The Java sparrow (Lonchura oryzivora), also known as Java finch, Java rice sparrow or Java rice bird, is a small passerine bird. This estrildid finch is a resident breeding bird in Java, Bali and Bawean in Indonesia. It is a popular cage bird, and has been introduced in a large number of other countries. Some taxonomists place this and the Timor sparrow in their own genus Padda. The Java sparrow is about 15 to 17 cm (5.9 to 6.7 in) in length from the beak to its tip of tail feathers. Although only about the size of a house sparrow, it may be the largest species in the estrildid family. The adult is unmistakable, with its grey upperparts and breast, pink belly, white-cheeked black head, red eye-ring, pink feet and thick red bill.
