The adult identification account describes a bluish-glossed black head, neck, throat, and breast, with a bluish-grey back and wings and a white belly and undertail-coverts. Females are described with a sooty-grey head or grey throat and a lighter grey breast.
It occurs mainly in primary hill forest, as well as selectively logged forest, tall secondary forest, coastal casuarina, and sometimes mangroves. It forages in the upper tree levels; its diet is not known.
