Book Description
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.
The Birds of South America

Book Description
A land of incredible natural resources, the South American continent is rich in plant and animal species. Among birds alone, over 3,100 species are either resident or migrant. Birds are some of South America's treasures and also one of its most endangered resources. Hence the need for a descriptive record of South American birds that will serve both professional and amateur bird students and encourage conservation of these magnificent species. Although South American birds elicit much popular and scientific interest, they have never been completely or satisfactorily described and cataloged in a single, published source. The Birds of South America, projected to be a four-volume work, thus fills a critical void. Starting from a museum approach, the authors have examined specimens of each subspecies, comparing them visually and trying to discern the patterns in their plumage variation, both intra- and inter-specifically. They take a new look at bird systematics, reassessing relationships in light of new information. Perhaps most important, they combine this review and analysis with extensive field observations to give an accurate, incisive portrait of the birds in nature. At a time when rapid development is devastating millions of acres of tropical habitat in South America, this record of an endangered resource becomes crucial. If the birds and other plants and animals of South America are to be saved, they must first be known and appreciated. The Birds of South America is a major step in that direction. Volume II includes the Ovenbirds and Woodcreepers, Antbirds, Gnatcatchers, and Tapaculos; Tyrant Flycatchers; and Manakins and Cotingas. The remaining volumes of The Birds of South America will be: Volume III: The Nonpasserines (Landbirds) Volume IV: The Nonpasserines (Waterbirds) No release date has been set for the remaining volumes.
