Habitat
They primarily inhabit tropical rainforests and riverine forests in northern South America, including Guyana, Suriname, French Guiana, and northern Brazil. These monkeys prefer the dense canopy of lowland forests up to about 1,000 meters elevation, where they can move easily among trees and access food sources.
Diet
Guyanan red howlers mainly eat leaves, fruits, and flowers, with a preference for nutrient-rich young leaves to supplement their diet. They feed primarily in the early morning and late afternoon, spending several hours a day foraging in the treetops to avoid ground predators.
Behavior
They live in social troops of 5-15 individuals, typically led by a dominant male, and are diurnal with most activity occurring in the early morning and evening. These monkeys are highly territorial, using loud, echoing howls to communicate and defend their home range, which can span several hectares. They spend much of their time resting and grooming to conserve energy due to their leaf-based diet.
Conservation Status
The IUCN classifies the Guyanan red howler as Vulnerable due to habitat loss from deforestation and mining activities, with populations declining overall.
