The Marianne white-eye (Zosterops semiflavus), also known as Seychelles chestnut-sided white-eye or Seychelles yellow white-eye, is an extinct species of small bird in the white-eye family.
Edward Newton described it as a full species Zosterops semiflava in 1867, though subsequently it was considered a subspecies of the Mayotte white-eye. After a 2006 study showed [1] that the Marianne white-eye is more closely related to the Karthala white-eye from Grande Comore and the white-eyes from the Mascarenes, the IOC restored it to a full species. [2] The IUCN recognized it as full species in 2016.
It reached a size of 10 cm (3.9 in), the wing length was 5.8 to 6.3 cm (2.3 to 2.5 in), the length of the tail was 3.8 cm (1.5 in) and the length of the culmen 1.1 to 1.2 cm (0.43 to 0.47 in). It was generally greenish yellow with chestnut-coloured flanks and a conspicuous white eye-ring. The forehead and a line above the eyes were yellow. The top of the head and the back were yellow olive. The wings and the tail were black and the underparts were pale yellow. It was similar in appearance to the Mayotte race of the Malagasy white-eye (Zosterops maderaspatanus mayottensis). Nothing is known of its ecology. [3]
It is known with certainty only from the small granitic islet of Marianne Island [0.962 sq mi (2.49 km2)] in the Seychelles about 6 km (3.7 mi) east of La Digue. Reports that it also occurred on Praslin, La Digue, Silhouette Island and Mahé are unconfirmed. Due to the habitat destruction through agricultural development it apparently became extinct between 1870 and 1900 (according to IUCN around 1888). An expedition in 1940 led by Irish zoologist Desmond Vesey-Fitzgerald failed to find it. There is one specimen in the Natural History Museum in London. [4]
Zosterops is a genus of passerine birds containing the typical white-eyes in the white-eye family Zosteropidae. The genus has the largest number of species in the white-eye family. They occur in the Afrotropical, Indomalayan, and Australasian realms. Typical white-eyes have a length of between 8 and 15 cm. Their most characteristic feature is a conspicuous white feather ring around the eye, though some species lack it. The species in this group vary in the structural adaptations of the tongue. The Zosterops [griseotinctus] group is an example of a "great speciator" inhabiting a vast area and showing a remarkable morphological differentiation on islands, some of which maybe as close as 2 km (1.2 mi) apart.

The Seychelles parakeet or Seychelles Island parrot is an extinct species of parrot that was endemic to the Seychelles in the Indian Ocean. It was scientifically named Palaeornis wardi by the British ornithologist Edward Newton in 1867, and the specific name honours the British civil commissioner Swinburne Ward who procured the specimens that formed the basis for the description. It was found on the islands of Mahé, Silhouette, and possibly Praslin. Ten skin specimens exist today, but no skeletons. Though the species was later moved to the genus Psittacula, genetic studies have led some researchers to suggest it should belong in a reinstated Palaeornis along with the closely related Alexandrine parakeet (P. eupatria) of Asia.
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 Réunion grey white-eye is a small passerine from the family Zosteropidae, which is native to the islands of Réunion.
The Malagasy kestrel, also known as the Madagascar kestrel, Malagasy spotted kestrel, Newton's kestrel, Madagascar spotted kestrel, katiti (Creole) or hitsikitsika (Malagasy), is a small bird of prey of the genus Falco. It is named after British ornithologist Edward Newton. It occurs in two subspecies on Madagascar and at Aldabra. The race from Aldabra is also called Aldabra kestrel. Its closest living relative is the Seychelles kestrel; they were at one time considered conspecific. Their common ancestors appear to have diverged very recently, probably less than 1 million years ago during the Early or Middle Pleistocene. The Mauritius kestrel is more distantly related.(Groombridge et al. 2002)
The Seychelles paradise flycatcher is a rare bird from the genus of paradise flycatchers (Terpsiphone) within the family Monarchidae. It is a forest-dwelling bird endemic to the Seychelles where it is native to the island of La Digue. Males have glossy black plumage with elongated tail feathers, while females are reddish-brown with pale underparts and no long tail feathers. The International Union for Conservation of Nature lists this bird as being "Vulnerable" and attempts have been made to increase its numbers by relocating some individuals to Denis Island, another island in the Seychelles archipelago.
