The zebra finch (Taeniopygia guttata [formerly Poephila guttata]), is the most common estrildid finch of Central Australia and ranges over most of the continent, avoiding only the cool moist south and some areas of the tropical far north. It can also be found natively in Indonesia and East Timor. The bird has been introduced to Puerto Rico, Portugal, Brazil and the United States.
The life expectancy of a zebra finch is highly variable because of genetic and environmental factors. The zebra finch may reach up to five years in its natural environment. If they are kept caged, they normally live for 5 to 9 years but may live as long as 12 years, with an exceptional case of 14.5 years reported for a caged specimen. The greatest threats to zebra finch survival are predation by cats and loss of natural food.
