Africa-Press – Mauritius. <\/strong><\/span>Wild chimpanzees have their own \u201csignature drumming style\u201d according to scientists. Researchers who followed and studied chimps in the Ugandan rainforest found that the animals drum out messages to one another on tree roots.<\/p>\n

The scientists say that the signature rhythms allow them to send information over long distances, revealing who is where, and what they are doing. The findings are published in the journal Animal Behaviour.<\/p>\n

Dr Catherine Hobaiter from the University of St Andrews explained that the wild apes use huge tree roots as a large wooden surface to drum on with their hands and feet.<\/p>\n

\u201cIf you hit the roots really hard, it resonates and makes this big deep, booming sound that travels through the forest,\u201d she told BBC Radio 4\u2019s Inside Science programme.<\/p>\n

\u201cWe could often recognise who was drumming when we heard them; it was a fantastic way to find the different chimpanzees we were looking for. So if we could do it, we were sure they could too.\u201d<\/p>\n

Each male chimpanzee, the scientists found, uses a distinct pattern of beats. They combine it with with long-distance vocalisations, called pant-hoots. And different animals drum at different points in their call.<\/p>\n

Lead researcher on this study, PhD student Vesta Eleuteri from the University of Vienna, described how some individuals have a more regular rhythm, like rock and blues drummers, while some have more variable rhythms, like jazz.<\/p>\n

\u201cI was surprised that I was able to recognise who was drumming after just a few weeks in the forest,\u201d she said. \u201cBut their drumming rhythms are so distinctive that it\u2019s easy to pick up on them.\u201d<\/p>\n

Ms Eleuteri described one young male chimp, that researchers have named Tristan, as \u201cthe John Bonham (late Led Zeppelin drummer) of the forest\u201d. \u201cHe makes these very long drumming bouts with lots of beats and you can tell them from far away, so you can just tell it\u2019s Tristan drumming.\u201d<\/p>\n

The animals also appeared only to use their signature rhythm when they were travelling. The researchers speculate that a chimp chooses whether or not to give his identity away.<\/p>\n

\u201cIf you\u2019re showing off to a group around you \u2013 if you\u2019re displaying \u2013 you might not necessarily want the big alpha male who\u2019s around the corner to know who you are,\u201d said Dr Hobaiter. \u201cYou don\u2019t want to give the game away.\u201d<\/p>\n

She added that understanding chimps\u2019 drumming in this way could solve a longstanding communication puzzle: wild chimpanzees greet each other when they meet, but they do not seem to \u201csay goodbye\u201d when they split off in the forest.<\/p>\n

\u201cThe chimps might not need to say goodbye, because they\u2019re effectively able to keep in touch while they\u2019re away,\u201d Dr Hobaiter explained.<\/p>\n

\u201cThese long distance signals give the chimps a way to check in with one another. That might help us to understand one of these things that we thought was a real difference between chimps and humans, and help us to understand why that difference might have come about.\u201d<\/p>\n
