They can be classified as the family '''Estrildidae''' (weaver-finch), or as a sub-group within the family [[Passeridae]], which also includes the [[true sparrow]]s. They live in [[Flock (birds)|flocks]] 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 pattern. All the estrildids build large domed nests and lay 5–10 white eggs. Many species build roost nests. Some of the fire-finches and pytilias are hosts to the brood-parasitic [[indigobird]]s and whydahs respectively. Most are sensitive to cold and require a warm, usually tropical, habitat, although a few have adapted to the cooler climates of southern [[Australia]]. [[Category:Passeri]] {{biology-stub}}
