Giant Pandas Turn 2 at Zoo Atlanta; Only Living Twins in U.S.

The only surviving giant panda twins ever born in the U.S. are celebrating their second birthday.

Zoo Atlanta officials said Mei Lun and Mei Huan turned 2 on Wednesday and were given special treats in their habitats. They say the pair will be treated to ice cakes during a second celebration Saturday.

The pandas were born two minutes apart at the Atlanta zoo.

According to the zoo's website, the twins are the fourth and fifth offspring of giant panda pair Lun Lun and Yang Yang, and are the only surviving pair of giant panda twins ever born in the U.S.

The website notes that the twins' older siblings, 8-year-old male Mei Lan, 6-year-old male Xi Lan, and 4-year-old female Po, live at China's Chengdu Research Base of Giant Panda Breeding.
