“…The second tool was found in close proximity to the Anogeissus tree crown, similar to what is seen at the Fongoli site when 'spear' tools are discarded. All hunting, termite fishing, and ant dipping tools were found in the eastern side of the Bantan community's range based on 2017 nesting data (Micheletti 2018). Furthermore, the hunting tools were found on June 22, which is considered the wet season, and when most tool-assisted hunting practices are observed at Fongoli (Pruetz et al 2015).…”

“…The Bantan chimpanzee community is an unhabituated group that has been sporadically studied via indirect observational methods since 2000. There are estimated to be approximately 20 individuals in the group, based on nesting data collected in previous studies (Pruetz unpublished data;Micheletti 2018). Ndiaye and students have been conducting research on this community since 2016 (Ndiaye et al 2018;Diallo 2019).…”

“…The focus during the study, lasting from May through August 2017, was to survey for signs of chimpanzees in this area and to assess any anthropogenic threats to them (Micheletti 2018). Sixteen reconnaissance walks were conducted to find evidence of chimpanzee´s presence.…”

Chimpanzees use tools extensively, but tool-assisted hunting has been reported at only two sites thus far. Systematic tool-assisted hunting has only been recorded at the Fongoli site in Senegal, where hundreds of cases have been recorded of chimpanzees using tools to hunt bushbaby (Galago senegalensis) prey. Here, we report a putative case of tool-assisted hunting at the Bantan study site in southeastern Senegal, based on indirect evidence of tools and tool-making traces in a context similar to that observed at neighboring Fongoli chimpanzee community. If our interpretations are correct, the simplest explanation is that Fongoli females have dispersed to this neighboring community, bringing with them the behavior of tool-assisted hunting. However, the persistence and frequency of tool-assisted hunting at other sites in Senegal is still unknown. Tool-assisted hunting in the Bantan chimpanzee community would present only the third such known site for such behavior among wild chimpanzees thus far.
