Some years ago I shared this image in my post depredated bird. I see such configurations of feathers pretty often around here—the remains of a bird killed probably by a cat or hawk, or possibly a fox or coyote.
So I was somewhat daunted when I saw this configuration of sequins on the grass just outside my front door.

Does that not look dauntingly like the remains of a depredated party girl?
It makes me worry just a bit about about what the predator was.
