Ambush predators rely on stealth to successfully secure prey. Mobbing is a rarely observed anti-predation strategy used by group-living prey species whereby several individuals distract or harass a predator until it either ends the pursuit or leaves the area. Herein, we present three unique cases of white-lipped peccaries (Tayassu pecari) mobbing jaguars (Panthera onca) in the wild. White-lipped peccaries and jaguars co-occur within the study area, a large-scale ecotourism and working cattle ranch in the Brazilian Pantanal. Two cases of mobbing were recorded by video camera trap during routine surveys, and a third case was directly observed by one of the authors during telemetry triangulation of a GPS-collared individual jaguar. Our observations provide direct empirical evidence of antagonistic behavioral interactions between jaguars and white-lipped peccaries that have previously been limited to anecdotes within academic literature. We discuss the implications of this behavioral interaction for the proximate and ultimate fitness of both predator and prey.

捕食者与猎物之间的对抗性相互作用：白唇野猪（Tayassu pecari）围捕美洲虎（Panthera onca）

伏击捕食者依靠隐身成功地捕获了猎物。围攻是一种鲜为人知的反捕食策略，被一群活着的猎物使用，一些人分散或骚扰捕食者，直到其结束追捕或离开该区域。在此，我们介绍了三种独特的案例：白唇野猪（Tayassu pecari）围攻美洲虎（Panthera onca）） 在野外。研究区域内出现了白唇野兽和美洲虎，巴西潘塔纳尔湿地的大规模生态旅游和劳作牛牧场。例行调查期间，摄像机陷阱记录了两起围攻事件，而其中一位作者在对GPS领的美洲虎进行遥测三角测量时直接观察到了第三起事件。我们的观察结果提供了直接的经验证据，证明美洲虎和白唇野猪之间的拮抗行为相互作用以前仅限于学术文献中的轶事。我们讨论了这种行为交互对捕食者和被捕食者的接近和最终适应的影响。
