从1979年8月到1982年5月，在坦桑尼亚西部的Mahale记录了54次野生黑猩猩的捕食行为。黑猩猩最经常在两个季节狩猎，在5月，从8月到12月。长期粪便分析表明，捕食频率显着高于在旱季比雨季。捕食的季节性可能是各种生态因素综合作用的结果，其中至少有一个是被捕食物种的出生季节。大多数的猎物是青少年蓝小羚羊，羚羊，野猪，红疣猴和红尾猴。性别差异是公认的猎物选择和狩猎方法。Mahale和Combe黑猩猩之间捕食行为的明显地方差异（在Mahale，女性狩猎更频繁，蓝色小羚羊是最常见的猎物）可以通过观察方法或区系多样性和密度的差异来理解。掠夺行为的其他方面也有报道。
Fifty-four episodes of predatory behavior of wild chimpanzees were recorded in Mahale, western Tanzania, from August 1979 to May 1982. The chimpanzees most frequently hunt in two seasons, during May, and from August to December. Longer-term fecal analysis indicates that predation frequency is significantly higher in the dry than in the rainy season. The seasonality of predation might be the result of the sum of various ecological factors, at least one of which is the birth season of the prey species. Most of the prey are juvenile blue duiker, bushbuck, bushpig, red colobus, and red-tailed monkeys. Sex difference is recognized in the prey selection and in the hunting method employed. Apparent local difference in the predatory behavior between Mahale and Combe chimpanzees (in Mahale,females hunt more frequently, and blue duiker is the most frequent prey) can be understood in terms of the difference either in the observation methods or in the faunal diversity and density. Other aspects of predatory behavior also are reported.
