AbstractWe report on long-range duet interactions among twelve wild groups of lar gibbons (Hylobates lar) in Thailand. Statistical analysis demonstrates that groups were more likely to respond with an answering duet to a duet sung by a neighbouring group than to one sung by a non-neighbouring group in the population. A distinctive pattern of response among neighbours was to wait until a neighbouring group had finished its duet before immediately answering with a duet, resulting in avoidance of overlap between the two duets. Non-neighbours did not exhibit this pattern. The effect is shown to be due solely to neighbour status and not to the degree of mutual audibility of the duets. There was no evidence that, when duets overlapped, the first group to sing modified the length of its duet in response to the second duet, whether given by a neighbour or by a non-neighbour. In general, among those groups which responded to one another's duets, there were no identifiable leaders and followers: the order of duetting groups was random. We discuss why neighbours interact more by duet than do non-neighbours, and consider what may be the functions of avoiding overlap of duets.

Vocal Interactions

What information animals derive from eavesdropping on interactions between conspecifics, and whether they assign value to it, is difficult to assess because overt behavioral reactions are often lacking. An inside perspective of how observers perceive and process such interactions is thus paramount. Here, we investigate what happens in the mind of marmoset monkeys when they hear playbacks of positive or negative third-party vocal interactions, by combining thermography to assess physiological reactions and behavioral preference measures. The physiological reactions show that playbacks were perceived and processed holistically as interactions rather than as the sum of the separate elements. Subsequently, the animals preferred those individuals who had been simulated to engage in positive, cooperative vocal interactions during the playbacks. By using thermography to disentangle the mechanics of marmoset sociality, we thus find that marmosets eavesdrop on and socially evaluate vocal exchanges and use this information to distinguish between cooperative and noncooperative conspecifics.

Vocal Interactions

Vocal interactions between humans and non-human animals are pervasive, but studies are often limited to communication within species. Here, we conducted a pilot exploration of vocal interactions between visitors to the San Diego Zoo Safari Park and Sampson, an 18-year-old male Hyacinth Macaw residing near the entrance. Over the course of one hour, 82 vocal and behavioral events were recorded, and various relationships between human and bird behavior were noted. Analyses of this type, applied to large datasets with assistance from artificial intelligence, could be used to better understand the impacts, positive or negative, of human visitors on animals in managed care.
