As new hardcover in dust jacket. Blind stamp on ffep. Many old world warblers are the archetypal 'little brown birds' and pose many identification problems for birdwatchers, but some are larger and brightly colored. 145 species are described in detail illustrated with forty-eight color plates and numerous line drawings and 140 color distribution maps showing breeding and wintering ranges. Sections on geographical variation, moult, voice, habitat and behavior, distribution, and measurements complete the guide.
