On Sunday, at 9:17 a.m. ET, panda keepers at Smithonian's National Zoo heard distressed noises coming from Mei Xiang, the female giant panda. On the Panda Cam, zookeepers saw that her week-old cub was no longer moving.
A team of zookeepers retrieved the cub from the den and found the baby was not breathing and did not have a heart beat. They performed CPR, but veterinarians were unable to revive the cub.
Pamela Baker-Masson, associate director of communications for the zoo, said the cub, which did not yet have a name, showed no apparent signs of trauma or disease. It weighed just under 4 ounces. A necropsy will be performed to determine the cause of death.
The NewsHour will have more on this story later this week as more details are released.
