Habitat
Tonkean monkeys primarily inhabit the tropical rainforests and montane forests of central Sulawesi, Indonesia, at elevations up to 2,000 meters. They prefer dense vegetation for cover and are often found near rivers or in areas with abundant fruit trees. This species avoids open areas, relying on forested terrain for foraging and shelter.
Diet
Tonkean monkeys are omnivorous, feeding mainly on fruits, leaves, and seeds, with insects and small invertebrates making up a significant portion of their diet. They forage in groups during the day, using their hands to manipulate food, and often climb trees to access ripe fruits. Feeding peaks in the early morning and late afternoon when food resources are most abundant.
Behavior
Tonkean monkeys live in multi-male, multi-female troops of 15-30 individuals, exhibiting a complex social hierarchy with frequent grooming and alliances. They are diurnal and arboreal, spending most of their time in trees, but will descend to the ground for food or water. These monkeys are known for their vocal communications, including alarm calls, and can be territorial, defending their home ranges from neighboring troops.
Conservation Status
The IUCN lists the Tonkean monkey as Vulnerable due to habitat loss from deforestation and hunting. Population trends are decreasing, with major threats including agricultural expansion and human encroachment in Sulawesi.
