a long time 

 after they leave the nest.

 she may be approached and taken in the hand. The Red- 

 eye is found wherever there are groups of deciduous trees, 

 or woodlands and thickets. Its movements as it slips about 

 among the branches are rather deliberate. It sings continu- 

 ally, but the song is intermittent, as though the bird were 

 singing incidentally as a pastime, like a boy whistling at his 

 work. The song is composed of phrases of a few syllables 

 each, and the manner of its delivery, with many rising and 

 some falling inflections and frequent pauses, led Wilson Flagg 

 to name the bird the " preacher." Many years ago I learned 

 that the preacher had other business than his preaching, and 

 that he practised as he preached ; for it was through watching
