Quoted: IN “Oryx and Crake,” Margaret Atwood’s novel about humanity’s final days on earth, a boy named Jimmy becomes obsessed with Alex, an African gray parrot with extraordinary cognitive and linguistic skills.

Atwood based her parrot on one that died recently. But the real Alex was no slouch...

Quoted: “Want a nut!” Alex demanded. The interview was over. “Want a nut!” he repeated. “Nnn ... uh ... tuh.” Dr. Pepperberg was flabbergasted. “Not only could you imagine him thinking, ‘Hey, stupid, do I have to spell it for you?’ ” she said. “This was in a sense his way of saying to us, ‘I know where you’re headed! Let’s get on with it.’ ”
