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] |

Feral
A feral () animal or plant is one that lives in the wild but is descended from domesticated individuals. As with an introduced species, the introduction of feral animals or plants to non-native regions may disrupt ecosystems and has, in some cases, contributed to extinction of indigenous species. The removal of feral species is a major focus of island restoration. Animals A feral animal is one that has escaped from a domestic or captive status and is living more or less as a wild animal, or one that is descended from such animals. Other definitions include animals that have changed from being domesticated to being wild, natural, or untamed. Some common examples of animals with feral populations are horses, dogs, goats, cats, rabbits, camels, and pigs. Zoologists generally exclude from the feral category animals that were genuinely wild before they escaped from captivity: neither lions escaped from a zoo nor the white-tailed eagles re-introduced to the UK are regarded as fera ...

Campbell Albatross
The Campbell albatross (''Thalassarche impavida'') or Campbell mollymawk, is a medium-sized mollymawk in the albatross family. It breeds only on Campbell Island and the associated islet of Jeanette Marie, in a small New Zealand island group in the South Pacific. It is sometimes considered a subspecies of the black-browed albatross. It is a medium-sized black and white albatross with a pale yellow iris. Taxonomy Mollymawks are a type of albatross that belong to family Diomedeidae of the order Procellariiformes, along with shearwaters, fulmars, storm petrels, and diving petrels. They share certain identifying features. First, they have nasal passages that attach to the upper bill called naricorns, although the nostrils on the albatross are on the sides of the bill. The bills of Procellariiformes are also unique in that they are split into between seven and nine horny plates. Finally, they produce a stomach oil made up of wax esters and triglycerides that is stored in the proventric ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Black-browed Albatross
The black-browed albatross (''Thalassarche melanophris''), also known as the black-browed mollymawk,Robertson, C. J. R. (2003) is a large seabird of the albatross family Diomedeidae; it is the most widespread and common member of its family. Taxonomy Mollymawks are albatrosses in the family Diomedeidae and order Procellariiformes, which also includes shearwaters, fulmars, storm petrels, and diving petrels. These birds share certain identifying features. They have nasal passages that attach to the upper bill called naricorns, although the nostrils on the albatross are on the sides of the bill. The bills of Procellariiformes are also unique in that they are split into between seven and nine horny plates. They produce a stomach oil made up of wax esters and triglycerides that is stored in the proventriculus. This is used against predators as well as being an energy-rich food source for chicks and also for the adults during their long flights. The albatross also has a salt gland a ...

Light-mantled Albatross
The light-mantled albatross (''Phoebetria palpebrata'') also known as the grey-mantled albatross or the light-mantled sooty albatross, is a small albatross in the genus ''Phoebetria'', which it shares with the sooty albatross. The light-mantled albatross was first described as ''Phoebetria palpebrata'' by Johann Reinhold Forster, in 1785, based on a specimen from south of the Cape of Good Hope. Physiology Light-mantled albatrosses share some identifying features with other Procellariiformes. They have nasal tubes on the upper bill called naricorns, though with albatrosses these are on the sides of the upper mandible rather than the top. They also have a salt gland above the nasal passage which excretes a concentrated saline solution to maintain osmotic balance, due to the amount of seawater imbibed. The bills of the Procellariiformes are unique in that they are covered with from seven to nine horny plates. These birds produce a stomach oil made up of wax esters and triglycerides ...

Southern Royal Albatross
The southern royal albatross or toroa, (''Diomedea epomophora'') is a large seabird from the albatross family. At an average wingspan of above , it is one of the two largest species of albatross, together with the wandering albatross. Recent studies indicate that the southern royal albatross may, on average, be somewhat larger than the wandering albatross in mass and have a similar wingspan, although other sources indicate roughly similar size for the two species and the wandering species may have a larger average (and maximum) wingspan in some colonies.''CRC Handbook of Avian Body Masses, 2nd Edition'' by John B. Dunning Jr. (Editor). CRC Press (2008), . Taxonomy Albatrosses belong to family Diomedeidae of the order Procellariiformes, along with shearwaters, fulmars, storm petrels, and diving petrels.

Antipodean Albatross
The Antipodean albatross (''Diomedea antipodensis'') is a large seabird in the albatross family. Antipodean albatrosses are smaller than wandering albatrosses, and breed in predominantly brown plumage, but are otherwise difficult to distinguish from young wanderers (wandering albatrosses grow lighter in color with age, while the Antipodean stays darker). Etymology ''Diomedea antipodensis'' breaks into ''Diomedea'' referring to ''Diomedes'', whose companions turned to birds, and ''antipodensis'', the Latin form of the Antipodes Islands, where they are found. Taxonomy The Antipodean albatross belongs to the order Procellariiformes. Like all members of this order, they have naricorns, tubular nasal passages on their bill. They also have a unique palate with seven to nine bony plates.Robertson, C. J. R. (2003) One of the great albatrosses of the genus ''Diomedea'', it was only distinguished as a subspecies of the wandering albatross in 1992 and recognised by some authorities as a fu ...

Yellow-eyed Penguin
The yellow-eyed penguin (''Megadyptes antipodes''), known also as hoiho or tarakaka, is a species of penguin endemic to New Zealand. Previously thought closely related to the little penguin (''Eudyptula minor''), molecular research has shown it more closely related to penguins of the genus ''Eudyptes''. Like most other penguins, it is mainly piscivorous. The species breeds along the eastern and south-eastern coastlines of the South Island of New Zealand, as well as Stewart Island, Auckland Islands, and Campbell Islands. Colonies on the Otago Peninsula are a popular tourist venue, where visitors may closely observe penguins from hides, trenches, or tunnels. On the New Zealand mainland, the species has experienced a significant decline over the past 20 years. On the Otago Peninsula, numbers have dropped by 75% since the mid-1990s and population trends indicate the possibility of local extinction in the next 20 to 40 years. While the effect of rising ocean temperatures is stil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Southern Rockhopper Penguin
The southern rockhopper penguin group (''Eudyptes chrysocome''), is a species of rockhopper penguin, that is sometimes considered distinct from the northern rockhopper penguin. It occurs in subantarctic waters of the western Pacific and Indian Oceans, as well as around the southern coasts of South America. Taxonomy In 1743 the English naturalist George Edwards included an illustration and a description of the southern rockhopper penguin in the first volume of his ''A Natural History of Uncommon Birds''. Edwards based his hand-coloured etching on a preserved specimen owned by Peter Collinson. When in 1758 the Swedish naturalist Carl Linnaeus updated his ''Systema Naturae'' for the tenth edition, he placed the southern rockhopper penguin with the red-billed tropicbird in the genus ''Phaethon''. Linnaeus included a brief description, coined the binomial name ''Phaethon demersus'' and cited Edwards' work. The use of Linnaeus' binomial name was not adopted by later ornithologists, ...

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] |
