Yes, more reasons than one. It usually means your cover has been blown.
Then there is the sound that deer make when they are trying to smell you. Its actually an inhale not an exhale. Both does and bucks make this sound. They are trying to wind you. Generally they will circle around making this noise. They know something is wrong but cant figure it out either because of noise, or sight. Happens a lot if you are wearing camo. MANY people call this a buck snort. HAS NOTHING to do with being a buck. They are inhaling a ton of air through those glands right under their eyes. They do this over an over again until they catch a whiff or give up. They stomp often while doing it trying to provoke a response from the intruder and also as a warning.
I've heard it when in a tree stand and a deer up on the ridge has winded me, I have heard it when a deer has seen me moving but not winded me and even walking in the dark spooking deer in all ways. Definitely a warning sound to other deer as to somethings wrong, they do a foot stomp to get more info from you at the same time. I personally have only seen does do this, never a buck. All the bucks I see just exit the area, I've never had one stand around and make this noise .
