Unlike all other monographs on the Golden Eagle, each of which had a regional focus on the study area of the author, this book represents the most wide-ranging compilation of Golden Eagle research ever prepared. With over 175 authors reporting on more than 2000 combined field seasons, representing every biome where the species is found, this book marks one of the greatest attempts to describe the biology of any circumpolar species. Having more than 900 pages, over 1500 illustrations, many never previously published, this work represents a truly global achievement. It merits a place in the library of every ornithologist and raptor enthusiast.
