The estrildid finches
are small passerine birds
of the Old World
tropics and Australasia
They are gregarious and often colonial seed-eaters with short, thick, but pointed bills. They are all similar in structure and habits, but vary widely in plumage colours and patterns.
All the estrildids build large, domed nests and lay 5–10 white eggs
