In range, Wild Geese covers the geese of North America, Europe and Asia, and thus the world species except for the Hawaiian Goose or Ne-Ne.

The plan of the book is similar to the author's Ducks of Britain and Europe but distribution, status and migration rightly assume a more extensive role in Wild Geese and the detailed text on those subjects is fully complemented by migration and distribution maps.

Comprehensive chapters are also devoted to classification, ecology, breeding, identification, and to exploitation and conservation. The identification chapter is especially helpful with sections on adult and first winter birds, downy young, plumage variants and voice, for each species and sub-species, as well as guidance on ageing and sexing geese in the field.

The text is effectively supported by 16 identification plates in colour by Carol Ogilvie, showing details of heads and bills as well as all species in flight and on the ground, and downy young.

The author is an established authority on ducks and geese and has been a research scientist at the Wildfowl Trust, Slimbridge, England, since 1960.
