A great guide to Michigan snakes. Pictures help you identify the snake that you may have observed in your back yard. I wish this was printed on higher quality print stock, but it is a nice resource to have on the shelf.
I have checked this out of the library many times...it may be time to purchase a copy. There is quite a bit of info about each snake. There are also some very good photos, including those of young snakes and distinguishing features. The only thing that I would change is to include more pics of different color variations. And maybe make it pocket sized...maybe not as it would shrink the pics-
