Summer Leys
Summer Leys is a local nature reserve at Wollaston in the Upper Nene Valley, in Northamptonshire, England. It is owned by the Wildlife Trust for Bedfordshire, Cambridgeshire and Northamptonshire. Topography The reserve, created from former gravel pits, covers just under and is primarily wetland, with some grassland and woodland habitats, and hedges. The grassland is managed by the use of grazing cattle and rare-breed sheep, supported by a grant from the SITA Trust. The northern perimeter of the reserve is delineated by the trackbed of the former Northampton and Peterborough Railway, closed in 1972. The reserve has four bird hides and a viewing screen. One of the hides overlooks a feeding station. A car park is available off Hardwater Road. Designation The reserve and neighbouring gravel pits, collectively the Upper Nene Valley Gravel Pits, are designated as a Site of Special Scientific Interest (SSSI), a Special Protection Area (SPA) and a Ramsar wetland of intern ...

Quarry
A quarry is a type of open-pit mine in which dimension stone, rock, construction aggregate, riprap, sand, gravel, or slate is excavated from the ground. The operation of quarries is regulated in some jurisdictions to reduce their environmental impact. The word ''quarry'' can also include the underground quarrying for stone, such as Bath stone. Types of rock Types of rock extracted from quarries include: *Chalk *China clay *Cinder *Clay *Coal * Construction aggregate (sand and gravel) * Coquina * Diabase *Gabbro *Granite * Gritstone *Gypsum *Limestone *Marble *Ores *Phosphate rock *Quartz *Sandstone * Slate *Travertine Stone quarry Stone quarry is an outdated term for mining construction rocks (limestone, marble, granite, sandstone, etc.). There are open types (called quarries, or open-pit mines) and closed types ( mines and caves). For thousands of years, only hand tools had been used in quarries. In the 18th century, the use of drilling and blasting operatio ... [...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 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 ''Aeshna'', or the mosaic darners, is a genus of dragonflies from the family Aeshnidae. Species within this genus are generally known as "hawkers" (Old World) or "darners" (New World). Description These are relatively large dragonflies. T ....

Eurasian Otter
The Eurasian otter (''Lutra lutra''), also known as the European otter, Eurasian river otter, common otter, and Old World otter, is a semiaquatic mammal native to Eurasia. The most widely distributed member of the otter subfamily (Lutrinae) of the weasel family (Mustelidae), it is found in the waterways and coasts of Europe, many parts of Asia, and parts of northern Africa. The Eurasian otter has a diet mainly of fish, and is strongly territorial. It is endangered in some parts of its range, but is recovering in others. Description The Eurasian otter is a typical species of the otter subfamily. Brown above and cream below, these long, slender creatures are well-equipped for their aquatic habits. Their bones show osteosclerosis, increasing their density to reduce buoyancy. This otter differs from the North American river otter by its shorter neck, broader visage, the greater space between the ears and its longer tail. However, the Eurasian otter is the only otter in much of its ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Tufted Duck
The tufted duck or tufted pochard (''Aythya fuligula'') is a small diving duck with a population of close to one million birds, found in northern Eurasia. The scientific name is derived from Ancient Greek '' aithuia'', an unidentified seabird mentioned by authors including Hesychius and Aristotle, and ''Latin'' ''fuligo'' "soot" and ''gula'' "throat". Description The adult male is all black except for white flanks and a blue-grey bill with gold-yellow eyes, along with a thin crest on the back of its head. It has an obvious head tuft that gives the species its name. The adult female is brown with paler flanks, and is more easily confused with other diving ducks. In particular, some have white around the bill base which resembles the scaup species, although the white is never as extensive as in those ducks. The females' call is a harsh, growling "karr", mostly given in flight. The males are mostly silent but they make whistles during courtship based on a simple "wit-oo". The onl ...

Eurasian Teal
The Eurasian teal (''Anas crecca''), common teal, or Eurasian green-winged teal is a common and widespread duck that breeds in temperate Eurosiberia and migrates south in winter. The Eurasian teal is often called simply the teal due to being the only one of these small dabbling ducks in much of its range. The bird gives its name to the blue-green colour teal. It is a highly gregarious duck outside the breeding season and can form large flocks. It is commonly found in sheltered wetlands and feeds on seeds and aquatic invertebrates. The North American green-winged teal (''A. carolinensis'') was formerly (and sometimes is still) considered a subspecies of ''A. crecca''. Taxonomy The Eurasian teal belongs to the "true" teals, a group of small ''Anas'' dabbling ducks closely related to the mallard (''A. platyrhynchos'') and its relatives; that latter group in fact seems to have evolved from a true teal. It forms a superspecies with the green-winged teal and the speckled ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northern Shoveller
The northern shoveler (; ''Spatula clypeata''), known simply in Britain as the shoveler, is a common and widespread duck. It breeds in northern areas of Europe and across the Palearctic and across most of North America, wintering in southern Europe, the Indian subcontinent, Southeast Asia, Central, the Caribbean, and northern South America. It is a rare vagrant to Australia. In North America, it breeds along the southern edge of Hudson Bay and west of this body of water, and as far south as the Great Lakes west to Colorado, Nevada, and Oregon. The northern shoveler is one of the species to which the ''Agreement on the Conservation of African-Eurasian Migratory Waterbirds'' (AEWA) applies. The conservation status of this bird is Least Concern. Taxonomy The northern shoveler was first formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his ''Systema Naturae''. He introduced the binomial name ''Anas clypeata''. A molecular phylogentic study ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Common Pochard
The common pochard (; ''Aythya ferina'') is a medium-sized diving duck. The scientific name is derived from Greek '' aithuia'', an unidentified seabird mentioned by authors including Hesychius and Aristotle, and Latin ''ferina'', "wild game", from ''ferus'', "wild". Description The adult male has a long dark bill with a grey band, a red head and neck, a black breast, red eyes and a grey back. The adult female has a brown head and body and a narrower grey bill-band. The triangular head shape is distinctive. Pochards are superficially similar to the closely related North American redhead and canvasback. Females give hoarse growls. Males have whistles cut off by a final nasal note ''aaoo-oo-haa''. Distribution and habitat Their breeding habitat consists of marshes and lakes with a metre or more water depth. Pochards breed in much of temperate and northern Europe and across the Palearctic. They are migratory, and spend winter in the south and west of Europe. In the British Is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Little Ringed Plover
The little ringed plover (''Charadrius dubius'') is a small plover. The genus name ''Charadrius'' is a Late Latin word for a yellowish bird mentioned in the fourth-century Vulgate. It derives from Ancient Greek ''kharadrios'' a bird found in river valleys (''kharadra'', "ravine"). The specific ''dubius'' is Latin for doubtful, since Sonnerat, writing in 1776, thought this bird might be just a variant of common ringed plover. Description Adult little ringed plovers have a grey-brown back and wings, a white belly and a white breast with one black neckband. They have a brown cap, a white forehead, a black mask around the eyes with white above and a short dark bill. The legs are flesh-coloured and the toes are all webbed. This species differs from the larger ringed plover in leg colour, the head pattern, and the presence of a clear yellow eye-ring.
