The Mascarene parrot or mascarin (Mascarinus mascarinus) is an extinct species of parrot that was endemic to the Mascarene island of Réunion in the western Indian Ocean. The taxonomic relationships of this species have been subject to debate; it has historically been grouped with either the Psittaculini parrots or the vasa parrots, with the latest genetic study favouring the former group.
The Mascarene parrot was in length with a large red bill and long, rounded tail feathers. Its legs were red, and it had naked red skin around the eyes and nostrils. It had a black facial mask and partially white tail feathers, but the colouration of the body, wings and head in the living bird is unclear. Descriptions from life indicate the body and head were ash grey, and the white part of the tail had two dark central feathers. In contrast, stuffed specimens and old descriptions based on them indicate that the body was brown and the head bluish. This may be due to the specimens having changed colour as a result of ageing and exposure to light. Very little is known about the bird in life.
The Mascarene parrot was first mentioned in 1674, and live specimens were later brought to Europe, where they lived in captivity. The species was scientifically described in 1771. Only two stuffed specimens exist today, in Paris and Vienna. The date and cause of extinction for the Mascarene parrot is unclear. The latest account, from 1834, is considered dubious, so it is probable that the species became extinct prior to 1800, and may have become extinct even earlier.
The Mascarene parrot was first mentioned by the French traveller Sieur Dubois in his 1674 travelogue and only described a few times from life afterwards. At least three live specimens were brought to France in the late 18th century and kept in captivity, two of which were described while alive. Today, two stuffed specimens exist; the holotype, specimen MNHN 211, which is in the Muséum National d'Histoire Naturelle in Paris, while the other, specimen NMW 50.
