This finch was originally native to Java and Bali, in Indonesia. However, this bird has been a popular cage bird for centuries and the Java sparrow has now become established in many parts of the world, from Asia to Australia, Africa and North America. Trade in the bird is now banned except in a few countries such as China, Japan and Taiwan.
Male and female Java sparrows are equally pretty. However, it is easy to distinguish a male from a female as only the cock bird sings. He begins with single notes, like a bell, before developing into continuous trilling and clucking, mixed with high-pitched and deep notes.
