Book Description
Dr Newton is now a senior ornithologist with the Natural Environment Research Council and the book draws on his wide knowledge of the Sparrowhawk, as well as that of other workers in Britain and abroad. The text gives a detailed account of all aspects of the Sparrowhawk's lifestyle, population levels and trends, and the impact of man and environment on the species in recent times. The book also has the benefit of Dr Newton's particular interest in population regulation and breeding performance, and in the remarkable contrast in size between the Sparrowhawk sexes (males being half the weight of females), which means that they diverge, almost as separate species, in habitat preference, diet and in response to circumstance. The narrative is fully supported by diagrams, tables and photographs, and is embellished by Keith Brockie's evocative and accomplished drawings.

Book Description
Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.

Book Description
Britain is home to fifteen species of breeding birds of prey, from the hedgerow-hopping Sparrowhawk to the breathtaking White-tailed Eagle. In this handsomely illustrated book, acclaimed British filmmaker and naturalist David Cobham offers unique and deeply personal insights into Britain's birds of prey and how they are faring today. He delves into the history of these magnificent birds and talks in depth with the scientists and conservationists who are striving to safeguard them. In doing so, he profiles the writers, poets and filmmakers who have done so much to change the public's perception of birds of prey. There are success stories—five birds of prey that were extinct have become reestablished with viable populations—but persecution is still rife. Featuring drawings by famed wildlife artist Bruce Pearson, this book reveals why we must cherish and celebrate our birds of prey, and why we neglect them at our peril.

Book Description
A large and spectacular bird of prey, the Goshawk lives in boreal forests throughout the Northern hemisphere. The Goshawk is an authoritative yet highly readable monograph of the species. A powerful hunter of large birds and woodland mammals, it was persecuted for many years by game keepers to the point of extinction in the UK. However, escaped falconry birds led to the establishment of a new population in the 1960s, though the species remains rare and elusive - birders need a combination of hard work and a little luck to see this magnificent raptor. The Goshawk includes chapters on nomenclature, races and morphs, biometrics, nesting, incubation and chick-rearing, migration, feeding ecology, population dynamics, and conservation, punctuated throughout with illuminating tales from author Robert Kenward's extensive field research. The book is packed with illustrations, figures and maps, and contains a selection of the author's superb photographs of the birds. The product of almost 30 years work, this title is a classic Poyser monograph; birders will enjoy the fascinating insights into the biology of the bird, while academics will appreciate the book's comprehensive literature review.

Book Description
A superb success as a bird, combining great speed, aeronautical grace, and fearlessness...inhabitant of wild places, inaccessible cliffs, and skyscrapers...worldwide dweller, trans-equatorial migrant, and docile captive—the peregrine falcon stands alone among all others of its kind. Perhaps this is why so many varied people rushed to its aid when it faced decimation by pesticide poisoning. In this personal and highly entertaining memoir, Jim Enderson tells stories of a lifetime spent studying, training, breeding, and simply enjoying peregrine falcons. He recalls how his boyhood interest in raptors grew into an ornithological career in which he became one of the leading experts who helped identity DDT as the cause of the peregrine falcon's sudden and massive decline across the United States. His stories reveal both the dedication that he and fellow researchers brought to the task of studying and restoring the peregrine and the hair-raising adventures that sometimes befell them along the way. Enderson also seamlessly weaves in the biology and natural history of the peregrine, as well as anecdotes about its traditional and widespread use in falconry as an aggressive yet tractable hunter, to offer a broad portrait of this splendid and intriguing falcon.
