xxx: My brother told me. Not about black crows, about ordinary grays.
xxx: Somehow his friend, who lived in a private house, went out into the yard to crack nuts. He was cracking them for some time, then a crow flies up to him and throws another nut. Well, it's not difficult for him, he split it for her, the crow ate it and flew away.
xxx: And after he went out into the yard next time, crows from all over the area brought him nuts. He cracked them all, and took some for himself.
xxx: So the crows hired a man to work for a salary)))
