With luck
About 10% of wildlife watchers report a Bearded Tachuri sighting in Iberá National Park on a given day, based on 80 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 184th most-seen of the 284 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
February–March, June and October
In those months about 10% of wildlife watchers report a Bearded Tachuri in Iberá National Park on a given day, against under 5% in April–May, July–September and November–January, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Bearded Tachuri sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 2 parks where we can rate Bearded Tachuri sightings, Iberá National Park ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Emas National Park (Brazil, about 10%).

GBIF citizen-science records
It is estimated from how often the Bearded Tachuri is recorded against all the birds logged in Iberá National Park (80 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.
