Four weeks after it was born, San Diego got a good look at its newest panda cub.
The cub -- a boy -- weighs 2.8 pounds and is 14.7 inches long.
San Diego was caught up in panda-mania in 1999 when Hua Mei, Bai Yun’s first club, was the first giant panda cub to be conceived by artificial insemination and the first American-born panda cub to survive to adulthood. She is now in a breeding program in China along with her brother, Mei Sheng, who was born in San Diego in 2003 through natural breeding.
Two of Bai Yun's other offspring, Su Lin and Zhen Zhen, born in 2005 and 2007 respectively, remain at the San Diego Zoo.
Following Chinese tradition, the cub will not be named until its 100 days old.
Mother and son will remain in the den for four to five months. During the denning period, the only way to see them is through the San Diego Zoo's live Panda Cam.
