DUSTWRAPPER TEXT
New World warblers are one of the most colourful, popular and enigmatic groups of North American birds. This is the first comprehensive guide to the identification, ageing and sexing of all 116 species.
Thirty-six colour plates show the major age, sex and racial variations for all species (many of which have never been illustrated before). They are accompanied by colour distribution maps and black-and-white drawings. Jon Curson's up-to-the-minute text is based on over ten years' field research in North, South and Central America coupled with meticulous museum work by both author and artists.
New World Warblers represents a significant step forward in our knowledge of one of the most beautiful and conspicuous groups of North American birds.
