Raven Brooch

Ravens are rated one of the most intelligent species of all.  A powerful logic, power to think ahead and the use of gestures to point in a particular direction are all possible by this bright bird.  And if that was not all, they can mimic human and animal sounds, sometimes for their own advantage, and will single out a cheater in their group if they spot one. Maybe this is why a group of ravens is called a conspiracy.
