Identification
Slim, long-tailed greenbul with an olive-brown back and gray underparts. When seen well, shows a red eye. Found in the canopy of humid forest. Can be found singly, in pairs, or in small groups. The most common vocalization is a long, descending whistle: “teeeiow.” The contrast between the dark upperparts and gray underparts make this a distinctive species by greenbul standards.
