Lemsford Springs
Lemsford Springs is a 4 hectare nature reserve in Lemsford, Hertfordshire, England. It is managed by the Herts and Middlesex Wildlife Trust, which purchased the site in 1970. Notable for its lagoons, the site is in the Lea valley and its other habitats are meadow, hedgerows, marsh and willow woodland. Before becoming a nature reserve, the site was used as a watercress bed. Its lagoons are fed by springs, so they never freeze over and provide an important habitat for birds in cold winters. There are two bird hides, and birds which can be seen include water rails, snipe and green sandpipers. Green sandpipers are migratory; a colour ringing project has revealed information about the travels of the Lemsford population including their breeding sites in Scandinavia.Smith K W (2002) Green sandpiper in The Migration Atlas: movements of the birds of Britain and Ireland.

Hertfordshire
Hertfordshire ( or ; often abbreviated Herts) is one of the home counties in southern England. It borders Bedfordshire and Cambridgeshire to the north, Essex to the east, Greater London to the south, and Buckinghamshire to the west. For government statistical purposes, it forms part of the East of England region. Hertfordshire covers . It derives its name – via the name of the county town of Hertford – from a hart (stag) and a ford, as represented on the county's coat of arms and on the flag. Hertfordshire County Council is based in Hertford, once the main market town and the current county town. The largest settlement is Watford. Since 1903 Letchworth has served as the prototype garden city; Stevenage became the first town to expand under post-war Britain's New Towns Act of 1946. In 2013 Hertfordshire had a population of about 1,140,700, with Hemel Hempstead, Stevenage, Watford and St Albans (the county's only ''city'') each having between 50,000 and 100,000 r ...

Herts And Middlesex Wildlife Trust
Herts and Middlesex Wildlife Trust manages over 40 nature reserves covering nearly north of London, in Hertfordshire and the historic county of Middlesex, part of which is divided between the London boroughs of Barnet, Enfield, Harrow and Hillingdon. It has over 21,000 members, and is one of 46 Wildlife Trusts across the UK. It is a Registered Charity, with its Registered Office in St Albans, and had an income in the year to 31 March 2014 of over £1.5 million. The trust's activities include managing nature reserves, advising landowners on how to manage their land for wildlife, commenting on planning applications, advising planning authorities and campaigning to protect wildlife. The trust also encourages people to be active volunteers helping to maintain nature reserves. The first preparatory meeting of what was to become the trust was held on 16 November 1963, and the Hertfordshire & Middlesex Trust for Nature Conservation was incorporated on 9 October 1964.

River Lea
The River Lea ( ) is in South East England. It originates in Bedfordshire, in the Chiltern Hills, and flows southeast through Hertfordshire, along the Essex border and into Greater London, to meet the River Thames at Bow Creek. It is one of the largest rivers in London and the easternmost major tributary of the Thames. The river's significance as a major east–west barrier and boundary has tended to obscure its importance as north–south trade route. Below Hertford the river has since medieval times had alterations made to make it more navigable for boats between the Thames and eastern Hertfordshire and Essex, known as the Lee Navigation. This stimulated much industry along its banks. The navigable River Stort, the main tributary, joins it at Hoddesdon. While the lower Lea remains somewhat polluted, its upper stretch and tributaries, classified as chalk streams, are a major source of drinking water for London. An artificial waterway known as the New River, opened in 1613, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Watercress
Watercress or yellowcress (''Nasturtium officinale'') is a species of aquatic flowering plant in the cabbage family Brassicaceae. Watercress is a rapidly growing perennial plant native to Europe and Asia. It is one of the oldest known leaf vegetables consumed by humans. Watercress and many of its relatives, such as garden cress, mustard, radish, and wasabi, are noteworthy for their piquant flavors. The hollow stems of watercress float in water. The leaf structure is pinnately compound. Small, white, and green inflorescences are produced in clusters and are frequently visited by insects, especially hoverflies, such as ''Eristalis'' flies. Taxonomy Watercress is listed in some sources as belonging to the genus ''Rorippa'', although molecular evidence shows those aquatic species with hollow stems are more closely related to ''Cardamine'' than ''Rorippa''. Despite the Latin name, watercress is not particularly closely related to the flowers popularly known as nasturtiums (''Trop ...

Bird Hide
A bird hide (blind or bird blind in North America) is a shelter, often camouflaged, that is used to observe wildlife, especially birds, at close quarters. Although hides or hunting blinds were once built chiefly as hunting aids, they are now commonly found in parks and wetlands for the use of birdwatchers, ornithologists and other observers who do not want to disturb wildlife as it is being observed. A typical bird hide resembles a garden shed, with small openings, shutters, or windows built into at least one side to enable observation. However, because birds do not recognize humans as predatory threats unless the human is standing in the open, a bird blind can be little more than a large shed open on one side in which birders stand, and motor vehicles are effective blinds even with the windows open. Variants Types of bird hide include: * tower hides, which have multiple stories and allow observations over large areas. * bird blinds, which are screens similar to one wall of a ty ...

