306 SYSTEMATIC SYNOPSIS. — PASSEBES— OSCINES. 



and curious song ; an expert fly-catcher, constantly darting into the air in pursuit of vidnged 

 insects, like the Eedstart and the species of Myiodioctes. Breeds throughout its U. S. range ; 

 winters in Florida and the West Indies. Nest on a hush or sapling near the ground ; a small, 

 neat, compact structure ; eggs 3-6, not peculiar. 



138. D. gra'ciae. (To Miss Grace D. Coues, the author's sister.) Grace's Waeblee. Entire 

 upper parts ashy-gray, with a slaty-hlue tinge ; the middle of the hack streaked with hlack, 

 the upper tail- coverts less conspicuously so marked; the crown with crowded hlack arrow- 

 heads, especially anteriorly and laterally, the tendency of these markings heing to form a line 

 along the side of the crown, meeting its fellow on the forehead. A broad supercUiary line of 

 yellow, confluent with its fellow on the extreme front, changing to white behind the eye. 

 Lores blackish ; sides of head otherwise like the back, enclosing a crescentie yellow spot below 

 the eye ; edges of eyelids yellow. Chin, throat, and fore breast bright yellow, bordered with 

 blackish streaks; the yellow of the throat separate from that under the eye or on the lores. 

 Under parts from the breast white, the sides shaded with the color of the back, and streaked 

 with black in continuation of the chain of shorter streaks along the side of the neck. Wings 

 dusky, with very narrow whitish edging, and crossed with two white bars along the ends of the 

 greater and median coverts. Tail like the wings; the lateral feather mostly white, excepting 

 the outer web ; the next two or three with white blotches, decreasing in size. Eyes, bill, and 

 feet black; soles dirty yellowish. Length 4.90-5.25; extent about 8.00 ; wing 2.60; tail 

 2.25; bill under 0.50. $, in autumn: Color of the upper parts obscured with a shade of 

 brownish-olive, the dorsal streaks obscure. The head-markings as in summer, and the yellow 

 parts quite as bright. ? : Quite similar to the male, and in fact scai-cely. distinguishable from 

 the male in autumn, though the yellow is not quite so strong. Young: The slate-gray of the 

 upper parts much shaded with brownish-olive, the black streaks wanting on the back, those on 

 the crown obsolete. Yellow much as in the adult but paler, and not bordered along the sides 

 of the neck with black streaks. The black lores are poorly defined. The wing-bars are gray- 

 ish or obsolete. The white of the under parts has an oohrey tinge, and the lateral streaks are 

 not so heavy in color nor so well defined. Southern Eocky Mt. Region of the U. S. and south- 

 ward ; a beautiful species, related to dommica and adelaidce ; it is abundant in the pine woods 

 of Arizona and New Mexico. Nesting still unknown. 



139. D. domin'ica. (Lat. dommicus, of St. Domingo.) Yellovt-throated .Warbler. Much 

 like the last species, with which its changes of plumage correspond; hack without black 

 streaks ; no yellow in the black under the eye. A white patch separating the black of the 

 cheeks from the bluish-ash of the neck; a long superciliary stripe, usually yellow from bill to 

 eye, thence white to the nape. Forehead and sides of crovm usually quite black, chin and 

 throat rich yellow, bordered on each side by black. Rest of under parts white, the sides boldly 

 streaked with black. BUI black, extremely compressed, almost a little decurved, very long 

 (at least 0.50). Length 5.00 or more; extent 8.00; wing 2.70; tail 2.25. A large hand- 

 some species, with its bright yellow throat. South Atlantic and Gulf States, common ; N. 

 sometimes to the Middle States, casually to New England. Breeds in its U. S. range at large ; 

 winters in Florida and extraUmital. 



130. D. d. albilo'ra. (Lat. alhus, white ; hrum, the lore.) White-brow^ed Warbler. Pre- 

 cisely like the last ; but superciliary stripe entirely white, and yellow of chin cut oft' from biU 

 by white. This slight variety (considering how variable dommica is in amount of yellow in 

 the superciliary line) is the common form of the Mississippi and Ohio valley, north regularly to 

 Ohio, Indiana, Illinois, W. to Kansas and Texas. 



131. D. kirtlandi. (To Dr. Jared P. Kirtland, of Ohio.) Kirtland's Warbler. $ : Upper 

 parts slaty-blue ; crown and back streaked with black ; lores and frontlet black ; eyelids 

 mostly white. Under parts clear yellow, whitening on crissum, the breast with small spots
