Comparison of range use during daily foraging trips of (A) the Mbendjele people and (B) Taï chimpanzees. Zoomed-in maps: An example of a one-day foraging trip of (A) one focal woman (black and red lines) and (B) one focal chimpanzee (red line), with off-trail trajectories (in red) towards and away from off-trail food trees (red circles). Inlets: Grey lines show all recorded trajectories during our observation period (Mbendjele: 236 days, Taï chimpanzees: 274 days). The grey colour intensity of a trajectory corresponds to its usage frequency (darker grey corresponds to a more repeatedly-used path). Range area estimation via minimum convex polygon (MCP, beige polygons) and kernel density limits with 95% (pink) and 50% (dark red) coverage probability. The total lengths of all ranging tracks used to calculate daily travel distance and range size were 1,119 km for five Mbendjele women, and 1,255 km for five female chimpanzees, respectively. The legends are for both the zoomed-in map and the inlet.
