Bowhunting mornings can be very productive.

The reason your don't see the celebrities bowhunting in the morning is that the celebrities don't want to wake up. They are hunting ground that has such a high concentration of unpressured deer that they have plenty of opportunity to make a kill in a hour of afternoon hunting. Also, they almost always will be hunting food plots and in this scenario they can expect the deer to come out in the late afternoon to feed. If they hunted mornings, they may bump the deer out of the fields.
