Tagula Shrikethrush Colluricincla discolor

A chunky bird with a notably thick dark bill. Fairly nondescript: olive-brown on the upperparts and paler below. Found at low and middle elevations, in the understory and at middle levels of humid forest. Rich, melodious, variable song consists of whistles and rasping notes, often in an up-and-down pattern. Within its limited range, most likely to be confused with female Louisiade Whistler, but drabber overall, without yellow underparts.
