The National Zoo’s beloved bears are set to leave this month, while the loan agreement for the country’s only other pandas, at Zoo Atlanta, is expiring next year.

Some of the last giant pandas in the United States are heading back to China.

The National Zoo announced last week that its three pandas — Mei Xiang, Tian Tian and their 3-year-old male cub, Xiao Qi Ji — will return to China by Nov. 15, earlier than expected.

Panda fans have been flocking to say goodbye to the black-and-white bears, who have long been one of the zoo’s main attractions.
