The world’s first pigeon pair of Francois’ langur babies were introduced to the public at Changlong Wildlife Zoo in Guangzhou City, south China's Guangdong Province. /Chinanews Photo

It’s rare for primates to deliver two babies to the world within 24 hours, not to mention a pigeon pair. The langurs were born on April 19 and 20. /Chinanews Photo

 The newborns are covered in golden fur, but they’ll turn all black like their mother within two to three months. /Chinanews Photo

 Francois’ langurs are under first-class state protection in China and are listed as endangered by the International Union for Conservation of Nature and Natural Resources. /Chinanews Photo
