"Buteo borealis. Red-tailed Buzzard. "Hen Hawk". Upper surface of tail rich chestnut, with white tip and usually a black subterminal zone, with or without other narrower and more or less imperfect black bars; sometimes barred throughout. From below, the tail appears pearly whitish with a reddish tinge, wither quite uniform, or barred throughout with the whitish and blackish. In general, it is the female with the most barred or completely barred tail, the male with the uniform tail, only subterminally once-zoned. Upper parts blackish-brown, with a thoroughly indeterminate amount of light variegation, gray, fulvous, and whitish; feathers of hind head and nape with cottony white bases, showing when disturbed; those of hind neck usually with fulvous edging; of scapular region showing most variegation with tawny or whitish, or both, the scapulars and adjoining feathers being largely barred, and only blackish on their exposed portions; upper tail-coverts showing much tawny and white. Ground color of under parts white, more or less buff-toned, the dark color of the upper parts reaching nearly or quite around the throat, the flanks and lower belly heavily marked with dark brown or blackish, but a large pectoral area, with the tibiae and crissum, mostly free from markings, as a rule; but no description will cover the latitude of coloration. Primaries blackening on their exposed portions, for the rest lighter grayish-brown, dark-barred across both webs, and extensively white-areated on inner webs basally." Elliot Coues, 1884

"Astur atricapillus. American Goshawk. Blue Hen Hawk (adult). Chicken Hawk (young). Adult: Above, dark bluish-slate color, each feather black-shafted; top of head blackish, conspicuously different from other upper parts, the feathers there with fleecy white bases; a long white superciliary or rather post-ocular stripe; auriculars blackish. Ground color of under parts, including lining of wings, white, closely barred or vermiculated in narrow zigzag lines with slaty-brown, except on throat and crissum, and everywhere sharply pencilled with blackish shaft-lines, one on each feather. The barring is largest and most regular on the belly, flanks, and tibiae, but is for the most part much dissipated in a fine mottling. It varies greatly in coarseness in different specimens, some of which approach A. palumbarius in this respect. Tail like back, banded with four or five blackish bars, the terminal one much the broadest. Bill dark bluish; iris yellowish; feet yellow, claws black." Elliot Coues, 1884

"Circus cyaneus hudsonius. American Marsh Hawk, Harrier. Blue hawk. Adult Male: In perfect plumage pale pearly-bluish, or bluish-ash, above, with the upper tail-coverts entirely pure white; but most specimens have a dusky wash obscuring the bluish, and retain traces of brown or rufous. Five outer primaries mostly blackish, all of them and the secondaries with large white basal areas on inner webs; tail-feathers banded with 5 or 6 obscure dusky bars, the terminal one strongest and most distinct, and marbled with white toward their bases. The bluish cast invades the fore under parts, the rest of which are white, with sparse drop-shaped rufous spots; lining of wings white. From this blue-and-white state the bird is found grading by degrees into the very different plumage of the female and young: Above, dark umber-brown, everywhere more or less varied with reddish-brown or yellowish-brown, the upper tail-coverts, however, white, forming a very conspicuous mark; under parts a variable shade of brownish-yellow, or ochraceous, streaked with umber-brown, at least on breast and sides; tail crossed with 6-7 blackish bars."
