Ptarmigan Stock Video Footage


ptarmigan

The three species are all sedentary specialists of cold regions. Willow ptarmigan is a circumpolar boreal forest species, white-tailed ptarmigan is a North American alpine bird, and rock ptarmigan breeds in both Arctic and mountain habitats across Eurasia and North America. With the exception of the red grouse, all have a white winter plumage that helps them blend into the snowy background. Even their remiges are white, while these feathers are black in almost all birds (even birds that are predominantly white, such as the Bali myna) because melanin makes them more resilient and thus improves flight performance. The Lagopus grouse apparently found it easier to escape predators by not being seen than by flying away. These are hardy vegetarian birds, but insects are also taken by the developing young. In all species except for the willow ptarmigan, the female takes all responsibility for nesting and caring for the chicks, as is typical with gamebirds.
