In range, Wild Geese covers the geese of North America, Europe andAsia, and thus the world species except for the Hawaiian Goose orNe-Ne. Tbook is similar to the author's Ducks of Britainand Europe but distribution, status and migration rightly assume a moreextensive role in Wild Geese and the detailed text on those subjects isfully complemented by migration and distribution maps.Comprehensive chapters are also devoted to classification, ecology,breeding, identification, and to exploitation and conservation. Theidentification chapter is especially helpful with sections on adult andfirst winter birds, downy young, plumage variants and voice, for eachspecies and sub-species, as well as guidance on ageing and sexing geesein the field. The text is effectively supported by 16 identificationplates in colour by Carol Ogilvie, showing details of heads and billsspecies in flight and on the ground, and downy young.The author is an established authority on ducks and geese and has been a researchscientist at the Wildfowl Trust, Slimbridge, England, since 1960
