[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.
In organisms where CASI has been observed, the presence of these sex chromosomes directly influences the transcriptional landscape of individual cells, leading to sex-specific cellular characteristics. For example, in birds, studies have shown that male (ZZ) and female (ZW) cells exhibit distinct gene expression profiles even when exposed to ...

Java sparrow is a popular cagebird, and has been introduced in a large number of other countries. Both Padda species are threatened by trapping for the cage bird trade. Many taxonomists now place this genus in Lonchura with the mannikins and munias.

Various visual signals act in combination to attract a mate and female choice will shift toward several particularly exaggerated traits. [ 20 ]

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.
