Possible
About 20% of wildlife watchers report a Blond Titi Monkey sighting in Chapada Diamantina National Park on a given day, based on 8 verified sightings from GBIF citizen-science data from 2019 to 2026. 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.
May, July and November
In those months about 40% of wildlife watchers report a Blond Titi Monkey in Chapada Diamantina National Park on a given day, against under 5% in March–April, June, August–October and December, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Blond Titi 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 Chapada Diamantina National Park, in our data
Chapada Diamantina National Park is the only park on Wallace's Line with enough records to rate Blond Titi 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 Blond Titi Monkey is recorded against all the mammals logged in Chapada Diamantina National Park (8 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.
