I wasn't quite sure wether to put this in health or training. We recently got a new gelding, he was supposed to be for my husband, but he hates him so I have been riding him. He has a habit of tossing his head up in the air. At first when my husband was riding him we were thinking it was the bit or his teeth, we tried 5 different bits on him. Since I have been riding him I don't think it is either. He only does it on a loose rein when we are walking along in a clear area. He does not do it trotting, or if the trail is a bit rougher and he has to watch his feet. Which makes me think he is doing it out of boredom. I was hoping for some outside thoughts on this and maybe some tips to get him to stop.
