This weekend marks the start of panda birthday season in D.C., for those who celebrate. It’s a busy time for local panda-philes, with three birthdays over the next month at the Smithsonian’s National Zoo. Adding to the stress (and panda-monium?): this is the last birthday they’ll celebrate in the District.

The pandas are on loan from China, an arrangement that was set to end in 2020. It was extended until Dec. 7, 2023.

Previously, there have been hints that a new agreement in the works would make sure pandas have a permanent place in D.C. But a spokesperson for the zoo declined to comment on such talks, if they are indeed underway.

The zoo’s two panda parents, Mei Xiang and Tian Tian, are panda senior citizens. Mom Mei Xiang is turning 25 this year, while Tian Tian is turning 26. In the wild, pandas live 15 to 20 years on average, while in captivity they can live to age 30.

The youngest member of the zoo’s panda family is Xiao Qi Ji, who is turning 3.

The birthday celebrations begin on Saturday, July 22, with Mei Xiang’s big day. She will receive panda birthday treats at 9am and 10am (watch live on the Giant Panda Cam!). Xiao Qi Ji’s birthday is August 21, and Tian Tian’s is on August 27.

If you want to celebrate at home, you can always make your own frozen panda treat, following the zoo’s special recipe. Try substituting steamed sweet potato for the fruit, “if you’re feeling extra panda-y,” the zoo says.

D.C.’s panda culture dates back to 1972, when Richard Nixon became the first U.S. president to visit mainland China while in office. Following the visit, China gifted the U.S. two of its native bears: Ling-Ling and Hsing-Hsing. Decades later, after both had passed away, China sent Mei Xiang and Tian Tian, in Dec. 2000. This time, though, the bears were on loan, and came with a condition that any cubs they produced be returned to China at age 4.

The panda loan was initially set to expire in 2010, and has been extended numerous times.

Mei Xiang and Tian Tian have had four baby pandas. Tai Shan was born in 2005 and moved to China in 2010; Bao Bao was born in 2013 and moved to China in 2017; Bei Bei was born in 2015 and moved to China in 2019. Xiao Qi Ji was born in 2020.

In China, pandas have been making a comeback in recent years, with 1,800 or more living in the wild. They are no longer considered endangered.
