鸟类Poecile属的Chick-a-Dee叫声是一个结构复杂的发声系统，因为它有一套简单的规则来控制叫声的音符如何排序，每种音符类型的可变数量串连在一起可以产生非常多的独特叫声。虽然假设不同音符的叫声可能传达不同的信息，但没有实验证据支持这一假设。此前发表的研究表明，鸟群成员在迁入或离开喂食点时会发出鸡叫声。在这里，我们测试了卡罗莱纳州的雏鸟对不同音符组成的Chick-a-Dee呼叫回放的反应。在一种新的食物来源的背景下，在实地进行了回放。我们的试验数据表明，鸟类在第一次接触一种新的种子林时发出了相对较大数量的C音符的鸡叫声。在目前的研究中，我们发现，在回放包含C音符的Chick-a-Dee呼叫的回放过程中，与不包含C音符的Chick-a-Dee呼叫或控制回放相比，小山雀飞入靠近回放扬声器的位置并随后从种子台上取下种子的频率更高。山雀对回放的声音反应也因回放的特定声音信号而有所不同。这些结果表明，接收者对包含不同音符类型组成的Chick-a-Dee呼叫的反应是不同的，并代表了将音符组成的变化和这些呼叫中的顺序与可能的含义联系起来的第一步。(C)2002年动物行为研究协会。爱思唯尔科学有限公司出版。版权所有。
The chick-a-dee call of the avian genus Poecile is a structurally complex vocal system because it possesses a set of simple rules that governs how the notes of the call are ordered, and variable numbers of each of the note types strung together can generate an extraordinary number of unique calls. Whereas it has been hypothesized that chick-a-dee calls with different notes may convey different information, no experimental evidence has been offered in support of the hypothesis. Previously published studies suggested that flock members use chick-a-dee calls in the context of moving to or from a feeding site. Here, we tested Carolina chickadees' responses to playbacks of chick-a-dee calls that differed in note composition. Playbacks were conducted in the field in the context of a novel food source. Our pilot data had indicated that chick-a-dee calls with relatively large numbers of 'C' notes were given by birds on their first contact with a novel seed stand. In the present study, we found that chickadees flew in close to the playback speaker and subsequently took seed from a seed stand more often during playbacks of chick-a-dee calls containing C notes than chick-a-dee calls not containing C notes or than control playbacks. Vocal responses of chickadees to the playbacks also differed in relation to the particular vocal signal being played back. These results indicate that receivers respond differently to chick-a-dee calls containing different compositions of note types and represent a first step to link variation in note composition and ordering in these calls to possible meanings.
