To further elaborate on the above statement:
This past summer, while groundhog hunting, I was sitting on a high spot overlooking a field, that had a brushy creek bottom in it, which was also divided by a hedgerow of Multiflorarose on one side of the creek. I observed two Red Foxes enter my view together and it was obvious they were hunting. They soon split up and started hunting on opposite sides of the bottom and hedgerow, they were as much as 75-100 yards apart as they traveled down the bottom. While hunting slowly and methodical, they would each call out to the other every yards of travel, using a bark identical the Red Fox Rally on my FoxPro FX5. They paralleled each other's course down the creek bottom for a couple hundred yards, and eventually one of them made a kill on a young rabbit. With his prey in his mouth, he immediately turned and made a direct route to the exact location of his mate, without further communications with each other, they knew where the other one was even after several hundred yards of travel down the bottom.
It was neat to just sit and watch the whole thing unfold before me. They were definitely communicating and keeping track of each other.
