Society Finch
It exists only in captivity: there is no wild society finch anywhere. Bred as a foster parent, and it will raise the chicks of other finch species.
Overview
The society finch, also called the Bengalese, is a domesticated bird with no wild population at all. It was developed in Asia from wild munias several hundred years ago, and there is nothing in nature to compare it to.
That shows in its temperament. Society finches are the calmest, most tolerant, most reliable finches kept, and they are the standard recommendation for a first finch and the standard foster parent for other species' eggs.
Temperament
Peaceable to an unusual degree. Society finches get on with each other, get on with other finch species, and rarely fight over anything.
They are famously good parents, which is why breeders use them to raise Gouldian and other finch chicks that the biological parents will not reliably rear. Same sex pairs bond and sit together happily, and the species is difficult to sex by sight, which most keepers discover when a pair produces no eggs and turns out to be two males.
Care and grooming
A quality finch seed mix, greens, egg food during moult and breeding, cuttlebone and grit. They are forgiving about diet compared to a Gouldian, which is part of why they are recommended first.
They are hardy across a wide temperature range and less prone to the respiratory problems that trouble more delicate finches. Claws grow quickly and want checking, because that is the one routine job a finch keeper actually has.
Living and exercise
30 by 18 by 18 inches for a small group, width over height, with perches at the ends and open flight between.
They breed readily and will keep doing so, which is worth deciding about in advance. Nest removal or same sex grouping are the two ways to stop it, and a pair left with a nest box will fill an aviary faster than anyone plans for.
