DOWNLOAD EBOOK →There are more than one thousand species of threatened birds in the world, while many others are valued for sport and some are serious pests. 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.

DOWNLOAD EBOOK →Point counts of birds are the most widely used quantitative method and involve an observer recording birds from a single point for a standardized time period. In response to the need for standardization of methods to monitor bird populations by census, researchers met to present data from various investigations working under a wide variety of conditions, and to examine various aspects of point count methodology. Statistical aspects of sampling and analysis were discussed and applied to the objectives of point counts. The final chapter presents these standards and their applications to point count methodology.

DOWNLOAD EBOOK →Dr Newton's book is concerned with all aspects of population regulation in diurnal birds of prey, their social behaviour, dispersion, numbers, movements, breeding and mortality. He has drawn on his own studies in Scotland and on material and investigations worldwide to produce an authoritative and stimulating synthesis of current thinking and research on the ecological problems of the Falconiformes. He also deals in detail with the effects of pesticides and other pollutants on these birds, and with their scientific management and conservation. The author's lucid style will ensure a wide readership among research workers and the more general audience with an interest in birds of prey. There is a full bibliography and an extensive appendix of tables.
