A giant panda lent to the United States by China and living at the National Zoo in Washington, D.C. l has given birth to a cub, zoo officials said Monday. The birth occurred at about 10:46 pm local time Sunday, according to the zoo’s chief veterinarian, Suzan Murray. During a press conference at the National Zoo on Monday, Dennis Kelly, Director of the Smithsonian National Zoo said, “We have pandas for research opportunities” and now that we have a cub, they will have even more to study. Mei Xiang, as the mom panda is called, “is cradling her cub closely, and she looks so tired,” Murray said in a statement.
