The original version of this article unfortunately contained a mistake. The Funding information section was missing and should have read:

Funding This work has been developed within the project “A survey of Chimpanzee Material Culture in Eastern DR Congo” financed by the National Science Center, Poland on the basis of the Decision no. DEC-2017/25/B/NZ8/02730.

The original article has been corrected.
