bad enough that a group of crows is called a murder. I do not doubt their intelligence.
OK, crows seem to be pretty smart; problem solving, communicating, and so forth.
But, here on the farm, I’ve been stalked by a few buzzzards, too. They don’t seem like they want to have tea and talk politics. I try to move faster when they are around, perched on a fence post while I’m brush-hogging the back pasture, watching me...always watching.
Stumbled on one trapped in a horse stall a few years ago. He was NOT a happy camper...
