Watch Live Panda Birth Cam: Zoo Atlanta’s Lun Lun is Having Twins

ATLANTA, GA — Zoo Atlanta's giant panda, Lun Lun, is expecting twins, and you can join in the anticipation of what would be the first giant pandas born in captivity in the U.S. this year.

The zoo confirmed the pregnancy late last week, but on Tuesday, the zoo released the image of an ultrasound that reveals the presence of a second fetus. You can watch a live stream of the birth below.

A 24-hour birthwatch began on Monday. Lun Lun was artificially inseminated on March 28.

Lun Lun, who turns 19 on Thursday, Aug. 25, is the mother of the only pair of giant panda twins in the U.S., 3-year-olds Mei Lun and Mei Huan. While giant pandas give birth to twins approximately 50 percent of the time, wild giant panda mothers will typically care for only one cub.

The new cubs would be the sixth and seventh for Lun Lun and 18-year-old male Yang Yang. The pair’s first, second and third offspring, Mei Lan, Xi Lan and Po, now reside at the Chengdu Research Base of Giant Panda Breeding in China. Their fourth and fifth, 3-year-old females Mei Lun and Mei Huan, reside at Zoo Atlanta and are the only twin giant pandas in the U.S.
