The identification, ecology and biology of the ducks of Europe. The forty-two species or subspecies of ducks which occur in Europe, including eleven vagrants from North America or Asia, are the subject of this book. Its author is an accepted authority on ducks and geese, and has been a member of the research staff of the Wildfowl Trust at Slimbridge since 1960. Most birdwatchers consider ducks to be especially attractive and interesting birds, and many species of ducks are also the legitimate quarry of wildfowlers. Both groups need to identify the species quickly and accurately, and almost half of the book is devoted to identification, offering a far more detailed account than is to be found in any of the field guides. There are detailed descriptions, species by species, of the adult males and females, immature birds, eclipse males, and downy young - voice, too, is dealt with - and full-colour plates of males and females show the flight patterns, so important for correct species identification. The habits of European ducks are treated in chapters on behaviour and ecology, breeding biology, distribution and status, and the ever-fascinating topic of migration and navigation. The distribution chapter has maps showing the summer and winter ranges in Europe, North Africa, the Middle East and Central Russia, for 24 species. A final chapter considers the present day threats to ducks and their wetland habitats, and the conservation measures being taken to combat the threats. The colour plates and more than 80 line drawings in the text are by Carol Ogilvie, the author's wife. Jacket illustration by Carol Ogilvie.

The #1 selling wildlife management book for 40 years, now updated for the next generation of professionals and students. Since its original publication in 1960, The Wildlife Techniques Manual has remained the cornerstone text for the professional wildlife biologist. Now fully revised and updated, this eighth edition promises to be the most comprehensive resource on wildlife biology, conservation, and management for years to come. Superbly edited by Nova J. Silvy and published in association with The Wildlife Society, the 50 authoritative chapters included in this work provide a full synthesis of methods used in the field and laboratory. Chapter authors, all leading wildlife professionals, explain and critique traditional and new methodologies and offer thorough discussions of a wide range of relevant topics. To effectively incorporate the explosion of new information in the wildlife profession, this latest edition is logically organized into a 2-volume set: Volume 1 is devoted to research techniques and Volume 2 focuses on pragmatic management methodologies. Volume 1 describes research design and proper analytic methods prior to conducting research, as well as methods and considerations for capturing and handling wild animals and information on identification and marking of captured animals. It also includes new chapters on nutritional research and field sign identification, and on emerging topics, including structured decision-making. Finally, Volume 1 addresses measurements of wildlife abundance and habitat and research on individual animals. Volume 2 begins with a section on the relationship between research and management including public outreach, described in a context that encourages engagement prior to initiation of management. An adaptive management approach is described as a cornerstone of natural resource management, followed by a section on managing landscapes and wildlife populations. The volume also includes new chapters on ethics in wildlife science and conservation, conflict resolution and management, and land reclamation. A standard text in a variety of courses, the Techniques Manual, as it is commonly called, covers every aspect of modern wildlife management and provides practical information for applying the hundreds of methods described in its pages. This deft and thorough update ensures that The Wildlife Techniques Manual will remain an indispensable resource, one that professionals and students in wildlife biology, conservation, and management simply cannot do without.
