A conservation center has been caring for endangered gibbons for 50 years. The center now has around 40 gibbons from five different species. These primates are known for making loud noises, which can be heard from far away.

Their vocalizations are quite varied, sounding like different animals or even emergency signals. The center has become well-known globally for its work with gibbons. Further information about the center and its work with these rare animals is available from the original source.
