Rock ptarmigan

The rock ptarmigan is also an arctic-alpine species. It is beholden to the moraines, screes, and short grasslands at high altitude. It is part of the mountain galliformes such as the black grouse, the hazel grouse or the rock partridge dear to Marcel Pagnol. To adapt to the rigours of winter, it trades its summer grey plumage for an entirely white plumage, has claws covered entirely in feathers and, takes shelter in a snow igloo during intense cold periods.
