Dampier Saltworks Important Bird Area
The Dampier Saltworks Important Bird Area is a 52 km2 saltern lying close to the town of Dampier, an industrial port in the Pilbara region of north-west Western Australia. The salt processing facility is operated by Dampier Salt Ltd, part of the Rio Tinto Group. Birds The solar evaporation ponds at Dampier have been identified by BirdLife International as an Important Bird Area (IBA). They regularly support over 1% of the world populations of the red-capped plover and red-necked stint and similarly support the Oriental plover and sharp-tailed sandpiper occasionally. The saltworks is also home to small numbers of the range-restricted dusky gerygone.

Charadrius Ruficapillus Breeding Plumage
'' Charadrius '' is a genus of plovers, a group of wading birds. The genus name ''Charadrius'' is a Late Latin word for a yellowish bird mentioned in the fourth-century Vulgate. They are found throughout the world. Many ''Charadrius'' species are characterised by breast bands or collars. These can be (in the adult) complete bands (ringed, semipalmated, little ringed, long-billed), double or triple bands (killdeer, three-banded, Forbes', two-banded, double-banded) or partial collars (Kentish, piping, snowy, Malaysian, Javan, red-capped, puna). They have relatively short bills and feed mainly on insects, worms or other invertebrates, depending on habitat, which are obtained by a run-and-pause technique, rather than the steady probing of some other wader groups. They hunt by sight, rather than by feel as do longer-billed waders like snipe. Species of the genus ''Aegialites'' (or ''Aegialitis'') are now subsumed within ''Charadrius''. Taxonomy The genus ''Charadrius'' was introduc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Important Bird Area
An Important Bird and Biodiversity Area (IBA) is an area identified using an internationally agreed set of criteria as being globally important for the conservation of bird populations. IBA was developed and sites are identified by BirdLife International. There are over 13,000 IBAs worldwide. These sites are small enough to be entirely conserved and differ in their character, habitat or ornithological importance from the surrounding habitat. In the United States the Program is administered by the National Audubon Society. Often IBAs form part of a country's existing protected area network, and so are protected under national legislation. Legal recognition and protection of IBAs that are not within existing protected areas varies within different countries. Some countries have a National IBA Conservation Strategy, whereas in others protection is completely lacking.

Port Hedland Saltworks Important Bird Area
The Port Hedland Saltworks Important Bird Area is a 103 km2 tract of originally intertidal land, now containing a saltern, lying about 20 km east of the port of Port Hedland on the coast of the Pilbara region of north-west Western Australia. The salt processing facility is operated by Dampier Salt Ltd, part of the Rio Tinto Group. Description The Important Bird Area (IBA) comprises a system of evaporation ponds, the intake zone where seawater enters, and the adjacent intertidal mudflats. The system includes levee banks and scattered mangroves. During low tides, waterbirds forage on the mudflats and along nearby creeks. During high tides, they move to the saltworks to continue feeding or to roost.BirdLife International. (2011). Important Bird Areas factsheet: Port Hedland Saltworks.

Sharp-tailed Sandpiper
The sharp-tailed sandpiper (''Calidris acuminata'') (but see below) is a small wader. Taxonomy A review of data has indicated that this bird should perhaps better be placed into the genus ''Philomachus'' – as ''P. acuminatus'' – which now contains only the ruff but if the sharp-tailed sandpiper is merged into it would need to accommodate the broad-billed sandpiper. While the latter is a peculiar calidrid, the sharp-tailed sandpiper is much more similar to other ''Calidris''/''Erolia'' species such as the pectoral sandpiper. On the one hand, its larger size and long-legged stance, and the breast pattern which gradually fades away on the belly as in the ruff instead of having a fairly sharp border as in the ''Calidris''/''Erolia'' stints indicate that placement in ''Philomachus'' may be correct. Still, it is just as possible that – given the fairly common instances of hybridization in calidrines – mitochondrial DNA data has given a false picture of this species' true af ...

Oriental Plover
The oriental plover (''Charadrius veredus''), also known as the oriental dotterel, is a medium-sized plover closely related to the Caspian plover. It breeds in parts of Mongolia and China, migrating southwards each year to spend its non-breeding season in Indonesia, New Guinea and northern Australia. Description Adult male in breeding plumage: white face, throat and fore-crown; grey-brown hind-crown, hind-neck and back; belly white, demarcated with narrow black band and then broad chestnut breast band merging into white throat. Female, juvenile and non-breeding male: generally grey-brown upperparts and white belly; pale face with white streak above eye. Measurements: length 21–25 cm; wingspan 46–53 cm; weight 95 g. Among the red-breasted Charadrius plovers, this bird is relatively large, long-legged and long-winged. Distribution and habitat Breeds in Mongolia, eastern Russia and Manchuria; migrates through eastern China and South-East Asia to Indonesia and n ...

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 identifi ...

Red-capped Plover
The red-capped plover (''Charadrius 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 loreal stripe. The upperwing of ''Charadrius ruficapillus'' shows dark brown 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 margins. Distribution and habitat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Saltern
A saltern is an area or installation for making salt. Salterns include modern salt-making works (saltworks), as well as hypersaline waters that usually contain high concentrations of halophilic microorganisms, primarily haloarchaea but also other halophiles including algae and bacteria. Salterns usually begin with seawater as the initial source of brine but may also use natural saltwater springs and streams. The water is evaporated, usually over a series of ponds, to the point where sodium chloride and other salts precipitate out of the saturated brine, allowing pure salts to be harvested. Where complete evaporation in this fashion was not routinely achievable due to weather, salt was produced from the concentrated brine by boiling the brine. Background Earliest examples of pans used in the solution mining of salt date back to prehistoric times and the pans were made of ceramics known as briquetage. Later examples were made from lead and then iron. The change from lead to iron ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salt Evaporation Pond
A salt evaporation pond is a shallow artificial salt pan designed to extract salts from sea water or other brines. The Salt pans are shallow and large of size because it will be easier for sunlight to travel and reach the sea water. Natural salt pans are geological formations that are also created by water evaporating and leaving behind salts. Some salt evaporation ponds are only slightly modified from their natural version, such as the ponds on Great Inagua in the Bahamas, or the ponds in Jasiira, a few kilometres south of Mogadishu, where seawater is trapped and left to evaporate in the sun. The seawater or brine is fed into large ponds and water is drawn out through natural evaporation which allows the salt to be subsequently harvested. The ponds also provide a productive resting and feeding ground for many species of waterbirds, which may include endangered species. The ponds are commonly separated by levees. Salt evaporation ponds may also be called salterns, salt works or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
