This volume reviews our current understanding of avian population dynamics and explores ways in which population studies can contribute to effective conservation and management. Estimation of demographic parameters, the role of mathematical modelling, and the special problems of island populations and seabird populations are discussed. The emphasis throughout is on how bird populations are regulated under various constraints and conditions, including the impact of environmental changes. This book will be useful and interesting to ornithologists, ecologists, wildlife managers, and population biologists.
