Scientific Summary

GBIF Taxonomic Backbone & Wikipedia Registry Profile

Activity patterns. In the study at Paranaita, the daily activity budget over the year was 587 % resting, 20 % feeding, 14 - 2 % traveling, 4 % moving around in trees, and 3 - 1 % engaged in social interactions and other activities. Spix’s Howlers tend to retire to their sleeping trees earlier in the wet season. Most sleeping trees had a canopy covered with tangles of vines, where the individuals could be well hidden.
Biology & Conservation

Ecologically, the conservation status of Spix's red-handed howler monkey is officially designated as Vulnerable. Current field registries estimate a global population composed of an unquantified number of individuals, making habitat preservation critical to maintaining their wild populations.

It is typically endemic to forest, wetland, freshwater, mountain, showing great physiological synergy with its surroundings. In terms of dietary preferences, it relies primarily on a diet of fresh fruits, young leaves, seeds, flowers, and forest insects. It exhibits specialized adaptations centered around a diurnal activity pattern, optimizing its energy conservation and interactions within its native ecosystem. The species has a typical natural lifespan of approximately 25 years, allowing it to adapt and mature through structured generational cycles.

Ongoing biological monitoring and ecological advocacy emphasize the importance of protecting this species. The stability of its food chain and the prevention of fragmentation in its primary range are vital for the continued survival of Spix's red-handed howler monkey.
