The adult is a uniform drab-olive greenbul, slightly paler on the belly, with striking pale eyes that are characteristic. Juveniles have dark eyes and a small yellow gape. Pairs skulk and can be quite secretive in the midstory and canopy of forest, forest edge, and thickets up to 2000 meters of elevation, foraging on fruits and insects. It is often first detected by its loud, shrill “Willie! …..come out and play with me” song, ending with a nasal “sca-a-ared.” Northern birds sing a different song with a similar quality.
