About the Black Howler

The black howler (Alouatta caraya) or black-and-gold howler, is among the largest New World monkeys and a member of the Alouatta genus. The black howler is distributed in areas of South America such as Paraguay, southern Brazil, eastern Bolivia, northern Argentina, and Uruguay. This species is sexually dimorphic, with adult males having entirely black fur and adult females and babies of both sexes having an overall golden colouring; which emphasizes black-and-gold in the name. The IUCN Red List has classed the black howler as Near Threatened as a result of a recent population reduction due to a variety of human-caused factors.

The black howler is one of nine species of the Alouatta genus that have been identified and is in the Atelidae family. Because of this species' sexual dimorphism, the taxon for the black howler has been distinguished. Alouatta caraya
