Thermostat. a mercury thermostat to regulate the temperature of a chicken incubator. This is one of the first recorded feedback-controlled devices.Modern thermostat control was developed in the 1830s by Andrew Ure (1778–1857), a Scottish chemist, who invented the bi-metallic thermostat. The textile mills of the time needed a constant and steady temperature to operate optimally, so to achieve this Ure designed the bimetallic thermostat, which would bend as one of the metals expanded in response to the increased temperature and cut off the energy supply.Warren S. Johnson (1847–1911) of Wisconsin patented a bi-metal room thermostat in 1883, and two years later.

Thermostat. a heating or cooling system via a series of air-filled control tubes. This "control air" system responds to the pressure changes (due to temperature) in the control tube to activate heating or cooling when required. The control air typically is maintained on "mains" at 15-18 psi (although usually operable up to 20 psi). Pneumatic thermostats typically provide output/ branch/ post-restrictor (for single-pipe operation) pressures of 3-15 psi which is piped to the end device (valve/ damper actuator/ pneumatic-electric switch, etc.).The pneumatic thermostat was invented by Warren Johnson in 1895 soon after he invented the electric thermostat. In 2009, Harry Sim.

Allis shad. The allis shad ("Alosa alosa") is a widespread Northeast Atlantic species of fish in the herring family, Clupeidae. It is an anadromous fish which migrates into fresh water to spawn. It is found in the eastern Atlantic Ocean, the western Baltic Sea and the western Mediterranean Sea. In appearance it resembles an Atlantic herring but has a distinctive dark spot behind the gill cover and sometimes a row of up to six spots behind this. It sometimes hybridises with the twait shad ("A. fallax"). This fish becomes mature when three or more years old and migrates to estuaries, later swimming.

Allis shad. occurs just behind the gill cover, and occasionally one to six smaller spots behind that. The adult length is typically 30 to 60 (cm).## Distribution.The allis shad is found in the eastern Atlantic in waters bordering most of Europe and northwestern Africa, and it enters to the western Baltic and western Mediterranean Seas, but it is rare outside France.## Biology and lifecycle."Alosa alosa" has a similar lifecycle to that of the twait shad "A. fallax". They are known to live in sympatry, and the two species can hybridize. They are anadromous species like many other species in the genus "Alosa".

Allis shad. However, some record of them being landlocked suggests an ability to adapt well to their environment.They primarily live at sea on feeding grounds and migrate to their spawning grounds between April and June once they are sexually mature. Maturity usually ranges from 3–7 years of age. "A. alosa" can usually only reproduce once in their lifetimes. Juveniles appear in estuaries and brackish water around July to August. The salinity of brackish water may pose problems to the juveniles migrating from fresh water.## Population reduction.Populations have been reduced primarily by overfishing, pollution, and habitat destruction. The estuarine phase, or the time.

Allis shad. that they are in the estuaries migrating from spawning grounds to sea, is estimated to have a duration in "A. alosa" of up to six months. The estimate, however, does not take into account individual variation and/or survival of juveniles in the estuarine phase.## Conservation.Four special areas of conservation have been designated in Ireland where "Alosa" species have been known to spawn. "Alosa alosa" "has been placed in Appendix III of the Bern Convention (1979) that lists protected fauna species as well as in Appendix II and V of the European Community Habitats Directive (1992) that list, respectively, species whose.

Allis shad. conservation requires the designation of special areas of conservation and that are subject to management measures." However, "A. alosa" is currently under a moratorium (2008) in numerous French watersheds. EU LIFE-Project: The re-introduction of allis shad ("Alosa alosa") in the Rhine system.

Picea sitchensis. Picea sitchensis, the Sitka spruce, is a large, coniferous, evergreen tree growing to almost 100 (m) tall, with a trunk diameter at breast height that can exceed 5 m (16 ft). It is by far the largest species of spruce and the fifth-largest conifer in the world (behind giant sequoia, coast redwood, kauri, and western red cedar), and the third-tallest conifer species (after coast redwood and coast Douglas fir). The Sitka spruce is one of the few species documented to exceed 90 (m) in height. Its name is derived from the community of Sitka in southeast Alaska, where it is.

Picea sitchensis. prevalent. Its range hugs the western coast of Canada and the US, continuing south into northernmost California.## Description.The bark is thin and scaly, flaking off in small, circular plates 5 – 20 (cm) across. The inner bark is reddish-brown. The crown is broad conic in young trees, becoming cylindric in older trees; old trees may not have branches lower than 30 – 40 (m). The shoots are very pale buff-brown, almost white, and glabrous (hairless), but with prominent pulvini. The leaves are stiff, sharp, and needle-like, 15–25 millimeters long, flattened in cross-section, dark glaucous blue-green above with two or three.

Picea sitchensis. thin lines of stomata, and blue-white below with two dense bands of stomata.The cones are pendulous, slender cylindrical, 6 – 10 (cm) long and 2 (cm) broad when closed, opening to 3 (cm) broad. They have thin, flexible scales 15 – 20 (mm) long; the bracts just above the scales are the longest of any spruce, occasionally just exserted and visible on the closed cones. They are green or reddish, maturing pale brown 5–7 months after pollination. The seeds are black, 3 (mm) long, with a slender, 7 – 9 (mm) long pale brown wing.## Size.More than a century of.

Picea sitchensis. logging has left only a remnant of the spruce forest. The largest trees were cut long before careful measurements could be made. Trees over 90 (m) tall may still be seen in Pacific Rim National Park and Carmanah Walbran Provincial Park on Vancouver Island, British Columbia (the Carmanah Giant, at 96 (m) tall, is the tallest tree in Canada), and in Olympic National Park, Washington and Prairie Creek Redwoods State Park, California (United States); two at the last site are just over 96 m tall. The Queets Spruce is the largest in the world with a trunk volume of 346.

Picea sitchensis. (m3), a height of 74.6 (m), and a 4.4 (m) dbh. It is located near the Queets River in Olympic National Park, about 26 (km) from the Pacific Ocean. Another specimen, from Klootchy Creek Park, Oregon, was previously recorded to be the largest with a circumference of 15 (m) and height of 66 (m).## Age.Sitka spruce is a long-lived tree, with individuals over 700 years old known. Because it grows rapidly under favorable conditions, large size may not indicate exceptional age. The Queets Spruce has been estimated to be only 350 to 450 years old, but adds more than a.

Picea sitchensis. cubic meter of wood each year.## Root system.Because it grows in extremely wet and poorly-drained soil, the Sitka spruce has a shallow root system with long lateral roots and few branchings. This also makes it susceptible to wind throw.## Taxonomy.DNA analysis has shown that only "P. breweriana" has a more basal position than Sitka spruce to the rest of the spruce. The other 33 species of spruce are more derived, which suggests that "Picea" originated in North America.## Distribution and habitat.Sitka spruce is native to the west coast of North America, with its northwestern limit on Kenai Peninsula, Alaska, and.

Picea sitchensis. its southeastern limit near Fort Bragg in northern California. It is closely associated with the temperate rainforests and is found within a few kilometers of the coast in the southern portion of its range. North of Oregon, its range extends inland along river floodplains, but seldom does its range extend more than around 80 (km) from the Pacific Ocean and its inlets. It is situated at about 2500 (m) above sea level in Alaska and generally below 450 (m) further south.Forests with the species average between 200 to 500 (cm) of rain annually. It is tolerant to salty spray common.

