We shouldn`t kid ourselves. They may not use the wind ALL the time but they do alot of the time.
Older deer anyway. The younger, less wary ones are all dead.
Some rarely move from cover during daylight, these deer I believe live by their nose. Introverts. These are the skulls we find, where the teeth are worn flat, and the pedicles are huge.
While you are gutting the deer that just walked in with the wind, he/she is standing in a thicket
waiting for your putrid smell to leave so they can "relax".
