Welch goes on to state that the "first real thermal soaring" occurred in 1930 by A. Haller and Wolf Hirth, with Hirth using a variometer in his Musterle. Frank Irving states that Arthur Kantrowitz first mentioned total energy in 1940. However, as early as 1901, Wilbur Wright wrote about thermals, "when gliding operators have attained greater.

After the variometer was invented in 1929 by Alexander Lippisch and Robert Kronfeld, the sport of gliding moved into a new realm.Variometers also became important in foot-launch hang gliding, where the open-to-air pilot hears the wind but needs the variometer to help him or her to detect regions of rising or sinking air. In early hang gliding, variometers were not needed for the short flights or flights close to ridge lift. But the variometer became key as pilots began making longer flights. The first portable variometer for use in hang gliders was the Colver.

Bursaria spinosa. Bursaria spinosa is a small tree or shrub in the family Pittosporaceae. The species occurs mainly in the eastern and southern half of Australia and not in Western Australia and the Northern Territory. Reaching 10 m (35 ft) high, it bears fragrant white flowers at any time of year but particularly in summer. A common understorey shrub of eucalyptus woodland, it colonises disturbed areas and fallow farmland. It is an important food plant for several species of butterflies and moths, particularly those of the genus "Paralucia", and native bees.## Description."Bursaria spinosa" has a variable habit, and can grow anywhere from.

Bursaria spinosa. first formally described by Antonio José Cavanilles in 1797 in his book, "Icones et Descriptiones Plantarum". It is known by many common names, including Australian blackthorn, blackthorn, Christmas bush, mock orange, native blackthorn, native box, native olive, prickly box, prickly pine, spiny box, spiny bursaria, sweet bursaria, thorn box and whitethorn. Summer flowering has given rise to the name (Tasmanian) Christmas bush in Tasmania and South Australia (not to be confused with "Prostanthera lasianthos"). Indigenous names recorded include "kurwan" in Coranderrk, Victoria, and "geapga" from Lake Hindmarsh Station."Bursaria spinosa" is highly variable in appearance and habit, as are other species.

For example, in 1893, Jules Alexandre Daveau, in Désiré Georges Jean Marie Bois's "Dictionnaire d'Horticulture", described varieties "inermis" (meaning "without spines") and "macrophylla" ("large leaves"), but var. "macrophylla" was a nomen illegitimum because it had already been used by William Jackson Hooker in 1834.A 1999 revision of the genus recognised only two subspecies and the names are accepted by the Australian Plant Census: "Bursaria spinosa" subsp. "lasiophylla" has shorter, wider leaves and smaller flowers than the autonym, only reaches a height of 5 (m), replaces the.

Bursaria spinosa. autonym on heavier clay soils, and occurs in New South Wales, Victoria and South Australia; "Bursaria spinosa" subsp. "spinosa" is a shrub or small tree to 5–10 (m) and is widely distributed across eastern Australia, including Queensland and Tasmania. Subspecies "lasiophylla" had been known as "Bursaria lasiophylla", first formally described in 1978 by Eleanor Marion Bennett, but reduced to a subspecies by Lindy Cayzer, Michael Crisp and Ian Telford in 1999.## Distribution and habitat."Bursaria spinosa" is widespread and common in the understorey of eucalypt woodland in all states of Australia, apart from Western Australia and the Northern Territory. In New.

Bursaria spinosa. South Wales, "B. spinosa" grows in dry to wet forest in all but the most arid parts of the state, and is sometimes a weed on cleared land. In the Sydney region, it grows on clay- and shale-based soils, as an understory plant in association with grey box ("Eucalyptus moluccana") and forest red gum ("E. tereticornis") as well as the grass "Themeda australis". It can form thickets on ungrazed farmland. In Victoria, the species is widespread and common throughout the state, except for the far north west, in heavier soils and in alpine areas, in South Australia it is widespread.

The larvae of the jewel beetle species "Astraeus crassus" live in tunnels in dead and dying branches. Caterpillars which feed on "Bursaria spinosa" include "Proselena annosana", two-ribbed arctiid ("Palaeosia bicosta") and bark looper moth ("Ectropis subtinctaria"), while those of the clouded footman ("Anestia ombrophanes") graze on algae and lichens which grow on the branches.The bright copper ("Paralucia aurifera") and ant species "Anonychomyrma nitidiceps" form a complex symbiotic relationship on "Bursaria spinosa". Butterflies lay their eggs on the underside of the leaves, and the caterpillars feed on the leaves.

Het Steen. Het Steen is a medieval fortress in the old city centre of Antwerp, Belgium, one of Europe's biggest ports. The surviving structure was built between 1200 and 1225 as a gateway to a larger castle of the Dukes of Brabant which was demolished in the 19th century. As the first stone fortress of Antwerp, Het Steen is Antwerp's oldest building and used to be its oldest urban centre. The words "Het Steen", are dutch for The Rock.The first documented mention of Antwerp Castle dates back to the 12th century. However, there was a castle here as early as the Carolingian.

The Margraviate of Antwerp came into being around 974. The Duchy of Lower Lotharingia was part of the Holy Roman Empire, while on the opposite bank of the Scheldt lay the county of Flanders, which was subordinate to the king of France. From 1076 to 1100 Godfrey of Bouillon was the Margrave of Antwerp. Godfrey I, Count of Louvain, received the duchy in 1106. His great-grandson was Henry I, Duke of Brabant who.

The rebuilding led to its being known first as "'s Heeren Steen" (the King's stone castle), and later simply as "Het Steen" (the stone castle). The Dutch word "steen" means "stone", and used to be used for "fortress" or "palace", as in the "Gravensteen" in Ghent, Belgium.The fortress made it possible to control the access to the Scheldt, the river on whose bank it stands. It was used as a prison between 1303.

The largest part of the fortress, including dozens of historic houses and the oldest church of the city, was demolished in the 19th century when the quays were straightened to stop the silting up of the Scheldt. The remaining building, heavily changed, contains a shipping museum, with some old canal barges displayed on the quay outside.In 1890 Het Steen became the museum of archeology and in 1952 an annex was added to house the museum of Antwerp maritime history, which in 2011 moved to the nearby Museum Aan de Stroom.

Emirates Stadium. The Emirates Stadium (known as Ashburton Grove prior to sponsorship, and as Arsenal Stadium for UEFA competitions) is a football stadium in Holloway, London, England. It is the home of Arsenal FC, since its completion in 2006. It has a current seated capacity of 60,704, making it the fifth-largest football stadium in England. In 1997, Arsenal explored the possibility of relocating to a new stadium, having been denied planning permission by Islington Council to expand its home stadium, Highbury. After considering various options (including purchasing Wembley Stadium), the club bought an industrial and waste disposal estate in Ashburton Grove in.

