Owls are enduringly popular birds, but due to their nocturnal habits most species are difficult to see well. The plumages of many species are cryptic and difficult to separate by plumage alone. This problem is compounded by the different morphs that many adopt. This book fully describes every known species and subspecies of owl, as well as presenting the latest evidence on owl taxonomy, based on DNA work and vocalisations. Because voice is vital in owl identification, much emphasis is placed on it in the book and sonograms are provided for many species. A CD of owl vocalisations will accompany the book.

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 I includes the Jays and Swallows; Wrens, Thrushes, and Allies; Vireos and Wood-warblers; Tanagers, Icterids, and Finches. 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.

This groundbreaking volume is the first comprehensive, critical examination of the rise of protected areas and their current social and economic position in our world. It examines the social impacts of protected areas, the conflicts that surround them, the alternatives to them and the conceptual categories they impose. The book explores key debates on devolution, participation and democracy; the role and uniqueness of indigenous peoples and other local communities; institutions and resource management; hegemony, myth and symbolic power in conservation success stories; tourism, poverty and conservation; and the transformation of social and material relations which community conservation entails. For conservation practitioners and protected area professionals not accustomed to criticisms of their work, or students new to this complex field, the book will provide an understanding of the history and current state of affairs in the rise of protected areas. It introduces the concepts, theories and writers on which critiques of conservation have been built, and provides the means by which practitioners can understand problems with which they are wrestling. For advanced researchers the book will present a critique of the current debates on protected areas and provide a host of jumping off points for an array of research avenues
