Tian Tian (Chinese: 添添; pinyin: Tiān Tiān; literally "More and More") is a 275-pound male giant panda at the National Zoo in Washington D.C. The panda was born on August 27, 1997, at the China Conservation and Research Center for the Giant Panda at the Wolong National Nature Reserve in Sichuan Province, to Yong Ba (mother) and Pan Pan (father). Tian Tian is the half-brother of the San Diego Zoo's Bai Yun.
Giant pandas are thought to be solitary creatures, except for mating season and mothers with young cubs. In keeping with the habits of wild pandas, Tian is generally alone, although the zoo's female panda, Mei Xiang, and Tian are occasionally together outside of breeding season. While Tai Shan was still at the National Zoo, Tian and Tai occasionally viewed each other through a mesh-opening in the fence and were aware of each other's presence through scent marking. Male Giant Pandas play no part in raising their young in the wild. Tian and Mei are trained to participate in a full medical examination, including a blood draw, without anesthesia.
Some of Tian Tian's semen was preserved cryogenically, and given to Mei Xiang via artificial insemination in 2012. Mei Xiang gave birth to a second cub on the night of September 16, 2012.
On August 23, 2013 Mei Xiang delivered a cub at 5:30 pm, and then 23 hours later, delivered a second stillborn cub. Both were determined to be Tian Tian's and were females.
