This article deals with foraging theory, a subdiscipline of Behavioural Ecology that elucidates why and how animals exploit food. In particular, it seeks to explain the adaptive significance of foraging strategies wherein individuals employ particular suites of tactics that lead to maximizing Darwinian fitness via accessing and assimilating foodstuffs. These rules involve methods that animals use for searching for foodstuffs as well as for discriminating among foodstuffs based upon energetic profitability.
