Habitat
This species primarily inhabits the Atlantic Forest in southeastern Brazil, favoring lowland and submontane tropical rainforests with dense vegetation. They prefer areas near rivers and coastal regions, avoiding open or heavily disturbed areas due to their need for canopy cover.
Diet
Coastal black-handed titis mainly eat fruits, supplemented by insects, leaves, and occasionally seeds. They forage in the upper canopy during the early morning and late afternoon, using their dexterous hands to pluck food items. Their feeding behavior involves moving slowly through branches to minimize disturbance.
Behavior
These monkeys form monogamous pairs that defend shared territories with vocal calls and chases. They are diurnal, spending most of their time in the trees, and exhibit strong pair bonding with mutual grooming. Family groups, consisting of parents and offspring, travel together and communicate through a variety of whistles and trills.
Conservation Status
The IUCN lists the coastal black-handed titi as Vulnerable due to habitat loss from deforestation and fragmentation. Population trends are declining, with major threats including agriculture expansion and urbanization in their Atlantic Forest range.
