Why deer foot stomp
We all know deer have several glands on their body. Between the hooves is a gland called the interdigital gland. This gland helps deer smell where another deer walked. It is also used to warn other deer of danger.
When a deer stomps its foot, it releases an extra amount of scent. This extra amount of scent warns other deer that there may be danger in this area.
If a deer stomps its foot by your stand and then runs or walks away, this scent is left behind. Whenever another deer approaches this same spot, even if it is hours later, it will know there is something wrong in this spot. It will be extra alert.
That is why a deer stomps its foot.
