据一项研究显示,佛罗里达州的野生海豚使用独特的口哨声和名字一样, Wild dolphins in Florida use unique signature whistles like names, especially when alone or in murky water, a study shows.

长期对佛罗里达州萨拉索塔的海豚进行研究发现,野生海豚使用独特的口哨方式来识别自己,尤其是在孤立或低可见度条件下. A long-running study of bottlenose dolphins in Sarasota, Florida, has found that wild dolphins use unique signature whistles—similar to names—to identify themselves, especially in isolation or low-visibility conditions. 研究人员记录了300多个人的近1000次口哨, 通过在健康检查期间连接的水声机来确认约85%的口笛是标志性的口哨. Researchers recorded nearly 1,000 whistle sessions from over 300 individuals using hydrophones attached during health checks, confirming that about 85% of whistles in isolation are signature whistles. 鱼在与小牛交谈时会修改自己的口哨,这种行为类似于人类的"母声",并且可能模仿其他动物的口笛来开始接触. Dolphins modify their whistles when speaking to calves, a behavior akin to human "motherese," and may copy others’ whistles to initiate contact. 雌性在长时间内保持稳定的口哨声,而雄性可能会改变它们的口笛声,尤其是在长期男性结合期间. Females tend to keep stable whistles over time, while males may change theirs, especially during long-term male bonds. 研究还发现多只海豚共用非签名的哨声, 表明它们有复杂的社交交流. The study also revealed shared non-signature whistles used by multiple dolphins, suggesting complex social communication. 这项研究自1970年以来一直在进行, 仍然是世界上对野生鱼最长的研究. The research, ongoing since 1970, remains the world’s longest study of wild cetaceans.
