Traditionally considered a bunting and placed in the family Emberizidae, it is actually neither a bunting nor a true finch, but belongs to a group of finch-like birds or tanager-finches in the family Thraupidae.
The Inaccessible Island Finch (Nesospiza acunhae) is a species of bird in the Thraupidae family (formerly in Emberizidae).
The Nightingale Island Finch (Nesospiza questi) is a species of bird in the Thraupidae family (formerly in Emberizidae).
The Abert's Towhee (Melozone aberti) is a bird of the family Emberizidae, native to a small range in southwestern North America, generally the lower Colorado River and Gila River watersheds, nearly endemic to Arizona, but also present in small parts of California, Nevada, Utah, New Mexico, and Sonora in Mexico.
In late 20th century sources in particular, it was very often allied to the American sparrows and placed in the Emberizidae family.
