The tooth-billed pigeons are the only genus (Didunculus) of the subfamily Didunculinae, in the pigeon and dove family, (Columbidae). It has no close living relatives, but it has been shown to be genetically close to the dodo, and the genus name Didunculus means "little dodo". The jaw and tongue structure, and the superficially parrotlike bill have suggested a relationship to the parrots, but these features have arisen from its specialised diet rather than any real relationship.
