Physical charateristics
Like most flycatchers, it is difficult to identify with the voice being generally more reliable. It is olive above with a grey head, white lores and a narrow eye-ring. The wings are dark with yellow edging and two yellow wing-bars. The bill is flat, black above and pale below. The throat is pale, the breast olive and the belly pale yellow. It is sometimes seen trembling with outstretched wings.

Latin America : South Mexico to Southeast Brazil
Habitat
Its natural habitats are subtropical or tropical dry forests, subtropical or tropical moist lowland forests, subtropical or tropical moist montane forests, and heavily degraded former forest. It is more of a woodland than a forest bird but is also found on Amazon river islands and similar riverside habitat.
Reproduction
The Yellow-olive Flycatcher builds a hanging nest which can be conspicuous and consists of a retort-like nest chamber with a long entrance tube attached to the side. It is built 1-10 meter above ground. Clutch size is 2-3 eggs incubated for about 17 days by female only. The fledge after about 3 weeks and are fed by both parents.
Feeding habits
Forages alone or in pairs for insects. Prey is caught by short sallying form a perch. Will join miexed-species flocks.
Conservation
This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend appears to be stable, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size is extremely large, and hence does not approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.
