Just to add something many haven't thought about:
Our trail cams are less sensitive, less likely to get pics of what's moving across in front to them, in mid-day vs any other time of day.
When I do all day sits, I often see deer walk close enough in front of a cam, that, that cam "should" get his pic. Yet the cam often doesn't. I also see a more random movement pattern during mid-day, such as an older buck doing more scent checking, and his travel can be more influenced by wind than established trails, scrapes, or anything else.
At night, no wind, a buck may need to stick his nose in a scrape to determine what other deer has recently visited. Mid-day, he may just walk 40 yds downwind, get no closer, and our trail cams simply fail to get his pic. Yet he was there, moving, mid-day.
There is often something magical beginning around mid-morning, when the wind starts picking up a little, just enough to rattle those beech leaves, just right to make rattling beech leaves sound a lot like walking deer. Bedded deer then get up and start walking too. Amazing how often I see this.
