Ochre-lored flatbill
The ochre-lored flatbill 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.
Taxonomy and systematics
The ochre-lored flatbill was originally described as Muscipeta flaventris.The ochre-lored flatbill's taxonomy is complicated. As of early 2025 it was assigned three subspecies, the nominate T. f. flaventris, T. f. aurulentus, and T. f. dissors. The three subspecies of what is now the olive-faced flatbill were previously included within the ochre-lored. Taxonomic systems began separating them in 2020 and the process continued into 2024. Two other subspecies, T. f. collingwoodi and T. f. gloriosus have been proposed to be separated from T. f. aurulentus. They might be valid, and some subspecies may warrant treatment as full species.
Description
The ochre-lored flatbill is about long and weighs. The sexes have the same plumage. Adults of the nominate subspecies have a yellowish olive head with a brighter ochre-tinged stripe above the lores and a brighter ochre-tinged eye-ring. Their back, rump, and uppertail coverts are yellowish olive. Their wings are dusky with yellowish edges on the coverts and remiges that appear as two wing bars. Their tail is dusky. Their underparts are bright yellow with an olive to ochre wash on the throat and breast and lightly on the belly. Subspecies T. f. aurulentus is darker overall than the nominate with richer yellow underparts. T. f. dissors is slightly smaller than the nominate but otherwise the same. All subspecies have a brown or red-brown iris, a wide flat dark gray or black bill with sometimes a pinkish base to the mandible, and blue-gray or black legs and feet.Distribution and habitat
The ochre-lored flatbill ranges from eastern Panama to Bolivia and southern Brazil. Subspecies T. f. aurulentus is the northernmost. It is found from eastern Panama east through northern and eastern Colombia, in northern and central Venezuela from Zulia south into Bolívar, in the Guianas, in northern Brazil north of the Amazon from the Branco River to the Atlantic in Amapá and northern Pará, and on Trinidad, Tobago. Subspecies T. f. dissors is found from northwestern Bolívar and Amazonas states in southern Venezuela south and east in Brazil from the Tapajós River to the Tocantins River. The nominate subspecies is found in eastern Brazil south of the Amazon from Maranhão south to Mato Grosso and coastally to Rio de Janeiro, and into eastern Bolivia's Santa Cruz Department.The ochre-lored flatbill inhabits a wide variety of landscapes. These include dry to humid forest and woodlands, gallery forest, restinga, and caatinga. In the Amazon Basin it mostly is found along waterways, often at the edge of várzea. It less often occurs in terra firme and savanna woodland, though more often in savanna in Venezuela than elsewhere. On Trinidad and in the Guianas it inhabits mangroves. In elevation it reaches in Colombia, in Venezuela, and in Brazil.
