Gulf St Vincent Important Bird Area
The Gulf St Vincent Important Bird Area comprises land extending along the coast of Gulf St Vincent, north of Adelaide, South Australia. Description The Gulf St Vincent Important Bird Area (IBA) is a strip of coastline containing the continuous mudflats along the north and north-east of Gulf St Vincent north of Adelaide. It extends from Ardrossan in the north-west, around the head of the Gulf to the mouth of the Port River and Outer Harbor in Adelaide. The main habitats are intertidal mudflats, mangroves and two large saltworks, with some small coastal wetlands. Much of the IBA adjoins industrial and residential suburbs, especially to the north of Adelaide. Key sites include the Price saltworks, Clinton Conservation Park, Parham, Port Prime, the Dry Creek wetlands and saltworks, Salisbury wetlands, Barker Inlet wetlands, Bolivar Wastewater Treatment Plant, Buckland Park Lake, the Port River mouth, the Torrens Island complex, and Outer Harbor. Many birds move between th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South Australia
South Australia (commonly abbreviated as SA) is a States and territories of Australia, state in the southern central part of Australia. With a total land area of , it is the fourth-largest of Australia's states and territories by area, which includes some of the most arid parts of the continent, and with 1.8 million people. It is the fifth-largest of the states and territories by population. This population is the second-most highly centralised in the nation after Western Australia, with more than 77% of South Australians living in the capital Adelaide or its environs. Other population centres in the state are relatively small; Mount Gambier, the second-largest centre, has a population of 26,878. South Australia shares borders with all the other mainland states. It is bordered to the west by Western Australia, to the north by the Northern Territory, to the north-east by Queensland, to the east by New South Wales, to the south-east by Victoria (state), Victoria, and to the s ...

Sewage Treatment
Sewage treatment is a type of wastewater treatment which aims to remove contaminants from sewage to produce an effluent that is suitable to discharge to the surrounding environment or an intended reuse application, thereby preventing water pollution from raw sewage discharges. Sewage contains wastewater from households and businesses and possibly pre-treated Industrial wastewater treatment, industrial wastewater. There are a large number of sewage treatment processes to choose from. These can range from Decentralized wastewater system, decentralized systems (including on-site treatment systems) to large centralized systems involving a network of pipes and pump stations (called sewerage) which convey the sewage to a treatment plant. For cities that have a combined sewer, the sewers will also carry urban runoff (stormwater) to the sewage treatment plant. Sewage treatment often involves two main stages, called primary and secondary treatment, while advanced treatment also incorpo ...

Fairy Tern
The fairy tern (''Sternula nereis'') is a small tern which is native to the southwestern Pacific. It is listed as " Vulnerable" by the IUCN and the New Zealand subspecies is "Critically Endangered". Fairy terns live in colonies along the coastlines and estuaries of Australia, New Zealand, and New Caledonia, feeding largely on small, epipelagic schooling fishes, breeding in areas close to their feeding sites. They have a monogamous mating system, forming breeding pairs in which they mate, nest, and care for offspring. There are three subspecies: * Australian fairy tern, ''Sternula nereis nereis'' ( Gould, 1843) – breeds in Australia * New Caledonian fairy tern, ''Sternula nereis exsul'' ( Mathews, 1912) – breeds in New Caledonia * New Zealand fairy tern / Tara iti, ''Sternula nereis davisae'' ( Mathews & Iredale, 1913) – breeds in northern New Zealand The three subspecies are distinguished by geographical range, and slight morphological differences.

Australasian Bittern
The Australasian bittern (''Botaurus poiciloptilus''), or Matuku-hūrepo in Māori language, Māori, is a stocky, sizeable and elusive heron-like bird native to the Wetland, wetlands of Australia, New Zealand, and New Caledonia.Heather, B. D., & Robertson, H. A. (1996). ''The Field Guide to the Birds of New Zealand''. Penguin Books (NZ) Ltd. It belongs to the bittern subfamily of the heron family Heron, Ardeidae. The Australasian bittern is best known for its cryptic plumage and behaviours, which allows it to blend into the rushes and reeds of its wetland habitats, making it particularly difficult to spot.O’Donnell, C. F. J., Williams, E. M., & Cheyne, J. (2013)Close approaches and acoustic triangulation: techniques for mapping the distribution of booming Australasian bittern (''Botaurus poiciloptilus'') on small wetlands.''Notornis'', ''60'', 279–284. Despite being rarely seen, Australasian bittern males have a distinct "booming" call that can carry long distances. Physicall ...

Silver Gull
The silver gull (''Chroicocephalus novaehollandiae'') is a gull in Oceania. It 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 , French , Dutch ), 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. novaehollandiae'' ( Stephens, ...

