Great Blue Heron

Yesterday, at the John Heinz Wildlife Refuge, I watched a Great Blue Heron for a while.  It stood on the house for tree sparrows for a long time and I was hoping to see it catch a fish.  After a while I decided to move on and then I heard a loud squealing behind me and the Great Blue Heron decided to follow me and get closer to me. I found this very intriguing so I watched it for a while longer.  I captured some pictures of it as it got closer to me.  However, it did not catch a fish before the construction vehicle came and I felt the pressure to leave, so the gentleman could work.
