Also known as Java finch, Java rice sparrow or Java rice bird or Pipit Labuan by local is a small passerine bird. Some taxonomists place this and the Timor sparrow in their own genus Padda. Both sexes are similar. Immature birds have brown upperparts and pale brown underparts, and a plain head. 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.
In Labuan Island itself ait is very difficult to find this aves due to their natural habitat loss.
