Panda born at Washington's National Zoo



Washington (CNN) -- There's a new panda in the National Zoo.

Officials at the Smithsonian's National Zoo confirmed the arrival of a cub on Friday for Mei Xiang following a quick labor.

DC's new celebrity resident was about the size of a butter stick and zoo officials said it appeared to be doing well, as was mom, who was cradling it in her den.

"This is a very delicate time for us. We're still on the lookout for a possible second cub," the zoo's director, Dennis Kelly, said at a news conference.

There was a 50% chance of a twin being born later Friday or early on Saturday.

A healthy little panda would be extra special because the female cub that Mei Xiang delivered nearly a year ago died within days. A lack of oxygen due to underdeveloped lungs was determined as the cause.

Zoo officials said they were pleased and hopeful things would work out this time, and they even brought in an expert from China to help out.

"After our last experience, and this is such a small cub, I am not going to relax," Kelly said. "We're gong to be tense for the next two or three months. We have high hopes."

It will take two to three weeks to know the sex of the cub and zoo officials won't name it for 100 days, following Chinese tradition.

Conceived through artificial insemination, it was the third pregnancy for Mei Xiang, 15. The National Zoo says the cub's father is either their own Tian Tian, 15, or the San Diego Zoo's Gao Gao, who is about 23.
