at bat

At-bat Definition: an official turn as a batter: a turn as a batter is not recognized as being official if | Bedeutung, Aussprache, Übersetzungen und Beispiele. Viele übersetzte Beispielsätze mit "at bat" – Deutsch-Englisch Wörterbuch und Suchmaschine für Millionen von Deutsch-Übersetzungen. Eine At-Bat-Situation. Der Batter (auf Deutsch auch Schlagmann) ist derjenige Offensivspieler im Baseball- und Softball-Sport, der gerade versucht, den Ball zu schlagen. Batter und Hitter sind synonym gebrauchte Begriffe. Der Begriff leitet sich vom Bat ab, der Bezeichnung für das Schlagholz im.

Speakman argue that bats evolved nocturnality during the early and middle Eocene period to avoid predators. Among ectoparasites , bats carry fleas and mites , as well as specific parasites such as bat bugs and bat flies Nycteribiidae and Streblidae.

White nose syndrome is a condition associated with the deaths of millions of bats in the Eastern United States and Canada.

The fungus is mostly spread from bat to bat, and causes the disease. Bats are natural reservoirs for a large number of zoonotic pathogens , [] including rabies , endemic in many bat populations, [] [] [] histoplasmosis both directly and in guano, [] Nipah and Hendra viruses , [] [] and possibly the ebola virus.

Compared to rodents, bats carry more zoonotic viruses per species, and each virus is shared with more species. Some bats lead solitary lives, while others live in colonies of more than a million.

This may serve to introduce young to hibernation sites, signal reproduction in adults and allow adults to breed with those from other groups. Several species have a fission-fusion social structure , where large numbers of bats congregate in one roosting area, along with breaking up and mixing of subgroups.

Within these societies, bats are able to maintain long term relationships. Bats are among the most vocal of mammals and produce calls to attract mates, find roost partners and defend resources.

These calls are typically low-frequency and can travel long distances. Males sing to attract females.

Songs have three phrases: Bat songs are highly stereotypical but with variation in syllable number, phrase order, and phrase repetitions between individuals.

Calls differ between roosting groups and may arise from vocal learning. The animals made slightly different sounds when communicating with different individual bats, especially those of the opposite sex.

Bats in flight make vocal signals for traffic control. Greater bulldog bats honk when on a collision course with each other.

Bats also communicate by other means. Male little yellow-shouldered bats Sturnira lilium have shoulder glands that produce a spicy odour during the breeding season.

Like many other species, they have hair specialised for retaining and dispersing secretions. Such hair forms a conspicuous collar around the necks of the some Old World megabat males.

Male greater sac-winged bats Saccopteryx bilineata have sacs in their wings in which they mix body secretions like saliva and urine to create a perfume that they sprinkle on roost sites, a behaviour known as "salting".

Salting may be accompanied by singing. Most bat species are polygynous , where males mate with multiple females.

Male pipistrelle, noctule and vampire bats may claim and defend resources that attract females, such as roost sites, and mate with those females.

Males unable to claim a site are forced to live on the periphery where they have less reproductive success. For temperate living bats, mating takes place in late summer and early autumn.

In hibernating species, males are known to mate with females in torpor. Females of some species have delayed fertilisation, in which sperm is stored in the reproductive tract for several months after mating.

Mating occurs in the autumn but fertilisation does not occur until the following spring. Other species exhibit delayed implantation , in which the egg is fertilised after mating, but remains free in the reproductive tract until external conditions become favourable for giving birth and caring for the offspring.

During the delayed development the mother keeps the fertilised egg alive with nutrients. This process can go on for a long period, because of the advanced gas exchange system.

For temperate living bats, births typically take place in May or June in the northern hemisphere; births in the southern hemisphere occur in November and December.

Tropical species give birth at the beginning of the rainy season. The young emerges rear-first, possibly to prevent the wings from getting tangled, and the female cradles it in her wing and tail membranes.

In many species, females give birth and raise their young in maternity colonies and may assist each other in birthing. Most of the care for a young bat comes from the mother.

In monogamous species, the father plays a role. Allo-suckling, where a female suckles another mother's young, occurs in several species.

This may serve to increase colony size in species where females return to their natal colony to breed. For the little brown bat, this occurs about eighteen days after birth.

Weaning of young for most species takes place in under eighty days. The common vampire bat nurses its offspring beyond that and young vampire bats achieve independence later in life than other species.

This is probably due to the species' blood-based diet, which is difficult to obtain on a nightly basis. The maximum lifespan of bats is three-and-a-half times longer than other mammals of similar size.

Five species have been recorded to live over 30 years in the wild: One hypothesis consistent with the rate-of-living theory links this to the fact that they slow down their metabolic rate while hibernating ; bats that hibernate, on average, have a longer lifespan than bats that do not.

Bat species that give birth to multiple pups generally have a shorter lifespan than species that give birth to only a single pup.

Cave-roosting species may have a longer lifespan than non-roosting species because of the decreased predation in caves. A male Brandt's bat was recaptured in the wild after 41 years, making it the oldest known bat.

Groups such as the Bat Conservation International [] aim to increase awareness of bats' ecological roles and the environmental threats they face.

In the United Kingdom, all bats are protected under the Wildlife and Countryside Acts , and disturbing a bat or its roost can be punished with a heavy fine.

Many people put up bat houses to attract bats. The gates are designed not to limit the airflow, and thus to maintain the cave's micro-ecosystem.

