WOOD WARBLERS. 361 



663. Dendroica dominica (Linn.}. YELLOW-THROATED WARBLER. 

 Ad. A yellow line in front of the eye and a white line over it ; upper parts 

 gray, forehead blackish ; wings and tail edged with grayish, two white wing- 

 bars ; outer tail-feathers with white patches near their tips ; cheeks and sides 

 of the throat black ; a white patch on the side of the neck ; throat and breast 

 yellow, belly white, sides streaked with black. L., 5-25; W., 2-60 ; T., 2-01 ; 

 B., -49. 



Range. Southern United States ; breeds as far north as Virginia ; winters 

 from Florida southward; accidental in New York and Massachusetts. 



Washington, rare S. R., rather common in late July ; may breed. 



Nest, of twigs, strips of bark, and Tillandsia, " moss," lined with vege- 

 table down, thirty to forty feet from the ground, in pines or live-oaks, some- 

 times in a bunch of Tillandsia "moss." Eggs, four to five, white or grayish 

 white, with numerous distinct and obscure cinnamon- or olive-brown mark- 

 ings, sometimes evenly distributed, sometimes in a wreath at the larger end, 

 74 x -52. 



Some birds are so characteristic of certain places that wherever 

 heard or seen they recall their accustomed haunts. I have only to re- 

 member the song of the Yellow-throated Warbler to give form to a 

 mental picture of some tree-bordered stream or bayou in the south. The 

 song bears some resemblance to that of the Indigo Bunting, but has a 

 wilder, more ringing quality. It is to some extent ventriloquial, and 

 this in connection with the rather deliberate movements of the birds, 

 and the fact that they resort to the upper branches, makes it some- 

 times difficult to locate the singer. 



663a. D. d. albilora Ridgw. SYCAMORE WARBLER.- -Similar to the 

 preceding, but with a smaller bill and the line in front of the eye white in- 

 stead of yellow. W., 2-60 ; T., 2-00 ; B., -45. 



Range. Breeds in the Mississippi Valley north to Kansas, southern In- 

 diana, and southern Illinois; east to western South Carolina; migrates south- 

 ward, chiefly along the west Gulf coast, to Mexico and Central America. 



" The Sycamore Warbler is a common summer resident in the bot- 

 tom-lands [of Illinois], where, according to the writer's experience, it 

 lives chiefly in the large sycamore trees along or near the water courses. 

 On this account it is a difficult bird to obtain during the breeding 

 season, the male usually keeping in the topmost branches of the tallest 

 trees, out of gunshot and often, practically, out of sight, although its 

 presence is betrayed by its loud, very unwarblerlike song " (Ridgway). 



667. Dendroica virens (Gmel.}. BLACK-THROATED GREEN WAR- 

 BLER. Ad. $ . Upper parts bright olive-green, back sometimes spotted with 

 black ; line over the eye and cheeks bright yellow, ear-coverts dusky ; two 

 white wing-bars; inner vanes of outer tail-feathers entirely white, outer web 

 white at the base; throat and breast black; belly white, sometimes tinged 

 with yellow ; sides streaked with black. Ad. 9 .Similar, but the black of
