| 英文摘要 | Odontocetes display a wide range of surface behaviors, including aerial and percussive behaviors. However, only a handful of studies have quantitatively investigated the context and function of surface behavioral events in odontocetes. Here, the display of breaching, side breaching, and tail-slapping by Indo-Pacific humpback dolphins (Sousa chinensis) was observed during surveys conducted in three locations of the northern South China Sea. The analysis of 380 encounters revealed that, while breaching was not associated with particular contexts, side breaching was mostly displayed during foraging, probably to gather prey during feeding events, and could therefore be further used to indicate foraging activity. Tail-slapping was displayed significantly more during spring than in other seasons, during socializing and traveling than during other activities, and in larger than in smaller groups. This behavior was mostly displayed by old individuals in a variety of contexts, indicating a potential range of functions including attracting attention, communicating information, expressing an emotional state, or gathering prey together. Unexpectedly, tail slaps were significantly less frequent when the research boat actively followed dolphins, showing that the link between this behavior and human disturbances is not clear. More research is needed to investigate details regarding the display of tail slaps in order to be able to reliably use it as a cue to monitor during surveys that indicates that dolphins are being impacted due to disturbance from boats. Furthermore, differences in the display of surface behavioral events were observed among locations, which may be attributed to differences in foraging and/or communication strategies among different populations. The results obtained here will be useful for behavioral monitoring during field surveys.Significance statementEven though aerial and percussive behaviors are commonly observed in odontocetes, research conducted on these behaviors is scarce and their function(s) are not well understood yet. These functions may vary depending on the species and even on the population. Understanding the context and function of these behaviors is of significant importance for better monitoring animal behavior in the wild (e.g., categorizing the animals' behavioral state, noticing signs of disturbance). The present study is the first to investigate aerial and percussive behaviors (i.e., breaching, side breaching, and tail slapping) in wild Indo-Pacific humpback dolphins. Dolphins exhibited differences in the frequency at which they display these behaviors depending on the population and the behavioral state of the group. These results inform on the potential communication/foraging strategies differences among populations and provide cues to better monitor dolphins' behavior in the field. |
