@plutus @johnserwach @rubecube12 @protecttruth That is likely a "crow funeral". When they see one of their own down (dead) they seem to summon huge flocks and fly around somewhat near the carcass in an agitated state like that.
I was in the middle of one once. Unbeknownst, a dead crow was on my rooftop. They were going nuts. I went up to have a look, and sure enough.
