BIRDS OF NEW YORK 37 r 



Haunts and habits. In southern and western New York, this is one 

 of our common birds of the orchard and shade trees. Almost every village, 

 city and parkland boasts pairs of the Warbling vireo. Every few blocks 

 it can be located by the song of the male as one journeys about the streets. 

 As to the birds themselves, they are very rarely seen, even by the inhab- 

 itants in front of whose houses they build their nests. The song of this 

 species is a rolling warble longer than the strain of the Red-eyed vireo 

 and not so frequently repeated. It reminds one somewhat of the song 

 of the Purple finch but is not so full and is delivered with less intensity 

 and variety. 



The nest of the Warbling vireo is suspended from the fork of an apple 

 tree, maple or some other shade tree, at a height of from 15 to 40 feet from 

 the ground. In structure it resembles slightly the nest of the Red-eye, 

 but is smaller and more compactly put together and not ornamented on 

 the exterior so uniformly with spiders' nests and other downy bunches. 

 The eggs, deposited from May 23 to June 15, are usually 4 in niunber, 

 white, less sparingly spotted than those of the Red-eye with specks of 

 black, limber and reddish brown. They average .76 by .55 inches. 



The spring arrival dates from April 30 to May 8, rarely as early as 

 April 26, and it disappears in the autimm from September 10 to 22.