The Seychelles white-eye is a rare warbler-like perching bird from the family of white-eyes (Zosteropidae). It is endemic to the Seychelles. At one time thought to be extinct, it was rediscovered and is now listed as Vulnerable by the IUCN.
The Comoro blue pigeon is a species of bird in the family Columbidae. It is endemic to the Comoros and the coralline Seychelles. It is rated as a species of near threatened on the International Union for Conservation of Nature Red List of Endangered Species.
The Vanuatu white-eye or yellow-fronted white-eye is a small passerine bird belonging to the genus Zosterops in the white-eye family Zosteropidae. It is endemic to Vanuatu, where it is one of the most common birds.
The nelicourvi weaver is a species of bird in the family Ploceidae. It is endemic to Madagascar. Together with its closest relative, the sakalava weaver, it is sometimes placed in a separate genus Nelicurvius. A slender, sparrow-like bird, it is 15 cm (5.9 in) long and weighing 20–28 g (0.71–0.99 oz). Breeding males have a black bill and head, brown eyes, yellow collar, grey belly, chestnut-brown lower tail coverts, olive back, and blackish flight feathers edged greenish. Non-breeding males have mottled grey and green heads. In the breeding female the front of the head is yellow and the back olive green, with a broad yellow eyebrow. It builds solitary, roofed, retort-shaped nests, hanging by a rope from a branch, vine or bamboo stem, in an open space. It primarily feeds on insects, looking on its own or in very small groups, often together with long-billed bernieria. Its natural habitat is subtropical or tropical moist lowland and mountain forests. The conservation status of Nelicourvi weaver is least concern according to the IUCN Red List.
The Mascarene paradise flycatcher is a species of bird in the monarch-flycatcher family Monarchidae. It is endemic to the Mascarene islands of Mauritius and Réunion. There are two subspecies recognized: the nominate subspecies from Réunion, also known as the Réunion paradise flycatcher; and T. b. desolata from Mauritius. The Mascarene paradise flycatcher was originally described in the genus Muscicapa and the subspecies T. b. desolata was originally described as a separate species.
The Malagasy white-eye is a species of bird in the white-eye family, Zosteropidae. Found in Madagascar and Seychelles, its natural habitats are subtropical or tropical dry forests, subtropical or tropical moist lowland forests, subtropical or tropical mangrove forests, and subtropical or tropical moist montane forests.
The Mayotte white-eye or chestnut-sided white-eye is a species of bird in the family Zosteropidae. It is now found only on Mayotte in the Comoro Islands. Its natural habitats are subtropical or tropical dry forests, subtropical or tropical moist lowland forests, and subtropical or tropical mangrove forests.
The grey-throated white-eye is a species of bird. Its family, the Zosteropidae, is probably not valid and belongs in the Timaliidae instead. It is also known as Zosterops ugiensis because Z. rendovae has often been used for the Solomons white-eye.
The green-backed white-eye is a species of bird in the family Zosteropidae. It is also known as the New Caledonian white-eye. It is endemic to New Caledonia.
Kirk's white-eye is a species of bird in the family Zosteropidae. It is endemic to the Comoros Islands. It was previously considered a subspecies of the Malagasy white-eye. Its common and binomial name are in honour of explorer John Kirk.
The Meratus white-eye is a species of bird in the white-eye family, Zosteropidae. The species was described in 2021 by the Indonesian ornithologist Mohammed Irham and his colleagues based on genetic, morphological, and vocal differences from other Zosterops white-eyes. It is endemic to the Meratus Mountains of Indonesian Borneo, where it has been recorded from Mount Besar and Mount Karokangen. It inhabits the mid and lower storeys of closed-canopy montane forests at elevations between 1,300 and 1,650 m. It is a typical Zosterops white-eye, with deep olive-green upperparts, yellower underparts, a yellow stripe across the lores, and a distinctive bicoloured bill. Adults have a length of around 11–12 cm (4.3–4.7 in) and a mass of 8.5–9.5 g (0.30–0.34 oz). Both sexes look alike.
