The Mauritius olive white-eye (Zosterops chloronothos, [3] [4] [5] often mistakenly spelled Zosterops chloronothus [6] [7] ) is a very rare and localized passerine from the family of white-eyes (Zosteropidae). It is one of two white-eye species endemic to the island of Mauritius, the other being the Mauritius grey white-eye.
This species was first described in 1817 by French ornithologist Louis Pierre Vieillot as Zosterops chloronothos. It can reach a size of about 10 cm. The upperparts are a dull olive-green, the underparts a paler color. The belly and vent have a yellow hue and the eyes are surrounded by a conspicuous white ring. The males and females are similarly coloured. The habitat of the Mauritius olive white-eye is the evergreen bushes and forests in the area of the Black River Gorges National Park, the Macchabée-Bel Ombre Biosphere Reserve and, following re-introduction, on Île aux Aigrettes. Its diet consists of nectar and insects.
During the breeding period, between September and March, two pale eggs are laid in a cup-shaped nest, which is well-hidden in the foliage. Males and females share brooding tasks. Normally only one juvenile is reared, which becomes fully fledged in about 14 days.
The Mauritius olive white-eye is one of the rarest birds on Mauritius. Difficult to observe, the birds inhabit an area of only 25 km². The main threats are introduced rats and crab-eating macaques, which destroy the nests. In only 27 years the population declined dramatically from 350 pairs in 1975 to only 120 pairs in 2002. Another reason for its rarity is that the Mauritius olive white-eye has evolved around the nectar of several endemic flowers from Mauritius. The introduction of other plant species has led to a decline in the required flowers and hence to severely decreasing numbers of the birds. Currently there is a monitoring by the Mauritian Wildlife Foundation (MWF) for every found nest.
There are a few organizations that have been working on the protection of the Mauritius olive white-eye but the MWF has had the most impact. From 2005 to 2009, they've collected nests all around Mauritius for two major reasons. First, so the eggs wouldn't be eaten, and secondly, so that when they grow, they can be released on predator-free islands. To achieve that outcome, when the egg hatches, the chick immediately needs to follow a restricted diet that consists of eating a small portion of nutrients every forty minutes. After that, the chicks are put in small cages where they learn how to drink for themselves, to adapt to the food they will be eating soon enough and then teach them how to fly. When the birds have finally adapted to that, they are freed on a predator-free island, the Ile aux Aigrettes, where they have started to reproduce.
The Virginia rail is a small waterbird, of the family Rallidae. These birds remain fairly common despite continuing loss of habitat, but are secretive by nature and more often heard than seen. They are also considered a game species in some provinces and states, though rarely hunted. The Ecuadorian rail is often considered a subspecies, but some taxonomic authorities consider it distinct.
The Indian white-eye, formerly the Oriental white-eye, is a small passerine bird in the white-eye family. It is a resident breeder in open woodland on the Indian subcontinent. They forage in small groups, feeding on nectar and small insects. They are easily identified by the distinctive white eye-ring and overall yellowish upperparts. The range previously extended eastwards to Southeast Asia, Indonesia and Malaysia. Their name was recently changed due to previous members of Zosterops palpebrosus in Southeast Asia being renamed to a new species, making the Indian White-eye a more geographically accurate term for this species.
The Sri Lanka white-eye is a small passerine bird in the white-eye family, which is endemic to Sri Lanka. It is a resident breeder in forests, gardens and plantations, mainly in the highlands.
The ringed teal is a small duck of South American forests. It is the only species of the genus Callonetta. Usually placed with the dabbling ducks (Anatinae), this species may actually be closer to shelducks and belong in the subfamily Tadorninae; its closest relative is possibly the maned duck.
The Mauritius fody is a rare species of bird in the weaver family. It is endemic to the island of Mauritius. It is classified by BirdLife International as being endangered. It is also on the United States' Endangered Species List with an endangered status.
The pink pigeon is a species of pigeon in the family Columbidae endemic to Mauritius. The pink pigeon nearly became extinct in the 1970s and the 1990s and is still very rare. It is the only Mascarene pigeon that has not become extinct. It was on the brink of extinction in 1991 when only 10 individuals remained, but its numbers have increased due to the efforts of the Durrell Wildlife Conservation Trust since 1977. While the population remains at below 500 birds as of 2011, the IUCN downlisted the species from Critically endangered to Endangered on the IUCN Red List in 2000, and then downlisted it again to Vulnerable in 2018.
The Mauritian Wildlife Foundation (MWF) is an independent, non-governmental, non-profit conservation agency working in Mauritius to save threatened endemic local flora and fauna.
