The black-capped squirrel monkey (Saimiri boliviensis) is a species of New-World monkey native to the upper Amazon basin in Bolivia, western Brazil and eastern Peru. They weigh between 365 and 1,135 g (13 and 40 oz) and measure, from the head to the base of the tail, between 225 and 370 mm (9 and 15 in). The black-capped squirrel monkey is primarily tree-dwelling and is found in both native and plantation forests as well as some farmed areas near running water. Its diet is omnivorous and mostly consists of flowers, fruit, leaves, nuts, seeds, insects, arachnids, eggs and small vertebrates. It mostly lives in female-dominated troops of around 40 to 75 monkeys, with males having been observed to disperse to live in all-male troops after reaching sexual maturation.
The black-capped squirrel monkey displays sexual dimorphism, with males normally weighing between 550 and 1,135 g (19... Wikipedia →

Possible
About 20% of wildlife watchers report a Black-capped Squirrel Monkey sighting in Santa Cruz de la Sierra on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 4th most-seen of the 5 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.
July to October
In those months about 30% of wildlife watchers report a Black-capped Squirrel Monkey in Santa Cruz de la Sierra on a given day, against under 5% in May–June and November–March, the lowest months. Those are among Santa Cruz de la Sierra's driest months, with about 55 mm of rain a month against 170 mm in January.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Black-capped Squirrel Monkey 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 Santa Cruz de la Sierra, in our data
Santa Cruz de la Sierra is the only city on Wallace's Line with enough records to rate Black-capped Squirrel Monkey sightings: about 20% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Black-capped Squirrel Monkey is recorded against all the mammals logged in Santa Cruz de la Sierra (6 verified sightings), 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.
