This is the first comprehensive field guide to North American warblers available. Featuring the unique Peterson Identification System, this field guide shows exactly what features to look for in order to tell one species from another. Like all Peterson Field Guides, Warblers is designed to work in the field...and every illustration and every word is directed to that end:
- 32 color paintings use the unique Peterson Identification System to clearly show marks that distinguish one bird from another – including fall as well as colorful spring plumages.
- 141 color photographs accompany the species descriptions.
- 60 color maps show where each species can be seen at different times of the year.