Picea sitchensis. in coastal dune habitat, such as at Cape Disappointment State Park in Washington, and prefers soils high in magnesium, calcium, and phosphorus.Sitka spruce has been introduced to Europe as a lumber tree, and was first planted there in the 19th century. Sitka spruce plantations have become a dominant forest type in Great Britain and Ireland, making up 25% of forest cover in the former and 52% in the latter. Sitka spruce woodland is also present in France and Denmark, and the plant was introduced to Iceland and Norway in the early 20th century.A 9-metre-tall, 100-year-old, Sitka spruce sitting in the.

Picea sitchensis. middle of the permanently uninhabited sub-antarctic Campbell Island has been recognised by the Guinness World Records as the "most remote tree in the world".## Ecology.## Value to wildlife.Sitka spruce provides critical habitat for a large variety of mammals, birds, reptiles, and amphibians. Its thick, sharp needles are poor browse for ungulates, and only the new spring growth is eaten. However, in Alaska and British Columbia the needles of "picea sitchensis" comprise up to 90% of the winter diet of blue grouse.It provides cover and hiding places for a large variety of mammals, and good nesting and roosting habitat for birds.

Picea sitchensis. Sitka deer require old-growth Sitka spruce forests for winter habitat, as the extensive foliage holds a significant percentage of fallen snow in a given area, thus allowing for better understory browsing and easier migration for terrestrial animals. Cavity nesting birds favor Sitka spruce snags, and the tree is used by bald eagles and peregrine falcons as nesting habitat.## Successional status.Sitka spruce is shade tolerant but not as much as its competitors, preferring full sun if possible. It is a pioneer on landslides, sand dunes, uplifted beaches, and deglaciated terrain. However, it is a climax species in coastal forests, where it.

Picea sitchensis. can become dominant.## Fire ecology.Due to the prevalence of Sitka spruce in cool, wet climates, its thin bark and shallow root system are not adapted to resist fire damage and it is thus very susceptible. Sitka spruce forests have a fire regime of severe crown or surface fires on long intervals, (150 to 350+ years) which results in total stand replacement. Sitka spruce recolonizes burned sites via wind-dispersed seed from adjacent unburned forests.## Uses.The root bark of Sitka spruce trees is used in Native Alaskan basket-weaving designs and for rain hats. The pitch was used for caulking, chewing, and its.

Picea sitchensis. medicinal properties. Native Americans heated and plied the roots to make cord. The resin was used as glue and for waterproofing. Natives and pioneers split off shakes for construction use. The wood is light and relatively strong.Sitka spruce is of major importance in forestry for timber and paper production. Outside its native range, it is particularly valued for its fast growth on poor soils and exposed sites where few other trees can prosper; in ideal conditions, young trees may grow 1.5 (m) per year. It is naturalized in some parts of Ireland and Great Britain, where it was introduced in.

Picea sitchensis. 1831 by David Douglas, and New Zealand, though not so extensively as to be considered invasive. Sitka spruce is also planted extensively in Denmark, Norway, and Iceland. In Norway, Sitka spruce was introduced in the early 1900s. An estimated 50000 (ha) have been planted in Norway, mainly along the coast from Vest-Agder in the south to Troms in the north. It is more tolerant to wind and saline ocean air, and grows faster than the native Norway spruce. But in Norway, the Sitka spruce is now considered an invasive species, and effort to get rid of it is being made.The.

Picea sitchensis. resonant wood is used widely in piano, harp, violin, and guitar manufacture, as its high strength-to-weight ratio and regular, knot-free rings make it an excellent conductor of sound. For these reasons, the wood is also an important material for sailboat spars, and aircraft wing spars (including flying models). The Wright brothers' Flyer was built using Sitka spruce, as were many aircraft before World War II; during that war, aircraft such as the British Mosquito used it as a substitute for strategically important aluminium.Newly grown tips of Sitka spruce branches are used to flavor spruce beer and are boiled to make.

Crabeater seal. The crabeater seal (Lobodon carcinophaga), also known as the krill-eater seal, is a true seal with a circumpolar distribution around the coast of Antarctica. They are medium- to large-sized (over 2 m in length), relatively slender and pale-colored, found primarily on the free-floating pack ice that extends seasonally out from the Antarctic coast, which they use as a platform for resting, mating, social aggregation and accessing their prey. They are by far the most abundant seal species in the world. While population estimates are uncertain, there are at least 7 million and possibly as many as 75 million individuals. This.

Crabeater seal. name of the crabeater seal, "Lobodon", derives from Ancient Greek meaning "lobe-toothed", and the species name "carcinophaga" means "crab eater." The crabeater seal shares a common recent ancestor with the other Antarctic seals, which are together known as the lobodontine seals. These include the leopard seal ("Hydrurga leptonyx"), the Ross seal ("Ommatophoca rossii"), and the Weddell seal ("Leptonychotes weddelli"). These species, collectively belonging to the Lobodontini tribe of seals, share teeth adaptations including lobes and cusps useful for straining smaller prey items out of the water column. The ancestral Lobodontini likely diverged from their sister clade, the Mirounga (elephant seals).

Brown recluse spider. The brown recluse, Loxosceles reclusa, Sicariidae (formerly placed in a family "Loxoscelidae") is a recluse spider with necrotic venom. Similar to those of other recluse spiders, their bites sometimes require medical attention. The brown recluse is one of three spiders in North America with medically significant venom, the others being the black widow and the Chilean recluse.Brown recluse spiders are usually between 6 ( and ), but may grow larger. While typically light to medium brown, they range in color from whitish to dark brown or blackish gray. The cephalothorax and abdomen are not necessarily the same color. These spiders.

Brown recluse spider. in California or anywhere outside its native range. There are other species of the genus "Loxosceles" native to the southwestern part of the United States, including California, which may resemble the brown recluse, but interactions between humans and the recluse species in California and the region are rare because those species native ranges lie outside of dense human populations. The number of "false positive" reports based on misidentifications is considerable; in a nationwide study where people submitted spiders that they thought were brown recluses, of 581 from California only 1 was a brown recluse—submitted by a family that moved from.

Brown recluse spider. (e.g., in several such cases in Florida), but do not spread, and can be easily eradicated. The spider has also received numerous sensationalized media reports of bites occurring where these spiders are absent (and no specimens were found), such as a 2014 report from Thailand, where a man was claimed to have died from a brown recluse bite. Many misidentifications and erroneous geographic records stem from the similarity between "L. reclusa" and a related introduced species, the Mediterranean recluse ("Loxosceles rufescens"), which is found worldwide, including numerous sightings throughout the United States; the two species are superficially almost indistinguishable, and.

Brown recluse spider. which tend to remain nearer to their webs.## Bite."Loxosceles reclusa" (as with all of the "Loxosceles" genus) can deliver, through envenomation via uncate chelicerae-type fangs, a potentially dermonecrotic loxoscelism due to the presence of sphingomyelinase D toxin in its venom. Most bites are minor with no dermonecrosis. However, a small number of brown recluse bites do produce dermonecrotic loxoscelism; an even smaller number produce severe cutaneous (skin) or viscerocutaneous (systemic) symptoms. In one study of clinically diagnosed brown recluse bites, skin necrosis occurred 37% of the time, while systemic illness occurred 14% of the time. In these cases, the bites.

