The biggest commotion I ever heard a flock of turkeys make was caused by a Bald Eagle. A friend and I went deer hunting one afternoon and walked to two greenfields that were only about 200yards apart. I had the shorter walk so I was already in my shooting house when I heard all kinds of commotion. I heard turkey sounds that I couldn't even identify. After our hunt my buddy told me that an eagle had dove right over the flock of turkeys just as he was easing up to the field. He saw the whole thing. Interestingly, he said the birds seemed to run together in a big group after the initial dive bomb had taken place.
