Figaro, a Goffin’s cockatoo amazed people with his uncommon ability. He chewed of a 2 ½ inch splinter of wood and used it to rake a nut that is beyond his reach from his cage.
Apart from the cockatoo, New Caledonian crows can also make tools; a skill that allows them to sustain their protein-dependent diet. But unlike them, cockatoos use general intelligence rather than a specific adaptation. They are an exceptionally intelligent breed of birds.
