Hooray! San Diego panda Bai Yun gave birth to the first of two baby pandas. Previously, on a routine ultrasound, San Diego panda keepers were surprised by Bai Yun's pregnancy and the fact that it was with twins. Also, they don't know who the father is. At any rate, the panda team is trying to see if there is another cub, but in the meantime, Bai Yun seems to be doing fine with the first (in the box outlined above - yes, panda babies look like rats at first - gross). Click here to see video of Bai Yun and baby - the baby's vocalization can be heard.
Zoologists at the National Zoo still don't know if Mei Xiang is pregnant.
