Fairly small brown bird, shows a thin buffy line behind the eye and thin buffy streaking all over head, back, and underparts. Throat is cleaner buffy. In many parts of range, this is the only foliage-gleaner with such obvious streaking. In some regions, beware treehunters, which are larger and longer-billed. Found in montane forests, where it usually follows mixed flocks through the forest understory. Stays in the lower levels, probing around tangles and leaf clusters. Listen for series of forced nasal notes.
