Caucasian snowcock

The Caucasian snowcock ("Tetraogallus caucasicus") is a snowcock in the pheasant family Phasianidae of the order Galliformes, gallinaceous birds.
It is native to the Caucasus Mountains, particularly the Western Caucasus, where it breeds at altitudes from 2000–4000 m on bare stony mountains. It nests in a bare ground scrape and lays typically 5-6 greenish eggs, which are incubated only by the female. Its food is seeds and vegetable matter. It forms small flocks when not breeding.
