oKvaceous, and the hlack interrupted and restricted. 9 entirely different : Dull olive-greenish, 

 with faint bluish shade, below [)ale soiled yellowish ; but recognizable by the ivhite spot at base 

 of primaries, which, though it may be reduced to a mere speck, is nearly always evident, at 

 least on pushing aside the primary coverts ; no other wing-markings ; tail-blotches small or 

 obscure; feet rather pale. Size of virens. Kastern U. S., abundant, in woodland, its range 

 closely coincident with that of virens. It is, however, rather a bird of brake and biu-n 

 than of higli W(.iods, at least in summer ; and nests in bushes, clo.se to the ground. Eggs not 

 peculiar. A beautiful bird, the $ with black, white and blue in masses, thus resembling no 

 otlier, and the olive-colored 9 as different as possiUo from her mate. 



118. D. coeru'lea. (Lat. caerukiis, cerulean, sky-blue.) Cerulean Wakblee. Azure War- 

 bler. J', adult : Entire upper parts sky-blue, the middle of the back streaked with black ; the 

 crown usually richer and also with dark markings. Below, pure white, streaked across the 

 breast and along the sides with dusky-blue — the breast-streaks inclining to form a short bar, 

 sometimes interrupted in the middle. Auriculars dusky; edges of eyelids and superciliary line 

 white. Wings blackish, much edged externally with the color of the back, the inner webs of 

 all the quills, the outer webs of the inner secondaries, and two br(jad bars across the tips of the 

 greater and median coverts, white. TaU black, with much exteiior edging of the color of the 

 back, all the feathers, except the middle pair, with small, white, subterminal spots tm the inner 

 webs. Length 4.00-4.50 ; wing 3.66 ; tail 2.00 or less. ?, adult: Quite difi'erent. Upper 

 parts dull greenish, with more or less grayish-blue shade, the greenish brightest and purest on 

 tin: crown. Eyelids, line over eye, and entire under parts, whitish, more or less strongly over- 

 cast with dull greenish-yellow. Wings and tail dusky, the exterior edgings of the color of the 

 back ; the bars, spots, and interior edgings white, as in the ^ . The female is curiously sim- 

 ilar to the same sex of D. ccendescens, but in the latter the tail-spots are different ; there are no 

 white wing-bars, but instead there is a small whitish spot at the base of the outer primaries. 

 The autumnal plumage of the adults is said to differ in no wise from that of the spring. Young 

 males are much like the adult females, but less uniformly greenish-blue above and purer white 

 below, with evident blackish stripes on the interscapulars and sides of the head. The young 

 female resembles the adult of that sex, but is still greener above, with little or no blue, and quite 

 buffy-yellowish below. When in full dress this is a perfect little beauty, there being somethins: 

 peculiarly tasteful and artistic in the simple contrast of the snowy-white with the dehcate azure- 

 blue, without any "warm" color. Eastern U. S., rarely north to New England; west some- 

 times to the Kocky Mts. in the latitude of Colorado. One of the rarer species. Nest small 

 and neat, in fork of a bough 20-.50 feet from the ground ; eggs 4, creamy-white, heavily 

 blotched with reddish-brown, 0.60 X 0.47. 



119. D. corona'ta, (Lat. coronata, crowned ; corona, a crown. Fig. 165.) Yelldw-rumpbd 

 Warbler. Yellow-crowned Warbler. Myrtle Bird. <J, in spring: Slaty-blue, 

 streaked with black; below, white, breast and sides mostly 

 black, belly, and especially throat, pure white, immaculate; 

 rump, central crormi-patch, and sides of breast, sharpily yellow, 

 there being thus four definite yellow places ; sides of liead 

 black ; eyeUds and superciliary line white ; ordinary white 

 wing-bars and tail-blotches ; bill and feet black. $ in winter, 

 and 9 in summer, similar, but slate-color less pure, or quite 

 brownish; young birds are quite brown above, with a few 

 obscure streaks in the whitish of the under parts. It is im- 

 possible to specify the endless intermediate styles; but I never Pig. 165.— Tellow-rumpeii War-
