Laser printing. Laser printing is an electrostatic digital printing process. It produces high-quality text and graphics (and moderate-quality photographs) by repeatedly passing a laser beam back and forth over a negatively-charged cylinder called a "drum" to define a differentially-charged image. The drum then selectively collects electrically-charged powdered ink (toner), and transfers the image to paper, which is then heated to permanently fuse the text, imagery, or both, to the paper. As with digital photocopiers, laser printers employ a xerographic printing process. Laser printing differs from traditional xerography as implemented in analog photocopiers in that in the latter, the image is formed by.

Laser printing. reflecting light off an existing document onto the exposed drum.Invented at Xerox PARC in the 1970s, laser printers were introduced for the office and then home markets in subsequent years by IBM, Canon, Xerox, Apple, Hewlett-Packard and many others. Over the decades, quality and speed have increased as prices have decreased, and the once cutting-edge printing devices are now ubiquitous.## History.In the 1960s, the Xerox Corporation held a dominant position in the photocopier market. In 1969, Gary Starkweather, who worked in Xerox's product development department, had the idea of using a laser beam to "draw" an image of what was.

Laser printing. to be copied directly onto the copier drum. After transferring to the recently formed Palo Alto Research Center (Xerox PARC) in 1971, Starkweather adapted a Xerox 7000 copier to make SLOT (Scanned Laser Output Terminal). In 1972, Starkweather worked with Butler Lampson and Ronald Rider to add a control system and character generator, resulting in a printer called EARS (Ethernet, Alto Research character generator, Scanned laser output terminal)—which later became the Xerox 9700 laser printer. 1976: The first commercial implementation of a laser printer, the IBM 3800, was released. It was designed for data centers, where it replaced line printers.

Laser printing. Japanese camera and optics company Canon developed the Canon LBP-10, a low-cost desktop laser printer. Canon then began work on a much-improved print engine, the Canon CX, resulting in the LBP-CX printer. Having no experience in selling to computer users, Canon sought partnerships with three Silicon Valley companies: Diablo Data Systems (who rejected the offer), Hewlett-Packard (HP), and Apple Computer. 1981: The first small personal computer designed for office use, the Xerox Star 8010, reached market. The system used a desktop metaphor that was unsurpassed in commercial sales, until the Apple Macintosh. Although it was innovative, the Star workstation was.

Laser printing. a prohibitively-expensive () system, affordable only to a fraction of the businesses and institutions at which it was targeted. 1984: The first laser printer intended for mass-market sales, the HP LaserJet, was released; it used the Canon CX engine, controlled by HP software. The LaserJet was quickly followed by printers from Brother Industries, IBM, and others. First-generation machines had large photosensitive drums, of circumference greater than the loaded paper's length. Once faster-recovery coatings were developed, the drums could touch the paper multiple times in a pass, and therefore be smaller in diameter. 1985: Apple introduced the LaserWriter (also based on.

Laser printing. page is known as a raster line or scan line.Laser printing differs from other printing technologies in that each page is always rendered in a single continuous process without any pausing in the middle, while other technologies like inkjet can pause every few lines. To avoid a buffer underrun (where the laser reaches a point on the page before it has the dots to draw there), a laser printer typically needs enough raster memory to hold the bitmap image of an entire page.Memory requirements increase with the square of the dots per inch, so 600 dpi requires a minimum of.

Laser printing. or 8,388,608 bits, which is just large enough to hold the entire page at 300 dpi, leaving about 100 kilobytes to spare for use by the raster image processor.In a color printer, each of the four CMYK toner layers is stored as a separate bitmap, and all four layers are typically preprocessed before printing begins, so a minimum of 4 megabytes is needed for a full-color letter-size or A4-size page at 300 dpi.During the 1980s, memory chips were still very expensive, which is why entry-level laser printers in that era always came with four-digit suggested retail prices in US dollars.

Laser printing. Memory prices later decreased significantly, while rapid improvements in the performance of personal computers and peripheral cables enabled the development of low-end laser printers which offload rasterization to the sending PC. For such printers, the operating system's print spooler renders the raw bitmap of each page into the PC's system memory at the target resolution, then sends that bitmap directly to the laser (at the expense of slowing down all other programs on the sending PC). The appearance of so-called "dumb" or "host-based" laser printers from NEC made it possible for the retail cost of low-end 600-dpi laser printers to.

Laser printing. decrease to as low as US$700 by early 1994 and US$600 by early 1995.1200 dpi printers have been widely available in the home market since 2008. 2400 dpi electrophotographic printing plate makers, essentially laser printers that print on plastic sheets, are also available.## Charging.In older printers, a corona wire positioned parallel to the drum or, in more recent printers, a primary charge roller, projects an electrostatic charge onto the photoreceptor (otherwise named the photoconductor unit), a revolving photosensitive drum or belt, which is capable of holding an electrostatic charge on its surface while it is in the dark.An AC bias.

Laser printing. silicon nitride.## Exposing.A laser printer uses a laser because lasers are able to form highly-focused, precise, and intense beams of light, especially over the short distances inside of a printer. The laser is aimed at a rotating polygonal mirror which directs the light beam through a system of lenses and mirrors onto the photoreceptor drum, writing pixels at rates up to sixty-five million times per second. The drum continues to rotate during the sweep, and the angle of sweep is canted very slightly to compensate for this motion. The stream of rasterized data held in the printer's memory rapidly turns.

Laser printing. the laser on and off as it sweeps.The laser beam neutralizes (or reverses) the charge on the surface of the drum, leaving a static electric negative image on the drum's surface which will repel the negatively-charged toner particles. The areas on the drum which were struck by the laser, however, momentarily have no charge, and the toner being pressed against the drum by the toner-coated developer roll in the next step moves from the roll's rubber surface to the charged portions of the surface of the drum.Some non-laser printers (LED printers) use an array of light-emitting diodes spanning the width.

Laser printing. uniformly heats the roller from the inside. For proper bonding of the toner, the fuser roller must be uniformly hot.Some printers use a very thin flexible metal foil roller, so there is less thermal mass to be heated and the fuser can more quickly reach operating temperature. If paper moves through the fuser more slowly, there is more roller contact time for the toner to melt, and the fuser can operate at a lower temperature. Smaller, inexpensive laser printers typically print slowly, due to this energy-saving design, compared to large high-speed printers where paper moves more rapidly through a high-temperature.

