“Until recently, inferring identities of predators and monitoring cryptic behaviors at the nest was time-consuming, often with anecdotal results. No more. Video nest surveillance, so aptly revealed in this volume, has ushered in a new era of data collection that allows field workers to link environmental factors with such aspects as the temporal dynamics of predator communities in relation to what the birds are doing at their nests, thus removing much of the guesswork of earlier studies.”--Spencer G. Sealy, University of Manitoba "Video Surveillance of Nesting Birds shatters earlier beliefs about how birds interact with nest predators. Much of what we thought we knew about nesting and its hazards was flat-out wrong, as authors in this book discovered by using modern technology in the field. As simple as we would like our models of animal behavior to be, this book shows that reality is far more complex and nuanced."--Douglas H. Johnson, University of Minnesota

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.

A comprehensive monograph on the Atlantic Puffin. With its colourful beak and fast, whirring flight, this is the most recognisable and popular of all North Atlantic seabirds. Puffins spend most of the year at sea, but for a few months of the year the come to shore, nesting in burrows on steep cliffs or on inaccessible islands. Awe-inspiring numbers of these birds can sometimes be seen bobbing on the sea or flying in vast wheels over the colony, bringing fish in their beaks back to the chicks. However, the species has declined sharply over the last decade; this is due to a collapse in fish stocks caused by overfishing and global warming, combined with an exponential increase in Pipefish (which can kill the chicks). The Puffin is a revised and expanded second edition of Poyser's 1984 title on these endearing birds, widely considered to be a Poyser classic. It includes sections on their affinities, nesting and incubation, movements, foraging ecology, survivorship, predation, and research methodology; particular attention is paid to conservation, with the species considered an important 'indicator' of the health of our coasts.

A highly readable Poyser monograph on one of the most widespread raptors. The Osprey is a large, fish-eating bird of prey. Distinctively marked in deep brown and white, with a piercing yellow eye and powerful hooked bill, the Osprey snatches its prey in spectacular swoops above lakes and wetlands around the world it is one of the most widespread of all birds. Persecuted mercilessly in Britain, it became extinct in the 1890s before returning to the famous Loch Garten in Scotland in the 1950s. The return of the bird has been slow, but reintroduction programmes elsewhere notably at Rutland Water have been successful, and this remarkable raptor is an increasingly common sight in our skies. This Poyser monograph is dedicated to this fine species and includes more than 150 colour photographs. The Osprey looks at the distribution, foraging ecology, migration, breeding behaviour and population dynamics of this spectacular bird, with emphasis placed on conservation efforts both in Britain and in the species' African haunts, which have been discovered only very recently thanks to advances in satellite tagging technology.

Provides and analyzes real examples of how structured decision making (SDM) can help solve complex problems involving natural resources. When faced with complicated, potentially controversial decisions that affect our environment, many resource management agencies have come to realize the value of structured decision making (SDM)—the systematic use of principles and tools of decision analysis. Few professionals, however, have extensive experience implementing SDM. Structured Decision Making provides key information to both current adopters of the method and those who are deploying it for the first time by demonstrating the formal use of decision analysis to support difficult, real-world natural resource management decisions. Drawing on case studies from multiple public agencies in the United States, Canada, Australia, and Mauritius, the editors present an overview of decision analysis, a classification of decision types, and a catalog of decision analysis methods. Dozens of detailed charts and maps help contextualize the material. These case studies examine a rich variety of topics, including • keeping forest birds free from disease • conserving imperiled freshwater mussels • managing water for oil sands mining • dealing with coastal wetlands in the face of sea-level rise • designing networks for prairie-dependent taxa • combatting invasive alpine shrubs • managing vernal pool habitats for obligate amphibian species • and much more Aimed at decision makers tackling natural resource challenges in government agencies around the world, as well as advanced undergraduate and graduate students preparing to work in natural resource management, Structured Decision Making shows how SDM can be implemented to achieve optimal outcomes that integrate social values and scientific understanding.

Drawing on detailed data from their sixteen-year study of red-winged blackbirds in the marshes of Washington's Columbia National Wildlife Refuge, Beletsky and Orians analyze the information redwings use to make breeding-season decisions and the consequences these decisions have for lifetime reproductive success. Because male and female redwings make different, and often independent, decisions—males focus on territory acquisition and maintenance, while females must choose when and where to nest and how much energy to invest in reproduction—the authors have taken the novel approach of studying the sexes separately. Using analyses of observational data combined with field experiments and game-theoretical models, the authors provide new insights into the complex patterns of reproductive decision-making and breeding behavior in redwings. This book will be of interest to all who study social animals, including behavioral ecologists, evolutionary biologists, and ornithologists.

Physiological Adaptations for Breeding in Birds is the most current and comprehensive account of research on avian reproduction. It develops two unique themes: the consideration of female avian reproductive physiology and ecology, and an emphasis on individual variation in life-history traits. Tony Williams investigates the physiological, metabolic, energetic, and hormonal mechanisms that underpin individual variation in the key female-specific reproductive traits and the trade-offs between these traits that determine variation in fitness. The core of the book deals with the avian reproductive cycle, from seasonal gonadal development, through egg laying and incubation, to chick rearing. Reproduction is considered in the context of the annual cycle and through an individual's entire life history. The book focuses on timing of breeding, clutch size, egg size and egg quality, and parental care. It also provides a primer on female reproductive physiology and considers trade-offs and carryover effects between reproduction and other life-history stages. In each chapter, Williams describes individual variation in the trait of interest and the evolutionary context for trait variation. He argues that there is only a rudimentary, and in some cases nonexistent, understanding of the physiological mechanisms that underpin individual variation in the major reproductive life-history traits, and that research efforts should refocus on these key unresolved problems by incorporating detailed physiological studies into existing long-term population studies, generating a new synthesis of physiology, ecology, and evolutionary biology.
