Ochre-lored Flatbill

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. == 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 (Wied-Neuwied, 1831), T. f. aurulentus (Todd, 1913), and T. f. dissors (Zimmer, JT, 1939). 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. 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 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 have a yellowish olive head with a brighter ochre-tinged stripe above the lores and…