Bats are eaten in countries across Asia and the Pacific Rim. In some cases, such as in Guam, flying foxes have become endangered through being hunted for food.

In many cultures, including in Europe, bats are associated with darkness, death, witchcraft, and malevolence. In Tanzania, a winged batlike creature known as Popobawa is believed to be a shapeshifting evil spirit that assaults and sodomises its victims.

More positive depictions of bats exist in some cultures. In China, bats have been associated with happiness, joy and good fortune.

Five bats are used to symbolise the "Five Blessings": The Weird Sisters in Shakespeare's Macbeth used the fur of a bat in their brew.

The bat is a primary animal associated with fictional characters of the night, both villainous vampires , such as Count Dracula and before him Varney the Vampire , [] and heroes , such as Batman.

The bat is sometimes used as a heraldic symbol in Spain and France, appearing in the coats of arms of the towns of Valencia , Palma de Mallorca , Fraga , Albacete , and Montchauvet.

Texas and Oklahoma are represented by the Mexican free-tailed bat, while Virginia is represented by the Virginia big-eared bat Corynorhinus townsendii virginianus.

Insectivorous bats in particular are especially helpful to farmers, as they control populations of agricultural pests and reduce the need to use pesticides.

This also prevents the overuse of pesticides, which can pollute the surrounding environment, and may lead to resistance in future generations of insects.

Bat dung, a type of guano , is rich in nitrates and is mined from caves for use as fertiliser. The Congress Avenue Bridge in Austin, Texas , is the summer home to North America's largest urban bat colony, an estimated 1,, Mexican free-tailed bats.

About , tourists a year visit the bridge at twilight to watch the bats leave the roost. From Wikipedia, the free encyclopedia.

Western Bat Species Custom link to a related page. Eumops perotis greater mastiff bat Distribution Eumops perotis, a member of the Family Molossidae, has a disjunct distribution, with two subspecies confined to South America.

The subspecies that occurs in North America, E. Recent surveys have extended the previously known range to the north in both Arizona several localities near the Utah border and California to within a few miles of the Oregon border.

Distribution in Nevada and Southern Utah is not well understood. Until recently, Nevada records were limited to a single record from Southern Nevada.

A recent study in southern Nevada has acoustic records for E. The species has also been detected acoustically in southern Utah. Published information suggests that the species occurs only to m in California, and 1, m in Texas.

Acoustic records of E. Recent surveys in northern Arizona have documented roosts at approx. The distribution of E. It is found in a variety of habitats, from desert scrub to chaparral to oak woodland and into the ponderosa pine belt and high elevation meadows of mixed conifer forests.

Global Rank — G5. National Rank — N3. While it may overlap somewhat in size with the smaller Eumops underwoodi, the tragus is broad and square in E.

It has also been found in similar crevices in large boulders and buildings. Although maternity roosts for many bat species contain only adult females and their young, some E.

Roosts are generally high above the ground, usually allowing a clear vertical drop of at least 3 m below the entrance for flight. In California, it is most frequently encountered in broad open areas.

Its foraging habitat includes dry desert washes, flood plains, chaparral, oak woodland, open ponderosa pine forest, grassland, and agricultural areas.

In northern Arizona, it is also encountered in broad open areas, and captures are limited to larger bodies of water. Its foraging habitats are similar to those described for California, but it also includes high elevation meadows surrounded by mixed conifer forests.

In Arizona, large Lepidoptera up to 60 mm pre-dominated for prey species, although a few small about 8 mm hymenopterous insects were consumed.

Studies in California and Arizona seem to indicate that they emerge from roosts just after dark. Unlike vespertilionids which mate in the fall, North American molossids, including E.

Available data suggest that, although most E. Unlike some Molosside species e. It does not undergo prolonged hibernation, and appears to be periodically active all winter, and thus may seek winter refugia that are protected from prolonged freezing temperatures.

Acoustic monitoring is transforming our understanding of this species, especially foraging habitat and species distributions. These strong, fast fliers cover an extensive foraging area and can be detected flying throughout the night.

The species appears to forage over open areas, and many individuals have been heard feeding over agricultural fields in the Imperial Valley and along the Lower Colorado River.

The species has been heard in open desert, at least 15 miles from the nearest possible roosting site Vaughan, Often multiple animals are detected together, and this species may travel or forage in groups.

Western mastiff bats move relatively short distances seasonally. Although capable of lowering their body temperatures for short periods of time, they do not undergo prolonged hibernation, and may be periodically active throughout the winter.

In California and Arizona, E. Like most other North American species of bat, the long term persistence of E. Population trends for this species are difficult to assess in many areas because of an absence of historical roost records.

When colonies are within or in close proximity to human dwellings, they are vulnerable to disturbance, vandalism and the hysteria which often surrounds bat colonies, causing extermination by pest control operators and public health departments.

Two colonies in buildings in the Los Angeles area Norco and Rancho Cucamonga were eradicated recently in the name of public health.

Any construction activities e. Rock climbing may also disturb roosting bats, and is a rapidly-growing recreational activity in the range of Eumops.

Communication with avid rock climbers suggest bat encounters do occur on climbs, and that hands or temporary climbing aids inserted into a roost crevice could cause abandonment of a site.

Non-chemical methods, such as the lepidopteron-attacking E. In general, the long term persistence of North American bat species is threatened by the loss of clean, open water; modification or destruction of roosting and foraging habitat; and, for hibernating species, disturbance or destruction of hibernacula.

Because of low fecundity, high juvenile mortality, and long generational turnover, many bat populations may be vulnerable to human-induced pressures.

