Miller's saki (Pithecia milleri), also known as Miller's monk saki, is a species of saki monkey, a type of New World monkey. Its range includes parts of southwestern Colombia, northeastern Ecuador, and perhaps adjacent areas in Peru. This species was originally described as a species by J. A. Allen, demoted to a subspecies of the monk saki (P. monachus) in 1987, and raised back to full species status in 2014. Confusion over the taxonomy of saki monkeys has arisen in part due to poorly labeled or mislabeled museum specimens. Males and females of this species, like those of other sakis, have differently colored pelage, with the females being more grayish in the face and overall, and the males a darker, grizzled black but with brown in the face and forearms.

Very likely
About 70% of wildlife watchers report a Miller's Saki sighting in Cuyabeno Wildlife Reserve on a given day, based on 113 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 2nd most-seen of the 19 mammals we can rate there. Over three days the chance rises to over 90%, if each day is a fresh chance.
July and November
In those months about 80% of wildlife watchers report a Miller's Saki in Cuyabeno Wildlife Reserve on a given day, against about 50% in December, the lowest month.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Miller's 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 Cuyabeno Wildlife Reserve, in our data
Cuyabeno Wildlife Reserve is the only park on Wallace's Line with enough records to rate Miller's Saki sightings: about 70% of wildlife watchers there report one on a given day.
Same family: Pitheciidae
The closest relatives of the Miller's Saki that you can see in Cuyabeno Wildlife Reserve (family Pitheciidae, Sakis, Titis, and Uakaris) are Lucifer Titi (about 40%) and White-tailed Titi (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Miller's Saki is recorded against all the mammals logged in Cuyabeno Wildlife Reserve (113 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.
