Owl

Just had an interesting encounter with an owl.  Was walking through a grove of trees, it was dark, but could make out the branches, and there appeared to be lumps on the branches.  Thought, perhaps hawks or owls, if they were crows, there'd be more of them.  So, I stopped and looked up and asked, "Hey, are you an owl?"  Did not expect a reply, but a moment later, one of the lumps lets out a scream, and then began to hoot.  A bit freaky, alone in the dark, and also kinda' magical.  It stopped, looked down at me, and then flew off into the night.  Not sure about the other lump, it didn't react at all.  Perhaps it was just a bunch of unfallen leaves.
