Crop-raiding by wildlife species often involves collective group movement and animal decision-making in this context is an important area of investigation as the risks and rewards associated with crop-raiding are greater than those that are likely to occur in wild food foraging situations. Yet, the form of consensus decision-making involved in wildlife crop-raiding has not been evaluated. In the current study, we assessed the decision-making process exhibited by rhesus macaques, a generalist primate species, in the context of crop-raiding. We predicted that rhesus macaques would display unshared consensus decision-making during the higher risk-entailed crop-raiding collective movements. We followed two groups of rhesus macaques and collected data on their movement and foraging behavior during crop-raiding events. The results from our study showed that collective movements in the context of crop-raiding were largely led by single individuals. However, individuals of all age-sex categories successfully led crop-raiding collective movements. Although adult individuals joined adult-initiated raid movements most often, they also joined raids initiated by other age classes. Contrary to our predictions, in crop-raiding contexts, rhesus macaques demonstrated a tendency towards equally shared decision-making for group movements.

野生动物掠夺作物通常涉及集体群体运动，在这种情况下，动物决策是一个重要的调查领域，因为与掠夺作物相关的风险和回报大于在野生食物觅食情况下可能发生的风险和回报。然而，尚未评估涉及野生动物作物袭击的共识决策形式。在目前的研究中，我们评估了恒河猴（一种多面手的灵长类动物）在掠夺作物的情况下所表现出的决策过程。我们预测，恒河猴在高风险的农作物掠夺集体运动中会表现出不共享的共识决策。我们跟踪了两组恒河猴，并收集了它们在掠夺作物期间的运动和觅食行为的数​​据。我们的研究结果表明，在掠夺作物的背景下的集体运动主要由个人领导。然而，所有年龄性别类别的个人都成功地领导了抢夺作物的集体运动。尽管成年人最常参加由成人发起的突袭运动，但他们也参加了由其他年龄层发起的突袭。与我们的预测相反，在掠夺作物的情况下，恒河猴表现出对群体运动进行平等共享决策的趋势。
