The phenomenon of bird migration has fascinated people from time immemorial. The arrivals and departures of different species marked the seasons, heralding spring and autumn and providing a reliable calendar long before anything better became available. Migration is shown by many kinds of animals, including butterflies and other insects, mammals, marine turtles, and fish, but in none is it as extensively developed as in birds. The collective travel routes of birds span almost the entire globe, with some extreme return journeys covering nearly 20,000 miles. As a result of migration, bird distributions are continually changing—in regular seasonal patterns as well as on local, regional, or global scales. Migration has repeatedly prompted familiar questions, such as where birds go or come from, why they do it, how they know when and where to travel, and how they find their way. In this seminal new book, Ian Newton sets out to answer these questions and more. The book is divided into four main sections: the first is introductory, describing the different types of bird movements, methods of study, and the main migration patterns seen around the British Isles. The second part is concerned mainly with the process of migration—the timing, energy needs, weather effects, and navigation. The third covers evolution and change in migratory behavior, and the fourth examines the geographical and ecological aspects of bird movements.

In the latest addition to the New Naturalist series, Ian Newton explores bird populations and what causes their fluctuation – food supplies, competitors, predators, parasites, pathogens and human activity.
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 massive changes in land use in recent decades than at any previous comparable period. These developments have in turn brought huge changes in bird habitats and populations; some species dependent on the old landscapes declined, while others have increased. Over the same period, changing public attitudes to wildlife 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 as they are, and changed over the years in the way that they have. The regular watching and study of birds now provides a source of recreation and pleasure for very large numbers of people, while continued monitoring of bird numbers can also alert us to impending environmental problems. For all of us, a world with fewer birds would be a poorer place.

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.

Given the underlying topography, the scenery over most of Britain has been created largely by human activities. Over the centuries, landscapes have been continually modified as human needs and desires have changed.                      Each major change in land use has brought changes to the native plants and animals, continually altering the distribution and abundance of species. This is apparent from the changes in vegetation and animal populations that were documented in historical times, but even more so in those that have occurred since the Second World War.           More than seventy per cent of Britain's land surface is currently used for crop or livestock production, and in recent decades farming has experienced a major revolution. Not only has it become more thoroughly mechanised, it has also become heavily dependent on synthetic fertilisers and pesticides, and increasingly large-scale in its operation. These changes have brought crop yields and livestock production to levels previously considered unattainable. However, such high yields have been achieved only at huge financial and environmental costs. One of the most conspicuous, and best documented, consequences of modern agriculture has been a massive loss of wildlife, including birds.           In this timely addition to the New Naturalist Library, Ian Newton discusses the changes that have occurred in British agriculture over the past seventy years, and the effects they have had on bird populations. He explains how different farming procedures have affected birds and other wildlife, and how an understanding of the processes involved could help in future conservation.

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.
