Well, I wouldn't justify the fact that there weren't any hens with him or in his vicinity. In my experience, I've encountered many gobblers like this. When they are on roost, they tear it up, which is a natural trait they possess, but once they hit ground they either shut up, or just gobble hear and there. Why they gobble here and there is mostly because there's a hen in his general area and he'll continue to gobble until they within 10 yards from each other. Then he goes into full strut mode. He'll spit and drum until he breed her, which could take hours. Now my personal favorite time to hunt other than sunrise, is after 12 pm. Some states don't allow afternoon hunting, which really sucks. Because I've killed most of my nicest birds after 12. Reason being, is the tom has bred the hen(s) and is now just roaming the land looking for other hen(s) to bred. This is when a gobbler becomes the most vulnerable. Now, if you can roost a gobbler the night before the hunt, try slipping in as close as you can without busting him off the roost, and set up. Once flydown time approaches give him some soft tree yelps, followed by a fly down cackle. If this doesn't lure him in then I don't know what will. The method above (getting close before sunrise) lets you get to the gobbler before the hen does. Generally the gobbler flys down torward the hens at flydown time. So this opens up doors for a possible kill. Hope this helps and good luck the rest of 2006 season!
