Description

The species is a medium-sized whistler, typically around in length and weighing , though some subspecies are larger. In the nominate subspecies the male has a dark slate-grey crown, face and nape, a white throat, ochraceous-yellow belly and rump, and olive back and wings with a black line between the throat and belly. The legs are dark brown. Males of other subspecies share the white throat, but are less ochraceous below, and may –depending on the exact subspecies involved– have a far broader black band between the throat and belly, and a black or olive crown, face and nape. In the nominate subspecies the female is duller than the male with a buff belly and rump, no line between the throat and belly, and an olive-brown head, back and wings. The legs are lighter brown than in the male. Females of some other subspecies have a yellow belly, and a greyish, brownish or olive throat.

Behaviour and ecology

Breeding

A small nest (6 cm in diameter) is built out of sticks and spider web and suspended from small branches above the ground. Two eggs, which are white and blotched with brown, are laid and incubated by both parents.

Food and feeding

The Melanesian whistler feeds on insects, also taking snails and seeds. It feeds in the foliage of trees and shrubs, and on the branches, presumably in a similar fashion to the closely related golden whistler.
