The Australian zebra finch (Taeniopygia castanotis)[2] 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.[1] 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.[3]

The zebra finches are two species of estrildid finch in the genus Taeniopygia found in Australia and Indonesia. They are seed-eaters that travel in large flocks.

The Sunda zebra finch (Taeniopygia guttata) is a species of bird in the family Estrildidae. It is found in the Lesser Sundas.

The red-browed finch (Neochmia temporalis) is an estrildid finch that inhabits the east coast of Australia. This species has also been introduced to French Polynesia. It is commonly found in temperate forest and dry savannah habitats. It may also be found in dry forest and mangrove habitats in tropical regions.

The double-barred finch (Stizoptera bichenovii) is an estrildid finch found in dry savannah, tropical (lowland) dry grassland and shrubland habitats in northern and eastern Australia. It is sometimes referred to as Bicheno's finch or as the owl finch, the latter of which owing to the dark ring of feathers around the face. It is the only species placed in the genus Stizoptera .

The Society finch (Lonchura striata domestica), also known as the Bengali finch  or Bengalese finch, is a domesticated subspecies of estrildid finch. It became a popular cage and trade bird after appearing in European zoos in the 1860s through being imported from Japan, though it was domesticated in China. Coloration and behavior were modified through centuries of selection in Asia, then later in Europe and North America.[1]
