Large Rapa Pigeon (cf. Ducula sp.)

This species is known from several subfossil remains that were recovered from deposits on the island of Rapa, Austral Islands. 

These remains come from a larger species, like a larger Ducula sp., and shows some indications of reduced powers of flight or even flightlessness, which is now known from several extirpated Polynesian pigeon species. [1]

The sole surviving pigeon species on the island of Rapa today is the Rapa Fruit-Dove (Ptilinopus huttoni Finsch), which itself is somewhat aberrant and unusual large for a member of its genus.
