The REAL Reason Ursids Rubs on Trees

There have been several theories as to why ursids rub their backs on trees.  Some think that it's a means of marking territories.  Another, more recent, claim is that bears actually do this as a means of establishing a baseline "scent similarity."  This way, if a new bear enters the territory of another bear there will be less of a chance for conflict because the intruder may think something to the effect of, "Hey, I recognize that smell!  This must be his territory.  I should probably not fight this dude because he has a lot invested in this particular area of land."*  Alternatively, there is the scenario as described in the video; I feel particularly inclined to cast my lot with this theory.
