The ability to navigate through both familiar and unfamiliar environments is of critical importance for foraging efficiency, safety, energy budgeting in wild animals. For animals that remain the same home range annually, such as grey-footed chacma baboons (Papio ursinus griseipes), movement efficiency expected reflect familiarity with well nature resources within it. example, are patchy, transient, or seasonal present a greater spatial cognitive challenge, travel between them may be less efficient than more widespread permanent resources. Here, we analyse daily route adult female at Gorongosa National Park, Mozambique. We use GPS data taken 15 min intervals from collars deployed on two each study troops (four total) identify areas interest used during ranging periods (sleep site sleep site). then compare length given day’s patches routes calculated by alternate optimisation heuristics follows: nearest neighbour method, which subject repeatedly travels next most proximate patch does not necessarily return place, Concorde algorithm, calculates shortest possible connecting patches. show those yielded nearest-neighbour heuristic but implying some degree planning. discuss our novel method area identification using only remote data, implications findings primate cognition.
