Among the world's most popular birds, hawks can be some of the most difficult birds to identify. They are most often seen flying high above and at a distance. This new edition of the book that Roger Tory Peterson called a landmark integrates an array of carefully selected photographs, David Sibley's superb illustrations, and a clear, information-packed text takes raptor identification to a higher level. This edition covers all of the raptors that breed in North America, including those with limited ranges in Florida, the Southwest, and Texas. Hawks in Flight summarizes an identification skill set that used to take years to master.
