Tracks and Signs of the Birds of Britain and Europe (Helm Identification Guides) - Softcover

A guide to the tracks and other signs of European birds. It describes, using colour illustrations, the many physical signs that can be found in the field, from feathers and skulls to prey remains and pellets. The volume seeks to enable the ornithologist to establish the presence of a species without necessarily encountering the bird itself. This second edition is revised and updated to include more data and ten new plates of artwork, and it covers a number of extra species.
