A gray flycatcher that has a distinctive blackish tail with white outer tail feathers. It forages more like a warbler than a typical flycatcher, flitting through foliage searching carefully for insects; seldom sallies to catch flies. Often it leans forward with its tail slightly raised and spread, a behavior that may flush insects nearby. It forages unobtrusively in broadleaf woodland, thickets, and forest edge, where it is most often detected by its trembling, mournful “wheeely-wheerr” song. The similar Gray-throated Tit-Flycatcher prefers lowland rainforest and has an all-dark tail and a plain gray face, while Ashy Flycatcher has an all-dark tail and hunts by perching and sallying like a typical flycatcher.