Brown recluse spider. produced a range of symptoms common to many members of the genus "Loxosceles" known as loxoscelism, which may be cutaneous and viscerocutaneous. In very rare cases, bites can even cause hemolysis—the bursting of red blood cells.As suggested by its specific name "reclusa" (recluse), the brown recluse spider is rarely aggressive, and bites from the species are uncommon. In 2001, more than 2,000 brown recluse spiders were removed from a heavily infested home in Kansas, yet the four residents who had lived there for years were never harmed by the spiders, despite many encounters with them.

Barbarea vulgaris. Barbarea vulgaris, also called wintercress (usual common name), or alternatively herb barbara, rocketcress, yellow rocketcress, winter rocket, yellow rocket, and wound rocket, is a biennial herb of the genus "Barbarea", belonging to the family Brassicaceae.## Description.This plant grows to about 30 - 60 (cm) high, with a maximum of 1 (m). The stem is ribbed and hairless, branched at the base. It has basal rosettes of shiny, dark green leaves. The basal leaves are stalked and lyre-pinnatifid, that is with a large terminal lobe and smaller lower lobes. The cauline leaves are smaller, ovate, toothed, or lobed. The flowers are.

Barbarea vulgaris. borne in spring in dense terminal clusters above the foliage. They are 7 - 9 (mm) long, with four bright yellow petals. The flowering period extends from about April through July. The fruit is a pod around 15 - 30 (mm).Chemical substances in this species include saponins, flavonoids, and glucosinolates.## Taxonomy.Formally, "B. vulgaris" was first published and described by William Aiton in his 'Hortus Kewensis' Vol.4 on page 109 in 1812. Some references still mention Robert Brown (Robert Brown (botanist, born 1773)), as the author. Indeed, botanists believe that R. Brown was the actual author of the first botanical description.

Barbarea vulgaris. of "B. vulgaris" in the description of the family Brassicaceae (in Hortus Kew. ed. 2). However, W. T. Aiton, the publishing author, did not mention or indicate R. Brown's name for Brassicaceae; therefore, W. T. Aiton is author of the Brassicaceae novelties in this work. "B. vulgaris" has various common names of which the most commonly used is 'wintercress' (e.g. Gleason, H.A. Illustrated Flora of the NE United States and Adjacent Canada, 1952), which can also be used for the entire genus "Barbarea". Many other common names are listed in various sources, including (in alphabetical order), 'cressy-greens', 'English wintercress', 'herb-Barbaras',.

Barbarea vulgaris. 'rocket cress', and 'yellow rocket'. Two additional names sometimes used, 'bittercress' and 'upland cress' are ambiguous; the name 'bittercress' usually signifies various species of the genus "Cardamine", and 'upland cress' usually signifies "Barbarea verna".## Etymology.The genus name "Barbarea" derives from Saint Barbara, the patron saint of artillerymen and miners, as this plant in the past was used to soothe the wounds caused by explosions. The species Latin name "vulgaris" means “common”.## Natural insect resistance and its potential use in agriculture.Most "B. vulgaris" genotypes are naturally resistant to some insect species that are otherwise specialized on the crucifer family. In the.

Barbarea vulgaris. case of diamondback moth ("Plutella xylostella") and the flea beetle "Phyllotreta nemorum", the resistance is caused by saponins. Glucosinolates such as glucobarbarin and glucobrassicin are used as a cue for egg-laying by female cabbage white butterflies such as "Pieris rapae". Indeed, the larvae of this butterfly thrive well on this plant. Diamondback moth females are also stimulated by these chemicals, but the larvae die due to the content of saponins which are apparently not sensed by the moths. This phenomenon has been tested for biological insect control: "B. vulgaris" plants are placed in a field and attract much of the.

Barbarea vulgaris. diamondback moth egg load. As the larvae die shortly after hatching, this kind of insect control has been named "dead-end trap cropping".## Distribution.Native to Eurasia and North Africa, it is naturalised in many parts of North America and New Zealand as a weed.## Range.It is found in temperate North Africa within Algeria and Tunisia. Also in Asia, within Afghanistan, Armenia, Azerbaijan, the Caucasus, China (in the provinces of Heilongjiang, Jiangsu, Jilin and Xinjiang), Georgia, Iran, Iraq, Japan (in the provinces Hokkaido, Honshu, Kyushu, Ryukyu Islands and Shikoku), Kazakhstan, Kyrgyzstan, Mongolia, Siberia, Tajikistan, Turkmenistan and Turkey. It is also found in.

In middle Europe, it is in Austria, Belgium, the Czech Republic, Germany, Hungary, the Netherlands, Poland, Slovakia and Switzerland. In northern Europe, in Denmark, Ireland, Sweden and United Kingdom. In southeastern Europe, within Albania, Bosnia and Herzegovina, Bulgaria, Croatia, Greece, Italy, Montenegro, North Macedonia, Romania, Serbia and Slovenia. Lastly, it is found in southwestern Europe, it is found in France,.

Barbarea vulgaris. Portugal and Spain.## Habitat.The plant prefers fresh or moist places, on roadsides, along rivers, in arable land, wastelands and docklands, or on the slopes and in ditches, at an altitude of 0 - 2500 (m) above sea level.It also prefers to grow in siliceous, calcareous, sandy, alluvial and clay soils.## Natural chemotypes with distinct ecology.A pubescent type (the "P-type") has been described from southern Scandinavia and Russia. While this chemotype is rare in Scandinavia, it seems to be dominant in Russia according to the only survey made so far. This type has atypical chemistry and is devoid of resistance to.

Barbarea vulgaris. the diamondback moth and the flea beetle "Phyllotreta nemorum". The P-type belongs morphologically to the variety "B. vulgaris" var. "arcuata", but may also be identical to the variety originally described as "Barbarea" "arcuata" Rchb. var. "pubescens" N. Busch. In this context, the usual type of "B. vulgaris" var. "arcuata" is called the "G-type" (for glabrous (hairless) leaves). This type is reported to be dominant in Central Europe. On a genomic scale, more than 22.000 genes (89% of those tested) were found to have fixed differences between the two types.A chemotype with deviating glucosinolate content has been described from Western and.

Barbarea vulgaris. Central Europe and named the "NAS-type" (because it is dominated by the glucosinolate glucoNASturtiin. This type has increased resistance to some specialized insects. In this context, the usual chemotype of "B. vulgaris" is called the "BAR" type (because it is dominated by glucoBARbarin).While the P-type and G-type differ in multiple genetic, chemical and morphological features, the NAS and BAR types seem to be a simple monogenic variation. For this reason, it has been suggested to refer to NAS and BAR forms (from the lowest botanical rank forma) and P- and G-types. Indeed, occasional NAS form plants in Central Europe were.

Barbarea vulgaris. found to be G-type by a set of genetic markers.## Uses.The young leaves can be eaten raw or cooked. The buds and flowers are also edible.

It won the 2003 Emporis Skyscraper Award.## Site and early plans.The building stands on the site of the former Baltic Exchange (24–28 St Mary Axe), which was the headquarters of a global marketplace for shipping freight contracts and soft commodities, and the Chamber of Shipping (30–32 St Mary Axe). The tower's topmost panoramic.

