The snow partridge is found is small groups, usually about 6 to 8 but up to 30 during the non-breeding season. When flushed, they usually fly up before scattering away with noisy wing beats. The flight is rapid and stirring. It has a habit of sunning itself on rocks during the midday. The call in the breeding season is said to resemble that of the grey francolin of the plains. It has been compared in habit to that of the ptarmigan. It is said to feed on mosses, lichens, berries, and the shoots of plants. It also swallows grit to aid digestion.
