鸟类第二性征的进化，如大型歌曲曲目和明亮的羽毛颜色，已经被解释为性选择。在雄性红腹姬鹬中，歌声的复杂性与身体状况和羽毛颜色等表型品质相关。在这里，我们实验表明，女性更喜欢男性与较大的歌曲数字曲目和更多才多艺的歌曲时，一个男性之间的选择较小的曲目和多才多艺的歌曲和另一个男性与较大的曲目和更多才多艺的歌曲。其他雄性特征，如羽毛颜色，在两个雄性中相似。在鸟舍里，雌鸟开始用更复杂的歌声与雄鸟一起筑巢。我们讨论了潜在的好处，女性选择男性复杂的歌曲。
The evolution of secondary sexual male characteristics such as large song repertoires and bright plumage colour in birds, has been explained by sexual selection. In male pied flycatchers, Ficedula hypoleuca, song complexity correlates with phenotypic qualities like body condition and plumage colour. Here we show experimentally that females prefer males with larger song figure repertoires and more versatile song when given the choice between a male with a smaller repertoire and less versatile song and another male with a larger repertoire and more versatile song. Other male characteristics, like plumage colour, were similar in the two males. In the aviaries, the females started nest building with the male with the more complex song. We discuss potential benefits to females of choosing males with complex song.
