Habitat
Spix's red-handed howler inhabits the tropical rainforests of the Amazon Basin, primarily in Brazil, including areas with dense canopy and riverine forests. They prefer lowland forests with abundant trees for foraging and resting, avoiding open or disturbed areas. Geographic range is limited to specific regions in the eastern Amazon.
Diet
This species primarily eats leaves, fruits, and flowers, with a preference for mature leaves that make up the bulk of their diet. They feed during the day, spending several hours in the canopy browsing for food, and occasionally consume insects or buds for additional nutrients. Feeding behavior includes selective leaf-picking to avoid toxic plants.
Behavior
Spix's red-handed howler lives in social troops of 5-15 individuals, typically led by a dominant male, with complex vocalizations used for territory defense and communication. They are diurnal and arboreal, spending most of their time in trees, and exhibit territorial behavior by howling at dawn and dusk to ward off intruders. Notable behaviors include resting for long periods to digest their leafy diet and grooming each other to maintain social bonds.
Conservation Status
Spix's red-handed howler is classified as Vulnerable by the IUCN due to habitat loss from deforestation and fragmentation. Major threats include hunting and agricultural expansion, with populations showing a decreasing trend.
