In 3 days ~80% 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 →

GBIF citizen-science records
It is estimated from how often the Collins' Squirrel Monkey is recorded against all the mammals logged in São Luís (18 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.
