"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

Adult male: Assuming stone-gray as the ground-color of the upper parts: Crown with a purplish cast, heavily dashed lengthwise with black; back darker, with smaller streaks; tail beautifully marbled with slate-gray and black tending crosswise on the 4 middle feathers; scapulars with bold black centre-fields set in frosty marbling; hind neck with white specks, as if continued around from the white throat-bar. Primaries black, with a little marbling at their ends, fully broken-barred with tawny-reddish; no white spaces. Three lateral tail-feathers mostly black, with pure white terminal spaces 1-2 inches long. Under parts quite blackish, on the breast powdered over with hoary-gray, more posteriorly marbled with gray and tawny, tending crosswise. Lores and ear-coverts dark brown. It is only in perfect plumage that the colors are as slaty and frosty as described; ordinarily more brown and ochrey." Elliot Coues, 1884
