From my experiences, in densely populated areas where deer have abundant contact with humans, it seems that they definitely take notice ofthe human scent and will not proceed until they have accessed the situation. I have never seen a deer that has detected human scent continue on it's path toward the scent. Usually they will skirt the scent and try to remain undetected. They do not flee wildly, they slink around the offending oder as quietly as possible.

There are always cases where a deer is directly down wind from a human and does not seem to detect it or perceive it as a threat. These deer are usually deleted from the gene pool! [:-] I've killed deer under these circumstances as well. I always error on the side of caution when hunting these animals because once you're busted, they'll be doubly on alert.

On the other side of the coin, I've had deer approaching me from up wind that have suddenly stop, look around and decide that for some reason that it's not safe and go the other way!!?? I don't like giving them the chance to detect me before I can get a shot.
