The black-headed night monkey (Aotus nigriceps) is a night monkey species from South America. It is found in Brazil, Bolivia and Peru. The A. nigriceps in Peru were notably inhabiting areas that were degraded, and often these areas were disturbed either by human activities or natural occurrences in the ecosystem.
