Rare
Under 5% of wildlife watchers report a Drab-breasted Pygmy-Tyrant sighting in Iguaçu National Park on a given day, based on 29 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 264th most-seen of the 346 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Drab-breasted Pygmy-Tyrant in Iguaçu National Park on a given day, so our monthly data shows no clear season.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Drab-breasted Pygmy-Tyrant 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 4
Of the 4 parks where we can rate Drab-breasted Pygmy-Tyrant sightings, Iguaçu National Park ranks 4th at under 5%. The best odds are in Itatiaia National Park (Brazil, about 10%), Serra dos Órgãos National Park (Brazil, under 5%) and Iguazú National Park (Argentina, under 5%).
GBIF citizen-science records
It is estimated from how often the Drab-breasted Pygmy-Tyrant is recorded against all the birds logged in Iguaçu National Park (29 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.
