The Eastern Olivaceous Flatbill is a quiet, canopy-to-understory tyrant flycatcher with a characteristically broad, flat bill used to snatch insects from foliage and in short sallies. It often keeps to shaded forest interiors, making it easier to detect by voice than by sight. Pairs or family groups may accompany mixed-species flocks. Its subtle olive tones and buffy wingbars make it a classic example of low-contrast tropical forest plumage.
Temperament
shy and unobtrusive
Flight Pattern
short rapid wingbeats with brief sallies from low to mid-level perches
Social Behavior
Typically found singly, in pairs, or small family groups, and frequently associates with mixed-species flocks while foraging. Breeding pairs defend small territories within suitable forest. The nest is a suspended pouch-like structure woven from plant fibers and other fine materials, often placed low to mid-level in dense vegetation.
Migratory Pattern
Resident
Song Description
Gives soft, whistled phrases and thin tseet notes, often repeated at intervals from a concealed perch. The song can include a simple descending whistle or a series of mellow, slightly burry notes. Calls are subtle and easily overlooked amid forest background sounds.
