The Mauritius ground thrush, Geokichla longitarsus, was a species of long-legged [2] thrush within the Turdidae family. [3] Endemic to Mauritius, [1] the Mauritius ground thrush has since gone extinct, probably during the 14th century.
The Mauritius ground thrush is based on the holotype (MNHN MAD7127, MNHN MAD 7172 and MNHN MAD 8850), a subfossil specimen discovered by Etienne Thirioux before 2013 [3] in the Vallée des Prêtres near Port Louis, Mauritius that consists solely of limb bones including a tarsometatarsus, humeri and tibiotarsi. [1] It was similar in anatomy to the orange-headed thrush from Asia. [1]
The Mauritius ground thrush was not mentioned by the early Dutch settlers of Mauritius who began to document the island's fauna and flora, starting in the 16th century, [1] so it was likely extinct before the Dutch began to settle the island on 20 September 1598.
The leading theory towards the extinction of the Mauritius ground thrush is that it may have gone extinct during the 14th century when Arab traders introduced black rats onto the island of Mauritius. [1]
The dodo is an extinct flightless bird that was endemic to the island of Mauritius, which is east of Madagascar in the Indian Ocean. The dodo's closest relative was the also-extinct and flightless Rodrigues solitaire. The two formed the subfamily Raphinae, a clade of extinct flightless birds that were a part of the family which includes pigeons and doves. The closest living relative of the dodo is the Nicobar pigeon. A white dodo was once thought to have existed on the nearby island of Réunion, but it is now believed that this assumption was merely confusion based on the also-extinct Réunion ibis and paintings of white dodos.
Newton's parakeet, also known as the Rodrigues parakeet or Rodrigues ring-necked parakeet, is an extinct species of parrot that was endemic to the Mascarene island of Rodrigues in the western Indian Ocean. Several of its features diverged from related species, indicating long-term isolation on Rodrigues and subsequent adaptation. The rose-ringed parakeet of the same genus is a close relative and probable ancestor. Newton's parakeet may itself have been ancestral to the endemic parakeets of nearby Mauritius and Réunion.
The Réunion ibis or Réunion sacred ibis is an extinct species of ibis that was endemic to the volcanic island of Réunion in the Indian Ocean. The first subfossil remains were found in 1974, and the ibis was first scientifically described in 1987. Its closest relatives are the Malagasy sacred ibis, the African sacred ibis, and the straw-necked ibis. Travellers' accounts from the 17th and 18th centuries described a white bird on Réunion that flew with difficulty and preferred solitude, which was subsequently referred to as the "Réunion solitaire".
The broad-billed parrot or raven parrot is a large extinct parrot in the family Psittaculidae. It was endemic to the Mascarene island of Mauritius. The species was first referred to as the "Indian raven" in Dutch ships' journals from 1598 onwards. Only a few brief contemporary descriptions and three depictions are known. It was first scientifically described from a subfossil mandible in 1866, but this was not linked to the old accounts until the rediscovery of a detailed 1601 sketch that matched both the subfossils and the accounts. It is unclear what other species it was 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 Rodrigues parrot, and may have been closely related.
The hoopoe starling, also known as the Réunion starling or Bourbon crested starling, is a species of starling that lived on the Mascarene island of Réunion and became extinct in the 1850s. Its closest relatives were the also-extinct Rodrigues starling and Mauritius starling from nearby islands, and the three apparently originated in south-east Asia. The bird was first mentioned during the 17th century and was long thought to be related to the hoopoe, from which its name is derived. Some affinities have been proposed, but it was confirmed as a starling in a DNA study.
The Rodrigues night heron is an extinct species of heron that was endemic to the Mascarene island of Rodrigues in the Indian Ocean. The species was first mentioned as "bitterns" in two accounts from 1691–1693 and 1725–1726, and these were correlated with subfossil remains found and described in the latter part of the 19th century. The bones showed that the bird was a heron, first named Ardea megacephala in 1873, but moved to the night heron genus Nycticorax in 1879 after more remains were described. The specific name megacephala is Greek for "great-headed". Two related extinct species from the other Mascarene islands have also been identified from accounts and remains: the Mauritius night heron and the Réunion night heron.
The Rodrigues rail, also known as Leguat's gelinote or Leguat's rail, is an extinct species of the rail family that was endemic to the Mascarene island of Rodrigues. The bird was first documented from life by two accounts from 1691–93 and 1725–26. Subfossil remains were later discovered and correlated with the old accounts in 1874, and the species was named E. leguati in Leguat's honour. It is generally kept in its own genus, Erythromachus, but has sometimes been assigned to the genus Aphanapteryx along with its close relative the red rail of Mauritius; their relationship with other rails is unclear.
