Jacquemart Island
Jacquemart Island, one of the islets surrounding Campbell Island in New Zealand, lies south of Campbell Island and is the southernmost island of New Zealand. The name commemorates Captain J. Jacquemart, of the vessel FRWS ''Vire'', that supported the French 1874 Transit of Venus Expedition to Campbell Island. Geography Jacquemart Island consists of a stack with an area of , being about in length by in width and surrounded by precipitous cliffs at least high at their lowest. Its highest point is about asl. It is an eroded remnant of basaltic lavas originally laid down on a sedimentary base. Because of its inaccessibility from the sea, the first visit by humans to the island did not take place until 29 December 1980 when a small party of scientists was landed by helicopter on the summit ridge for a 90-minute survey. Subsequent short visits were made in 1984 and 1997.Foggo, M.N.; & Meurk, Colin D. (1981)Notes on a visit to Jacquemart Island in the Campbell Island Group ' ...

Campbell Island Group
The Campbell Islands (or Campbell Island Group) are a group of subantarctic islands, belonging to New Zealand. They lie about 600 km south of Stewart Island. The islands have a total area of , consisting of one big island, Campbell Island (), and several small islets, notably Dent Island (), Isle de Jeanette Marie (), Folly Island (or Folly Islands), Jacquemart Island (), and Monowai Island (also known as Lion Rock, ). Ecologically, they are part of the Antipodes Subantarctic Islands tundra ecoregion. The islands are one of five subantarctic island groups collectively designated as a World Heritage Site by UNESCO. Geography * Campbell Island / Motu Ihupuku () * Dent Island () * Jacquemart Island () * Folly Island or Folly Islands The islands are relatively flat; due to tectonic pressure, however, there are mountains in the centre of each island. A sea stack at the southern tip of Jacquemart Island is – with the exception of the country's Antarctic claims – New Z ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brown Skua
The brown skua (''Stercorarius antarcticus''), also known as the Antarctic skua, subantarctic skua, southern great skua, southern skua, or hākoakoa (Māori), is a large seabird that breeds in the subantarctic and Antarctic zones and moves further north when not breeding. Its taxonomy is highly complex and a matter of dispute, with some splitting it into two or three species: Falkland skua (''S. antarcticus''), Tristan skua (''S. hamiltoni''), and subantarctic skua (''S. lönnbergi''). To further confuse, it hybridizes with both the south polar and Chilean skuas, and the entire group has been considered to be a subspecies of the great skua, a species otherwise restricted to the Northern Hemisphere. Diet It feeds on fish (often via kleptoparasitism), penguin chicks and other seabirds, small mammals, eggs and carrion. Description This is the heaviest species of skua and rivals the largest gulls, the great black-backed gull and glaucous gull, as the heaviest species in the ...

Introduced Species
An introduced species, alien species, exotic species, adventive species, immigrant species, foreign species, non-indigenous species, or non-native species is a species living outside its native distributional range, but which has arrived there by human activity, directly or indirectly, and either deliberately or accidentally. Non-native species can have various effects on the local ecosystem. Introduced species that become established and spread beyond the place of introduction are considered naturalized. The process of human-caused introduction is distinguished from biological colonization, in which species spread to new areas through "natural" (non-human) means such as storms and rafting. The Latin expression neobiota captures the characteristic that these species are ''new'' biota to their environment in terms of established biological network (e.g. food web) relationships. Neobiota can further be divided into neozoa (also: neozoons, sing. neozoon, i.e. animals) and neophyt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Campbell Snipe
The Campbell snipe (''Coenocorypha aucklandica perseverance''), also known as the Campbell Island snipe, is a rare subspecies of the Subantarctic snipe, endemic to Campbell Island, a subantarctic island south of New Zealand in the Southern Ocean. It was not formally described until January 2010.Miskelly & Baker (2010a, b). The subspecific name alludes to the name of the sealing brig ''Perseverance'', captained by Frederick Hasselborough, that discovered Campbell Island in 1810, and which probably inadvertently introduced rats to the island when it was wrecked there in 1828.DOC media release (2010). History The existence of the Campbell snipe was unknown until 1997 when, during a search for the Campbell teal, there was the chance discovery of a small population on an almost inaccessible rock, Jacquemart Island. Thus there is not much information about it and it remains one of the least known birds in the world.Miskelly & Fraser (2006). Austral snipe are extinct on the mainla ...

