The Crossley ID Guide - Raptors

Part of the revolutionary Crossley ID Guide series, this is the first raptor guide with lifelike scenes composed from multiple photographs--scenes that allow you to identify raptors just as the experts do. Experienced birders use the most easily observed and consistent characteristics--size, shape, behavior, probability, and general color patterns. The book's 101 scenes--including thirty-five double-page layouts--provide a complete picture of how these features are all related. Even the effects of lighting and other real-world conditions are illustrated and explained. Detailed and succinct accounts from two of North America's foremost raptor experts, Jerry Liguori and Brian Sullivan, stress the key identification features.
