A guide to the North American wood warblers, the Parulinae, a brightly coloured and attractive group, which are distributed throughout the USA, into Central and South America. Some are also rare visitors to Britain and Europe. This volume in the Christopher Helm identification guide series follows the same format as previous guides. Introductory chapters are followed by the colour plates and distribution maps. There then follows full descriptions for each species, complete with wing formulae illustrations. An essential reference.
