Gallirallus Australis -Willowbank Wildlife Reserve, Christchurch, New Zealand-8
''Gallirallus'' is a genus of Rallidae, rails that live in the Australasian-Pacific region. The genus is characterised by an ability to colonise relatively small and isolated islands and thereafter to evolve flightless forms, many of which became extinct following Polynesian settlement. Taxonomy Following recent taxonomic revisions, there is only one known extant species in this genus along with several extinct species of dubious classification, with all other species being moved to ''Hypotaenidia'', ''Cabalus'', or ''Calayan rail, Aptenorallus''. Description Many of the rails, including the well-known weka of New Zealand, are flightless or nearly so. Many of the resultant flightless island endemism, endemics became extinct after the arrival of humans, which hunted these birds for food, introduced novel predator (biology), predators like rats, dogs or pigs, and upset the local ecosystems. A common Polynesian language, Polynesian name of these rails, mainly relatives of ''G. p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Weka
The weka, also known as the Māori hen or woodhen (''Gallirallus australis'') is a flightless bird species of the rail family. It is endemic to New Zealand. It is the only extant member of the genus ''Gallirallus''. Four subspecies are recognized but only two (northern/southern) are supported by genetic evidence. The weka are sturdy brown birds, about the size of a chicken. As omnivores, they feed mainly on invertebrates and fruit. Weka usually lay eggs between August and January; both sexes help to incubate. Description Weka are large rails. They are predominantly rich brown mottled with black and grey; the brown shade varies from pale to dark depending on subspecies. The male is the larger sex at in length and in weight. Females measure in length and weigh . The reduced wingspan ranges from . The relatively large, reddish-brown beak is about long, stout and tapered, and used as a weapon. The pointed tail is near-constantly being flicked, a sign of unease characteristic of ...

English Language
English is a West Germanic language of the Indo-European language family, with its earliest forms spoken by the inhabitants of early medieval England. It is named after the Angles, one of the ancient Germanic peoples that migrated to the island of Great Britain. Existing on a dialect continuum with Scots, and then closest related to the Low Saxon and Frisian languages, English is genealogically West Germanic. However, its vocabulary is also distinctively influenced by dialects of France (about 29% of Modern English words) and Latin (also about 29%), plus some grammar and a small amount of core vocabulary influenced by Old Norse (a North Germanic language). Speakers of English are called Anglophones. The earliest forms of English, collectively known as Old English, evolved from a group of West Germanic (Ingvaeonic) dialects brought to Great Britain by Anglo-Saxon settlers in the 5th century and further mutated by Norse-speaking Viking settlers starting in the 8th and 9th ...

Extinct In The Wild
A species that is extinct in the wild (EW) is one that has been categorized by the International Union for Conservation of Nature as known only by living members kept in captivity or as a naturalized population outside its historic range due to massive habitat loss. Examples Examples of species and subspecies that are extinct in the wild include: *Alagoas curassow (last unconfirmed sighting reported in the late 1980s, listed extinct in the wild since 1994) *Beloribitsa * Cachorrito de charco palmal (last seen in 1994, listed extinct in the wild since 1996) * Christmas Island blue-tailed skink (listed extinct in the wild since 2014) *Dabry's sturgeon (listed extinct in the wild since 2022) * Escarpment cycad (listed extinct in the wild since 2006) *Franklinia (last seen in 1803, listed extinct in the wild since 1998) *Golden skiffia (listed extinct in the wild since 1996) *Guam kingfisher (listed extinct in the wild since 1986) *Hawaiian crow or ʻalalā (last seen in 2002, li ...

Guam Rail
The Guam rail (''Hypotaenidia owstoni'') is a species of flightless bird, endemic to the United States territory of Guam, where it is known locally as the ''Ko'ko bird. The Guam rail disappeared from southern Guam in the early 1970s and was extirpated from the entire island by the late 1980s. This species is now being bred in captivity by the Division of Aquatic and Wildlife Resources on Guam and at some mainland U.S. zoos. Since 1995, more than 100 rails have been introduced on the island of Rota in the Commonwealth of the Northern Mariana Islands in an attempt to establish a wild breeding colony. Although at least one chick resulted from these efforts, feral cat predation and accidental deaths have been extremely high. In 2010, 16 birds were released onto Cocos Island, with 12 more being introduced in 2012. In 2019, the species became only the second bird after the California condor to be reclassified by the IUCN from extinct in the wild to critically endangered. Backgrou ...

EBird
eBird is an online database of bird observations providing scientists, researchers and amateur naturalists with real-time data about bird distribution and abundance. Originally restricted to sightings from the Western Hemisphere, the project expanded to include New Zealand in 2008, and again expanded to cover the whole world in June 2010. eBird has been described as an ambitious example of enlisting amateurs to gather data on biodiversity for use in science. eBird is an example of crowdsourcing, and has been hailed as an example of democratizing science, treating citizens as scientists, allowing the public to access and use their own data and the collective data generated by others. History and purpose Launched in 2002 by the Cornell Lab of Ornithology at Cornell University and the National Audubon Society, eBird gathers basic data on bird abundance and distribution at a variety of spatial and temporal scales. It was mainly inspired by the ÉPOQ database, created by Jacque ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Clements Checklist Of Birds Of The World
''The Clements Checklist of Birds of the World'' is a book by Jim Clements which presents a list of the bird species of the world. The most recent printed version is the sixth edition (2007), but has been updated yearly, the last version in 2022, and is published by Cornell University Press. Previous editions were published by the author's own imprint, Ibis Publishing.
