Northern brown howler

South America


Alouatta guariba guariba


The main threats for species survival include high susceptibility to yellow fever, predation due to its meat, and habitat loss due to agriculture, cattle grazing, and logging.

The Northern Howler Monkey, also called ‘baboon’ in Belize, exclusively inhabits the South American rainforests. At almost 36 inches in height when standing, it is considered as one of the biggest primates in the Neo-tropics.

This diurnal, arboreal primate only has fruits, flowers, and leaves for its diet, travelling in groups from tree to tree in search for food. Its prehensile tail is appropriate for grasping firmly from branches to branches. Males are black-coloured while females are brown-hued.
