Bird Tracks

Více o knize

"This guide contains life-size illustrations of 55 common and not-so-common bird tracks. Left-side tracks are shown. Some birds leave distinctive tracks that are easy to identify to species. Many others leave tracks that closely resemble those of related birds. I have done by best to include both the most distinctive tracks and enough representative examples to help you narrow down most other clear tracks you may find in the field." - cover verso
