摘要我们研究了歌长和歌唱速率在刺激雌性白喉麻雀Zonotrichia albiollis中的重要性。1988年11月，10只雌性和1只雄性白喉麻雀在秋季迁徙中被捕获。为了增强性感受性的表达，在雌性动物体内植入了17-β-雌二醇硅橡胶颗粒。利用不唱歌的雄性的视觉刺激来进一步增强雌性的性接受能力的表达，我们发现雌性以交配展示的形式对典型的雄性白喉麻雀的五个音符的歌声比两个音符的歌声有更大的反应。每个版本以每分钟四首歌曲的速度播放。1990年5月，鸟儿被捕获并像以前一样被对待，只是两个音符的歌曲以每分钟10首歌的速度播放，五个音符的歌曲以每分钟四首歌的速度播放。因此，每个女性每分钟能听到20个音符。在第二个实验中，女性对两个音符和五个音符的歌曲回放没有表现出统计上的差异。我们将第二个实验的结果解释为，歌唱速度和歌声长度在刺激雌性白喉麻雀方面是重要的，因为增加两个音符的歌声的速度使反应达到我们对以较慢的速度播放的五个音符的反应的水平。我们的结论是，在白喉麻雀中，歌声输出对于雌性刺激是重要的。
SummaryWe investigated the importance of song length and singing rate in stimulating female white-throated sparrows, Zonotrichia albicollis. In November 1988 ten female and one male white-throated sparrow were captured during the fall migration. To enhance the expression of sexual receptivity, the females were implanted with 17-beta-estradiol silastic pellets. Using the visual stimulus of a non-singing male to further enhance the expression of sexual receptivity in the females, we found that females gave a greater response, in the form of copulation displays, to a five-note versus a two-note version of a typical male white-throated sparrow song. Each version was played back at four songs per minute. In May 1990 birds were captured and treated as before, except that the two-note song was played at ten songs per minute and the five-note song at four songs per minute. Therefore, each female heard twenty notes per minute. In the second experiment, the females did not show a statistical difference in response to the two- and five-note song playbacks. We interpret the results of the second experiment as indicating the song rate as well as song length is important in stimulating female white-throated sparrows because increasing the rate of the two-note song brought the response up to the level of response we obtained to the five-note song played at the slower rate. We conclude that in white-throated sparrows, song output is important for female stimulation.
