306 SYSTEMATIC SYNOPSIS. — PASSERES — OSCINES. 
and curious song; an expert fly-catcher, constantly darting into the air in pursuit of winged 
insects, like the Redstart and the species of Mytodioctes. Breeds throughout its U. 8. range; 
winters in Florida and the West Indies. Nest on a bush or sapling near the ground; a'small, 
neat, compact structure; eggs 3-6, not peculiar. : 
D. gra/ciz. (To Miss Grace D. Coues, the author's sister.) Gracr’s WARBLER. Entire 
upper parts ashy-gray, with a slaty-blue tinge; the middle of the back streaked with black, 
the upper tail-coverts less conspicuously so marked; the crown with crowded black arrow- 
heads, especially anteriorly and laterally, the tendency of these markings being to form a line 
along the side of the crown, meeting its fellow on the forehead. A broad superciliary 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 crescentic 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-markivgs as in summer, and the yellow 
parts quite as bright. 9: Quite similar to the male, and in fact scarcely 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 obselete. 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 ochrey tinge, and the lateral streaks are 
not so heavy in color nor so well defined. Southern Rocky Mt. Region of the U.S. and south- 
ward; a beautiful species, related to dominica and adelaide ; it is abundant in the pine woods 
of Arizona and New Mexico. Nesting still unknown. 
D. domin‘ica. (Lat. dominicus, of St. Domingo.) YELLow-THROATED WARBLER. Much 
like the last species, with which its changes of plumage correspond; back without black 
streaks ; uo 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 crown 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. Bill 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. 8. range at large ; 
winters in Florida and extralimital. 
D. d. albilo’ra. (Lat. albus, white ; lorwm, the lore.) WHITE-BROWED WARBLER. Pre- 
cisely like the last; but superciliary stripe entirely white, and yellow of chin cut off from Dill 
by white. This slight variety (considering how variable dominica 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. 
D. kirt/landi. (To Dr. Jared P. Kirtland, of Ohio.) KirTnanp’s WarBLer. gf: 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 
and the sides with short streaks of black; greater and middle wing-coverts, quills, and tail-
