Ptarmigan are cold-region grouse in the genus Lagopus, known for their feathered feet and seasonal plumage changes from white in winter to mottled brown or gray in summer. They inhabit Arctic, subarctic, and alpine habitats across the Northern Hemisphere, including species such as the rock ptarmigan, willow ptarmigan, and white-tailed ptarmigan.

Taxonomy and naming

Ptarmigan are members of the grouse family Tetraonidae in the genus Lagopus. The term is used broadly for several closely related species rather than one single bird.

Physical characteristics

Ptarmigan are distinguished by feathered feet and, in many species, a seasonal shift to white winter plumage. Their feathers and body structure help them retain heat in harsh environments.

Habitat and range

Ptarmigan inhabit Arctic, subarctic, and alpine regions across the Northern Hemisphere. Different species occupy tundra, mountain slopes, and higher-elevation habitats.

Behaviour and ecology

Ptarmigan feed on shrubs, lichens, leaves, and other low-growing plants, and they often burrow into snow for shelter. They nest on the ground and rely on cryptic plumage for camouflage.

In Canada

Ptarmigan are part of Canadian northern and alpine wildlife. The rock ptarmigan is the official bird of Nunavut and the official game bird of Newfoundland and Labrador.

Key facts

  • Ptarmigan are grouse of the genus Lagopus found in cold northern and mountain environments.
  • They have fully feathered feet, an adaptation to cold conditions.
  • Many ptarmigan species change to white plumage in winter and mottled brown or gray in summer.
  • In North America, commonly recognized species include willow ptarmigan, rock ptarmigan, and white-tailed ptarmigan.
  • They nest on the ground and are adapted to browsing low vegetation and surviving snowy winters.
