For example, a bird might forage at a berry bush; stay too long and the initially abundant fruit is increasingly difficult to find, requiring more energy. Suppose the patch energy function is given by Emaxt f. (1 ) = k+ t' where Emax, k > 0 are constants. Further, the amount of time spent going out to forage is described by 8 (t) = (7 + 1), where t is a fixed travel time between patches and t 2 0 is the time spent foraging at a patch. We can combine these to form a function that describes the amount of energy gained per unit time spent foraging: Energy gained R(t) = f(1) Time spent foraging g(t) Plot this function and find the optimal foraging time.
