Eastern Grey Gibbon

The eastern grey gibbon, also called the northern grey gibbon and scientifically Hylobates funereus, is a primate of the gibbon family endemic to northeastern Borneo, found across Sabah, Sarawak and Brunei, from Sabah south to the Mahakam River and west to Baram in Sarawak. It was previously grouped with the western grey gibbon and southern grey gibbon as a single species, and the three can still interbreed where their ranges overlap, though they are now recognized as distinct species. It is listed as Endangered by the IUCN and included in CITES Appendix I, threatened by forest loss, wildfires linked to El Nino events, illegal hunting, and capture for the pet trade.
