The Rodrigues Parrot or Leguat's Parrot (Necropsittacus rodericanus) is an extinct species of parrot which once lived on the Mascarene island of Rodrigues in the Indian Ocean east of Madagascar. It is unclear what other species it is most closely related to, but it has been classified as a member of the tribe Psittaculini, along with other Mascarene parrots. It had similarities with the broad-billed parrot, and may have been closely related.

The Rodrigues parrot was green, and had a proportionally large head and beak along with a long tail. Its exact size is unknown, but it may have been around 50 cm (20 in) long. It may have looked similar to the great-billed parrot. It frequented and nested on islets off southern Rodrigues to avoid introduced rats, and fed on the seeds of the Fernelia buxifolia shrub. The species is known from subfossil bones and from mentions in three contemporary accounts. It was last mentioned in 1761, and probably went extinct soon after, probably due to a combination of predation by rats, deforestation, and hunting by humans.


Parrots matching the Rodrigues parrot were first mentioned by François Leguat in 1708 and Julien Tafforet in 1726, who were both marooned on Rodrigues. The parrot was scientifically described as Psittacus rodericanus by the French ornithologist Alphonse Milne-Edwards in 1867. He moved it to its own genus in 1874. The binomial, Necropsittacus rodericanus, translates to "dead parrot of Rodrigues", in reference to its extinction. The holotype specimen is a subfossil partial beak, but its current whereabouts are unknown. It may be specimen UMZC 575, a rostrum that was sent from Milne-Edwards' to Alfred Newton after 1880, which matches the drawing and description in Milne-Edwards' paper, but this cannot be confirmed. In addition, subfossil remains of at least four individuals have been found in the Plaine Corail.

After examining a skull of the Rodrigues parrot, Edward Newton and Hans Gadow found it to be closely related to the broad-billed parrot due to their large jaws and other osteological features, but were unable to determine whether they both belonged in the same genus, since a crest was only known from the latter. Graham S. Cowles instead found their skulls too dissimilar for them to be close relatives. The skeleton of the Rodrigues parrot has similarities with the Tanygnathus and Psittacula parrot genera.

In his 1907 book Extinct Birds, Walther Rothschild placed two hypothetical parrot species in the Necropsittacus genus; the Réunion parrot (Necropsittacus? borbonicus) and the Mauritian parrot (Necropsittacus? francicus). The former was based on a single account by Sieur Dubois, and it is uncertain what the source for the latter is, so both are considered dubious today.


Many endemic Mascarene birds, including the Dodo, are derived from South Asian ancestors, and the English palaeontologist Julian Hume has proposed that this may be the case for all the parrots there as well. Sea levels were lower during the Pleistocene, so it was possible for species to colonise some of the then less isolated islands. Although most extinct parrot species of the Mascarenes are poorly known, subfossil remains show that they shared features such as enlarged heads and jaws, reduced pectoral bones, and robust leg bones.

Hume has suggested that they have a common origin in the radiation of the Psittaculini tribe, basing his theory on morphological features and the fact that Psittacula parrots have managed to colonise many isolated islands in the Indian Ocean. The Psittaculini may have invaded the area several times, as many of the species were so specialised that they may have evolved significantly on hotspot islands before the Mascarenes emerged from the sea. A 2011 genetic study instead found that the Mascarene parrot (Mascarinus mascarinus) of nearby Réunion was most closely related to the lesser vasa parrot (Coracopsis nigra) from Madagascar and nearby islands, and therefore unrelated to the Psittacula parrots, undermining the theory of their common origin.



The possibly similar great-billed parrot

The Rodrigues parrot was described as large and with a big head and a long tail. Its plumage was described as being of uniform green colouration. Its skull was flat and depressed compared to those of most other parrots, but similar to the genus Ara. The skull was 50 mm (2.0 in) long without the beak, 38 mm (1.5 in) wide, and 24 mm (0.94 in) deep. Its exact body length is unknown, but it may have been around 50 cm (20 in). Its size has been likened to that of a large cockatoo. Its tibia was 32% smaller than that of a female broad-billed parrot, yet the pectoral bones were of similar size, and proportionally its head was the largest of any Mascarene species of parrot.

The pectoral and pelvic bones were similar in size to those of the New Zealand kaka (Nestor meridionalis), and it may have looked similar to the great-billed parrot (Tanygnathus megalorynchos) in life, but with a larger head and tail. It differed from other Mascarene parrots in several skeletal features, including having nostrils that faced upwards instead of forwards. No features of the skull suggest it had a crest like the broad-billed parrot, and there is not enough fossil evidence to determine whether it had pronounced sexual dimorphism. There are intermediate specimens between the longest and shortest examples of the known skeletal elements, which indicates there were no distinct size groups.
