An unusual warbler with a long, straight bill and a pale eye. Mostly dull olive-green with a yellowish throat. Found locally along the Angolan escarpment in dry evergreen forest at low middle elevations, mainly in dense tangles at middle levels of the forest. Could be confused with camaropteras, but larger, without a bright green wing. Also similar to some greenbuls, but smaller and shorter-tailed. Usually detected by the distinctive song: a repeated, low-pitched, two-note “peet-treeya” phrase.
