<p>After habitat loss, the impact of naturalized exotics is the single most important cause of extinction in native species throughout the world. In this book, updated from the first edition in 1987, Christopher Lever describes when, where, how and by whom the world's naturalized birds were introduced to places outside their natural range, and discusses the economic and ecological impacts each has had in its naturalized regions.</p>

Almost two hundred species of birds have become extinct in the past 400 years, and a similar number today are in imminent danger of following them. The world's conservationists are leading the fight to prevent the demise of these remaining critically endangered birds, with a fair degree of success. This new book examines the process and issues concerning extinction - how and why it happens and what can be done about it. Whilst man is to blame for many of the causes, such as persecution and habitat loss, species have become extinct on a regular basis since life began. After several thought-provoking introductory chapters, the book showcases about 20 species on the brink of extinction from around the world and describes the work that is being undertaken to save them. Some are success stories, but a few are not. This is a subject close to the hearts of all birders and ornithologists and this book, written by a team of leading conservationists, will strike a chord in most of them.

Facing Extinction: The World's Rarest Birds and the Race to Save Them

Between 1980 and 2004, more than 70 bird species - vagrants from Central Asia, Siberia and North America - have been added to the British list. This book is a compilation of all those records, with accounts of finding a 'First for Britain' interspersed with 25 annual summaries of the birding years 1980-2004 and 25 essays by prominent birders about their special years during this period. The book is illustrated with colour photographs and black and white artworks. Foreword by Eric Meek.

An acknowledged classic of narrative nature-writing, Donald Watson's The Hen Harrier was the culmination of a lifetime's study of this beautiful upland bird. A gentle, warm and wonderfully written book, The Hen Harrier stems from an age of 'amateur' conservation, from the pen of a man who cared deeply about birds and their habitats, especially of the Scottish borders where he conducted much of his research and painting. The book was among the last of a dying breed; it would be thirty years or more before writing on our natural history would again reach the heights of accessibility to nature-lovers exemplified by Donald Watson and his peers. The book starts with Watson setting down more or less everything known about harriers – which at that time often consisted of information sent by letter to the author, rather than published in a journal – before moving on to the story of Watson's years studying nests in the south-west of Scotland.With a foreword by conservation champion Mark Avery, this edition of Watson's greatest work is particularly timely. The conflict between grouse-shooting interests, which has overseen the virtual extinction of the harrier as a breeding bird in England through illegal persecution, and an increasingly vocal conservationist lobby is the number one conservation issue in Britain today.Donald Watson's narrative soars like a sky-dancing harrier throughout this book. Read it, and be taken back to a simpler age of nature conservation by a true master of the art.

No major changes were needed for this second edition, but the opportunity has been taken to correct some minor errors and to augment the bibliography. Crispin Fisher has also provided three new drawings.As before, the book's emphasis is on the effects of weather on bird life and the meteorological aspects of the avian environment rather than long-term climatic influences, though the latter are not ignored.The chapter titles indicate the book's range and interest: The Weather; Flight; Feeding; Aerial Feeding; Breeding; Comfort; Migration; Migrational Drift and Displacement; Vagrancy; Migration of Soaring Birds; Extreme Weather; Seabirds. From such themes the author, a professional meteorologist, has composed an intriguing and instructive study (and an introduction to meteorology) of exceptional usefulness to birdwatchers and ornithologists.Crispin Fisher contributes 35 line illustrations and there is a 16-page section of photographs.See the back flap of this book jacket for some reviews of the first edition.
