Interesting and thought it is a ritual of who might be boss. Yes these birds had 8 inch plus beards and were making a heck of a racket darning this behavior. There was one jake with a 2 or 3 inch beard and he was off to the side and watched what was going on. He didn't get involved and was chased a few times.
It is the dominance ritual going on. In my area there are usually more jakes who hang together and are always there off to the side doing their own dance. It doesn't take long for the long beard boss to be "nominated". Sounds like the age class where you are is older. We usually have a ton of birds here on the Island. Starting last year there weren't that many and there are way less than half the turkey as normal. Not sure what is going on whether it is predators or disease.
