Yun Zi

Yun Zi (Chinese: 云子) is a male giant panda born on August 5, 2009, at the San Diego Zoo, with an official global giant panda breeding registry studbook number of 760. He is the offspring of father Xiao Shuang and mother Xin Xin, both of whom were part of the long-term giant panda cooperative breeding agreement between Chinese and United States wildlife conservation institutions. His birth marked a notable milestone for the cross-border panda conservation partnership, as he was one of the cubs successfully bred under the decades-long collaborative program between the two nations.

In line with the terms of the Sino-US panda cooperation agreement, Yun Zi was transferred to the China Conservation and Research Center for the Giant Panda on August 5, 2010, his first birthday. Since his arrival at the facility, he has participated in the center’s captive breeding and species research programs, contributing to ongoing efforts to expand the genetic diversity of the captive giant panda population and improve understanding of the species’ physiological and behavioral traits. Caretakers at the center have documented that Yun Zi displays typical foraging and climbing behaviors common to his species, with a distinct preference for bamboo species native to Sichuan, China.

Yun Zi’s birth and subsequent cross-border transfer have served as a high-profile public case study for international giant panda conservation cooperation, supporting public education initiatives on the species’ vulnerable conservation status for audiences in both the United States and China. His early life in San Diego drew widespread public attention to the threats facing wild giant panda populations, while his integration into conservation programs in China has highlighted the long-term collaborative impact of global panda protection efforts. As a participant in the China Conservation and Research Center’s breeding program, he continues to contribute to the collective goal of building a sustainable, genetically robust captive population to support the long-term survival of the species.