Laser printing. (on some very fast, expensive printers) a xenon flash lamp. The warmup process that a laser printer goes through when power is initially applied to the printer consists mainly of heating the fuser element.## Malfunctions.The mechanism inside a laser printer is somewhat delicate and, once damaged, often impossible to repair. The drum, in particular, is a critical component: it must not be left exposed to ambient light for more than a few hours, as light is what causes it to lose its charge and will eventually wear it out. Anything that interferes with the operation of the laser such as.

Laser printing. formulations may not match the original specifications in terms of either tendency to accept a negative charge, to move to the discharged areas of the photoreceptor drum from the developer roll, to fuse appropriately to the paper, or to come off the drum cleanly in each revolution.## Performance.As with most electronic devices, the cost of laser printers has decreased significantly over the years. In 1984, the HP LaserJet sold for $3500, had trouble with even small, low-resolution graphics, and weighed 32 (kg). By the late 1990s, monochrome laser printers had become inexpensive enough for home-office use, having displaced other printing.

Laser printing. technologies, although color inkjet printers (see below) still had advantages in photo quality reproduction. , low-end monochrome laser printers can sell for less than $75, and while these printers tend to lack onboard processing and rely on the host computer to generate a raster image, they nonetheless outperform the 1984 LaserJet in nearly all situations.Laser printer speed can vary widely, and depends on many factors, including the graphic intensity of the job being processed. The fastest models can print over 200 monochrome pages per minute (12,000 pages per hour). The fastest color laser printers can print over 100 pages per.

Laser printing. minute (6000 pages per hour). Very high-speed laser printers are used for mass mailings of personalized documents, such as credit card or utility bills, and are competing with lithography in some commercial applications.The cost of this technology depends on a combination of factors, including the cost of paper, toner, drum replacement, as well as the replacement of other items such as the fuser assembly and transfer assembly. Often printers with soft plastic drums can have a very high cost of ownership that does not become apparent until the drum requires replacement.Duplex printing (printing on both sides of the paper) can.

Laser printing. halve paper costs and reduce filing volumes, albeit at a slower page-printing speed because of the longer paper path. Formerly only available on high-end printers, duplexers are now common on mid-range office printers, though not all printers can accommodate a duplexing unit.In a commercial environment such as an office, it is becoming increasingly common for businesses to use external software that increases the performance and efficiency of laser printers in the workplace. The software can be used to set rules dictating how employees interact with printers, such as setting limits on how many pages can be printed per day, limiting.

Laser printing. usage of color ink, and flagging jobs that appear to be wasteful.## Color laser printers.Color laser printers use colored toner (dry ink), typically cyan, magenta, yellow, and black (CMYK). While monochrome printers only use one laser scanner assembly, color printers often have two or more, often one for each of the four colors.Color printing adds complexity to the printing process because very slight misalignments known as registration errors can occur between printing each color, causing unintended color fringing, blurring, or light/dark streaking along the edges of colored regions. To permit a high registration accuracy, some color laser printers use a.

Laser printing. Color laser transfer printers.Color laser transfer printers are designed to produce transfer media which are transfer sheets designed to be applied by means of a heat press. These transfers are typically used to make custom T-shirts or custom logo products with corporate or team logos on them.2-part Color laser transfers are part of a two-step process whereby the color laser printers use colored toner (dry ink), typically cyan, magenta, yellow, and black (CMYK); however, newer printers designed to print on dark T-shirts utilize a special white toner allowing them to make transfers for dark garments or dark business products.The CMYK.

Laser printing. color printing process allows for millions of colors to be faithfully represented by the unique imaging process.## Business-model comparison with inkjet printers.Manufacturers use a similar business model for both low-cost color laser printers and inkjet printers: the printers are sold cheaply while replacement toners and inks are relatively expensive. A color laser printer's average running cost per page is usually slightly less, even though both the laser printer and laser toner cartridge have higher upfront prices, as laser toner cartridges print many more sheets relative to their cost than inkjet cartridges. Inkjet printers are better at printing photographs and color.

Laser printing. records, and keeping in mind that there are color laser printers, they're more costly.The print quality of color lasers is limited by their resolution (typically 600–1200 dpi) and their use of just four color toners. They often have trouble printing large areas of the same or subtle gradations of color. Inkjet printers designed for printing photos can produce much higher quality color images. An in-depth comparison of inkjet and laser printers suggest that laser printers are the ideal choice for a high quality, volume printer, while inkjet printers tend to focus on large-format printers and household units. Laser printers offer.

Laser printing. more precise edging and in-depth monochromatic color. In addition, color laser printers are much faster than inkjet printers, although being generally larger and bulkier.## Anti-counterfeiting marks.Many modern color laser printers mark printouts by a nearly invisible dot raster, for the purpose of traceability. The dots are yellow and about 0.1 (mm) in size, with a raster of about 1 (mm). This is purportedly the result of a deal between the US government and printer manufacturers to help track counterfeiters. The dots encode data such as printing date, time, and printer serial number in binary-coded decimal on every sheet of paper.

Laser printing. printer users, this technique also increases waste, and thus increases pressure on the environment. For these toner cartridges (as with inkjet cartridges), reset devices can be used to override the limitation set by the smart chip. Also, for some printers, online walk-throughs have been posted to demonstrate how to use up all the ink in the cartridge. These chips offer no benefit to the end-user—some laser printers used an optical mechanism to assess the amount of remaining toner in the cartridge rather than using a chip to electrically count the number of printed pages, and the chip's only function was.

Laser printing. toner spills into the laser printer, a special type of vacuum cleaner with an electrically conductive hose and a high-efficiency (HEPA) filter may be needed for effective cleaning. These specialized tools are called "ESD-safe" (Electrostatic Discharge-safe) or "toner vacuums".## Ozone hazards.As a normal part of the printing process, the high voltages inside the printer can produce a corona discharge that generates a small amount of ionized oxygen and nitrogen, which react to form ozone and nitrogen oxides. In larger commercial printers and copiers, an activated carbon filter in the air exhaust stream breaks down these noxious gases to prevent pollution.

Laser printing. of the office environment.However, some ozone escapes the filtering process in commercial printers, and ozone filters are not used at all in most smaller home printers. When a laser printer or copier is operated for a long period of time in a small, poorly-ventilated space, these gases can build up to levels at which the odor of ozone or irritation may be noticed. A potential health hazard is theoretically possible in extreme cases.## Respiratory health risks.According to a 2012 study conducted in Queensland, Australia, some printers emit sub-micrometer particles which some suspect may be associated with respiratory diseases. Of 63.

