What is the world's smartest animal other than humans?

The chimpanzees are commonly thought to be, but with recent studies on parrots vocal abilities, and crows problem solving the title of 2nd most intelligent animal is up for grabs. Alex a parrot that learned to count speak and English (now decided) is a good example of animal intelligence, and studies done on new Caledonian crows show they are able to solve multistage problems.
