A medium-sized bird of montane forest midstory. Medium gray upperparts, black face and bib with indistinct, white, horizontal crescent moon below the cheek. Belly is also gray in central areas, and white on Bird’s Head and southeastern New Guinea. Juvenile is a distinctive rufous color and immatures, blotchy. Sits still in the midstory, slowly wagging its tail. Co-occurs with the similar-colored Blue-gray Robin, but is larger with a black throat. Black-bellied Cicadabird is also a similar color-scheme but much larger. Voice, a high-pitch whistle. Either a single note or identical notes given in a slurred series.
