Let me ask a follow up. Do turkeys drum without spitting? I have heard turkeys spit and drum on tape but not in person. Last Saturday I was out for the youth hunt with my son. We went into a wooded area that often has turkeys. On our way into the area we heard a loud noise up ahead that almost sounded like someone picked up a log and dropped it. We set up quickly and I did a few clucks and purrs and a couple of yelps. There was no response but we continued to hear the noise periodically for about 5 minutes. It came from the same spot each time. My son wanted to go and look but we held tight. Eventually, the sound stopped and we moved to investigate. I never saw any turkey sign in the area where the noise came from and never figured out what it was. It was not the classic spit and drum just a periodic thump. Any ideas?
