I bought a Texas IDentification book. That has plants, trees, birds, insects, animals, etc. But I also bought those glossy folding Guides for birds, critters, etc. They are usually pretty acurate on ID'ing my yard critters. I found them by the checkouts.
I love spotting a new creature and trying ID it. Not always easy to do. Sometimes it's an animal from another state that was blown here by a storm.
Good luck with Id'ing your creatures.
