The throat is vinous, the breast is greyish-vinous, and the belly is greyish-fawn. The beak is slaty-blue, having a black tip. The eye is dark red or brownish, and the feet are red.

This pigeon is found in the Bismarck Archipelago, the Solomon Islands archipelago and small islands to the north and east of New Guinea. Its habitat is coastal primary forest, old secondary forest, mangroves and some disturbed habitats.

One or two birds and small flocks are usually found; large flocks are occasionally seen. The pigeon flies swiftly and directly. It plucks fruits from branches in the canopy, and it flies across the sea to search for food. Its calls include a rising and repeated c-wooooohooo given when the bird is upright, a loud series of descending coos while bobbing up and down, and a high-pitched crrrrrurrr. In display, it flies up at an angle of 70° and then glides. Breeding has been observed from June to September and in March. The nest is built at the end of a branch and made of twigs. One egg is laid.