Water Rail
The water rail (''Rallus aquaticus'') is a bird of the rail family which breeds in well-vegetated wetlands across Europe, Asia and North Africa. Northern and eastern populations are migratory, but this species is a permanent resident in the warmer parts of its breeding range. The adult is long, and, like other rails, has a body that is flattened laterally, allowing it easier passage through the reed beds it inhabits. It has mainly brown upperparts and blue-grey underparts, black barring on the flanks, long toes, a short tail and a long reddish bill. Immature birds are generally similar in appearance to the adults, but the blue-grey in the plumage is replaced by buff. The downy chicks are black, as with all rails. The former subspecies ''R. indicus'', has distinctive markings and a call that is very different from the pig-like squeal of the western races, and is now usually split as a separate species, the brown-cheeked rail. The water rail breeds in reed beds and other mar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gallinago Gallinago
The common snipe (''Gallinago gallinago'') is a small, stocky wader native to the Old World. The breeding habitats are marshes, bogs, tundra and wet meadows throughout the Palearctic. In the north, the distribution limit extends from Iceland over the north of the British Isles and northern Fennoscandia, where it occurs at around 70°N, as well as through European Russia and Siberia. Here it is mostly on the northern edge of the Taiga zone at 71°N, but reaches 74°N on the east coast of the Taymyr Peninsula. In the east it extends to Anadyr, Kamchatka, Bering Island and the Kuril Islands, The southern boundary of the distribution area in Europe runs through northern Portugal, central France, northern Italy, Bulgaria, and Ukraine, with populations in the west being only very scattered. In Asia, the distribution extends south to northern Turkestan, locally to Afghanistan and the Middle East, through the Altai and further to Manchuria and Ussuri. It is migratory, with European b ...

Green Sandpiper
The green sandpiper (''Tringa ochropus'') is a small wader (shorebird) of the Old World. The green sandpiper represents an ancient lineage of the genus ''Tringa''; its only close living relative is the solitary sandpiper (''T. solitaria''). They both have brown wings with little light dots and a delicate but contrasting neck and chest pattern. In addition, both species nest in trees, unlike most other scolopacids. Given its basal position in ''Tringa'', it is fairly unsurprising that suspected cases of hybridisation between this species and the common sandpiper (''A. hypoleucos'') of the sister genus ''Actitis'' have been reported. Taxonomy The green sandpiper was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his ''Systema Naturae'' under the current binomial name ''Tringa ochropus''. The genus name ''Tringa'' is the New Latin name given to the green sandpiper by Aldrovandus in 1599 based on Ancient Greek ''trungas'', a thrush ...

Bird Migration
Bird migration is the regular seasonal movement, often north and south along a flyway, between breeding and wintering grounds. Many species of bird migrate. Migration carries high costs in predation and mortality, including from hunting by humans, and is driven primarily by the availability of food. It occurs mainly in the northern hemisphere, where birds are funneled onto specific routes by natural barriers such as the Mediterranean Sea or the Caribbean Sea. Migration of species such as storks, turtle doves, and swallows was recorded as many as 3,000 years ago by Ancient Greek authors, including Homer and Aristotle, and in the Book of Job. More recently, Johannes Leche began recording dates of arrivals of spring migrants in Finland in 1749, and modern scientific studies have used techniques including bird ringing and satellite tracking to trace migrants. Threats to migratory birds have grown with habitat destruction, especially of stopover and wintering sites, as wel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bird Ringing
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming. Birds ...

Eurasian Water Shrew
The Eurasian water shrew (''Neomys fodiens''), known in the United Kingdom as the water shrew, is a relatively large shrew, up to long, with a tail up to three-quarters as long again. It has short, dark fur, often with a few white tufts, a white belly, and a few stiff hairs around the feet and tail. It lives close to fresh water, hunting aquatic prey in the water and nearby. Its fur traps bubbles of air in the water which greatly aids its buoyancy, but requires it to anchor itself to remain underwater for more than the briefest of dives. Like many shrews, the water shrew has venomous saliva, making it one of the few venomous mammals, although it is not able to puncture the skin of large animals, nor that of humans. Highly territorial, it lives a solitary life and is found throughout the northern part of Europe and Asia, from Britain to Korea. Description The Eurasian water shrew grows to a length of about long with a tail length of and weight of . The dense short fur on the h ...