A year later, they received the council's approval to build a stadium on the site; manager Arsène Wenger described this as the "biggest decision in Arsenal's history" since the board appointed Herbert Chapman. Relocation began in 2002, but financial difficulties delayed work until February 2004. Emirates was later announced as the main sponsor for the stadium. The entire stadium project was completed in 2006 at a cost of £390 million. The club's former stadium was redeveloped as Highbury Square, an apartment complex.The stadium has undergone a process of "Arsenalisation" since 2009 with the aim of restoring visible links to.

The Football Association (FA) and the English National Stadium Trust opposed Arsenal's offer, claiming it harmed England's bid for the 2006 FIFA World Cup, which FIFA itself denied. In April 1998, Arsenal withdrew its bid and Wembley was purchased by the English National Stadium Trust. The club however was given permission to host its UEFA Champions League home ties at Wembley for the 1998–99 and 1999–2000 seasons. Although Arsenal's time in the competition was brief, twice exiting the group stages, the club set its record home attendance (73,707 against.

The stadium later became issue in the local elections in May 2006. The Metropolitan Police restricted supporters' coaches to being parked in the nearby Sobel Sports Centre rather than in the underground stadium car park, and restricted access to 14 streets on match days. These police restrictions were conditions of the stadiums' health and safety certificate which the stadium requires to operate and open.

Emirates Stadium. The road closures were passed at a council meeting in July 2005.## Finance and naming.Securing finance for the stadium project proved a challenge as Arsenal received no public subsidy from the government. Whereas Wenger claimed French clubs "pay nothing at all for their stadium, nothing at all for their maintenance," and "Bayern Munich paid one euro for their ground," Arsenal were required to buy the site outright in one of London's most expensive areas. The club therefore sought other ways of generating income, such as making a profit on player trading. Arsenal recouped over £50 million from transfers involving Nicolas.

Baleen whale. Baleen whales (systematic name Mysticeti), also known as whalebone whales, are a parvorder of carnivorous marine mammals of the infraorder Cetacea (whales, dolphins and porpoises) which use keratinaceous baleen plates (or "whalebone") in their mouths to sieve planktonic creatures from the water. Mysticeti comprises the families Balaenidae (right and bowhead whales), Balaenopteridae (rorquals and the gray whale), and Cetotheriidae (the pygmy right whale). There are currently 16 species of baleen whales. While cetaceans were historically thought to have descended from mesonychids, molecular evidence instead supports them as a clade of even-toed ungulates (Artiodactyla). Baleen whales split from toothed whales (Odontoceti).

Baleen whale. around 34 million years ago.Baleen whales range in size from the 6 (m) and 3000 (kg) pygmy right whale to the 31 (m) and 190 (MT) blue whale, the largest known animal to have ever existed. They are sexually dimorphic. Baleen whales can have streamlined or large bodies, depending on the feeding behavior, and two limbs that are modified into flippers. The fin whale is the fastest baleen whale, recorded swimming at 10 (m/s). Baleen whales use their baleen plates to filter out food from the water by either lunge-feeding or skim-feeding. Baleen whales have fused neck vertebrae, and are.

Baleen whale. unable to turn their heads at all. Baleen whales have two blowholes. Some species are well adapted for diving to great depths. They have a layer of fat, or blubber, under the skin to keep warm in the cold water.Although baleen whales are widespread, most species prefer the colder waters of the Arctic and Antarctic. Gray whales are specialized for feeding on bottom-dwelling crustaceans. Rorquals are specialized at lunge-feeding, and have a streamlined body to reduce drag while accelerating. Right whales skim-feed, meaning they use their enlarged head to effectively take in a large amount of water and sieve the.

Baleen whale. slow-moving prey. Males typically mate with more than one female (polygyny), although the degree of polygyny varies with the species. Male strategies for reproductive success vary between performing ritual displays (whale song) or lek mating. Calves are typically born in the winter and spring months and females bear all the responsibility for raising them. Mothers fast for a relatively long period of time over the period of migration, which varies between species. Baleen whales produce a number of infrasonic vocalizations, notably the songs of the humpback whale.The meat, blubber, baleen, and oil of baleen whales have traditionally been used by.

Baleen whale. the indigenous peoples of the Arctic. Once relentlessly hunted by commercial industries for these products, cetaceans are now protected by international law. These protections have allowed their numbers to recover. However, the North Atlantic right whale is ranked endangered by the International Union for Conservation of Nature. Besides hunting, baleen whales also face threats from marine pollution and ocean acidification. It has been speculated that man-made sonar results in strandings. They have rarely been kept in captivity, and this has only been attempted with juveniles or members of one of the smallest species.## Taxonomy.Baleen whales are cetaceans classified under the.

Balaenids are distinguished by their enlarged head and thick blubber, while rorquals and gray whales generally have a flat head, long throat pleats, and are more streamlined than Balaenids. Rorquals also tend to be longer than the latter. Cetaceans (whales, dolphins, and porpoises) and artiodactyls are now classified under the order Cetartiodactyla, often still referred to as Artiodactyla (given that the cetaceans are deeply nested with the artiodactyls). The closest living relatives to baleen whales are toothed whales.

Baleen whale. both from the infraorder Cetacea.## Classification.Balaenidae consists of two genera: "Eubalaena" (right whales) and "Balaena" (the bowhead whale, "B. mysticetus"). Balaenidae was thought to have consisted of only one genus until studies done through the early 2000s reported that bowhead whales and right whales are morphologically (different skull shape) and phylogenically different. According to a study done by H. C. Rosenbaum (of the American Museum of Natural History) and colleagues, the North Pacific ("E. japonica") and Southern right ("E. australis") whales are more closely related to each other than to the North Atlantic right whale ("E. glacialis").Cetotheriidae consists of only.

Baleen whale. one living member: the pygmy right whale ("Caperea marginata"). The first descriptions date back to the 1840s of bones and baleen plates resembling a smaller version of the right whale, and was named "Balaena marginata". In 1864, it was moved into the genus "Caperea" after a skull of another specimen was discovered. Six years later, the pygmy right whale was classified under the family Neobalaenidae. Despite its name, the pygmy right whale is more genetically similar to rorquals and gray whales than to right whales. A study published in 2012, based on bone structure, moved the pygmy right whale from.

Baleen whale. and colleagues suggested that, based on phylogenic criteria, there are four extant genera of rorquals. They recommend that the genus "Balaenoptera" be limited to the fin whale, have minke whales fall under the genus "Pterobalaena", and have "Rorqualus" contain the Sei whale, Bryde's whale, Eden's whale (and by extension Rice's whale), the blue whale, and Omura's whale. The gray whale was formerly classified in its own family. The two populations, one in the Sea of Okhotsk and Sea of Japan and the other in eastern Pacific are thought to be genetically and physiologically dissimilar. However, there is some discussion as.

