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.
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表明，与其他关于卷尾猴的野外研究报告相比，脊椎动物被捕食的水平异常高。文中描述了针对不同猎物类型的捕猎技巧，并探讨了几个有关灵长类动物捕食脊椎动物的问题。为什么个体之间以及群体之间的捕食率会存在差异？为什么雄性比雌性捕猎更多？以往用于解释旧世界灵长类动物捕猎行为的假说被应用于这个新热带地区的例子。最后，我认为像卷尾猴这样具有机会主义觅食模式、操作和认知技能以及用于定位和制服无脊椎动物猎物的成熟技巧的物种，很容易出现成功捕食脊椎动物的情况。
