The last 2 years me and my hunting partner have had the repeated issue of elk responding to bugles but moving away from us. They will respond to our location bugles or cow calls, but as soon as we move in and start bugling they move away, They will still respond and bugle back but keep moving off. We keep trying to close the distance and dog them to get them to turn and come in, had some success with that last year. We are anywhere from 60-200 yards from the bull, wind is good and they didn't see us. My hunting partner has hunted there 4 or 5 years previous and said he has never seen the elk act like this. Usually they will come in to fight or come in silent to check out who is there. I don't know if perhaps there is more pressure and the elk are getting educated. What we can't figure out is why they act like this, maybe it's us, or a good tactic to use in these situations.
