I was taught that after the first week of opening season, the deer go nocturnal, and you're just not going to get a shot.
I found this to be balderdash in all but extreme cases. Now there is a difference in getting a shot at a deer that you can harvest, and getting a shot at a buck with a large rack. As others have said... that big, dominant buck with the big rack got that way because he's smart and wiley. If the rut has finished up for him... he's just not going to be stupid.
As for deer in general, they have to eat and move to stay warm, and thus in colder weather, they often have to eat well twice a day to maintain calories... and late in the season, by hunting all day, without leaving the woods for a lunch break, I've gotten deer when folks would swear up and down the deer only moved at night.
What was happening was the deer were feeding about an hour before dawn, then holding up for most of the day. A lot of the hunters were doing morning hunts, and leaving at noon, or breaking for lunch for about 3 hours, from say 11:00 to 14:00. What they didn't know was that the deer often moved at about 12:00 to 14:00 and ate, until they heard the hunters return, and went back to hiding....
I found that staying from first light until sundown, I often get deer after "lunchtime" or even at sunset. My last deer was the last day of the Black Powder season, 30 minutes before sundown last January.... when most of the other hunters that I know told me I was wasting my time.
Now, true, one year the deer behavior was that they ate at just before dawn, and just after sundown, so that was the toughest year that I have experienced, but it's not some universal behavior, and staying put all day will also give you the chance to pick off the deer that got spooked from a hide by a hunters leaving at the end of the morning.
