A gibbon gave birth to a cub at the Bawangling National Nature Reserve in the island province of Hainan.
The newborn has brought the number of gibbons to 20 in the tropical rain forest at the reserve. Both the young gibbon, which was born about 10 days ago, and its mother, are in good health.
The Hainan gibbon is among the most threatened primates in the world. And it has been listed as one of the world's 25 most endangered primate species.
