The Marañón white-fronted capuchin (Cebus yuracus) also or known as Peruvian white-fronted capuchin or Andean white-fronted capuchin is a species of gracile capuchin monkey from the upper Amazon Basin. It had been regarded as synonymous with the shock-headed capuchin (C. cuscinus), which was then considered a subspecies of Humboldt's white-fronted capuchin, but it was classified as a separate species by Mittermeier and Rylands based on genetic studies by Boubli.
The Marañón white-fronted capuchin lives in wet forests of the upper Amazon basin in southern Colombia, eastern Ecuador, northeastern Peru and likely eastern Brazil. Males have a head and body length of about 43 cm (17 in) with a tail length of about 47 cm (19 in). Females have a head and body length about 37 cm (15 in) with a tail length of about 45 cm (18 in).
Marañón white-fronted capuchins sometimes formed mixed groups with the Ecuadorian squirrel monkey. Wikipedia →

Likely
About 40% of wildlife watchers report a Marañón white-fronted capuchin sighting in Cuyabeno Wildlife Reserve on a given day, based on 50 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 8th most-seen of the 19 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.
February
In that month about 70% of wildlife watchers report a Marañón white-fronted capuchin in Cuyabeno Wildlife Reserve on a given day, against under 5% in December, the lowest month.
Between 3 and 6 pm
Across all the parks we cover, that three-hour window holds the most Marañón white-fronted capuchin 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 3 parks where we can rate Marañón white-fronted capuchin sightings, Cuyabeno Wildlife Reserve has the highest daily chance: about 40%. Next come Yasuní National Park (Ecuador, about 30%) and Podocarpus National Park (Ecuador, about 30%).
GBIF citizen-science records
It is estimated from how often the Marañón white-fronted capuchin is recorded against all the mammals logged in Cuyabeno Wildlife Reserve (50 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.
