Cannibalism has been observed in a variety of animal taxa; however, it is relatively uncommon in primates. Thus, we rely heavily on case reports of this behavior to advance our understanding of the contexts under which it occurs. Here, we report the first observation of cannibalism in a group of wild white‐faced capuchin monkeys (Cebus imitator). The subject was a dead infant, estimated to be 10 days old, and the probable victim of infanticide. Consumption of the corpse was initiated by a 2‐year‐old male (second cousin of the infant), though it was eventually taken over and monopolized by the group's alpha female (grandaunt of the infant). Although most group members expressed interest in the corpse (sniffing, touching, and threatening it), no others made an attempt to consume it. Given that this is the only observation of cannibalism recorded in over 37 years of study on this population, we consider it to be a rare behavior in this species. This detailed record contributes new data, which, when combined with other reports within and across species and contexts, enables the evaluation of adaptive explanations of cannibalism.

野生白脸卷尾猴的婴儿同类相食现象



在多种动物类群中都观察到同类相食的现象。然而,这在灵长类动物中相对罕见。因此,我们在很大程度上依赖这种行为的案例报告来加深我们对其发生背景的理解。在这里,我们首次观察到一群野生白脸卷尾猴( Cebus imitator )同类相食的现象。对象是一名死婴,估计出生 10 天,可能是杀婴事件的受害者。尸体的食用是由一名 2 岁男性(婴儿的远房表弟)发起的,但最终被该群体的阿尔法女性(婴儿的祖母)接管并垄断。尽管大多数小组成员都对尸体表示了兴趣(嗅、触摸和威胁它),但没有其他人试图吃掉它。鉴于这是对该种群超过 37 年的研究中唯一记录到的同类相食现象,我们认为这是该物种的罕见行为。这份详细的记录提供了新的数据,当与物种内部和跨物种和环境的其他报告相结合时,可以评估对同类相食的适应性解释。
