Acoustic data of calls of Manx shearwater on Lundy Island

Vocalizations are widely used to signal behavioural intention in animal communication, but may also carry additional information encoded in the signal, in particular, vocalisations may carry acoustic signatures unique to the calling individual. Manx shearwater (Puffinus puffinus) are nocturnal seabirds that breed in dense colonies, where they must recognize and locate mates among thousands of conspecifics calling in the dark. There is evidence for individual vocal signatures in two shearwater species, but quantitative data on the vocalisations of Manx shearwater are lacking. We recorded calls of 13 Manx shearwaters on Lundy Island, UK, by eliciting vocal responses to playback of conspecific calls. We measured several spectral and temporal parameters of the calls, applied linear discriminate analysis with leave-one-out cross-validation, and have confirmed the individual vocal signatures. We then calculated among-individual repeatability of 34 features describing the vocalization to deter..., , ,

发声行为（vocalizations）在动物通讯中广泛用于传递行为意图，同时还可在信号中编码额外信息，具体而言，发声可携带发出个体独有的声学特征标识（acoustic signatures）。曼克斯剪水鹱（Manx shearwater，学名*Puffinus puffinus*）是夜行性海鸟，营高密度群落繁殖，它们需要在黑暗中成千上万只同种个体的鸣叫声中识别并定位配偶。已有研究在两种剪水鹱物种中发现了个体专属发声标识，但目前仍缺乏曼克斯剪水鹱发声行为的量化数据。本研究于英国伦迪岛（Lundy Island）录制了13只曼克斯剪水鹱的鸣叫声，通过播放同种鸣叫声诱导其产生发声应答。研究人员测量了鸣叫声的多项频谱与时域参数，采用留一交叉验证法（leave-one-out cross-validation）开展线性判别分析（Linear Discriminant Analysis），证实了曼克斯剪水鹱存在个体专属发声标识。随后本研究针对34项描述发声特征的参数计算了个体间重复性，以探究……（原文此处内容未完整呈现）
