The maroon shining parrot (Prosopeia tabuensis) is a species of parrot in the family Psittaculidae. It is native to Fiji and Tonga, where its habitats include forests, plantations, mangroves and gardens. Adults have dark-maroon underparts, green upperparts, and a blue collar of variable prominence. The species feeds mainly on fruit and seeds, nests in tree cavities, and usually lays two or three eggs. Known as the koki in Tonga, it can mimic human speech but is rarely kept in captivity. This maroon shining parrot was photographed on Taveuni, the third-largest island in Fiji.
