"Pediaecetes phasianellus Columbianus. Common Sharp-tailed Grouse. Upper parts closely and pretty evenly variegated with blackish-brown, reddish-brown, and grayish-brown, the pattern smallest on the rump and lower back, where the blackish is mostly in sharp-angled stars; the reddish most conspicuous on the upper back, and both the lighter colors everywhere finely sprinkled with blackish. Wing-coverts like the upper back, but with numerous conspicuous rounded white spots, one on the end of each feather. Crown and back of neck nearly like the back, but in smaller pattern, and the markings mostly transverse. An illy-defined white area on each side of the neck, over the tympanum, and slight whitish stripe behind the eye. Throat fine light buff, usually immaculate, but sometimes finely speckled quite across. Under parts white, more or less tinted with buff towards the throat; the breast with numerous regular dark-brown U-shaped spots, one on each feather; similar but smaller, sharper, and fewer such spots thence scattered over most of the under parts, only the middle of the belly being left unmarked. Long feathers of the sides under the wings matching the upper wing-coverts nearly; under wing-coverts and axillaries pure white, not marked; flanks with bars or U-spots of dark brown. Legs grayish-white, unmarked. Quills of the wings fuscous; outer webs of the secondaries with equidistant, squarish, white or tawny spots, the secondaries tipped and imperfectly twice or thrice barred with white, gradually becoming sprinkled with the varied colors of the back, so that the innermost of them are almost precisely like the greater coverts. Four middle tail-feathers variegated, much like the back; others white, or grayish-white, on the inner webs, the outer webs being mottled; a few under tail-coverts spotted, the rest white; upper tail-coverts nearly like the rump. Iris light brown; bill dark horn-color; part of under mandible flesh-colored; claws like bill; toes on top light horn-color, the soles darker." Elliot Coues, 1884
