Small and active “Pallas’s-type” leaf warbler with a long yellow brow stripe and pale rump. Yellowish-olive overall with two tan wingbars, one much larger than the other. White outer tail feathers typically invisible when perched, but eye-catching when the bird is hovering or landing. Extremely similar to other “Pallas’s-type” warblers, but combination of orangish wingbars, weak crown stripe, and rather uniform underparts is diagnostic. Pallas’s Leaf Warbler has a brighter crown stripe, a flashier rump patch, and yellow wingbars. Buff-barred’s head can sometimes have a gray wash similar to that of Ashy-throated Warbler, but it lacks that species’ clean white brow stripe. Buff-barred is common in hilly and montane forests, often as part of mixed-species flocks; listen out for its loud “tzeet” notes and shrill buzzy trill of a song.
