Grazing Marsh
Grazing marsh is a British Isles term for flat, marshy grassland in polders. It consists of large grass fields separated by fresh or brackish ditches, and is often important for its wildlife. History Grazing marshes were created from medieval times by building sea walls (earth banks) across tidal mudflats and salt marsh to make polders (though the term "polder" is little used in Britain). Polders in Britain are mostly drained by gravity, rather than active pumping. The original tidal drainage channels were augmented by new ditches, and flap valves in the sea walls let water drain out at low tide and prevent the sea or tidal river from entering at high tide. Constructing polders in this way is called ''inning'' or ''reclaiming'' from the sea. Grazing marshes have been made in most lowland estuaries in Britain, often leaving only the river channel and the lowest part of the estuary tidal. In a few cases (such as Newtown Harbour on the Isle of Wight, and Pagham Harbour in West S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British Isles
The British Isles are an archipelago in the Atlantic Ocean, North Atlantic Ocean off the north-western coast of continental Europe, consisting of the islands of Great Britain, Ireland, the Isle of Man, the Inner Hebrides, Inner and Outer Hebrides, Outer Hebrides, the Northern Isles (Orkney and Shetland), and over six thousand smaller islands. They have a total area of and a combined population of almost 72 million, and include two sovereign states, the Republic of Ireland (which covers roughly five-sixths of Ireland), and the United Kingdom, United Kingdom of Great Britain and Northern Ireland. The Channel Islands, off the north coast of France, are normally taken to be part of the British Isles, even though geographically they do not form part of the archipelago. Under the UK Interpretation Act 1978, the Channel Islands are clarified as forming part of the British Islands, not to be confused with the British Isles. The oldest rocks are 2.7 billion years old and are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pagham Harbour
Pagham Harbour is a biological and geological Site of Special Scientific Interest on the western outskirts of Bognor Regis in West Sussex. It is a Geological Conservation Review site, a Nature Conservation Review site, a Ramsar site, a Special Protection Area and a Marine Conservation Zone. An area of is a RSPB Local Nature Reserve. Land owners of the harbour include the Royal Society for the Protection of Birds, the Crown Estate and the Church Commissioners. The harbour forms an area of saltmarsh and shallow lagoons. It is not an estuary, as no major streams enter the harbour with the only freshwater inflow a few small streams draining surrounding fields. History In earlier times Pagham Harbour was a working harbour with three ports. One port was situated at the western end, of the harbour near Sidlesham Mill, and was known as Wardur. The port of Charlton was at the entrance to the harbour and the third was on the Pagham side of the harbour and was known as the Port of Wyth ...

Snipe
A snipe is any of about 26 wading bird species in three genera in the family Scolopacidae. They are characterized by a very long, slender bill, eyes placed high on the head, and cryptic/ camouflaging plumage. ''Gallinago'' snipe have a nearly worldwide distribution, the '' Lymnocryptes'' snipe is restricted to Asia and Europe and the ''Coenocorypha'' snipe is found only in the outlying islands of New Zealand. The four species of painted snipe are not closely related to the typical snipe, and are placed in their own family, the Rostratulidae. Behaviour Snipe search for invertebrates in the mud with a " sewing-machine" action of their long bills. The sensitivity of the bill is caused by filaments belonging to the fifth pair of nerves, which run almost to the tip and open immediately under the soft cuticle in a series of cells; a similar adaptation is found in sandpipers; this adaptation gives this portion of the surface of the premaxillaries a honeycomb-like appearance: wi ...

Eurasian Curlew
The Eurasian curlew or common curlew (''Numenius arquata'') is a very large wader in the family Scolopacidae. It is one of the most widespread of the curlews, breeding across temperate Europe and Asia. In Europe, this species is often referred to just as the "curlew", and in Scotland known as the "whaup" in Scots. Taxonomy The Eurasian curlew was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his ''Systema Naturae'' under the binomial name ''Scolopax arquata''. It is now placed with eight other curlews in the genus '' Numenius'' that was introduced by the French ornithologist Mathurin Jacques Brisson in 1760. The genus name ''Numenius'' is from Ancient Greek νουμήνιος, ''noumēnios'', a bird mentioned by Hesychius. It is associated with the curlew because it appears to be derived from ''neos'', "new" and ''mene'' "moon", referring to the crescent-shaped bill. The species name ''arquata'' is the Medieval Latin name for this ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Common Redshank
The common redshank or simply redshank (''Tringa totanus'') is a Eurasian wader in the large family Scolopacidae. Taxonomy The common redshank was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his ''Systema Naturae'' under the binomial name ''Scolopax totanus''. It is now placed with twelve other species in the genus ''Tringa'' that Linnaeus had introduced in 1758. The genus name ''Tringa'' is the Neo-Latin name given to the green sandpiper by the Italian naturalist Ulisse Aldrovandi in 1603 based on Ancient Greek ''trungas'', a thrush-sized, white-rumped, tail-bobbing wading bird mentioned by Aristotle. The specific ''totanus'' is from , the Italian name for this bird. Six subspecies are recognised: * ''T. t. robusta'' ( Schiøler, 1919) – breeds in Iceland and the Faroe Islands; non-breeding around the British Isles and west Europe * ''T. t. totanus'' (Linnaeus, 1758) – breeds in west, north Europe to west Siberia; winter ...

