One more thing to try, as soon as you know he is leavin his strut zone at the roost tree, slip in undetected to the roost tree area and softly call with a couple clucks, a few purrs and leaf scratchin and lots of patience. I think your best plan is to slip in at least 1hour before first light and get between him and the clear cut. Don't call until he is on the ground and comin your way, only soft purrs, maybe a cluck and scratch leaves behind you. Don't yelp to him!
