Things that make you say "Huh?"

   Over the years, I've stumbled across some pretty weird stuff around Chicago.  This morning was no exception.  As I was walking on Wacker Drive, I spotted a bird's wing and it actually scared me when I first glanced at it.  Now I've become used to seeing random dead birds but never a bird's wing.  I'm guessing most of the dead birds that are sometimes seen on the sidewalks die because they fly into buildings or windows or maybe they even die from the elements.  I don't even want to guess how a bird's wing found itself on a busy sidewalk.
