High Quality Content by WIKIPEDIA articles! The Snow Partridge (Lerwa lerwa) is a gamebird in the pheasant family Phasianidae found widely distributed across the high-altitude Himalayan regions of India, Pakistan, Nepal and China. It is the only species within the genus. The species is found in alpine pastures and open hillside above the treeline but not in as bare rocky terrain as the Himalayan Snowcock and is not as wary as that species. Males and females look similar in plumage but males have a spur on their tarsus.
