Valley Wetlands
Valley Wetlands ( cy, Gwlyptiroedd y Fali), formerly Valley Lakes, is a nature reserve in Anglesey, Wales belonging to the Royal Society for the Protection of Birds. It is an area of lakes and reedbeds to the south-east of Valley in Llanfair-yn-Neubwll community, adjacent to RAF Valley airfield. The western section of the reserve includes Llyn Penrhyn, Llyn Treflesg and part of Llyn Dinam. The eastern part includes Llyn Traffwll and wetlands along the Afon Crigyll. Much of the reserve is included within two Sites of Special Scientific Interest. Breeding birds include good numbers of sedge and reed warblers which have been joined in recent years by Cetti's warbler. Several species of duck breed including shoveler, gadwall and pochard. Outside the breeding season, duck numbers increase and bittern and marsh harrier are regularly seen. Several rare birds have been recorded such as whiskered tern, green-winged teal and ring-necked duck. The reserve is rich in wetland plants wi ...

Duck
Duck is the common name for numerous species of waterfowl in the family Anatidae. Ducks are generally smaller and shorter-necked than swans and geese, which are members of the same family. Divided among several subfamilies, they are a form taxon; they do not represent a monophyletic group (the group of all descendants of a single common ancestral species), since swans and geese are not considered ducks. Ducks are mostly aquatic birds, and may be found in both fresh water and sea water. Ducks are sometimes confused with several types of unrelated water birds with similar forms, such as loons or divers, grebes, gallinules and coots. Etymology The word ''duck'' comes from Old English 'diver', a derivative of the verb 'to duck, bend down low as if to get under something, or dive', because of the way many species in the dabbling duck group feed by upending; compare with Dutch and German 'to dive'. This word replaced Old English / 'duck', possibly to avoid conf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hairy Dragonfly
''Brachytron'' is a monotypic genus of European dragonfly of the family Aeshnidae containing the hairy dragonfly (''Brachytron pratense''), also known as the hairy hawker or spring hawker. Description The hairy dragonfly is named for its hairy thorax, distinguishing it from other hawkers. It has a long, narrow pterostigma The pterostigma (plural: pterostigmata) is a group of specialized cells in the outer wings of insects, which are often thickened or coloured, and thus stand out from other cells. It is particularly noticeable in dragonflies, but present also in ... (the coloured, sclerotized patch on the outer region of each wing). The antehumeral stripes are usually thin and green. The hairy dragonfly has coupled, oval-shaped markings on its abdomen, blue on males and yellow on females. It is smaller than other species in the genus Aeshna. It is the United Kingdom's smallest hawker.. Habitat The hairy dragonfly lives in ponds, lakes, fens, ditches, and canals rich in ve ...

Thelypteris Palustris
''Thelypteris palustris'', the marsh fern, or eastern marsh fern, is a species of fern native to eastern North America and across Eurasia. It prefers to grow in marshy situations in full sun. The species epithet ''palustris'' is Latin for "of the marsh" and indicates its common habitat. It is the only known host plant for ''Fagitana littera ''Fagitana littera'', the marsh fern moth, is a moth of the family Noctuidae.

Butomus Umbellatus
''Butomus umbellatus'' is a Eurasian plant species in the family Butomaceae. It is the only species in the family. Common names include flowering rush or grass rush. Introduced into North America as an ornamental plant it has now become a serious invasive weed in the Great Lakes area and in parts of the Pacific Northwest. In Israel, one of its native countries, it is an endangered species due to the habitat loss. It can also be found in Great Britain locally, for example at the Caldicot and Wentloog Levels The plant is a rhizomatous, hairless, perennial aquatic plant. Its name is derived from Greek ''bous'', meaning "cow", "ox" etc. and ''tome'', a cut (the verb 'temnein' meaning "to cut"), which refers to the plant's swordlike leaves. Description In contrast to what its English name suggests, it is not a true rush. It is native to Old World continents and grows on the margins of still and slowly moving water down to a depth of about 3 m. It has pink flowers. The plant has lin ...

