With luck
About 10% of wildlife watchers report a Cinereous Tinamou sighting in Cuyabeno Wildlife Reserve on a given day, based on 66 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 109th most-seen of the 328 birds we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
March and June
In those months about 20% of wildlife watchers report a Cinereous Tinamou in Cuyabeno Wildlife Reserve on a given day, against under 5% in February and November, the lowest months.
Between 6 and 9 am
Across all the parks we cover, that three-hour window holds the most Cinereous Tinamou sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.

Of the 8 parks where we can rate Cinereous Tinamou sightings, Cuyabeno Wildlife Reserve ranks 6th at about 10%. The best odds are in Sierra de la Macarena National Park (Colombia, about 30%), Manu National Park (Peru, about 30%) and Yasuní National Park (Ecuador, about 20%).
GBIF citizen-science records
It is estimated from how often the Cinereous Tinamou is recorded against all the birds logged in Cuyabeno Wildlife Reserve (66 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.
