The Warbler Guide.

A classic reference for birders, The Warbler Guide makes warbler identification easier and enables you to quickly identify any of the 56 species of warblers found in the United States and Canada. Winner of a National Outdoor Book Award in Nature Guidebooks, this groundbreaking guide features more than 1,000 stunning color photos that show multiple viewing angles, extensive species accounts, and a new system of vocalization analysis that helps you identify songs and calls.

Published by Princeton University Press, authors Tom Stephenson and Scott Whittle provide “visual quick finders” to help you identify warblers from any angle, and their “song and call finders” make identification easy using a few simple questions. New aids to warbler identification include icons for undertail pattern, color impression, habitat, and behavior. Detailed species accounts show multiple viewing angles using photographs of birds in the field, complete with diagnostic points. There are complete age and sex descriptions of each species, along with direct comparisons of plumage and vocalizations between similar species.
