I live on a mountainside in northern Virginia. Lots of deer within my development and, since no hunting is permitted in that area, and they aren't bothered too much by people, they will frequently come pretty close to homes and munch on our lawns (and flowers or whatever tasty shrubs they happen upon). Last year around early June, I was watching a mature doe in my yard when I caught sight of a red fox running up along the edge of the lawn. The doe also watched the fox for a few seconds then suddenly tore off after it. I could not understand exactly what was happening. At first it appeared that she might have simply been playing with the fox, but as they disappeared into the woods behind my house, both of them tearing through the woods at max speed, I thought that maybe she had one or two young fawns up in those woods and she was making sure the fox didn't bother them. Still haven't figured out exactly what was happening. I have never seen a deer chase anything, except another deer - during rut or perhaps chasing one away from a food source. As I said, I think maybe she had young that she was looking out for, but I don't know that for a fact. Anyone have any other ideas as to what may have caused her to chase after that fox?
