Bolivia is a South American landlocked country; known as the most isolated country on the continent, around 60% of its population comprises Indigenous Peoples[1].
The nation is also home to 25 species of New-World monkeys, though just two are endemic to it: the Beni titi monkey (Plecturocebus modestus) and the Ollala Brothers’ titi (Plecturocebus olallae).
The latter, an endangered species, is known for its energy-conserving behavior—during drier seasons, it will move around less to get food, and, instead of scouring for particular fruits as it usually does, it will settle for consuming more common foods, such as seeds and fungi[2].
This efficient dietetic strategy helps the Ollala Brothers’ titi to suitably live in the Llanos de Moxos wetland of the Amazon Rainforest.
Other common monkey species in Bolivia include the saddleback tamarin (Leontocebus fuscicollis), the Bolivian red howler monkey (Alouatta sara), and the black-headed night monkey (Aotus nigriceps).
Bolivian Monkeys