30 St Mary Axe. dome, known as the "lens", recalls the iconic glass dome that covered part of the ground floor of the Baltic Exchange and much of which is now displayed at the National Maritime Museum. "The Gherkin" nickname was applied to the current building at least as early as 1999, referring to the plan's highly unorthodox layout and appearance.On 10 April 1992, the Provisional IRA detonated a bomb close to the Baltic Exchange, causing extensive damage to the historic building and neighbouring structures. The United Kingdom government's statutory adviser on the historic environment, English Heritage, and the City of London's governing body,.

30 St Mary Axe. the City of London Corporation, were keen that any redevelopment must restore the Baltic Exchange's old façade onto St Mary Axe. The Exchange Hall was a celebrated fixture of the shipping market.English Heritage then discovered that the damage was far more severe than initially thought, and they stopped insisting on full restoration, albeit over the objections of architectural conservationists. The Baltic Exchange and the Chamber of Shipping sold the land to Trafalgar House in 1995. Most of the remaining structures on the Baltic Exchange site were then carefully dismantled, and the interior of Exchange Hall and the façade were preserved,.

30 St Mary Axe. hoping for a reconstruction of the building in the future. The salvaged material was eventually sold for £800,000 and moved to Tallinn, Estonia, where it awaits reconstruction as the centrepiece of the city's commercial sector.In 1996, Trafalgar House submitted plans for the London Millennium Tower, a 386 (m) building with more than 140000 (sqm) of office space, apartments, shops, restaurants and gardens. This plan was dropped after objections that it was totally out-of-scale in the City of London, and anticipated disruption to flight paths for both London City and London Heathrow airports; the revised plan for a lower tower was.

30 St Mary Axe. accepted.## Planning process.John Prescott, the Deputy Prime Minister, granted planning permission on 23 August 2000 to construct a building on the site, which would be much larger than the old Exchange. The site needed development, was not on any of the "sight lines" (planning guidance requires that new buildings do not obstruct or detract from the view of St Paul's Cathedral dome when viewed from a number of locations around London), and had housed the Baltic Exchange.The plan for the site was to reconstruct the Baltic Exchange. GMW Architects proposed a new rectangular building surrounding a restored exchange: it would.

30 St Mary Axe. have the type of large floor plan that banks liked. Eventually, the planners realised that the exchange was not recoverable, forcing them to relax their building constraints; they hinted that an "architecturally significant" building might obtain a favourable reception from City authorities. This gave the architect a free hand in the design. The building was designed according to the client's needs, rather than for the needs of a large, capital-efficient, money-making building.The new building's low-level plan satisfied the planning authority's desire to maintain London's traditional streetscape, with its narrow streets. The massing of the tower was not too imposing. Like.

30 St Mary Axe. Barclays' former city headquarters in Lombard Street, the idea was that the passer-by in neighbouring streets would be nearly oblivious to the tower's existence until directly underneath it.## Design and construction.The building was constructed by Skanska, completed in December 2003 and opened on 28 April 2004. The primary occupant of the building is Swiss Re, a global reinsurance company, which had the building commissioned as the head office for its UK operation. The tower is thus sometimes known as the Swiss Re Building, although this name has never been official and was never in popular usage anyway, unlike the Gherkin.

30 St Mary Axe. moniker.The building uses energy-saving methods which allow it to use only half the power that a similar tower would typically consume. Gaps in each floor create six shafts that serve as a natural ventilation system for the entire building, even though required firebreaks on every sixth floor interrupt the "chimney". The shafts create a giant double glazing effect; air is sandwiched between two layers of glazing and insulates the office space inside.Architects promote double glazing in residential houses, which avoids the inefficient convection of heat across the relatively narrow gap between the panes, but the tower exploits this effect. The.

30 St Mary Axe. shafts pull warm air out of the building during the summer and warm the building in the winter using passive solar heating. The shafts also allow sunlight to pass through the building, making the work environment more pleasing, and keeping the lighting costs down.The primary methods for controlling wind-excited sways are to increase the stiffness, or increase damping with tuned/active mass dampers. To a design by Arup, its fully triangulated perimeter structure makes the building rigid enough without any extra reinforcements. Despite its overall curved glass shape, there is only one piece of curved glass on the building, the lens-shaped.

30 St Mary Axe. cap at the apex.On the building's top level (the 40th floor), there is a bar for tenants and their guests, with a panoramic view of London. A restaurant operates on the 39th floor, and private dining rooms on the 38th. Most buildings have extensive lift equipment on the roof of the building, but this was not possible for the Gherkin, since a bar had been planned for the 40th floor. The architects dealt with this by having the main lift only reach the 34th floor, with a separate push-from-below lift to the 39th floor. There is a marble stairwell and.

30 St Mary Axe. a disabled persons' lift, which leads the visitor up to the bar in the dome.The building is visible over long distances: From the north, for instance, it can be seen from the M11 motorway, some 32 (km) away, while to the west it can be seen from the statue of George III in Windsor Great Park.## After completion.In April 2005, a glass panel two thirds up the tower fell to the plaza beneath. The plaza was sealed off, but the building remained open. A temporary covered walkway, extending across the plaza to the building's reception, was erected to protect visitors.

30 St Mary Axe. Engineers examined the other 744 glass panels on the building. The cost of repair was covered by main contractor Skanska and curtain-wall supplier Schmidlin (now called Schmidlin-TSK AG). The open-floor ventilation system did not operate as designed due to tenants adding glass partitions to increase security.Since its completion, the building has won a number of awards for architecture. In October 2004, the architect was awarded the 2004 Stirling Prize. For the first time in the prize's history, the judges were unanimous. In December 2005, a survey of the world's largest firms of architects published in "2006 BD World Architecture 200.

30 St Mary Axe. voted the tower as the most admired new building in the world. However, Ken Shuttleworth, who worked for Foster + Partners on the design of the building, said in 2011 that he believed the style was now out-moded: "I was looking at the glass all around and [thought], 'Why on earth did we do that?' Now we would do things differently". The building appeared in recent films such as "Harry Potter and the Half Blood Prince", "A Good Year", "Basic Instinct 2", and "Match Point" and, rechristened the "Spirit of London", became the spaceship centrepiece of Keith Mansfield's 2008 novel.

30 St Mary Axe. "Johnny Mackintosh and the Spirit of London".In September 2006, the building was put up for sale with a price tag of £600 million. Potential buyers included British Land, Land Securities, Prudential, ING, and the Abu Dhabi royal family. On 21 February 2007, IVG Immobilien AG and UK investment firm Evans Randall completed their joint purchase of the building for £630 million, making it Britain's most expensive office building. Swiss Re made a gain of more than £300 million from the sale. The new owners are seeking compensation from four of their former managers on the deal, in which about £620.

Hexagon. of the circumscribed circle or circumcircle, which equals formula_1 times the apothem (radius of the inscribed circle). All internal angles are 120 degrees. A regular hexagon has six rotational symmetries ("rotational symmetry of order six") and six reflection symmetries ("six lines of symmetry"), making up the dihedral group D6. The longest diagonals of a regular hexagon, connecting diametrically opposite vertices, are twice the length of one side. From this it can be seen that a triangle with a vertex at the center of the regular hexagon and sharing one side with the hexagon is equilateral, and that the regular hexagon.

