First published in 1983 to celebrate the centennial of the American Ornithologists' Union, Perspectives in Ornithology collects together a series of essays and commentaries by leading authorities about especially active areas of research on the biology of birds. Readers will find in this collection a useful overview of many major concepts and controversies in ornithology.

This book describes the results of a long-term study of the ecology, evolutionary genetics and sociobiology of a seabird, the Arctic Skua. This species is polymorphic: the birds show one of three, genetically different forms of plumage - pale, intermediate and dark. The forms vary in frequency from predominantly pale in the north to dark in the south. The study was undertaken with the aim of explaining how natural and sexual selection act to maintain all three forms of skua in its populations. The results show that natural selection for pale is balanced by sexual selection for intermediate and dark. Models derived from Darwin's theories of female choice and sexual selection in monogamous birds fit the breeding data of the Arctic Skua. Darwibn's views on sexual selection are fully confirmed. The study produced original data on breeding ecology, demography, population regulation, sexual behaviour and territoriality. A chapter on feeding ecology is also included in the book, which gives a complete and largely original account of the population ecology and sociobiology of a single species of bird.

The Wildfowl Trust (founded by Sir Peter Scott in 1946) has worked actively to promote wildfowl conservation over many years and this volume will surely be recognised as one of its finest achievements. Here in one volume the Wildfowl Trust, supported by the Nature Conservancy Council, presents a synthesis of detailed data collected by a wide range of enthusiasts on the distribution of wildfowl and their major habitats. The importance of sensitive conservation planning is stressed as is the vulnerability of wetlands to modern technology. The international dimension of wildfowl conservation is also well covered, especially by the clear maps of ringing recoveries and migration routes. This book emphasises the need for international action in conserving wetlands and stresses the benefits enjoyed by the fortunate countries endowed with these habitats. By their very presence the spectacular flocks of wildfowl provide one of the strongest arguments to convince laymen, planners and politicians that our wetlands are not wastelands but a very precious and vulnerable part of our heritage.

The aim of the authors in writing this monograph has been to provide a comprehensive and critical, but personal account of salt glands. Papers on salt glands are scattered through a great many different journals. There is therefore a great need for a synthesis of what is known about salt glands. The means by which salt glands perform their vital function of forming and excreting a concentrated salt solution is of great biological importance in understanding salt and water relations in the cells of all living things. In addition to the basic physiology of salt glands there is consideration of their ecological importance, their interaction with other systems of the body, their role in non-marine birds and reptiles and their evolution. Salt glands have interested biologists from a wide range of disciplines. This book brings together the scattered literature and will be a convenient source of reference to those working in the field, as well as providing information for comparative studies and for teaching purposes.

In the last few years there has been an excltmg upsurge in seabird research. There are several reasons for this. Man's increased ex ploitation of natural resources has led to a greater awareness of the potential conflicts with seabirds, and of the use of seabirds to indicate the damage we might be doing to our environment. Many seabird populations have increased dramatically in numbers and so seem more likely to conflict with man, for example through competition for food or transmission of diseases. Oil exploration and production has resulted in major studies of seabird distributions and ecology in relation to oil pollution. The possibility that seabirds may provide information on fish stock biology is now being critically investigated. Some seabird species have suffered serious declines in numbers and require conservation action to be taken to reduce the chances that they will become extinct. This requires an understanding of the factors determining their population size and dynamics."

Originally published in 1986, this book is concerned with the ways in which seabirds function as predators in the marine environment; in particular about how they find and catch food and how much of it they consume. It reviews both the feeding ecology of seabirds (including adaptations for flight and diving) and also most of the leading field studies (in polar, temperate and tropical regions) that have quantitatively examined the interactions of seabird communities with their prey.

Winner of the Richard Jefferies Society and White Horse Book Shop Literary Prize 'splendid' -Guardian 'visionary' -New Statesman Britain has all the space it needs for an epic return of its wildlife. Only six percent of our country is built upon. Contrary to popular myth, large areas of our countryside are not productively farmed but remain deserts of opportunity for both wildlife and jobs. It is time to turn things around. Praised as 'visionary' by conservationists and landowners alike, Rebirding sets out a compelling manifesto for restoring Britain's wildlife, rewilding its species and restoring rural jobs - to the benefit of all.

