Owl Being Harassed by Crows

Yesterday as I was walking in Valley Forge I heard crows barking in a remote corner of the woods.  I hauled my big lens and me over lots of dead trees to finally get to the racket.  There must have been 15 crows harassing this beautiful but highly annoyed Great Horned Owl.  She was not happy to see me either.
