Fox Behavior Predator Calling

This fox was encountered when out hunting wild dogs. The foxes are often left alone if I'm out there to specifically target wild dogs. Foxes are often called in as it is a similar night hunting method. This is a great example of how a predator will often circle the "prey" in this case me and a caller. Just to get downwind to be certain what the animal is. Or in this instance, Identify the threat and get the hell outta there !!!