Laser printing. printer emissions with adverse health outcomes were located" and that several assessments conclude that "risk of direct toxicity and health effects from exposure to laser printer emissions is negligible". The review also observes that, because the emissions have been shown to be volatile or semi-volatile organic compounds, "it would be logical to expect possible health effects to be more related to the chemical nature of the aerosol rather than the physical character of the ‘particulate’ since such emissions are unlikely to be or remain as ‘particulates’ after they come into contact with respiratory tissue".The German Social Accident Insurance has commissioned.

Laser printing. a human study project to examine the effects on health resulting from exposure to toner dusts and from photocopying and printing cycles. Volunteers (23 control persons, 15 exposed persons and 14 asthmatics) were exposed to laser printer emissions under defined conditions in an exposure chamber. The findings from the study based on a broad spectrum of processes and subjects fail to confirm that exposure to high laser printer emissions initiates a verifiable pathological process resulting in the reported illnesses.A much-discussed proposal for reducing emissions from laser printers is to retrofit them with filters. These are fixed with adhesive tape to.

Laser printing. the printer's fan vents to reduce particle emissions. However, all printers have a paper output tray, which is an outlet for particle emissions. Paper output trays cannot be provided with filters, so it is impossible to reduce their contribution to overall emissions with retrofit filters.## Air-transport ban.After the 2010 cargo plane bomb plot, in which shipments of laser printers with explosive-filled toner cartridges were discovered on separate cargo airplanes, the US Transportation Security Administration prohibited pass-through passengers from carrying toner or ink cartridges weighing over 1 (lb) on inbound flights, in both carry-on and checked luggage. "PC Magazine" noted that.

Mexican free-tailed bat. The Mexican free-tailed bat or Brazilian free-tailed bat ("Tadarida brasiliensis") is a medium-sized bat native to the Americas, regarded as one of the most abundant mammals in North America. Its proclivity towards roosting in huge numbers at relatively few locations makes it vulnerable to habitat destruction in spite of its abundance. It has been claimed to have the fastest horizontal speed (as opposed to stoop diving speed) of any animal, reaching top ground speeds over 162 (km/h); its actual air speed has not been measured. The Texas Legislature designated the Mexican free-tailed bat the state mammal (flying) in 1995.## Taxonomy.The.

Mexican free-tailed bat. Mexican free-tailed bat was described as a new species in 1824 by French zoologist Isidore Geoffroy Saint-Hilaire. Geoffroy placed it in the now-defunct genus "Nyctinomus" with a binomial name of "Nyctinomus brasiliensis".The holotype had been collected in Brazil.Molecular sequence data indicate "T. brasiliensis"'s closest relatives are the sister species "Sauromys petrophilus" of South Africa and "Tadarida aegyptiaca" of Africa and South Asia. These three species form a clade believed to be about 18 million years old.## Physical description.Mexican free-tailed bats are typically 9 (cm) in length and weigh around 7-12 ( g) with females tending to be slightly heavier than.

Mexican free-tailed bat. males by 1-2 grams for increased fat storage to use during gestation and nursing. Their tails are almost half their total length and stretch beyond the uropatagium, giving them the name "free-tailed" bats. Their ears are wide, rounded, and large compared to their heads, nearly meeting at the front of the face, but distinctly not joined at the midline and projecting anterodorsally from just before the muzzle to the back of the head. They use their large ears to help them find prey using echolocation. "T. brasiliensis" is distinguished among North American" Tadarida" bats in possessing deep wrinkles on the.

Mexican free-tailed bat. upper lip and in having a Z-shaped upper third molar, which is used for grinding insects. These individuals possess canines which are larger in males than in females. The wings are elongated and narrow with pointed tips, making them well-equipped for quick, straight flight patterns. Their fur color ranges from dark brown to gray. The Mexican free-tailed bat's large feet have distinct long, white bristles.The dental formula of "Tadarida brasiliensis" is .## Range and ecology.The Mexican free-tailed bat ranges from the southern half of the continental United States through most of Mexico, and through most of Central America into South.

Mexican free-tailed bat. America. Their range in South America is less understood where they live in the eastern Brazilian highlands and coast, the northeastern Andes, the coast of Peru and northern Chile, and the center of Argentina. They are absent in much of the Amazon rainforest. They are also found in the Caribbean, and are native to all of the Greater Antilles and 11 of the Lesser Antilles. The largest known colony is found at Bracken Cave, north of San Antonio, Texas, with nearly 20 million bats; the bats from this colony congregate in huge numbers at altitudes between 180 and 1,000 (m),.

Mexican free-tailed bat. Oriental into Jalisco, Sinaloa, and Sonora. Some bats that summer in Kansas, Oklahoma, eastern New Mexico, and Texas migrate southward to South Texas and Mexico. Some bat populations in other areas of North America do not migrate, but are residents and may make seasonal changes in roost sites. While this migration is extremely extensive, a way must exist for these bats to continuously congregate in the same roosts every year. "T. brasiliensis" bats have copious numbers of sebaceous glands covering their entire bodies. These glands leave a trace of a lasting scent to which other bats are sensitive. This odor.

Mexican free-tailed bat. onset of evening emergence from caves and the end of returns at dawn tend to correlate with sunset and sunrise, respectively, with dawn returns ending increasingly later in correlation to sunrise throughout the summer season. Reproductive females tended to emerge earlier in the evening and return later at dawn to gather the extra nutrients they require for reproduction and offspring care. "T. brasiliensis" bats spend around 60% of their active time foraging while aerial, mostly hunting at heights of 6 - 15 ( m). Individuals will fly 50 (km) in one night to reach foraging areas. The loose, wrinkled skin.

Mexican free-tailed bat. around the mouth is thought to aid in expanding the mouth during flight to catch insects. "T. brasiliensis" requires free water sources to maintain water balance: individuals from the arid environment of New Mexico tend to have thicker renal tissue layers compared to "T. brasiliensis" from the less arid California, revealing that urine concentrating abilities and water use varies geographically with aridity.## Health and mortality.One individual bat was recorded to have lived 8 years, based on dentition. Predators of the bat include large birds such as red-tailed hawk, American kestrels, great horned owls, barn owls, and Mississippi kites. Mammal predators.

