Containing a concise account of every species of living and fossil bird at present known from the continent north of the Mexican and United States boundary, inclusive of Greenland and lower California, with which are incorporated General ornithology: an outline of the structure and classification of birds; and Field ornithology, a manual of collecting, preparing, and preserving birds. Birds; Birds; 1887. SYLVICOLIB^ — SYLVIGOLIN^^ : TRUE WAliBLEliS. -301 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, 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.
