Willow Ptarmigan in Winter

“Lagopus albus. Willow Grouse. Willow Ptarmigan. Bill very stout and convex, its depth at base as the distance from nasal fossa to tip; whole culmen 0.75; bill black at all seasons. Male and female in winter: Snow white; 14 tail feathers black, white-tipped; the middle pair (which most resemble and perhaps are true rectrices, having no after-shafts) together with all the coverts, one pair of which reach to end of tail, white; shafts of several outer wing-quills black; no black stripe on head.” Elliot Coues, 1884
