Hayle Estuary And Carrack Gladden SSSI
The Hayle Estuary and Carrack Gladden SSSI is a Site of Special Scientific Interest, noted for its biological interest, in west Cornwall, England, UK. It consists of three distinct parts, each of which is covered in a separate article: the Hayle Estuary, the sand-dune system of Porth Kidney Sands and the coastal headland at Carrack Gladden. Geography Hayle Estuary and Carrack Gladden SSSI is on the southern shore of St Ives Bay and to the west of the town of Hayle. The estuary of the River Hayle is the most south-westerly in Britain and adjacent to important bird migration routes which cross the Land's End peninsula. Part of the estuary, at Ryan's Field and Carnsew Pool, is owned by the Royal Society for the Protection of Birds (RSPB). Two long distant footpaths transverse or are close to the boundary of the SSSI. The South West Coast Path follows the coast from Carrack Gladden to North Quay, Hayle, while St Michael’s Way also follows the coast at Carrack Gladden as far as ...

Site Of Special Scientific Interest
A Site of Special Scientific Interest (SSSI) in Great Britain or an Area of Special Scientific Interest (ASSI) in the Isle of Man and Northern Ireland is a conservation designation denoting a protected area in the United Kingdom and Isle of Man. SSSI/ASSIs are the basic building block of site-based nature conservation legislation and most other legal nature/geological conservation designations in the United Kingdom are based upon them, including national nature reserves, Ramsar sites, Special Protection Areas, and Special Areas of Conservation. The acronym "SSSI" is often pronounced "triple-S I". Selection and conservation Sites notified for their biological interest are known as Biological SSSIs (or ASSIs), and those notified for geological or physiographic interest are Geological SSSIs (or ASSIs). Sites may be divided into management units, with some areas including units that are noted for both biological and geological interest. Biological Biological SSSI/ASSIs may ...

Eurasian Wigeon
The Eurasian wigeon or European wigeon (''Mareca penelope''), also known as the widgeon or the wigeon, is one of three species of wigeon in the dabbling duck genus ''Mareca''. It is common and widespread within its Palearctic range. Taxonomy The Eurasian wigeon was described by Carl Linnaeus in his landmark 1758 10th edition of ''Systema Naturae'' under the binomial name ''Anas penelope''. ''Anas'' is the Latin word for "duck", and ''penelope'' refers to a duck that was supposed to have rescued Penelope when she was thrown into the sea. Her name derives from Ancient Greek πήνη ''pene'', "braid" and ὤψ ''ops'' "appearance", from the ruse she used to deter suitors while her husband Ulysses was absent. Description This dabbling duck is long with a wingspan, and a weight of . The breeding male has grey flanks and back, with a black rear end, a dark green speculum and a brilliant white patch on upper wings, obvious in flight or at rest. It has a pink breast, white belly, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adit
An adit (from Latin ''aditus'', entrance) is an entrance to an underground mine which is horizontal or nearly horizontal, by which the mine can be entered, drained of water, ventilated, and minerals extracted at the lowest convenient level. Adits are also used to explore for mineral veins. Construction Adits are driven into the side of a hill or mountain, and are often used when an ore body is located inside the mountain but above the adjacent valley floor or coastal plain. In cases where the mineral vein outcrops at the surface, the adit may follow the lode or vein until it is worked out, in which case the adit is rarely straight. The use of adits for the extraction of ore is generally called drift mining. Adits can only be driven into a mine where the local topography permits. There will be no opportunity to drive an adit to a mine situated on a large flat plain, for instance. Also if the ground is weak, the cost of shoring up a long adit may outweigh its possible advantage ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ochre
Ochre ( ; , ), or ocher in American English, is a natural clay earth pigment, a mixture of ferric oxide and varying amounts of clay and sand. It ranges in colour from yellow to deep orange or brown. It is also the name of the colours produced by this pigment, especially a light brownish-yellow. A variant of ochre containing a large amount of hematite, or dehydrated iron oxide, has a reddish tint known as "red ochre" (or, in some dialects, ruddle). The word ochre also describes clays coloured with iron oxide derived during the extraction of tin and copper. Earth pigments Ochre is a family of earth pigments, which includes yellow ochre, red ochre, purple ochre, sienna, and umber. The major ingredient of all the ochres is iron(III) oxide-hydroxide, known as limonite, which gives them a yellow colour. * Yellow ochre, , is a hydrated iron hydroxide (limonite) also called gold ochre. * Red ochre, , takes its reddish colour from the mineral hematite, which is an anhydrous iron ...

Long-billed Dowitcher
The long-billed dowitcher (''Limnodromus scolopaceus'') is a medium-sized shorebird with a relatively long bill belonging to the sandpiper family, Scolopacidae. In breeding plumage, adults are characterized by a beautiful rufous head and underparts with a darker mottled back and a large white upper rump only seen in flight. They feed in various freshwater habitats with their bill underwater in a "sewing machine" motion and are known to have an exciting mating display where males chase females in flight. The genus, ''Limnodromus'' is Ancient Greek from ''limne'', "marsh" and ''dromos'', "racer". The specific ''scolopaceus'' is New Latin for "snipe-like", from Latin ''scolopax, scolopacis'', a snipe or woodcock. The English name is from Iroquois and was first recorded in 1841. The Long-billed dowitcher is nearly identical in appearance to the Short-billed dowitcher and was only recognized as a separate species in 1950 by Pitelka. Between the two, the best distinguishing field mar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
