Habitat
Heck's monkey inhabits tropical rainforests and mangrove forests on the island of Sulawesi in Indonesia. They prefer areas with dense vegetation for cover and access to water sources, typically at elevations up to 2,000 meters. Their range is limited to specific forested regions, avoiding open or highly disturbed areas.
Diet
Heck's monkey primarily eats fruits, leaves, seeds, and insects, with a preference for figs and other ripe fruits. They forage in groups during the day, using their hands to manipulate food and cheek pouches to store items while feeding. Feeding peaks in the early morning and late afternoon when food sources are most abundant.
Behavior
Heck's monkey lives in multi-male, multi-female troops of 10-30 individuals, with a clear dominance hierarchy led by adult males. They are diurnal and arboreal, spending much of their time in trees but descending for water or food, and exhibit territorial behaviors like vocalizations and displays to defend their range. Notable behaviors include grooming to strengthen social bonds and playful interactions among juveniles.
Conservation Status
Heck's monkey is classified as Vulnerable by the IUCN due to habitat loss from deforestation and hunting. Population trends are decreasing, with major threats including agricultural expansion and the pet trade.