Most roosts are in cliffs and are highly inaccessible; quite frequently in building roosts. Effectiveness of netting varies regionally. Flight is distinctive except in areas of overlap with E.

More surveys are needed, using acoustic techniques, to delineate the range of this species. More information is needed on distribution of breeding colonies, seasonal movements, roosting and foraging requirements.

Methods need to be developed for assessment and on going monitoring of population size. Heritage Data Management System: The subspecies found in Arizona, E.

It is found in sonoran desert habitat in Arizona, and has been found in pine-oak forest at 1,, m elevation in Mexico. Global Rank — G4.

Although this species can be predictably encountered at at least one locality in Arizona, its status and distribution are not well understood.

A former category 2 candidate species. Eumops species have a smooth upper lip, in contrast to a wrinkled upper lip in Nyctinomops.

No information is available on colony size. Based on limited samples, the diet of E. No information is available on seasonal movements.

No threats have been identified. Assuming that this species is primarily cliff-dwelling, it could be threatened by any activities that disturb or destroy cliff habitat e.

Grazing and pesticide applications in agricultural areas could impact foraging habitat. More surveys are needed to delineate the range of this species in the southwestern U.

Call features need to be described to determine whether this species can be distinguished from other large molossids acoustically.

University of Kentucky Press, Lexington, Ky. The species is thought to be non-migratory. The known altitudinal distribution is from near sea level to about 7, ft 2, meters.

Breeding ppopulations have recently been identified in southern California. This species currently is not listed as Threatened or Endangered.

It is a Species of Special Concern in California. There are no studies that elucidate the global population status of this species.

Rankings should be re-evaluated as more information is available. With a forearm of mm. It is slightly larger than T. The pocketed free-tailed bat is colonial and roosts primarily in crevices of rugged cliffs, high rocky outcrops and slopes.

It has been found in a variety of plant associations, including desert shrub and pine-oak forests. The species may also roost in buildings, caves, and under roof tiles.

The species forms maternity colonies, and females bear 1 young in late June or July. Lactating females have been taken between 7 July and 8 August, and volant juveniles recorded on 7 August.

Owls and snakes have been documented preying on this species. Little is known about population dynamics, seasonal movements, or ecology.

No known treats to the species have been identified to date. However, some of the general threats to bats could apply to N. These could include impacts to foraging areas from grazing, riparian management, the use of pesticides, and in some places disturbance to roost sites.

Information is needed on N. Little appears to be known about the echolocation calls of this species, and documentation is needed for comparison with other molossid species.

More information on the ecology of this species is required before threats can be more fully delineated. The bats of Texas.

University of Texas Press, Austin. Account by Kirk Navo. Distribution Nyctinomops macrotis, a member of the Family Molossidae, ranges from most of South America northward to include Mexico, Arizona, New Mexico, southern and western Texas, southern California and southeastern Nevada, southern Utah, and north to central Colorado.

The species is migratory, and there are some extralimital records from British Columbia, Iowa, Kansas, and South Carolina.

The known elevational range is from near sea level to about 8, ft 2, meters. The Big-free-tailed bat was proposed as a federal candidate C2 species in With an adult forearm of mm it is larger than T.

Also, it has dvertical grooves or wrinkles on the upper lip, which are lacking in Eumops. It has been found in a variety of plant associations, including desert shrub, woodlands, and evergreen forests.

It appears to be associated with lowlands, but has been documented at around 8, ft in New Mexico. This species is a seasonal migrant, and a powerful flyer.

It roosts mainly in the crevices of rocks in cliff situations, although there is some documentation of roosting in buildings, caves, and tree cavities.

The species forms maternity colonies, and females bear one young in late spring or early summer. Lactating females have been taken in July, August and September, and volant juveniles recorded on 8 and 27 August.

The use of pesticides in date-palm and other orchards may also constitute a threat to both roosting bats and the insects upon which they forage. Proceedings of the Royal Society B. Distribution Lasiurus cinereus, a member of the Family Vespertilionidae, is the most widespread of all North American bats. Bats are very essential to pollination and also insect remediation. The fungus is mostly spread from bat to bat, and causes the rueda de casino cuba.

This may have been used at first mainly to forage on the ground for insects and map out their surroundings in their gliding phase, or for communicative purposes.

After the adaptation of flight was established, it may have been refined to target flying prey by echolocation.

Bats are placental mammals. Around twenty years later, the German naturalist Johann Friedrich Blumenbach gave them their own order, Chiroptera.

Microbats use echolocation for navigation and finding prey, but megabats apart from those in the genus Rousettus do not, relying instead on their eyesight.

The following classification from Agnarsson and colleagues in reflects the traditional division into megabat and microbat suborders. The head and teeth shape of bats can vary by species.

In general, megabats have longer snouts, larger eye sockets and smaller ears, giving them a more dog-like appearance, which is the source of their nickname of "flying foxes".

Small insect-eating bats can have as many as 38 teeth, while vampire bats have only Bats that feed on hard-shelled insects have fewer but larger teeth with longer canines and more robust lower jaws than species that prey on softer bodied insects.

In nectar-feeding bats, the canines are long while the cheek-teeth are reduced. In fruit-eating bats, the cusps of the cheek teeth are adapted for crushing.

The upper incisors of vampire bats lack enamel , which keeps them razor-sharp. Bats are the only mammals capable of sustained flight, as opposed to gliding , as in the flying squirrel.

