Small brown finch of open highland steppes on the Tibetan plateau. Male has short but prominent black mustache and a dark bill. Female lacks the mustache, but has an orange bill and a pale white eyebrow stripe faintly resembling that of female and immature House Sparrows. Flashing white wing patches are only prominent when in flight. Confusingly, the Black-winged Snowfinch (Montifringilla adamsi) is occasionally referred to as the Tibetan Snowfinch in older field guides.
