The buntings are a group of Old World passerine birds forming the genus Emberiza, the only genus in the family Emberizidae. The family contains 44 species. They are seed-eating birds with stubby, conical bills.
The tanagers comprise the bird family Thraupidae, in the order Passeriformes. The family has a Neotropical distribution and is the second-largest family of birds. It represents about 4% of all avian species and 12% of the Neotropical birds.
The fox sparrow is a large New World sparrow. It is the only member of the genus Passerella, although some authors split the species into four.
Pipilo is a genus of birds in the American sparrow family Passerellidae. It is one of two genera containing birds with the common name towhee.
LeConte's sparrow, also known as LeConte's bunting, is one of the smallest New World sparrow species in North America.
The genus Spizella is a group of American sparrows in the family Passerellidae.
Ammodramus is a genus of birds in the family Passerellidae, in the group known as American sparrows. Birds of this genus are known commonly as grassland sparrows. The name Ammodramus is from the Greek for "sand runner".
The nine-primaried oscines is a group of bird families in the suborder Passeri (oscines) of the Passeriformes. The composition of the group has changed since the term was introduced but is now considered to consist of seven major families—Fringillidae, Emberizidae, Cardinalidae, Thraupidae, Passerellidae, Parulidae and Icteridae—plus some small families. When Fringillidae is omitted the remaining six families are referred to as the "New World" nine-primaried oscines.
Haplospiza is a small genus of birds in the tanager family Thraupidae. Formerly classified in the bunting and American sparrow family Emberizidae, more recent studies have shown it to belong in the Thraupidae. Its two members breed in subtropical or tropical moist forest in Central and South America. They are often associated with bamboo.
Catamenia is a genus of atypical seedeaters. Formerly placed in the Emberizidae, they are now placed in the tanager family Thraupidae.
Coryphospingus is a small genus of finch-like tanagers found in South America. Coryphospingus was formerly classified in the family Emberizidae along with the buntings and American sparrows.
Embernagra is a genus of South American finch-like birds in the tanager family Thraupidae.
The Inca finches form the genus Incaspiza, of finch-like birds in the tanager family Thraupidae. They were traditionally placed in the family Emberizidae, but molecular phylogenetic studies have shown that they belong in Thraupidae instead. Both their scientific and common name refer to the Incan civilization.
Arremon is a genus of neotropical birds in the family Passerellidae. With the exception of the green-striped brushfinch which is endemic to Mexico, all species are found in South America, with a few reaching Central America.

Camarhynchus is a genus of birds in the tanager family Thraupidae. All species of Camarhynchus are endemic to the Galápagos Islands, and together with related genera, they are collectively known as Darwin's finches. Formerly classified in the bunting and American sparrow family Emberizidae, more recent molecular genetic studies have shown it to belong in the tanager family.
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. As of July, 2017, the American Ornithological Society assigns the genus to the new family Passerellidae, which contains the New World sparrows.
The moustached brushfinch is a species of bird in the family Passerellidae.
Peucaea is a genus of American sparrows. The species in this genus used to be included in the genus Aimophila.

Nearly 892 species belong to this group as it includes buntings, American sparrows, the New World blackbirds, the parulid warblers, the cardinals, and the tanagers.
