Haldon Hills
The Haldon Hills, usually known simply as Haldon, is a ridge of high ground in Devon, England. It is situated between the River Exe and the River Teign and runs northwards from Teignmouth, on the coast, for about until it dwindles away north west of Exeter at the River Yeo, just south of Crediton. The highest points of just over 250 metres (820 ft) lie to the south west of Exeter. The southernmost part is known as Little Haldon; it is partially separated from the main bulk of the hills by a col formed by the valleys of the Dawlish Water to the east and the valley at Rixdale to the west. Geology Haldon is composed of New Red Sandstone covered by a more resistant layer of Upper Greensand. On the highest ground is a layer of gravel containing many flints that is up to 18 metres (60 ft) deep; it is all that remains of a cover of chalk some 180 metres (600 ft) thick that was deposited during the Late Cretaceous and then dissolved away during the tr ...

Devonian
The Devonian ( ) is a period (geology), geologic period and system (stratigraphy), system of the Paleozoic era (geology), era during the Phanerozoic eon (geology), eon, spanning 60.3 million years from the end of the preceding Silurian period at million years ago (Megaannum, Ma), to the beginning of the succeeding Carboniferous period at Ma. It is the fourth period of both the Paleozoic and the Phanerozoic. It is named after Devon, South West England, where rocks from this period were first studied. The first significant evolutionary radiation of history of life#Colonization of land, life on land occurred during the Devonian, as free-spore, sporing land plants (pteridophytes) began to spread across dry land, forming extensive coal forests which covered the continents. By the middle of the Devonian, several groups of vascular plants had evolved leaf, leaves and true roots, and by the end of the period the first seed-bearing plants (Pteridospermatophyta, pteridospermatophyt ...

Eurasian Hobby
The Eurasian hobby (''Falco subbuteo'') or just hobby, is a small, slim falcon. It belongs to a group of similar falcons often considered a subgenus '' Hypotriorchis''. Taxonomy and systematics The first formal description of the Eurasian hobby was by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his ''Systema Naturae'' under the present binomial name ''Falco subbuteo''. The genus name ''falco'' derives from Late Latin ''falx'', ''falcis'', a sickle, referring to the wing profile of the bird. The species name ''subbuteo'' is from Latin ''sub'', "below, less than, under" and ''buteo'', "buzzard". The species' English name comes from Old French ''hobé'' or ''hobet''. It became the trademark for the Subbuteo games company after its creator, who was an ornithologist, was refused permission to register "Hobby". Two subspecies are recognized: * ''F. s. subbuteo'': the nominate race is resident in Africa, Europe and Central and East Asia, winters in Central an ...

European Honey Buzzard
The European honey buzzard (''Pernis apivorus''), also known as the pern or common pern, is a bird of prey in the family Accipitridae. Taxonomy The European honey buzzard was formally described in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his ''Systema Naturae''. He placed it with the falcons and eagles in the genus '' Falco'' and coined the binomial name ''Falco apivorus''. Linnaeus cited earlier works including the 1678 description by the English naturalist Francis Willughby and the 1713 description by John Ray. The European honey buzzard is now one of four species placed in the genus '' Pernis'' that was introduced by Georges Cuvier in 1816. The species is monotypic: no subspecies are recognised. The binomen is derived from Ancient Greek ''pernes'' πέρνης, a term used by Aristotle for a bird of prey, and Latin ''apivorus'' "bee-eating", from ''apis'', " bee" and ''-vorus'', "-eating". In fact, bees are much less important than wasps in the bi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bird Of Prey
Birds of prey or predatory birds, also known as (although not the same as) raptors, are hypercarnivorous bird species that actively predation, hunt and feed on other vertebrates (mainly mammals, reptiles and smaller birds). In addition to speed and strength, these predators have bird vision, keen eyesight for detecting prey from a distance or during flight, strong feet with sharp talon (anatomy), talons for grasping or killing prey, and powerful, curved beaks for tearing off flesh. Although predatory birds primarily hunt live prey, many species (such as fish eagles, vultures and condors) also scavenge and eat carrion. Although the term "bird of prey" could theoretically be taken to include all birds that actively hunt and eat other animals, ornithologists typically use the narrower definition followed in this page, excluding many piscivorous predators such as storks, Crane (bird), cranes, herons, gulls, skuas, penguins, and kingfishers, as well as many primarily insectivorous bir ...

