March 16 is National Panda day.
Pandas are one of the most popular animals for visitors at zoos around the world.
About 100 zoos across the world have pandas like these at the National Zoo in Washington, DC.
The animals are members of the bear family and native to China.
But their habitats are shrinking and less than 2,000 exist in the wild.
Breeding pandas in captivity is also a challenge, which keeps the animals on the vulnerable species list.
