N'kisi the parrot is making waves with scientists with his unusual speech.
Unlike most parrots, who can manage the odd "Pretty Polly," N'kisi knows 950 words, and even has a sense of humour.
He invents his own words and phrases to deal with new ideas, just like humans. When he met a famous monkey expert, he asked: "Got a chimp?"
When N'kisi, an African grey, was tested by scientists, they found he used the right words three times more than would be likely by chance.
