Finch - Systematics and Taxonomy

Systematics and Taxonomy

The taxonomic structure of the true finch family, Fringillidae, has been fairly disputed in the past, with some upranking the Hawaiian honeycreepers (Drepanidinae) as family Drepanididae and/or uniting the cardueline and fringilline finches as tribes (Carduelini and Fringillini) in one subfamily; the euphonious finches (Euphoniinae) were thought to be tanagers due to general similarity in appearance and mode of life until their real affinities were realized. In particular, North American authors have often merged the buntings and American sparrow family (Emberizidae) – and sometimes the bulk of the nine-primaried oscines – with the split-up Fringillidae as subfamilies of a single massive family. But the current understanding of Passeroidea phylogeny is better reflected in keeping the fundamental nine-primaried oscine clades as distinct families. However, Przewalski's "Rosefinch" (Urocynchramus pylzowi) is now classified as a distinct family, monotypic as to genus and species, and with no particularly close relatives among the Passeroidea.

Fossil remains of true finches are rare, and those that are known can mostly be assigned to extant genera at least. Like the other Passeroidea families, the true finches seem to be of roughly Middle Miocene origin, around 20-10 million years ago (Ma). An unidentifable finch fossil from the Messinian age, around 12 to 7.3 million years ago (Ma) during the Late Miocene subepoch, has been found at Polgárdi in Hungary.
