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. Taxonomic systems began separating them in 2020 and the process continued into 2024. They might be valid, and some subspecies may warrant treatment as full species.
The ochre-lored flatbill is about 12 to 13 cm (4.7 to 5.1 in) long and weighs 9 to 17.5 g (0.32 to 0.62 oz). The sexes have the same plumage. Adults of the nominate subspecies... Wikipedia →

Rare
Under 5% of wildlife watchers report a Yellow-breasted Flycatcher sighting in Tambopata National Reserve on a given day, based on 118 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 281st most-seen of the 550 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
July
In that month about 10% of wildlife watchers report a Yellow-breasted Flycatcher in Tambopata National Reserve on a given day, against under 5% in August to June, the lowest months. That is one of Tambopata National Reserve's driest months, with about 45 mm of rain against 420 mm in February.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Yellow-breasted Flycatcher sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
11th of 15
Of the 15 parks where we can rate Yellow-breasted Flycatcher sightings, Tambopata National Reserve ranks 11th at under 5%. The best odds are in Main Ridge Forest Reserve (Trinidad and Tobago, about 40%), Chapada Diamantina National Park (Brazil, about 30%) and Tayrona National Natural Park (Colombia, about 20%).
GBIF citizen-science records
It is estimated from how often the Yellow-breasted Flycatcher is recorded against all the birds logged in Tambopata National Reserve (118 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.
