This field guide to the rare birds of Britain and Ireland is the result of an innovative new partnership between Collins and the esteemed British Trust for Ornithology. It brings together the most supervisory and current information.
The Collins BTO Guide to British Birds is accompanied by this book. As of February 2015, it includes all rare and endangered birds that have been spotted four or increasingly times in Britain and Ireland. Every species of wild bird that has overly occurred in Britain is mentioned in the section titled “The Rarest of the Rare,” which includes all the species that have only appeared four or fewer times.
This book, whilst not specifically a field guide, is a worthy wing to the rarities section of my library and certainly wets the want when considering what you could find at any time of year! Click on the link unelevated to purchase your copy:
