Willow Ptarmigan Facts

Ptarmigan are arctic grouse. The willow ptarmigan (Lagopus lagopus) changes color from light brown in summer to snow white in winter for effective camouflage from predators. Another distinctive feature is its feathered toes. In winter months the willow ptarmigan eats mosses and lichens, willow buds and twigs, a little birch; seeds and berries when available. In summer their diet expands to vegetable matter and occasionally caterpillars or beetles.

Ptarmigan are sociable in winter and usually feed and roost in the snow close together. In spring flocks of several thousand sometimes appear en route to their breeding grounds. These huge flocks rapidly disperse as summer areas are reached and cocks demand elbow room for their share of the tundra.