Baleen whale. although obviously more appropriate and occasionally used in the past, has been superseded by "Mysticeti" (junior synonym).Mysticetes are also known as baleen whales because of the presence of baleen. These animals rely on their baleen plates to sieve plankton and other small organisms from the water. The term "baleen" (Middle English "baleyn, ballayne, ballien, bellane", etc.) is an archaic word for "whale", which came from Old French "baleine", derived from the Latin word "balæna", derived itself from the Ancient Greek "φάλλαινα" ("phállaina)".Right whales got their name because of whalers preferring them over other species; they were essentially the "right whale.

Baleen whale. streamlined body. They have callosities, unlike other whales, with the exception of the bowhead whale. Rorquals have a higher proportion of muscle tissue and tend to be negatively buoyant, whereas right whales have a higher proportion of blubber and are positively buoyant. Gray whales are easily distinguished from the other rorquals by their sleet-gray color, dorsal ridges (knuckles on the back), and their gray-white scars left from parasites. As with the other rorquals, their throat pleats increase the capacity of their throats, allowing them to filter larger volumes of water at once. Gray whales are bottom-feeders, meaning they sift through.

Baleen whale. sand to get their food. They usually turn on their sides, scoop up sediment into their mouths and filter out benthic creatures like amphipods, which leave noticeable marks on their heads. The pygmy right whale is easily confused with minke whales because of their similar characteristics, such as their small size, dark gray tops, light gray bottoms, and light eye patches.## Evolutionary history.Molecular phylogeny suggests Mysticeti split from Odontoceti (toothed whales) between 26 and 17 million years ago between the late Oligocene or middle Miocene, but the earliest Mysticeti fossils date to at least 34 million years ago. Their evolutionary.

Baleen whale. link to archaic toothed cetaceans (Archaeoceti) remained unknown until the extinct "Janjucetus hunderi" was discovered in the early 1990s in Victoria, Australia. While, unlike a modern baleen whale, "Janjucetus" lacked baleen in its jaw, the anatomy shows sufficient similarity to baleen whales. It appears to have had very limited apparent biosonar capabilities. Its jaw contained teeth, with incisors and canines built for stabbing and molars and premolars built for tearing. These early mysticetes were exceedingly small compared to modern baleen whales, with species like "Mammalodon" measuring no greater than 10 (ft). It is thought that their size increased with their.

Baleen whale. However, the 2018 discovery of the toothless "Maiabalaena" indicates some lineages evolved toothlessness before baleen."Mystacodon selenensis" is the earliest mysticete, dating back to 37 to 33 million years ago (mya) in the Late Eocene, and, like other early toothed mysticetes, or "archaeomysticetes", "M. selenensis" had heterodont dentition used for suction feeding. Archaeomysticetes from the Oligocene are the Mammalodontidae ("Mammalodon" and "Janjucetus") from Australia. They were small with shortened rostra, and a primitive dental formula (). In baleen whales, it is thought that enlarged mouths adapted for suction feeding evolved before specializations for bulk filter feeding. In the toothed Oligocene mammalodontid.

Baleen whale. "Janjucetus", the symphysis is short and the mouth enlarged, the rostrum is wide, and the edges of the maxillae are thin, indicating an adaptation for suction feeding. The aetiocetid "Chonecetus" still had teeth, but the presence of a groove on the interior side of each mandible indicates the symphysis was elastic, which would have enabled rotation of each mandible, an initial adaptation for bulk feeding like in modern mysticetes.The first toothless ancestors of baleen whales appeared before the first radiation in the late Oligocene. "Eomysticetus" and others like it showed no evidence in the skull of echolocation abilities, suggesting they.

Baleen whale. mainly relied on their eyesight for navigation. The eomysticetes had long, flat rostra that lacked teeth and had blowholes located halfway up the dorsal side of the snout. Though the palate is not well-preserved in these specimens, they are thought to have had baleen and been filter feeders. Miocene baleen whales were preyed upon by larger predators like killer sperm whales and megalodon.The lineages of rorquals and right whales split almost 20 mya. It is unknown where this occurred, but it is generally believed that they, like their descendants, followed plankton migrations. These primitive baleen whales had lost their dentition.

Baleen whale. in favor of baleen, and are believed to have lived on a specialized benthic, plankton, or copepod diet like modern baleen whales. Baleen whales experienced their first radiation in the mid-Miocene. It is thought this radiation was caused by global climate change and major tectonic activity when Antarctica and Australia separated from each other, creating the Antarctic Circumpolar Current. Balaenopterids grew bigger during this time, with species like "Balaenoptera sibbaldina" perhaps rivaling the blue whale in terms of size, though other studies disagree that any baleen whale grew that large in the Miocene.The increase in size is likely due to.

Baleen whale. climate change which caused seasonally shifting accumulations of plankton in various parts of the world, necessitating travel over long distances, as well as the ability to feed on large baitballs to make such trips worthwhile. A 2017 analysis of body size based on data from the fossil record and modern baleen whales indicates that the evolution of gigantism in baleen whales occurred rather recently, within the last 3 million years. Before 4.5 million years ago, few baleen whales exceeded 10 (m) in length; the two largest Miocene species were less than 13 (m) in length. The initial evolution of baleen.

Baleen whale. and filter feeding long preceded the evolution of gigantic body size, indicating the evolution of novel feeding mechanisms did not cause the evolution of gigantism. The formation of the Antarctic circumpolar current and its effects on global climate patterns is excluded as being causal for the same reason. Gigantism also was preceded by divergence of different mysticete lineages, meaning multiple lineages arrived at large size independently. It is possible the Plio-Pleistocene increase in seasonally intense upwellings, causing high-prey-density zones, led to gigantism.## Anatomy.## Motion.When swimming, baleen whales rely on their flippers for locomotion in a wing-like manner similar to penguins.

Baleen whale. and sea turtles. Flipper movement is continuous. While doing this, baleen whales use their tail fluke to propel themselves forward through vertical motion while using their flippers for steering, much like an otter. Some species leap out of the water, which may allow them to travel faster. Because of their great size, right whales are not flexible or agile like dolphins, and none can move their neck because of the fused cervical vertebrae; this sacrifices speed for stability in the water. The hind legs are enclosed inside the body, and are thought to be vestigial organs. However, a 2014 study.

Baleen whale. suggests that the pelvic bone serves as support for whale genitalia.Rorquals, needing to build speed to feed, have several adaptions for reducing drag, including a streamlined body; a small dorsal fin, relative to its size; and lack of external ears or long hair. The fin whale is the fastest among baleen whales, having been recorded travelling as fast as 10 (m/s), and sustaining a speed of 2.5 (m/s) for an extended period. While feeding, the rorqual jaw expands to a volume that can be bigger than the whale itself; to do this, the mouth inflates. The inflation of the mouth.

