Grouse

Grouse are a group of birds from the order Galliformes. Often considered a family Tetraonidae, the American Ornithologists' Union and many others include grouse as a subfamily Tetraoninae in the family Phasianidae. Grouse inhabit temperate and subarctic regions of the northern hemisphere, from pine forests to moorland and mountainside. Most species are year-round residents, and do not migrate.
