Medium-sized brownish bird of the subtropical zone in the Andes from western Venezuela to Bolivia. Bold buffy streaking on head, back, and underparts, though streaking is narrower and slightly more diffuse than on Flammulated Treehunter (especially on underparts). Singles or pairs inhabit the undergrowth of montane forest, especially around bamboo. Occurs from around 1,500–2,500 m, generally lower than Flammulated.
