Black-winged Snowfinch Montifringilla adamsi adamsi is resident in southern Tibet (Himalayas) and southern Xinjiang (Kunlun Mountains), and xerophila occurs from Qilian Mountains in Gansu and Qinghai south to eastern Tibet and western Sichuan. Forages on ground at edges of snowfields between 3500 m and 5200 m. Similar to Henri’s snowfinch, but paler, with grey-brown not earth-brown head. Overall less contrasting than Henri’s, the lack of contrast being especially visible on head, on which submoustachial stripe is faint or absent, and on wings, which show less white (white broken by broad black bases of secondaries in open wing). Black, white-tipped bib also less prominent on Tibetan, being especially faint on overall paler ssp. xerophila. Female duller with browner wings and a smaller and less distinct (or completely imperceptible) bib. White-winged snowfinch (ssp. groumgrzimaili and kwenlunensis) has more white on wings, a more distinct bib and submoustachial stripe, and a darker grey head; also prefers slightly higher country. Juvenile Tibetan also recognized by wing pattern and paler head. Non-breeding bill horn-yellow with black tip. Breeding bill black. Feet black; iris brown. Utters distinctive, monotonous, single-note song from perch or during display flight. — Craig Brelsford
