Nature Done Wright

On Monday, I asked:

What happened here? My neighbor's shutter appears t be the scene of a crime.

But what?

(I know the likely answer only because I once witnessed it happen…)

The likely answer, from Lisa Potash: "Something bat-related."

I think a raptor pinned a bat against this shutter as it returned from a night of foraging, and all that remained was a bat wing.
