Range. Eastern United States, breeding in the 

 southern half. 



The upper parts of this handsome species are 

 bluish gray with a greenish patch in the middle 

 of the back; the throat and breast are yellow 

 with a patch of black and chestnut. They are 

 abundant birds in suitable localities, breeding in 

 swamps, especially those with old or dead trees 

 covered with hanging moss (usnea). The nests may be found 

 at any height from the ground, and are usually made by turn- 

 ing and gathering up the ends of the hanging moss to form a 

 pocket, which is lined with fine grass or hair. The four to six 

 eggs are white or creamy white, wreathed with specks of reddish 

 brown and chestnut. Size .64 x .44. 



648a. NORTHERN PARULA WARBLER. Compsothlypis americana usnece. 



Range. Northern half of eastern United States and southern Canada ; winters 

 from the Gulf States southward. 



The nesting habits of the northern form of the Blue-yellow-backed Warbler 

 are in all respects like those of the last, and like them, where moss grown 

 swamps are not to be found, they have been known to construct nests of moss 

 suspended from branches of trees, or to nest in bunches of dead leaves. Data. 

 Oxford, Mass., June 7, 1895. Nest in a dead pine swamp; made in end of hanging 

 moss about 6 feet from the ground. Large colony breeding.
