Just got my copy of "Hawks From Every Angle" by Jerry Liguori today from Amazon. It's great. It has comparable color photographs to Wheeler's "Raptors of Eastern North America", which are excellent. The best part for me is the black and white photos which depict shape characteristics of different species and compare them to one another. The page comparing Sharpies, Coops and Goshawks will help us all!
