The brown tinamou (Crypturellus obsoletus) is a brownish ground bird found in humid lowland and montane forest in tropical and subtropical South America. All tinamous are usually treated in a single family (Tinamidae) and, contrary to traditional classifications, they are embedded within the group known as ratites, most closely related to the extinct moa of New Zealand. However, unlike ratites (ostriches, rheas, moa, kiwis, emus, cassowaries & elephantbirds), tinamous are capable of flight, although in general, they are not strong fliers. Different ratite lineages evolved separately from ancient flying birds, and tinamous are thought to most closely resemble these ancestral ratites.
Its distribution is highly disjunct and the subspecies, which quite probably represent more than one species, are distributed as follows: C. o. obsoletus, the nominate race, occurs in the Atlantic forest in southeastern Brazil, eastern Paraguay and Misiones, Argentina.
C. o. griseiventris occurs throughout the valley of Rio Tapajós, Brazil; southwestern Pará, southeastern Amazonas, and central Mato Grosso. C. o. hypochraceus occurs in upper Rio Madeira valley in central... Wikipedia →

With luck
About 10% of wildlife watchers report a Brown Tinamou sighting in Iguazú National Park on a given day, based on 594 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 103rd most-seen of the 343 birds we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
August
In that month about 20% of wildlife watchers report a Brown Tinamou in Iguazú National Park on a given day, against about 10% in September to July, the lowest months. That is one of Iguazú National Park's driest months, with about 90 mm of rain against 240 mm in October.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Brown Tinamou sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
4th of 8
Of the 8 parks where we can rate Brown Tinamou sightings, Iguazú National Park ranks 4th at about 10%. The best odds are in Amboró National Park (Bolivia, about 50%), Serra dos Órgãos National Park (Brazil, about 40%) and Itatiaia National Park (Brazil, about 20%).
GBIF citizen-science records
It is estimated from how often the Brown Tinamou is recorded against all the birds logged in Iguazú National Park (594 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.
