Cai E

Cai E (Chinese name 彩娥, studbook number 1152) is a female giant panda born on August 1, 2019, at Moscow Zoo in Russia. She is the first giant panda born in the country in decades, a milestone tied to the 15-year giant panda conservation partnership established between Chinese wildlife authorities and Moscow Zoo that same year. Her parents, male panda Ding Ding (studbook number 1150) and female panda Ru Yi (studbook number 1151), arrived at Moscow Zoo earlier in 2019 as part of the collaborative agreement, which focuses on ex-situ breeding research, habitat protection advocacy, and cross-cultural public education around giant panda conservation. Her birth was widely celebrated by both Russian and Chinese conservation teams, as it marked an early success for the long-term bilateral program.

Cai E has resided at Moscow Zoo for her entire life, where animal care teams maintain her enclosure to replicate the cool, temperate forest habitat preferred by wild giant pandas, with specialized climbing structures, foraging enrichment, and access to fresh bamboo sourced to match the nutritional profile of bamboo native to giant pandas’ natural range in central China. She displays typical species-specific feeding behavior, consuming over 30 kilograms of bamboo each day, alongside supplementary dietary items tailored to her age and health needs. Zookeepers and research staff monitor her diet, activity levels, and physiological metrics on a daily basis, with all standardized data shared with the global giant panda studbook management system to support coordinated species conservation efforts.

As a high-profile representative of international collaborative conservation, Cai E draws consistent public attention from visitors to Moscow Zoo, and her public viewing areas feature educational materials that explain the threats facing wild giant panda populations and the role of ex-situ breeding programs in supporting species recovery. Her genetic lineage, as part of a well-documented breeding pair, contributes to global efforts to maintain a genetically diverse, viable ex-situ giant panda population, reducing the risk of inbreeding and supporting the long-term resilience of the species. She also serves as a prominent cultural symbol of friendly diplomatic and conservation cooperation between China and Russia, with regular updates about her growth and activities shared across both countries to build public support for cross-border wildlife protection initiatives.
