Nesozosterops strenua

The robust white-eye (Zosterops strenuus), also known as the Lord Howe white-eye or robust silvereye and locally as the "big grinnell", was a species of bird in the family Zosteropidae. It was endemic to the lowland forests of Lord Howe Island, east of Australia.

Description

It was a mainly green bird, around 7.6 cm long, with a white belly and yellow throat, which separated it from other species of white-eye.

The robust white-eye built loosely constructed, cup-shaped nests out of palm fibre and dried grasses, which were sometimes found in shrubs overgrown with vines. This made the species vulnerable to predation by black rats (Rattus rattus), which were accidentally introduced in 1918 following the grounding of the steamship S.S. Makambo on the island. Although once common, the bird was extinct by 1923.

Despite its small size, the bird was known to islanders as "big grinnell", to differentiate it from the much smaller but related "little grinnell", or Lord Howe silvereye (Zosterops lateralis tephropleurus), a subspecies of the silvereye. This subspecies is still hanging on, but is threatened with extinction.

<i>Zosterops</i> genus of birds

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.

Pied currawong Medium-sized black passerine bird native to eastern Australia and Lord Howe Island

The pied currawong is a medium-sized black passerine bird native to eastern Australia and Lord Howe Island. One of three currawong species in the genus Strepera, it is closely related to the butcherbirds and Australian magpie of the family Artamidae. Six subspecies are recognised. It is a robust crowlike bird averaging around 48 cm (19 in) in length, black or sooty grey-black in plumage with white undertail and wing patches, yellow irises, and a heavy bill. The male and female are similar in appearance. Known for its melodious calls, the species' name currawong is believed to be of indigenous origin.

Silvereye Species of bird

The silvereye or wax-eye is a very small omnivorous passerine bird of the south-west Pacific. In Australia and New Zealand its common name is sometimes white-eye, but this name is more commonly used to refer to all members of the genus Zosterops, or the entire family Zosteropidae.

White swamphen Extinct species of rail from Lord Howe Island

The white swamphen, also known as the Lord Howe swamphen, Lord Howe gallinule or white gallinule, is an extinct species of rail which lived on Lord Howe Island, east of Australia. It was first encountered when the crews of British ships visited the island between 1788 and 1790, and all contemporary accounts and illustrations were produced during this time. Today, two skins exist: the holotype in the Natural History Museum of Vienna, and another in Liverpool's World Museum. Although historical confusion has existed about the provenance of the specimens and the classification and anatomy of the bird, it is now thought to have been a distinct species endemic to Lord Howe Island and most similar to the Australasian swamphen. Subfossil bones have also been discovered since.

Warbling white-eye Species of bird

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.

White-chested white-eye Species of bird

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 Tasman starling was described in 1836 by John Gould as a species which occurred on both Norfolk Island and Lord Howe Island. In 1928 Australian ornithologist Gregory Mathews recognized that the plumage of the race from Lord Howe Island was much browner and more greyish than the plumage of the Norfolk Island race and split the species into two forms, the Norfolk starling, and the Lord Howe starling. Both subspecies are now extinct, thus so the species.

Lord Howe gerygone Extinct species of bird

The Lord Howe gerygone or Lord Howe gerygone flyeater was a small bird in the family Acanthizidae, brown and greyish in color. Its head was brown apart from a pale grey eye-ring and a grey throat and chin, many parts of the animal varied to the colour of yellow, this being apparent in its bright yellow belly. It made its home in the canopies of the island's forest until the early 20th century. The bird has had a variety of monikers: locally, it was known as the "rain-bird" due to its activity after the rains, or the "pop-goes-the-weasel", due to the similarity of its song to the well-known tune. The bird was endemic to Lord Howe Island in the Tasman Sea. There have been no records of the species since 1928, and it is considered to be extinct. Its extinction is almost certainly due to predation by black rats which were accidentally introduced to the island in 1918 following the shipwreck of the SS Makambo there.
