Knocking in Okaloosa County, Florida

I think I may have had a encounter the other day while me and 2 of my friends were hunting for wild hog on the yellow river WMA. We were in some super thick pine wood area that had a ton of hog sign which was right by the river and swamp area. We had just found a big sign of uprooted area from hog and we decided to sit for a second and see if we could hear anything. After a few minutes we heard a pretty big limb snap and I saw what I thought was a buzzard fly off, so not sure if it was the buzzard that snapped the limb or the result of the tree snapping which spooked the buzzard into flying off. A few minutes after that I heard what sounded like a person slamming a baseball bat in a tree 3 times (knock knock knock) very loud from around 100-150ft away and about 5 seconds after that another (knock knock knock) which sounded around 300-400 yards away. Our initial thought is that it was other hunters possibly taking down a tree stand since it’s the end of the season. With us thinking it was other humans we walked through the dense woods to the road and expected to see a truck parked along the side of the road on our way back to my truck. We did not see a single othe vehicle the walk back (and even drove the opposite way and no cars). And there’s no way given the location in the terrain that you could get to this spot other than by car. I know what woodpeckers sound like and unless the woodpecker was the size of a Pterodactyl it was not that. The first set of knocking was so loud there was no way it was anything I am familiar with. Given the fact there was no other cars in the area I honestly do not know what else could have made those noises.
