The golden-mantled tamarin (Leontocebus tripartitus) is a tamarin species from South America. It is found in Ecuador and Peru, specifically in the upper Amazon (lowland), east of the Andes in Ecuador, and Northeast Peru; between the Rio Curaray and Rio Napo in Peru.
There has been some debate over the placing of L. tripartitus. In field observations in South America, scientists compared feeding habits and heights between golden-mantled tamarins (L. tripartitus) and brown-mantled tamarins (Leontocebus fuscicollis) and they concluded that patterns of height were very similar to those observed in L. fuscicollis. The similarity and the lack of evidence for sympatry with either L. fuscicollis or the black-mantled tamarin (Leontocebus nigricollis) led to the suggestion that L. tripartitus should be reconsidered as a subspecies of L. fuscicollis rather than a species on its own; alternatively, other subspecies of L. fuscicollis should be raised in taxonomic rank. It is currently considered a separate species within the saddle-back tamarin genus Leontocebus.
This tamarin measures 218–240 mm from the tip of the nose to the beginning of the tail... Wikipedia →

Possible
About 30% of wildlife watchers report a Golden-mantled Tamarin sighting in Yasuní National Park on a given day, based on 66 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 6th 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.
June–September and November–January
In those months about 40% of wildlife watchers report a Golden-mantled Tamarin in Yasuní National Park on a given day, against about 10% in March, the lowest month.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Golden-mantled Tamarin sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Yasuní National Park, in our data
Yasuní National Park is the only park on Wallace's Line with enough records to rate Golden-mantled Tamarin sightings: about 30% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Golden-mantled Tamarin is recorded against all the mammals logged in Yasuní National Park (66 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.
