鸣声通常是一种功能明确的交流信号，具有复杂的声学结构，除此之外，鸣禽还会发出各种较短的声音，称为叫声。虽然大量的工作都集中在歌曲中的信息编码上，但人们对叫声的声学结构如何支持交流过程知之甚少。因为雄性和雌性斑胸草雀在它们的大多数互动中都使用叫声，并且在没有视觉接触的情况下回答相同的叫声，我们的目的是确定哪些叫声的声音线索是引起声音反应所必需的。利用合成的斑胸草雀叫声，我们研究了雄性和雌性斑胸草雀对修改版本的远距离叫声的诱发声反应。我们的研究结果表明，斑马雀对雌性鸣叫的声音反应需要完整的和声结构，而雄性鸣叫的频率向下扫描是引起声音反应的必要条件。很可能雌性和雄性的叫声都需要匹配相似的频率带宽来触发同种个体的反应。
Besides their song, which is usually a functionally well-defined communication signal with an elaborate acoustic structure, songbirds also produce a variety of shorter vocalizations named calls. While a considerable amount of work has focused on information coding in songs, little is known about how calls' acoustic structure supports communication processes. Because male and female zebra finches use calls during most of their interactions and answer to conspecific calls without visual contact, we aimed at identifying which calls' acoustic cues are necessary to elicit a vocal response. Using synthetic zebra finch calls, we examined evoked vocal response of male and female zebra finches to modified versions of the distance calls. Our results show that the vocal response of zebra finches to female calls requires the full harmonic structure of the call, whereas the frequency downsweep of male calls is necessary to evoke a vocal response. It is likely that both female and male calls require matching a similar frequency bandwidth to trigger a response in conspecific individuals.
