The genus Spizella is a group of American sparrows in the family Passerellidae.[1]

These birds are fairly small and slim, with short bills, round heads and long wings. They are usually found in semi-open areas, and outside of the nesting season they often forage in small mixed flocks.[1]
Systematics

This genus was formerly placed with the Old World buntings in the family Emberizidae.[1] However, genetic studies revealed that New World sparrows formed a distinct clade and thus it was placed in the resurrected family Passerellidae.[2][3]
Species

Chipping sparrow, Spizella passerina
Clay-colored sparrow, Spizella pallida
Brewer's sparrow, Spizella breweri
Timberline sparrow, Spizella breweri taverneri
Field sparrow, Spizella pusilla
Worthen's sparrow, Spizella wortheni
Black-chinned sparrow, Spizella atrogularis

The American tree sparrow, Spizelloides arborea, was formerly a member of this group, but is now placed in its own monotypic genus Spizelloides.[1]
