Hawks - probably the most popular birds among birders - are notoriously difficult to identify using the traditional field-mark method. Hawks in Flight show how to recognize hawks the way we often recognize our friends at a distance: by their general body shape, the way they move, and the places they are most likely to be seen. Pete Dunne's clear, lively text brings to life each species' distinctive characteristics , and their visual essence is captures in David Sibley's elegant drawings and Clay Sutton's photographs.
