LOL! Welcome to the deer woods!

Yes, the term is called "blowing", like a sharp whistle through their nose. I find it happens the most when they've smelled something they don't like. I've also seen them blow when they've caught a glimpse of me moving, but then I stop and they can't make me out. Most likely because I was wearing ASAT or Predator's copy of it. If you stay still there long enough, there's a good chance they will quit staring in your direction and go about their business.

It doesn't necesarily mean you're busted. You can wait it out and see what happens. Often you'll see the whole group get a little stiff from the commotion and sometimes, not often, they get over it rather quick.

If you want to hear the "blowing" or some call it "snort", check out the YouTube link below:

Good luck this year! And be safe to hunt another day.
