Hawks in Flight: The Flight Identification of North American Migrant Raptors
The standard field guides tend to assume that the observer will be close enough to the bird to pick out details of color and patterns for identification. Hawks, falcons, and their kin, however, are often seen in flight at distances far too great for color and pattern to be apparent: can they still be accurately identified? Yes, say the authors of this guide to the 23 most abundant and widespread raptors of the United States and Canada, who then show how with text and pictures. Serious birders can, and will want to, learn these techniques, so the book will be a worthwhile addition to all popular ornithology collections. (Photos not seen).
