This book is a great information pertaining to the gyrfalcon. But this book is not for the layman. You have to have a biology background to understand what the information is telling you. The authors take all the studies and research of the gyr and put it all into this book. But all and all, I agree, this book will answer any questions one would have of the gyr. As a falconer, raptor educator of the gyr, I have learn alot about this wonderful species that I did not find in other souces.