Wader
245px, A flock of 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 smaller species found ...

Marsh Harrier
The marsh harriers are bird of prey, birds of prey of the harrier (bird), harrier subfamily. They are medium-sized Bird of prey, raptors and the largest and broadest-winged harriers. Most of them are associated with marshland and dense reedbeds. They are found almost worldwide, excluding only the Americas. Until recently two species were generally recognized: the marsh harrier (''Circus aeruginosus'') and the African marsh harrier (''C. ranivorus''). The marsh harrier is now usually split into several species, sometimes as many as six. These are the western marsh harrier (''C. aeruginosus''), eastern marsh harrier (''C. spilonotus''), Papuan harrier (''C. spilonotus spilothorax'' or ''C. spilothorax''), swamp harrier (''C. approximans''), Réunion harrier (''C. maillardi maillardi'' or ''C. maillardi'') and Madagascar marsh harrier (''C. maillardi macrosceles'' or ''C. macrosceles''). At the beginning of the 20th century, the marsh harrier was hunted to extinction in the United K ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peregrine Falcon
The peregrine falcon (''Falco peregrinus''), also known simply as the peregrine, is a Cosmopolitan distribution, cosmopolitan bird of prey (raptor) in the family (biology), family Falconidae renowned for its speed. A large, Corvus (genus), crow-sized falcon, it has a blue-grey back, barred white underparts, and a black head. As is typical for avivore, bird-eating (avivore) raptors, peregrine falcons are Sexual dimorphism, sexually dimorphic, with females being considerably larger than males. Historically, it has also been known as "black-cheeked falcon" in Australia, and "duck hawk" in North America. The breeding range includes land regions from the Arctic tundra to the tropics. It can be found nearly everywhere on Earth, except extreme polar regions, very high mountains, and most tropical rainforests; the only major ice-free landmass from which it is entirely absent is New Zealand. This makes it the world's most widespread Raptor (bird), raptor and one of the most widely found ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bewick's Swan
The tundra swan (''Cygnus columbianus'') is a small swan of the Holarctic. The two taxa within it are usually regarded as conspecific, but are also sometimes split into two species: Bewick's swan (''Cygnus bewickii'') of the Palaearctic and the whistling swan (''C. columbianus'') proper of the Nearctic. Birds from eastern Russia (roughly east of the Taymyr Peninsula) are sometimes separated as the subspecies ''C. c. jankowskii'', but this is not widely accepted as distinct, with most authors including them in ''C. c. bewickii''. Tundra swans are sometimes separated in the subgenus ''Olor'' together with the other Arctic swan species. Bewick's swan was named in 1830 by William Yarrell after the engraver Thomas Bewick, who specialised in illustrations of birds and animals. ''Cygnus'' is the Latin for "swan", and '' columbianus'' comes from the Columbia River, the type locality.

White-fronted Goose
The greater white-fronted goose (''Anser albifrons'') is a species of goose, closely related to the smaller lesser white-fronted goose (''A. erythropus''). The greater white-fronted goose is migratory, breeding in northern Canada, Alaska, Greenland and Russia, and winters farther south in North America, Europe and Asia. It is named for the patch of white feathers bordering the base of its bill: ''albifrons'' comes from the Latin "white" and "forehead". In the United Kingdom and Ireland, it has been known as the white-fronted goose; in North America it is known as the greater white-fronted goose (or "greater whitefront"), and this name is also increasingly adopted internationally. Even more distinctive are the salt-and-pepper markings on the breast of adult birds, which is why the goose is colloquially called the "specklebelly" in North America. Description Greater white-fronted geese are in length, have a wingspan, and weigh . They have bright orange legs and mouse-co ...

Brent Goose
The brant or brent goose (''Branta bernicla'') is a small goose of the genus ''Branta''. There are three subspecies, all of which winter along temperate-zone sea-coasts and breed on the high-Arctic tundra. The Brent oilfield was named after the species. Taxonomy The brant was formally described in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his ''Systema Naturae'' under the binomial name ''Anas bernicla''. Linnaeus specified the type locality as Europe but in 1761 restricted it to Sweden. The brant is now one of six species placed in the genus ''Branta'' that was introduced in 1769 by the Austrian naturalist Giovanni Antonio Scopoli. The genus name ''Branta'' is a Latinised form of Old Norse ''brandgás'', "burnt (black) goose". The specific epithet ''bernicla'' is Medieval Latin for barnacle. The brant and the similar barnacle goose were previously considered to be the same species and believed to be the same creature as the barnacle. That myth c ...

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 formally 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 said to have saved 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 away. 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, visible in flight or at rest. It has a pink breast, white belly, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