Graham Martin takes the reader deep into the world of birds from a new perspective, with a 'through birds' eyes' approach to ornithology that goes beyond the traditional habitat or ecological point of view. There is a lot more to a bird's world than what it receives through its eyes. This book shows how all of the senses complement one another to provide each species with a unique suite of information that guides their daily activities. The senses of each bird have been fine-tuned by natural selection to meet the challenges of its environment and optimise its behaviour: from spotting a carcase on a hillside, to pecking at minute insects, from catching fish in murky waters, to navigating around the globe. The reader is also introduced to the challenges posed to birds by the obstacles with which humans have cluttered their worlds, from power lines to windowpanes. All of these challenges need explaining from the birds' sensory perspectives so that effective mitigations can be put in place. The book leads the reader through a wealth of diverse information presented in accessible text, with over 100 colour illustrations and photographs. The result is a highly readable and authoritative account, which will appeal to birdwatchers and other naturalists, as well as researchers in avian biology. The author has researched the senses of birds throughout a 50-year career in ornithology and sensory science. He has always attempted to understand birds from the perspective of how sensory information helps them to carry out different tasks in different environments. He has published papers on more than 60 bird species, from Albatrosses and Penguins, to Spoonbills and Kiwi. His first fascination was with owls and night time, and owls have remained special to him throughout his career. He has collaborated and travelled widely and pondered diverse sensory challenges that birds face in the conduct of different tasks in different habitats, from mudflats and murky waters, to forests, deserts and caves. In recent years he has focused on how understanding bird senses can help to reduce the very high levels of bird deaths that are caused by human artefacts; particularly, wind turbines, power lines, and gill nets.

The science of genetics has undergone a period of very rapid and significant development in recent years, and the area of poultry genetics has been no exception. This book provides a balanced and up-to-date account of all the major areas of this subject from Mendelian to modern molecular genetics. The book begins by tracing the evolution of the domestic fowl (Gallus domesticus) from its avian ancestors. Subsequent chapters cover important aspects of poultry genetics, including cytogenetics, transmission genetics, gene mapping, sex linkage, lethal genes, genetics of feathering and plumage, and quantitative genetics. In each chapter, a concise explanation of the genetic principles is followed by a full discussion illustrated by key examples. In the latter part of the book, recent advances in gene cloning and sequencing are examined. In the area of molecular genetics, where the most rapid developments have been made, more extensive background information is given and a glossary of terms is included. The impact of these exciting new developments on our understanding of gene structure and organization, immunogenetics, and the evolution of proteins is assessed. Finally, the uses of transgenic techniques and their implications are discussed. This book provides a clear and useful survey of the genetics and evolution of the domestic fowl, which will be of interest to postgraduate students and researchers in the fields of genetics, agriculture, and veterinary medicine, as well as to poultry breeders, both commercial and non-commercial.

The biology of birds is diverse and frequently differs significantly from that of other vertebrates. Many birds migrate or fly at high altitudes, while egg-laying and feather production places high demands on nutrient uptake and storage. This book is the only comprehensive and up-to-date survey of avian biochemistry and molecular biology available. It emphasises the similarities and differences between birds and other vertebrates, concentrating on new developments. The first section deals with protein, lipid and carbohydrate metabolism, its hormonal control and the adaptations that occur in birds. The second covers the avian genome, gene expression, and avian immunology. Growth and embryological development are also discussed. Avian Biochemistry and Molecular Biology will be of interest to all those working on birds, especially postgraduate students and researchers.

