Fluctuations Of A Common Buzzard Buteo Buteo Population In Central Poland

'Based on many years of personal research, and a thorough knowledge of the European literature, the authors provide an eminently readable account of the biology of the Common Buzzard. Whatever your interests in birds, I can recommend this book for its content of information and insight.' – Professor Ian Newton OBE, FRS, FRSE Soaring majestically on thermals with broad wings raised, the Common Buzzard is a familiar sight for many people across Eurasia. In fact, thanks to a remarkable ability to adapt to local conditions, it is now one of the most abundant hawks in the world. The Common Buzzard can exploit a variety of nest sites, and has an eclectic diet that ranges from earthworms and voles to woodpigeons and even deer carcasses. This is a species rich in paradoxes. Why does a hawk evolved for hunting small mammals thrive on invertebrates and carrion? How can a raptor renowned for dramatic territorial displays occur at such high densities? And why does such a large bird that can travel long distances spend so much time in small areas? Sean Walls and Robert Kenward delve deep into the ecology of the Common Buzzard to provide answers to these questions and many more, as well as examining the conservation conundrums raised by this bird. Bringing together a wealth of research on the species' origins, feeding behaviour and breeding, along with information on movement and survival from the authors' own studies, The Common Buzzard provides an invaluable insight into exactly what has enabled this marvellous raptor to return to old haunts to impress, inspire and connect people with nature.

'This long-awaited update to the acclaimed first edition is the definitive guide to a complex and intriguing family. The species accounts and taxonomic treatments have been fully revised in line with recent studies, and the all-new plates and photos complete this remarkable work. Highly recommended.' – Dominic Mitchell Beautiful, colourful, often fearless hunters of large insects and small vertebrates, shrikes are among the most admired of all avian groups. The group is widespread (particularly in the Old World) with a large number of species, though many populations have plummeted in recent years, especially in Europe. This is a second edition of Norbert Lefranc's Shrikes, fully updated from its 1997 predecessor. The introductory texts have been significantly expanded and six new sections have been added in the species accounts: vagrancy, foraging behaviour, breeding success, population trends, conservation and taxonomic notes. Special attention has been given to the latest developments in shrike systematics, not forgotten by the DNA revolution. The species accounts give information about the past and current distribution, along with threats and conservation status. Detailed and fully revised maps accompany the authoritative text, along with hundreds of high-quality photos showcasing racial and ageing differences as well as interesting aspects of shrike behaviour. An exceptional new series of plates by Tim Worfolk have been created, with more individual plumages shown than in the previous edition. This beautiful book represents the definitive account of shrikes and their relationships, appearance, conservation and lifestyle; it will be treasured by birdwatchers and professional ornithologists alike.
