The northern goshawk is one of the principal members of the forest raptor community that I investigated during graduate studies in the northeastern United States. As a wildlife biologist for Beak Consultants, I also conducted surveys, research, and GIS-habitat modeling on goshawks in the Pacific Northwest. In addition to that work, another part of my job was also to provide expertise on goshawk issues and remain current with the scientific literature on goshawks. After amassing a wealth of information, data, and field experience, it seemed like a natural step to compile this knowledge into a single handy source or reference book for people keenly interested in North American goshawks or raptors in general. While there have been several recent reviews on goshawk biology, I think that this book presents a unique perspective of experience gained from a biologist who has studied goshawks from coast to coast. In addition, one of my strengths as a scientist has been my ability to see the big picture and not get muddled in lengthy debate over minor details. Thus, I feel that this book presents a practical, logical, and holistic approach to the study and conservation of goshawks in North America. More than simply provide another review, I hope that I have synthesized the most critical elements of life history and scientific analyses into a thesis which provides a complete and comprehensive understanding of the goshawk.
This compelling story of heroism and tenacious human spirit— the first book to look at this momentous new movement—brings alive one of its most astonishing victories.