The finger bones of bats are much more flexible than those of other mammals, owing to their flattened cross-section and to low levels of calcium near their tips.

The elongation of bat digits, a key feature required for wing development, is due to the upregulation of bone morphogenetic proteins Bmps.

During embryonic development , the gene controlling Bmp signalling, Bmp2 , is subjected to increased expression in bat forelimbs—resulting in the extension of the manual digits.

This crucial genetic alteration helps create the specialised limbs required for powered flight. The relative proportion of extant bat forelimb digits compared with those of Eocene fossil bats have no significant differences, suggesting that bat wing morphology has been conserved for over 50 million years.

The wing bones of bats have a slightly lower breaking stress point than those of birds. As in other mammals, and unlike in birds, the radius is the main component of the forearm.

Bats have five elongated digits, which all radiate around the wrist. The thumb points forward and supports the leading edge of the wing, and the other digits support the tension held in the wing membrane.

The second and third digits go along the wing tip, allowing the wing to be pulled forward against aerodynamic drag , without having to be thick as in pterosaur wings.

The fourth and fifth digits go from the wrist to the trailing edge , and repel the bending force caused by air pushing up against the stiff membrane.

The wings of bats are much thinner and consist of more bones than the wings of birds, allowing bats to manoeuvre more accurately than the latter, and fly with more lift and less drag.

These sensitive areas are different in bats, as each bump has a tiny hair in the centre, making it even more sensitive and allowing the bat to detect and adapt to changing airflow; the primary use is to judge the most efficient speed to fly at, and possibly also to avoid stalls.

The patagium is the wing membrane; it is stretched between the arm and finger bones, and down the side of the body to the hind limbs and tail. This skin membrane consists of connective tissue , elastic fibres , nerves , muscles , and blood vessels.

The muscles keep the membrane taut during flight. The patagium is an extremely thin double layer of epidermis; these layers are separated by a connective tissue centre, rich with collagen and elastic fibres.

The membrane has no hair follicles or sweat glands, except between the fingers. To achieve flight, a bat exerts force inwards at the points where the membrane meets the skeleton, so that an opposing force balances it on the wing edges perpendicular to the wing surface.

This adaptation does not permit bats to reduce their wingspans, unlike birds, which can partly fold their wings in flight, radically reducing the wing span and area for the upstroke and for gliding.

Hence bats cannot travel over long distances as birds can. Nectar- and pollen-eating bats can hover, in a similar way to hummingbirds. The sharp leading edges of the wings can create vortices , which provide lift.

The vortex may be stabilised by the animal changing its wing curvatures. When not flying, bats hang upside down from their feet, a posture known as roosting.

The ankle joint can flex to allow the trailing edge of the wings to bend downwards. This does not permit many movements other than hanging or clambering up trees.

This difference is reflected in the structure of the cervical or neck vertebrae in the two groups, which are clearly distinct. Muscular power is needed to let go, but not to grasp a perch or when holding on.

Bats have an efficient circulatory system. They seem to make use of particularly strong venomotion, a rhythmic contraction of venous wall muscles.

In most mammals, the walls of the veins provide mainly passive resistance, maintaining their shape as deoxygenated blood flows through them, but in bats they appear to actively support blood flow back to the heart with this pumping action.

Bats possess a highly adapted respiratory system to cope with the demands of powered flight, an energetically taxing activity that requires a large continuous throughput of oxygen.

In bats, the relative alveolar surface area and pulmonary capillary blood volume are larger than in most other small quadrupedal mammals.

It takes a lot of energy and an efficient circulatory system to work the flight muscles of bats. Energy supply to the muscles engaged in flight require about double the amount compared to the muscles that do not use flight as a means of mammalian locomotion.

In parallel to energy consumption, blood oxygen levels of flying animals are twice as much as those of their terrestrially locomoting mammals. As the blood supply controls the amount of oxygen supplied throughout the body, the circulatory system must respond accordingly.

Therefore, compared to a terrestrial mammal of the same relative size, the bat's heart can be up to three times larger, and pump more blood.

With its extremely thin membranous tissue, a bat's wing can significantly contribute to the organism's total gas exchange efficiency.

When the bat has its wings spread it allows for an increase in surface area to volume ratio. The digestive system of bats has varying adaptations depending on the species of bat and its diet.

As in other flying animals, food is processed quickly and effectively to keep up with the energy demand. Insectivorous bats may have certain digestive enzymes to better process insects, such as chitinase to break down chitin , which is a large component of insects.

Nectivorous and frugivorous bats have more maltase and sucrase enzymes than insectivorous, to cope with the higher sugar contents of their diet.

The adaptations of the kidneys of bats vary with their diets. Carnivorous and vampire bats consume large amounts of protein and can output concentrated urine ; their kidneys have a thin cortex and long renal papillae.

Frugivorous bats lack that ability and have kidneys adapted for electrolyte -retention due to their low-electrolyte diet; their kidneys accordingly have a thick cortex and very short conical papillae.

Bats have higher metabolic rates associated with flying, which lead to an increased respiratory water loss. Their large wings are composed of the highly vascularized membranes, increasing the surface area, and leading to cutaneous evaporative water loss.

They are also susceptible to blood urea poisoning if they do not receive enough fluid. The structure of the uterine system in female bats can vary by species, with some having two uterine horns while others have a single mainline chamber.

Microbats and a few megabats emit ultrasonic sounds to produce echoes. By comparing the outgoing pulse with the returning echoes, the brain and auditory nervous system can produce detailed images of the bat's surroundings.

