Grouse are a group of birds from the order Galliformes. Grouse inhabit temperate and subarctic regions of the northern hemisphere. They are game and are sometimes hunted for food.
In all but one species (the Willow Grouse), males are polygamous, and many species have elaborate courtship displays. These heavily built birds have legs feathered to the toes. Most species are year-round residents, and do not migrate.
These birds feed mainly on vegetation, but also on insects, especially when feeding young.
The American Ornithologists' Union includes grouse (Tetraonidae) as a subfamily of Phasianidae. Based on mtDNA sequences, some systematists believe that certain species belong in new genera.[1]
