Grizzer – Possession Rights

As you know, Grizzer lives alone, but he still displays possessive behavior and a desire to cache his food.  Why be possessive when you have no pack mates?  Scavengers are likely the motivator to protect his food resources.  When we feed either pack (Retired or Exhibit), a significant amount of ravens take advantage of the food resources and roost, waiting for the perfect opportunity to land and feed.  We also know that Grizzer can display his possession rights against the staff.  If staff are picking up scat and step on a cache, this can stimulate Grizzer to display threat behavior defending his cache.  He has the right to guard and possess food from the staff, it’s our job to look, listen and learn from the behaviors displayed by the wolves.
