All of life forages for resources that are needed for survival, development, and reproduction. Optimal foraging theory (OFT) aims to understand foraging behavior by hypothesizing that animals forage in ways such that some currency, such as net rate of energy intake, could not be improved with an alternative strategy [21, 22, 23]. Choosing an appropriate currency is all-important. For more than 50 years, OFT has provided evolutionary explanations for observed foraging behavior, to the point that it can be considered a strong theory of behavior and ecology [22, 23].
OFT takes two forms: classical OFT, which applies to solitary foragers, and foraging game theory, which applies to social species. In the former, individuals are assumed to forage independently of each other, so that an individual does not respond directly to the behavior of neighbors. If, however, individuals respond directly to the behavior of others, then all individuals are involved in a “game,” as the outcomes for...
