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 60% of wildlife watchers report a Common Woolly Monkey sighting in Yasuní National Park on a given day, based on 251 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the most-seen of the 33 mammals we can rate there. Over three days the chance rises to about 90%, and over a week to over 90%, if each day is a fresh chance.
November
In that month about 80% of wildlife watchers report a Common Woolly Monkey in Yasuní National Park on a given day, against about 30% in August, the lowest month.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Common Woolly Monkey sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 5 parks where we can rate Common Woolly Monkey sightings, Yasuní National Park has the highest daily chance: about 60%. Next come Cuyabeno Wildlife Reserve (Ecuador, about 50%) and Sierra de la Macarena National Park (Colombia, about 40%). All parks ranked.
Same family: Atelidae
The closest relatives of the Common Woolly Monkey that you can see in Yasuní National Park (family Atelidae, Spider, Howler, and Woolly Monkeys) are Colombian Red Howler Monkey (about 50%) and Long-haired Spider Monkey (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Common Woolly Monkey is recorded against all the mammals logged in Yasuní National Park (251 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.
