From the San Diego Zoo website:
"Bai Yun gave birth to a single cub today following a 2.5-hour labor. Our animal care staff observed parturition at 1:31 p.m. via a closed-circuit camera installed at the Giant Panda Research Station birthing den. This is a delicate period for the cub, but Bai Yun is an experienced mother and the Giant Panda Team will be monitoring the pair around the clock. The Zoo’s Panda Cam
will provide a sneak peek into the den within the next 24 hours.
The sex of the newborn will not be known for some time. The newborn cub is the fourth giant panda born at the Zoo, all of them to Bai Yun. The cub's father is Gao Gao."
