Summary
Chimpanzees at Mount Nimba Strict Nature Reserve exhibit selective behavior when drumming on tree buttresses, favoring larger trees with thinner and broader buttresses. This suggests that buttress drumming is a goal-oriented communication strategy rather than a random act, likely used for long-distance signaling. The study analyzed drumming patterns at the Seringbara site in Guinea, revealing that chimpanzees prioritize buttress characteristics that enhance sound propagation, supporting its role in nonvocal communication within their dynamic social structure.
