The white-winged snowfinch (Montifringilla nivalis), or snowfinch, is a small passerine bird. Despite its name, it is a sparrow rather than a true finch.
The white-winged snowfinch is a large stocky snowfinch at 16.5–19 centimetres in length. It has brown upperparts, white underparts and a grey head. There is a long narrow white wing panel. In summer, the bill is black, and there is a black bib. The bib is lost in winter and the bill becomes yellow. Sexes are similar.
In flight, it shows black wings with huge white wing panels, and a white edged black tail. This bird has a chattering song with many trills, and variety of rolling or creaky calls.