Mexican free-tailed bat. include Virginia opossums, striped skunks, and raccoons. Snakes such as eastern coachwhips and gopher snakes may also prey on them, but at a lesser extent. Certain types of beetles prey on neonate and juvenile bats that have fallen to the ground. This species seems to have a low incidence of rabies, at least in the United States. They do, however, contain certain pesticides.White-nose syndrome (WNS) caused by infection by the fungus "P. destructans" has increased in prevalence since 2006, mostly affecting species of bats that roost underground such as the little brown bat. The fungus, now suspected to have spread.

Mexican free-tailed bat. from accidental transportation by human cave workers, is thought to cause frequent arousals during bat hibernation, causing an individual to use fat stores much more quickly and die of starvation before the end of winter. WNS can affect "T. brasiliensis", but has yet to be greatly introduced to their habitat due to their preference for more arid caves. WNS has low prevalence in the subtropical and tropical regions where "T. brasiliensis" resides.## Behavior.Mexican free-tailed bats are nocturnal foragers and begin feeding after dusk. They travel 50 km in a quick, direct flight pattern to feed. This species flies the highest.

Mexican free-tailed bat. among bats, at altitudes around 3300 m. Bats appear to be most active in late morning and afternoon between June and September. Free-tailed bats are more active in warm weather.The species has been measured at a ground speed of 160 (km/h), measured by an aircraft tracking device. The measurement methodology did not simultaneously record wind speed and ground speed, so the observations could have been affected by strong local gusts, and the bat's maximum air speed remains uncertain.## Guano and ammonia.Among bats that roost in great, concentrated numbers, "T." "brasiliensis" roosts produce large quantities of urine and guano; from 22.

Mexican free-tailed bat. to 99 metric tons per cave and over 18,700 metric tons are produced annually. The concentrated waste generates high levels of toxic ammonia in the air of a cave. "T. brasiliensis" individuals have genetic adaptation for withstanding or countering these high levels of ammonia. The bats’ content of CO2 and protein in respiratory mucus and CO2 dissolved in blood plasma increase with increasing levels of dissolved ammonia, providing the bats with a buffer against pH change. This allows the bats to filter out a large majority of inhaled ammonia before it reaches toxic levels in the blood. "T. brasiliensis" bats.

Mexican free-tailed bat. are thought to swarm in spiraling motions within caves to ventilate ammonia and renew the air.## Echolocation.Mexican free-tailed bats use echolocation for navigation and detecting prey. Traveling calls are of a brief but constant frequency. However, they switch modulated frequency calls between 40 and 75 kHz if they detect something. Typically, the frequency range of their echolocation is between 49 and 70 kHz, but can be between 25 and 40 kHz if something crosses their path while in flight.On 6 November 2014, Aaron Corcoran, a biologist at Wake Forest University, North Carolina, reported online in "Science" that his team and.

Mexican free-tailed bat. he had detected Mexican free-tailed bats emitting ultrasonic vocalizations that had the effect of jamming the echolocation calls of a rival bat species hunting moths. The ‘jamming’ call led to an increased chance of the rival missing its prey, which the Mexican free-tailed bat was then able to eat itself. Earlier researchers had discovered some 15 types of social calls made by Mexican free-tailed bats and reported that they could adjust their calls to avoid interfering with others in range of their calls.## Mating and reproduction.During the breeding season, females aggregate into maternity roosts. The size of these roosts depends.

Mexican free-tailed bat. on the environment, with caves having the larger roosts. Mating can occur in an aggressive or passive form. In the aggressive form, the male controls the female's movements, keeping her away from the other bats in the roost. He also tends to vocalize when mating. During passive copulation, the males simply flies to a female in her roost and quietly mounts her with no resistance. This species is a promiscuous breeder and both sexes copulate with multiple partners. Females become sexually mature at about 9 months, while males take even longer, at two years. Females enter estrus once a year,.

Reflecting telescope. A reflecting telescope (also called a reflector) is a telescope that uses a single or a combination of curved mirrors that reflect light and form an image. The reflecting telescope was invented in the 17th century by Isaac Newton as an alternative to the refracting telescope which, at that time, was a design that suffered from severe chromatic aberration. Although reflecting telescopes produce other types of optical aberrations, it is a design that allows for very large diameter objectives. Almost all of the major telescopes used in astronomy research are reflectors. Reflecting telescopes come in many design variations and may.

Reflecting telescope. employ extra optical elements to improve image quality or place the image in a mechanically advantageous position. Since reflecting telescopes use mirrors, the design is sometimes referred to as a catoptric telescope.From the time of Newton to the 1800s, the mirror itself was made of metal usually speculum metal. This type included Newton's first designs and even the largest telescopes of the 19th century, the Leviathan of Parsonstown with a 1.8 meter wide metal mirror. In the 19th century a new method using a block of glass coated with very thin layer of silver began to become more popular by.

Reflecting telescope. his telescope and five years before Hooke built the first such Gregorian telescope, Isaac Newton in 1668 built his own reflecting telescope, which is generally acknowledged as the first reflecting telescope. It used a spherically ground metal primary mirror and a small diagonal mirror in an optical configuration that has come to be known as the Newtonian telescope.Despite the theoretical advantages of the reflector design, the difficulty of construction and the poor performance of the speculum metal mirrors being used at the time meant it took over 100 years for them to become popular. Many of the advances in reflecting.

Reflecting telescope. useful for terrestrial observations. Some small spotting scopes are still built this way. There are several large modern telescopes that use a Gregorian configuration such as the Vatican Advanced Technology Telescope, the Magellan telescopes, the Large Binocular Telescope, and the Giant Magellan Telescope.## Newtonian.The Newtonian telescope was the first successful reflecting telescope, completed by Isaac Newton in 1668. It usually has a paraboloid primary mirror but at focal ratios of about f/10 or longer a spherical primary mirror can be sufficient for high visual resolution. A flat secondary mirror reflects the light to a focal plane at the side of.

Reflecting telescope. seldom faster than f/15.## Off-axis designs.There are several designs that try to avoid obstructing the incoming light by eliminating the secondary or moving any secondary element off the primary mirror's optical axis, commonly called off-axis optical systems.## Herschelian.The Herschelian reflector is named after William Herschel, who used this design to build very large telescopes including the 40-foot telescope in 1789. In the Herschelian reflector the primary mirror is tilted so the observer's head does not block the incoming light. Although this introduces geometrical aberrations, Herschel employed this design to avoid the use of a Newtonian secondary mirror since the speculum.

