The white-faced saki (Pithecia pithecia), is a species of New World saki monkey. The small bodied neotropical primate can be found in Brazil, French Guiana, Guyana, Suriname, and Venezuela.

Typical life expectancy is around 14 years in its natural habitat, although individuals have been recorded to live up to 36 years in captivity. The white faced saki is active in the day and sleeps highly elevated (15–20 m (49–66 ft)) in trees with many leaves to shelter from weather and flying predators.
Pairs of white-faced saki only breed once a year, but do not breed seasonally. Estimated typical breeding season is through August and September, but white-faced sakis have been observed breeding in March, April, and June. Breedings are typically not private and are sometimes even done with other group members watching. Regardless of when or how reproduction occurs, a... Wikipedia →

Likely
About 60% of wildlife watchers report a White-faced Saki sighting in Brownsberg Nature Park on a given day, based on 22 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 2nd most-seen of the 5 mammals we can rate there. Over three days the chance rises to about 90%, and over a week to over 90%, if each day is a fresh chance.
January, April and July
In those months about 70% of wildlife watchers report a White-faced Saki in Brownsberg Nature Park on a given day, against about 10% in February, the lowest month. June and August–September have too few records to rate.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most White-faced Saki sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Brownsberg Nature Park, in our data
Brownsberg Nature Park is the only park on Wallace's Line with enough records to rate White-faced Saki sightings: about 60% of wildlife watchers there report one on a given day.
Same order: Primates
The closest relatives of the White-faced Saki that you can see in Brownsberg Nature Park (order Primates) are Guianan Red Howler Monkey (about 60%) and chestnut weeper capuchin (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the White-faced Saki is recorded against all the mammals logged in Brownsberg Nature Park (22 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.
