Roy Brown & John Ferguson 
Tracks and Signs of the Birds of Britain and Europe [EPUB ebook] 

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.
