Which locations host established, thriving populations of *introduced* zebra finches outside of their native Oceania and Indonesian range?
USA, Brazil, Portugal, and Puerto Rico
Although the native distribution of the zebra finch genus is confined primarily to Australia and the Lesser Sunda Islands, their adaptability has allowed them to establish feral or introduced populations successfully in several other regions globally, usually facilitated by human introduction. Specifically, there are documented, thriving, and established populations of these introduced finches noted in the USA and Brazil. Furthermore, the text mentions that a small feral population has managed to survive in Portugal, and another source explicitly points to their introduction in Puerto Rico. Despite these established non-native communities, the IUCN classifies both species within the genus *Taeniopygia* as Least Concern (LC) regarding global survival status.
