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.

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.
