Habitat
This species inhabits tropical rainforests in southeastern Peru and northern Bolivia. They prefer primary and secondary forests with dense vegetation and are often found in the middle canopy levels. Their terrain includes lowland areas up to about 500 meters elevation.
Diet
Ollala brothers' titi monkeys primarily eat fruits such as figs and berries, supplemented with leaves, insects, and seeds. They forage in small groups during the early morning and late afternoon, using their agile movements to access food in the trees. Feeding behavior involves careful selection to avoid toxic plants.
Behavior
They live in small, monogamous family groups of 2-7 individuals, typically a mated pair with their offspring, and maintain territories through loud, whistling calls. These monkeys are diurnal and arboreal, spending most of their time in trees and being most active during dawn and dusk. They exhibit strong pair bonding and cooperative care of young, with both parents involved in defense and rearing.
Conservation Status
The IUCN classifies the Ollala brothers' titi as Vulnerable due to habitat loss from deforestation and agriculture. Population trends show a decline, with major threats including fragmentation of rainforest habitats.
