"Buteo vulgaris. hawk of Europe, Upper parts dark brown, very variable in shade according to season or wear of the feathers, varied with paler brown, or even reddish-brown edging of the feathers, but without the clear fawn color of the young; the feathers of the crown showing whitish when distributed, and usually sharp, dark shaft-lines; the upper tail-coverts chestnut and white, with blackish bars. Quills and tail-feathers as below, but the inner webs of the former showing more decided dark cross-bars upon a lighter marbled-whitish ground, and the latter having broader and sharper, dark wavy bars. These large quills, and particularly those of the tail, vary much in shade according to wear, the new feathers being strongly slate-colored, the old ones plain dark brown. The tail, however, never shows any trace often rich chestnut that obtains in the adult B borealis. Iris brown, never yellow; feet, cere, gape, and base of under mandible rich chrome-yellow; rest of bill and claws bluish-black." Elliot Coues, 1884

Black spots on some of the scapulars and wing-coverts, most of which are colored to correspond with the back, the larger ones being rather bluish-plumbeous. Lateral tail-feathers plumbeous-bluish, crossed with a black bar, the outer four on each side broadly ended with white. Bill black; angle of mouth carmine; iris brown; bare skin around eye livid bluish; feet lake-red, drying dull yellowish." Elliot Coues, 1884
