How does the habitat of *Oreonax flavicauda* differ from *Lagothrix lagotricha*?
*O. flavicauda* is confined to high-elevation cloud forests, while *L. lagotricha* inhabits lowlands.
The two primates occupy distinct ecological niches related to elevation. The common woolly monkey, *Lagothrix lagotricha*, typically inhabits the tropical lowland rainforests, sometimes extending into flooded areas. In sharp contrast, the Yellow-tailed woolly monkey, *Oreonax flavicauda*, is endemic to Peru and is specifically confined to humid montane or cloud forests located at much higher elevations. This environmental difference is theorized to influence the physical adaptations, such as the denser fur of *O. flavicauda*, which provides better insulation against the consistently cooler and damper conditions found in those higher altitude environments.
