Food associated calls have been described in several species of primates. These vocalizations serve to attract other group members to the food source but their informational content, adaptive significance, and consequences for foraging animals are poorly understood. The ecological factors and evolutionary forces that led to the important role of intra-group exchange and cooperative foraging activities in human hunter-gatherer societies have been amply discussed, but few data from other primate species exist to provide a comparative framework. Understanding the adaptive significance of apparently cooperative foraging behaviors in non-human primates and other vertebrates will help to address these questions. This proposal is aimed at understanding the informational content and adaptive significance of food associated calls of tufted capuchin monkeys. The vocal repertoire of this species, in terms of acoustic structure and socioecological context of vocalizations, will be obtained from tape recordings of the animals' vocalizations in Iguazu National Park, Argentina. Field playback experiments will be used to understand the informational content of these vocalizations. Food discovery experiments using feeding platforms will be used to evaluate how the food-associated calls are affected by different socioecological contexts, and to explore the possibility of deceptive use of these signals by capuchins. Field experiments with models of predators also will be performed to test the hypothesis that food associated calls are given to reduce predation risk by attracting other groups members to the food source. The predictions of eight different hypotheses on the adaptive significance of these calls will be tested using the tape-recordings of vocalizations and the results of field experiments. The results obtained from this project will help to understand the origin of apparently altruistic behaviors that play an important role in the foraging activities of humans and non-human primates.

在几种灵长类动物中描述了食物相关的呼唤。 这些发声有助于吸引其他小组成员进入食物来源，但是他们的信息内容，适应性意义以及觅食动物的后果知之甚少。 已经充分讨论了导致群体内交换和合作觅食活动的重要作用的生态因素和进化力量，但已经充分讨论了人类狩猎者社会，但是很少有其他灵长类动物的数据能够提供比较框架。 了解非人类灵长类动物和其他脊椎动物中显然合作觅食行为的适应性意义将有助于解决这些问题。 该建议旨在了解簇绒尾猴猴子相关的呼叫的信息内容和适应性意义。 就声音结构和社会生态环境而言，该物种的声带曲目将从阿根廷伊瓜苏国家公园的动物发声录音中获得。 现场播放实验将用于了解这些发声的信息内容。 使用喂养平台的食物发现实验将用于评估与食物相关的呼叫如何受到不同社会生态环境的影响，并探索卷尾猴欺骗性使用这些信号的可能性。 还将对捕食者模型进行现场实验，以检验以下假设，即通过吸引其他群体成员进入食物来源，给予食物相关的呼叫以降低捕食风险。 对这些调用的自适应意义的八个不同假设的预测将使用磁带录制和田间实验的结果进行测试。 从该项目获得的结果将有助于理解在人类和非人类灵长类动物的觅食活动中起着重要作用的显然无私行为的起源。