Baleen whale. causes the cavum ventrale, the throat pleats on the underside stretching to the navel, to expand, increasing the amount of water that the mouth can store. The mandible is connected to the skull by dense fibers and cartilage (fibrocartilage), allowing the jaw to swing open at almost a 90° angle. The mandibular symphysis is also fibrocartilaginous, allowing the jaw to bend which lets in more water. To prevent stretching the mouth too far, rorquals have a sensory organ located in the middle of the jaw to regulate these functions.## External anatomy.Baleen whales have two flippers on the front, near the.

Baleen whale. head. Like all mammals, baleen whales breathe air and must surface periodically to do so. Their nostrils, or blowholes, are situated at the top of the cranium. Baleen whales have two blowholes, as opposed to toothed whales which have one. These paired blowholes are longitudinal slits that converge anteriorly and widen posteriorly, which causes a V-shaped blow. They are surrounded by a fleshy ridge that keeps water away while the whale breathes. The septum that separates the blowholes has two plugs attached to it, making the blowholes water-tight while the whale dives.Like other mammals, the skin of baleen whales has.

Baleen whale. an epidermis, a dermis, a hypodermis, and connective tissue. The epidermis, the pigmented layer, is 5 (mm) thick, along with connective tissue. The epidermis itself is only 1 (mm) thick. The dermis, the layer underneath the epidermis, is also thin. The hypodermis, containing blubber, is the thickest part of the skin and functions as a means to conserve heat. Right whales have the thickest hypodermis of any cetacean, averaging 20 (in), though, as in all whales, it is thinner around openings (such as the blowhole) and limbs. Blubber may also be used to store energy during times of fasting. The.

Baleen whale. connective tissue between the hypodermis and muscles allows only limited movement to occur between them. Unlike toothed whales, baleen whales have small hairs on the top of their head, stretching from the tip of the rostrum to the blowhole, and, in right whales, on the chin. Like other marine mammals, they lack sebaceous and sweat glands.The baleen of baleen whales are keratinous plates. They are made of a calcified, hard α-keratin material, a fiber-reinforced structure made of intermediate filaments (proteins). The degree of calcification varies between species, with the sei whale having 14.5% hydroxyapatite, a mineral that coats teeth and.

Baleen whale. bones, whereas minke whales have 1–4% hydroxyapatite. In most mammals, keratin structures, such as wool, air-dry, but aquatic whales rely on calcium salts to form on the plates to stiffen them. Baleen plates are attached to the upper jaw and are absent in the mid-jaw, forming two separate combs of baleen. The plates decrease in size as they go further back into the jaw; the largest ones are called the "main baleen plates" and the smallest ones are called the "accessory plates". Accessory plates taper off into small hairs.Unlike other whales (and most other mammals), the females are larger than.

Baleen whale. the males. Sexual dimorphism is usually reversed, with the males being larger, but the females of all baleen whales are usually five percent larger than males. Sexual dimorphism is also displayed through whale song, notably in humpback whales where the males of the species sing elaborate songs. Male right whales have bigger callosities than female right whales. The males are generally more scarred than females which is thought to be because of aggression during mating season.## Internal systems.The unique lungs of baleen whales are built to collapse under the pressure instead of resisting the pressure which would damage the lungs,.

Baleen whale. enabling some, like the fin whale, to dive to a depth of -1540 (ft). The whale lungs are very efficient at extracting oxygen from the air, usually 80%, whereas humans only extract 20% of oxygen from inhaled air. Lung volume is relatively low compared to terrestrial mammals because of the inability of the respiratory tract to hold gas while diving. Doing so may cause serious complications such as embolism. Unlike other mammals, the lungs of baleen whales lack lobes and are more sacculated. Like in humans, the left lung is smaller than the right to make room for the heart.

Baleen whale. To conserve oxygen, blood is rerouted from pressure-tolerant-tissue to internal organs, and they have a high concentration of myoglobin which allows them to hold their breath longer.The heart of baleen whales functions similarly to other mammals, with the major difference being the size. The heart can reach 1000 (lbs), but is still proportional to the whale's size. The muscular wall of the ventricle, which is responsible for pumping blood out of the heart, can be 3 to 5 (in) thick. The aorta, an artery, can be .75 (in) thick. Their resting heart rate is 60 to 140 beats per minute.

Baleen whale. (bpm), as opposed to the 60 to 100 bpm in humans. When diving, their heart rate will drop to 4 to 15 bpm to conserve oxygen. Like toothed whales, they have a dense network of blood vessels (rete mirabile) which prevents heat-loss. Like in most mammals, heat is lost in their extremities, so, in baleen whales, warm blood in the arteries is surrounded by veins to prevent heat loss during transport. As well as this, heat inevitably given off by the arteries warms blood in the surrounding veins as it travels back into the core. This is otherwise known as.

Baleen whale. countercurrent exchange. To counteract overheating while in warmer waters, baleen whales reroute blood to the skin to accelerate heat-loss. They have the largest blood corpuscles (red and white blood cells) of any mammal, measuring 4.1e-4 (in) in diameter, as opposed to human's 2.8e-4 (in) blood corpuscles.When sieved from the water, food is swallowed and travels through the esophagus where it enters a three-chambered-stomach. The first compartment is known as the fore-stomach; this is where food gets ground up into an acidic liquid, which is then squirted into the main stomach. Like in humans, the food is mixed with hydrochloric acid.

Baleen whale. and protein-digesting enzymes. Then, the partly digested food is moved into the third stomach, where it meets fat-digesting enzymes, and is then mixed with an alkaline liquid to neutralize the acid from the fore-stomach to prevent damage to the intestinal tract. Their intestinal tract is highly adapted to absorb the most nutrients from food; the walls are folded and contain copious blood vessels, allowing for a greater surface area over which digested food and water can be absorbed. Baleen whales get the water they need from their food; however, the salt content of most of their prey (invertebrates) is similar.

Baleen whale. to that of seawater, whereas the salt content of a whale's blood is considerably lower (three times lower) than that of seawater. The whale kidney is adapted to excreting excess salt; however, while producing urine more concentrated than seawater, it wastes a lot of water which must be replaced.Baleen whales have a relatively small brain compared to their body mass. Like other mammals, their brain has a large, folded cerebrum, the part of the brain responsible for memory and processing sensory information. Their cerebrum only makes up about 68% of their brain's weight, as opposed to human's 83%. The cerebellum,.

Baleen whale. the part of the brain responsible for balance and coordination, makes up 18% of their brain's weight, compared to 10% in humans, which is probably due to the great degree of control necessary for constantly swimming. Necropsies on the brains of gray whales revealed iron oxide particles, which may allow them to find magnetic north like a compass.Unlike most animals, whales are conscious breathers. All mammals sleep, but whales cannot afford to become unconscious for long because they may drown. They are believed to exhibit unihemispheric slow-wave sleep, in which they sleep with half of the brain while the other.

