In 3 days ~90% in a week >90%
Collins' squirrel monkey (Saimiri collinsii) is a species of squirrel monkey endemic to Brazil. It had been considered a subspecies of the common squirrel monkey (S. sciureus) until a genetic study by Jessica Lynch Alfaro et al. elevated it to species status.
Male Collins' squirrel monkeys have a head and body length of about 38 cm (15 in) with a 37.6 cm (14.8 in) tail. Females have a head and body length of about 27 cm (11 in) with a 41.3 cm (16.3 in) tail. Collins' squirrel monkeys eat palm fruits, legumes, insects, bird eggs and occasionally lizards. Wikipedia →

About 50% of wildlife watchers report a Collins' Squirrel Monkey sighting in Belém on a given day, based on 32 verified sightings from GBIF citizen-science data. It is the most-seen of the 6 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.

GBIF citizen-science records
It is estimated from how often the Collins' Squirrel Monkey is recorded against all the mammals logged in Belém (32 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.
