The eared pygmy tyrant (Myiornis auricularis) is a species of bird in the family Tyrannidae, the tyrant flycatchers. It is found in Argentina, Brazil, and Paraguay. The Clements taxonomy includes a potential third subspecies, "Eared Pygmy-Tyrant (Pernambuco)", as "Myiornis auricularis [undescribed form]". One author has treated the white-bellied pygmy tyrant (M. albiventris) as a subspecies of the eared pygmy tyrant but major taxonomic systems retain it as a full species.
The eared pygmy tyrant's taxonomy has undergone other changes as well. Genus Platyrhynchos eventually was limited to some Old World species and then lost altogether, and Euscarthmus was eventually limited to a few New World species. The eared pygmy tyrant landed in Myiornis, which several authors have suggested should be merged into genus Hemitriccus... Wikipedia →

Possible
About 20% of wildlife watchers report an Eared Pygmy-Tyrant sighting in Iguazú National Park on a given day, based on 1,111 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 57th most-seen of the 343 birds we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
May and July–September
In those months about 30% of wildlife watchers report an Eared Pygmy-Tyrant in Iguazú National Park on a given day, against about 10% in December, the lowest month.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Eared Pygmy-Tyrant sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 6 parks where we can rate Eared Pygmy-Tyrant sightings, Iguazú National Park has the highest daily chance: about 20%. Next come Iguaçu National Park (Brazil, about 20%) and Itatiaia National Park (Brazil, about 20%).
Same family: Tyrannidae
The closest relatives of the Eared Pygmy-Tyrant that you can see in Iguazú National Park (family Tyrannidae, Tyrant Flycatchers) are Great Kiskadee (about 80%), Social Flycatcher (about 30%) and Boat-billed Flycatcher (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Eared Pygmy-Tyrant is recorded against all the birds logged in Iguazú National Park (1,111 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.