Baleen whale. half remains active. This behavior was only documented in toothed whales until footage of a humpback whale sleeping (vertically) was shot in 2014.It is largely unknown how baleen whales produce sound because of the lack of a melon and vocal cords. In a 2007 study, it was discovered that the larynx had U-shaped folds which are thought to be similar to vocal cords. They are positioned parallel to air flow, as opposed to the perpendicular vocal cords of terrestrial mammals. These may control air flow and cause vibrations. The walls of the larynx are able to contract which may generate.

Baleen whale. sound with support from the arytenoid cartilages. The muscles surrounding the larynx may expel air rapidly or maintain a constant volume while diving.## Senses.The eyes of baleen whales are relatively small for their size and are positioned near the end of the mouth. This is probably because they feed on slow or immobile prey, combined with the fact that most sunlight does not pass 30 (ft), and hence they do not need acute vision. A whale's eye is adapted for seeing both in the euphotic and aphotic zones by increasing or decreasing the pupil's size to prevent damage to the.

Baleen whale. eye. As opposed to land mammals which have a flattened lens, whales have a spherical lens. The retina is surrounded by a reflective layer of cells (tapetum lucidum), which bounces light back at the retina, enhancing eyesight in dark areas. However, light is bent more near the surface of the eye when in air as opposed to water; consequently, they can see much better in the air than in the water. The eyeballs are protected by a thick outer layer to prevent abrasions and an oily fluid (instead of tears) on the surface of the eye. Baleen whales appear to.

Baleen whale. have limited color vision, as they lack S-cones.The mysticete ear is adapted for hearing underwater, where it can hear sound frequencies as low as 7 Hz and as high as 22 kHz, distinct from odontocetes whose hearing is optimized for ultrasonic frequencies. It is largely unknown how sound is received by baleen whales. Unlike in toothed whales, sound does not pass through the lower jaw. The auditory meatus is blocked by connective tissue and an ear plug, which connects to the eardrum. The inner-ear bones are contained in the tympanic bulla, a bony capsule. However, this is attached to the.

Baleen whale. skull, suggesting that vibrations passing through the bone is important. Sinuses may reflect vibrations towards the cochlea. It is known that when the fluid inside the cochlea is disturbed by vibrations, it triggers sensory hairs which send electrical current to the brain, where vibrations are processed into sound.Baleen whales have a small, yet functional, vomeronasal organ. This allows baleen whales to detect chemicals and pheromones released by their prey. It is thought that 'tasting' the water is important for finding prey and tracking down other whales. They are believed to have an impaired sense of smell due to the lack.

Baleen whale. of the olfactory bulb, but they do have an olfactory tract. Baleen whales have few if any taste buds, suggesting they have lost their sense of taste. They do retain salt-receptor taste-buds suggesting that they can taste saltiness.## Behavior.## Migration.Most species of baleen whale migrate long distances from high latitude waters during spring and summer months to more tropical waters during winter months. This migration cycle is repeated annually. The gray whale has the longest recorded migration of any mammal, with one traveling 14,000 (mi) from the Sea of Okhotsk to the Baja Peninsula.It is thought that plankton blooms dictate.

Baleen whale. where whales migrate. Many baleen whales feed on the massive plankton blooms that occur in the cold, nutrient-rich waters of polar regions during the sunny spring and summer months. Baleen whales generally then migrate to calving grounds in tropical waters during the winter months when plankton populations are low. Migration is hypothesized to benefit calves in a number of ways. Newborns, born with underdeveloped blubber, would likely otherwise be killed by the cold polar temperatures. Migration to warmer waters may also reduce the risk of calves being predated on by killer whales.Migratory movements may also reflect seasonally shifting patterns of.

Baleen whale. productivity. California blue whales are hypothesized to migrate between dense patches of prey, moving from central California in the summer and fall, to the Gulf of California in the winter, to the central Baja California Pacific coast in spring.## Foraging.All modern mysticetes are obligate filter feeders, using their baleen to strain small prey items (including small fish, krill, copepods, and zooplankton) from seawater. Despite their carnivorous diet, a 2015 study revealed they house gut flora similar to that of terrestrial herbivores. Different kinds of prey are found in different abundances depending on location, and each type of whale is adapted.

Baleen whale. to a specialized way of foraging.There are two types of feeding behaviors: skim-feeding and lunge-feeding, but some species do both depending on the type and amount of food. Lunge-feeders feed primarily on euphausiids (krill), though some lunge feeders also prey on schools of fish. Skim-feeders, like bowhead whales, feed upon primarily smaller plankton such as copepods. They feed alone or in small groups. Baleen whales get the water they need from their food, and their kidneys excrete excess salt.The lunge-feeders are the rorquals. To feed, lunge-feeders expand the volume of their jaw to a volume bigger than the original volume.

Baleen whale. skim-feeding due to the acceleration and deceleration required.The skim-feeders are right whales, gray whales, pygmy right whales, and sei whales (which also lunge feed). To feed, skim-feeders swim with an open mouth, filling it with water and prey. Prey must occur in sufficient numbers to trigger the whale's interest, be within a certain size range so that the baleen plates can filter it, and be slow enough so that it cannot escape. The "skimming" may take place on the surface, underwater, or even at the ocean's bottom, indicated by mud occasionally observed on right whales' bodies. Gray whales feed primarily.

Baleen whale. on the ocean's bottom, feeding on benthic creatures.Foraging efficiency for both lunge feeding and continuous ram filter feeding is highly dependent upon prey density. The efficiency of a blue whale lunge is approximately 30 times higher at krill densities of 4.5 (kg/m3) than at low krill densities of 0.15 (kg/m3). Baleen whale have been observed seeking out highly specific areas within the local environment in order to forage at the highest density prey aggregations.## Predation and parasitism.Baleen whales, primarily juveniles and calves, are preyed on by killer whales. It is thought that annual whale migration occurs to protect the calves.

Baleen whale. from the killer whales. There have also been reports of a pod of killer whales attacking and killing an adult bowhead whale, by holding down its flippers, covering the blowhole, and ramming and biting until death. Generally, a mother and calf pair, when faced with the threat of a killer whale pod, will either fight or flee. Fleeing only occurs in species that can swim away quickly, the rorquals. Slower whales must fight the pod alone or with a small family group. There has been one report of a shark attacking and killing a whale calf. This occurred in 2014.

Baleen whale. during the sardine run when a shiver of dusky sharks attacked a humpback whale calf. Usually, the only shark that will attack a whale is the cookie cutter shark, which leaves a small, non-fatal bite mark.Many parasites and epibiotics latch onto whales, notably whale lice and whale barnacles. Almost all species of whale lice are specialized towards a certain species of whale, and there can be more than one species per whale. Whale lice eat dead skin, resulting in minor wounds in the skin. Whale louse infestations are especially evident in right whales, where colonies propagate on their callosities. Though.

