Abstract

Two studies were conducted to investigate the relation between the male cowbird's (Molothrus ater ater) development of a song repertoire and the female cowbird's assessment of song potency. Male development was assayed by vocal copying and female assessment by copulatory responsiveness to song playback. The results demonstrate that males do not copy most often the particular songs that females respond to most often. Whereas rank orderings of potency were highly correlated across two independent samples of playback females, male and female rank orderings were not significantly correlated. The data highlight the potential significance of social interactions between and across the sexes for repertoire development.

摘要

进行了两项研究，以调查雄性褐头牛鹂（Molothrus ater ater）歌曲 repertoire 的发展与雌性褐头牛鹂对歌曲效力的评估之间的关系。通过声音模仿来测定雄性的发展，通过对歌曲回放的交配反应来测定雌性的评估。结果表明，雄性最常模仿的歌曲并非雌性反应最强烈的那些特定歌曲。虽然在两个独立的回放雌性样本中，效力的排名顺序高度相关，但雄性和雌性的排名顺序并无显著相关性。这些数据凸显了性别之间和性别内部的社会互动对 repertoire 发展的潜在重要性。
