An alerted deer may play dumb to trick you. Sometimes a deer that senses something's wrong but can't locate the intruder will first extend its head forward for a better view. This will probably be the moment you pick to draw your bow or mount your gun. Suddenly the deer looks up, spots you, and bolts. Wait until the deer has calmed down.
Deer stomp their hooves primarily to warn other deer of danger .
The most important from the hunter's point of view is smell. Stomping deposits interdigital gland scent, a warning that this is not a safe place. If you alarm deer into stomping, you'd better relocate your stand.
