'Grass-in-the-ear' technique sets new trend in chimp etiquette
Date:7/3/2014

Chimpanzees are copycats and, in the process, they form new traditions that are often particular to only one specific group of these primates. Such are the findings of an international group of scientists, who waded through over 700 hours of video footage to understand how it came about that one chimpanzee stuck a piece of grass in her ear and started a new trend, and others soon followed suit. The findings of the study, led by Edwin van Leeuwen of the Max Planck Institute for Psycholinguistics in The Netherlands, are published in Springer's journal Animal Cognition.

In 2010, van Leeuwen first noticed how a female chimp named Julie repeatedly put a stiff, strawlike blade of grass for no apparent reason in one or both of her ears. She left it there even when she was grooming, playing or resting in Zambia's Chimfunshi Wildlife Orphanage Trust sanctuary. On subsequent visits, van Leeuwen saw that other chimpanzees in her group had started to do the same.

This aroused his interest to find out if they copied what Julie did by watching and learning from her through so-called social learning. The research team, including Zambians who monitor the chimpanzees daily, collected and analyzed 740 hours of footage that had been shot during the course of a year of 94 chimpanzees living in four different social groups in the sanctuary. Only two of these groups could see one another.

The research team found that only one of the four groups regularly performed this so-called "grass-in-the-ear" behavior. In one other group one chimpanzee once did the same. Eight of the twelve chimpanzees in Julie's group repeatedly did so. The first to copy her was her son, Jack, followed by Kathy, Miracle and Val with whom she regularly interacted. Generally at least two of the chimps put grass in their ear at the same time. Interestingly, the chimpanzees Kathy and Val kept up the custom even after Julie, the original inventor of this behavior, died. '/>"/>
