The purpose of this document is to provide an information base on the effects of aircraft noise and sonic booms on various animal species. Such information is necessary to assess potential impacts to wildlife populations from proposed military and other flight operations. To develop this document the National Ecology Center conducted a literature search of information pertaining to animals and wildlife. Information concerning other types of noise was also gathered to supplement the lack of knowledge on the effects of aircraft noise. The bibliographic abstracts in this report provide a compilation of current knowledge. No attempt was made to evaluate the appropriateness or adequacy of the scientific approach of each study. (sdw).

This 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.