Baleen whale. not a parasite, whale barnacles latch onto the skin of a whale during their larval stage. However, in doing so it does not harm nor benefit the whale, so their relationship is often labeled as an example of commensalism. Some baleen whales will deliberately rub themselves on substrate to dislodge parasites. Some species of barnacle, such as "Conchoderma auritum" and whale barnacles, attach to the baleen plates, though this seldom occurs. A species of copepod, "Balaenophilus unisetus", inhabits baleen plates of whales. A species of Antarctic diatom, "Cocconeis ceticola", forms a film on the skin, which takes a month to.

Baleen whale. develop; this film causes minor damage to the skin. They are also plagued by internal parasites such as stomach worms, cestodes, nematodes, liver flukes, and acanthocephalans.## Reproduction and development.Before reaching adulthood, baleen whales grow at an extraordinary rate. In the blue whale, the largest species, the fetus grows by some 100 (kg) per day just before delivery, and by 80 (kg) per day during suckling. Before weaning, the calf increases its body weight by 17 (tonnes) and grows from 7 to 8 (m) at birth to 13 to 16 (m) long. When it reaches sexual maturity after 5–10 years, it.

Baleen whale. until it has reached about 5 to 5.5 (m) after 6–7 months. Unusual for a baleen whale, female minkes (and humpbacks) can become pregnant immediately after giving birth; in most species, there is a two-to-three-year calving period. In right whales, the calving interval is usually three years. They grow very rapidly during their first year, after which they hardly increase in size for several years. They reach sexual maturity when 13 to 14 (m) long. Baleen whales are K-strategists, meaning they raise one calf at a time, have a long life-expectancy, and a low infant mortality rate. Some 19th century.

Baleen whale. harpoons found in harvested bowheads indicate this species can live more than 100 years. Baleen whales are promiscuous, with none showing pair bonds. They are polygynous, in that a male may mate with more than one female. The scars on male whales suggest they fight for the right to mate with females during breeding season, somewhat similar to lek mating.Baleen whales have fibroelastic (connective tissue) penises, similar to those of artiodactyls. The tip of the penis, which tapers toward the end, is called the "pars intrapraeputialis" or "terminal cone". The blue whale has the largest penis of any organism on.

Baleen whale. the planet, typically measuring 8 – 10 (ft). Accurate measurements of the blue whale are difficult to take because the whale's erect length can only be observed during mating. The penis on a right whale can be up to 2.7 (m) – the testes, at up to 2 (m) in length, 78 (cm) in diameter, and weighing up to 525 (lbs), are also the largest of any animal on Earth.## Whale song.All baleen whales use sound for communication and are known to "sing", especially during the breeding season. Blue whales produce the loudest sustained sounds of any animals: their low-frequency.

Baleen whale. whales are hard to study because of their immense size. Intelligence tests such as the mirror test cannot be done because their bulk and lack of body language make a reaction impossible to be definitive. However, studies on the brains of humpback whales revealed spindle cells, which, in humans, control theory of mind. Because of this, it is thought that baleen whales, or at least humpback whales, have consciousness.## Relationship with humans.## History of whaling.Whaling by humans has existed since the Stone Age. Ancient whalers used harpoons to spear the bigger animals from boats out at sea. People from Norway.

Baleen whale. started hunting whales around 4,000 years ago, and people from Japan began hunting whales in the Pacific at least as early as that. Whales are typically hunted for their meat and blubber by aboriginal groups; they used baleen for baskets or roofing, and made tools and masks out of bones. The Inuit hunt whales in the Arctic Ocean. The Basques started whaling as early as the 11th century, sailing as far as Newfoundland in the 16th century in search of right whales. 18th and 19th century whalers hunted down whales mainly for their oil, which was used as lamp fuel.

Baleen whale. and a lubricant, and baleen (or whalebone), which was used for items such as corsets and skirt hoops. The most successful whaling nations at this time were the Netherlands, Japan, and the United States.Commercial whaling was historically important as an industry well throughout the 19th and 20th centuries. Whaling was at that time a sizable European industry with ships from Britain, France, Spain, Denmark, the Netherlands, and Germany, sometimes collaborating to hunt whales in the Arctic. By the early 1790s, whalers, namely the British (Australian) and Americans, started to focus efforts in the South Pacific; in the mid-1900s, over 50,000.

Baleen whale. humpback whale were taken from the South Pacific. At its height in the 1880s, U.S. profits turned to USD10,000,000, equivalent to US$225,000,000 today. Commonly exploited species included arctic whales such as the gray whale, right whale, and bowhead whale because they were close to the main whaling ports, like New Bedford. After those stocks were depleted, rorquals in the South Pacific were targeted by nearly all whaling organizations; however, they often out-swam whaling vessels. Whaling rorquals was not effective until the harpoon cannon was invented in the late 1860s. Whaling basically stopped when stocks of all species were depleted to.

Baleen whale. individuals left)—are considered critically endangered. Three more are classified as endangered (the North Pacific right whale, the blue whale, and the sei whale), one as vulnerable (the fin whale), one as near-threatened (Antarctic minke whale), and one as data deficient (Omura's whale). Species that live in polar habitats are vulnerable to the effects of ongoing climate change, particularly declines in sea ice, as well as ocean acidification.The whale-watching industry and anti-whaling advocates argue that whaling catches "friendly" whales that are curious about boats, as these whales are the easiest to catch. This analysis claims that once the economic benefits of.

Baleen whale. hotels, restaurants and other tourist amenities are considered, hunting whales is a net economic loss. This argument is particularly contentious in Iceland, as it has among the most-developed whale-watching operations in the world and the hunting of minke whales resumed in August 2003. Brazil, Argentina and South Africa argue that whale watching is a growing billion-dollar industry that provides more revenue than commercial whaling would provide. Peru, Uruguay, Australia, and New Zealand also support proposals to permanently forbid whaling south of the Equator, as Solor (an island of Indonesia) is the only place of the Southern Hemisphere that takes whales.

Baleen whale. Anti-whaling groups, such as the International Fund for Animal Welfare (IFAW), claim that countries which support a pro-whaling stance are damaging their economies by driving away anti-whaling tourists.Commercial whaling was historically important for the world economy. All species were exploited, and as one type's stock depleted, another type was targeted. The scale of whale harvesting decreased substantially through the 1960s as all whale stocks had been depleted, and practically stopped in 1988 after the International Whaling Commission placed a moratorium which banned whaling for commercial use. Several species that were commercially exploited have rebounded in numbers; for example, gray whales.

