On September 29, an infant white-cheeked gibbon was born at Poland’s Zoo Wroclaw. The baby is the child of Xian and Carusa and is believed to be a male. The population of white-cheeked gibbons in the wild is declining at an alarming pace. Only 150-160 individuals have been counted in nature. Zoos are becoming their only chance for their survival. Carusa and Xian are the only pair of white-cheeked gibbons in Poland. Just over 200 in zoos around the world have them in care.
