Small, long-tailed flycatcher of mid-elevation montane forest. Tends to perch fairly horizontally, foraging around the mid-story and canopy. Pale below, drab olive above, with yellow feather edges on the wing and tail and a gray head. Notice the white wingbars and eyebrow. Paler and drabber than other similar species like Buff-banded Tyrannulet; brighter white wingbars can also be a good distinguishing feature. Sclater’s song is a series of froggy churrs, interspersed with sharp “tlit” notes.