White-breasted nuthatch. The white-breasted nuthatch (Sitta carolinensis) is a species of bird in the nuthatch family Sittidae. It is a medium-sized nuthatch, measuring approximately 15.5 (cm) in length. Coloration varies somewhat along the species' range, but the are light blue-gray, with a black and nape in males, while females have a dark gray crown. The are whitish, with a reddish tinge on the lower abdomen. The white-breasted nuthatch is a noisy bird. It has a nasal voice and often utters little cries or vocalizations, often composed of repetitions of small invariant whistles. In summer, it is an exclusively insectivorous bird, consuming a.

White-breasted nuthatch. slightly distinct distributions, vocalizations, and coloration. The species was once thought to be related to the white-cheeked nuthatch ("S. leucopsis") and Przewalski's nuthatch ("S. przewalskii"), two species from southern Asia, but is actually more closely related to the giant nuthatch ("S. magna"), also from Southeast Asia. The species enjoys a very wide distribution and its population is said to be increasing; the International Union for the Conservation of Nature therefore considers it to be of "least concern."## Taxonomy.The nuthatches are a genus, "Sitta", of small passerine birds which derive their English name from the tendency of some species to wedge.

White-breasted nuthatch. large insects or seeds into cracks, and then hack at them with their strong bills. "Sitta" is derived from "sittē", Ancient Greek for nuthatch, and "carolinensis" means "of Carolina" in Latin. The white-breasted nuthatch was first described by English ornithologist John Latham in his 1790 work, the "Index Ornithologicus". German ornithologist Hans Edmund Wolters proposed the division of the genus "Sitta" into subgenera in 1975–1982. The white-breasted nuthatch is placed in "Sitta" ("Leptositta") , alongside the white-cheeked nuthatch ("S. leucopsis") and Przewalski's nuthatch ("S. przewalskii").Nuthatch taxonomy is complex, with geographically separated species sometimes closely resembling each other. The white-breasted nuthatch.

White-breasted nuthatch. has an appearance and contact call similar to those of the white-cheeked nuthatch, of the Himalayas and was formerly considered to be conspecific with it. A study published in 2012 showed that four distinct lineages were genetically isolated from each other and could represent different species, recognizable by morphology and song. A molecular phylogeny published in 2014 and including all main species' lineages within nuthatches concluded that the white-breasted nuthatch was more closely related to the giant nuthatch ("S. magna") than to Przewalski's nuthatch, formerly regarded as possibly conspecific with it; Przewalski's nuthatch turned out to be basal in the.

White-breasted nuthatch. northeastern United States, at least 10% of females have black caps, but the proportion rises to 40–80% in the Rocky Mountains, Mexico and the southeastern U.S. Juveniles are similar to the adult, but duller plumaged.Three other, significantly smaller, nuthatches have ranges which overlap that of white-breasted, but none has white plumage completely surrounding the eye. Further distinctions are that the red-breasted nuthatch has a black eye line and reddish underparts, and the brown-headed and pygmy nuthatches each have a brown cap, and a white patch on the nape of the neck.## Geographical variation.The white-breasted nuthatch has nine subspecies, although the.

White-breasted nuthatch. differences are small and change gradually across the range. The subspecies are sometimes treated as three groups based on close similarities in morphology, habitat usage, and vocalizations. These groups cover eastern North America, the Great Basin and central Mexico, and the Pacific coastal regions. The subspecies of the western interior have the darkest upperparts, and eastern "S. c. carolinensis" has the palest back. The eastern form also has a thicker bill and broader dark cap stripe than the interior and Pacific races. The calls of the three groups differ, as described above.## Similar species.Only three other species of nuthatches inhabit.

White-breasted nuthatch. North America: the red-breasted nuthatch ("S. canadensis"), the pygmy nuthatch ("S. pygmaea") and the brown-headed nuthatch ("S. pusilla"), and their distributions overlap with those of the white-breasted nuthatch. They are, however, clearly distinct and much smaller, since they are the smallest nuthatches, measuring 10 centimeters long and weighing around 10 grams. The red-breasted nuthatch has reddish underparts and has a black stripe on the eye. The pygmy nuthatch and the brown-headed nuthatch have a brown crown with a white spot on the nape.## Distribution and habitat.The breeding habitat of the white-breasted nuthatch is woodland across North America, from southern Canada.

White-breasted nuthatch. pygmy and brown-headed nuthatches prefer pines.The presence of mature or decaying trees with holes suitable for nesting is essential, and trees such as oak, beech and hickory are favored in the east since they also provide edible seeds. White-breasted nuthatches seldom excavate their own nest holes like red-breasted nuthatches. Although suitable habitat is distributed continentally, it is discontinuous. The separate populations of this non-migratory species have diverged to form distinct regional subspecies.The white-breasted nuthatch, like most of its genus, is non-migratory, and the adults normally stay in their territory year-round. There may be more noticeable dispersal due to seed failure.

One bird landed on the RMS "Queen Mary" six hours' sailing east of New York City in October 1963.## Ecology and behavior.The white-breasted nuthatch often travels with small mixed flocks in winter. These flocks are led by titmice and chickadees, with nuthatches and downy woodpeckers as common attendant species. Participants in such flocks are thought to benefit in terms of foraging and predator avoidance. It is likely that the attendant species also access the information carried in.

White-breasted nuthatch. territory and either establish their own territory or become "floaters", unpaired birds without territories. It is probably these floaters which are mainly involved in the irregular dispersals of this species. This species of nuthatch roosts in tree holes or behind loose bark when not breeding and has the unusual habit of removing its feces from the roost site in the morning. It usually roosts alone except in very cold weather, when up to 29 birds have been recorded together.## Voice.Like other nuthatches, the white-breasted nuthatch is a noisy bird with a range of vocalizations. The male's mating song is a.

White-breasted nuthatch. strong legs and feet. All nuthatches are distinctive when seeking food because they are able to descend tree trunks head-first and can hang upside-down beneath twigs and branches.The white-breasted nuthatch is omnivorous, eating insects and seeds. It places large food items such as acorns or hickory nuts in crevices in tree trunks, and then hammers them open with its strong beak; surplus seeds are cached under loose bark or crevices of trees. The diet in winter may be nearly 70% seeds, but in summer it is mainly insects. The insects consumed by the white-breasted nuthatch include caterpillars, ants, and pest.

