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 →

Possible
About 30% of wildlife watchers report a Marañón white-fronted capuchin sighting in Yasuní National Park on a given day, based on 79 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 7th most-seen of the 33 mammals we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
September
In that month about 50% of wildlife watchers report a Marañón white-fronted capuchin in Yasuní National Park on a given day, against about 20% in May and December–January, the lowest months.
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.
2nd of 3
Of the 3 parks where we can rate Marañón white-fronted capuchin sightings, Yasuní National Park ranks 2nd at about 30%. The best odds are in Cuyabeno Wildlife Reserve (Ecuador, about 40%).
GBIF citizen-science records
It is estimated from how often the Marañón white-fronted capuchin is recorded against all the mammals logged in Yasuní National Park (79 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.
