人们花了两个月的时间在利比里亚东部的萨波森林调查黑猩猩。根据样带上发现的巢的数量估计的种群密度似乎低于其他林地。巢更类似于其他生活在森林中的黑猩猩的巢，而不是草原种群的巢。巢多分布在原始林区。发现了黑猩猩用石头作为锤子敲开四种坚果的证据；萨波黑猩猩和象牙海岸泰森林的黑猩猩在这种行为中使用的材料和技术可能有所不同。对粪便的分析表明，萨波黑猩猩吃肉。
Two months were spent surveying for chimpanzees (Pan troglodytes verus) in the Sapo Forest, eastern Liberia. The population density, as estimated from the number of nests found on transects, appears lower than that in other forest sites. Nests were more similar to those of other forest-living chimpanzees than of a savannah population. Most nests were found in areas of primary forest. Evidence was found of the chimpanzees using stones as hammers to break open four species of nut; there may be differences in materials and techniques used in this behaviour between Sapo chimpanzees and those in Tai Forest, Ivory Coast. Analysis of faeces revealed that Sapo chimpanzees eat meat.
