ID tip

Ruffed grouse are chunky, medium-sized birds that weigh from 450–750 g (0.99–1.65 lb), measure from 40 to 50 cm (16 to 20 in) in length, and span 50–64 cm (20–25 in) across their short, strong wings. They have two distinct morphs - grey and brown. In the grey morph, the head, neck, and back are grey-brown; the breast is light with barring, with as much white on the underside and flanks. Overall, the birds have a variegated appearance; the throat is often distinctly lighter. The tail is essentially the same brownish grey, with regular barring and a broad black band near the end ("subterminal").

About the Ruffed Grouse

The ruffed grouse is a medium-sized grouse occurring in forests from the Appalachian Mountains across Canada to Alaska. It is the most widely distributed game bird in North America. It is not migratory. It is the only species in the genus Bonasa. The ruffed grouse is sometimes incorrectly referred to as a "partridge", an unrelated phasianid, and occasionally confused with the grey partridge, a bird of open areas rather than woodlands.