Hexagon. adding alternating squares and equilateral triangles around it. This pattern repeats within the rhombitrihexagonal tiling.## Self-crossing hexagons.There are six self-crossing hexagons with the vertex arrangement of the regular hexagon:## Hexagonal structures.From bees' honeycombs to the Giant's Causeway, hexagonal patterns are prevalent in nature due to their efficiency. In a hexagonal grid each line is as short as it can possibly be if a large area is to be filled with the fewest hexagons. This means that honeycombs require less wax to construct and gain much strength under compression.Irregular hexagons with parallel opposite edges are called parallelogons and can also tile.

Hexagon. the plane by translation. In three dimensions, hexagonal prisms with parallel opposite faces are called parallelohedrons and these can tessellate 3-space by translation.## Tesselations by hexagons.In addition to the regular hexagon, which determines a unique tessellation of the plane, any irregular hexagon which satisfies the Conway criterion will tile the plane.## Hexagon inscribed in a conic section.Pascal's theorem (also known as the "Hexagrammum Mysticum Theorem") states that if an arbitrary hexagon is inscribed in any conic section, and pairs of opposite sides are extended until they meet, the three intersection points will lie on a straight line, the "Pascal line.

Hexagon. of that configuration.## Cyclic hexagon.The Lemoine hexagon is a cyclic hexagon (one inscribed in a circle) with vertices given by the six intersections of the edges of a triangle and the three lines that are parallel to the edges that pass through its symmedian point.If the successive sides of a cyclic hexagon are "a", "b", "c", "d", "e", "f", then the three main diagonals intersect in a single point if and only if .If, for each side of a cyclic hexagon, the adjacent sides are extended to their intersection, forming a triangle exterior to the given side, then the segments.

Hexagon. connecting the circumcenters of opposite triangles are concurrent.If a hexagon has vertices on the circumcircle of an acute triangle at the six points (including three triangle vertices) where the extended altitudes of the triangle meet the circumcircle, then the area of the hexagon is twice the area of the triangle.## Hexagon tangential to a conic section.Let ABCDEF be a hexagon formed by six tangent lines of a conic section. Then Brianchon's theorem states that the three main diagonals AD, BE, and CF intersect at a single point.In a hexagon that is tangential to a circle and that has consecutive sides.

Hexagon. "a", "b", "c", "d", "e", and "f",formula_16## Equilateral triangles on the sides of an arbitrary hexagon.If an equilateral triangle is constructed externally on each side of any hexagon, then the midpoints of the segments connecting the centroids of opposite triangles form another equilateral triangle.## Skew hexagon.A skew hexagon is a skew polygon with six vertices and edges but not existing on the same plane. The interior of such an hexagon is not generally defined. A "skew zig-zag hexagon" has vertices alternating between two parallel planes.A regular skew hexagon is vertex-transitive with equal edge lengths. In three dimensions it will be.

Black-legged kittiwake. The black-legged kittiwake (Rissa tridactyla) is a seabird species in the gull family Laridae.This species was first described by Carl Linnaeus in his landmark 1758 10th edition of "Systema Naturae" as "Larus tridactylus". The English name is derived from its call, a shrill 'kittee-wa-aaake, kitte-wa-aaake'. The genus name "Rissa" is from the Icelandic name "rita" for this bird, and the specific "tridactyla" is from Ancient Greek "tridaktulos", "three-toed", from "tri-", "three-" and "daktulos", "toe".In North America, this species is known as the black-legged kittiwake to differentiate it from the red-legged kittiwake, but in Europe, where it is the only member.

Black-legged kittiwake. of the genus, it is often known just as kittiwake.## Range and distribution.The black-legged kittiwake is a coastal bird of the arctic to subarctic regions of the world. It can be found all across the northern coasts of the Atlantic, from Canada to Greenland as well as on the Pacific side from Alaska to the coast of Siberia. Black-legged kittiwakes' wintering range extends further south from the St-Lawrence to the southern coast of New Jersey as well as in China, the Sargasso sea and of the coast of west Africa. There are two subspecies of black-legged kittiwake. "Rissa tridactyla tridactyla.

Black-legged kittiwake. can be found on the Atlantic coast whereas "Rissa tridactyla pollicaris" is found on the Pacific coast.Out of all the laridae, the kittiwakes are the most pelagic ones. Kittiwakes are almost exclusively found at sea with the exception of the breeding period, from May to September, where they can be found nesting on the sheerest sea cliffs. They are rarely found inland, though they have been reported on few instances as far as 20 km inland. For the rest of the year, kittiwake spend most of their time on the wing out of sight from the coast.## Description.## Adult plumage.The.

Black-legged kittiwake. will reach an overall colour of bright yellow and complete its mature plumage.The old fisherman's name of "tarrock" for juvenile kittiwakes is still occasionally used.## Similar species.The red-legged kittiwake is the only other species in the Rissa genus and can be differentiated from its counterpart by its red legs, as the name suggests. The head of the red-legged kittiwake is slightly smaller and bears a shorter bill. The chicks of the Pacific black-legged kittiwake and red-legged kittiwake cannot be distinguished during their youngest downy phase.The juvenile black-legged kittiwake can be confused with the Bonaparte's gull juveniles although the kittiwakes' plumage.

Black-legged kittiwake. has more black on the primaries and a different pattern going across the coverts.## Breeding.It is a coastal breeding bird around the north Pacific and north Atlantic oceans, found most commonly in North America and Europe. Kittiwakes are colonial nesters that form monogamous pairs and exhibit biparental care, meaning that both take part in nest building, incubation and chick rearing. They tend to nest in large numbers on cliffs by the sea side. It breeds in large colonies on cliffs and is very noisy on the breeding ground. Cliff nesting for gulls occurs only in the "Rissa" species, and the.

Black-legged kittiwake. in the North Atlantic Ocean, is unique among the Laridae in having only a very small or even no hind toe.

Front de Seine. Front de Seine is a development in the district of Beaugrenelle in Paris, France, located along the river Seine in the 15th arrondissement at the south of the Eiffel Tower. It is, with the 13th arrondissement, one of the few districts in the city of Paris containing highrise buildings, as most have been constructed outside the city (notably in La Défense).The Front de Seine district is the result of an urban planning project from the 1970s. It includes about 20 towers reaching nearly 100 m of height built all around an elevated esplanade. That esplanade is paved with frescos that.

Front de Seine. can be seen only from the elevated floors of the towers. As opposed to Italie 13, the design of the towers is much more varied. The Hôtel Novotel Paris-Tour Eiffel (formerly known as Hôtel Nikkō), for instance, has red-encircled windows, while the Tour Totem consists of a stack of several glazed blocks.A newly redesigned shopping centre, the Centre commercial Beaugrenelle opened in 2013.Furthermore, while 13th arrondissement towers are predominantly residential and La Défense towers are predominantly commercial, the towers of the Front de Seine are of mixed commercial and residential use.

