It also can be found natively in Indonesia and Timor-Leste. The bird has been introduced to Puerto Rico, Portugal and the U.S..

The ground-dwelling Zebra Finch grows to a size of about 10 centimetres (3.9 in) long and prefers to eat grass seeds. This species' vocalizations consist mostly of chattering trills and calls.
