Bange.—-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 Tillandst'a “moss,” lined with vege- table down, thirty to forty feet from the ground, in pines or live-oaks, some— times in a bunch of Tillandst'a “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 [act that they resort to the upper branches, makes it some- times difiicult to locate the singer.

663a. D. d. albllora 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., 260; 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).
