Ribble And Alt Estuaries
The Ribble and Alt Estuaries lie on the Irish Sea coast of the ceremonial counties of Lancashire and Merseyside in the traditional county of Lancashire in north-west England, and form the boundaries of a number of conservation schemes. Protected area A large number of different species of waders and wildfowl, listed below, use the estuaries as feeding and over-wintering areas. This wide variety of bird species has led to the estuaries being officially designated as a Special Protection Area and as a Ramsar site. The Ribble Estuary has been designated a Site of Special Scientific Interest since 1966 and is now covered by Natural England's Ribble Estuary National Nature Reserve. The site The Ribble Marshes National Nature Reserve is in extent and it is located in the middle of the SSSI which extends to . There are extensive areas of intertidal sand and silt flats, and expanses of saltmarsh. The mudflats have a large invertebrate fauna on which the waders and waterbirds feed. Th ...

Hectare
The hectare (; SI symbol: ha) is a non-SI metric unit of area equal to a square with 100-metre sides (1 hm2), or 10,000 m2, and is primarily used in the measurement of land. There are 100 hectares in one square kilometre. An acre is about and one hectare contains about . In 1795, when the metric system was introduced, the ''are'' was defined as 100 square metres, or one square decametre, and the hectare ("hecto-" + "are") was thus 100 ''ares'' or km2 (10,000 square metres). When the metric system was further rationalised in 1960, resulting in the International System of Units (), the ''are'' was not included as a recognised unit. The hectare, however, remains as a non-SI unit accepted for use with the SI and whose use is "expected to continue indefinitely". Though the dekare/decare daa (1,000 m2) and are (100 m2) are not officially "accepted for use", they are still used in some contexts. Description The hectare (), although not a unit of SI, i ...

Lesser Black-backed Gull
The lesser black-backed gull (''Larus fuscus'') is a large gull that breeds on the Atlantic coasts of Europe. It is migratory, wintering from the British Isles south to West Africa. It has increased dramatically in North America, most common along the east coast. Formerly just a winter visitor, many birds are now spotted year-round. Some winters they occur in large numbers. Even on the west coast, this species has become an annual winter visitor in California with birds reported around most of the state each winter. They've even been seen in numbers at the Salton Sea. Taxonomy The lesser black-backed gull was one of the many species originally described by Carl Linnaeus in his 1758 10th edition of ''Systema Naturae'', and it still bears its original name ''Larus fuscus''. The scientific name is from Latin. ''Larus'' appears to have referred to a gull or other large seabird, and ''fuscus'' meant black or brown. Subspecies The five recognized subspecies are: *''L. f. graellsii'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northern Pintail
The pintail or northern pintail (''Anas acuta'') is a duck species with wide geographic distribution that breeds in the northern areas of Europe and across the Palearctic and North America. It is migratory and winters south of its breeding range to the equator. Unusually for a bird with such a large range, it has no geographical subspecies if the possibly conspecific duck Eaton's pintail is considered to be a separate species. This is a large duck, and the male's long central tail feathers give rise to the species' English and scientific names. Both sexes have blue-grey bills and grey legs and feet. The drake is more striking, having a thin white stripe running from the back of its chocolate-coloured head down its neck to its mostly white undercarriage. The drake also has attractive grey, brown, and black patterning on its back and sides. The hen's plumage is more subtle and subdued, with drab brown feathers similar to those of other female dabbling ducks. Hens make a coarse ...

Pink-footed Goose
The pink-footed goose (''Anser brachyrhynchus'') is a goose which breeds in eastern Greenland, Iceland and Svalbard. It is migratory, wintering in northwest Europe, especially Ireland, Great Britain, the Netherlands, and western Denmark. The name is often abbreviated in colloquial usage to "pinkfoot" (plural "pinkfeet"). ''Anser'' is the Latin for "goose", and ''brachyrhynchus'' comes from the ancient Greek ''brachus'' "short" and ''rhunchos'' "bill". It is a medium-sized goose, long, the wingspan , and weighing . It has a short bill, bright pink in the middle with a black base and tip, and pink feet. The body is mid-grey-brown, the head and neck a richer, darker brown, the rump and vent white, and the tail grey with a broad white tip. The upper wing-coverts are of a somewhat similar pale bluish-grey as in the greylag goose, and the flight feathers blackish-grey. The species is most closely related to the bean goose ''Anser fabalis'' (having even been treated as a subspecies of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eurasian Oystercatcher
The Eurasian oystercatcher (''Haematopus ostralegus'') also known as the common pied oystercatcher, or palaearctic oystercatcher, or (in Europe) just oystercatcher, is a wader in the oystercatcher bird family Haematopodidae. It is the most widespread of the oystercatchers, with three races breeding in western Europe, central Eurosiberia, Kamchatka, China, and the western coast of Korea. No other oystercatcher occurs within this area. The extinct Canary Islands oystercatcher (''Haematopus meadewaldoi''), formerly considered a distinct species, may have actually been an isolated subspecies or distinct population of the Eurasian oystercatcher. This oystercatcher is the national bird of the Faroe Islands. Taxonomy The Eurasian oystercatcher was listed by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his '' Systema Naturae'' under the binomial name ''Haemotopus ostralegus''. The genus name ''Haematopus'' combines the Ancient Greek ''haima'' αἳμα meani ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Red Knot
The red knot or just knot (''Calidris canutus'') is a medium-sized shorebird which breeds in tundra and the Arctic Cordillera in the far north of Canada, Europe, and Russia. It is a large member of the ''Calidris'' sandpipers, second only to the great knot. Six subspecies are recognised. Their diet varies according to season; arthropods and larvae are the preferred food items at the breeding grounds, while various hard-shelled molluscs are consumed at other feeding sites at other times. North American breeders migrate to coastal areas in Europe and South America, while the Eurasian populations winter in Africa, Papua New Guinea, Australia, and New Zealand. This species forms enormous flocks when not breeding. Taxonomy, systematics, and evolution The red knot was first described by Carl Linnaeus in his landmark 1758 10th edition of ''Systema Naturae'' as ''Tringa canutus''. One theory is that it gets its name and species epithet from King Cnut; the name would refer to the kn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grey Plover
The grey plover or black-bellied plover (''Pluvialis squatarola'') is a large plover breeding in Arctic regions. It is a long-distance migrant, with a nearly worldwide coastal distribution when not breeding. Taxonomy The grey plover was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his ''Systema Naturae'' under the binomial name ''Tringa squatarola''. It is now placed with three other plovers in the genus ''Pluvialis'' that was introduced by the French onithologist Mathurin Jacques Brisson in 1760. The genus name is Latin and means relating to rain, from ''pluvia'', "rain". It was believed that they flocked when rain was imminent. The species name ''squatarola'' is a Latinised version of ''Sgatarola'', a Venetian name for some kind of plover. The English common name used for this species differs in different parts of the world. It is generally known as "grey plover" in the Old World and "black-bellied plover" in the New World. Th ...

