294 NORTH AMERICAN BIRDS EGGS. 



653. Mangrove Warbler. Dendroica bryanti castaneiceps. 



Range. Southern Lower California and western Mexico and 

 Central America. 



This species is very similar to the Yellow Warbler but the 

 entire head and neck of the male are yellowish chestnut. Their 

 nesting habits or eggs do not vary in any essential particular 

 [Greenish white.] from those of the common Yellowbirds of the United States. 



654. Black-throated Blue Warbler. Dendroica cserulescens. 



Range. Eastern North America breeding from northern United States north- 

 ward; 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, making the nests of bark [Buffy white ] 

 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 ground in 

 brush; made of fine pieces of rotten wood, laurel bark and lined with fine grasses. 

 Collector, R. B. Simpson. 



654a. Cairns Warbler. D. c. cairnsi. 

 Range. Mountain ranges of North Carolina to Georgia. 

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



655. Myrtle Warbler; Yellow-rumped Warbler. Dendroica coronata. 

 Range. Eastern North America, breeding from northern United States north- 

 ward. Winters in the southern half of eastern United States. 



f? r * This beautiful gray, white and black Warbler can readily be 



* identified by its yellow rump, side patches and crown patch. It 

 is one of our most common species during migrations when it is 

 found west to the Rockies and casually farther. They nest on 

 the lower branches of coniferous trees, making their homes of 

 [White.] rootlets, plant fibres and grasses; during June or the latter part 

 of May, three or four eggs are laid; they are white, spotted with several shades 

 of brown and lilac; size .70 x .50. Data. Lancaster, N. H., June 7, 1888. 

 Nest in a small spruce, about 6 feet up; made of fine twigs, lined with feathers. 

 Collector, F. B. Spaulding. 



656. Audubon Warbler. Dendroica auduboni. 



Range. Mountain ranges of western United States from British Columbia to 

 Mexico. 



This bird resembles the last in the location of the yellow patches .^^ . 

 but has a yellow instead of a white throat, and is otherwise dif- 

 ferently marked. They are as abundant in suitable localities as 

 are the Myrtle Warblers in the east, nesting on the outer branches 

 of coniferous trees at any height from the ground. The nests 

 are made of bark strips, rootlets, plant fibre, grasses and pine [Bluish white.] 

 needles, the three to five eggs are greenish or bluish white marked with brown 

 and lilac; size .68 x .52. The one figured is from a beautiful set of four in Mr. 

 C. W. Crandall's collection, and the ground color is a delicate shade of blue. 

 Data. Spanaway, Washington, April 23, 1902. Nest on the limb of a large fir 

 in a clump of three in prairie country. Collector, J. H. Bowles. 



656a. Black-fronted Warbler. D. a. nigrifrons.
