663* Dendroica dominica (Linn.). YELLOW-THROATED WARBLER.

Washington, rare S. K., 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-

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. Th e 

 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 somo- 

 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 difficiilt 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- 

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

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