恩賜上野動物園
Despite the treatments, Ling Ling died at the Ueno Zoo at approximately 2 A.M. on April 30, 2008, just one day after he was withdrawn from public exhibition. An necropsy found that he had died of heart failure. He was 22 years, seven months, and 5 days old, which is roughly equivalent to 70 years old for a human. According to the Ueno Zoo, Ling Ling was the oldest panda in Japan, as well as the fifth oldest known captive male panda in the world at the time of his death. Ling Ling's portrait and favorite food, bamboo shoots, were displayed in his cage following his death. Zoo visitors left bouquets of flowers and signed condolence registers.
