It's a girl!
The Smithsonian's National Zoo announced Thursday that its 2-week-old (but already smiling!
) giant panda cub
is female, and her father is National Zoo panda Tian Tian (tee-YEN tee-YEN).
Panda mother Mei Xiang (may-SHONG) was artificially inseminated with sperm from Tian Tian, as well as from a panda named Gao Gao, at the San Diego Zoo. A sample was recently collected to determine the paternity of her cub, born Aug. 23.
The second stillborn cub delivered one day later was also female and also sired by Tian Tian, officials said. The cubs were fraternal twins.
Keepers performed a den check Thursday morning, and all the signs show that the mother and cub continue to be healthy, Senior Curator Brandie Smith told the Associated Press. The cub is also starting to develop dark markings in her fur around the eyes, ears and back.
"It's got a fat little belly," Smith said. "It's very active, very vocal."
The 10-day mark is critical for survival, Smith said. At that point, keepers start to gain more confidence about the cub's health.
"We're finally starting to really celebrate," Smith added.
China owns the pandas at the Smithsonian's National Zoo. This cub is expected to stay with her mother for a little more than two years – until she is weaned – and stay at the zoo for about four years. Mei Xiang's only other surviving cub, a male named Tai Shan, was born in 2005 and was returned to China in 2010.
Mei Xiang gave birth to a cub last year after several years of failed breeding, but the cub died
after six days. Its lungs hadn't fully developed and likely weren't sending enough oxygen to the animal's liver.
