Hainan Gibbons are the worlds rarest primate, so conservationists are thrilled with the discovery of a 5th breeding pair. These agile animals are monogamous, and mated pairs sing together at dawn to strengthen their bond.
The new pair were discovered after locals heard their song in a part of the forest away from the rest of the (small) population. There are just over 30 Hainan Gibbons at last count.

The females are gold whilst males are black.
