@bojanfurst could it be, perhaps a bat house?
@bojanfurst @SisterArtemis
No, I don’t think so. It looks pretty much like a regular nesting box.
Maybe it’s to keep larger birds like Crows or Bald Eagles (both of which can be commonly seen around Quidi Vidi Lake) from preying/harassing on whatever is nesting inside?
@SisterArtemis That’s what I am wondering, too ! The spikes still seem a bit excessive :)
