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.
[10] [11] [4] The hedge sparrow or dunnock (Prunella modularis) is similarly unrelated. It is a sparrow in name only, a relict of the old practice of calling more types of small birds "sparrows". [12] A few further bird species are also called sparrows, such as the Java sparrow, an estrildid finch.
[2] [3] The type species was subsequently designated as the house sparrow (Passer domesticus). [3] [4] The name Passer is the Latin word for "sparrow."

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".
The family Estrildidae was introduced in 1850 by the French naturalist Charles Lucien Bonaparte as "Estreldinae", a spelling variant of the subfamily name. [2] [3] In the list of world birds maintained by Frank Gill, Pamela Rasmussen and David Donsker on behalf of the International Ornithological Committee (IOC) the family contains 140 species divided into 41 genera.

While CASI establishes the foundational sex identity of a cell, hormones can modulate the expression of CASI-driven traits. For instance, in birds, male and female somatic cells may exhibit intrinsic differences due to CASI, but the extent to which these differences manifest in tissues can be influenced by circulating hormones such as estrogen ...
Maluridae is a family of small, insectivorous passerine birds endemic to Australia and New Guinea. They are socially monogamous and sexually promiscuous, meaning that although they form pairs between one male and one female, each partner will mate with other individuals and even assist in raising the young from such pairings.
Its contrasting face pattern makes this species easily identifiable in all plumages; [4] the smaller size and brown, not grey, crown are additional differences from the male house sparrow. [2] Adult and juvenile Eurasian tree sparrows undergo a slow complete moult in the autumn, and show an increase in body mass despite a reduction in stored ...
