Abstract

An optimal foraging model is presented which combines simultaneous and nonsimultaneous modes of search for food. This model is more complex than those in the literature which are constructed using one search mode exclusively. Solutions to this foraging model lead to diets which are seldom composed of a single food or of foods in proportion to their abundance in the environment. Therefore, the most commonly cited qualitative conclusions of optimal foraging theory are not adequate to explain foraging choices under the range of probable search modes.
