Your crows and everybody else’s must be here visiting then. Last evening I watched a murder fly overhead that must have had over 1500 birds in it. 4 minutes solid of flying crows in a group 20-40 wide, never more than 5’ apart nose to tail. It was WEIRD!
I have only seen crows like that one time before.
It was in a place called “St. John, Kansas”. literally thousands of them.