White-breasted nuthatch. species such as pine weevils, oystershell and other scale insects, and jumping plant lice. This bird will occasionally feed on the ground, and readily visits feeding stations for nuts, suet and sunflower seeds, the last of which it often takes away to store. The white-breasted nuthatch was also observed visiting raccoon latrines in order to find seeds.## Predators and parasites.Predators of adult nuthatches include owls and diurnal birds of prey (such as sharp-shinned and Cooper's hawks), and nestlings and eggs are eaten by woodpeckers, small squirrels, and climbing snakes such as the western rat snake. The white-breasted nuthatch responds to.

White-breasted nuthatch. and nine months.The white-breasted nuthatch's responses to predators may be linked to a reproductive strategy. A study compared the white-breasted nuthatch with the red-breasted nuthatch in terms of the willingness of males to feed incubating females on the nest when presented with models of predators. The models were of a sharp-shinned hawk, which hunts adult nuthatches, and a house wren, which destroys eggs. The white-breasted nuthatch is shorter-lived than the red-breasted nuthatch, but has more young, and was found to respond more strongly to the egg predator, whereas the red-breasted showed greater concern with the hawk. This supports the theory.

White-breasted nuthatch. for this species because it requires cavity sites for nesting; declines have been noted in Washington state, Florida, and more widely in the southeastern U.S. west to Texas. In contrast, the breeding range is expanding in Alberta, and numbers are increasing in the northeast due to regrown forest. The white-breasted nuthatch is protected under the Migratory Bird Treaty Act of 1918, to which the three countries in which it occurs (Canada, Mexico, and the United States) are all signatories.

Marble Church, Bodelwyddan. St Margaret's Church (nicknamed The Marble Church), Bodelwyddan, is a Decorated Gothic Style parish church in the lower Vale of Clwyd in Denbighshire, Wales and is visible for many miles because its spire rises to 202 feet. It lies just off the A55 trunk road.The church was erected by Lady Margaret Willoughby de Broke (daughter of Sir John Williams of nearby Bodelwyddan Castle) in memory of her husband, Henry Peyto-Verney, 16th Baron Willoughby de Broke. She laid the foundation stone on 24 July 1856 and the new church designed by John Gibson was consecrated by the Bishop of St Asaph.

The new parish of Bodelwyddan was created on 3 August 1860, from the communities of Bodelwyddan, Faenol and Pengwern, which until that date had been part of the parish of St Asaph. When it was first built, it was nicknamed the 'Pearl of the Vale'.The church contains fourteen varieties of marble including pillars made of Belgian Red marble, a nave entrance is made from Anglesey marble and shafts of Languedoc marble on bases of Purbeck marble. It also contains elaborate woodwork, and in the tower can be found windows.

This species is similar to the Syrian woodpecker.This woodpecker occurs in all types of woodlands and eats a variety of foods, being capable of extracting seeds from pine cones, insect larvae from inside trees or eggs and chicks of other birds from their nests. It breeds in holes excavated in living or dead trees, unlined apart from wood chips. The typical clutch is four to six glossy white eggs. Both parents incubate the.

Great spotted woodpecker. eggs, feed the chicks, and keep the nest clean. When the young fledge they are fed by the adults for about ten days, each parent taking responsibility for feeding part of the brood.The species is closely related to some other members of its genus. It has a number of subspecies, some of which are distinctive enough to be potential new species. It has a huge range and large population, with no widespread threats, so it is classed as a species of least concern by the International Union for Conservation of Nature (IUCN).## Taxonomy.Woodpeckers are an ancient bird family consisting of.

Great spotted woodpecker. the nominate subspecies "D. m. major".The fossil subspecies "D. m. submajor" lived during the Middle Pleistocene Riss glaciation (250,000 to 300,000 years ago) when it was found in Europe south of the ice sheet. It is sometimes treated as a distinct species, but did not differ significantly from the extant great spotted woodpecker, whose European subspecies are probably its direct descendants.## Description.An adult great spotted woodpecker is 20 – 24 (cm) long, weighs 70 – 98 (g) and has a 34 – 39 (cm) wingspan. The upperparts are glossy blue-black, with white on the sides of the face and neck.

Vagrants have reached the Faroe Islands, Hong Kong and Iceland, and there are several sightings from North America in at least the Aleutian Islands, Pribilof Islands and Alaska.Due to deforestation, this woodpecker was extirpated in Ireland in the seventeenth century, but the island has been naturally recolonised, with the first proven nesting in County Down in 2007. Its expansion in range is continuing, with breeding proven or suspected in at least 10 counties by 2013, with the main concentration in Down and County Wicklow. Genetic.

The outer layer of the upper mandible is significantly longer than the more rigid lower mandible and absorbs much of the concussive force. Skeletal adaptations and strengthening also help to absorb the shock, and narrow nostrils protect against flying debris.As well as using holes for breeding, great spotted woodpeckers roost at night, and sometimes during the day, in old nest cavities, excavated by other woodpeckers. They will occasionally make a new roosting hole or use an artificial site such as a nest box.## Breeding.Great spotted woodpeckers.

Great spotted woodpecker. four to six glossy white eggs that measure 27 x 20 (mm) and weigh about 5.7 (g), of which 7% is shell. They are laid from mid-April to June, the later dates being for birds breeding in the north of the range or at altitude. The eggs are incubated by either adult during the day and by the male at night, for 10–12 days before hatching. Both birds brood and feed the altricial naked chicks and keep the nest clean. The young fledge in 20–23 days from hatching. Each parent then takes responsibility for feeding part of the brood for.

Great spotted woodpecker. about ten days, during which time they normally remain close to the nest tree.There is only one brood per year. The survival rates for adults and young are unknown, as is the average lifespan, but the maximum known age is just over 11 years.## Feeding.The great spotted woodpecker is omnivorous. It digs beetle larvae from trees and also takes many other invertebrates including adult beetles, ants and spiders. The bird also digs for Lepidoptera larvae like "Acronicta rumicis". Crustaceans, molluscs and carrion may be eaten, and bird feeders are visited for seeds, suet and domestic scraps. The nests of other.

