Ruffed grouse

Bonasa umbellus

The ruffed grouse is a medium-sized grouse occurring in forests from the Appalachian Mountains across Canada to Alaska. It is non-migratory.

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.

The ruffed grouse is the state bird of Pennsylvania, USA.
