Mei Xiang‘s surviving cub is male, the National Zoo announced Friday, and was fathered by resident panda Tian Tian.
The other cub born this month, who died earlier this week, was also male and fathered by Tian Tian. The cubs were not identical twins, a zoo official said.
The zoo has also preliminary determined the second cub’s cause of death as aspiration pneumonia, a complication that occurs when food material is aspirated into the respiratory system.
If the surviving cub continues to thrive, he could make his debut in January. The zoo has yet to determine whether he will be named after 100 days (a Chinese tradition), as was the case with his siblings, Tai Shan and Bao Bao.
