Animals are often covered with stripy or dotty patterns on their body surface, which can help them to hide or to signal. Estrildid finches are especially rich in species with plumage patterns but their geometric features show great variations. Our comparative study revealed that conspicuous plumage patterns are possessed by species with an elaborate courtship dance, suggesting that plumage patterns in estrildid finches work as sexual signals in both sexes.
