Identification
A chunky bird with a notably thick dark bill. Quite plain: gray-brown on the upperparts and paler below, with indistinct breast streaking. Overall color varies geographically from dark gray to paler and browner, especially on the underparts. Found at low and middle elevations in humid forest, including secondary forest. Rich, melodious, variable song consists of several penetrating whistles, generally in an up-and-down pattern, often ending with a sharp upslurred note. Somewhat similar to Rusty Pitohui, but smaller, with a dark rather than pale eye. Can be very similar to Sooty Shrikethrush and Black Pitohui, but slightly paler, especially on the underparts, and shows some streaking on the breast.
