Collins BTO Guide to British Birds

This new identification guide features all of the birds that have occurred 5 or more times in Britain and Ireland, including all species that breed regularly in the region, plus those that winter here, or occur as common passage migrants. The book has been written and illustrated as much with the beginner in mind as the experienced birdwatcher. Designed to be used in the field, the text and photographs describe and illustrate the key features needed to identify a species with confidence, and to separate it from similar, or 'confusion', species. As a general rule, the species accounts follow the taxonomic running order provided by the British Ornithologist's Union (BOU).
