短吻海豚（Tursiops truncatus）是少数几种能够通过声音学习发明新的声学信号并复制同种哨声的动物之一。此外，接收器可以从口哨的发明部分提取身份信息。在人工饲养的海豚中，当它们与群体中的其他成员分开时，它们会发出这种标志性的哨声。然而，人们对它们在海上的使用方式知之甚少。如果信号哨是传递身份信息的主要工具，那么海豚应该在群体或个体加入的情况下交换这些哨声。我们使用被动声定位在焦点船以下观察签名哨子使用在野外。我们发现，刻板的哨声交流主要发生在海豚群在海上相遇和加入时。序列分析验证了连接过程中使用的大多数哨声都是签名哨声。在任何连接中都没有观察到哨声匹配或复制。数据显示，信号哨声交流是问候序列的重要组成部分，这使得海豚在野外遇到同类时能够识别它们。
The bottlenose dolphin, Tursiops truncatus, is one of very few animals that, through vocal learning, can invent novel acoustic signals and copy whistles of conspecifics. Furthermore, receivers can extract identity information from the invented part of whistles. In captivity, dolphins use such signature whistles while separated from the rest of their group. However, little is known about how they use them at sea. If signature whistles are the main vehicle to transmit identity information, then dolphins should exchange these whistles in contexts where groups or individuals join. We used passive acoustic localization during focal boat follows to observe signature whistle use in the wild. We found that stereotypic whistle exchanges occurred primarily when groups of dolphins met and joined at sea. A sequence analysis verified that most of the whistles used during joins were signature whistles. Whistle matching or copying was not observed in any of the joins. The data show that signature whistle exchanges are a significant part of a greeting sequence that allows dolphins to identify conspecifics when encountering them in the wild.
