Like most folks mentioned it just depends. Here in eastern NC, I have seen very few deer in the morning and have never killed one during that time, all were in the evening. Now, that doesn't mean mornings are futile, just my experience. There are times here when the deer do in fact move in the middle of the day. Its just that when its 80 plus degrees, High Brass has a hard time getting motivated to hunt :x . In WV, I've shot deer from the first few minutes of daylight to the the last few minutes of daylight and all hours in between. Hunting pressure, seasonal temps, the rut, and food availability all come into play. So, in short I'd say that it varies year to year based on those conditions. The way I figured out how to kill deer here in eastern NC is to hunt hard and hunt often no matter what time of day.
