Trumpeter Islets
The Trumpeter Islets comprise a group of two unpopulated islets, with a combined area of about a hectare, located close to the south-western coast of Tasmania, Australia. Situated some where the mouth of Port Davey meets the Southern Ocean, the island is part of the Trumpeter Islets Group, and comprises part of the Southwest National Park and the Tasmanian Wilderness World Heritage Site. Fauna The islets are part of the Port Davey Islands Important Bird Area, so identified by BirdLife International because of its importance for breeding seabirds. Recorded breeding seabird and wader species are the little penguin (1000 pairs), short-tailed shearwater (1000 pairs), Pacific gull, silver gull, sooty oystercatcher, black-faced cormorant and Caspian tern.

Landsat
The Landsat program is the longest-running enterprise for acquisition of satellite imagery of Earth. It is a joint NASA / USGS program. On 23 July 1972, the Earth Resources Technology Satellite was launched. This was eventually renamed to Landsat 1 in 1975. The most recent, Landsat 9, was launched on 27 September 2021. The instruments on the Landsat satellites have acquired millions of images. The images, archived in the United States and at Landsat receiving stations around the world, are a unique resource for global change research and applications in agriculture, cartography, geology, forestry, regional planning, surveillance and education, and can be viewed through the U.S. Geological Survey (USGS) "EarthExplorer" website. Landsat 7 data has eight spectral bands with spatial resolutions ranging from ; the temporal resolution is 16 days. Landsat images are usually divided into scenes for easy downloading. Each Landsat scene is about 115 miles long and 115 miles wide (or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Islands Of South West Tasmania
An island (or isle) is an isolated piece of habitat that is surrounded by a dramatically different habitat, such as water. Very small islands such as emergent land features on atolls can be called islets, skerries, cays or keys. An island in a river or a lake island may be called an eyot or ait, and a small island off the coast may be called a holm. Sedimentary islands in the Ganges delta are called chars. A grouping of geographically or geologically related islands, such as the Philippines, is referred to as an archipelago. There are two main types of islands in the sea: continental and oceanic. There are also artificial islands, which are man-made. Etymology The word ''island'' derives from Middle English ''iland'', from Old English ''igland'' (from ''ig'' or ''ieg'', similarly meaning 'island' when used independently, and -land carrying its contemporary meaning; cf. Dutch ''eiland'' ("island"), German ''Eiland'' ("small island")). However, the spelling of the word ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Islands Of Tasmania
Tasmania is the smallest and southernmost state of Australia. The Tasmanian mainland itself is an island, with an area of - 94.1% of the total land area of the state. The other islands have a combined area of , for a cumulative total of 99.75% of the state. About 1000 smaller islands make up the remaining of total land area. Classification structure A considerable number of Tasmanian islands are identified as being in island groups, including the Breaksea, Furneaux, Hogan, Hunter, Kent, Maatsuyker, Mutton Bird, New Year, Swainson, Trumpeter, and Waterhouse groups. Regions Similar to Regions of Tasmania the islands are generally distinguished by the coast that they are adjacent to, as well as Bass Strait - the main separation from the mainland state of Victoria. Five regions are aligned to the north coast and Bass Strait - ''North West Islands'' (including King Island), ''North Coast Islands'', ''North Bass Strait Islands'', ''Furneaux Islands'', and ''North East Islands' ...

Caspian Tern
The Caspian tern (''Hydroprogne caspia'') is a species of tern, with a subcosmopolitan but scattered distribution. Despite its extensive range, it is monotypic of its genus, and has no accepted subspecies. The genus name is from Ancient Greek ''hudros'', "water", and Latin ''progne'', "swallow". The specific ''caspia'' is from Latin and, like the English name, refers to the Caspian Sea. Description It is the world's largest tern with a length of , a wingspan of and a weight of . Adult birds have black legs, and a long thick red-orange bill with a small black tip. They have a white head with a black cap and white neck, belly, and tail. The upper wings and back are pale grey; the underwings are pale with dark primary feathers. In-flight, the tail is less forked than other terns, and wingtips are black on the underside. In winter, the black cap is still present (unlike many other terns), but with some white streaking on the forehead. The call is a loud heron-like croak. Distribu ...

Black-faced Cormorant
The black-faced cormorant (''Phalacrocorax fuscescens''), also known as the black-faced shag, is a medium-sized member of the cormorant family. Upperparts, including facial skin and bill, are black, with white underparts. It is endemic to coastal regions of southern Australia. Description Like other cormorant species, the black-faced cormorant is a large aquatic bird, with a long hooked bill, webbed feet, and monochromatic plumage. This is one of the largest cormorants found in south-western Australia and has pied plumage with the upper half of its body black and the undersides white. Its face is naked and black, hence the "black-faced" name, and the tail, feet, and thighs are also black. The back feathers are glossy, and its bill is dark grey with a prominent hook at the tip. It has blue-green eyes. When flying, it holds its head level or lower than its body and holds its wings in a cross-shape like most cormorants. Species that are similar in appearance include the pied c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Silver Gull
The silver gull (''Chroicocephalus novaehollandiae'') is the most common gull of Australia. It has been found throughout the continent, but particularly at or near coastal areas. It is smaller than the Pacific gull (''Larus pacificus''), which also lives in Australia. The silver gull should not be confused with the herring gull, which is called "silver gull" in many other languages (scientific name ''Larus argentatus'', German ''Silbermöwe'', French ''Goéland argenté'', Dutch ''zilvermeeuw''), but is a much larger, robust gull with no overlap in range. Taxonomy It has traditionally been placed in the genus ''Larus'', as is the case with many gulls, but is now placed in the genus ''Chroicocephalus''. Hartlaub's gull (''C. hartlaubii'') of South Africa was formerly sometimes considered to be subspecies of the silver gull. There are three subspecies: * ''C. n. forsteri'' ( Mathews, 1912) – north and northeast Australia, New Caledonia, Loyalty Islands * ''C. n. novaehollan ...

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 ...

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] |
Little Penguin
The little penguin (''Eudyptula minor'') is a species of penguin from New Zealand. They are commonly known as little blue penguins or blue penguins owing to their slate-blue plumage and are also known by their Māori name . The Australian little penguin (''Eudyptula novaehollandiae'') from Australia and the Otago region of New Zealand is considered a separate species by a 2016 study and a 2019 study. Taxonomy The little penguin was first described by German naturalist Johann Reinhold Forster in 1781. Several subspecies are known, but a precise classification of these is still a matter of dispute. The holotypes of the subspecies ''E. m. variabilis'' and ''Eudyptula minor chathamensis'' are in the collection of the Museum of New Zealand Te Papa Tongarewa. The white-flippered penguin (''E. m. albosignata'' or ''E. m. minor morpha albosignata'') is currently considered by most taxonomists to be a colour morph or subspecies of ''Eudyptula minor.''