European Nightjar
The European nightjar (''Caprimulgus europaeus''), common goatsucker, Eurasian nightjar or just nightjar is a crepuscular and nocturnal bird in the nightjar family that breeds across most of Europe and the Palearctic to Mongolia and Northwestern China. The Latin generic name refers to the old myth that the nocturnal nightjar suckled from goats, causing them to cease to give milk. The six subspecies differ clinally, the birds becoming smaller and paler towards the east of the range. All populations are migratory, wintering in sub-Saharan Africa. Their densely patterned grey and brown plumage makes individuals difficult to see in the daytime when they rest on the ground or perch motionless along a branch, although the male shows white patches in the wings and tail as he flies at night. The preferred habitat is dry, open country with some trees and small bushes, such as heaths, forest clearings or newly planted woodland. The male European nightjar occupies a territory in sprin ...

Haldon Belvedere
Haldon Belvedere or Lawrence Tower is a triangular tower in the Haldon Hills in the county of Devon, England. Haldon Belvedere is in the parish of Dunchideock within the former Haldon estate, about a mile south-west of Haldon House. Its location on the ridge of the Haldon Hills gives it extensive views and means it is a prominent landmark for many miles around.Cherry & Pevsner, p.342 It was built in 1788 by Sir Robert Palk, 1st Baronet and was originally called Lawrence Tower in honour of his friend and patron General Stringer Lawrence (1697–1775). Lawrence spent much of his retirement at Haldon and was buried in Dunchideock church, in which Palk erected a monument to his memory, having received a bequest of £50,000 in his will. Stringer Lawrence's other monument is in Westminster Abbey, erected by the East India Company. The tower, 26 metres high, is triangular with Gothic windows and full-height circular angle turrets, and was probably influenced by the triangular tower at ...

Site Of Special Scientific Interest
A Site of Special Scientific Interest (SSSI) in Great Britain, or an Area of Special Scientific Interest (ASSI) in the Isle of Man and Northern Ireland, is a conservation designation denoting a protected area in the United Kingdom and Isle of Man. SSSI/ASSIs are the basic building block of site-based nature conservation legislation and most other legal nature/geological conservation designations in the United Kingdom are based upon them, including national nature reserve (United Kingdom), national nature reserves, Ramsar Convention, Ramsar sites, Special Protection Areas, and Special Area of Conservation, Special Areas of Conservation. The acronym "SSSI" is often pronounced "triple-S I". Selection and conservation Sites notified for their Biology, biological interest are known as Biological SSSIs (or ASSIs), and those notified for geological or Physical geography, physiographic interest are Geological SSSIs (or ASSIs). Sites may be divided into management units, with some a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Barite
Baryte, barite or barytes ( or ) is a mineral consisting of barium sulfate (Ba S O4). Baryte is generally white or colorless, and is the main source of the element barium. The ''baryte group'' consists of baryte, celestine (strontium sulfate), anglesite (lead sulfate), and anhydrite (calcium sulfate). Baryte and celestine form a solid solution . Names and history The radiating form, sometimes referred to as ''Bologna Stone'', attained some notoriety among alchemists for specimens found in the 17th century near Bologna by Vincenzo Casciarolo. These became phosphorescent upon being calcined. Carl Scheele determined that baryte contained a new element in 1774, but could not isolate barium, only barium oxide. Johan Gottlieb Gahn also isolated barium oxide two years later in similar studies. Barium was first isolated by electrolysis of molten barium salts in 1808 by Sir Humphry Davy in England. The American Petroleum Institute specification API 13/ISO 13500, which governs '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
