Brown R., Ferguson J., Lawrence M., Lees D. Tracks and Signs of the Birds of Britain and Europe

London: Bloomsbury Publishing Plc, 2003. — 334 p.Featuring updated data for this second edition, this is a field guide to the tracks and signs of European birds. It describes, with 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 field ornithologist to establish the presence of a species without necessarily ever encountering the bird itself. Using the information provided, readers should be able to learn much about their local birds' habitat use and lifestyles. This edition includes ten new plates of artwork, and covers a number of new species.Field methods and Analysis