Biological invaders represent one of the primary threats to the maintenance of global biodiversity, human health, and the success of human economic enterprises. The continuing globalization of our society ensures that the need to understand the process of biological invasion will only increase in the future. There is also a growing recognition that the study of biological invaders provides a unique insight into basic questions in ecology and evolution.
The study of exotic birds has had a particularly long history and has come to represent a fascinating intersection between the study of biological invasions, avian conservation biology, and basic principles of ecology and evolution. Avian Invasions summarizes and synthesizes this unique historical record and unravels the insights that the study of exotic birds brings to all three of these research strands. It includes chapters on the well-known contributions of exotic bird study to ecological science, and on the post-establishment evolution of introduced bird populations. The result is the most comprehensive picture yet of the invasion process.
Avian Invasions is aimed at professional avian biologists and ornithologists as well as graduate students of avian ecology, evolution and conservation. It also appeals to a more general audience of invasion ecologists.

When seen hunting over a meadow, barn owls have an ethereal grace and beauty that can be matched by no other bird. The barn owl has an almost global distribution and has lived in close proximity to humans since settlement and farming created the forest clearings needed for hunting and places in which to nest. However, in many countries, barn owl numbers are falling rapidly. This book explores the relationships between barn owls and their prey worldwide, and demonstrates how an understanding of such relationships can help in the conservation of the species. In this comprehensive account, Iain Taylor describes the biology and ecology of this species, including the factors affecting breeding success, and causes of mortality affecting the final recruitment of new birds into the population. He concludes by suggesting ways in which we can manage and conserve this beautiful bird for the future.

Woodlands offer birds an extremely wide range of habitats. In this book, the variation in bird life in woodlands, and the factors that influence bird numbers and distributions are examined. What birds are found in which habitats? What effect does forestry and woodland management have? How can we enhance bird populations by habitat management? Are bird numbers and distributions in natural and managed forests different - and if so, why? The gamut of British woodland is covered, from ancient coppice and wood-pasture in the lowlands, to recently-planted conifer forests in the uplands, and comparisons are drawn with mainland Europe and North America. The book discusses the effects of factors such as increased deer numbers, air-pollution and new wood creation on lowland farms, all of which are changing the face of our woodlands today. This book is a must for all those interested in woodlands, and the birds which live in them.

Despite the scale of change in agricultural methods in the late eighteenth and nineteenth centuries, farmland birds were little affected, with many benefiting from the appearance of extensive new resources. This book is an historical account of the impact of changes in farming methods on the bird populations of British farmland over the past 250 years. A comparison with modern experience shows significant differences, with the more recent changes in grassland management, herbicide use and harvesting methods leading to a loss of diversity in farmland and, consequently, resulting in steep declines in bird numbers.

Vertebrate Life distills the necessary information from vertebrate anatomy, physiology, ecology, and behavioral studies and then helps students see important connections across levels of biological scale. The result is students come to understand how organisms function effectively in their environments and how lineages of organisms change through evolutionary time. Processing complex detailed information about expansive phylogenies and diverse anatomies can be difficult for even the most motivated students, and Vertebrate Life addresses this challenge by combining appropriately-detailed, clearly-written text with outstanding phylogenies and figures, making it a thorough and engaging reference for students and instructors alike. The text's impressive illustration program helps students visualize complex concepts, allowing them to parse difficult anatomical information. The 11th edition will have an upgraded illustration program with several new and revised figures, including layered figures presented in the new enhanced eBook.

In this definitive work, Ernest Glen Wever establishes the evolutionary importance of the reptile ear as the origin of the higher type of auditory apparatus shared by man and the mammals. Tracing the development of the auditory receptor in the living reptiles, he examines the use of a variety of mechanisms and principles of action by that receptor. While some of the material in this book has appeared previously in journal articles, most of it is presented here for the first time. Basing this study on his twenty years of research at Princeton's Auditory Research Laboratories, Professor Wever treats in anatomical and functional detail the auditory mechanism in about 250 species and subspecies of reptiles. The anatomical treatment rests on dissections and histological examinations of the ears in serial section, and portrays the relevant features in drawings that represent particular views of reconstructions. The author evaluates the performance of thesse ears electrophysiologically, in terms of the electrical potentials of the cochlea, paying particular attention to problems of the transmission of vibrations inward to the cochlea and the actions there in stimulating the sensory cells. Professor Wever finds that the cochlea emerged independently from the non-auditory labyrinth in three different vertebrate groups: fishes, amphibians, and reptiles. It was among the reptiles, however, that the vertebrate ear took on a more advanced configuration from which it further evolved along separate lineages in the birds and mammals. Ernest Glen Wever is Eugene Higgins Professor of Psychology Emeritus at Princeton University. Originally published in 1978. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

