Interesting Imprint

So my husband opened the window blind tonight and as we where talking I was memorized by what I saw behind his head. Of coarse he is looking at me like WHAT (isn't that the worst thing when someone does that, LOL)! Well our window is distinctly marked with this image that looks like a bird. There are feather leavings on the lawn right under the window but isn't that crazy that it left this behind on the window.