Ring-necked Duck
The ring-necked duck (''Aythya collaris'') is a diving duck from North America commonly found in freshwater ponds and lakes. The scientific name is derived from Greek , an unidentified seabird mentioned by authors including Hesychius and Aristotle, and Latin ''collaris'', "of the neck" from ''collum'', "neck". Description Ring-necked ducks are small to medium-sized diving ducks with the following length, weight, and wingspan measurements: * Length: 15.3-18.1 in (39-46 cm) * Weight: 17.3-32.1 oz (490-910 g) * Wingspan: 24.4-24.8 in (62-63 cm) The adult male is similar in color pattern to the Eurasian tufted duck, its relative. Males are a little bit bigger than the female. It has two white rings surrounding its gray bill, a shiny black angular head, black back, white line on the wings, a white breast and yellow eyes. The adult female has a grayish brown angular head and body with a dark brown back, a dark bill with a more subtle light band than the male, grayish- ...

Green-winged Teal
The green-winged teal (''Anas carolinensis'') is a common and widespread duck that breeds in the northern areas of North America except on the Aleutian Islands. It was considered conspecific with the Eurasian teal (''A. crecca'') for some time, but has since been split into its own species. The American Ornithological Society continues to debate this determination, however nearly all other authorities consider it distinct based on behavioral, morphological, and molecular evidence. The scientific name is from Latin ''Anas'', "duck" and ''carolinensis'', "of Carolina". This dabbling duck is strongly migratory and winters far south of its breeding range. It is highly gregarious outside of the breeding season and will form large flocks. In flight, the fast, twisting flocks resemble waders. Taxonomy The green-winged teal was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's ''Systema Naturae''. He plac ...

Whiskered Tern
The whiskered tern (''Chlidonias hybrida'') is a tern in the family Laridae. The genus name is from Ancient Greek ''khelidonios'', "swallow-like", from ''khelidon'', " swallow". The specific ''hybridus'' is Latin for ''hybrid''; Peter Simon Pallas thought it might be a hybrid of white-winged black tern and common tern, writing "''Sterna fissipes 'Chlidonias leucopterus''et Hirundine 'Sterna hirundo''natam''”. This bird has a number of geographical races, differing mainly in size and minor plumage details. ''C. h. hybrida'' breeds in warmer parts of Europe and the Palearctic (northwestern Africa and central and southern Europe to southeastern Siberia, eastern China and south to Pakistan and northern India). The smaller-billed and darker ''C. h. delalandii'' is found in east and south Africa, and the paler ''C. h. javanicus'' from Java to Australia. The tropical forms are resident, but European and Asian birds winter south to Africa and the Indian Subcontinent. A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Western Marsh Harrier
The western marsh harrier (''Circus aeruginosus'') is a large harrier, a bird of prey from temperate and subtropical western Eurasia and adjacent Africa. It is also known as the Eurasian marsh harrier. Formerly, a number of relatives were included in ''C. aeruginosus'', which was then known as " marsh harrier". The related taxa are now generally considered to be separate species: the eastern marsh harrier (''C. spilonotus''), the Papuan harrier (''C. spilothorax'') of eastern Asia and the Wallacea, the swamp harrier (''C. approximans'') of Australasia and the Madagascar marsh harrier (''C. maillardi'') of the western Indian Ocean islands. The western marsh harrier is often divided into two subspecies, the widely migratory ''C. a. aeruginosus'' which is found across most of its range, and ''C. a. harterti'' which is resident all-year in north-west Africa. Taxonomy The western marsh harrier was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eurasian Bittern
The Eurasian bittern or great bittern (''Botaurus stellaris'') is a wading bird in the bittern subfamily (Botaurinae) of the heron family Ardeidae. There are two subspecies, the northern race (''B. s. stellaris'') breeding in parts of Europe and across the Palearctic, as well as on the northern coast of Africa, while the southern race (''B. s. capensis'') is endemic to parts of southern Africa. It is a secretive bird, seldom seen in the open as it prefers to skulk in reed beds and thick vegetation near water bodies. Its presence is apparent in the spring, when the booming call of the male during the breeding season can be heard. It feeds on fish, small mammals, fledgling birds, amphibians, crustaceans and insects. The nest is usually built among reeds at the edge of bodies of water. The female incubates the clutch of eggs and feeds the young chicks, which leave the nest when about two weeks old. She continues to care for them until they are fully fledged some six weeks later.
