In this first comprehensive synthesis of the literature on food hoarding in animals, Stephen B. Vander Wall discusses how animals store food, how they use food and how this use affects individual fitness, why and how food hoarding evolved, how cached food is lost, mechanisms for protecting and recovering cached food, physiological and behavioral factors that influence hoarding, and the impact that hoarding animals have on plant populations and plant dispersal. He then provides detailed coverage of hoarding behavior across taxa—mammals, birds, and arthropods—to address issues in evolution, ecology, and behavior. Drawings, photographs, and appendixes document complex and intrinsically interesting food-hoarding behaviors, and the bibliography of nearly 1,500 sources is itself an invaluable and unique reference.
