In a unique new collaboration, Collins have paired up with the BTO, bringing together the most authoritative and up-to-date information in this new field guide to the rare birds of Britain and Ireland.
This book is the companion volume to the Collins BTO Guide to British Birds. It covers all the rare and scarce birds that have occurred in Britain and Ireland five times or more, as of February 2015. ‘The Rarest of the Rare’ section lists all the species that have occurred fewer than five times; taken in combination, this means that every species of wild bird that has ever occurred in Britain is mentioned.
Species descriptions comprise the bulk of the book, and the text and photographs describe and illustrate the key features needed to identify these birds with confidence. Confusion species are included, as are vocalisation details for species whose identification it aids.