Baleen whale. consists of only ten individuals, making the eastern stock functionally extinct.Baleen whales continue to be harvested. Only three nations take whales: Iceland, Norway, and Japan. All these nations are part of the IWC, with Norway and Iceland rejecting the moratorium and continuing commercial whaling. Japan, being part of the IWC, whales under the Scientific Permit stated in Article VIII in the Convention for the Regulation of Whaling, which allows the taking of whales for scientific research. Japan has had two main research programs: the Joint Aquatic Resources Permit Application (JARPA) and the Japanese Research Program in the North (JARPN). JARPN.

Baleen whale. is focused in the North Pacific and JARPA around the Antarctic. JARPA mainly caught Antarctic minke whales, catching nearly 7,000; to a far lesser extent, they also caught fin whales. Animal-rights activist groups, such as the Greenpeace, object to Japan's scientific whaling, with some calling it a substitute for commercial whaling. In 2014, the International Court of Justice (the UN judicial branch) banned the taking of whales for any purpose in the Southern Ocean Whale Sanctuary; however, Japan refuses to stop whaling and has only promised to cut their annual catches by a third (around 300 whales per year).Baleen whales.

Baleen whale. vessel speed correlated with lower collision rates. The ever-increasing amount of ocean noise, including sonar, drowns out the vocalizations produced by whales, notably in the blue whale which produces the loudest vocalization, which makes it harder for them to communicate. Blue whales stop producing foraging D calls once a mid-frequency sonar is activated, even though the sonar frequency range (1–8 kHz) far exceeds their sound production range (25–100 Hz).Poisoning from toxic substances such as polychlorinated biphenyl (PCB) is generally low because of their low trophic level. However, oil spills can be a significant threat, especially to small populations; the already.

Baleen whale. endangered Rice's whale was likely devastated by the Deepwater Horizon oil spill, with some estimates indicating a decline of up to 22% in the species.Some baleen whales can become victims of bycatch, which is especially serious for North Atlantic right whales considering their small number. Right whales feed with a wide-open mouth, risking entanglement in any rope or net fixed in the water column. The rope wraps around their upper jaw, flippers and tail. Some are able to escape, but others remain entangled. If observers notice, they can be successfully disentangled, but others die over a period of months. Other.

Baleen whale. whales, such as humpback whales, can also be entangled.## In captivity.Baleen whales have rarely been kept in captivity. Their large size and appetite make them expensive creatures to maintain. Pools of proper size would also be very expensive to build. For example, a single gray whale calf would need to eat 475 (lbs) of fish per day, and the pool would have to accommodate the 13 (ft) calf, along with ample room to swim. Only gray whales have survived being kept in captivity for over a year. The first gray whale, which was captured in Scammon's Lagoon, Baja California Sur,.

Baleen whale. whales in the nearby bay enclosed by nets. One survived for three months, another (a calf) survived for two weeks, and another was kept for over a month before breaking through the nets.

Hooded crow. The hooded crow (Corvus cornix) (also called the scald-crow or hoodie) is a Eurasian bird species in the genus "Corvus". Widely distributed, it is found across Northern, Eastern, and Southeastern Europe, as well as parts of the Middle East. It is an ashy grey bird with black head, throat, wings, tail, and thigh feathers, as well as a black bill, eyes, and feet. Like other corvids, it is an omnivorous and opportunistic forager and feeder.The hooded crow is so similar in morphology and habits to the carrion crow ("Corvus corone") that for many years they were considered by most authorities.

Hooded crow. to be geographical races of one species. Hybridization observed where their ranges overlapped added weight to this view. However, since 2002, the hooded crow has been elevated to full species status after closer observation; the hybridisation was less than expected and hybrids had decreased vigour. Within the hooded crow species, four subspecies are recognized, with one, the Mesopotamian crow, possibly distinct enough to warrant species status itself.## Taxonomy.The hooded crow was one of the many species originally described by Carl Linnaeus in his landmark 1758 10th edition of "Systema Naturae"; he gave it the binomial name "Corvus cornix". Linnaeus specified.

Hooded crow. the type locality as "Europa", but this was restricted to Sweden by the German ornithologist Ernst Hartert in 1903. The genus name "Corvus" is Latin for "raven" while the specific epithet "cornix" is Latin for "crow". The hooded crow was subsequently considered a subspecies of the carrion crow for many years, hence known as "Corvus corone cornix", due to similarities in structure and habits. "Hooded crow" has been designated as the official name by the International Ornithologists' Union (IOC). It is locally known as a 'hoodie craw' or simply 'hoodie' in Scotland and as a grey crow in Northern Ireland.

Hooded crow. It is also known locally as "Scotch crow" and "Danish crow". In Irish, it is called "caróg liath", or the "grey crow", as its name also means in the Slavic languages and in Danish. It is referred to as the "mist crow" ("Nebelkrähe") in German, and the "dolman crow" ("dolmányos varjú") in Hungarian.## Subspecies.Four subspecies of the hooded crow are now recognised; previously, all were considered subspecies of "Corvus corone". A fifth subspecies, "C. c. sardonius" (Kleinschmidt, 1903) has been listed, although it has been alternately partitioned between "C. c. sharpii" (most populations), "C. c. cornix" (Corsican population), and the.

Hooded crow. Middle Eastern "C. c. pallescens". "C. c. cornix" Linnaeus, 1758 – the nominate race, occurs in Britain, Ireland and the rest of Europe south to Corsica. "C. c. sharpii" Oates, 1889 – named for English zoologist Richard Bowdler Sharpe. This is a paler grey form found from western Siberia through to the Caucasus region and Iran. "C. c. pallescens" (Madarász, 1904) – found in Turkey and Egypt, and is a paler form as its name suggests."C. c. capellanus" Sclater, PL, 1877 – sometimes considered a separate species. This distinctive form occurs in Iraq and southwestern Iran. It has very pale.

Hooded crow. grey plumage, which looks almost white from a distance. It is possibly distinct enough to be considered a separate species.## Genetic difference from carrion crows. The hooded crow ("Corvus cornix") and carrion crow ("Corvus corone") are two closely related species whose geographical distribution across Europe is illustrated in the accompanying diagram. It is believed that this distribution might have resulted from the glaciation cycles during the Pleistocene, which caused the parent population to split into isolates which subsequently re-expanded their ranges when the climate warmed causing secondary contact. Jelmer Poelstra and coworkers sequenced almost the entire genomes of both species.

Hooded crow. in populations at varying distances from the contact zone to find that the two species were genetically identical, both in their DNA and in its expression (in the form of "m"RNA), except for the "lack of expression" of a small portion (<0.28%) of the genome (situated on avian chromosome 18) in the hooded crow, which imparts the lighter plumage colouration on its torso. Thus the two species can viably hybridize, and occasionally do so at the contact zone, but the all-black carrion crows on the one side of the contact zone mate almost exclusively with other all-black carrion crows, while.

