Mei Xiang and Tian Tian are the National Zoo's second pair of giant pandas. Both were born at the China Research and Conservation Center for the Giant Panda in Wolong, Sichuan Province. They are together for most of the day. It can be hard to tell the adult giant pandas apart, but Mei Xiang and Tian Tian do have a few differences, which are described below.

Tian Tian and Mei Xiang

Tian Tian (t-YEN t-YEN), the male, was born on August 27, 1997. His name means "more and more." Tian Tian has black "knee socks." The black band across his shoulders narrows in the middle. His eye patches are shaped like kidney beans, and he has two black dots across the bridge of his nose. He weighs about 264 pounds.

Mei Xiang (may-SHONG), the female, was born on July 22, 1998. Her name means "beautiful fragrance." She has black hip-high "stockings" extending up her hind legs, and the black band across her shoulders is wider in the middle than Tian's. Her eye patches are oval, and a pale black band runs across the bridge of her nose. She weighs about 233 pounds.

Mei Xiang and Tian Tian's second surviving cub was born on August 23, 2013 at 5:32 p.m. Keepers say it appears that her eye markings resemble Mei Xiang's. The black saddle on her back resembles Tian Tian's. She will be named when she is 100 days old.

Tai Shan, Mei Xiang and Tian Tian's first offspring, left the Zoo on February 4, 2010.

Tai with bambooTai Shan (tie-SHON) was born early in the morning on July 9, 2005. See photos of him as a cub.

More than 200,000 votes were cast to name him Tai Shan, which means "peaceful mountain."He received his name when he was 100 days old, on October 17, 2005. See the photo gallery. See a slideshow.
