Hone your bird watching skills. Learn more about birds using the very helpful Sibley Bird Guides. These books have awesome illustrations created by talented artist David Allen Sibley. He has drawn images of wild birds not only in a wide variety of plumages, but also from multiple angles. These make a difference as it is difficult to identify a flying hawk specie if all the pictures you saw were taken of a perched bird.

Sibley Bird Guides offer a brief description of each of the birds listed there. These books also have maps that point you to where you can see the birds in various parts of the United States. Each volume would be particularly helpful for birders with intermediate to advanced levels of experience in bird watching.
