The black-faced black spider monkey, Ateles paniscus chamek, was studied at Cocha Cashu, Manu National Park, Peru, from June to August 1982. The density of independently locomoting individuals was found to be 31/km, and the average party size was 3.15. Data on age and sex compositions of parties, activity patterns, and diet composition are presented. The spider monkeys spend approximately 30% of observed time feeding, 44% resting, and 25% moving. They ate 80% fruit and 17% new leaves. Spider monkeys appear to be important seed dispersers. The best dispersal observed was for fruits with few, relatively large seeds. A rough day-range of 2,400 m was estimated from measured travel times and distances. The social system of Ateles is discussed.
1982年6月至8月，在秘鲁马努国家公园的科查卡舒对黑脸黑蜘蛛猴（Ateles paniscus chamek）进行了研究。发现独立活动个体的密度为每平方公里31只，平均群聚规模为3.15只。文中呈现了关于群聚的年龄和性别组成、活动模式以及饮食组成的数据。蜘蛛猴在观察时间中约30%用于进食，44%用于休息，25%用于移动。它们80%的食物为水果，17%为新叶。蜘蛛猴似乎是重要的种子传播者。观察到的最佳传播情况是针对种子数量少、相对较大的水果。根据测量的行进时间和距离估算出大致的日活动范围为2400米。文中还讨论了蛛猴属的社会系统。
