Crows win on intelligence. They are amazingly clever. This is good:

But even better – there was a programme about I think it was animal intelligenge, a guy had a raven as a pet that he used to put in a cage when he went out, to avoid any mischief. He suspected something was going on so he set up a camera and some bait for the bird. When he was gone, it cleverly let himself out of the cage and ate the bait. But the most incredible thing is that he got back in the cage AND LOCKED THE DOOR behind him. Not only is that extremely intelligent for a bird anyway, but the raven was thinking about what the human would think, putting himself in his place. That’s incredible for any animal imo.
