对哥斯达黎加圣罗莎国家公园的两组白面卷尾猴（Cebus capucinus）进行的一项长期研究提供了证据，表明与宿务市其他实地研究报告相比，脊椎动物的捕食程度异常高。描述了不同猎物类型的狩猎技术，并解决了有关灵长类脊椎动物捕食的几个问题。为什么个体之间和群体之间的捕食率存在差异？为什么雄性比雌性捕猎更多？先前解释旧大陆灵长类动物狩猎的假设适用于这个新热带地区的例子。最后，我认为成功的脊椎动物捕食很容易出现在像塞布斯这样的物种中，这些物种的特点是机会主义的觅食模式、操纵和认知技能以及发达的定位和制服无脊椎动物猎物的技术。
A long-term study of two groups of white-faced capuchins (Cebus capucinus) in Santa Rosa National Park in Costa Rica provides evidence of unusually high levels of vertebrate predation compared to those reported in other field studies of Cebus. The hunting techniques for different prey types are described, and several questions concerning vertebrate predation in primates are addressed. Why is there variation between individuals and between groups in the rate of predation? Why do males hunt more than females? Previous hypotheses to explain hunting in Old World primates are applied to this Neotropical example. Finally, I argue that successful vertebrate predation can readily arise in species like Cebus, which are characterized by opportunistic foraging patterns, manipulative and cognitive skills and well-developed techniques for locating and subduing invertebrate prey.