This allows bats to detect, localise, and classify their prey in darkness. Bat calls are some of the loudest airborne animal sounds, and can range in intensity from 60 to decibels.

The latter is most pronounced in the horseshoe bats Rhinolophus spp. In low-duty cycle echolocation, bats can separate their calls and returning echoes by time.

They have to time their short calls to finish before echoes return. Bats contract their middle ear muscles when emitting a call, so they can avoid deafening themselves.

The time interval between the call and echo allows them to relax these muscles, so they can hear the returning echo.

In high-duty cycle echolocation, bats emit a continuous call and separate pulse and echo in frequency. The ears of these bats are sharply tuned to a specific frequency range.

They emit calls outside this range to avoid deafening themselves. They then receive echoes back at the finely tuned frequency range by taking advantage of the Doppler shift of their motion in flight.

The Doppler shift of the returning echoes yields information relating to the motion and location of the bat's prey. These bats must deal with changes in the Doppler shift due to changes in their flight speed.

They have adapted to change their pulse emission frequency in relation to their flight speed so echoes still return in the optimal hearing range.

In addition to echolocating prey, bat ears are sensitive to the fluttering of moth wings, the sounds produced by tymbalate insects, and the movement of ground-dwelling prey, such as centipedes and earwigs.

The complex geometry of ridges on the inner surface of bat ears helps to sharply focus echolocation signals, and to passively listen for any other sound produced by the prey.

These ridges can be regarded as the acoustic equivalent of a Fresnel lens , and exist in a large variety of unrelated animals, such as the aye-aye , lesser galago , bat-eared fox , mouse lemur , and others.

By repeated scanning, bats can mentally construct an accurate image of the environment in which they are moving and of their prey.

Many moth species have a hearing organ called a tympanum , which responds to an incoming bat signal by causing the moth's flight muscles to twitch erratically, sending the moth into random evasive manoeuvres.

The eyes of most microbat species are small and poorly developed, leading to poor visual acuity , but no species is blind. Microbats may use their vision for orientation and while travelling between their roosting grounds and feeding grounds, as echolocation is only effective over short distances.

Some species can detect ultraviolet UV. As the bodies of some microbats have distinct coloration, they may be able to discriminate colours.

Megabat species often have eyesight as good as, if not better than, human vision. Their eyesight is adapted to both night and daylight vision, including some colour vision.

Microbats make use of magnetoreception , in that they have a high sensitivity to the Earth's magnetic field , as birds do. Microbats use a polarity-based compass, meaning that they differentiate north from south, unlike birds, which use the strength of the magnetic field to differentiate latitudes , which may be used in long-distance travel.

The mechanism is unknown but may involve magnetite particles. Most bats are homeothermic having a stable body temperature , the exception being the vesper bats Vespertilionidae , the horseshoe bats Rhinolophidae , the free-tailed bats Molossidae , and the bent-winged bats Miniopteridae , which extensively use heterothermy where body temperature can vary.

The wings are filled with blood vessels, and lose body heat when extended. At rest, they may wrap their wings around themselves to trap a layer of warm air.

Smaller bats generally have a higher metabolic rate than larger bats, and so need to consume more food in order to maintain homeothermy. Bats may avoid flying during the day to prevent overheating in the sun, since their dark wing-membranes absorb solar radiation.

Bats may not be able to dissipate heat if the ambient temperature is too high; [95] they use saliva to cool themselves in extreme conditions.

Bats also possess a system of sphincter valves on the arterial side of the vascular network that runs along the edge of their wings.

When fully open, these allow oxygenated blood to flow through the capillary network across the wing membrane; when contracted, they shunt flow directly to the veins, bypassing the wing capillaries.

This allows bats to control how much heat is exchanged through the flight membrane, allowing them to release heat during flight. Many other mammals use the capillary network in oversized ears for the same purpose.

Torpor , a state of decreased activity where the body temperature and metabolism decreases, is especially useful for microbats, as they use a large amount of energy while active, depend upon an unreliable food source, and have a limited ability to store fat.

Torpid states last longer in the summer for megabats than in the winter. During hibernation , bats enter a torpid state and decrease their body temperature for Heterothermic bats during long migrations may fly at night and go into a torpid state roosting in the daytime.

Unlike migratory birds, which fly during the day and feed during the night, nocturnal bats have a conflict between travelling and eating. The energy saved reduces their need to feed, and also decreases the duration of migration, which may prevent them from spending too much time in unfamiliar places, and decrease predation.

In some species, pregnant individuals may not use torpor. The smallest bat is Kitti's hog-nosed bat Craseonycteris thonglongyai , which is 29—34 millimetres 1.

Small prey may be absent in the diets of large bats as they are unable to detect them. Flight has enabled bats to become one of the most widely distributed groups of mammals.

Bat roosts can be found in hollows, crevices, foliage, and even human-made structures, and include "tents" the bats construct with leaves. In temperate areas, some microbats migrate hundreds of kilometres to winter hibernation dens; [] others pass into torpor in cold weather, rousing and feeding when warm weather allows insects to be active.

Different bat species have different diets, including insects, nectar, pollen, fruit and even vertebrates.

Insectivorous bats may eat over percent of their body weight, while frugivorous bats may eat over twice their weight. The Chiroptera as a whole are in the process of losing the ability to synthesise vitamin C.

Most microbats, especially in temperate areas, prey on insects. Fruit eating, or frugivory, is found in both major suborders.

