The Australian zebra finch is the most common estrildid finch of Central Australia. It ranges over most of the continent, avoiding only the cool humid south and some areas of the tropical far north. The bird has been introduced to Puerto Rico and Portugal. Due to the ease of keeping and breeding the zebra finch in captivity, it has become Australia's most widely studied bird; by 2010, it was the most studied captive model passerine species worldwide, by a considerable margin.
Region
Australia
Typical Environment
Occurs across most of mainland Australia, especially the arid and semi-arid interior, avoiding only the cool, humid far south and parts of the tropical far north. Prefers open habitats such as grasslands, shrublands, acacia and eucalypt savanna, and agricultural lands. Common along watercourses, stock dams, and around human settlements in the outback. Introduced populations exist in Puerto Rico and locally in Portugal.

The Australian zebra finch is one of the most studied birds in the world, serving as a key model for research on vocal learning, neuroscience, and behavior. It breeds readily in captivity and forms strong pair bonds, often nesting soon after rainfall in the wild. Although naturally restricted to Australia, it has been introduced to a few places such as Puerto Rico and Portugal.

Social Behavior
Often found in flocks and strongly gregarious outside the breeding season. Forms monogamous pairs that build domed grass nests in shrubs, trees, or human structures. Breeding is opportunistic and closely tied to rainfall, with colonies forming near reliable water.
Migratory Pattern
Nomadic
Song Description
Males deliver a short, variable song composed of soft buzzes, trills, and whistles, often repeated in stereotyped motifs. Both sexes give sharp 'tet' contact calls and soft chatter that keeps flocks coordinated.
Plumage
Compact finch with smooth grey upperparts and white underparts; bold black-and-white barring on the tail and rump. Males show zebra-like black barring on the throat and upper chest, chestnut ear patches, and chestnut flanks dotted with white. Females are plainer grey without the chestnut markings.
Diet
Primarily eats seeds of native and introduced grasses, including spinifex and millet-like seeds. Supplements the diet with small insects, especially during breeding to provide protein for nestlings. Also takes green shoots and the occasional fallen seed from agricultural areas.
Preferred Environment
Forages mostly on the ground in open areas with seeding grasses, along tracks, waterholes, and farmyards. Frequently visits the edges of dams and creeks to drink and feed.
