 of the United States except in the Rockies south to Arizona and 

 New Mexico; winters in the Gulf States and southward. 



This plainly clad, greenish colored species has a concealed 

 patch of orange brown on the crown. They have been found 

 [White.] breeding about Hudson Bay and in the Mackenzie River district, 

 placing their nests in hollows on the ground, usually on the side of banks or

 are white, speckled with reddish brown. Size .64 x .45. 



646a. Lutescent Warbler. H. c. lutescens. 



Range. Pacific coast, breeding from California to Alaska; winters in Mexico. 



Similar to the last but more yellowish below. They make their nests of 

 leaves, rootlets, moss, etc., lined with hair, and placed on the ground, concealed 

 by tufts of grass or by bushes. The eggs are like those of the last. Data. 

 Danville, Cal. April 21, 1898. Nest on the ground on a side hill; among weeds 

 in the shade of a large oak. Collector, Claude Cummings. 



646b. Dusky Warbler. H. c. sordida.

 Said to be duller colored and darker than the others, 

 distinguished. 



647. Tennessee Warbler. Helminthophila peregrina. 



^ ~ > Range. Eastern North America, breeding from the northern 



tier of states, northward; winters to northern South America. 



This species has greenish upper parts, white lower parts and 

 superciliary line, and gray crown and nape. They nest either on 

 the ground or at low elevations in bushes, making the structure 

 [White.] of grasses and fibres, lined with hair; they are found on wild, 

 tangled hillsides and mountain ranges. The eggs are pure white, sparingly 

 specked with reddish brown. Size .62 x .45. 



648. Parula Warbler. Blue-yellow-backed Warbler. Compsothlypis americana. 

 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 V 

 birds in suitable localities, breeding in swamps, especially those [White.] 

 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 turning 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. C. a. usnese. 



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.
