The Australian Zebra Finch is widely used by researchers and teachers in many scientific disciplines where it is the preferred subject for investigations ranging from anatomy and physiology to behavioural development and evolutionary ecology. This monograph is the first to synthesize the information on this colourful species that has accumulated during the past thirty years. It summarizes and integrates much of the laboratory work and places it in the context of the biology of the animals in the wild, with an emphasis on behaviour and ecology. This leads to a detailed understanding of Zebra Finch adaptations and life history that will further enhance the value of the species for researchers and students in behaviour, ecology, and other fields. Aviculturists who keep these attractive birds will also find much of interest in this book.
