I discovered this Northern Hawk Owl on a trip to the grocery store (best trip to the grocery store I have ever made!). It is evident that this Hawk Owl has a gash over its left eye; likely a talon of another Hawk Owl as there are not many raptors that will go after such an agile and aggressive bird. The Owl was doing quite well and has since moved on to greener pastures, or snowier pastures filled with voles I should say. Clarence-Rockland, Ontario, Canada. Canon 7D, 400mm f5.6L, tripod.