Pied Oystercatcher
The pied oystercatcher (''Haematopus longirostris'') is a species of oystercatcher. It is a wading bird native to Australia and commonly found on its coastline. The similar South Island pied oystercatcher (''H. finschi'') occurs in New Zealand. Description The name "oystercatcher" is something of a misnomer for this species, because they seldom eat oysters, which are found mainly on rocky coastlines. Pied oystercatchers frequent sandy coastlines, where they feed mainly on bivalve molluscs, which are prised apart with their specially adapted bill. These adaptations allow the Pied oystercatchers to slip their bills between the ventral edges of these shelled organisms, further allowing them to sever the shells and reach the edible flesh inside. This Australian species is easily recognized by the characteristic 5–8 cm long orange-red beak, slender pink legs and black and white plumage. With the wings extended, a white wing-stripe is also visible. The male and female show ... [...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 Latin ( or ) is a classical language belonging to the Italic languages, Italic branch of the Indo-European languages. Latin was originally spoken by the Latins (Italic tribe), Latins in Latium (now known as Lazio), the lower Tiber area aroun ... 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 ...

Red-capped Plover
The red-capped plover (''Anarhynchus ruficapillus''), also known as the red-capped dotterel, is a small species of plover. It breeds in Australia. This species is closely related to (and sometimes considered conspecific with) the Kentish plover, Javan plover, and white-fronted plover. Description Red-capped plovers have a white forehead and underparts. Their upperparts are mainly grey-brown. Adult males have a rufous or reddish-brown crown and hindneck. Adult females have a paler rufous and grey-brown crown and hindneck, with a pale wikt:lore, loreal stripe. The upperwing of ''Charadrius ruficapillus'' shows dark brown Flight feather#Remiges, remiges (flight feathers) and primary covert feathers with a white wingbar in flight. Its length is 14–16 cm (5.5–6.3 in) and its wingspan is 27–34 cm (10.6–13.4 in); it weighs 35–40 g (1.2–1.4 oz). Breeding plumage shows a red-brown crown and nape with black margins. Non-breeding plumage is duller and lacks the black ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Banded Stilt
The banded stilt (''Cladorhynchus leucocephalus'') is a Bird migration#Short-distance and altitudinal migration, nomadic wader of the stilt and avocet family, Recurvirostridae, native to Australia. It belongs to the monotypic genus ''Cladorhynchus''. It gets its name from the red-brown breast band found on breeding adults, though this is mottled or entirely absent in non-breeding adults and juveniles. Its remaining plumage is Piebald, pied and the eyes are dark brown. Nestling banded stilts have white down, unlike any other species of wader. Breeding is triggered by the filling of inland salt lakes by rainfall, creating large shallow lakes rich in tiny shrimp on which the birds feed. Banded stilts migrate to these lakes in large numbers and assemble in large breeding colonies. The female lays three to four brown- or black-splotched whitish Bird egg, eggs on a Bird nest#Scrape, scrape. If conditions are favourable, a second brood might be laid, though if the lakes dry up prematur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sharp-tailed Sandpiper
The sharp-tailed sandpiper (''Calidris acuminata'') is a small-medium migratory wader or shorebird, found mostly in Siberia during the summer breeding period (June to August) and Australia for wintering (September to March). Taxonomy The genus name ''calidris'' comes from the Ancient Greek ''kalidris'' or ''skalidris'', a term used by Aristotle for some grey-coloured waterside birds. The specific ''acuminata'' is from Latin ''acuminatus'', 'sharp, pointed'. It had previously been suggested that the sharp-tailed sandpiper should perhaps be placed into the genus ''Philomachus'' – as ''P. acuminatus'' – which contains the ruff, however this proposed change has yet to receive widespread acceptance. Description A small-medium wader, the portly sandpiper has a pot belly, flat back and somewhat drawn-out rear end. It has a mottled chestnut-brown upper body with sharp-looking feathers with a dark centre, a chestnut cap on its head and a brown stripe through each eye. Its bil ...

Red-necked Stint
The red-necked stint (''Calidris ruficollis'') is a small migratory wader. The genus name is from Ancient Greek ''kalidris'' or ''skalidris'', a term used by Aristotle for some grey-coloured waterside birds. The specific ''ruficollis'' is from Latin ''rufus'', "red" and ''collum'', "neck". Description These birds are among the smallest of waders, very similar to the little stint, ''Calidris minuta'', with which they were once considered conspecific. The red-necked stint's small size, fine dark bill, dark legs and quicker movements distinguish this species from all waders except the other dark-legged stints. It measures in length, in wingspan and in body mass. It can be distinguished from the western sandpiper and the semipalmated sandpiper in all plumages by its combination of a fine bill tip, unwebbed toes, and longer primary projection. The breeding adult has an unstreaked orange breast, bordered with dark markings below, and a white V on its back. In winter plumage identif ...

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 Endemism, 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 ...
