RED-EYED VIREO. 
VIREO OLIVACEUS. 
‘HIS lively, tireless singer, running rapidly after 
insects in the tops of the forest trees, singing as 
he goes, is heard more hours in a day and more days in 
the season than any other bird. There is no difficulty 
in distinguishing him, the bird so easy to hear and so 
hard to see. The clear, high tones of his rich voice are 
a constant repetition of a few triplets, but so ingeniously 
arranged as not to become wearisome : — 
This illustration, containing the substance of the red- 
eyed vireo’s song, has much in common with the music 
of other birds. The nest is after the fashion of the 
oriole’s, hanging, as I have found it, beneath the fork 
of small beech limbs, five or six feet from the ground. 
It is a nice little pocket, as the cow-bird well knows.
