橙色头部的圆锥体使用各自不同的联系呼叫(CHIE)来调解社会互动。众所周知，在语音交流过程中，人们会模仿对方的联系电话。奶酪通常是单数给出的，但也会出现在双层奶酪中，称为双重奶酪。我们使用交互回放来评估双重语气在模仿语境中的作用。通过使用不同程度相似程度不同的刺激，我们发现野生捕获的圆锥体在鸟舍中短期保存时，比起第一个乳突，更多地模仿双乳突中的第二个乳突。这表明，在调解交流方面更相关的信息包含在第二个Chee中，第一个Chee起到了某种替代功能。双人舞不会增加互动的整体强度，也不会提高模仿的整体准确性。然而，在CHEE交换过程中，双重CHIE可能起到信号和引导变化的作用。
Orange-fronted conures use individually distinctive contact calls (chees) to mediate social interactions. During vocal exchanges, individuals are known to imitate each other's contact calls. Chees are most often given singularly, but also occur in doublets, known as double chees. We used interactive playback to assess the function of double chees in imitative contexts. By using stimuli with varying levels of similarity between the chees within a double chee, we found that wild-caught conures held for short periods in an aviary imitate the second chee of the double chee more than the first chee. This suggests that the more relevant information in mediating the exchange is contained in the second chee, and the first serves some alternative function. Double chees do not increase the overall intensity of an interaction, nor do they improve the overall accuracy of imitation. However, double chees may serve a role in signaling and directing changes during chee exchanges.
