guttata is likely due to a Pleistocene glaciation event where the sea level dropped between about 100 and 150 metres (330 and 490 ft), putting the coasts of Timor and Australia closer. The present-day distribution of the species T. The zebra finches likely evolved in Australia, with either northern or southeastern Australia postulated as two places where the genus arose. It is placed in the tribe Poephilini, along with the genus Poephila, which it was previously included in the split between Taeniopygia and Poephila is justified by a 1987 study using protein electrophoresis and chromosomal banding. Its current genus, Taeniopygia, was described in 1862 by Ludwig Reichenbach. The Australian species was then described in 1837 by John Gould as Amadina castanotis. The Indonesian species was described in 1817 by Louis Jean Pierre Vieillot in his Nouveau Dictionnaire d'Histoire Naturelle, where he gave it the scientific name Fringilla guttata. The zebra finch was first captured in 1801 during Nicolas Baudin's expedition to Australia. The International Ornithological Congress followed suit in 2022 based on studies noting differences in plumage, mtDNA divergence, and assortative mating between both species in captivity. However, they were split by the IUCN Red List and BirdLife International in 2016. Previously, both species were classified as a single species, the zebra finch ( T.
They are seed-eaters that travel in large flocks. The zebra finches are two species of estrildid finch in the genus Taeniopygia found in Australia and Indonesia.
