This text presents a collection of field descriptions and photographs of the world's wildfowl. It covers 236 species and sub-species and 700 photographs illustrate not only the adult bird, but each significant plumage variation. The up-to-date species descriptions include details of habit, range and status, characteristic plumage features, sub-species and races where appropriate and vocalization. The book has been designed to complement and enhance existing artwork guides, such as "Wildfowl: An Identification Guide" (Helm, 1988), and covers rare birds, seabirds, birds of prey and warblers in all zoogeographic regions.
