Tiny Greenbul Phyllastrephus debilis

A very small, warbler-like greenbul with an olive-green back, pale underparts, a gray cap and nape, and a pale eye. Found in lowland forest and lush woodland. Often joins mixed-species flocks. Very similar to Usambara Greenbul, but found at lower elevations and paler overall, without an olive-green wash to the crown and the back of the head. Similar in overall coloration to Yellow-streaked Greenbul, but much smaller, with a pale eye. The call is a rough chatter that is often mixed with the song: an accelerating, syncopated series of low nasal notes.
