Examples of simulation models (see Box 3). (a) Trajectories of the nutritional states (NS) of individuals with the same intake target (IT) presented two complementary foods (grey lines). With moderate social attraction (green), individuals reach their IT by synchronously switching between foods. Without attraction (blue), individuals asynchronously alternate between foods, reaching their IT at a slower rate. With strong attraction (red), individuals stay on the first food they choose. (b) Foraging dynamics of two subgroups of individuals with different IT and moderate attraction in the same environment as (a). During the initial phase of collective foraging, individuals of the subgroup deviating the most from their IT lead the collective switches between foods. (c) Group of individuals with the same IT exploiting three foods. Under no competition, all individuals reach their IT (blue). Competition stretches the NS along the balanced food rail (red). Low food selectivity stretches the NS transversely (green).
