Siberian roe deer
Himalayan wolves prefer wild over domestic prey. They prefer the smaller Tibetan gazelle over the larger white-lipped deer, and they prefer the plains-dwelling Tibetan gazelle over the cliff-dwelling bharal. Supplementary food includes the small Himalayan marmot, woolly hare, and pikas. Himalayan wolves avoid livestock where wild prey is available, but habitat encroachment and the depletion of wild prey populations is expected to lead to conflict with herders. To protect them, securing healthy wild prey populations through setting aside wildlife habitat reserves and refuges is essential. Kiang, Siberian roe deer, Siberian ibex, Przewalski's horse, wild yak, argali, urial, markhor, Bactrian deer, Yarkand deer, and Tibetan red deer have also been recorded as prey species of Himalayan wolves.
