Motunau Island
Motunau Island is a small, , island nature reserve lying off the coast of New Zealand's South Island, at the northern end of Pegasus Bay, south of the mouth of the Motunau River. The reserve is managed by the Department of Conservation and access is by permit only. Description About long by wide, the island has steep sides rising to a distinctive flat top some above sea level. Geologically, it consists of Tertiary rocks, capped with loess and gravels, and surrounded by eroding cliffs and wave-cut reefs. The soils are extensively burrowed by nesting seabirds. Flora and fauna The island is an important site for seabirds. In 1967, it was the breeding site of an estimated 23,000 individual birds. It is home to a colony of 5,000 white-flippered penguins. Other birds recorded as breeding there include white-faced storm petrels, sooty shearwaters, fairy prions, variable oystercatchers and white-fronted terns. The island has the only colony of white-faced storm petrels found along ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bay Of Plenty
The Bay of Plenty ( mi, Te Moana-a-Toi) is a region of New Zealand, situated around a bight of the same name in the northern coast of the North Island. The bight stretches 260 km from the Coromandel Peninsula in the west to Cape Runaway in the east. The Bay of Plenty Region, governed by the Bay of Plenty Regional Council, incorporates several large islands in the bay, in addition to the mainland area. Called ''Te Moana-a-Toi'' (the Sea of Toi) in the Māori language after Toi, an early ancestor, the name 'Bay of Plenty' was bestowed by James Cook in 1769 when he noticed the abundant food supplies at several Māori villages there, in stark contrast to observations he had made earlier in Poverty Bay. History According to local Māori traditions, the Bay of Plenty was the landing point of several migration canoes that brought Māori settlers to New Zealand. These include the ''Mātaatua'', ''Nukutere'', ''Tākitimu'', '' Arawa'' and ''Tainui'' canoes. Many of the de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bird Colony
A bird colony is a large congregation of individuals of one or more species of bird that nest or roost in proximity at a particular location. Many kinds of birds are known to congregate in groups of varying size; a congregation of nesting birds is called a breeding colony. Colonial nesting birds include seabirds such as auks and albatrosses; wetland species such as herons; and a few passerines such as weaverbirds, certain blackbirds, and some swallows. A group of birds congregating for rest is called a communal roost. Evidence of colonial nesting has been found in non- neornithine birds ( Enantiornithes), in sediments from the Late Cretaceous (Maastrichtian) of Romania. Variations on colonial nesting in birds Approximately 13% of all bird species nest colonially. Nesting colonies are very common among seabirds on cliffs and islands. Nearly 95% of seabirds are colonial, leading to the usage, seabird colony, sometimes called a rookery. Many species of terns nest in colonie ...

Mirounga Leonina
The southern elephant seal (''Mirounga leonina'') is one of two species of elephant seals. It is the largest member of the clade Pinnipedia and the order Carnivora, as well as the largest extant marine mammal that is not a cetacean. It gets its name from its massive size and the large proboscis of the adult male, which is used to produce very loud roars, especially during the breeding season. A bull southern elephant seal is about 40% heavier than a male northern elephant seal (''Mirounga angustirostris''), twice as heavy as a male walrus (''Odobenus rosmarus''), and 6–7 times heavier than the largest living mostly-terrestrial carnivoran, the polar bear (''Ursus maritimus'') and the Kodiak bear (''Ursus arctos middendorffi''),. Taxonomy The southern elephant seal was one of the many species originally described by Swedish zoologist Carl Linnaeus in the landmark 1758 10th edition of his '' Systema Naturae'', where it was given the binomial name of ''Phoca leonina''.

Hauling-out
Hauling-out is a behaviour associated with pinnipeds (true seals, sea lions, fur seals and walruses) temporarily leaving the water. Hauling-out typically occurs between periods of foraging activity. Rather than remain in the water, pinnipeds haul-out onto land or sea-ice for reasons such as reproduction and rest. Hauling-out is necessary in seals for mating (with the exception of the Baikal seal) and giving birth (although a distinction is generally made between reproductive aggregations, termed "rookeries", and non-reproductive aggregations, termed "haul-outs"). Other benefits of hauling-out may include predator avoidance, thermoregulation, social activity, parasite reduction and rest. There is much variation in haul-out patterns among different seal species.Hoelzel, A. Rus. (2002). ''Marine Mammal Biology: An Evolutionary Approach''. Blackwell Publishing. . p. 197. Haul-out sites may be segregated by age and sex within the same species. Many species of pinniped have only a fe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arctocephalus Forsteri
''Arctocephalus forsteri'' (common names include the Australasian fur seal, South Australian fur seal, New Zealand fur seal, Antipodean fur seal, or long-nosed fur seal) is a species of fur seal found mainly around southern Australia and New Zealand. The name ''New Zealand fur seal'' is used by English speakers in New Zealand; ''kekeno'' is used in the Māori language. , the common name long-nosed fur seal has been proposed for the population of seals inhabiting Australia. Although the Australian and New Zealand populations show some genetic differences, their morphologies are very similar, and thus they remain classed as a single species. After the arrival of humans in New Zealand, and particularly after the arrival of Europeans in Australia and New Zealand, hunting reduced the population to near-extinction. Description Males have been reported as large as 160 kg; their average weight is about 126 kg.Harcourt, R.G., (2001)"Advances in New Zealand mammalogy 1990–20 ...

Leiolopisma
''Leiolopisma'' is a genus of skinks. Most species occur in the region of New Caledonia-New Zealand, and they are related to other genera from that general area, such as ''Emoia''; these and others form the ''Eugongylus'' group. One living and two extinct taxa represent a clade endemic to the Mascarenes.(Austin & Arnold 2006) Species *'' Leiolopisma alazon'' Zug, 1985 - Lauan ground skink, Ono-i-Lau ground skink *'' Leiolopisma ceciliae'' Arnold & Bour, 2008 - extinct - Réunion giant skink *'' Leiolopisma fasciolare'' (Girard, 1858) *''Leiolopisma telfairii'' (Desjardin, 1831) - Round Island skink, Telfair's skink An undescribed extinct taxon from Réunion was close to ''L. mauritiana'' (Austin & Arnold 2006). These two were formerly separated in ''Didosaurus''. David Day (1979), in Vanished Species, described the Reunion skink as small and fast moving but completely unafraid of humans. Individuals would climb on observer's legs. Efforts to maintain the species in capti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lizard
Lizards are a widespread group of squamate reptiles, with over 7,000 species, ranging across all continents except Antarctica, as well as most oceanic island chains. The group is paraphyletic since it excludes the snakes and Amphisbaenia although some lizards are more closely related to these two excluded groups than they are to other lizards. Lizards range in size from chameleons and geckos a few centimeters long to the 3-meter-long Komodo dragon. Most lizards are quadrupedal, running with a strong side-to-side motion. Some lineages (known as "legless lizards"), have secondarily lost their legs, and have long snake-like bodies. Some such as the forest-dwelling ''Draco'' lizards are able to glide. They are often territorial, the males fighting off other males and signalling, often with bright colours, to attract mates and to intimidate rivals. Lizards are mainly carnivorous, often being sit-and-wait predators; many smaller species eat insects, while the Komodo eats mammals a ...

Otago Peninsula
The Otago Peninsula ( mi, Muaūpoko) is a long, hilly indented finger of land that forms the easternmost part of Dunedin, New Zealand. Volcanic in origin, it forms one wall of the eroded valley that now forms Otago Harbour. The peninsula lies south-east of Otago Harbour and runs parallel to the mainland for 20 km, with a maximum width of 9 km. It is joined to the mainland at the south-west end by a narrow isthmus about 1.5 km wide. The suburbs of Dunedin encroach onto the western end of the peninsula, and seven townships and communities lie along the harbourside shore. The majority of the land is sparsely populated and occupied by steep open pasture. The peninsula is home to many species of wildlife, notably seabirds, pinnipeds, and penguins; several ecotourism businesses operate in the area. Geography The peninsula was formed at the same time as the hills facing it across the harbour, as part of the large, long-extinct, Dunedin Volcano. Several of the peninsula' ...

Cook Strait
Cook Strait ( mi, Te Moana-o-Raukawa) separates the North and South Islands of New Zealand. The strait connects the Tasman Sea on the northwest with the South Pacific Ocean on the southeast. It is wide at its narrowest point,McLintock, A H, Ed. (1966''Cook Strait''from An Encyclopaedia of New Zealand, updated 18-Sep-2007. Note: This is the distance between the North Island and Arapaoa Island; some sources give a slightly larger reading of around , that between the North Island and the South Island. and is considered one of the most dangerous and unpredictable waters in the world. Regular ferry services run across the strait between Picton in the Marlborough Sounds and Wellington. The strait is named after James Cook, the first European commander to sail through it, in 1770. In Māori it is named ''Te Moana-o-Raukawa'', which means ''The Sea of Raukawa''. Raukawa is a type of woody shrub native to New Zealand. History Approximately 18,000 years ago during the Last Gla ...

White-fronted Tern
The white-fronted tern (''Sterna striata''), also known as tara, sea swallow, black-billed tern, kahawai bird, southern tern, or swallow tail, was first described by Johann Friedrich Gmelin in 1789. A medium-sized tern with an all-white body including underwing and forked tail, with grey hues on the over the upper side of the wing. In breeding adults a striking black cap covers the head from forehead to nape, leaving a small white strip above the black bill. This is the most abundant tern in New Zealand. It can be observed feeding on shoaling fish along the entire coastline and many of the smaller outlying islands. Breeding occurs from October to January on rocky cliffs, offshore islands and along the coast where pairs will nest on shingle, sand, shell or rock. Flocks may contain hundreds of breeding pairs that will nest in close proximity to one another. Large numbers of juveniles and some adults migrate to the south-east coast of Australia and parts of Tasmania in the autumn, wi ...

Variable Oystercatcher
The variable oystercatcher (''Haematopus unicolor'') is a species of wader in the family Haematopodidae. It is endemic to New Zealand. The Maori name is torea-pango. They are also known as 'red bills'. Description "Variable" refers to the frontal plumage, which ranges from pied through mottled to all black. They are polymorphic meaning they have different genetic variants. These color differences are attributed to the latitude of the habitat, where the northernmost oystercatchers have significantly more white on their bodies than those of southern origin. All Stewart Island variable oystercatchers are black. They have pink legs, an orange eye ring and orange-red beaks. Similar to a needle in shape, the bill is thin and long, and darkens to a deep red color during the breeding season. Males are around 678 grams and females slightly larger at around 724 grams. Length of individuals range from 42 to 47 cm from beak to tail and have a short, sturdy body with a thick neck. Va ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fairy Prion
The fairy prion (''Pachyptila turtur'') is a small seabird with the standard prion plumage of blue-grey upperparts with a prominent dark "M" marking and white underneath. The sexes are alike. This is a small prion of the low subantarctic and subtropic seas. Taxonomy The fairy prion was formally described in 1820 by the German naturalist Heinrich Kuhl under the binomial name ''Procellaria turtur''. It is now placed with the other prions in the genus ''Pachyptila'' that was introduced in 1811 by Johann Karl Wilhelm Illiger. The genus name combines the Ancient Greek ''pakhus '' meaning "dense" or "thick" with ''ptilon'' meaning "feather" or "plumage". The specific epithet ''turtur'' is Latin for "turtle dove". The word comes from the Ancient Greek word meaning "a saw", which is in reference to its serrated edges of its bill.Gotch, A. T. (1995) The fairy prion is a member of the genus ''Pachyptila'', and along with the blue petrel makes up the prions. They in turn are members of ...
