Sassi's Greenbul Phyllastrephus lorenzi

A small, relatively distinctive, but very poorly known greenbul of the eastern Democratic Republic of Congo. Looks like a typical greenbul overall, but also has an unusual dark blackish cap that, with a good view, easily separates it from other greenbuls. Found in rainforest at middle elevations, where it feeds in the understory and at middle levels of the forest, often in small groups. The voice is unknown.
