This Munia is found only in Java, Bali, Lombok and southern Sumatra. However, Munias are popular cage-birds and some are supposed to have escaped in Singapore and become feral there. However, I have yet to see one in that country. Sad to say, they are regarded as pests by the rice farmers because, as you can see here, they do ravage their padi.
