Small, rather slender “finch” (actually a tanager!) with bright yellow-pink legs. The white band at base of tail is best seen in flight, when the tail is spread. Found in variety of open stony and sandy habitats with scattered bushes and grassy areas. Breeding male has bright yellow bill and blackish face. Nonbreeding male is duller with a pale eyering and pinkish bill. Female is best told by pale eyering and fine dark streaking above and below, as well as the white tail band, which can be hard to see.
