The closer the better but ya cant push him off the roost. Me if I get a 100 yards from him I figure Im doing good. 50 to 60 yards is pushing it. You wont know where he'll fly down too unless youve scouted the area. But if a field or logging lane is close chances are he will fly down to an opening. Asfor calls, you need to use your best call for soft calling while heson the roost. Ya cant blow him out of the tree with loud aggressive calls before daylight. Good luck
