Warbling Vireo 65 



outline description. It has been observed frequently in late 

 May and early June in Washington Park and along the city 

 streets where maple trees abound. It warbles a few phrases, 

 without beginning or end, and by its insouciant manner seems 

 to find the world a good place to live in, especially in places 

 where man has grown fine shade trees and cleared out the 

 undergrowth. 



The rattle of the ice-wagon on the city pavements has no 

 more terrors for Yellow-throat than for the Warbling Vireo, 

 and late in the year, after the leaves have fallen, its nest will 

 sometimes be revealed in the horizontal fork of some tall tree, 

 standing out against the wintry sky as a rebuke to the most 

 observing ornithologist. 



Warbling Vireo. — Vireo gilvus. 5.81 



Not Uncommon Summer Resident 



Field marks. — Upper parts grayish olive-green: lacks wing- 

 bars; under parts dull white; belly faintly washed with 

 yellow. 



The cheery, though somewhat monotonous warbling of this 

 bird is a familiar sound in almost all wooded places in this 

 section throughout the Summer. It is frequently heard in city 

 parks and about country homesteads. The singer keeps well 

 in the tops of trees and while heard constantly, is very rarely 

 seen. I have frequently stretched my neck and strained my 

 eyes in an effort to catch a glimpse of the musician, but 

 without result, although the bird was within twenty feet of me.
