The Kloss’s gibbon Hylobates klossii, also known as the Mentawai gibbon or bilou by locals, is a small, agile primate with dark smoky grey fur and an ethereal song that resonates and echoes throughout the forests of the Mentawai Islands. These gibbons are known for their intricate vocalisations, with both males and females producing unique solo songs. Their haunting melodies play an essential role in marking territory and strengthening social bonds.

Classified as Endangered by the IUCN, Kloss’s gibbons face a relentless barrage of threats, including habitat destruction for logging and palm oil plantations, poaching for the illegal pet trade, and human encroachment. With populations declining by 50% in the past 45 years, immediate action is needed to save this unique species. Fight for their survival with indigenous-led conservation efforts and use your wallet as a weapon—boycott palm oil and support sustainable agroecology. #BoycottPalmOil #Boycott4Wildlife
