The Gouldian finch was described by British ornithologist John Gould in 1844 as Amadina gouldiae, [3] in honour of his deceased wife Elizabeth. [4] [5] Specimens of the bird were sent to him by British naturalist Benjamin Bynoe, although they had been described some years before by French naturalists Jacques Bernard Hombron and Honoré Jacquinot.

Sarah Rosalind Pryke is a behavioural and evolutionary ecologist. [1] [2] A graduate of the University of Natal (South Africa), with a PhD from Göteborg University (Sweden), she is best known for her research on the evolution of sexual signals in the Red-collared widowbird and more recently research on maternal effects and the evolution of alternative reproductive strategies in the Gouldian ...
A group of researchers investigated how the survival rates of offspring of Erythrura Gouldiae (Gouldian finch) are impacted when the mating pair have genes for different colors. [9] They bred both pure and mixed pairs of the finches (in this species the gene for producing a red-headed finch is dominant to the one that produces a black headed ...

Alternatively, the distribution of male and female tissue can be more haphazard. Bilateral gynandromorphy arises very early in development, typically when the organism has between 8 and 64 cells. [25] Later stages produce a more random pattern. [citation needed] A notable example in birds is the zebra finch.
Estrildidae, or estrildid finches, is a family of small seed-eating passerine birds of the Old World tropics and Australasia.They comprise species commonly known as munias, mannikins, firefinches, parrotfinches and waxbills.
The female is the brighter of the sexes and initiates courtship. The male incubates the eggs and tends the young. ... Gouldian finch, Chloebia gouldiae; Scaly ...
The eggs are incubated for 11–13 days by the female, who is fed by the male. The chicks are fed by both parents. Initially they receive a mixture of seeds and insects, but as they grow the proportion of insect material decreases. [25] For the first 7–9 days the young are brooded by the female. The nestlings fledge 13–18 days after hatching.
