A small bird with a green back, purple breast and yellow belly.
Adults have a green back, purple breast and yellow belly. Face colour varies, including black and red, and males are brighter than females.
Gouldian Finches nest in tree cavities. An Australian study compared nesting density with habitat features at two scales. Across a landscape of about 60 square kilometres, the abundance of suitable nest sites was the strongest predictor of where nests were concentrated. At a finer scale of about one square kilometre, no single measured factor explained nest locations.
Breeding habitat may therefore depend both on landscapes that retain clusters of cavity-bearing trees and on the shape of individual hollows. The research highlights a breeding requirement that can be missed when attention focuses only on feeding grounds. It compared habitat patterns; it did not prove that adding cavities alone would increase the population.
IUCN Red List · Least Concern (LC) · Global
The IUCN Red List assessed the Gouldian Finch as Least Concern globally in 2022, with a stable trend. Under Australia’s Environment Protection and Biodiversity Conservation Act, however, it is listed as Endangered and has a national recovery plan. The global assessment and Australia’s legal listing have different geographic and legal scopes. Retaining old trees with natural nesting cavities and the surrounding habitat is an important part of domestic recovery planning.
