Uncommon to locally fairly common. Large game bird of upland moors and heathland, often near plantations of conifers. In early spring, males gather around dawn to display, fanning their deeply forked tails and fluffing their white undertail coverts. Male distinctive, with long, lyre-shaped tail and white undertail coverts; shows white wing stripe in flight. Female warm brown with heavy dark barring; compare to smaller and rustier "Red Grouse," (Willow Ptarmigan) which shows solidly dark tail in flight.
