In Urban Wildlife Management, we use a lot of tool to help us identify creatures. Lately, my favorite is my Truth Cam. This camera is marketed to hunters, but man does it work great in our jobs! Just have a look above. The house this fella came out of was sure there were rats in the foundation, you can even see a live rat trap in the lower left hand corner. To be sure though the trusty camera caught the true squatter making an exit. He couldn't quite fit into the trap to get at the peanut butter.
