Richard sent me this and it is quite funny. They are very smart birds and but can cause quite a nuisance to people and such people have been know to throw rocks at them and shoot them with b-b-guns. A good friend who will remain nameless was great at using a sling shot to get rid of them.
I feel quite friendly to crows at the moment but then I am not currently bothered by them. I didn't know they could learn to talk!
