Sad news from 3News.co.nz this morning. Lee the Kakapo, who could have been as much as 100 years old, has died a day before he was due to be returned to his island sanctury. He was successfully treated for lead poisoning recently, and everything seemed to be going well for him.

[Lee] died suddenly at Auckland Zoo last night from a small tear in the side of his crop, the sac-like part of the digestive system where food is stored before it enters the stomach.

"While working to repair this injury, Lee's heart stopped twice, but we managed to resuscitate him," said senior vet Dr Richard Jakob-Hoff. "However, he went into cardiac arrest again at the end of the procedure, and this time we were unable to bring him back - the shock on his system just too great."

With Lee's death, there are now a total of 90 Kakapos alive in the world, including the six chicks that survive from 2008's breeding season.
