Strange Turkey Mating Dance

I was hunting and this tom was strutting for a hen and started doing this strange dance or something. I've never seen it before wondering if anyone has an idea what the deal is. i posted it to youtube so you can view it...its about a minute in when he starts doing it. http://www.youtube.com/watch?v=eULkfekkxOE&feature=youtu.be

Normally that "dance" is the way a tom breeds a hen but it was weird because there was no hen underneith him!

Agree with Mike - I had a jake "Make love" to 3 different corn stalks on his way to my decoys. Just couldn't contain himself. Have it on film and watched it many times (hope that doesn't make me some kind of a sicko). I was guiding for a youth hunt. When the kid asked asked what he was doing, I let the father answer

interesting thank you......been doing this for 10 years and never seen it....poor guy didn't get what he was looking for ha
