Don't sweat it, he'll be back. I'd give him a day or two then try him again. Probably the reason he was still in the tree was because of you calling to him. He was waiting to see the hen before he pitched down. Thats one reason I don't call to them until their on the ground. Next time I wouldn't call to him until his feet are on the ground, but if you feel you have to call to him on the limb I wouldn't do anything more than a few soft tree yelps followed by a flydown about 10 minutes later. Then I'd just scratch in the leaves until I knew he was on the ground.
