oh no, crows are highly intelligent birds. Dunno about bluejays. Last one I saw flew into a window so hard it knocked itself out for two hours...not kidding either.
African Greys are also considered highly intelligent - some scientist I read about actually had an african grey she thought was capable of not just using tools, but of logic and reasoning skills too. It was in a national geographic or something. And they pick EVERYTHING you say up, so be careful if you get one and don't want it cussing a blue-streak. My ex-boss knew one that could be handed a piece of toast, look at it, go "want butter", and would hand it back until it got butter on the toast.
