许多经典的性选择特征的例子是由雌性做出明智的配偶选择造成的。雄性以牺牲雌性选择为代价来增加自己繁殖成功率的行为可能会破坏这种交配系统。我们记录了一个明显罕见的例子，这种行为涉及作弊的一个facultiplex-cooperatively显示侏儒物种（白皱侏儒，Corapipo altera）。作弊事件发生后，我们观察到雄性在现场展示的行为和活动发生了巨大变化，并且没有随后的雌性访问。我们推测，偶然的合作行为的罕见可能部分是由于在这样的系统中固有的作弊风险。与该文章相关的数字视频图像可在http://www.momo-p.com/showdetail-e.php?上获得movieid=momo190323ca01a.
Many classic examples of sexually selected traits result from females making informed mate choices. Behaviors by males that increase their own reproductive success at the expense of female choice can undermine such mating systems. We documented an apparently rare example of such a behavior involving cheating in a facultatively cooperatively-displaying manakin species (White-ruffed manakin, Corapipo altera). After the cheating event, we observed a dramatic change in the behavior and activity of males displaying at the site and no subsequent female visits. We hypothesize that the infrequency of facultative cooperative behavior may in part result from cheating risks inherent in such systems.