The warbling white-eye, also known as the Japanese white-eye and mountain white-eye, is a small passerine bird in the white-eye family. The specific epithet is occasionally written japonica, but this is incorrect due to the gender of the genus. Its native range includes much of East Asia, including the Russian Far East, Japan, Indonesia, Korea, and the Philippines. It has been intentionally introduced to other parts of the world as a pet and as pest control, with mixed results. As one of the native species of the Japanese islands, it has been depicted in Japanese art on numerous occasions, and historically was kept as a cage bird.
Trochetia is a genus of flowering plants from the family Malvaceae. They are endemic to the Mascarene Islands.
The red-necked avocet also known as the Australian avocet, cobbler, cobbler's awl, and painted lady, is a wader of the family Recurvirostridae that is endemic to Australia and is fairly common and widespread throughout, except for the north and north east coastal areas of the country. Closely related to the stilts, it shares their fragile slender elegance, however the deep red head and neck distinguish them. It appeared on a 13 cent postage stamp in 1966.
The Australasian grebe is a small waterbird common on fresh water lakes and rivers in greater Australia, New Zealand and on nearby Pacific islands. At 25–27 cm (9.8–10.6 in) in length, it is one of the smallest members of the grebe family, along with the least grebe and little grebe.
The white-chested white-eye also known as white-breasted white-eye or Norfolk white-eye is a passerine from the family Zosteropidae. It is endemic to Norfolk Island between New Caledonia and New Zealand and it is regarded as either extremely rare or possibly extinct. Since 2000 the Australian government has considered the species extinct.
The Réunion grey white-eye is a small passerine from the family Zosteropidae, which is native to the islands of Réunion.
The Bonin white-eye or meguro (メグロ) is a small songbird endemic to the Bonin Islands of Japan. It is the only species in the genus Apalopteron. Its taxonomic affinities were a long-standing mystery and it has been placed with the bulbuls, babblers and more recently with the honeyeaters, during which it was known as the Bonin honeyeater. Since 1995 it is known to be a white-eye in the family Zosteropidae, that is closely related to the golden white-eye of the Marianas Islands.
The golden white-eye is a species of bird in the white-eye family, Zosteropidae. It is the only species within the genus Cleptornis. The golden white-eye was once considered to be a honeyeater in the family Meliphagidae and although it is now known to be a white-eye, its position within that family is still uncertain. The species is restricted to the islands of Saipan and Aguijan in the Northern Mariana Islands, where it is sympatric and competes with the related bridled white-eye. The golden white-eye has golden plumage and a pale eye-ring. It feeds on insects, fruit, and nectar and forages in pairs or small family groups. The bird is monogamous and lays two eggs in a small cup nest.
The crescent honeyeater is a passerine bird of the honeyeater family Meliphagidae native to southeastern Australia. A member of the genus Phylidonyris, it is most closely related to the common New Holland honeyeater and the white-cheeked honeyeater. Two subspecies are recognized, with P. p. halmaturinus restricted in range to Kangaroo Island and the Mount Lofty Ranges in South Australia.
The Cuban oriole is a species of songbird in the family Icteridae. It is endemic to Cuba.
The western silvereye is a small greenish bird in the Zosteropidae or White-eye family. It is a subspecies of the silvereye that occurs in Western Australia and South Australia. It is sometimes called the white-eye or greenie. Aboriginal names for the bird include jule-we-de-lung or julwidilang from the Perth area and poang from the Pallinup River.
Carl Gwynfe Jones, MBE is a Welsh conservation biologist, who has been employed by Durrell Wildlife Conservation Trust since 1985, and a founding member (1984) and current scientific director of Mauritian Wildlife Foundation (MWF). Additionally he is Chief Scientist at Durrell Wildlife Conservation Trust, and an honorary professor in ecology and conservation biology at the University of East Anglia. Often outspoken on the importance of knowing your species and using intuition, empathy and practical knowledge over dogmatic education, Jones is best known for his work in recovering the Mauritius kestrel from just four individuals in 1974, to an estimated 400. Working in the Mascarene Islands since 1979, Jones has led five successful bird restoration projects where the starting population has numbered less than 12 individuals; as a consequence Mauritius has averted more bird extinctions than any other country. Jones has pioneered the use of ecological or taxon replacements to fill the ecological roles of extinct animals and successfully restored levels of endemic vegetation to previously denuded islets. Jones' work has been highlighted in Douglas Adams and Mark Carwardine's 1990 radio documentary Last Chance to See, along with its accompanying book, as well as David Quammen's 1996 book The Song of the Dodo: Island Biogeography in an Age of Extinctions.
Ile aux Aigrettes is an islet off the south-east coast of Mauritius. It functions as a nature reserve and a scientific research station. It is also a popular visitors attraction - both for tourists and for Mauritians.
