  • The optimization approach to foraging is, by definition, concerned with the benefits and costs associated with feeding. The benefits to a predator are relatively easy to determine; they can, for example, be measured in terms of the weight or energy content of the food received. Measurement of costs however, has proven more difficult. Recently Werner and Hall (1974), followed by Kislalioglu and Gibson (1976), Stein (1977), and Elmer and Hughes (1978), have estimated costs as the time spent… CONTINUE READING
