本文报道了在均匀生境中对雄性姬小蜂配对成功率进行的两年研究结果。进行了一项障碍实验，其中某些翅膀和尾巴的羽毛被删除从随机选择的男性。残疾的男性配对成功率降低，体重减轻，唱歌的频率也低于对照组。雄性配对的成功率与羽毛的颜色、体型和以前的繁殖经验呈正相关。早期对同一物种的研究未能发现配对成功和雄性特征之间的任何关系，可能是因为栖息地的异质性和巢址质量的变化。雌性选择雄性特征的进化基础进行了讨论。有报道称，具有吸引力特征（例如黑色羽毛）的雄性提供了高质量的父母照顾。然而，事实上，男性配对成功与男性的显着性，很难区分主动和被动的女性选择。
The paper reports the results of a 2-year study of pairing success of male pied flycatchers in a homogeneous habitat. A handicapping experiment was carried out in which certain wing and tail feathers were removed from randomly selected males. Handicapped males had reduced pairing success, they lost weight, and they sang less frequently than control males. Male pairing success was positively correlated with the darkness of the plumage, body-size, and previous breeding experience. Earlier studies on the same species have failed to detect any relationships between pairing success and male characteristics, possibly because of habitat heterogeneity and variation in nest site quality. The evolutionary basis for female choice of male characteristics is discussed. There are reports that males with attractive traits (e.g. black plumage) provide a high quality of parental care. However, the fact that male pairing success was related to male conspicuousness makes it difficult to discriminate between active and passive female choice.
