The giant panda cub born to much excitement at the Smithsonian National Zoological Park in Washington, D.C., last weekend was found dead Sunday morning.
The Associated Press reports panda-keepers were alerted by sounds of distress from the cub's mother, Mei Xiang, but it was too late. The cause of death is not yet known, but zoo officials are planning a press conference at 1 p.m. ET.
On its Facebook page, the National Zoo posted this statement:
We are broken-hearted to share that we have lost our little giant panda cub. Panda keepers and volunteers heard Mei Xiang make a distress vocalization at 9:17 a.m. and let the veterinarian staff know immediately. They turned off the panda cam and were able to safely retrieve the cub for an evaluation at 10:22 a.m., which we only do in situations of gravest concern. The veterinarians immediately performed CPR and other life-saving measures, but sadly the cub was unresponsive. We'll have more updates as we learn more, but right now we know is that the cub weighed just under 100 grams and that there was no outward sign of trauma or infection. We'll share information with you as we learn more.
And we, too, will share more information as it comes in.
