The Napo saki (Pithecia napensis), also known as the Napo monk saki, is a species of saki monkey, a type of New World monkey. Its range includes parts of eastern Ecuador and northern Peru. The name is derived from the Napo River in its locality. This species was originally described by Lönnberg as the subspecies Pithecia monachus napensis and has been treated as a synonym of P. monachus monachus. Hershkovitz retained it under P. monachus in 1987, but it was raised to full species status in 2014. Wikipedia →

Possible
About 30% of wildlife watchers report a Napo Saki sighting in Yasuní National Park on a given day, based on 48 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 11th 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.
February and June–July
In those months about 40% of wildlife watchers report a Napo Saki in Yasuní National Park on a given day, against under 5% in August and October, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Napo Saki 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 Napo Saki sightings: about 30% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Napo Saki is recorded against all the mammals logged in Yasuní National Park (48 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.
