O Calafate (Padda oryzivora ou Lonchura oryzivora) é um pássaro proveniente das ilhas de Bali, Java e Bawean, na Indonésia. Os nomes mais vulgares desta ave em inglês são Java Rice Finch e Rice Sparow'.
Foram introduzidos por marinheiros e viajantes em outros locais como Bornéu, China, Japão, Ilhas Fiji, Malásia e Filipinas. Por se alimentarem de arroz e aveia, prejudicavam as produções agrícolas e eram por isso exterminados aos milhares.
O nome do pássaro vem de calafetar, actividade realizada pelos operários da construção naval que preenchem as frestas dos barcos com estopa e betume, fechando-as bem. O Calafate constrói seu ninho de forma semelhante, que possui formato de bola, bem vedado e com uma única abertura.
Possuem diversas variações de cores e penas sedosas. São ativos e curiosos e na natureza vivem em bandos. Sua coloração original é a cabeça preta e branca, com o restante do corpo em dois tons de cinza. Com os cruzamentos selecionados encontramos uma grande variedade de cores, incluindo pássaros inteiramente brancos. Podem chegar aos 15 cm de comprimento.

The Java Sparrow is 17 cm in length. 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.
Both sexes are similar, but immature birds have brown upperparts and paler brown underparts and cheeks. The rest of their head is dark grey rather than black, and the bill is grey with a pink base.
The call is a chip, and the song is a rapid series of call notes chipchipchipchipchipchip.
The Java Sparrow is a very gregarious bird which feeds mainly on grain and other seeds. It frequents open grassland and cultivation, and was formerly a pest in rice fields, hence its scientific name. The nest is constructed in a tree or building, and up to eight eggs are laid.
The Java sparrow is considered to be a serious agricultural pest of rice. Due to ongoing habitat loss and hunting in some areas, the Java Sparrow is now uncommon in its native range. It is evaluated as Vulnerable on the IUCN Red List of Threatened Species and is listed on Appendix II of CITES.
The Java Sparrow was introduced in the Indian subcontinent, but it failed to become a successful resident on the Indian mainland although it has established a breeding population around Colombo, Sri Lanka. In the United States there a breeding population on several of the Hawaiian Islands, especially Oahu.
The Java sparrow has been a popular cage bird in Asia for centuries, first in China and then in Japan, frequently appearing in Japanese paintings and prints. Meiji-era writer Natsume Soseki wrote an essay about his pet Java sparrow. In the late 1960s and early 1970s the Java sparrow was one of the most popular cage birds in the United States until its import was banned. Today it remains illegal to possess in California because of a perceived threat to agriculture, although rice-dependent Asian countries like China, Taiwan and Japan have not regulated the bird.
In Asia the Java sparrow is most often raised almost from birth by human breeders and owners, and they become very tame and attached to humans. As such, they can be normally kept in relatively small cages, but let out for indoor exercise without their attempting to escape. In captivity, a variety of colorations have been bred, including white, silver/opal, fawn/isabel, pastel, cream and agate (which currently is rare within Europe captive specimens) along with the pied Java Sparrow (called the "sakura buncho" in Japan).
