I saw this Male in breeding plumage at about 12,000 feet. Notice how camouflaged it is. They are very tame and allow close approach, if you can find them. White-tailed Ptarmigan were introduced in the 70's by the DWR to the Uintas, but there were reports of them before that up here, but none fully document because they were seen by stock men, about the only people who came up here before the 70's. Now they are found throughout the alpine zone of the Uintas. They are definitely native to the White River Plateau in Colorado just a hundred or so miles to the east.
