Just like all other foxes around the area, grays eat small mammals that they find running around meadows and forests. Grays have the ability to climb trees unlike most of foxes. I wouldn't say they are as good at climbing as cats, but they do it from time to time.
This is one of my favorite camera locations. It is decently far away from where I live and have other cameras, so I only get to check it once every 6 weeks, or even longer.
The drive to get to it is nice, and the property owners love seeing the pictures, so it is well worth it for me to keep the camera there. If you're curious to know where it is, all I can tell you is that the camera is located in Lucketts, Virginia.
Here's another picture (of the infrared variety) of a gray fox in the same location.
Deer also showed up a lot and have been the most common animal on this camera.
