White-winged Snowfinch

The white-winged snowfinch, Montifringilla nivalis, presents itself as a robust, somewhat large snowfinch, measuring between 16.5 to 19 centimeters in length. Its plumage is a study in contrast, with brown adorning its upperparts and a pristine white cloaking its underparts. The head is a dignified grey, and one cannot miss the striking long, narrow white panel gracing each wing.

Identification Tips

Upon closer inspection, one notes the seasonal variations in this bird's appearance. During the summer months, the snowfinch boasts a jet-black bill and a similarly colored bib, which it sheds in winter. As the colder weather sets in, the bill takes on a yellow hue. In flight, the bird reveals black wings with expansive white panels and a black tail edged in white. Both sexes share a similar appearance, making them indistinguishable in the field.
