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.

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 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.
