Please read a brief article we published recently about “hand-clasp grooming” performed by some of the released chimpanzees. This article is available online at: http://mahale.web.infoseek.co.jp/PAN/16_1/16(1)_03.html
We witnessed this behavior when Rappa and Albert were reunited and it was quite astonishing for us to see this really particular grooming behavior. Handclasp grooming is a behavior which has before been described elsewhere at a few wild chimpanzee study sites, especially in East Africa. But not all wild chimpanzee communities display this behavior! It is truly a social custom, a cultural behavior unique to some chimpanzee communities!More data are being gathered on this behavior as we speak and it appears now that it is spreading among some of the released chimpanzees. It is fascinating to see rehabilitated chimpanzees being able to innovate and propagate new behaviors…Culture in the making!![]()

Project Primate, Inc. provides support to the Chimpanzee Conservation Center in Guinea which serves as a chimpanzee rehabilitation sanctuary for orphaned and confiscated western chimpanzees and has as its primary objectives the release of these orphans back into the wild and the protection of a national park.
