Also, throughout their range they are called inhambu-preto. Cinereous tinamous have been around for many centuries. They are part of the oldest families of the world today and have fossils discovered dating back tens of millions of years. Their quick reflexes play a role in their ability to survive.
The cinereous tinamou was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He placed it with all the grouse like birds in the genus Tetrao and coined the binomial name Tetrao cinereus. Gmelin based his description on "Le tinamou cendré" from French Guiana that had been described in 1778 by the French polymath Georges-Louis Leclerc, Comte de Buffon in his Histoire Naturelle des Oiseaux. The cinereous tinamou is now placed with around... Wikipedia →

Possible
About 30% of wildlife watchers report a Cinereous Tinamou sighting in Sierra de la Macarena National Park on a given day, based on 298 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 24th most-seen of the 418 birds 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.
May and June
In those months about 40% of wildlife watchers report a Cinereous Tinamou in Sierra de la Macarena National Park on a given day, against about 20% in April and July–November, the lowest months. Those are among Sierra de la Macarena National Park's wettest months, with about 400 mm of rain a month against 95 mm in January.
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.
Yes
Of the 8 parks where we can rate Cinereous Tinamou sightings, Sierra de la Macarena National Park has the highest daily chance: about 30%. Next come Manu National Park (Peru, about 30%) and Yasuní National Park (Ecuador, about 20%).
Same genus: Crypturellus
The closest relatives of the Cinereous Tinamou that you can see in Sierra de la Macarena National Park (genus Crypturellus, Crypturellus Tinamous) are Little Tinamou (about 10%) and Undulated Tinamou (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Cinereous Tinamou is recorded against all the birds logged in Sierra de la Macarena National Park (298 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.
