A wild prey animal will seem to have a 6th sense, but what it mainly is, is a supremely keen ability to locate predators. If they don' t pick them out they die. It is genetic programming and natural survival instinct at work.

WE are the predators and THEY are the prey if they don' t notice something about us we kill them. The ones who do look for/see us get away, and learn from that.

Deer learn by experiences. If some other hunter was in a stand and took a shot at that deer, missed, and it ran away the next time it gets into a similar situation, it will be more cautious therefore looking harder (and yes even looking UP).

Deer are keen on picking up on movement in their environment (whether bush or dense forrest). Once they identify the source of the movement they then rely on their experience to govern how they react. A deer that has been shot at from a stand will look for stands, and run once they locate movement in it.

They are getting smarter in that they adapt to predatory pressures, WHEN, and HOW the predators get there (in our cases vehicles). And the ones who don' t learn are either shot or hit on the road. But the ones that jave learned are the ones that seem to have a sixth sense.

Not being by the road once hunting season starts is simply over the last " X" number of years, when hunting season starts, they experience shots fired, vehicles more frequently. Eventually they avoid the roads at a particular time of year, to due more " predators" , and bad experiences near the roads. If they didn' t learn that then those are to ones that are generally killed from the road. Thereby selecting out the ones who haven' t learned yet. If they escape then they learned, and adapt appropriately!

Adapt or die (simple evolution)
