Grouse

Grouse: are a group of birds from the order Galliformes. They are sometimes considered a family Tetraonidae, though 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, from 83° North (Rock Ptarmigan in northern Greenland) to 28° North (Attwater's Prairie Chicken in Texas). Presumably they evolved in this zone. Grouse are heavily built like other Galliformes such as chickens. They range in length from 31 cm (12 in) to 95 cm (37 in), in weight from 0.3 kg (11 oz) to 6.5 kg (14 lb).
