The Java sparrow (Lonchura oryzivora; Japanese: 文鳥, bunchō), also known as the Java finch, Java rice sparrow or Java rice bird, is a small passerine bird. [3] 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 into many other countries.
They are also known as true sparrows, a name also used for a particular genus of the family, Passer. [1] They are distinct from both the New World sparrows, in the family Passerellidae, and from a few other birds sharing their name, such as the Java sparrow of the family Estrildidae.
The genus Padda was introduced in 1850 by the German naturalist Ludwig Reichenbach for the Java sparrow. [1] [2] The word "Padda" was used as an English name for the Java sparrow by George Edwards in 1743 and may come from the Malay word padi meaning "rice".

Alternatively, the distribution of male and female tissue can be more haphazard. Bilateral gynandromorphy arises very early in development, typically when the organism has between 8 and 64 cells. [25] Later stages produce a more random pattern. [citation needed] A notable example in birds is the zebra finch.
Forty-four are called brushfinches and the remaining 27 have a variety of other names. The North American and South American classification committees of the American Ornithological Society (AOS) and the Clements taxonomy recognize fewer species, BirdLife International 's Handbook of the Birds of the World recognizes more, and all three also ...
When male and female birds of such species copulate, they each evert and then press together, or "kiss" their respective proctodeum (the lip of the cloaca). Upon the clocal kiss, the male's sperm spurts into the female's urodoeum (a compartment inside the cloaca), which then make their way into the oviduct. [104] [105] clutch
