Key to North American birds [microform] : 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. Birds; Ornithology; Oiseaux; Ornithologie. CAPBIMULGID^âCAPRIMULGIN^: TRUE GOATSUCKERS. 449 127. all our genera excepting Chordediles, tlie rictal bristles are an inch or more in length, in a firm regular series along the gapeâthey are relatively longer and stiffer than the whiskers of a eat. Our several genera are readily discriminated by good charactcTs of the nostrils, enormous rictal bristles, and comparatively short wings of the Night-jars proper, in comjjarison with tl>e slight bristles, forked tail and long pointed wings of Chordediles; they respectively represent two sections of the subfamily â Setirostres, bristled-billed (fig. 289), and Glabrirostres, smooth- billed (fig. 290). In both the feci are so extremely short that tlie birds cannot perch in the usual way, but sit lengthwise on a large branch, or crouch on the ground. Tliey lay two lengthened, white or thickly spotted eggs, on or near the ground, in stumps, etc. The sexes are , but nearly alike. The voice is peculiar, and has given several of the species their fanciful onomatopoetic names. Migratory. Obs. Since the orig. ed. of the Key was published, a fine genus and species, Nyetidromiis alhicolUs, has been added to our Fauna. " Xuttall's Whippoorwill" has been made the type of a new genus, Phal<B)wptili(s, on the ground of its naked feet, sJKjrt square tail, and other good characters. The (iomnion whippoorwill has been referred back to the old genus Caprimulgus. While it certainly dittera from the chuck-will's-widow, type of Antrostomus, in not having the rictal bristles garnished with lateral filaments, and is not very obviously difierent from Capri- mulgus t)f the Old World, it may be best to keep it with Antrostomus, where all the New Worl
