A must have for serious birders in the Western Palearctic, even if you own the author's 2010 guide book. --BirdBooker Report, July 2011
It's a great reference companion for the original field guide, with additions and amendments to the accounts of nearly every species, all recent taxonomic changes and new species in the region, over 20 tables giving comparisons of the features of sets of similar species and a full checklist of Western Palearctic species.
