Pan t.的捕食行为直接观察和粪便证据都证实了Ndoki森林中的troglodytes。在16个月内收集的214份粪便样本中有8份（3.7%）含有脊椎动物组织。猎物是一种陆地鸟类、两种猴子（包括冠长尾猴）、一只松鼠，可能还有一只穿山甲。这一比率表明，Ndoki种群中的捕食可以像其他种群一样频繁地发生。黑猩猩也被直接观察到吃一只幼年冠尾猴、一只犀鸟和一只小羚羊。一只成年雌性用一根分支显然是想把一只犀鸟从窝里赶出来，但没有观察到鸟出来。黑猩猩被肉类所吸引，并被观察到乞讨和分享肉类。捕食行为在人属和人属中普遍存在，但在大猩猩中不存在，这意味着前两个属的共同祖先在从大猩猩中分离出来后获得了这种行为。
Predatory behavior ofPan t. troglodytesin the Ndoki Forest was confirmed by both direct observation and fecal evidence. Eight out of 214 fecal samples (3.7%), collected during 16 months, contained vertebrate tissue. The prey species were a terrestrial bird, two monkey species including crowned guenon, a squirrel, and probably a pangolin. This rate suggested that predation in the Ndoki population can occur as frequently as in other populations. Chimpanzees were also directly observed to eat an infant crowned guenon, a hornbill, and a duiker. An adult female used a branch apparently in an attempt to drive out a hornbill from its nest hole, though no bird was observed to come out. Chimpanzees were attracted to meat, and were observed begging and sharing over the meat. Predatory behavior is common toPanandHomo, but not toGorilla, implying that the common ancestor of the former two genera acquired this behavior after separating from gorillas.