Campbell Teal
The Campbell teal or Campbell Island teal (''Anas nesiotis'') is a small, flightless, nocturnal species of dabbling duck of the genus ''Anas'' endemic to the Campbell Island group of New Zealand. It is sometimes considered conspecific with the brown teal. The plumage is similar to that of the Auckland teal, dark sepia with the head and back tinged with green iridescence, and a chestnut breast on the male, with the female dark brown all over. Its natural habitat is tussock grassland dominated by '' Poa'' tussock grass, ferns and megaherbs. The species also uses the burrows and pathways of petrel species that nest on the islands. They are apparently territorial in the wild, and probably feed on amphipods and insects. The IUCN classifies it as vulnerable. Conservation left The Campbell teal was once found on Campbell Island, but was driven to extinction there by the introduction of Norway Rats (which ate their eggs and chicks), and was for a while presumed extinct. In 1975 it was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Important Bird Area
An Important Bird and Biodiversity Area (IBA) is an area identified using an internationally agreed set of criteria as being globally important for the conservation of bird populations. IBA was developed and sites are identified by BirdLife International. There are over 13,000 IBAs worldwide. These sites are small enough to be entirely conserved and differ in their character, habitat or ornithological importance from the surrounding habitat. In the United States the Program is administered by the National Audubon Society. Often IBAs form part of a country's existing protected area network, and so are protected under national legislation. Legal recognition and protection of IBAs that are not within existing protected areas varies within different countries. Some countries have a National IBA Conservation Strategy, whereas in others protection is completely lacking.

Novoplectron
''Novoplectron'' is a monotypic genus of cave wētā in the family Rhaphidophoridae, endemic to the Chatham Islands. Cave wētā are nocturnal, wingless crickets that occupy humid habitats. ''Novoplectron'' wētā generally live under stones and in burrows of seabirds, such as broad-billed prions, mutton birds and storm petrels. Distribution & Taxonomy The genus ''Novoplectron'' have only been recorded on the Chatham Islands (a group of offshore islands of New Zealand). These wētā exist alongside '' Talitropsis crassicruris,'' another New Zealand endemic species, on Mangere, Pitt, Rangatira and The Sisters islands. However, there is an absence of ''Novoplectron'' wētā on the Chatham main island. (See distribution map https://wetageta.massey.ac.nz/Text%20files/NOVOPLECTRON2014.html). Several wētā specimens from the genus '' Pleioplectron'' were collected from the Chatham Islands in 1958. After examining them, Richards discovered that the Chatham Island endemic speci ...

Common Starling
The common starling or European starling (''Sturnus vulgaris''), also known simply as the starling in Great Britain and Ireland, is a medium-sized passerine bird in the starling family, Sturnidae. It is about long and has glossy black plumage with a metallic sheen, which is speckled with white at some times of year. The legs are pink and the bill is black in winter and yellow in summer; young birds have browner plumage than the adults. It is a noisy bird, especially in communal roosts and other gregarious situations, with an unmusical but varied song. Its gift for mimicry has been noted in literature including the ''Mabinogion'' and the works of Pliny the Elder and William Shakespeare. The common starling has about 12 subspecies breeding in open habitats across its native range in temperate Europe and across the Palearctic to western Mongolia, and it has been introduced to Australia, New Zealand, Canada, the United States, Mexico, Argentina, South Africa and Fiji.

New Zealand Pipit
The New Zealand pipit (''Anthus novaeseelandiae'') is a fairly small passerine bird of open country in New Zealand and outlying islands. It belongs to the pipit genus ''Anthus'' in the family Motacillidae. It was formerly lumped together with the Richard's, African, Mountain and Paddyfield pipits in a single species: Richard's pipit, ''Anthus novaeseelandiae''. Many authors split the Australasian pipit further into two species: Australian pipit (''Anthus australis'') in Australia and New Guinea and New Zealand pipit (''Anthus novaeseelandiae''), also called pihoihoi, in New Zealand. Description It is a slender bird, 16 to 19 cm long, and weighs about 40 grams. The plumage is pale brown above with dark streaks. The underparts are pale with streaks on the breast. There is a pale stripe over the eye and dark malar and moustachial stripes. The long tail has white outer-feathers and is often wagged up and down. The legs are long and pinkish-brown while the bill is slender ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
