(video: Giant Panda - Live Web Cam at Zoo)
National Zoo, in Washington D.C. says staff can hear the cub but have not yet seen it as Mei has built a substantial nest in her den. They say, "For now, the only way animal care staff will monitor the cub is using the web cams. Our goal is for Mei Xiang to raise this cub naturally."
This is Mei Xiang and Tian Tian’s second cub born as the result of artificial insemination. The chances of Mei Xiang conceiving a cub after five consecutive pseudopregnancies since 2007 was estimated to be less than 10 percent.
The female panda has been spending almost all her time in her den so keepers and volunteers have monitored her 24 hours-a-day via the panda cams from inside the David M. Rubenstein Family Giant Panda Habitat.
The new mother will most likely not come out of her den, eat, or drink, for at least a week.