Bats prefer ripe fruit, pulling it off the trees with their teeth. They fly back to their roosts to eat the fruit, sucking out the juice and spitting the seeds and pulp out onto the ground.

This helps disperse the seeds of these fruit trees, which may take root and grow where the bats have left them, and many species of plants depend on bats for seed dispersal.

Nectar-eating bats have acquired specialised adaptations. These bats possess long muzzles and long, extensible tongues covered in fine bristles that aid them in feeding on particular flowers and plants.

This is beneficial to them in terms of pollination and feeding. Their long, narrow tongues can reach deep into the long cup shape of some flowers.

When the tongue retracts, it coils up inside the rib cage. Around species of flowering plant rely on bat pollination and thus tend to open their flowers at night.

Some bats prey on other vertebrates, such as fish, frogs, lizards, birds and mammals. These bats locate large groups of frogs by tracking their mating calls, then plucking them from the surface of the water with their sharp canine teeth.

They use echolocation to detect small ripples on the water's surface, swoop down and use specially enlarged claws on their hind feet to grab the fish, then take their prey to a feeding roost and consume it.

A few species, specifically the common, white-winged , and hairy-legged vampire bats, only feed on animal blood hematophagy.

The common vampire bat typically feeds on large mammals such as cattle ; the hairy-legged and white-winged vampires feed on birds. Bats are subject to predation from birds of prey , such as owls , hawks , and falcons , and at roosts from terrestrial predators able to climb, such as cats.

Speakman argue that bats evolved nocturnality during the early and middle Eocene period to avoid predators.

Among ectoparasites , bats carry fleas and mites , as well as specific parasites such as bat bugs and bat flies Nycteribiidae and Streblidae.

White nose syndrome is a condition associated with the deaths of millions of bats in the Eastern United States and Canada. The fungus is mostly spread from bat to bat, and causes the disease.

Bats are natural reservoirs for a large number of zoonotic pathogens , [] including rabies , endemic in many bat populations, [] [] [] histoplasmosis both directly and in guano, [] Nipah and Hendra viruses , [] [] and possibly the ebola virus.

Compared to rodents, bats carry more zoonotic viruses per species, and each virus is shared with more species. Some bats lead solitary lives, while others live in colonies of more than a million.

This may serve to introduce young to hibernation sites, signal reproduction in adults and allow adults to breed with those from other groups. Several species have a fission-fusion social structure , where large numbers of bats congregate in one roosting area, along with breaking up and mixing of subgroups.

Within these societies, bats are able to maintain long term relationships. Bats are among the most vocal of mammals and produce calls to attract mates, find roost partners and defend resources.

These calls are typically low-frequency and can travel long distances. Males sing to attract females. Songs have three phrases: Bat songs are highly stereotypical but with variation in syllable number, phrase order, and phrase repetitions between individuals.

Calls differ between roosting groups and may arise from vocal learning. The animals made slightly different sounds when communicating with different individual bats, especially those of the opposite sex.

Bats in flight make vocal signals for traffic control. Greater bulldog bats honk when on a collision course with each other.

Bats also communicate by other means. Male little yellow-shouldered bats Sturnira lilium have shoulder glands that produce a spicy odour during the breeding season.

Like many other species, they have hair specialised for retaining and dispersing secretions. Such hair forms a conspicuous collar around the necks of the some Old World megabat males.

Male greater sac-winged bats Saccopteryx bilineata have sacs in their wings in which they mix body secretions like saliva and urine to create a perfume that they sprinkle on roost sites, a behaviour known as "salting".

Salting may be accompanied by singing. Most bat species are polygynous , where males mate with multiple females. Male pipistrelle, noctule and vampire bats may claim and defend resources that attract females, such as roost sites, and mate with those females.

Males unable to claim a site are forced to live on the periphery where they have less reproductive success.

For temperate living bats, mating takes place in late summer and early autumn. In hibernating species, males are known to mate with females in torpor.

Females of some species have delayed fertilisation, in which sperm is stored in the reproductive tract for several months after mating.

Mating occurs in the autumn but fertilisation does not occur until the following spring. Other species exhibit delayed implantation , in which the egg is fertilised after mating, but remains free in the reproductive tract until external conditions become favourable for giving birth and caring for the offspring.

During the delayed development the mother keeps the fertilised egg alive with nutrients. This process can go on for a long period, because of the advanced gas exchange system.

For temperate living bats, births typically take place in May or June in the northern hemisphere; births in the southern hemisphere occur in November and December.

Tropical species give birth at the beginning of the rainy season. The young emerges rear-first, possibly to prevent the wings from getting tangled, and the female cradles it in her wing and tail membranes.

In many species, females give birth and raise their young in maternity colonies and may assist each other in birthing.

Most of the care for a young bat comes from the mother. In monogamous species, the father plays a role. Allo-suckling, where a female suckles another mother's young, occurs in several species.

This may serve to increase colony size in species where females return to their natal colony to breed. For the little brown bat, this occurs about eighteen days after birth.

Weaning of young for most species takes place in under eighty days. The common vampire bat nurses its offspring beyond that and young vampire bats achieve independence later in life than other species.

This is probably due to the species' blood-based diet, which is difficult to obtain on a nightly basis. The maximum lifespan of bats is three-and-a-half times longer than other mammals of similar size.

Five species have been recorded to live over 30 years in the wild: One hypothesis consistent with the rate-of-living theory links this to the fact that they slow down their metabolic rate while hibernating ; bats that hibernate, on average, have a longer lifespan than bats that do not.

