Very cool looking buck! I suspect he's 4.5+. If you got that video back in oct-nov, I'd definitely say 3.5, but I wouldn't say that this late in the season.
As far as habitat changes correlating with buck appearances in late season, the more habitat changes we do, the more appearances we see. Over late summer last year, we created 11 new acres of food plots and roughly another 30 acres of select cut. We are seeing the same this late season as well. I suspect you'll see more and more of that especially because you'll have good thermal cover once those pine seedlings grow up and the added food plots you have. The trend your seeing is likely to continue.
A lot of our summer resident bucks left in October and came back within the last 3 weeks. Now, most of the folks in our camp say "that sucks" and "hate that they leave". I always look at the positives - in essence, they made it and I have until late October to kill one in the 2022 season
. I know you don't bow hunt, but there is still satisfaction in seeing a buck survive and show back up that you haven't seen in 3 months. In your opinion, do you think this buck in particular probably was a summer resident and you likely would have gotten pics of him if you still ran salt licks? But now that you don't and just have cameras over food plots, you may have just not picked him up?
