Using parsimonious individual-based simulations, we show that for species withspatial cognitive abilities, individual-level memory of resource availability can be sufficient tocause spatial segregation in the foraging ranges of colonial animals. The shapes of the foragingdistributions are governed by commuting costs, the emerging distribution of depleted resources,and the fidelity of foragers to their colonies. When colony fidelity is weak, and foragers caneasily switch to colonies located closer to favorable foraging grounds, this leads to spacepartitioning with equidistant borders between neighboring colonies. In contrast, when colonyfidelity is strong, for example because larger colonies provide safety in numbers or individualsare unable to leave, it can create a regional imbalance between resource requirements andresource availability. This leads to non-trivial space-use patterns that propagate through thelandscape. Interestingly, while better spatial memory creates more defined boundaries betweenneighboring colonies, it can lower the average intake rate of the population, suggesting apotential trade-off between an individual’s strive for increased intake and population growthrates.
