Breeding on the mountain plateau are ptarmigan, dotterel and snow bunting.
There are many wide stretches of country to which people can go—where hikers can walk, where campers can camp, where ski-iers can ski and throw down sandwiches for the ptarmigan.
Ptarmigan has cost us about £1·25 billion.
Ptarmigan and ravens are considered the only year-round birds in the park, although 43 different species make seasonal use of the area.
The summer plumage is browner and in the winter, the male willow ptarmigan lacks the rock ptarmigan's black stripe between the eyes and bill.
Wildlife in the area includes pika, cougar, mule deer, elk, marmot, coyote, ptarmigan, and gray jay.
Some of the common birds are ptarmigan, sea eagles, seagulls, and cormorants (coast).
Certain birds such as the eider duck, guillemot and ptarmigan are hunted for food in the winter.
