Habitat
This species primarily inhabits tropical rainforests in the Amazon basin, preferring areas with dense vegetation and proximity to rivers in countries like Brazil, Peru, and Colombia. They are arboreal, living in the understory and canopy layers of mature forests up to about 500 meters elevation.
Diet
Chestnut-bellied titis mainly eat fruits, leaves, and insects, with a preference for ripe fruits from various trees. They forage in small groups during the day, often in the early morning and late afternoon, using their dexterous hands to pluck food items.
Behavior
These monkeys are highly social, living in monogamous pairs or small family groups of up to five individuals, and they maintain strong pair bonds with mutual grooming. They are territorial, marking their areas with vocalizations and defending them from intruders, and they are primarily diurnal with agile, leaping movements through trees. Activity peaks in the early morning and evening, and they communicate with a variety of calls.
Conservation Status
The IUCN classifies the Chestnut-bellied titi as Vulnerable due to habitat loss from deforestation and agriculture, with populations declining rapidly in recent decades.
