Optimal foraging

Definition

A theory in ecology that predicts animals will choose behaviors that maximize their net return on foraging expenditure.

Etymology

From the combination of 'optimal' meaning 'best' or 'most efficient' and 'foraging' which refers to the act of searching for and consuming food.

Example

A bird might choose to forage in a patch of berries where the density is highest, even if it means spending more time defending the patch from other birds.
