At least 63 percent of the world's raptors migrate. Raptor Watch, compiled from contributions by over 800 observers worldwide, is a guide to 388 hotspots where these birds can be seen in their thousands. A repository of information for the specialist, this book is also a strategy document enabling conservationists working at the local and national level to cooperate globally to protect raptor migration networks.  ""The most geographically complete reference list yet on hawk migration. A great starting place for anyone interested in witnessing or studying hawk migration anywhere in the World"" - Birding (October 2001).

Raptors are formally classified into five families and include birds―such as eagles, ospreys, kites, true hawks, buzzards, harriers, vultures, and falcons―that are familiar and recognized by many observers. These diurnal birds of prey are found on every continent except Antarctica and can thrive in seemingly inhospitable spots such as deserts and the tundra. They have powerful talons and hooked beaks for cutting and tearing meat, and keen binocular vision to aid in their hunting prowess. Because of their large size, distinctive feeding habits, and long-distance flight patterns, raptors intrigue humans and have been the subject of much general interest as well as extensive scientific research.Keith L. Bildstein has watched and studied raptors on five continents and is well prepared to explain their critical importance, not only as ecological entities but also as inspirational tokens across natural and human-dominated landscapes. His book offers a comprehensive and accessible account of raptors, including their evolutionary history, their relationships to other groups of birds, their sensory abilities, their general natural history, their breeding ecology and feeding behavior, and threats to their survival in a human-dominated world. Biologically sound but readable, Raptors is a nontechnical overview of this captivating group. It will allow naturalists, birders, hawk-watchers, science educators, schoolchildren, and the general public, along with new students in the field of raptor biology, to understand and appreciate these birds, and in so doing better protect them.

Review\n"This is the first scientifically grounded, engagingly told review of the ecology and conservation of the iconic bird group we know as vultures. No other book has come close to the depth, scope, and intrigue of Vultures of the World." -- Allen Fish, Director of the Golden Gate Raptor Observatory, Golden Gate National Parks Conservancy\n"A treasure-trove of important information for both those that already love vultures and those that surely will after reading this book." -- Munir Virani, Executive Vice President of The Peregrine Fund\nIn Vultures of the World, Keith L. Bildstein provides an engaging look at vultures and condors, seeking to help us understand these widely recognized but underappreciated birds. 
Bildstein's latest work is an inspirational and long overdue blend of all things vulture. Based on decades of personal experience, dozens of case studies, and numerous up-to-date examples of cutting-edge science, this book introduces readers to the essential nature of vultures and condors. Not only do these most proficient of all vertebrate scavengers clean up natural and man-made organic waste but they also recycle ecologically essential elements back into both wild and human landscapes, allowing our ecosystems to function successfully across generations of organisms. With distributions ranging over more than three-quarters of all land on five continents, the world's twenty-three species of scavenging birds of prey offer an outstanding example of biological diversity writ large. 
Included in the world's species fold are its most abundant large raptors―several of its longest lived birds and the most massive of all soaring birds. With a fossil record dating back more than fifty million years, vultures and condors possess numerous adaptions that characteristically serve them well but at times also make them particularly vulnerable to human actions. Vultures of the World is a truly global treatment of vultures, offering a roadmap of how best to protect these birds and their important ecology.