Vipera berus. a few days. Adults grow to a total length (including tail) of 60 to 90 (cm) and a mass of 50 to 180 (g). Three subspecies are recognized, including the nominate subspecies, "Vipera berus berus" described here. The snake is not considered to be threatened, though it is protected in some countries.## Taxonomy.The species has three recognised subspecies:The subspecies "V. b. bosniensis" and "V. b. sachalinensis" have been regarded as full species in some recent publications.The name 'adder' is derived from "nædre", an Old English word that had the generic meaning of serpent in the older forms of many Germanic.

Vipera berus. "common cross adder".In Denmark, Norway and Sweden, the snake is known as "hugorm", "hoggorm" and "huggorm", roughly translated as 'striking snake'. In Finland, it is known as "kyykäärme" or simply "kyy", in Estonia it is known as "rästik", while in Lithuania it is known as "angis". In Poland the snake is called "żmija zygzakowata," which translates as 'zigzag viper', due to the pattern on its back.## Description.Relatively thick-bodied, adults usually grow to 60 (cm) in total length (including tail), with an average of 55 (cm). Maximum size varies by region. The largest, at over 90 (cm), are found in Scandinavia;.

Vipera berus. a tiny scale between the frontal and the parietals), and two long and narrow supraoculars. The latter are large and distinct, each separated from the frontal by one to four small scales. The nostril is situated in a shallow depression within a large nasal scale.The eye is relatively large—equal in size or slightly larger than the nasal scale—but often smaller in females. Below the supraoculars are six to 13 (usually eight to 10) small circumorbital scales. The temporal scales are smooth (rarely weakly keeled). There are 10–12 sublabials and six to 10 (usually eight or 9) supralabials. Of the latter,.

Vipera berus. the numbers 3 and 4 are the largest, while 4 and 5 (rarely 3 and 4) are separated from the eye by a single row of small scales (sometimes two rows in alpine specimens).Midbody there are 21 dorsal scales rows (rarely 19, 20, 22, or 23). These are strongly keeled scales, except for those bordering the ventral scales. These scales seem loosely attached to the skin and lower rows become increasingly wide; those closest to the ventral scales are twice as wide as the ones along the midline. The ventral scales number 132–150 in males and 132–158 in females. The.

It is found farther north than any other snake species. The type locality was originally listed as 'Europa'. Mertens and Müller (1940) proposed restricting the type locality to 'Upsala, Schweden' (Uppsala, Sweden) and it was eventually restricted to Berthåga, Uppsala by designation of a neotype by Krecsák & Wahlgren (2008).In several European countries, it is notable as being the only native venomous snake. It is one of.

Vipera berus. and thus may be found on the banks of streams, lakes, and ponds.In much of southern Europe, such as southern France and northern Italy, it is found in either low lying wetlands or at high altitudes. In the Swiss Alps, it may ascend to about 3000 (m). In Hungary and Russia, it avoids open steppeland; a habitat in which "V. ursinii" is more likely to occur. In Russia, however, it does occur in the forest steppe zone.## Conservation status.In Great Britain, it is illegal to kill, injure, harm or sell adders under the Wildlife and Countryside Act 1981. The same.

Vipera berus. situation applies to Norway under the (The Wildlife Act 1981) and Denmark (1981). The common viper is categorised as 'endangered' in Switzerland, and is also protected in some other countries in its range. It is also found in many protected areas.This species is listed as protected (Appendix III) under the Berne Convention. Despite the convention, it is not protected in Finland because of a reservation.The International Union for Conservation of Nature Red List of Threatened Species describes the conservation status as of 'least concern' in view of its wide distribution, presumed large population, broad range of habitats, and likely slow.

Vipera berus. species is cold-adapted and hibernates in the winter. In Great Britain, males and females hibernate for about 150 and 180 days, respectively. In northern Sweden hibernation lasts 8–9 months. On mild winter days, they may emerge to bask where the snow has melted and will often travel across snow. About 15% of adults and 30–40% of juveniles die during hibernation.## Feeding.Diet consists mainly of small mammals, such as mice, rats, voles, and shrews, as well as lizards. Sometimes, slow worms are taken, and even weasels and moles. Adders also feed on amphibians, such as frogs, newts, and salamanders. Birds are.

In this act, the males confront each other, raise up the front part of the body vertically, make swaying movements and attempt to push each other to the ground. This is repeated until one of the two becomes exhausted and crawls off to find another mate. Appleby (1971) notes that he has never seen an intruder win one of these contests, as if the frustrated defender is so aroused by courtship that he refuses to lose his chance to mate. There is no record of any biting taking place during these bouts.Females.

As a comparison, in one test the minimum lethal dose of venom for a guinea pig was 40–67 mg, but only 1.7 mg was necessary when "Daboia russelii" venom was used. Brown (1973) gives a higher subcutaneous LD50 range of 1.0–4.0 mg/kg. All agree that the venom yield is low: Minton (1974) mentions 10–18 mg for specimens 48 – 62 (cm) in length, while Brown (1973) lists only.

Vipera berus. 6 mg.Relatively speaking, bites from this species are not highly dangerous. In Britain there were only 14 known fatalities between 1876 and 2005—the last a 5-year-old child in 1975—and one nearly fatal bite of a 39-year-old woman in Essex in 1998. An 82-year-old woman died following a bite in Germany in 2004, although it is not clear whether her death was due to the effect of the venom. A 44-year-old British man was left seriously ill after he was bitten by an adder in the Dalby Forest, Yorkshire. Even so, professional medical help should always be sought as soon as.

Tetrahedron. of a tetrahedron the base is a triangle (any of the four faces can be considered the base), so a tetrahedron is also known as a "triangular pyramid".Like all convex polyhedra, a tetrahedron can be folded from a single sheet of paper. It has two such nets.For any tetrahedron there exists a sphere (called the circumsphere) on which all four vertices lie, and another sphere (the insphere) tangent to the tetrahedron's faces.## Regular tetrahedron.A regular tetrahedron is a tetrahedron in which all four faces are equilateral triangles. It is one of the five regular Platonic solids, which have been known.

Tetrahedron. edge of the base. This follows from the fact that the medians of a triangle intersect at its centroid, and this point divides each of them in two segments, one of which is twice as long as the other (see ).For a regular tetrahedron with side length "a", radius "R" of its circumscribing sphere, and distances "di" from an arbitrary point in 3-space to its four vertices, we haveformula_7## Isometries of the regular tetrahedron.The vertices of a cube can be grouped into two groups of four, each forming a regular tetrahedron (see above, and also , showing one of the.

Tetrahedron. with four congruent triangles as faces; the triangles necessarily have all angles acute. The regular tetrahedron is a special case of a disphenoid. Other names for the same shape include bisphenoid, isosceles tetrahedron and equifacial tetrahedron.## Orthoschemes.A 3-orthoscheme is a tetrahedron where all four faces are right triangles. An orthoscheme is an irregular simplex that is the convex hull of a tree in which all edges are mutually perpendicular. In a 3-dimensional orthoscheme, the tree consists of three perpendicular edges connecting all four vertices in a linear path that makes two right-angled turns. The 3-orthoscheme is a tetrahedron having two.

