The author, a life long, true outdoorsman and naturalist, has written a very detailed account of his professional experiences and personal reactions to them during his long career working with several species of eagles and other raptors as a NY DEC wildlife technician. While reading his semi auto-biographical/semi non-fiction journal type writing style with which he uses to express himself in this book, you will learn a myriad number of fascinating facts about these magnificent creatures and the importance of their vital roles and ecological niches in the grand and complex scheme of the wild natural world we live in, both in the Catskill mountains he calls home, as well as other areas of New York State, and the rest of the United States to which he traveled to study and train for the job. He explains how he gathered logitudinal data, captured and banded birds, and outfitted birds with monitoring devices. I enjoyed reading it immensely, and obtained a copy to keep on display in my own Catskill Mountain second home/Airbnb rental, where I and my guests often get to observe these birds ourselves as it is a riverfront property where they hunt for prey. I highly recommend it as a compelling read that also contains valuable suggestions regarding practices in which to engage to promote their health and successful lifecycles, as well as prevent illness and injury to our national symbol and other raptor species, so they may continue to grace our homeland with their existance and beauty for perpetuity.
