The ochre-lored flatbill (Tolmomyias flaviventris) or yellow-breasted flycatcher, is a passerine bird in the family Tyrannidae, the tyrant flycatchers. It is found in Bolivia, Brazil, Colombia, French Guiana, Guyana, Panama, Suriname, Trinidad and Tobago, and Venezuela.
The ochre-lored flatbill was originally described as Muscipeta flaventris. The ochre-lored flatbill's taxonomy is complicated. The three subspecies of what is now the olive-faced flatbill (T. viridiceps) were previously included within the ochre-lored.

GBIF citizen-science records
It is estimated from how often the Yellow-breasted Flycatcher is recorded against all the birds logged in Yasuní National Park (245 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.
