Data and code from: Female and male plumage colour is linked to parental quality, pairing and extra-pair mating in a tropical passerine

Sexual selection has been proposed to drive the evolution of elaborate phenotypic traits in males, which often confer success in competition or mating. However, in many species both males and females display such traits, although studies investigating selection acting in both sexes are scarce. In this study, we investigated whether plumage ornamentation is sexually selected in female and male lovely fairy-wrens Malurus amabilis, a cooperatively breeding songbird. We found that female and male plumage colour was correlated with parental quality but not with individual quality and survival. We also found evidence of positive assortative mating based on plumage colour. Microsatellite analyses of paternity indicated that the lovely fairy-wren has high levels of extra-pair paternity, with 53% of offspring (in 58% of broods, of 57% of females) resulting from extra-pair mating. Female and male plumage colour did not predict reproductive success or the proportion of extra-pair offspring in thei..., Detailed methods describing the dataset collection can be found in Leitão, Hall and Mulder \"Female and male plumage colour is linked to parental quality, pairing and extra-pair mating in a tropical passerine\".
