Small, uncommon flycatcher of rainforest canopy. Plain, inconspicuous, and unobtrusive; occurs in tall forest, especially on sandy soils, and may also be found in shorter-stature forest on similar soil types. Almost always seen with mixed-species flocks, and usually from below, whereby it is best distinguished from other small flycatchers by longish bill and (especially) long tail held slightly cocked. If seen from above, note long-tailed shape and bold wing bars. Feeds actively on insects taken in short sallies to leaf clusters. Easily-overlooked call is a sharp, inflected squeak, often run into an erratic series. More active and narrower-billed than Gray-crowned and Yellow-margined flycatchers, which have similar shape and posture and often occur with it in flocks.