Many of us have experienced the interruption, pleasant or otherwise, of a bird singing from high in the trees or a lone chirper perched outside a bedroom window and wondered what the song was about. Following a world expert on birdsong from the woods of Martha's Vineyard to the tropical forests of Central America, Don Staop brings to life the quest to unravel this ancient mystery: Why do birds sing and what do their songs really mean? In this creative mixture of reportage, storytelling, and research, Stap distills the complexities of the study of birdsong and unveils a remarkable discovery that sheds light on the mystery of mysteries: why young birds in the suborder oscines--the "true" songbirds--must learn their songs while closely related birds are born with their songs genetically encoded. As the story unfolds, Stap contemplates our enduring fascination with birdsong, from ancient pictographs and early Greek soothsayers to the story of Mozart's pet starling. He identifies birds by their specific sounds and calls, and explains the true function of a bird's song, from mating calls to claims of territory. In a modern, noisy world, it is increasingly difficult to hear the sounds of nature around us. Exploring birdsong takes us to that rare place--in danger of disappearing forever--where one hears only the planet's oldest music.

This book explores the factors affecting the survival of small populations. As the human impact on Earth expands, populations of many wild species are being squeezed into smaller and smaller habitats. As a consequence, they face an increasing threat of extinction. National and international conservation groups rush to add these populations, species and sub-species to their existing endangered and threatened lists. In nations with strong conservation laws, listing often triggers elaborate plans to rescue declining populations and restore their habitats. The authors review these theoretical ideas, the existing data, and explore the question: how well do small and isolated populations actually perform? Their case study group is the song sparrows of Mandarte Island, British Columbia. This population is small enough and isolated enough so that all individuals can be uniquely marked and their survival and reproduction monitored over many generations. This is one of the strongest long-term ecological studies of a contained vertebrate population, now in its 31st year.

A fascinating and important work of ornithology, which led E.O. Wilson to call it "one of the most interesting discoveries I've seen in animal sociobiology in years," "Ravens In Winter" is a scientist's impassioned study to understand the mysterious social habits of one of nature's most formidable birds, the raven.
Why do ravens, generally understood to be solitary creatures, share food between each other during winter? This was the question Bernd Heinrich asked himself as he was observing another one of his prime research subjects, the highly social bumblebee. And it was during these trips to Maine, the site of much of his research, where he first noticed this "unusual" behavior of ravens. From an evolutionary perspective, the raven's willingness to share food challenged conventional wisdom. There was no biological imperative, it seemed, to their communal spirit. The more Heinrich observed their habits, the more odd the bird's behavior became. What started as mere curiosity turned into an impassioned research project, and "Ravens In Winter," the first research of its kind, explores the fascinating biological puzzle of the raven's rather unconventional social habits.

Along with reproduction, balancing energy expenditure with the limits of resource acquisition is essential for both a species and a population to survive. But energy is a limited resource, as we know well, so birds and mammals - the most energy-intensive fauna on the planet - must reduce energy expenditures to maintain this balance, some taking small steps, and others extreme measures. Here Brian K. McNab draws on his over sixty years in the field to provide a comprehensive account of the energetics of birds and mammals, one fully integrated with their natural history. McNab begins with an overview of thermal rates - much of our own energy is spent maintaining our 98.6[degrees]F temperature - and explains how the basal rate of metabolism drives energy use, especially in extreme environments. He then explores those variables that interact with the basal rate of metabolism, like body size and scale and environment, highlighting their influence on behavior, distribution, and even reproductive output. Successive chapters take up energy and population dynamics and evolution. A critical central theme that runs through the book is how the energetic needs of birds and mammals come up against rapid environmental change and how this is hastening the pace of extinction.
