Giant panda twins arrive in twos
Giant panda Meng Meng gave birth to a pair of female twins on May 23, while panda mom Ya Yun gave birth to a pigeon pair – one male, one female – on June 5.
Giant panda are a vulnerable species, with a low birth rate. The World Wildlife Fund estimates there are only 1,864 giant pandas living in the wild right now.
The younger twins are the first pigeon pair born this year, and the older twins are the first panda twins born in 2018.
Panda breeders working at the Chengdu Research Base of Giant Panda Breeding said all four panda babies are in good health.
