Tons of info!
Format: Paperback
If one wanted to be a real tracker, this book has everything needed. I just want to be able to recognize the local wildlife tracks. But having all the rest of the info is nice, and it's easy to take what I want. The book is well organized. Fantastic pictures, loads of information. It's interesting too, to see just how much knowledge goes into figuring out not only what animal it is, but what sex, age, gait, etc it is. This is an awesome book.

Caveats for the professional tracker
Format: Paperback, Format: Paperback
This is a most excellent resource, arguably the best single tracking book that exists (i would argue so, if i had to pick one! And i recommend this book often). However, if you are in a professional field where this legally matters (EIS or ESA decisions on wolverine/fisher/lynx, etc.), take heed: the authors’ methods of measuring tracks are confusing (i.e. - where is the line between substrate/mammal family to determine when claws or ‘posterior’ pads are or are not used in measuring tracks? ) Also, the claim that “an individual animal can show incredible variation in track size” (p.57) is very misleading… Foot size of an individual animal from birth to adult will obviously change, but will not change in a day for the same-aged individual animal regardless of whether it walks in mud or atop rock. The animal’s foot does not change in size, but its track might appear to. This perceived “change” could be easily avoided by using minimum outline measurements (which are not discussed in this book, but can be found in the work by J. Halfpenny and others). I understand their reasons, but please do not refer to this book for legally defensible measuring techniques of rare species!!!! Also please disregard the negative reviewer who said “it’s a very Mythological Approach to how animals move and walk (jsopel),”- they clearly don’t know what that word means… All in all a well-researched and fantastic book that comes from ample and legitimate experience. A great book and happy 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!