Medici Fountain. The Medici Fountain () is a monumental fountain in the Jardin du Luxembourg in the 6th arrondissement in Paris. It was built in about 1630 by Marie de' Medici, the widow of King Henry IV of France and regent of King Louis XIII of France. It was moved to its present location and extensively rebuilt in 1864-66.## Italian influence in Paris in the 17th century.The period between the regency of Catherine de' Medici in France (1559–1589) and that of Marie de' Medici (1610–1642) saw a great flourishing of the Italian mannerist style in France, A community of artists from Florence,.

The new palace was modeled after the Palazzo Pitti in her native Florence, and the gardens around the palace were modeled after those of the Boboli Gardens in Florence. The Palace was the work of architect Salomon de Brosse, but the fountain and grotto was most probably the work of Tommaso Francini, the Intendant General of Waters and Fountains of the King.

Medici Fountain. and was naturalized in 1600, had built grottos and fountains in the Italian style for the marquis de Gondi and for the royal chateau of Henry IV at Saint-Germain-en-Laye.The first difficulty of construction was the lack of water in the Left Bank of Paris. Unlike the Right Bank, where the water table was near the surface, and there were many wells and two aqueducts which served the city, the water table on the Left Bank was deep underground and all water had to be carried from the Seine. As a result, the city had expanded far from the Right Bank.

This problem was finally solved by the construction of the aqueduct of Arcueil, between 1613 and 1623.## 19th Century modifications.After the death of Marie de' Medici, the Palace and fountain went through a series of owners. By the middle of the 18th century, when the fountains of Versailles and the Garden à la française were in fashion, the Medici Fountain fell into disrepair. The two original statues at the top of the fountain, by the sculptor Pierre Biard, two nymphs pouring water from pitchers, had disappeared, and.

From 1858 to 1864, The new architect, Alphonse de Gisors, moved the fountain thirty meters to make room for the street, and radically changed its setting and appearance. Since the fountain no longer stood against a wall, the Fontaine de Léda, displaced from another neighborhood, was placed directly behind it. (See the Fountain of Leda, below.) He replaced the two original statues of nymphs at the top of the statue with two new statues, representing the Rivers Rhone and Seine. He restored the coat of arms of the Medici family over the fountain,.

Medici Fountain. and that is the fountain as it appears today. ## The Hidden Fountain - the Fountain of Léda.The fountain which Gisors placed behind the Medici Fountain had a history of its own. The Fontaine de Léda had been constructed in 1806-1809, during the First Empire, at the corner of rue Vaugirard and rue du Regard. It was the work of architect François-Jean Bralle and sculptor Achille Valois.

Adult sea otters typically weigh between 14 and 45 (kg), making them the heaviest members of the weasel family, but among the smallest marine mammals. Unlike most marine mammals, the sea otter's primary form of insulation is an exceptionally thick coat of fur, the densest in the animal kingdom. Although it can walk on land, the sea otter is capable of living exclusively in the ocean.The sea otter inhabits nearshore environments, where it dives to the sea floor to.

Fringe-like plaiting and braiding adorned the costumes of the time and were captured in their stone statuary.Arab weavers knotted excess thread along the edges of hand-loomed fabrics such as towels,.

Macramé. shawls, and veils into decorative fringes. The word "macramé" is derived from the Arabic "macramia" (), believed to mean "striped towel", "ornamental fringe" or "embroidered veil". Another school of thought indicates that it comes from Turkish "makrama", "napkin" or "towel". The decorative fringes also helped to keep flies off camels and horses in northern Africa.The Moorish conquest took the craft to Spain, then Italy, especially in the region of Liguria, then it spread through Europe. In England, it was introduced at the court of Mary II in the late 17th century. Queen Mary taught it to her ladies-in-waiting.Macramé was most.

Macramé. popular in the Victorian era. It adorned most homes in items such as tablecloths, bedspreads and curtains. The popular "Sylvia's Book of Macramé Lace" (1882) showed how "to work rich trimmings for black and coloured costumes, both for home wear, garden parties, seaside ramblings, and balls—fairylike adornments for household and underlinens ...".It was a specialty in Genoa, and was popular in the 19th century. There, "Its roots were in a 16th-century technique of knotting lace known as "punto a groppo"" Sailors made macramé objects while not busy at sea, and sold or bartered them when they landed. Nineteenth-century British and.

Macramé. American sailors made hammocks, bell fringes, and belts from macramé. They called the process "square knotting" after the knot they used most often. Sailors also called macramé "McNamara's lace".Macramé's popularity faded, but resurged in the 1970s for making wall hangings, clothing accessories, small jean shorts, bedspreads, tablecloths, draperies, plant hangers and other furnishings. Macramé jewelry became popular in America. Using mainly square knots and granny knots, this jewelry often features handmade glass beads and natural elements such as bone and shell. Necklaces, anklets and bracelets have become popular forms of macramé jewelry. By the early 1980s, macramé again began to.

Macramé. fall out of fashion, only to be revived by millennials.## Materials and process.Materials used in macramé include cords made of cotton twine, linen, hemp, jute, leather or yarn. Cords are identified by construction, such as a 3-ply cord, made of three lengths of fibre twisted together. Jewelry is often made in combination of both the knots and various beads (of glass, wood, and so on), pendants or shells. Sometimes 'found' focal points are used for necklaces, such as rings or gemstones, either wire-wrapped to allow for securing or captured in a net-like array of intertwining overhand knots. A knotting board.

Macramé. is often used to mount the cords for macramé work. Cords may be held in place using a C-clamp, straight pins, T-pins, U-pins, or upholstery pins.For larger decorative pieces, such as wall hangings or window coverings, a work of macramé might be started out on a wooden or metal dowel, allowing for a spread of dozens of cords that are easy to manipulate. For smaller projects, push-pin boards are available specifically for macramé, although a simple corkboard works adequately. Many craft stores offer beginners' kits, work boards, beads and materials ranging in price for the casual hobbyist or ambitious crafter.

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;.

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.

Instruction: I want to find a paragraph from Wikipedia that answers my question about this image.

American pika. The American pika (Ochotona princeps), a diurnal species of pika, is found in the mountains of western North America, usually in boulder fields at or above the tree line. They are herbivorous, smaller relatives of rabbits and hares. Pikas have two different ways of foraging; they either directly consume food or they cache food in piles for the winter (haying).Pikas are vocal, using both calls and songs to warn when predators are nearby and during the breeding season. Predators of the pika include eagles, hawks, coyotes, bobcats, foxes, and weasels.Recent studies suggest some populations are declining due to habitat loss.

