Bai Yun, a 20-year-old panda, gave birth to the cub on Sunday afternoon and immediately scooped the cub into her arms and comforted it.
The pregnancy was considered high risk because of the mother's age.
This is Bai Yun's sixth cub born at the zoo, which is the most born at a breeding facility outside of China.
The cub's sex won't be known for several months, and it will be awhile before they're on display to the public.
