许多鸟类和哺乳动物的个体在遇到捕食者时会发出反捕食者的叫声。这些电话往往不同的声学结构取决于捕食风险的类型或水平，从而引发适当的逃生反应同种。在动物招募其他个体来围攻捕食者的情况下，这种交流的复杂性也可能是有利的，因为不同的风险有时可能需要不同的围攻反应。我在日本的大山雀中测试了这个想法，Parus major minor，它为两种不同的巢穴捕食者产生了声学上不同的骚扰叫声：“chicka”呼叫丛林乌鸦，乌鸦macrorhynchos，和“jar”呼叫日本鼠蛇，Elaphe climacophora。一项回放实验显示，成年大山雀对不同的骚扰叫声做出了不同的反应：它们在回应“chicka”叫声时会扫描地平线，在回应“jar”叫声时会凝视地面。这两种反应有助于成年人寻找和发现相应的捕食者，因为乌鸦飞到巢穴，蛇从地面接近。这项研究表明，日本大山雀的骚扰电话传递有关捕食者类型的参考信息，并引起适当的捕食者搜索行为的成年人。(C)2012年，动物行为研究协会。由爱思唯尔有限公司出版。保留所有权利。
Individuals of many avian and mammalian species produce antipredator calls when they encounter a predator. These calls often vary in acoustic structure depending on the type or level of predation risk, thereby eliciting the appropriate escape responses in conspecifics. Such complexity in communication may also be advantageous in situations in which animals recruit other individuals to mob predators because different risks may sometimes require different mobbing responses. I tested this idea in Japanese great tits, Parus major minor, which produce acoustically distinct mobbing calls for two different nest predators: 'chicka' calls for jungle crows, Corvus macrorhynchos, and 'jar' calls for Japanese rat snakes, Elaphe climacophora. A playback experiment revealed that adult great tits responded to different mobbing calls with qualitatively different behaviours: they scanned the horizon in response to 'chicka' calls and gazed towards the ground in response to 'jar' calls. These two responses help adults search for and detect the corresponding predators since crows fly to the nest and snakes approach from the ground. This study demonstrates that the mobbing calls of Japanese great tits transmit referential information about predator types and elicit the appropriate predator-searching behaviours in adults.
