Sometimes called the Partridge, the Ruffed Grouse is one of 10 species of grouse native to North America, ranging mostly in regions where snow is an important part of the winter scene (consistently covering the ground from late November to at least late March). The Ruffed Grouse is a hearty bird which thrives during severe winters that decimate flocks of quail, pheasants, and turkeys.
