Look who’s having twins!
No, not Duchess Catherine, but this pair’s arrival is a landmark in its own right. Giant panda Lun Lun and her partner, Yang Yang, both 15-years-old and residing at Georgia’s Zoo Atlanta, welcomed a pair of tiny twins on Monday. The births are the first for panda twins in the U.S. since 1987.
“This is a success we share with all our fellow zoological organizations working to understand and protect this iconic species,” Raymond B. King, president and CEO of Zoo Atlanta, said on its website. “And we share our joy with our local community and with our colleagues in China.”
The cubs, who will not be named until their 100th day in accordance with Chinese tradition, will be put on display in late fall, where they will join their brothers, 4-year-old Xi Lan and 2-year-old Po. Their sex has yet to be determined.
