Editing Australian zebra finch (section)

==Taxonomy and phylogeny==
The Australian zebra finch was described in 1837 by [[John Gould]] as ''Amadina castanotis'', about two decades after the [[Sunda zebra finch]] (''T. guttata'') was described.<ref name="Zannxiii–xiv">{{harvnb|Zann|1996|pp=xiii–xiv}}</ref> For over a century and a half, the Australian and Sunda zebra finches were classified as a single species, ''Taeniopygia guttata''. They were split by the [[IUCN Red List]] and [[BirdLife International]] in 2016. The [[International Ornithologists' Union|International Ornithological Congress]] followed suit in 2022 based on studies noting differences in plumage, [[Mitochondrial DNA|mtDNA]] divergence, and [[assortative mating]] between both species in captivity.<ref>{{Cite web|title=IOC World Bird List 12.1|url=https://doi.org/10.14344/IOC.ML.12.1|access-date=2022-01-29|website=IOC World Bird List Datasets|language=en-US|doi=10.14344/ioc.ml.12.1|s2cid=246050277 }}</ref><ref>{{Cite journal|last1=Olsson|first1=Urban|last2=Alström|first2=Per|date=2020-05-01|title=A comprehensive phylogeny and taxonomic evaluation of the waxbills (Aves: Estrildidae)|journal=Molecular Phylogenetics and Evolution|language=en|volume=146|pages=106757|doi=10.1016/j.ympev.2020.106757|pmid=32028027 |s2cid=211048731 |issn=1055-7903|doi-access=free|bibcode=2020MolPE.14606757O }}</ref>

It is likely that the Australian zebra finch evolved first, with the Sunda zebra finch descending from Australian zebra finches blown out to sea during the [[Pleistocene]].<ref name="Zann9–102">{{harvnb|Zann|1996|pp=9–10}}</ref>
