Habitat
Black howlers primarily inhabit tropical rainforests, gallery forests, and semi-deciduous woodlands in South America, including regions of Argentina, Bolivia, Brazil, and Paraguay. They prefer areas with dense canopy cover for movement and protection, often near rivers or in areas with abundant fruit trees.
Diet
Black howlers mainly eat leaves, fruits, and flowers, with a strong preference for mature leaves that make up the bulk of their diet for energy and nutrients. They are folivorous and spend several hours each day foraging in the treetops, typically feeding during the early morning and late afternoon.
Behavior
Black howlers live in social groups of 5 to 15 individuals, typically led by a dominant male, and are highly territorial with loud vocalizations that can be heard up to 5 km away to ward off intruders. They are diurnal and arboreal, spending most of their time in trees resting or grooming, and exhibit strong bonding behaviors like mutual grooming within the group.
Conservation Status
The IUCN status of the black howler is Vulnerable, with population trends decreasing due to habitat loss from deforestation and hunting pressure. Major threats include agricultural expansion and fragmentation of their forest habitats.
