This book is intended as a reference companion for the original Advanced Bird ID Guide, the ground-breaking title by the same author that relies on characteristic lists to assist with species identification.
This new volume has larger and more widely spaced text, and more than 100 additional pages, making it easier to use. The accounts of 570 species have been updated or amended, and recent taxonomic changes and the discovery of new species has been accounted for. Twenty-three tables give side-by-side comparisons of the features of sets of similar species, and a full checklist of Western Palearctic species is included at the end of the book.
