"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

"Falco mexicanus. American Lanner Falcon. Prairie Flacon. A medium-sized species, distinguished from any gyrfalcon by the smaller size, different feathering of the tarsus etc., from the duck hawk by the general much lighter color, which is dull brownish above instead of dark slate, etc. Adult: Upper parts brownish-drab, each feather with a paler border of brown, grayish, or whitish; the top of the head more uniform, the occiput and nape showing more whitish. Under parts white, everywhere excepting on the throat marked with firm spots of dark brown, most linear on the breast, then more broadly oval on the belly, enlarging and tending to merge into bars on the flanks, very sparse or obsolete on the crissum, on the maxiliary region forming a broad firm moustache; these marking corresponding with the ground color of the upper parts. Primaries ashy-brown, with narrow but firm pale edging of outer webs and ends, the inner webs regularly marked with white in form of barred indents or circumscribed spots, most numerous and regular on the outer primaries; the white tinged with fulvous, next to the shafts; the outer web of the first primary either plain, or with whitish indents as in F. lanarius; outer webs of secondaries more or less marked with fulvous; axillars plain dark brown; lining of wings otherwise white, spotted with dark brown. Tail pale brownish-gray, nearly uniform, but with white tip, and more or less distinct barring or indenting with whitish, especially on the lateral feathers, producing a pattern not unlike that of the primaries. Bill mostly dark bluish horn-color, but its base, and much of under mandible, yellow; feet yellow." Elliot Coues, 1884