Hooded crow. the same occurs among the hooded crows on the other side of the contact zone. They concluded that it was only the outward appearance of the two species that inhibits hybridization.## Description.Except for the head, throat, wings, tail, and thigh feathers, which are black and mostly glossy, the plumage of the hooded crow is ash-grey, with the dark shafts giving it a streaky appearance. The bill and legs are black; the iris dark brown. Only one moult occurs, in autumn, as in other crow species. Male hooded crows tend to be larger than females, although the two sexes are otherwise.

Hooded crow. similar in appearance. Their flight is slow, heavy and usually straight. Their length varies from 48 to 52 (cm). When first hatched, the young are much blacker than the parents. Juveniles have duller plumage with bluish or greyish eyes, and initially possess a red mouth. Wingspan is 105 (cm) and weight is on average 510 g.The hooded crow, with its contrasted greys and blacks, is visually distinct from both the carrion crow and the rook, but the call notes of the hooded and carrion crows are almost indistinguishable.## Distribution.The hooded crow breeds in northern and eastern Europe, and closely allied.

Hooded crow. forms inhabit southern Europe and western Asia. Where its range overlaps with that of the carrion crow, as in northern Britain, Germany, Denmark, northern Italy, and Siberia, their hybrids are fertile. However, the hybrids are less well-adapted than purebred birds (one of the reasons behind its reclassification as a distinct species from the carrion crow). Little or no interbreeding occurs in some areas, such as Iran and central Russia.In the British Isles, the hooded crow breeds regularly in Scotland, the Isle of Man, and the Scottish Islands; it also breeds widely in Ireland. In autumn, some migratory birds arrive on.

Hooded crow. the east coast of Britain. In the past, this was a more common visitor.## Behaviour.## Diet.The hooded crow is omnivorous, with a diet similar to that of the carrion crow, and is a constant scavenger. It drops molluscs and crabs to break them after the manner of the carrion crow, to the point that an old Scottish name for empty sea urchin shells was "crow's cups". On coastal cliffs, the eggs of gulls, cormorants, and other birds are stolen when their owners are absent, and hooded crows will enter the burrows of puffins to steal eggs. It will also feed.

Hooded crow. on small mammals, scraps, smaller birds, and carrion. The hooded crow often hides food to feed on later, especially meat, nuts, and any insects that may be present on these, in places such as rain gutters, flower pots, or in the earth under bushes. Other crows will often watch a crow that hides food and then search the hiding place later when the first crow has left.## Nesting.Nesting occurs later in colder regions: mid-May to mid-June in northwest Russia, Shetland, and the Faroe Islands, and late February in the Persian Gulf region. In warmer parts of the European Archipelago, the.

Hooded crow. clutch is laid in April. The bulky stick nest is normally placed in a tall tree, but cliff ledges, old buildings, and pylons may be used. Nests are occasionally placed on or near the ground. The nest resembles that of the carrion crow, but on the coast, seaweed is often interwoven in the structure, and animal bones and wire are also frequently incorporated. The four to six brown-speckled blue eggs are 4.3 x 3.0 (cm) in size and weigh 19.8 (g), of which 6% is shell. The altricial young are incubated for 17–19 days by the female alone, that is.

Hooded crow. fed by the male. They fledge after 32 to 36 days. Incubating females have been reported to obtain most of their own food and later that for their young.The typical lifespan is unknown, but that of the carrion crow is four years. The maximum recorded age for a hooded crow is 16 years, and 9 months.This species is a secondary host of the parasitic great spotted cuckoo, the European magpie being the preferred host. However, in areas where the latter species is absent, such as Israel and Egypt, the hooded crow becomes the normal corvid host.This species, like its relative,.

Hooded crow. is regularly killed by farmers and on grouse estates. In County Cork, Ireland, the county's gun clubs shot over 23,000 hooded crows in two years in the early 1980s.## Status.The IUCN Red List does not distinguish the hooded crow from the carrion crow, but the two species together have an extensive range, estimated at 10 (e6km2), and a large population, including an estimated 14 to 34 million individuals in Europe alone. They are not believed to approach the thresholds for the population decline criterion of the IUCN Red List (i.e., declining more than 30% in ten years or three generations),.

Hooded crow. so are evaluated as least concern. The carrion crow and hooded crow hybrid zone is slowly spreading northwest, but the hooded crow has on the order of three million territories in just Europe (excluding Russia). This movement is also attested to by the fact that in April 2020 the hooded crow was redlisted in Sweden, where the Species Information Centre does distinguish between hooded and carrion crow.## Cultural significance.In Irish folklore, the bird appears on the shoulder of the dying Cú Chulainn, and could also be a manifestation of the Morrígan, the wife of Tethra, or the Cailleach. This idea.

Hooded crow. has persisted, and the hooded crow is associated with fairies in the Scottish highlands and Ireland; in the 18th century, Scottish shepherds would make offerings to them to keep them from attacking sheep. In Faroese folklore, a maiden would go out on Candlemas morn and throw a stone, then a bone, then a clump of turf at a hooded crow – if it flew over the sea, her husband would be a foreigner; if it landed on a farm or house, she would marry a man from there, but if it stayed put, she would remain unmarried.The old name of.

Hooded crow. Royston crow originates from the days when this bird was a common winter visitor to southern England, with the sheep fields around Royston, Hertfordshire providing carcasses on which the birds could feed. The local newspaper, founded in 1855, is called "The Royston Crow", and the hooded crow also features on the town's coat of arms.The hooded crow is one of the 37 Norwegian birds depicted in the Bird Room of the Royal Palace in Oslo. Jethro Tull mentions the hooded crow on the song "Jack Frost and the hooded crow" as a bonus track on the digitally remastered version of.

In 2014, Google together with IEEE started an open competition named Little Box Challenge, with a prize money of $1,000,000, to build a (much) smaller power inverter.## History.## Early inverters.From the late nineteenth century through the middle of the twentieth century, DC-to-AC power conversion was accomplished using rotary converters or motor-generator sets (M-G sets). In the early twentieth century, vacuum tubes and gas-filled tubes began to be used as switches in inverter circuits. The most widely used type of tube was the thyratron.The origins of electromechanical inverters explain the source of the term "inverter". Early AC-to-DC converters.

Morus (plant). Distribution.Black, red, and white mulberries are widespread in Southern Europe, the Middle East, northern Africa, and the Indian subcontinent, where the tree and the fruit have names under regional dialects. Black mulberry was imported to Britain in the 17th century in the hope that it would be useful in the cultivation of silkworms. It was much used in folk medicine, especially in the treatment of ringworm. Mulberries are also widespread in Greece, particularly in the Peloponnese, which in the Middle Ages was known as Morea, deriving from the Greek word for the tree (, "").## Cultivation.Mulberries can be grown from.