Bat species that give birth to multiple pups generally have a shorter lifespan than species that give birth to only a single pup. Cave-roosting species may have a longer lifespan than non-roosting species because of the decreased predation in caves.

A male Brandt's bat was recaptured in the wild after 41 years, making it the oldest known bat. Groups such as the Bat Conservation International [] aim to increase awareness of bats' ecological roles and the environmental threats they face.

In the United Kingdom, all bats are protected under the Wildlife and Countryside Acts , and disturbing a bat or its roost can be punished with a heavy fine.

Many people put up bat houses to attract bats. The gates are designed not to limit the airflow, and thus to maintain the cave's micro-ecosystem.

Bats are eaten in countries across Asia and the Pacific Rim. In some cases, such as in Guam, flying foxes have become endangered through being hunted for food.

In many cultures, including in Europe, bats are associated with darkness, death, witchcraft, and malevolence. In Tanzania, a winged batlike creature known as Popobawa is believed to be a shapeshifting evil spirit that assaults and sodomises its victims.

More positive depictions of bats exist in some cultures. In China, bats have been associated with happiness, joy and good fortune. Five bats are used to symbolise the "Five Blessings": The Weird Sisters in Shakespeare's Macbeth used the fur of a bat in their brew.

The bat is a primary animal associated with fictional characters of the night, both villainous vampires , such as Count Dracula and before him Varney the Vampire , [] and heroes , such as Batman.

The bat is sometimes used as a heraldic symbol in Spain and France, appearing in the coats of arms of the towns of Valencia , Palma de Mallorca , Fraga , Albacete , and Montchauvet.

Texas and Oklahoma are represented by the Mexican free-tailed bat, while Virginia is represented by the Virginia big-eared bat Corynorhinus townsendii virginianus.

Insectivorous bats in particular are especially helpful to farmers, as they control populations of agricultural pests and reduce the need to use pesticides.

This also prevents the overuse of pesticides, which can pollute the surrounding environment, and may lead to resistance in future generations of insects.

Bat dung, a type of guano , is rich in nitrates and is mined from caves for use as fertiliser. The Congress Avenue Bridge in Austin, Texas , is the summer home to North America's largest urban bat colony, an estimated 1,, Mexican free-tailed bats.

About , tourists a year visit the bridge at twilight to watch the bats leave the roost. From Wikipedia, the free encyclopedia.

Order of flying mammals. For other uses, see Bat disambiguation and Bats disambiguation. Be careful but thorough in checking the roof and chimney for bat guano droppings.

Also be on the lookout for Rub Marks made by bats entering and exiting the building. You are looking for a stained area that is yellowish brown to black brown in color, slightly sticky and will have a smooth polished appearance from high use.

You want to give the outside of the building or home a thorough look and then you want to inspect the attic and air conditioning pathways.

The attic inspection is imperative for a proper bat removal inspection. A professional bat inspector will be wearing a respirator to protect their lungs from inhaling potential disease carried by bat guano droppings.

These droppings will also help the professional bat removal expert determine the type of bats that are in the attic and help in the planning to do the bat removal humanely and protect the bat population from unnecessary harm.

The attic inspection will tell the United Bat Control expert the size of the bat colony and where they are living in the attic - and highlight where the bats are entering the building or house, be it the building's roof, chimney, the roofs edge or the knot hole around the attic window.

Bats leave their living quarters, their roost, at dusk for a night of flight and eating. They help the environment by eating millions of insects that are often harmful to human beings.

They carry seeds and help in pollinating flowers that benefit our ecology and environment. So usually our next step in our building and house inspection is to stand outside at dusk and observe the bats as they leave the building or home.

What one expert may have missed with the close hand inspection of the building is caught and supplemented by the United Bat Control expert in observing and following the bats leaving the roost.

Equipment for Removing Bats: The installation of patented bat exclusion devices is the next step in the process of removing bats from your commercial property, house or business.

During our dusk inspection and observation of the bats leaving your property, we determine whether one or more exclusion devices will best serve the needs of the bat colony.

Once the exclusion device locations are determined and the best number of exclusion devices to be used is determined, our bat control, bat removal professional will re-enter the house or business and install the device.

The installation of our patented One Way Bat Exclusion Device is done so that the entire bat colony will leave the building.

This is normally a one, two or three day process depending upon the size of the colony. Prior to, during and upon completion of the installation of the One Way Bat Removal Exclusion Device, it is imperative to patch up, repair and fix all of the cracks, slits, gaps and holes that were found during the bat removal inspection.

Once you have given the bats a way to get out the building, you do not want them to be able to return to your house or business. It is in the best interest of all parties to make sure that you seal the gaps permanently so that the bats are unable to return.

It is imperative for the health and safety of everyone who enters your business or home for a thorough cleaning of the building grounds, attic, roof and walls to remove bat guano.

Bat guano is a breeding ground for micro-organisms and in some cases will become a breeding ground for histoplasmosis, an infection that is able to cause harm to humans.

Bat guano can accumulate in walls, floors and ceilings. What is in plain site is not always the true amount of bat guano that needs to be removed from your home or business.

Important Information about Bat Rabies One must always be careful with bats and bat guano when they are found in your home and business.

There is always the possibility and potential that they are carrying rabies. Rabies is an infection that will affect human beings. We can get rabies from a bat if they are carrying rabies and they bite us.

It is imperative that if you have been bitten by a bat with rabies, you must get a vaccination within two 2 weeks of getting the bite because once you start getting sick it is fatal.

