Could have been a window strike that a Coon found?

Owls do that. Evidently the head is the best part.

It was far from the window. I have never seen an owl here, but they are probably hard to spot. In any case, the body disappeared overnight, probably eaten by a opossum or raccoon.

I just had the same thing happened to me. I'm sitting in my backyard then all of a sudden I hear a bang right next to my head. I just thought a bird hit my sliding window, which is not uncommon. I reach down to help the little guy up only to discover it had no head. At first I thought it was decapitated from the impact. Then I realized the bird was some predators meal.
I've seen a lot of hawks but never any owls in my area. I've only heard any owl once in my area.
This Happened at about 2pm. It was pretty crazy.

Crows, jays, and grackles often prey on smaller birds, decapitate them, and (gulp) dine on the brains.
