Similar Species
Yellow-olive Flatbill differs in lacking white speculum at base of primaries and in having usually narrower yellow edges to wings that however does give hint of wing bar. Eyes usually paler than those in this species.
The formerly conspecific Yellow-margined Flatbill does not overlap in range but differs in narrower yellow edges to wing feathers. Probably best separated by voice.
Distribution
Central and South America: Southern Nicaragua, Costa Rica, and Panama to western Colombia and north-western Ecuador (everywhere west of the Andes).
Taxonomy
This is a monotypic species[1].
This species was formerly included within Yellow-margined Flatbill.
Habitat
Wet forests including taller second growth and plantations. In western Panama also found in swamp forests.
Behaviour
Concentrates on mid-story to canopy, but seems to go lower at edge of forests. Assumed to use similar food capture process as Yellow-margined Flatbill and to live from mainly smaller invertebrates with only a little fruit.
Vocalisation
Song has a 1-4 structure, first one note, a short pause, then four more notes more closely together. First note usually of lower pitch, the rest identical.
