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.
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.
