I've seen turkeys chase deer off on several occasions. Usually it was a yearling or fawn that wascurious and got a little too close to the turkeys private zone. We were scouting one day and at the end of a field were about 6 or 7 deer and one lone gobbler. One of the young does got too close to the tom and he popped her with his wing. She nearly did a back flip getting out of the field. All theruckus and dust flying spooked the other deer too.Itwas funny to watch. I've watched standoffs between coons and deer. The coons always prevail againstthe younger deer. I have a picture taken at a feeder where a coon is standing up with its front legs (arms?)spread out in a face to face confrontation with a doe. It's hilarious.
