Deer stomping

Deer are social creatures and, much like man, have a definite social structure. With this social structure comes a complex set of rules with which every deer in the herd must comply. These rules within the deer herd demand a method of communication whereby deer can react and respond to each other, establish herd hierarchy, or pecking order, and mutually warn each other of potential danger.

When deer detect a potential threat all of their senses are directed toward that area of concern. The deer assumes what is called a stereotypic alert posture. This posture includes the cocking forward of both ears and erection of the hair, particularly along the back. If a deer is unsure as to the actual presence of a threat, it will usually stomp a forefoot.

I have noticed that very often, if I move my head from side to side in a non-aggressive way, or if I stop staring at it or look away, the deer will stop stomping (and snorting) and just go back to eating. If it is still unsure, it will run away.
