DOWNLOAD EBOOKThis book examines the current literature and knowledge on the evolution and ecology of all the birds named as eagles, with particular emphasis on the larger species. It also examines the past and current relations between eagles and people, including habitat change and conservation issues. Eagle ecologies and conservation are currently seriously impacted by human activities such as industrialization, urbanization, pollution, deforestation and hunting. Some eagle species have consequently experienced extreme population changes. There are, however, some positive developments. Eagles have a strong, historic bond with human civilization, due to their status as the world’s most charismatic birds. Conservation policies have also been successful in repopulating some ecosystems with breeding eagles. Therefore, despite the complexity of this relationship, there may yet be hope for this unique species group, frequently rated as the kings of birds, and symbolic of human power, ambition, royalty, nationality, and even concepts of God. It is hoped that this book will contribute to the further understanding of these unique and fantastic birds.

DOWNLOAD EBOOKBald eagles (Haliaeetus leucocephalus) associate with wintering waterfowl concentrations throughout the United States, but little detailed information is available on eagle-waterfowl relations. This report concerns the ecology of bald eagles wintering in the vicinity of Swan Lake National Wildlife Referenc in north-central Missouri and, more specifically, examines the association of the eagles with waterfowl during the winters of 1975-76, 1976-77, and 1977-78

DOWNLOAD EBOOKPrato and Fagre offer the first systematic, multi-disciplinary assessment of the challenges involved in managing the Crown of the Continent Ecosystem (CCE), an area of the Rocky Mountains that includes northwestern Montana, southwestern Alberta, and southeastern British Columbia. The spectacular landscapes, extensive recreational options, and broad employment opportunities of the CCE have made it one of the fastest growing regions in the United States and Canada, and have lead to a shift in its economic base from extractive resources to service-oriented recreation and tourism industries. In the process, however, the amenities and attributes that draw people to this 'New West' are under threat. Pastoral scenes are disappearing as agricultural lands and other open spaces are converted to residential uses, biodiversity is endangered by the fragmentation of fish and wildlife habitats, and many areas are experiencing a decline in air and water quality. Sustaining Rocky Mountain Landscapes provides a scientific basis for communities to develop policies for managing the growth and economic transformation of the CCE without sacrificing the quality of life and environment for which the land is renowned. The book begins with a natural and economic history of the CCE. It follows with an assessment of current physical and biological conditions in the CCE. The contributors then explore how social, economic, demographic, and environmental forces are transforming ecosystem structure and function. They consider ecosystem change in response to changing patterns of land use, pollution, and drought; the increasing risk of wildfire to wildlife and to human life and property; and the implications of global climate change on the CCE. A final, policy-focused section of the book looks at transboundary issues in ecosystem management and evaluates the potential of community-based and adaptive approaches in ecosystem management.

Bildstein has studied migrating raptors on four continents and directs the conservation science program at Hawk Mountain Sanctuary, Pennsylvania, the world's first refuge for migratory birds of prey. In this book, he details the stories and successes of twelve of the world's most important raptor-viewing spots, among them Cape May Point, New Jersey; Veracruz, Mexico; Kekoldi, Costa Rica; the Strait of Gibralter, Spain; and Elat, Israel."--BOOK JACKET.
