Polished wordsmith
He uses words in context, with past, present and future tenses, and is often inventive.
One N'kisi-ism was "flied" for "flew", and another "pretty smell medicine" to describe the aromatherapy oils used by his owner, an artist based in New York.
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?"

He appears to fancy himself as a humourist. When another parrot hung upside down from its perch, he commented: "You got to put this bird on the camera."
Dr Goodall says N'kisi's verbal fireworks are an "outstanding example of interspecies communication".
In an experiment, the bird and his owner were put in separate rooms and filmed as the artist opened random envelopes containing picture cards.
Analysis showed the parrot had used appropriate keywords three times more often than would be likely by chance.
