Trail cameras have solved one aspect of the deer rut mystery for me at my location. I have been observing for several years now, and within a day or two either side of November 8 will be the peak daylight movement of any old bucks. This movement could just last a couple of days or it could be stretched out over a few more days in any given year, but right around that day will be it.
Since our rifle season starts the second weekend in November, the peak daylight movement has already passed or just passing by that time. Since the calendar changes each year, the second weekend can be close or several days off. But, we seem to do okay anyway if we just hang in there and put in the time. Peak or no peak, there will be some, although possibly minor daylight movement all through late October and most of November.
For us, November 2019 should be a super hot opener but 2020 should be super slow. Look at those calendars, and you will see what I mean.
The other thing the cameras have taught me is that the second rut in December would be a great time to be hunting on our place.
