Twin giant pandas celebrate second birthday in Austria

The other three offspring of the panda couple, Fu Long, Fu Hu and Fu Bao, which mean lucky Dragon, Tiger, and Leopard respectively, were returned to China after two years old, an age the cubs in the wild should leave their mother.

Since the twins are still with the mother, the zoo currently has no plan to find a stepfather for the cubs.

"We hope that after the twins have left soon we will get a new male and we also hope Yang Yang will have other offspring in the future," the panda keeper said.

The giant pandas are the most famous symbol of the Schonbrunn Zoo which attracts a large number of visitors every year.
