|Species:|| Erythrura gouldiae|
The Gouldian finch is a small bird with a bright green back, purple breast and yellow belly. In about 75% of the birds, the facial colour is black, red facial colour is found on 25% of the birds, and rare, yellow-faced birds occur from time to time. The yellow colour results from a lack of red pigment in the red-faced birds. Males are brighter in plumage than females. Young Gouldian Finches are dull ashy grey on the head and hind neck, becoming olive on the back and tail. The underparts are brown white, paler on chin, and have a faint yellow tinge on the belly. The upper bill is blackish and the lower bill is pinkish white. The end of the beak is tipped with red and there are pale nodules on the gape.
Distribution and HabitatEdit
The Gouldian Finch is patchily distributed in tropical northern sub-coastal areas from Derby, Western Australia, to the Gulf of Carpentaria and thinly to central Cape York Peninsula, but is locally common in the north and north-western parts of its range.
Found in small flocks.
Gouldian finches will pluck seeds from plants and grasses. They also eat insects. In captivity, their diet consist of Canary seed, millet, green seeds, live food such as mealworms.
Breeding and nestingEdit
Natural breeding occurs in November to April / December to March. Gouldian finches nest in trees and termite mounds. They are known to nest in the hollows of tress and log (These are great nest's for the vary). In the aviary they have specific needs and have found that nesting boxes with a longer tunnel or perhaps partition from main cavity is preferred. Ensure some softer nesting materials is added to the nest. Clutch sizes ranging from 4-8 egg. The young will will hatch after 12 to 14 days with young fledge at around 21 days. 
There is strong evidence of a continuing decline, even at the best-known site near Katherine in the Northern Territory. Large numbers are bred in captivity, particularly in Australia. In the state of South Australia, National Parks & Wildlife Department permit returns in the late 1990s showed that over 13,000 Gouldian finches were being kept by aviculturists. If extrapolated to an Australia-wide figure this would result in a total of over 100,000 birds. In 1992, it was classified as "endangered in the wild" under IUCN's criteria C2ai. This was because the viable population size was estimated to be less than 2,500 mature individuals, no permanent subpopulation was known to contain more than 250 mature individuals, and that a continuing decline was observed in the number of mature individuals. It is currently subject to a conservation program.
