There was a thread here a few months back (that I can't seem to locate) about a parrot that someone has been doing research on. It has a vocabulary of about a 4 year old, and can understand such concepts as "zero", and much other stuff.

Here's an external link for the story. Amazing!

You must be talking about Alex. He is a well studied bird and has documented exactly how smart they are. Somce scientists are beginning to think they are one of *the* most intelligent animals on earth, aside from humans. Everything from context speech to manipulating tools and incredibly dexterous feet and beaks seems to indicate this. Mine will even hold a spoon and eat nicely out of it.