European Golden Plover
The European golden plover (''Pluvialis apricaria''), also known as the European golden-plover, Eurasian golden plover, or just the golden plover within Europe, is a largish plover. This species is similar to two other golden plovers: the American golden plover, ''Pluvialis dominica'', and Pacific golden plover, ''Pluvialis fulva'', which are both smaller, slimmer and relatively longer-legged than European golden plover, and both have grey rather than white axillary feathers (only properly visible in flight). Taxonomy The European golden plover was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his ''Systema Naturae''. He placed it with the other plovers in the genus ''Charadrius'' and coined the binomial name ''Charadrius apricarius''. The species is now placed in the genus ''Pluvialis'' that was introduced in 1760 by the French zoologist Mathurin Jacques Brisson. The genus name is Latin and means "relating to rain", from ''pluvia'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dunlin
The dunlin (''Calidris alpina'') is a small wader, formerly sometimes separated with the other "stints" in the genus ''Erolia''. The English name is a dialect form of "dunling", first recorded in 1531–1532. It derives from ''dun'', "dull brown", with the suffix ''-ling'', meaning a person or thing with the given quality. It is a circumpolar breeder in Arctic or subarctic regions. Birds that breed in northern Europe and Asia are long-distance migrants, wintering south to Africa, southeast Asia and the Middle East. Birds that breed in Alaska and the Canadian Arctic migrate short distances to the Pacific and Atlantic coasts of North America, although those nesting in northern Alaska overwinter in Asia. Many dunlins winter along the Iberian south coast. Taxonomy The dunlin was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his ''Systema Naturae'' under the binomial name ''Tringa alpina''. Linnaeus specified the location as Lapland. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tundra 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. Description ''C. columbianus'' is the smallest of the Holarctic swans, at in length, in wingspan and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Black-tailed Godwit
The black-tailed godwit (''Limosa limosa'') is a large, long-legged, long-billed shorebird first described by Carl Linnaeus in 1758. It is a member of the godwit genus, ''Limosa''. There are four subspecies, all with orange head, neck and chest in breeding plumage and dull grey-brown winter coloration, and distinctive black and white wingbar at all times. Its breeding range stretches from Iceland through Europe and areas of central Asia. Black-tailed godwits spend (the northern hemisphere) winter in areas as diverse as the Indian subcontinent, Australia, New Zealand, western Europe and west Africa. The species breeds in fens, lake edges, damp meadows, moorlands and bogs and uses estuaries, swamps and floods in (the northern hemisphere) winter; it is more likely to be found inland and on freshwater than the similar bar-tailed godwit. The world population is estimated to be 634,000 to 805,000 birds and is classified as Near Threatened. The black-tailed godwit is the national bird ...

Bar-tailed Godwit
The bar-tailed godwit (''Limosa lapponica'') is a large and strongly migratory wader in the family Scolopacidae, which feeds on bristle-worms and shellfish on coastal mudflats and estuaries. It has distinctive red breeding plumage, long legs, and a long upturned bill. Bar-tailed godwits breed on Arctic coasts and tundra from Scandinavia to Alaska, and overwinter on coasts in temperate and tropical regions of Australia and New Zealand. The migration of the subspecies ''Limosa lapponica baueri'' across the Pacific Ocean from Alaska to New Zealand is the longest known non-stop flight of any bird, and also the longest journey without pausing to feed by any animal. The round-trip migration for this subspecies is over . Taxonomy The bar-tailed godwit was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his '' Systema Naturae'' under the binomial name ''Scolopax limosa''. It is now placed with three other godwits in the genus ''Limosa'' that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
