I always bring up the story of Madge, my troublesome doe, in cases like this. My experiences with her just go to show you how variable and capricious this can be.
Madge got on to me over a couple of years and was forever searching me out at this one stand. When she'd find me, she'd stand there and snort and stamp-- sometimes for 20 minutes at a time. The other deer just ignored her and kept grazing for acorns. This went on for two seasons. It got to be like this weird game of hide and seek with Madge. I don't know why she never decided to just give up and stay away from that one oak grove.
The point is with some deer, they get wise and go away and never see them again. Others never get a clue and don't connect the dots and come back time after time and it's always a fresh experience for them. Some never learn to look up, and always think that the smell is coming from something unseen on the ground (I've got a couple like that now.) You just don't know.
Part of my practice is to try and keep the deer from patterning me. If they have a week or more to come back around the stand and see that whatever it was is gone, they're more likely to come back. It's also a matter of why they're at the stand in the first place. If this is a major travel route or a major feeding area, they'll probably be back. I've taken a deer out of a middle of a herd one weekend, and had that same herd back chowing on acorns the next weekend. On the other hand, if this is a place that is non-essential to the deer and they aren't depending on it, they may adjust their travel schedules or travel routes and you never see them again.
