TOKYO (Reuters Life!) - "Ten," a six-year-old New World parrot, can solve a puzzle consisting of two entangled chains in less than 30 seconds.

It takes humans about an hour.

The female macaw at a botanical garden in suburban Tokyo competes against more than a dozen human visitors every day, but remains undefeated.

"I can't do it! It's impossible!" said eight-year-old Yuto Uotani, after Ten solved the puzzle in a matter of seconds, using her beak and foot.

Other parrots have so far failed to beat Ten's record. Most of them pay no attention to the chain puzzle.
