在听觉上与雄性隔绝的雌性牛鸟以交配的姿势对雄性牛鸟的歌声做出反应。在与世隔绝的环境中养育的雄鸟的歌声比正常饲养的雄鸟的歌声更能有效地激发出它们的姿势。雌性对其他物种的歌声没有反应。这些结果表明了该寄生物种的一种鉴定机制。
Female cowbirds raised in auditory isolated from males responded to the songs of male cowbirds with copulatory postures. The songs of males reared in isolated were more effective in eliciting the posture than the songs of normally reared males. The females did not respond to the songs of other species. These results indicate one mechanism of species identification for this parasitic species.