Tetrahedron. its characteristic tetrahedron by its planes of symmetry.If the tetrahedron has edge length 2, its characteristic tetrahedron's six edges have lengths , , (the exterior right triangle face, the "characteristic triangle" of the tetrahedron), plus , , (edges that are the "characteristic radii" of the tetrahedron). The 3-edge path along orthogonal edges of the orthoscheme is , , , first from a tetrahedron vertex to an tetrahedron edge center, then turning 90° to an tetrahedron face center, then turning 90° to the tetrahedron center. The orthoscheme has four dissimilar right triangle faces. The exterior face is a 30-60-90 triangle which.

Tetrahedron. is one-sixth of a tetrahedron face. The three faces interior to the tetrahedron are: a right triangle with edges , , , a right triangle with edges , , , and a right triangle with edges , , .## Space-filling tetrahedra.A space-filling tetrahedron packs with directly congruent or enantiomorphous (mirror image) copies of itself to tile space. The cube can be dissected into six 3-orthoschemes, three left-handed and three right-handed (one of each at each cube face), and cubes can fill space, so the characteristic 3-orthoscheme of the cube is a space-filling tetrahedron in this sense. A disphenoid can be.

Let be the volume of the tetrahedron; thenformula_19whereformula_20The above formula uses six lengths of edges, and the following formula uses three lengths of edges and three angles.formula_21## Heron-type formula for the volume of a tetrahedron.If , , , , , are lengths of edges of the tetrahedron (first three form a triangle; with opposite , opposite , opposite ), thenformula_22where formula_23 formula_24## Volume divider.Any plane containing a bimedian (connector of opposite edges' midpoints) of a tetrahedron bisects the volume of the tetrahedron.## Non-Euclidean volume.For.

Tetrahedron. as calculated here. Then another volume formula is given byformula_25## Properties analogous to those of a triangle.The tetrahedron has many properties analogous to those of a triangle, including an insphere, circumsphere, medial tetrahedron, and exspheres. It has respective centers such as incenter, circumcenter, excenters, Spieker center and points such as a centroid. However, there is generally no orthocenter in the sense of intersecting altitudes.Gaspard Monge found a center that exists in every tetrahedron, now known as the Monge point: the point where the six midplanes of a tetrahedron intersect. A midplane is defined as a plane that is orthogonal to.

Tetrahedron. segment joining the midpoints of two opposite edges is called a "bimedian" of the tetrahedron. Hence there are four medians and three bimedians in a tetrahedron. These seven line segments are all concurrent at a point called the "centroid" of the tetrahedron. In addition the four medians are divided in a 3:1 ratio by the centroid (see Commandino's theorem). The centroid of a tetrahedron is the midpoint between its Monge point and circumcenter. These points define the "Euler line" of the tetrahedron that is analogous to the Euler line of a triangle.The nine-point circle of the general triangle has an.

Tetrahedron. face.The radius of the twelve-point sphere is one third of the circumradius of the reference tetrahedron.There is a relation among the angles made by the faces of a general tetrahedron given byformula_26where "α" is the angle between the faces "i" and "j".The geometric median of the vertex position coordinates of a tetrahedron and its isogonic center are associated, under circumstances analogous to those observed for a triangle. Lorenz Lindelöf found that, corresponding to any given tetrahedron is a point now known as an isogonic center, "O", at which the solid angles subtended by the faces are equal, having a common.

Tetrahedron. and counterclockwise orientations of the surface.Putting any of the four vertices in the role of "O" yields four such identities, but at most three of them are independent: If the "clockwise" sides of three of them are multiplied and the product is inferred to be equal to the product of the "counterclockwise" sides of the same three identities, and then common factors are cancelled from both sides, the result is the fourth identity.Three angles are the angles of some triangle if and only if their sum is 180° (π radians). What condition on 12 angles is necessary and sufficient for.

Tetrahedron. them to be the 12 angles of some tetrahedron? Clearly the sum of the angles of any side of the tetrahedron must be 180°. Since there are four such triangles, there are four such constraints on sums of angles, and the number of degrees of freedom is thereby reduced from 12 to 8. The four relations given by this sine law further reduce the number of degrees of freedom, from 8 down to not 4 but 5, since the fourth constraint is not independent of the first three. Thus the space of all shapes of tetrahedra is 5-dimensional.## Law of.

Tetrahedron. of the tetrahedron.With this definition, the circumcenter of a tetrahedron with vertices ,, can be formulated as matrix-vector product:formula_35In contrast to the centroid, the circumcenter may not always lay on the inside of a tetrahedron.Analogously to an obtuse triangle, the circumcenter is outside of the object for an obtuse tetrahedron.## Centroid.The tetrahedron's center of mass computes as the arithmetic mean of its four vertices, see Centroid.## Faces.The sum of the areas of any three faces is greater than the area of the fourth face.## Integer tetrahedra.There exist tetrahedra having integer-valued edge lengths, face areas and volume. These are called Heronian.

One example has one edge of 896, the opposite edge of 990 and the other four edges of 1073; two faces are isosceles triangles with areas of and the other two are isosceles with areas of , while the volume is .A tetrahedron can have integer volume and consecutive integers as edges, an example being the one with edges 6, 7, 8, 9, 10, and 11 and volume 48.## Related polyhedra and compounds.A regular tetrahedron can be seen as a triangular pyramid.A regular tetrahedron can be seen as a degenerate polyhedron, a uniform "digonal antiprism", where base polygons are.

Morchella esculenta. pale brownish cream, yellow to tan or pale brown to grayish brown. The edges of the ridges are usually lighter than the pits, and somewhat oval in outline, sometimes bluntly cone-shaped with a rounded top or more elongate. Caps are hollow, attached to the stem at the lower edge, and typically about 2 – 7 (cm) broad by 2 – 10 (cm) tall. The flesh is brittle. The stem is white to pallid or pale yellow, hollow, and straight or with a club-shaped or bulbous base. It is finely granular overall, somewhat ridged, generally about 2 – 9 (cm) long.

Morchella esculenta. by 2 – 5 (cm) thick. In age it may have brownish stains near the base. It has a passing resemblance to the common stinkhorn ("Phallus impudicus"), for which it is sometimes mistaken. Yellow morels are often found near wooded areas. Centipedes sometimes make their home inside these morels; infested morels usually have a hole in the top.## Microscopic characteristics.The spores range from white to cream to slightly yellow in deposit, although a spore print may be difficult to obtain given the shape of the fruit body. The spores are formed in asci lining the pits—the ridges are sterile. They.

Pohick Creek. Pohick Creek is a 14.0 (mi) tributary stream of the Potomac River in Fairfax County in the U.S. state of Virginia. It takes its name from the Pohick Native American tribe once prevalent in the area.Pohick Creek forms in the vicinity of Burke and flows southeast past the western edge of Fort Belvoir to empty into the tidal Pohick Bay, which itself empties, along with Accotink Bay, into Gunston Cove, an embayment of the tidal Potomac River. Pohick Creek is a popular stream for whitewater kayaking, rafting, and paddling, providing Class II and III rapids along a 5.5 (mi) stretch.

Golden-crowned sparrow. The golden-crowned sparrow (Zonotrichia atricapilla) is a large New World sparrow found in the western part of North America.## Systematics.The golden-crowned sparrow is one of five species in the genus "Zonotrichia", a group of large American sparrows. It has no subspecies. It is a sister species with, and very closely related to, the white-crowned sparrow; studies of mitochondrial DNA show the two evolved into separate species very recently in geologic time. The white-throated sparrow is a slightly more distant relative. Hybridization with both white-crowned and white-throated sparrows has been reported.Ornithologist John Latham first described the species in his book "General.

