Status
The species is common throughout its range but faces potential decline due to habitat loss.

Habitat
Bolivian gray titi monkeys occupy rain forest habitats, where they live an arboreal lifestyle among the trees.

Niche
Bolivian gray titi monkeys feed on the fruit and leaves they find in the trees of their home, with insects composing a small percentage of their diet.

Life History
