Bulky green pigeon of forested areas. Male has a bright orange breast with a pink upper quarter and a powder-blue nape. Female is green overall with a fainter blue-gray nape patch than the male. Both sexes are similar to Pink-necked Green-Pigeon, with which this species associates; note green face and throat in the male and weak but distinct nape patch in the female Orange-breasted Green-Pigeon. Often forages in numbers at fruiting trees alongside other pigeon species. Song is bizarre: a long rising note followed by a nasal, blubbering twitter.
