The common woolly monkey, brown woolly monkey, or Humboldt's woolly monkey (Lagothrix lagothricha) is a woolly monkey from Colombia, Ecuador, Peru, Bolivia, Brazil, and Venezuela. It lives in groups of two to 70 individuals, usually splitting the group into smaller subgroups when active.
The taxonomy of the common woolly monkey is still debated. Later, an analysis of craniodental morphology suggested a move of all sub-species to the species level and also led to the yellow-tailed woolly monkey (formerly Lagothrix flavicauda) being moved to a monotypic genus Oreonax. Genetic analyses also identify distinct groups, but different groupings from morphological and molecular data continue to make this a difficult issue that might be addressed with larger data sets. A 2014 study found the genus Lagothrix to comprise only two species: L. lagothrica and L. flavicauda, with L. lagothrica containing five subspecies; the results of this study have been followed by the American Society of Mammalogists and the IUCN Red List...

Likely
About 40% of wildlife watchers report a Common Woolly Monkey sighting in Sierra de la Macarena National Park on a given day, based on 36 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 4th most-seen of the 6 mammals we can rate there. Over three days the chance rises to about 80%, and over a week to over 90%, if each day is a fresh chance.
December

GBIF citizen-science records
It is estimated from how often the Common Woolly Monkey is recorded against all the mammals logged in Sierra de la Macarena National Park (36 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
