Optimal foraging

Abstract

Before visiting your local supermarket, do you write your food shopping list in the order you expect to encounter the items as you walk around, aisle by aisle? This way, you minimise your travel distance, saving time and effort. Many other animals do the same. Baboons (Papio ursinus) plan their foraging journeys to out-of-sight resources, moving in an efficient, goal-directed way, and nectar-collecting bumble bees (Bombus impatiens) use efficient travel routes when foraging on familiar resources.
