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]
