Is that a duck?

This is the building that is directly across the street from our apartment:


A couple of days ago, Napoleon and I were noticing how the awnings look like tire tread when Napoleon said, "Is that a duck?" It took me a second to figure out what he was talking about, but then I saw it too:

I said, "Yes, that is a duck. A dead duck." I pulled out my camera to take a picture and as I was zooming in I noticed another dead duck just above that one:


In the first picture above you can see both of these ducks on the left awning and just above it. I don't know why these ducks were flying through downtown Chicago, what killed them, or how long their bodies have been lying there, but I can't help but feel a little sad for them.
