Attacked by a Bird

This evening, around 5:30, while I was walking on campus toward my car, I felt something hit me on the right part of my head.  Looking around, I saw nothing but a beautiful long-tailed bird, which just perched on a tree.  My conclusion was: I was attacked by the bird!  Never have I had the slightest idea that I would have this kind of encounter with a bird. 

Well, I didn't blame it, though my head hurt a little then.   Maybe it didn't hit me on purpose.  It just passed by, with its wing or tail sweeping across part of my head.
