虽然在其他种类的吼猴中也观察到了杀鼠剂，并推断为Alouatta pigra，但在此物种中观察到的杀鼠剂病例以前没有记录。在这里，我们描述了一个2周大的婴儿被杀害的居民男性的一个小社会群体在南部伯利兹。2003年1月开始的一项密集的观察性研究目睹了这一屠杀。据了解，这名男子在该群体中居住了至少4个月，但不知道他是否是婴儿的父亲。文献对杀婴提出了三种主要解释：两种适应性假设（性选择和资源竞争）和一种非适应性假设（社会病理学）。像这样的个别杀害儿童案件对于比较目的来说很重要，但如果单独审查，就很难根据既定的理论框架来解释。这里提供的数据显示了与性选择和资源竞争假设的一些一致性，但缺乏关键信息（即，（关于亲子关系）使我们无法得出确切的结论。Am.

Although infanticide has been witnessed in other species of howler monkey, and has been inferred for Alouatta pigra, an observed case of infanticide has not previously been recorded for this species. Here we describe the killing of a 2‐week‐old infant by the resident male of a small social group in southern Belize. The infanticide was witnessed as part of an intensive observational study that began in January 2003. The male was known to have resided in the group for at least 4 months, but it is not known whether he was the father of the infant. The literature proposes three main explanations for infanticide: two adaptive hypotheses (sexual selection and resource competition), and one nonadaptive hypothesis (social pathology). Individual cases of infanticide such as this one are important for comparative purposes, but when examined on their own they are difficult to interpret in relation to established theoretical frameworks. The data presented here show some consistency with the sexual‐selection and resource‐competition hypotheses, but the lack of critical information (i.e., as to paternity) makes it impossible to draw firm conclusions.
