The author, Dr Myrfyn Owen, is a Conservation Research Officer for The Wildfowl Trust at Slimbridge in Gloucestershire, where he has worked since 1967. Dr Owen has drawn widely on a multitude of sources including his own research to provide a comprehensive and systematic account of our present knowledge about wild geese, their life cycle and the ways which they adapt to the changing environment.

The species and their variations are fully described in the first part of the book, through summaries of the known details of, for example, summer and winter distribution, numbers, migration, breeding habits, food, plumage, identification and ageing.

 

Many of these aspects are illustrated by the accompanying line drawings, maps and tables. The second part of the book synthesises and analyses such aspects as the social and sexual behaviour of geese, summer biology, population dynamics, conservation and exploitation.

 

The species, and particularly the subspecies, are illustrated in the specially commissioned watercolour paintings by Joe Blossom.

 

Although some of the author's analyses are speculative they will stimulate interest in and work on the basic biological problems, on the understanding of which our attempts at goose conservation and management must depend. 

The book will be of particular interest to the keen amateur and professional ornithologist, wildfowler, wildfowl biologist and conservationist. 

It is an invaluable work of reference containing all the important information about geese and providing a fascinating account of the evolutionary and ecological basis for the major differences and similarities between species.
