Documented in Remote Forest in Congo
Hicks et al., Biol. Consv.
Chimps are thriving in a remote Congo forest.
Researchers have documented a huge population of chimpanzees in the Democratic Republic of Congo — a community of perhaps tens of thousands of individuals with its own unique customs and behaviors, the Guardian reports
. The so-called "mega-culture," which spans 50,000 square kilometers of virtually untouched forest, is thought to be the largest population of chimps in Africa and one of the last remaining continuous populations of chimpanzees in the wild, the scientists report
in the journal Biological Conservation
. The researchers first reported on this community in 2007, but their new survey includes detailed videos of the thriving population and its unique behaviors, which include feasting on leopards, using tools to harvest giant African snails and swarming insects, and building ground nests far more frequently than other chimps. While the find is heartening in terms of chimpanzee conservation, the researchers and wildlife advocates fear the population could be decimated by habitat loss and poachers, who stand to make huge profits in the bushmeat trade. The chimps are protected by DRC law, but the region is notoriously volatile and its military and government officials widely viewed as corrupt.