American pika. of pika, it is one of only two which inhabit North America, along with the collared pika ("O. collaris"). In relation to the distribution of the American pika, the collared pika is located farther north of those regions and is separated by a gap of about 500 (mi) extending across British Columbia and Alberta.Pikas inhabit talus fields that are fringed by suitable vegetation on alpine areas. They also live in piles of broken rock. Sometimes, they live in man-made substrate such as mine tailings and piles of scrap lumber. Pikas usually have their den and nest sites below rock around.

American pika. 0.2–1 m in diameter, but often sit on larger and more prominent rocks. They generally reside in scree near or above the tree line. Pikas are restricted to cool, moist microhabitats on high peaks or watercourses. Intolerant of high diurnal temperatures, in the northern portion of their range, they may be found near sea level, but in the south they are rare below 2500 (m). Pikas rely on existing spaces in the talus for homes and do not dig burrows. However, they can enlarge their homes by digging.## Diet.The American pika is a generalist herbivore. It eats a large variety.

American pika. of green plants, including different kinds of grasses, sedges, thistles, and fireweed. Although a pika can meet its water demand from the vegetation eaten, it does drink water if it is available in its environment.Pikas have two different ways of foraging; they directly consume food (feeding) or they cache food in haypiles to use for a food source in the winter (haying). They feed throughout the year while haying is limited to the summer. Since they do not hibernate, pikas have greater energy demands than other montane mammals. They also make 13 trips per hour to collect vegetation when haying,.

American pika. up to a little over 100 trips per day. The timing of haying seems to correlate to the amount of precipitation from the previous winter. Pikas start and then quit haying earlier in years following little snow and early spring. In areas at lower elevations, haying begins before the snow has melted at high altitudes; at higher elevations, haying continues after it ends in lower elevations.When haying, pikas harvest plants in a deliberate sequence, corresponding to their seasonal phenology. They seem to assess the nutritional value of available food and harvest accordingly. Pikas select plants that have the higher caloric,.

American pika. protein, lipid, and water content. Forbs and tall grass tend to be hayed more than eaten directly. Haypiles tend to be stored under the talus near the talus-meadow interface, although they may be constructed on the talus surface. Males generally store more vegetation than females and adults usually store more than juveniles. Pikas deposit two kinds of fecal droppings: Hard, brown, round pellets and pellets that are soft black shiny strings that form in the caecum. Caecal pellets have more energy value than stored plant food and the pika may consume them directly or store them for later.## Life history.The.

American pika. American Pika is diurnal. The total area of land that an American Pika uses is known as a home range. About 55% of its home range is territory that the Pika defends against intruders. Territory size can vary from 410–709 m² and is dependent on configuration, distance to vegetation, and quality of vegetation. The home ranges of Pikas may overlap, with the distances of the home ranges of a mating pair being shorter than that of the nearest neighbors of the same sex. Spatial distances between adults of a pair is greatest during early and midsummer and reduces during late.

American pika. summer and early autumn. Pikas defend their territories with aggression. Actual aggressive encounters are rare and usually occur between members of the same sex and those unfamiliar with each other. A Pika may intrude on another's territory, but usually when the resident is not active. During haying, territorial behavior increases.Adult Pikas of the opposite sex with territories adjacent form mated pairs. When more than one male is available, females exhibit mate choice. Pikas are reflex ovulators; ovulation only occurs after copulation, and they are also seasonally polyestrous. A female has two litters per year and these litters average three young.

American pika. each. Breeding takes place one month before the snow melts and gestation lasts around 30 days. Parturition occurs as early as March in lower elevations, but occurs from April to June at higher elevations. Lactation significantly reduces a female's fat reserves and they only nurse the second litter if the first does not survive, despite exhibiting postpartum estrus. Pikas are born slightly altricial, being blind, slightly haired, and having fully erupted teeth. They weigh between 10 and 12 g at birth. At around nine days old, they are able to open their eyes. Mothers forage most of the day and.

American pika. return to the nest once every two hours to nurse the young. Young become independent after four weeks, around the same time they are weaned. Young may remain in their natal or an adjoining home range. When in their home range, young occupy areas away from their relatives as much as possible. Dispersal appears to be caused by competition for territories.Pikas are vocal, using both calls and songs to communicate among themselves. A call is used to warn when a predator is lurking nearby, and a song is used during the breeding season (males only), and during autumn (both males.

American pika. and females). Predators of the Pika include eagles, hawks, coyotes, bobcats, foxes, and weasels.## Taxonomy.The American pika was described in the scientific literature by John Richardson in "Fauna Boreali-Americana" in 1828. The original scientific name was "Lepus (Lagomys) princeps".## Conservation and decline.As they live in the high and cooler mountain regions, they are very sensitive to high temperatures, and are considered to be one of the best early warning systems for detecting global warming in the western United States. Temperature increases are suspected to be one cause of American pikas moving higher in elevation in an attempt to find suitable.

American pika. habitat, as well as cooler temperatures. American pikas, however, cannot easily migrate in response to climate change, as their habitat is currently restricted to small, disconnected habitat "islands" in numerous mountain ranges. Pikas can die in six hours when exposed to temperatures above 25.5 (°C) if individuals cannot find refuge from heat. In warmer environments, such as during midday sun and at lowerelevation limits, pikas typically become inactive and withdraw into cooler talus openings. Because of behavioral adaptation, American pikas also persist in the hot climates of Craters of the Moon and Lava Beds National Monuments (Idaho and California, respectively).

American pika. species of least concern.The Pikas in Peril Project, funded through the National Park Service Climate Change Response Program, began data collection in May 2010. A large team of academic researchers and National Park Service staff - from three universities and eight national parks - worked together to address questions regarding the vulnerability of the American pika to future climate change scenarios projected for the western United States. The project concluded in 2016.More recent studies have found widespread extirpations and range retractions at lower elevations which are typically warmer and drier, patterns that have been further attributed to varying aspects of.

American pika. climate change such as warmer summer and winter temperatures and changes in precipitation. For example, one study found upslope retractions in 44 of 64 watersheds surveyed in the Northern Rockies, with retractions averaging 281 meters. Another study in North Cascades National Park in Washington found that a single winter of little to no snow caused drastic declines in pika abundance, highlighting how snowpack provides a necessary insulation against cold winter temperatures.
