Earlier naturalists formed the impression that bird numbers remained more or less stable through time. In the years since these words were written, however, changes have occurred in the landscapes of the British Isles and in the seas around our coasts, causing bird populations to fluctuate in an unprecedented way.In Ian Newton’s latest New Naturalist volume, he explores bird populations and why their numbers vary in the way they do, from year to year or from place to place. He addresses the various factors that we know limit bird numbers – food supplies and other resources, competitors, predators, parasites and pathogens, and various human impacts.The combination of a rapidly expanding human population, a predominantly utilitarian attitude to land, central government policy on land use, and increasing mechanisation have combined to promote more massive changes in land use – and hence in bird habitats – in recent decades than at any comparable period previously. These developments have in turn brought huge changes in bird populations, as some species dependent on the old landscapes declined, and others benefiting from the changes increased. Over the same period, changing public attitudes to wildlife, protective legislation and a growing network of nature reserves allowed previously scarce bird species to recover from past onslaughts, while climate warming has promoted further changes.In this seminal new work, Ian Newton sets out to explain why different bird species are distributed in the numbers that they are, and have changed over the years in the way that they have. He emphasises the factors that influence bird numbers, rather than the numbers themselves, thus providing a much-needed overview which is necessary if we are to successfully manage bird populations, whether for conservation reasons, for sustainable hunting or for crop protection. The continued monitoring of bird numbers can also alert us to impending environmental problems. In addition, the regular watching and study of birds now provides a source of recreation and pleasure for very large numbers of people, who would find a world with fewer birds a poorer place.

Ian Newton, author of Farming and Birds and Bird Migration returns to the New Naturalist series with a long awaited look at the uplands and its birds.The uplands of Britain are unique landscapes created by grazing animals, primarily livestock. The soils and blanket bogs of the uplands are also the largest stores of carbon in the UK, and 70% of the country’s drinking water comes from the uplands. It’s a significant region, not least to the multitudes of bird species that hunt, forage and nest there.Once again, Ian Newton demonstrates his mastery of the subject matter at hand, in this beautifully illustrated, authoritative addition to the New Naturalist series.

This book meets the demand for a comprehensive introduction to understanding the processes of population limitation. Recognized world-wide as a respected biologist and communicator, Dr. Ian Newton has now written a clear and detailed treatise on local scale population limiting factors in birds. It is based almost entirely on results from field studies, though it is set in a contemporary theoretical framework. The 16 chapters fall under three major section headings: Behavior and Density Regulation; Natural Limiting Factors; and Human Impacts. Population Limitation in Birds serves as a needed resource expanding on Dr. David Lacks research in this area of ornithology in the 1950s. It includes numerous line diagrams and beautiful illustrations by acclaimed wildlife artist Keith Brockie. Provides a sorely needed introduction to a long-established core subject in ornithology Focuses on local scale factors Written by a well-known biologist and effective communicator Includes numerous line diagrams and beautiful illustrations by acclaimed wildlife artist Keith Brockie

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

This book should be of value to anyone interested in bird evolution and taxonomy, biogeography, distributional history, dispersal and migration patterns. It provides an up-to-date synthesis of current knowledge on species formation, and the factors influencing current distribution patterns. It draws heavily on new information on Earth history, including past glacial and other climatic changes, on new developments in molecular biology and palaeontology, and on recent studies of bird distribution and migration patterns, to produce a coherent account of the factors that have influenced bird species diversity and distribution patterns worldwide.Received the Best Bird Book of the Year award for 2004 from British Birds magazine.* Winner of the British Birds/British Trust for Ornithology, Bird Book of the Year 2004!* The first book to deal comprehensively with bird speciation and biogeography* Up-to-date synthesis of new information* Clearly written* No previous book covers the same ground* Many maps and diagrams* Makes difficult and widely scattered information accessible and easily understood* A sound base for future research* Takes full account of recent developments in molecular biology

The Migration Ecology of Birds, Second Edition covers all aspects of this absorbing subject, including migratory processes, problems of navigation and vagrancy, timing and physiological control of migration, large-scale movement patterns, the effects of recent climate change, the problems that migrants face, and the factors that limit their populations. This book provides a thorough and in-depth review of the state of the science, with the text supplemented by abundant tables, maps and diagrams. Written by a world-renowned avian ecology and migration researcher, this book reveals the extraordinary adaptability of birds to the variable and changing conditions across the globe.

This book represents the most updated and detailed review of bird migration, its evolution, ecology and bird physiology. Written in a clear and readable style, it will appeal not only to migration researchers in the field and ornithologists, but to anyone with an interest in this fascinating subject.

Features updated and trending ecological aspects, including various types of bird movements, dispersal and nomadism, and how they relate to food supplies and other external conditions Contains numerous tables, maps, diagrams, a glossary, and a bibliography of more than 3,000 up-to-date references Written by an active researcher with a distinguished career in avian ecology, including migration research

The aim of this book is to outline the main methods and techniques available to ornithologists. A general shortage of information about available techniques is greatly hindering progress in avian ecology and conservation. Currently this sort of information is disparate and difficult to locate with much of it widely dispersed in books, journals and grey literature. Sutherland and his editorial team bring together in a single authoritative source all the ornithological techniques the avian community will ever need. For use by graduate students, researchers and practising conservationists worldwide. Bird Ecology and Conservation is the first title in a new series of practical handbooks which include titles focusing on specific taxonomic groups as well as those describing broader themes and subjects. The series editor is William J Sutherland.
