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 →

Rare
Under 5% of wildlife watchers report an Eared Pygmy-Tyrant sighting in Chapada Diamantina National Park on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 258th most-seen of the 271 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.
June
In that month about 10% of wildlife watchers report an Eared Pygmy-Tyrant in Chapada Diamantina National Park on a given day, against under 5% in July to May, the lowest months. That is one of Chapada Diamantina National Park's driest months, with about 50 mm of rain against 180 mm in November.

GBIF citizen-science records
It is estimated from how often the Eared Pygmy-Tyrant is recorded against all the birds logged in Chapada Diamantina National Park (5 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.
