Raptor Research and Management Techniques


Book Description

« Think about how we know about past events in human history (e.g., the expansion of the Roman Empire, or the American Revolution). What types of records document those events? Now think about Earth's history, specifically the past environmental or climatic conditions at times before recorded human history. What records might there be of such conditions? Make a list of your ideas. n assemblage of five major types of natural archives of Earth's environmental and climatic history. What common feature(s) do each of these paleoclimate archives share? an assemblage of 5 major types of natural records, or archives, of Earth's environmental and climatic history. Just like a diary or other historical document, the layers in these natural archives contain indirect evidence (i.e., proxies) about past conditions and events, recorded in a sequential order. The evidence is specific to a certain time period and may be general or very detailed, depending on the rate that information was recorded. The faster the rate at which the recorder grew (trees and corals), accumulated (snow and ice), or was deposited (sedimentary sequences), the more detailed the record is, and the higher its resolution. For example, a record in which an annual signal can observed has a very high resolution. In contrast, if the finest observable details are on the order of a million years, then that record would have a low resolution. »--




The Common Buzzard


Book Description

'Based on many years of personal research, and a thorough knowledge of the European literature, the authors provide an eminently readable account of the biology of the Common Buzzard. Whatever your interests in birds, I can recommend this book for its content of information and insight.' – Professor Ian Newton OBE, FRS, FRSE Soaring majestically on thermals with broad wings raised, the Common Buzzard is a familiar sight for many people across Eurasia. In fact, thanks to a remarkable ability to adapt to local conditions, it is now one of the most abundant hawks in the world. The Common Buzzard can exploit a variety of nest sites, and has an eclectic diet that ranges from earthworms and voles to woodpigeons and even deer carcasses. This is a species rich in paradoxes. Why does a hawk evolved for hunting small mammals thrive on invertebrates and carrion? How can a raptor renowned for dramatic territorial displays occur at such high densities? And why does such a large bird that can travel long distances spend so much time in small areas? Sean Walls and Robert Kenward delve deep into the ecology of the Common Buzzard to provide answers to these questions and many more, as well as examining the conservation conundrums raised by this bird. Bringing together a wealth of research on the species' origins, feeding behaviour and breeding, along with information on movement and survival from the authors' own studies, The Common Buzzard provides an invaluable insight into exactly what has enabled this marvellous raptor to return to old haunts to impress, inspire and connect people with nature.

The Snowy Owl


Book Description

A comprehensive monograph of the beautiful Snowy Owl, famed for its elegant, all-white plumage. The Snowy Owl 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 on morphology, distribution, palaeontology and evolution, habitat, breeding, diet, population dynamics, movements, interspecific relationships and conservation, supported by some fabulous photography. The award-winning author team also had access to Russian research literature, which is generally out of reach for Western scientists.
