Sumatran Surili

Fascinating facts about the Sumatran Surili

• These langurs live in one-male groups with five to seven females, defending home ranges of 14-30 hectares that can stretch up to 950 meters in a single day. Overlap between neighboring groups is usually 20-30 percent, but in disturbed forests it can soar to 79 percent, forcing more frequent territorial clashes. The tight social unit and large daily travel distance highlight how habitat fragmentation pressures their social stability.
• From 2000 to 2012, the black-crested Sumatran langur lost an estimated 62% of its forest home.
• When a predator such as a Python snake or a crested serpent eagle appears, the harem male rushes forward, emitting loud cries and leaping to draw the threat away, sometimes pulling the attacker as far as 240 feet from the rest of the group.
