When a new American warbler appeared in a supermarket car-park near Maidstone, within two days 3500 people came from all over the country just to see it. The news spreads by word-of-mouth, by telephone hot-lines and via the media. In the UK bird recognition is a national sport. This book provides a field guide to the rare birds of Britain and Europe - describing and illustrating them - with all the non-European species ever recorded in Britain and Europe featured.
