653. Mangrove Warbler. Dendroica bryanti 

 castaneiceps. 



Range. — Southern Lower Cali- — 



fornia and western Mexico and 

 Central America. 



This species is very similar to 

 the Yellow Warbler but the en- 

 tire head and neck of the male 

 are yellowish chestnut. Their 

 nesting habits or eggs do not vary in any essen- 

 tial particular from those of the common Yellow- 

 birds of the United States. 



654t. Black-throated Blue Warbler. Den- 

 droica ccerulescens ccerulescens. 



Range. — Eastern North America, breeding from 

 northern United States northward; winters in 

 the Gulf States and southward. 



These black-throated bluish-backed Warblers 

 are abundant in swampy woodland both during 

 migrations and at their breeding grounds; either 

 sex can readily be identified in any plumage, by 

 the presence of a small white spot at the base of 

 the primaries. They nest in underbrush or low 

 bushes only a few inches above the ground, mak- 

 ing the nests of bark strips, moss rootlets, etc., 

 lined with fine grasses or hair; 

 the eggs are pale buffy white 

 more or less dotted with pale 

 brownish; size .65 x .50. Data. 

 —Warren, Pa., June 9, 1891. 3 

 eggs. Nest one foot from the 

 Buffy white ground in brush; made of fine 

 pieces of rotten wood, laurel bark and lined with 

 fine grasses. 



654a. Cairns Warbler. Dendroica ccerulescens cairnsi. 



Range.— Mountain ranges of North Carolina to Georgia. 



A darker form whose habits and eggs are identical with those of the last.
