Spix's black mantle tamarin, Leontocebus nigricollis nigricollis Graells's tamarin or Graells' black-mantle tamarin, Leontocebus nigricollis graellsi Hernandez-Camacho's black-mantle tamarin, Leontocebus nigricollis hernandezi
Graells's tamarin was previously considered to be a separate species. Predators of black-mantled tamarins include barred forest falcons. Wikipedia →

Possible
About 20% of wildlife watchers report a Black-mantled Tamarin sighting in Yasuní National Park on a given day, based on 25 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 16th most-seen of the 33 mammals we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
April, June and August–October
In those months about 30% of wildlife watchers report a Black-mantled Tamarin in Yasuní National Park on a given day, against under 5% in May and December, the lowest months.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Black-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.
2nd of 3
Of the 3 parks where we can rate Black-mantled Tamarin sightings, Yasuní National Park ranks 2nd at about 20%. The best odds are in Cuyabeno Wildlife Reserve (Ecuador, about 40%).
GBIF citizen-science records
It is estimated from how often the Black-mantled Tamarin is recorded against all the mammals logged in Yasuní National Park (25 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.
