Possible
About 30% of wildlife watchers report a White-tailed Titi sighting in Cuyabeno Wildlife Reserve on a given day, based on 13 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 13th most-seen of the 19 mammals we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
March and October
In those months about 40% of wildlife watchers report a White-tailed Titi in Cuyabeno Wildlife Reserve on a given day, against under 5% in February, April–May and November, 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.
2nd of 2
Of the 2 parks where we can rate White-tailed Titi sightings, Cuyabeno Wildlife Reserve ranks 2nd at about 30%. The best odds are in Yasuní National Park (Ecuador, about 40%).
Same family: Pitheciidae
The closest relatives of the White-tailed Titi that you can see in Cuyabeno Wildlife Reserve (family Pitheciidae, Sakis, Titis, and Uakaris) are Miller's Saki (about 70%) and Lucifer Titi (about 40%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the White-tailed Titi is recorded against all the mammals logged in Cuyabeno Wildlife Reserve (13 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.
