No. They crawl into underground bunkers around 9:30 where they remain until an hour before sunset.[rofl]
Deer are in the woods all day and night. If you're there, there's a chance you can see one and kill it.
It's that simple.
I study wild deer on a daily basis in my yard. They move in "spurts". Of course dawn and dusk see a lot of movement, but even throughout the day, they get up and feed, then bed, feed, bed, feed, bed. They basically never stop. They typically bed for a couple hours, get up, move off browsing and then re-bed.
The thing is, the movement at dawn and dusk is greater because they are travelling to main food sources where they may feed most of the night.
The daytime movement is often limited to browsing near where they bed or travelling to well concealed food sources.
Most of the biggest bucks I've ever seen have been in the middle of the day too. And not just during the rut. They seem to have humans patterned, or it just works out that they move mostly at night and midday.
