Giant panda cub born at Zoo Atlanta

This video still shows mother giant panda Dan Dan looking at her baby (bottom) at Oji Zoo in Kobe, western Japan, on August 26, 2008. The cub, whose rare birth by artificial insemination led to rejoicing in Japan, died on Friday after just three days, zoo officials said.

Zoo Atlanta's giant panda family just got larger.

Zoo spokeswoman Simone Griffin says the cub is the only one born at a U.S. zoo this year. It comes just a week before the second birthday of their cub Mei Lan.

Zookeepers are watching to see if Lun Lun will have twins. That happens about half the time.

Keepers won't know the sex of the cub for a few weeks. They can't examine it until Lun Lun lets them touch her baby.

Mother and cub won't appear in public for several months but can be viewed on the zoo's webcam.
