An African parrot, N’kisi, has demonstrated an amazing grasp of the English language, with the ability to invent words and phrases when encountering new stimuli. He also shows evidence of a sense of humor. (from BBC News)

When he first met Dr Jane Goodall, the renowned chimpanzee expert, after seeing her in a picture with apes, N’kisi said: “Got a chimp?”

With a 950 word vocabulary and the ability to use tenses properly, N’kisi is not only one of the most advanced users of English in the animal kingdom, but also displays more language mastery than the average US public school student, President George W. Bush, and drummers.
