Tiny twin panda cubs were born to a 15-year-old giant panda named Lun Lun earlier this week at Zoo Atlanta, the first set of panda twins born in the United States in 26 years. The second cub was a surprise, after an earlier ultrasound seemed to indicate a solo cub.

"This is a success we share with all of our fellow zoological organizations working to understand and protect this iconic species, and we share our joy with our local community and with our colleagues in China,"said Zoo Atlanta President and CEO Raymond B. King. "Twins are an entirely new scenario for Lun Lun, Zoo Atlanta and our animal care teams, who will no doubt be extremely busy over the next few months."

The cubs are also the first giant pandas born in the US this year, and were the result of artificial insemination using sperm from a 15-year-old panda named Yang Yang, who is also housed at the zoo. Zoo Atlanta worked closely with panda caretakers and scientists from the Chengdu Research Base of Giant Panda Breeding, Lun Lun's birthplace.

The mortality rate among panda infants is high, so the next few weeks will be crucial, said Rebecca Snyder, curator of mammals at Zoo Atlanta. Fortunately, one of the cubs is heavier than average, weighing in at 145 grams. The other is about average, at 99 grams.

Twin births are not uncommon among pandas, but panda mothers have generally tended to favor one cub over the other, leaving the second to die. To protect both cubs, zookeepers and animal caretakers from the Arthur M. Blank Family Foundation Giant Panda Center are rotating the cubs in and out so that Lun Lun is only caring for one at a time during the first few months. The cubs, which will grow their famous black and white coats in about a week, were separated shortly after birth. Lun Lun and the cubs are also under 24-hour observation via a live video feed, as was the case during gestation.

Lun Lun was immediately protective, and is reluctant to give up either cub once she is holding it, Snyder said. Both cubs' diets have been supplemented with milk formula.

"She's keeping the cubs warm, and being a normal, good mom,"Snyder said of Lun Lun. "It's normal for her to want to hold on to her cub.

"The panda team is tired and a little stressed, but happy,"the statement said. "The next few days are especially critical. So please continue to keep us in your thoughts. We can use the good vibes!”

If all goes well, the panda cubs will be available for viewing at Zoo Atlanta in about four months. Zoo Atlanta, which received the International Conservation Award from the Association of Zoos and Aquariums last year, plans to follow the Chinese tradition of naming the cubs when they reach 100 days.

The global giant panda population is less than 2,000, with approximately 300 in captivity and 1,600 in the wild. Successful conservation of the species will be a challenge, but one that signifies ongoing cooperation and goodwill between China and the US, Snyder said.

"We certainly see giant pandas as ambassadors for both the species and for China, because they are so important culturally and historically. We see this as a great relationship builder between the two countries."
