Tonkean Macaque
A charismatic and rare primate, the black macaque is the soul of Malenge's forests.
- Local name: Monyet Malenge
- Scientific name: Macaca tonkeana
Tonkean Macaque are stocky, dark macaques endemic to Sulawesi and found in the Togeans on Malenge Island. They're recognizable by their short tails, pale cheek tufts, and bold behavior near fruiting trees. Troops move through forest edges and interior trails, foraging for fruits, seeds, and insects.

Where to see it
Most reliably seen on forest walks in Malenge's interior, especially early morning and late afternoon when troops are actively foraging. They favor forest edges and areas with fruiting trees, and their loud contact calls often reveal their location before you see them.
How to spot it
Listen for loud vocalizations and the sound of branches shaking as they move through the canopy. Scan fruiting trees at mid-canopy level — troops often gather where food is abundant. Look for dark shapes moving deliberately through the branches, sometimes pausing to watch you back.
Watching responsibly
- Stay at least 10 meters back — they're habituated to human presence but still wild.
- Never feed them or expose food — it alters natural foraging behavior.
- Move slowly and avoid prolonged direct eye contact, which they read as aggression.
- Don't block their path through the forest — let them pass freely.
- Carry out all trash — food waste attracts them to human areas.
Conservation
IUCN: Vulnerable (2025 update), vulnerable locally to habitat loss and pollution.
