野外观察和声学分析表明，不同捕食者的叫声结构不同。在这项研究中，我们测试了接收器是否做出适当的反应，然后在没有捕食者的情况下听到呼叫。虽然唯一的方法为surcites逃离掠食者是撤退到避难所，反应回放可以分为不同的类别。受试者的反应不同的报警电话，在响应空中或陆地捕食者和招聘电话发出的蛇和存款在地面上。Suricates也表现出相当不同的反应，腰部，中，高紧急空中呼叫。在地面和招募电话的不同紧急程度的反应差异不太明显。因此，Suricate接收器从它们叫声的声学结构中获得关于捕食者类型和紧急程度的信息。
Field observations and acoustic analyses have shown that suricate (Suricata suricatta) alarm calls vary in their acoustic structure depending on predator type. In this study, we tested whether receivers respond appropriately,then hearing a call in the absence of a predator. Although the only way for suricates to escape from predators is to retreat to boltholes, responses to playbacks could be divided into distinct categories. The subjects responded differently to alarm calls given in response to aerial or terrestrial predators and to recruitment calls emitted in response to snakes and deposits on the ground. Suricates also showed rather distinct responses to loin, medium and high urgency aerial calls. Differences in the responses were less obvious for different levels of urgency in the terrestrial and recruitment calls. Suricate receivers thus gain information about both the predator type and level of urgency from the acoustic structures of their calls.
