The seabird's cry : the lives and loves of the planet's great ocean voyagers
\"Even as we are coming to understand them, the number of seabirds on our planet is in freefall, dropping by nearly 70% in the last sixty years, a billion fewer now than there were in 1950. Of the ten birds in this book, seven are in decline, at least in part of their range. Extinction stalks the ocean and there is a danger that the grand cry of the seabird colony, rolling around the bays and headlands of high latitudes, will this century become little but a memory ... Over the last couple of decades, modern science has begun to understand their epic voyages, their astonishing abilities to navigate for tens of thousands of miles on featureless seas, their ability to smell their way towards fish and home\"--Amazon.com.

Physiological adaptations for breeding in birds
Physiological Adaptations for Breeding in Birdsis 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.

Sparrow
In Sparrow, award-winning science and natural history writer Kim Todd explores the bird\"s complex history, biology, and literary tradition. Todd describes the difference between Old World sparrows, like the house sparrow, which can nest in a garage or in an airport, and New World sparrows, which often stake their claim to remote islands or meadows in the high Sierra. In addition, she looks at the nineteenth-century Sparrow War in the United States--a battle over the sparrow\"s introduction--which set the stage for decades of discussions of invasive species. She examines the ways in which sparrows have taught us about evolution and the shocking recent decline of house sparrows in cities globally--this disappearance of a bird that seemed hardwired for success remains an ornithological mystery.
Book
migration ecology of birds
This book presents an up-to-date, detailed and thorough review of the most fascinating ecological findings of bird migration. It deals with all aspects of this absorbing subject, including the problems of navigation and vagrancy, the timing and physiological control of migration, the factors that limit their populations, and more. Author, Ian Newton, reveals the extraordinary adaptability of birds to the variable and changing conditions across the globe, including current climate change. This adventurous book places emphasis on ecological aspects, which have received only scant attention in previous publications. Overall, the book provides the most thorough and in-depth appraisal of current information available, with abundant tables, maps and diagrams, and many new insights. Written in a clear and readable style, this book appeals not only to migration researchers in the field and Ornithologists, but to anyone with an interest in this fascinating subject. * Hot ecological aspects include: various types of bird movements, including dispersal and nomadism, and how they relate to food supplies and other external conditions * Contains numerous tables, maps and diagrams, a glossary, and a bibliography of more than 2,700 references* Written by an active researcher with a distinguished career in avian ecology, including migration research

Winged Sentinels
'The ability of the birds to show us the consequences of our own actions is among their most important and least appreciated attributes. Despite the free advice of the birds, we do not pay attention', said Marjory Stoneman Douglas in 1947. From ice-dependent penguins of Antarctica to songbirds that migrate across the Sahara, birds' responses provide early warning signs of the impact of climate change. Winged Sentinels: Birds and Climate Change uses colourful examples to show how particular groups of birds face heightened threats from climate change and to explore how we can help birds adapt in a warming world. Generously illustrated with colour photographs, the book is a fascinating insight into what climate change means for birds, and the potential consequences of ignoring these warning signs.

albatross and the fish
Breeding on remote ocean islands and spending much of its life foraging for food across vast stretches of seemingly empty seas, the albatross remains a legend for most people. And yet, humans are threatening the albatross family to such an extent that it is currently the most threatened bird group in the world. In this extensively researched, highly readable book, Robin W. Doughty and Virginia Carmichael tell the story of a potentially catastrophic extinction that has been interrupted by an unlikely alliance of governments, conservation groups, and fishermen. Doughty and Carmichael authoritatively establish that the albatross's fate is linked to the fate of two of the highest-value table fish, Bluefin Tuna and Patagonian Toothfish, which are threatened by unregulated commercial harvesting. The authors tell us that commercial fishing techniques are annually killing tens of thousands of albatrosses. And the authors explain how the breeding biology of albatrosses makes them unable to replenish their numbers at the rate they are being depleted. Doughty and Carmichael set the albatross's fate in the larger context of threats facing the ocean commons, ranging from industrial overfishing to our habit of dumping chemicals, solid waste, and plastic trash into the open seas. They also highlight the efforts of dedicated individuals, environmental groups, fishery management bodies, and governments who are working for seabird and fish conservation and demonstrate that these efforts can lead to sustainable solutions for the iconic seabirds and the entire ocean ecosystem.

Urban bird ecology and conservation
Now that more than half of the world's population lives in cities, the study of birds in urban ecosystems has emerged at the forefront of ornithological research. An international team of leading researchers in urban bird ecology and conservation from across Europe and North America presents the state of this diverse field, addressing classic questions while proposing new directions for further study. Areas of particular focus include the processes underlying patterns of species shifts along urban-rural gradients, the demography of urban birds and the role of citizen science, and human-avian interaction in urban areas. This important reference fills a crucial need for scientists, planners, and managers of urban spaces and all those interested in the study and conservation of birds in the world's expanding metropolises.

Boreal birds of North America
Reaching from interior Alaska across Canada to Labrador and Newfoundland, North America's boreal forest is the largest wilderness area left on the planet. It is critical habitat for billions of birds; more than 300 species regularly breed there. After the breeding season, many boreal birds migrate to seasonal habitats across the United States, Mexico, the Caribbean, and Central and South America. This volume brings together new research on boreal bird biology and conservation. It highlights the importance of the region to the global avifauna and to the connectivity between the boreal forest and ecoregions throughout the Americas. The contributions showcase a unique set of perspectives on the migration, wintering ecology, and conservation of bird communities that are tied to the boreal forest in ways that may not have been previously considered.
