Rating: - Essential reading for migration fans
This weighty and impressive tome, details information gathered by the British Trust for Ornithology and their partner organisations, through their various surveys, in particular through bird-ringing. The detail of bird movements is amazing, with details of the origins of birds coming to Britain and the wintering places of birds from Britain. The data used for this book is the result of years of dedicated work by many volunteer workers, who can now read the fruits of their labours, and as such is the result of generations of hard work and learning of literally hundreds or thousands of people. This book should be a reference to all serious birders and conservation workers alike. It is a simply magnificent piece of work!
