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 Just like a diary or other historical document, the layers in these natural archives contain indirect evidence (i.e., proxies) about past conditions and events, recorded in a sequential order.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. »--

Book Description
A fascinating look at one of the greatest conservation success stories of the modern era: the wildly popular, unique, and thrilling raptor, the Osprey. Ospreys are one of the few bird species that are found throughout the world. From forests in Hokkaido to rivers in Oregon and islands off Australia, Ospreys steal the show as nature lovers easily watch them build their massive nests and tend to their young. The fact that the Osprey is one of the few large birds that can hover adds to its mystique, and to watch it plunge into the water, emerging with a fish clutched in its talons, is truly a sight one will remember. As widespread as Ospreys are, not long ago they were under threat of extinction. During the 1950s and '60s, scientists tied the decline of Osprey populations to the heavy use of DDT and other human pollutants. In the 1980s, Ospreys began a slow recovery due to the efforts of conservationists and through the resilience of the adaptable raptors themselves. Today they are again considered common in most parts of the world, although some populations remain threatened. In this gorgeously illustrated book, Alan F. Poole, one of America's premier Osprey experts, has written a lyrical exposé of these majestic creatures, describing their daily habits and exploring their relationship with the environment. Ospreys celebrates the species' miraculous recovery from contaminants and hunters, chronicles their spectacular long-distance migrations, and unveils their vital role in bringing life to coastal habitats. Few other birds have such a hold on the human imagination. This book shows us why.

Book Description
Raptors are an unusual success story of wildness thriving in the heart of our cities—they have developed substantial populations around the world in recent decades. But there are deeper issues around how these birds make their urban homes. New research provides insight into the role of raptors as vital members of the urban ecosystem and future opportunities for protection, management, and environmental education. A cutting-edge synthesis of over two decades of scientific research, Urban Raptors is the first book to offer a complete overview of urban ecosystems in the context of bird-of-prey ecology and conservation. This comprehensive volume examines urban environments, explains why some species adapt to urban areas but others do not, and introduces modern research tools to help in the study of urban raptors. It also delves into climate change adaptation, human-wildlife conflict, and the unique risks birds of prey face in urban areas before concluding with real-world wildlife management case studies and suggestions for future research and conservation efforts. Boal and Dykstra have compiled the go-to single source of information on urban birds of prey. Among researchers, urban green space planners, wildlife management agencies, birders, and informed citizens alike, Urban Raptors will foster a greater understanding of birds of prey and an increased willingness to accommodate them as important members, not intruders, of our cities.

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.

Book Description
Until recently, surprisingly little has been known about the biology and behavior of tropical forest raptors, including such basic aspects as diets, breeding biology, habitat requirements, and population ecology, information critical to the development of conservation efforts. The Peregrine Fund conducted a significant eight-year-long research program on the raptor species, including owls, in Tikal National Park in Guatemala to learn more about Neotropical birds of prey. Impressive and unprecedented in scale, this pioneering research also involved the development of new methods for detecting, enumerating, and studying these magnificent but often elusive birds in their forest home. Beautifully illustrated with photographs of previously little-known species, the resulting book is the most important single source for information on the lowland tropical forest raptor species found in Central America.Neotropical Birds of Prey covers twenty specific species in depth, including the Ornate Hawk-Eagle, the Barred Forest-Falcon, the Bat Falcon, and the Mexican Wood Owl, offering thorough synopses of all current knowledge regarding breeding biology and behavior, diet, habitat use, and spatial needs. Contributors to this landmark work also show how the populations fit together as a community with overlapping habitat and prey needs that can put them in competition with reptiles and mammalian carnivores as well, yet differ from one another in their nesting or feeding behaviors and population dynamics. The work's substantive original data offer interesting comparisons between tropical and temperate zone species, and provide a basis for establishing conservation measures based on firsthand research. Making available for the first time new data on the biology, ecology, behavior, and conservation of the majestic owls and raptors of the New World tropics, this book will appeal to a wide ornithological readership, especially the many raptor enthusiasts around the world.

Book Description
Are you curious about the remains of an animal you have found? This compilation of the most likely found body parts of animals eaten by raptors will help you identify your discovery. Including over 100 species of bird and mammal prey of raptors such as sparrowhawks, peregrines and hen harriers, this photographic guide highlights the common feathers, fur and other body parts found at raptor nests, roosts, plucking posts and other opportunistic spots. Discovering what raptors eat is an important part of confirming their feeding ecology and how this might change over time, vary on a local level or in response to changing prey populations, as well as dispelling myths and assumptions about what certain raptor species eat. Diet studies are vital for the conservation of raptor species; the more we know about what they need for survival the more we can predict and plan long-term for the protection and survival of raptors that may be vulnerable and in decline. This is the first book to show in detail the actual parts of a bird, mammal or other animal that you are likely to find in a garden, woodland or beneath a raptor roost. As more people take an interest in raptors and watch species such as peregrines via webcams and through watch groups, there is greater opportunity for finding prey remains. This book provides the first and most important step in identifying a prey species.
