Passerellidae
New World sparrows are a group of mainly New World passerine birds, forming the family Passerellidae. They are seed-eating birds with conical bills, brown or gray in color, and many species have distinctive head patterns. Although they share the name sparrow, New World sparrows are more closely related to Old World buntings than they are to the Old World sparrows (family Passeridae). New World sparrows are also similar in both appearance and habit to finches, with which they sometimes used to be classified. Taxonomy The genera now assigned to the family Passerellidae were previously included with the buntings in the family Emberizidae. A phylogenetic analysis of nuclear and mitochondrial DNA sequences published in 2015 found that the Passerellidae formed a monophyletic group that had an uncertain relationship to the Emberizidae. Emberizidae was therefore split and the family Passerellidae resurrected. It had originally been introduced, as the subfamily Passerellinae, by the Ger ...

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.

Spizelloides
The American tree sparrow (''Spizelloides arborea''), also known as the winter sparrow, is a medium-sized New World sparrow. Taxonomy In 2014, the American tree sparrow was moved to its own monotypic genus, ''Spizelloides'', from genus ''Spizella'', based on polyphyly in ''Spizella'' and multilocus molecular evidence suggesting the species was strongly divergent from other extant genera. Description The bird's measurements are as follows: * Length: 5.5 in (14 cm) * Weight: 0.5–1.0 oz (13–28 g) * Wingspan: 9.4 in (24 cm) Adults have a rusty cap and grey underparts with a small dark spot on the breast. They have a rusty back with lighter stripes, brown wings with white bars and a slim tail. Their face is grey with a rusty line through the eye. Their flanks are splashed with light brown. They are similar in appearance to the chipping sparrow. Distribution and habitat Their breeding habitat is tundra or the northern limits of the boreal forest in Alaska and ...

Chlorospingus
''Chlorospingus'' is a genus of perching birds, the bush tanagers, traditionally placed in the tanager family (Thraupidae). More recent studies which suggest they are closely related to the genus '' Arremonops'' in the Passerellidae (American sparrows). As of July, 2017, the American Ornithological Society assigns the genus to the new family Passerellidae, which contains the New World sparrows. It contains the following species: The taxonomy and systematics of the common bush tanager are under review; it appears to be a superspecies In biology, a species complex is a group of closely related organisms that are so similar in appearance and other features that the boundaries between them are often unclear. The taxa in the complex may be able to hybridize readily with each oth ... or even a complex of superspecies.
