Zoo officials said this cub's cries sound strong, however. They plan to name it Dec. 24.
For now, however, there's a glow of amazement after "hoping and hoping and hoping for all these years," said Marty Dearie, another zoo panda keeper. There are only a few hundred pandas in captivity and about 1,600 left in the wild.
"We're excited and in disbelief all at the same time," Dearie said.
