Tooth-billed Pigeon (Didunculus strigirostris)
Didunculus or tooth-billed pigeons, is a genus of pigeons in the Columbidae family. 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 parrot-like bill have suggested a relationship to the parrots, but these features have arisen from its specialised diet rather than any real relationship.
The Tongan tooth-billed pigeon (Didunculus placopedetes) is only known from subfossil remains in several archaeological sites in Tonga dating 2700–2850 BP and now extinct. The tooth-billed pigeon (Didunculus strigirostris) from Samoa is critically endangered.
It contains the following species:
