Granite
Granite () is a coarse-grained (phaneritic) intrusive igneous rock composed mostly of quartz, alkali feldspar, and plagioclase. It forms from magma with a high content of silica and alkali metal oxides that slowly cools and solidifies underground. It is common in the continental crust of Earth, where it is found in igneous intrusions. These range in size from dikes only a few centimeters across to batholiths exposed over hundreds of square kilometers. Granite is typical of a larger family of ''granitic rocks'', or ''granitoids'', that are composed mostly of coarse-grained quartz and feldspars in varying proportions. These rocks are classified by the relative percentages of quartz, alkali feldspar, and plagioclase (the QAPF classification), with true granite representing granitic rocks rich in quartz and alkali feldspar. Most granitic rocks also contain mica or amphibole minerals, though a few (known as leucogranites) contain almost no dark minerals. Granite is nearly alway ...

Short-tailed Shearwater
The short-tailed shearwater or slender-billed shearwater (''Ardenna tenuirostris''; formerly ''Puffinus tenuirostris''), also called yolla or moonbird, and commonly known as the muttonbird in Australia, is the most abundant seabird species in Australian waters, and is one of the few Australian native birds in which the chicks are commercially harvested. It is a migratory species that breeds mainly on small islands in Bass Strait and Tasmania and migrates to the Northern Hemisphere for the boreal summer. Taxonomy This shearwater appears to be related to the sooty and great shearwaters, which are also blunt-tailed, black-billed species, but its precise relationships are obscure (Austin, 1996; Austin ''et al.'', 2004). These are among the larger species of shearwater, which have been moved to a separate genus, ''Ardenna'' based on a phylogenetic analysis of mitochondrial DNA (Penhallurick & Wink, 2004). Ecology Each parent feeds the single chick for 2–3 days and then leaves for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Devils Tower (Tasmania)
Devils Tower comprises two small and rugged granite islands, with a combined area of , in south-eastern Australia. It is part of Tasmania’s Curtis Group, lying in northern Bass Strait between the Furneaux Group and Wilsons Promontory in Victoria. It is a nature reserve. The island was sighted and named by Lieutenant James Grant on 9 December 1800 from the survey brig HMS Lady Nelson. Fauna Recorded breeding seabird species include short-tailed shearwater, fairy prion and common diving-petrel. The metallic skink is present. The island is also used as a regular haul-out site for Australian fur seals.Brothers, Nigel; Pemberton, David; Pryor, Helen; & Halley, Vanessa. (2001).

Curtis Island (Tasmania)
Curtis Island is a granite island, with an area of 150 ha, in south-eastern Australia. It is part of Tasmania’s Curtis Group, lying in northern Bass Strait between the Furneaux Group and Wilsons Promontory in Victoria. It is a nature reserve and has been identified as an Important Bird Area because it supports up to 390,000 breeding pairs of short-tailed shearwaters or Tasmanian muttonbirds. It was named by lieutenant James Grant, sailing on the '' Lady Nelson'', after Sir Roger Curtis, British governor of the Cape of Good Hope, in December 1800. , cited in Bird (2006) Fauna As well as the shearwaters, recorded breeding seabird and wader species include little penguin, fairy prion, Pacific gull and sooty oystercatcher. Reptiles present include white-lipped snake, Bougainville's skink, White's skink and metallic skink.Brothers, Nigel; Pemberton, David; Pryor, Helen; & Halley, Vanessa. (2001).

Metallic Skink
:''"Metallic skink" may also refer to the garden skink (Lampropholis delicata)''. ''Carinascincus metallicus'', the metallic cool-skink or metallic skink is a species of skink in the family Scincidae. It is endemic to Australia, found in southern Victoria, as well as in Tasmania where it is the most widespread and common lizard, occurring on many offshore islands in Bass Strait Bass Strait () is a strait separating the island state of Tasmania from the Australian mainland (more specifically the coast of Victoria, with the exception of the land border across Boundary Islet).

Sooty Oystercatcher
The sooty oystercatcher (''Haematopus fuliginosus'') is a species of oystercatcher. It is a wading bird endemic to Australia and commonly found on its coastline. It prefers rocky coastlines, but will occasionally live in estuaries. All of its feathers are black. It has a red eye, eye ring and bill, and pink legs. Taxonomy John Gould described the sooty oystercatcher in 1845. Its species name is the Latin adjective ''fuliginosus'', "sooty". Two subspecies are recognised, the nominate from the coastline of southern Australia and subspecies ''ophthalmicus'' from northern Australia. The southern subspecies is larger and heavier than the northern. The northern one, with a more yellowish eye ring, is found from the Kimberleys across the top of the country to Mackay in central Queensland. There is considerable overlap, as the southern subspecies has been found up to Cape York. Subspecies ''ophthalmicus'' has been thought distinctive enough to warrant species status and needs further inv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pacific Gull
The Pacific gull (''Larus pacificus'') is a very large gull, native to the coasts of Australia. It is moderately common between Carnarvon in the west, and Sydney in the east, although it has become scarce in some parts of the south-east, as a result of competition from the kelp gull, which has "self-introduced" since the 1940s. Much larger than the ubiquitous silver gull, and nowhere near as common, Pacific gulls are usually seen alone or in pairs, loafing around the shoreline, steadily patrolling high above the edge of the water, or (sometimes) zooming high on the breeze to drop a shellfish or sea urchin onto rocks. Diet The gulls' diet consists of a number various fish species and invertebrates. They frequently consume crabs, most often the species ''Ovalipes australiensis'' and ''Paragrapsus gaimardii.'' They also commonly eat '' Platycephalus bassensis'' (sand flatheads) and cephalapods, both of which are sourced from their regular consumption of waste from fish which hav ...

Common Diving-petrel
The common diving petrel (''Pelecanoides urinatrix''), also known as the smaller diving petrel or simply the diving petrel, is a diving petrel, one of four very similar auk-like small petrels of the southern oceans. It is native to South Atlantic islands and islands of the subantarctic southern Indian Ocean, islands and islets off New Zealand and south-eastern Australian islands. Taxonomy The common diving petrel was formally described in 1788 by the German naturalist Johann Friedrich Gmelin. He placed it with the other petrels in the genus ''Procellaria'' and coined the binomial name ''Procellaria uriatrix''. Gmelin based his description on the "diving petrel" that had been described in 1785 by the English ornithologist John Latham in the second volume of his ''A General Synopsis of Birds''. Latham reported that they were found in great numbers in Queen Charlotte Sound at the northern end of South Island, New Zealand. The common diving petrel is now one of four petrels place ...

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 ...

Wader
245px, A flock of Dunlins and Red knots">Red_knot.html" ;"title="Dunlins and Red knot">Dunlins and Red knots Waders or shorebirds are birds of the order Charadriiformes commonly found wikt:wade#Etymology 1, wading along shorelines and mudflats in order to foraging, forage for food crawling or burrowing in the mud and sand, usually small arthropods such as aquatic insects or crustaceans. The term "wader" is used in Europe, while "shorebird" is used in North America, where "wader" may be used instead to refer to long-legged wading birds such as storks and herons. There are about 210 species of wader, most of which live in wetland or coastal environments. Many species of Arctic and temperate regions are strongly migratory, but tropical birds are often resident, or move only in response to rainfall patterns. Some of the Arctic species, such as the little stint, are amongst the longest distance migrants, spending the non- breeding season in the southern hemisphere. Many of the s ...

Hectare
The hectare (; SI symbol: ha) is a non-SI metric unit of area equal to a square with 100-metre sides (1 hm2), or 10,000 m2, and is primarily used in the measurement of land. There are 100 hectares in one square kilometre. An acre is about and one hectare contains about . In 1795, when the metric system was introduced, the ''are'' was defined as 100 square metres, or one square decametre, and the hectare ("hecto-" + "are") was thus 100 ''ares'' or km2 (10,000 square metres). When the metric system was further rationalised in 1960, resulting in the International System of Units (), the ''are'' was not included as a recognised unit. The hectare, however, remains as a non-SI unit accepted for use with the SI and whose use is "expected to continue indefinitely". Though the dekare/decare daa (1,000 m2) and are (100 m2) are not officially "accepted for use", they are still used in some contexts. Description The hectare (), although not a unit of SI, i ...

Seabird
Seabirds (also known as marine birds) are birds that are adapted to life within the marine environment. While seabirds vary greatly in lifestyle, behaviour and physiology, they often exhibit striking convergent evolution, as the same environmental problems and feeding niches have resulted in similar adaptations. The first seabirds evolved in the Cretaceous period, and modern seabird families emerged in the Paleogene. In general, seabirds live longer, breed later and have fewer young than other birds do, but they invest a great deal of time in their young. Most species nest in colonies, which can vary in size from a few dozen birds to millions. Many species are famous for undertaking long annual migrations, crossing the equator or circumnavigating the Earth in some cases. They feed both at the ocean's surface and below it, and even feed on each other. Seabirds can be highly pelagic, coastal, or in some cases spend a part of the year away from the sea entirely.