However, you do have 2 weeks to get a vaccination and if your dog, cat or horse has been bitten by a bat, there are vaccinations to protect them too.

It has been reported that during the past 20 years, there have been more human rabies cases that began with a bat bite in the United States than of any other wildlife group.

If you think you have bats in your home or business, call United Bat Control and let us come out and inspect the building.

You'll be glad you called a professional bat removal expert. We've been doing this since Bat Facts If you have a bat control problem with a single bat or a bat colony, United Bat Conrol can assist you in the removal of the bat in the most humane way possible.

We understand that bats are very important to our planet. We are doing everything in our control to make sure that once removed from a dwelling the bats are safe, healthy, find a new home and keep the ecological system balanced.

United Bat Control utilizes their patented devises that enables us to humanely exclude bat colonies numbering from a few in number to thousands in number!

After a proper exclusion is performed it is necessary to bat proof a structure so that the colonies cannot return. The ecological materials that are used to bat proof a structure are applied in a professional manner so as to conform to the aesthetics of your structure and the ecology of the community.

All accessible Guano should be removed. After a Guano clean-up is completed, it is recommended to have an application of a sterilizer and deodorizer provided.

This application is intended to kill the fungus that can cause Hystoplasmosis, as well as assist in providing a solution to the odor problem that is caused by bats and their colonies.

Never handle a dead animal without gloves and never attempt to clean up the bat mess they made without gloves because it could contain disease matter.

When you come across a live bat situation where you know they are in your house or business, give them a chance to leave quietly, rather than shout, scream or yell for them to get out of your home.

As professionals we have found that one of the most successful ways to make a bat leave is by installing a one way bat door over their entry and exit holes that they are using as front and back doors to your house and business.

Current News Bat News for November 1 Bat Week is a annual, international celebration and education of the role bats play throughout the natural world.

With more than 1, species of bats in the world, of which they are about 20 percent of all mammal species. About two-thirds of bats are insectivorous feeding on insects, worms, and other invertebrates..

They consume between 50 and percent of their own weight every night. What is the most amazing is that bats protect our food crops and timber industry.

With Bats eating these crop harmful bugs and insects farmers use less chemical pesticides than they do now.

A number of bat species pollinate many species of plants throughout the world, including agave, the main ingredient in tequila.

The bat guano feces is also valuable. Bat guano provides rich fertilizer across the landscape and is important for cave ecosystems.

Yes we need to learn more about bats an appreciate what they do for our ecosystem and environment. Bat News for October 15 Bats have always been seen in a less then appealing way.

From horror films to the batman. The new craze is Bat tourists. These Bat tourists are actually traveling the word to embark on a new kind of wildlife watching.

Bat tourism is a good thing which can help with bat conservation efforts. Under this bridge is up to 1. These bats form the largest urban bat colony in North America.

Crowds flock to the bridge to at dusk to see the bats swarm out for their nightly food flights. Bat News for October 1 Vampire bats are real.

Like most bats Vampire bats tend to live in colonies in almost completely dark places, such as caves, old wells, hollow trees, and buildings. They live in arid to humid, tropical and subtropical areas.

They hunt only when it is fully dark. The common vampire bat feeds primarily on the blood of mammals. They feed primarily on the blood of birds.

Bat News for September 15 Bats begin there hibernation in the late fall. It was once believed bats migrated to caves or mines for hibernation.

We now know many will hibernate inside homes and buildings. If the bats have a NEST in your home, they will return to the same corner, the same spot, year after year.

Bats live in walls and attic spaces because they make great places to hibernate or raise their young.

Bats can enter your home from gaps and cracks. Another way that they can enter your home is through loose or missing shingles or tiles.

Openings in the attic are an ideal invitation for bats to come inside to rest and nest. The big question what do you do? At United Bat Control were are professionals at bat removal from your home or business.

They will then remove the bat through Bat Exclusion which is the process of letting them fly out. The health of bat populations is a growing concern throughout the world.

Bats have recently experienced significant declines due to White-nose syndrome. White-nose syndrome is a fungus that has caused mass mortality several million deaths among hibernating bats throughout the northeast and mid-Atlantic states over the past several years.

Most people value bats as an important part of biodiversity and are keen to know more about their behavior and life history.

Bats Do Not get tangled up in long hair. Another myth is that most bats have rabies. It is rare to be bitten by a bat because they are shy and avoid people, biting only in self-defense if handled.

At United Bat Control we keep reminding the public of the beneficial role of bats in ecosystems around the world, and what can be done to protect them.

At United Bat Control we know if the bat needs to be tested or not for rabies. Our professional technicians will contact the county health department and follow their instructions.

We are here to help you with all of your bat control problems. Answer, most bats don t have rabies. Can you look at a bat and see they have rabies?

No you can t tell if it has rabies. Rabies can only be confirmed in a laboratory. Yes rabies is a fatal disease. The data shows that each year, tens of thousands of people are successfully protected from developing rabies through vaccination.

The fact is that ONLY their are one or two human rabies cases each year in the United States Also we know that the most common way for people to get rabies in the United States is through contact with a bat.

The data shows that people don't recognize the risk of rabies from the bite of a wild animal, particularly a bat, and they didn't seek medical advice.

United Bat Control wants to make you aware of the facts about bats and rabies and how you can protect your family, and pets.

Teach your children never to handle unfamiliar animals, wild or domestic. Wash any wound from an animal thoroughly with soap and water and seek medical attention immediately.
