Grouse

Grouse are from the order Galliformes which inhabit temperate and subarctic regions of the northern hemisphere. They are game and are sometimes hunted for food.

Males are often 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 vegetable food, but will also feed on insects, especially when feeding young.
