A large, richly colored greenbul, yellow-olive on the back and yellow below with a red eye. Found locally in humid forest at middle elevations, usually in groups, at middle levels of the forest and in the sub-canopy. More colorful than other greenbuls that overlap in range. Similar to Prigogine’s Greenbul, but distinguished by the lack of gray on the face and lack of white on the chin. Named for its exuberant song, several chattering calls that ascend and accelerate into a bubbly, explosive sequence, usually given by multiple birds together.
