The smallest grouse in North America, the White-tailed Ptarmigan inhabits alpine regions from Alaska to New Mexico. It has numerous adaptations to its severe habitat, including feathered toes, highly cryptic plumage, and an energy-conserving daily regime.
Clucks at various rates. In breeding season, males issue clucks, chatters, and loud cries in flight and on the ground.
