Tamarins and chimpanzees differ in many aspects of their behavior, biology, and evolutionary history; however, both primates are heavily dependent on a diet of ripe fruits during all months of the year (reviewed in Digby et al. 2011; Stumpf 2011). In addition, previous research on cognition in tamarins and chimpanzees indicates that individuals retain spatial information concerning the location of many feeding sites (e.g., Garber 2000; Janmaat et al. 2013a; Normand et al. 2009). Since primates show a high level of site fidelity (Janmaat et al. 2009) and commonly rely on sessile food sources that are revisited many times over a limited part of the year (such as termite nests and trees producing fruits, leaves, flowers, and/or exudates), one might expect foragers to reuse a limited set of travel routes, return to previously visited feeding sites, and search for new food patches in locations nearby current feeding sites.
