Java sparrows (Lonchura oryzivora) are small members of the waxbill family. They are attractive, which makes them popular as pets. They are mostly grey with a pale pink belly fading to white just above the tail. Their head and tail are black with contrasting white cheeks and they have a large bright pink beak. They are also known as Java finch, Java rice sparrow or Java rice bird, and are resident breeding birds in Java, Bali and Bawean in Indonesia. Although native to Java and Bali, this species has been introduced to Malaysia, Fiji, the Caribbean and the United States due to escapes from domestic aviaries. Males perform a complex courtship dance involving bowing, jumping and singing.
