excellent condition, paperback

This book allows an interested individual to often identify a bird by traces it has left behind. Every page of the book is high-gloss paper and there are hundreds of photos to support the text. The author breaks the book into sections; including but not limited to tracks, pellets, and feathers. This book goes to great detail differentiating the tracks, explaining the classes of bird tracks and why some species are uniquely different. This is by far the best book on feather identification. it has photos of about all the feather types for most American species.

This book is as authoritative on feathers and bird tracks as Oberholser is on past Texas bird distribution or Sibley is on plumages.

Variations in acorn usage, ground scraping, prey remains, even skull photos can be found.

In short, if you see evidence a bird was around, this book will show you which bird species it was. ( )
