A must have for wildlife lovers
Format: Paperback
Wow! What an excellent and thorough compilation of scat and tracks. Nice reference for when you take pics and bring the image back to the book for comparison. Also, great information about tracking.

Good but index needs improvement
Format: Paperback
This is a good, comprehensive guide to tracks and sign.
However, there is no index of where to find each family, so in order to find a species you have to flip through the entire book looking for the right page. This makes it annoying to use if you are trying to look up information on a particular species or family.

This is a very useful field manual for those interested in detailed traking methodology.
Format: Paperback
I spent many years as interpreter and ranger for the Colorado State Park System, now called CPW—Colorado Parks and Wildlife. We were annually tasked with surveying a given species' presence, density, and range in the park system and surrounding areas. Detailed field manuals were critical to the accuracy of our work, and HOW I WISH I HAD THIS BOOK DURING THAT PART OF MY CAREER. There are few other books I've come across providing detailed, yet very accessible information on how trail sign reflects animal behavior across different conditions, landscapes, and seasons (both weather seasons and mating seasons). One particular aspect of this book I found significantly intriguing was the section on predation—how does a mountain lion take down a mule deer vs. how wolves bring one down. The locations on a prey animal where a certain predator is most likely to attack, showing illustrations, is a remarkable piece of work, and there authors are clearly masters of interpreting tracks and sign! If you want learn about how mammals behave in their native environment, adding this book to your field manual packet will greatly expand your horizons! Busy it, read it, and get outside! Thank you Mr. Elbroch and Mr. McFarland for adding to the wildlife canon!

Great book and very useful tool to have
Format: Paperback
I had the older edition and lived it, but someone at my last job *borrowed* it and I never saw it again. This edition sends even better than the last, and I have that one five stars. Great pictures and the number of species covered means it's good in at least all states I've worked in.

Simply unputdownable
Format: Kindle
B N William’s field guide is fascinating. The book uncovers the bizarre reality beneath the polished propaganda of the Second World War, exploring the wonderfully weird truths where the line between brilliant innovation and sheer insanity vanishes completely. Every unusual piece of information has been verified using official declassified archives. I loved the story of Wojtek, a Syrian brown bear, who became a beloved and legendary figure, known for his unique story as an enlisted soldier. Read many more such stories and episodes in this book. You will enjoy them thoroughly.
