The genus Spizella is a group of American sparrows in the family Passerellidae.[2]

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.[2]

Systematics

This genus was formerly placed with the Old World buntings in the family Emberizidae.[2] However, genetic studies revealed that New World sparrows formed a distinct clade and thus it was placed in the resurrected family Passerellidae.[3][4]

Species

The American tree sparrow, Spizelloides arborea, was formerly a member of this group, but is now placed in its own monotypic genus Spizelloides.[2]
