I used to hear this said a lot, Especially from old school hunters, but I used to hear from them that a lot of the older age class bucks would get up and move around noon when most hunters were already packing up and leaving the woods. I'm sure there's some truth to it, and it may be a situationally specific thing, but I want to know everyone else's opinion on this.
Very much situational, and depends on location, habitat type, and hunting pressure.
We see virtually no mid-day movement from mature bucks
in areas hunters prefer to hunt. Are mature bucks moving mid-day? Possibly, but they are limiting it to areas hunters don't hunt (near-zero visibility thick cover). Now middle-aged bucks (2 1/2 and 3 1/2 year-olds) do some mid-day movement, but it is still the low-point of the day for movement in huntable locations. Below are two graphs from an ongoing research project of mine. The first graph is the time of day (in one-hour increments) middle-aged bucks were captured on trail-cam October through December in common hunting locations, such as scrapes, food plots, terrain and habitat funnels, etc. The low-point of the 24-hour cycle are the hours of noon to 1 PM, and 1 PM to 2 PM. Now again, are middle-aged bucks not moving at that time? Probably they are,
but NOT in common hunting areas. They are sticking to thick cover. The second graph is the same data for only mature (4 1/2+) bucks. Notice they are even more nocturnal than middle-aged bucks, and move even less at mid-day. In the 14 years of data, not one trail-cam picture has been collected of a mature buck up and moving between noon and 1 PM. Again,
this doesn't mean they aren't moving, it means they aren't moving in common hunting locations at this time.
And for those who are wondering, this data is not being skewed by small datasets. This data includes over 4,000 trail-cam events (an "event" is a buck triggering the camera. Doesn't matter how long he hangs around or the number of pictures taken, it is still just one event).
Now is this data true for everywhere? Absolutely not! It is accurate for just the study area, the study area's terrain and habitat, and the study area's level of hunting pressure.