Golden-crowned sparrow. Synopsis of Birds" in 1781, but he thought it was a variety of what he called the "black-crowned bunting" and neglected to give it a scientific name. That lapse was corrected in 1789, when Johann Friedrich Gmelin assigned it the name "Emberiza atricapilla" in the 13th edition of "Systema naturae". Various authorities in the 1800s (including John James Audubon) placed it in the genus "Fringilla", but many assigned it to its current genus, "Zonotrichia", once William John Swainson had established that genus. Peter Simon Pallas described the same species in 1844 as "Zonotrichia coronata" and, for much of the 1800s,.

Golden-crowned sparrow. this was the name used by most authorities.In the bird's scientific name, the genus name "Zonotrichia" is a compound word: from Ancient Greek (, ) and (, ). The specific epithet "atricapilla" is Latin for "black-haired": () and ().## Description.Measuring 15 – 18 (cm) in length with a wingspan of 24.75 (cm) and ranging from 19.0 to 35.4 (g) in mass, the adult golden-crowned sparrow is fairly large for an American sparrow. Like all "Zonotrichia" sparrows, it has a relatively long, square-tipped tail and a slightly peaked crown. Males and females are similarly plumaged, though males average slightly larger than.

Golden-crowned sparrow. females. Other than a plain gray nape, the adult's upperparts are grayish-brown, with broad brownish-black streaks on the back and scapulars, and an unstreaked rump. Its underparts are gray, slightly paler on the belly and buffier on the flanks. Its wings and tail are brown, and it shows two white wing bars. Its legs are pale brown, and its bill is dark, with the upper mandible darker than the lower. Its iris is brown.In the breeding season, the golden-crowned sparrow has a broad yellow central crown stripe which becomes pale gray towards the back of the head.## Similar species.Although its.

Golden-crowned sparrow. distinctive crown patches allow for easy identification of the adult golden-crowned sparrow in breeding plumage, an immature or non-breeding bird might be mistaken for a white-crowned or white-throated sparrow. It is distinguished from the former by its crown pattern and dusky (rather than pale pink or yellowish) bill, and from the latter by its larger size, plain throat, and lack of a buff-colored central crown stripe. A young or non-breeding bird may also resemble a female house sparrow, but can be distinguished by its larger size, darker plumage, longer tail and (usually) some amount of dull yellow feathering on its.

Golden-crowned sparrow. forehead.## Distribution and habitat.The golden-crowned sparrow is common along the western edge of North America. It is a migratory species, breeding from north-central Alaska (including the Aleutian Islands as far west as Unimak Island) and central Yukon south to the northwestern corner of the US state of Washington, and wintering from southern coastal Alaska to northern Baja California. It has been recorded as a vagrant in Japan and Russia, and occasionally strays as far as the eastern coast of North America, from Nova Scotia to Florida. In the winter, it is generally found in brushy areas, (particularly chaparral), usually in.

Golden-crowned sparrow. dense shrubs.## Behavior.The golden-crowned sparrow spends its winters in flocks with conspecifics, but also often with other sparrow species, especially white-crowned sparrows. Flock territories typically range in size from 15 – 20 (acre). Individual birds remain with the same flock for the entire winter and return to the same wintering site each year. Studies show that the golden-crowned sparrow's black and gold head stripes are used to signal social status in wintering flocks. Such signals help to reduce the incidence of confrontation between flock mates, thereby reducing such potential costs as injuries or the unnecessary expenditure of energy. The size.

Golden-crowned sparrow. and color of a bird's crown patches are better predictors of dominance (indicating which bird will avoid confrontation with another) than are the bird's size or sex. Birds with similarly sized gold crown patches are far more likely to engage in agonistic behavior than are those showing differences, and the outcomes of such confrontations can be predicted based on the color of their black stripes. This suggests that social status in this species involves more complexity than a single signal will allow, and that the multiple color patches allow a gradient of interactions between flock mates.## Feeding.Like other "Zonotrichia" sparrows,.

Golden-crowned sparrow. the golden-crowned sparrow feeds on the ground, where it forages by pecking and scratching. It also occasionally leaps into the air after insects or gleans them from foliage. Its diet, particularly in the winter, consists primarily of plant material; items include seeds, berries, flowers and buds, as well as the occasional crawling insect. The species is an important destroyer of weed seeds on the Pacific Slope, with various ryegrasses, fescues, bromes, pigweeds, chickweeds, mulleins, filarees, common knotweed and poison oak among its known food sources. Paired birds commonly forage together, with the male following the female.The species shows two weight.

Golden-crowned sparrow. peaks each year: one in mid-winter, and a much higher one shortly before it begins its migration north in the spring. The latter elevated weight is maintained until the bird reaches its breeding grounds.## Breeding and lifespan.The breeding season runs from late May through early August. Males on the breeding ground sing throughout the day from an exposed perch. The nest is a bulky cup built by the female. Located on the ground (or occasionally on a low branch), it is made of dried plant material and lined with hair, fine grasses and feathers. The female typically lays five eggs,.

Golden-crowned sparrow. though clutches of three to five have been recorded. The eggs, which are pale green, oval and heavily spotted with reddish-brown, measure (0.65–0.67)×(0.80–0.82) mm (0.026×0.031 in). They are incubated by the female for 11–14 days. The young are altricial—born naked, blind and helpless—but fledge from the nest within 12 days. Both parents feed the young.The oldest known golden-crowned sparrow lived at least 10 years and 6 months; it was banded as an adult one winter, and recaptured nine winters later.## Voice.The song is a three-note whistle, descending in pitch. It is very distinctive, and often described as "oh-dear-me". The call.

Golden-crowned sparrow. also sounds like the words "I'm so weary", so Alaskan gold miners along the trails called this bird "Weary Willie". However, birds in the mountains of British Columbia have been reported to have a trill on the third note, rather than a clear whistle as in other populations. These songs are heard mainly in the breeding season, but also in the wintering grounds just after fall migration as well as just before they take off for spring migration. Like other "Zonotrichia" sparrows, it has a sharp, distinctive call note, which is transcribed as "tsew".## Conservation and threats.The International Union for.

Golden-crowned sparrow. Conservation of Nature lists the golden-crowned sparrow as a species of least concern. The sparrow's extremely large range and population size lift it well above the thresholds used to designate an imperiled species, and data from Christmas Bird Counts show that its numbers are stable or increasing. Throughout its range, it is protected by the Migratory Bird Treaty Act of 1918, and many of its wintering grounds are in protected areas, including national forests and national wildlife refuges.As with other flock-living passerines, the golden-crowned sparrow is prone to elevated levels of feather mites. It serves as a host for chiggers,.

Golden-crowned sparrow. chewing lice, including "Machaerilaemus maestum", and hippoboscid flies, including "Ornithoica vicina". Diseases which are known to affect it include canarypox. A number of predators prey on the golden-crowned sparrow at some point in its life cycle. These include northern and loggerhead shrikes, sharp-shinned and Cooper's hawks, northern harriers, merlins, mountain pygmy owls, western screech owls, barn owls, feral cats, and Columbian ground squirrels.
