Animal behaviour is the scientific study of everything animals do, whether the animals are single-celled organisms, invertebrates, fish, amphibians, reptiles, birds, or mammals. It involves investigating the relationship of animals to their physical environment as well as to other organisms, and includes such topics as how animals find and defend resources, avoid predators, choose mates and reproduce, and care for their young. This book provides a broad overview of the current state of animal behaviour for undergraduate and postgraduate courses in zoology, veterinary science and other allied fields. It provides all the basic concepts and latest information on animal behaviour. Contents: Preface. 1. Ecology of animal behaviour. 2. Development of physical structure. 3.
