I agree wholeheartedly with Adrian here!Gobblers particularly dominant ones have an established area they will stay in throughout the breeding season provided there are hens in that area!They may not roost exactly in the same tree but generally close by!What they do as Adrian stated as human intrusion comes upon them during hunting season is gobble very little to none on the roost!Dont think that a woodwise ole gobbler cant pattern hunters because THEY CAN!Not only will they stop gobbling on the roost but also fly away from would be callers due to past bad experiences!They will still due there thing through the course of the season as far as breeding is concerned but without mouthing off!I have killed many a gobbler late in the morning and even early afternoon as we can hunt till 4:00PM here Calif not neccassarily because of the hens leaving the gobbler to nest but simply because the majority of the hunters have left the woods disgusted over the silence!I have seen the woods on alot more than one occasion liven up as far as gobbling activity goes simply because the woods have quieted down as hunting pressure lightens up as the day progresses!Bottomline is stay in the woods till legal shooting hours are over and you might be surprised!!!
