The rock partridge (Lagopus muta) is an alpine bird the size of a pigeon that lives at high altitudes, above trees and shrubs. Up there, at the border between high-altitude meadows and rocky areas, generally between 1800 and 2700 meters, going up beyond 3000 meters in summer and autumn.
The black grouse, also commonly known as the capercaillie (Lyrurus tetrix), is one of the species that make up the typical alpine fauna. The adult male has black plumage with metallic blue highlights, white-edged wings, a deeply forked "lyre-shaped" tail, and red wattles above the eyes, which become particularly prominent in spring. The female, smaller and with brown-mimetic plumage, blends in with the surrounding environment and is less conspicuous.
The 2011 calendar of the Orsiera Rocciavrè Nature Park and the Reserves of the Chianocco and Foresto Orrido is a tribute to the beauties of the Park.
