    The Eagle Owl is one of the largest owls in the world, and is considered the most eclectic in terms of habitat, nest site and diet. An undisputed top predator, it can prey on a range of mammals up to the size of a fox, and almost every species of bird, reptile, amphibian and fish, as well as a wide spectrum of invertebrates. Surprisingly, this owl can breed almost anywhere, the female laying her eggs on a variety of natural and artificial structures over an array of altitudes. Despite being so adaptable, however, it is still a vulnerable species, and has suffered widely from persecution as well as other threats including electrocution on power lines, decreasing prey availability, the effects of pesticides and pollutants, and habitat alteration. Vincenzo Penteriani and María del Mar Delgado have studied this fascinating bird extensively across its vast Eurasian range. In this book, they detail its intriguing ecology, covering distribution, foraging and breeding behavior, interspecific interactions, dispersal and conservation issues. The final two chapters provide a remarkable insight into vocal and visual communication. Scientists have long believed that owls and other crepuscular and nocturnal birds forgo the visual signals found in other avian species, but recent research on the Eagle Owl has suggested otherwise.Bringing together more than 30 years of research, The Eagle Owl tells a story rich in detail of one of the most thrilling and magnificent birds in the world.

  • - A History of the Exploitation of Wild Birds
    av Michael Shrubb
    931,-

    The way wild birds have been exploited over the centuries forms the focus of this remarkable new book by Michael Shrubb. It looks at the use of birds as food, for feathers and skins, for eggs, as cage birds, as specimens and for hunting, focusing on Britain, northern Europe and the North Atlantic. Never before has a book brought the huge amount of information on these topics in the academic literature together under one cover.Introductory chapters on what was taken, when, why and its impact are followed by a number of sections looking in detail at important bird groups. Along with discussions of broader themes of exploitation, the book is packed with amazing facts. For example, we learn ΓÇó why Grey Herons were so important in medieval falconryΓÇó why the Black Death was good news for bustardsΓÇó why Napoleon is to blame for the scarcity of Quail in Britain todayΓÇó when tame plover stew was all the rageThe book concludes with discussions of the cage bird and plumage trades, both now consigned to the annals of history, in Britain at any rate. As well as summarising and condensing the material into a readable and entertaining account, Shrubb goes back to the original sources. This has allowed him to shed new and surprising light on the biogeography of a number of British birds.

    The Snowy Owl - possibly the world''s sexiest bird - needs little introduction. This massive white owl breeds throughout the Arctic, wherever there are voles or lemmings to hunt, from Scandinavia through northern Russia to Canada and Greenland. Southerly movements in winter see North American birds travel as far south as the northern United States, while infrequent vagrants on the Shetlands and other northern isles are a magnet for birders. The Snowy Owl gives this popular bird the full Poyser treatment, with sections looking at morphology, distribution, palaeontology and evolution, habitat, breeding, diet, population dynamics, movements, interspecific relationships and conservation, supported by some fabulous photography and the art of Jackie Garner. A major strength is the availability to the authors of Russian literature, which is generally out of reach for Western scientists.

    A common sight around the more northerly shores of the British Isles, the Common Eider is the largest duck in the northern hemisphere. The eider is particularly well adapted to cold-water environments; the insulating properties of eider down are iconic. The species is taxonomically interesting, with a range of well-marked subspecies reflecting the patterns of ice coverage during ancient glaciations, and these ducks have also provided the focus for a number of important behavioral studies, especially on feeding ecology and energy budgets.Eiders have a long association with humans, and have deep cultural significance in many societies. However, modern lifestyles are exposing these ducks to a wide range of new pressures.This monograph provides a comprehensive portrait of the Common Eider; authors Chris Waltho and John Coulson bring together an extensive and diverse international literature, with sections on taxonomy, habitats, breeding biology, population dynamics, diet and foraging, dispersal and migration, and conservation.

    For its size, Kenya probably has the most diverse range of habitats of any country in Africa, if not the world. Within its borders there are alpine peaks, montane forests, high plateaux, savannas, lowland forests, coastal woodlands and wetlands, and a string of varied lakes in the Great Rift Valley. The range of wildlife to be found in the region is correspondingly diverse. this book explores the wildlife and habitats in great detail and gives a thorough overview of Kenya''s natural history.
