The Java Sparrow, Padda oryzivora also known as Java Finch, Java Rice Sparrow or Java Rice Bird is a small passerine bird. Both sexes are similar. Immature birds have brown upperparts and pale brown underparts, and a plain head. Very young birds have a black beak with a pink base.
The Java sparrow has been a popular cage bird in Asia for centuries, first in Ming Dynasty China and then in Japan from the 17th century, 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. 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.
