Peterson's Perspective


Peterson's Perspective is a tutorial that will help teach novice naturalists about bird identification, birding, and birds. It is based on the Peterson Identification System created by Peterson in 1934. The foundation of the system is Peterson's visual categories, field marks, and size and shape. Peterson's Perspective goes beyond basic identification to cover a range of birding topics, from bird behavior, to migration, to attracting birds.

The Peterson Identification System was created by Peterson in 1934 for his first field guide to provide quick, easy identification of birds in the field by observers. It is based on clear illustrations of similar birds with important distinguishing field marks indicated. The birds are arranged in a system of visual categories based largely on their observable traits.
