Almost certainly the best thing I wa ever told about owls was when I met an owl handler and he told me that the wild owls in the sanctuary where he worked worried about the tame show owls there and sometimes stopped by to leave them shrews and mice as presents.
It was one guy with a caveman mask and one with a Dick Cheney mask. Dick was ironically the neutral or good (control) person who did nothing and the caveman was the bad (treatment) person who once trapped some crows and then released them.
Wildly speculating but could it be that knowledge about skills of corvidae goes back a bit and Hitchcocks “The Birds” wasn’t just fiction?
