(ECNS) -- A giant panda named Ershun gave birth to twin cubs late July at a zoo in southwest China's Chongqing Municipality, the zoo announced Monday.
This was Ershun's second delivery of twins and her first delivery after returning to China from Canada.
Ershun mated naturally with a male panda at the China Conservation and Research Center for the Giant Panda in the neighboring province of Sichuan in March, the Chongqing Zoo said.
The cubs weighed 132 grams and 91 grams, respectively, when they were born on July 22. They have reached a weight of 420 grams and 257 grams, respectively, the zoo said.
The giant panda Er Shun, 15, returned to China at the end of November 2020 after staying in Canada's Toronto Zoo and Calgary Zoo as a goodwill envoy since March 2013.
During her stay in Canada, Er Shun gave birth to a pigeon pair of cubs on October 13, 2015.
