Abstract

During the nonbreeding season, fitness is enhanced primarily by adaptations that promote survival as opposed to reproduction. Adaptations that minimize risks of starvation and predation have been the subject of much theoretical and empirical research during the past decade. Here, we review energy management during the nonbreeding season, paying particular attention to recent theoretical advances and to experimental work designed to evaluate such theory. Energy management consists of adaptations that deal with locating and acquiring resources and also with storing and utilizing them. Energy management includes adaptations concerning the storage of such resources in the bird’s body or in the environment (food-caching birds only) and adaptations that permit optimal use of stored energy to escape death by either starvation or predation (Grubb and Pravosudov, 1994b).
