Spizella
The genus ''Spizella'' is a group of American sparrows in the family Passerellidae. 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. Systematics This genus was formerly placed with the Old World buntings in the family Emberizidae. However, genetic studies revealed that New World sparrows formed a distinct clade and thus it was placed in the resurrected family Passerellidae.

Chipping Sparrow
The chipping sparrow (''Spizella passerina'') is a species of New World sparrow, a passerine bird in the family Passerellidae. It is widespread, fairly tame, and common across most of its North American range. There are two subspecies, the eastern chipping sparrow and the western chipping sparrow. This bird is a partial migrant with northerly populations flying southwards in the fall to overwinter in Mexico and the southern United States, and flying northward again in spring. It molts twice a year. In its breeding plumage it has orangish-rust upper parts, gray head and underparts and a distinctive reddish cap. In non-breeding plumage, the cap is brown and the facial markings are less distinct. The song is a trill and the bird has a piercing flight call that can be heard while it is migrating at night. In the winter, chipping sparrows are gregarious and form flocks, sometimes associating with other bird species. They mostly forage on the ground for seeds and other food items, a ...

Black-chinned Sparrow
The black-chinned sparrow (''Spizella atrogularis'') is a small bird in the genus ''Spizella'', in the New World sparrow family Passerellidae.
