Likely
About 40% of wildlife watchers report a White-tailed Titi sighting in Yasuní National Park on a given day, based on 67 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 5th most-seen of the 33 mammals we can rate there. Over three days the chance rises to about 70%, and over a week to over 90%, if each day is a fresh chance.
December
In that month about 50% of wildlife watchers report a White-tailed Titi in Yasuní National Park on a given day, against about 20% in April and May, the lowest months.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most White-tailed Titi sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 2 parks where we can rate White-tailed Titi sightings, Yasuní National Park has the highest daily chance: about 40%. Next come Cuyabeno Wildlife Reserve (Ecuador, about 30%).
GBIF citizen-science records
It is estimated from how often the White-tailed Titi is recorded against all the mammals logged in Yasuní National Park (67 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.
