Wild chimpanzees in West Africa repeatedly hurl or strike rocks against specific trees, creating large stone piles at their bases that remain active for more than a decade.
Why Chimpanzees Throw Rocks at Trees
▫️Stone-Assisted Drumming: Adult male chimpanzees hit tree trunks with stones to make loud sounds that travel far through the forest.
▫️Long-Distance Communication: Researchers from institutions like Wageningen University note that this behavior often combines with loud calls called "pant-hoots" to signal locations or claim territory.
▫️Cultural Tradition: Scientists suggest the ritual is a form of animal culture passed down within specific local groups.
▫️Symbolic Display: Because the exact meaning remains a mystery, experts believe the repeated action might have a social, territorial, or even symbolic purpose.
