White-tailed ptarmigans. View of three white- tailed ptarmigans (Lagopus leucurus) sheltering under a shelf of snow. White-tailed ptarmigans live in the mountains of western North America,from Alaska to New Mexico. They eat leaves,buds and some insects. They are protected from the cold in their habitat by a thick layer of insulating feathers. In summer,their plumage turns brown to provide camouflage amongst scrub,just as this all-white plumage provides camouflage in the snow. They live in large flocks after the breeding season,and are a popular prey bird for a variety of carnivores | |
