S.McArthur, good luck on the bird. May not work but if you tried different calls on him and you think it's the blind he's wise to, try building a natural blind closer inside his range, leave or continue to setup your original blind as you have done as a distraction type "decoy". Though part is getting in and out to build the natural blind when he's not in or around the area. Good luck, sounds like a smart bird. Just saw your video, why did you set your decoy so far from your blind ?