The red rail is an extinct species of rail that was endemic to the Mascarene island of Mauritius, east of Madagascar in the Indian Ocean. It had a close relative on Rodrigues island, the likewise extinct Rodrigues rail, with which it is sometimes considered congeneric, but their relationship with other rails is unclear. Rails often evolve flightlessness when adapting to isolated islands, free of mammalian predators, and that was also the case for this species. The red rail was a little larger than a chicken and had reddish, hairlike plumage, with dark legs and a long, curved beak. The wings were small, and its legs were slender for a bird of its size. It was similar to the Rodrigues rail, but was larger, and had proportionally shorter wings. It has been compared to a kiwi or a limpkin in appearance and behaviour.
The Mauritius sheldgoose, also known as the Mauritius shelduck, is an extinct species of sheldgoose that was endemic to the island of Mauritius. While geese were mentioned by visitors to Mauritius in the 17th century, few details were provided by these accounts. In 1893, a carpometacarpus wing-bone and a pelvis from the Mare aux Songes swamp were used to name a new species of comb duck, Sarcidiornis mauritianus. These bones were connected to the contemporary accounts of geese and later determined to belong to a species related to the Egyptian goose and placed in the sheldgoose genus Alopochen. The Mauritius and Réunion sheldgoose may have descended from Egyptian geese that colonised the Mascarene islands.
The Mascarene parrot or mascarin 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 Rodrigues parrot or Leguat's parrot is an extinct species of parrot that was endemic to the Mascarene island of Rodrigues. The species is known from subfossil bones and from mentions in contemporary accounts. It is unclear to which other species it is most closely related, but it is classified as a member of the tribe Psittaculini, along with other Mascarene parrots. The Rodrigues parrot bore similarities to the broad-billed parrot of Mauritius, and may have been related. Two additional species have been assigned to its genus, based on descriptions of parrots from the other Mascarene islands, but their identities and validity have been debated.
The extinct Mauritius scops owl, also known as Mauritius owl, Mauritius lizard owl, Commerson's owl, Sauzier's owl, or Newton's owl, was endemic to the Mascarene island of Mauritius. It is known from a collection of subfossil bones from the Mare aux Songes swamp, a detailed sketch made by de Jossigny in 1770, a no less detailed description by Desjardins of a bird shot in 1836, and a number of brief reports about owls, the first being those of Van Westzanen in 1602 and Matelief in 1606.
The Mauritius blue pigeon is an extinct species of blue pigeon formerly endemic to the Mascarene island of Mauritius in the Indian Ocean east of Madagascar. It has two extinct relatives from the Mascarenes and three extant ones from other islands. It is the type species of the genus of blue pigeons, Alectroenas. It had white hackles around the head, neck and breast and blue plumage on the body, and it was red on the tail and the bare parts of the head. These colours were thought similar to those of the Dutch flag, a resemblance reflected in its French common name, Pigeon Hollandais. The juveniles may have been partially green. It was 30 cm (12 in) long and larger and more robust than any other blue pigeon species. It fed on fruits, nuts, and molluscs, and was once widespread in the forests of Mauritius.
The Rodrigues starling is an extinct species of starling that was endemic to the Mascarene island of Rodrigues. Its closest relatives were the Mauritius starling and the hoopoe starling from nearby islands; all three are extinct and appear to be of Southeast Asian origin. The bird was only reported by French sailor Julien Tafforet, who was marooned on the island from 1725 to 1726. Tafforet observed it on the offshore islet of Île Gombrani. Subfossil remains found on the mainland were described in 1879, and were suggested to belong to the bird mentioned by Tafforet. There was much confusion about the bird and its taxonomic relations throughout the 20th century.
France Staub was a Mauritian ornithologist, herpetologist, botanist, and conservationist.
The Mascarene grey parakeet, Mauritius grey parrot, or Thirioux's grey parrot, is an extinct species of parrot which was endemic to the Mascarene Islands of Mauritius and Réunion in the western Indian Ocean. It has been classified as a member of the tribe Psittaculini, along with other parrots from the Islands.

The Mare aux Songes swamp is a lagerstätte located close to the sea in south eastern Mauritius. Many subfossils of recently extinct animals have accumulated in the swamp, which was once a lake, and some of the first subfossil remains of dodos were found there.
The Geokichla thrushes are medium-sized mostly insectivorous or omnivorous birds in the thrush family, Turdidae. They were traditionally listed in the Zoothera, but molecular phylogenetic studies published in 2008 led to their placement in a separate genus.
