Book Description
Warblers are the archetypal "little brown birds" that pose so many identification problems for birdwatchers. These problems are sometimes complicated by the fact that not all warblers are brown and small; some are brightly colored and relatively large. Jeff Baker helps novices and experts alike to steer away from such confusion in a unique book covering all old world warblers in Europe and Asia. The book describes in detail 145 species, including all aspects of identification and those species that are likely to be confused with one another. Sections on geographical variation, moult, voice, habitat and behavior, distribution, and measurements complete the guide, together with forty-eight color plates and numerous line drawings presenting every species and 140 color distribution maps showing breeding and wintering ranges.
