Predation risk has played an important role in primate behavioral evolution, yet natural primate-predator interactions are rarely observed. We describe the consumption and probable predation of an adult bald-faced saki monkey (Pithecia rylandsi) by a black-and-white hawk-eagle (Spizaetus melanoleucus) at the Los Amigos Biological Station in lowland Amazonian Peru. To our knowledge, this is the first published case of a black-and-white hawk-eagle consuming any primate species. We contend that while most reported observations of successful and attempted predation by raptors involves the largest and most notorious species (i.e. the harpy eagle), smaller and lesser known species like S. melanoleucus should be considered more seriously as a predator of neotropical primates. We discuss the predation event in the context of understanding what other neotropical primates might be vulnerable to S. melanoleucus predation given its body size and hunting tactic.
捕食风险在灵长类动物行为进化中发挥了重要作用，但自然状态下灵长类动物与捕食者的互动却很少被观察到。我们描述了在秘鲁低地亚马逊地区的洛斯阿米戈斯生物站，一只成年白面僧面猴（Pithecia rylandsi）被一只黑白鹰雕（Spizaetus melanoleucus）捕食的情况及可能的捕食过程。据我们所知，这是首次有关于黑白鹰雕捕食任何灵长类物种的公开报道。我们认为，虽然大多数关于猛禽成功捕食和尝试捕食的报道都涉及体型最大、最臭名昭著的物种（如角雕），但像黑白鹰雕这样体型较小且鲜为人知的物种，作为新热带界灵长类动物的捕食者，也应得到更认真的对待。我们结合黑白鹰雕的体型和捕猎策略，讨论这起捕食事件，以了解其他新热带界灵长类动物可能在多大程度上易受其捕食。
