The common vampire bat (Desmodus rotundus) is a small, leaf-nosed bat native to the Americas. It is one of three extant species of vampire bats, the other two being the hairy-legged and the white-winged vampire bats.
The common vampire bat practices hematophagy, mainly feeding on the blood of livestock. The bat usually approaches its prey at night while they are sleeping. It then uses its razor-sharp teeth to cut open the skin of its hosts and lap up their blood with its long tongue. The species is highly polygynous, and dominant adult males defend groups of females. It is one of the most social of bat species with a number of cooperative behaviors such as social grooming and food sharing. Because it feeds on livestock and is a carrier of rabies, the common vampire bat is considered a pest. Its conservation status is categorized as least concern by the International Union for Conservation of Nature because of "its wide distribution, presumed large population tolerance of a degree of habitat modification, and because it is unlikely to be declining at nearly the rate required to qualify for listing in a threatened category."
Taxonomy
The common vampire bat was first described as Phyllostoma rotundum by Étienne Geoffroy Saint-Hilaire in 1810.{{cite journal |last1=Geoffroy |first1=E. |title=Sur les Phyllostomes et les Mégadermes, deux Genres de la famille des Chauve-souris. |journal=Annales du Muséum d'histoire naturelle. |date=1810 |volume=15 |page=181 |url=https://biodiversitylibrary.org/page/3546866 |publisher=G.

Physical description
File:Vampire bat skeleton face.jpg
File:Common Vampire Bat Skull.jpg
The common vampire bat is short-haired, with silver-gray fur on its undersides, demarcated from the darker fur on its back. It has a deeply grooved lower lip, and a flat, leaf-shaped nose. A well-developed, clawed thumb on each wing is used to climb onto prey and to assist the animal in take-off. The bat averages about 9 cm (3.5 in) long with a wingspan of 18 cm (7 in). It commonly weighs about 25–40 grams (2 oz), but its weight can drastically increase after a single feeding.[http://socialbat.org/2015/08/31/foraging-vampire-bats-can-expect-big-meals-or-none-at-all/ Foraging vampire bats can expect big meals or none at all] {{Webarchive|url=https://web.archive.org/web/20150903233954/http://socialbat.org/2015/08/31/foraging-vampire-bats-can-expect-big-meals-or-none-at-all/ |date=2015-09-03 }}. socialbat.org (2015-08-31). The braincase is relatively large, but the snout is reduced to accommodate large incisors and canines. It has the fewest teeth among bats. The upper incisors lack enamel, which keeps them razor-sharp. Its dental formula is {{DentalFormula| upper=1.1.2.0|lower=1.1.3.0}}, for a total of 18 teeth.
While most other bats have almost completely lost the ability to maneuver on land, vampire bats are an exception.{{cite journal|author1=Riskin, Daniel K. |author2=Hermanson, John W. |year=2005|title= Biomechanics: Independent evolution of running in vampire bats|journal=Nature|volume= 434|issue=7031 |page=292|doi= 10.1038/434292a|pmid=15772640|bibcode=2005Natur.434..292R |s2cid=4406312 |doi-access=free}}[http://www.nature.com/nature/journal/v434/n7031/extref/434292a-s2.mov video] {{Webarchive|url=https://web.archive.org/web/20050923063156/http://www.nature.com/nature/journal/v434/n7031/extref/434292a-s2.mov |date=2005-09-23 }} They can run using a unique, bounding gait in which the forelimbs are used instead of the hindlimbs to propel forward, as the wings are much more powerful than the legs. This ability likely evolved independently within the bat lineage. Three pads under the thumb function like a sole. It is also capable of leaping in various directions, heights, and distances.Altenbach, J. S.

Common vampire bats have good eyesight. They are able to distinguish different optical patterns and may use vision for long-range orientation. These bats also have well-developed senses of smell and hearing: the cochlea is highly sensitive to low-frequency acoustics, and the nasal passages are relatively large. They emit echolocation signals orally, and thus fly with their mouths open for navigation.{{cite journal|vauthors=Schmidt U, Schmidt C |year=2007|title= Echolocation performance of the vampire bat (Desmodus rotundus)|journal= Zeitschrift für Tierpsychologie|volume= 45|issue= 4|pages=349–58|pmid= 610226|doi=10.1111/j.1439-0310.1977.tb02025.x}} They can identify a metal strip {{convert|1|cm}} wide at a distance of {{convert|50|cm}}, which is moderate compared to other bats.
Range and habitat
The common vampire bat is found in parts of Mexico, Central America, and South America, as well as the Caribbean islands of Margarita and Trinidad. They can be found as far north as {{convert|280|km}} south of the Mexico–United States border. Fossils of this species have been found in Florida and states bordering Mexico. The common vampire is the most common bat species in southeastern Brazil.{{cite journal|author=Trajano, E.|s2cid=52060593|year=1996|title= Movements of Cave Bats in Southeastern Brazil, With Emphasis on the Population Ecology of the Common Vampire Bat, Desmodus rotundus (Chiroptera)|journal= Biotropica|volume= 28|issue= 1|pages=121–29|jstor= 2388777|doi=10.2307/2388777}} The southern extent of its range is Uruguay, northern Argentina, and central Chile.

The common vampire bat feeds primarily on mammalian blood, particularly that of livestock such as cattle and horses. Vampire bats feed on wild prey like the tapir, but seem to prefer domesticated animals, and favor horses over cattle when given the choice.{{cite journal | author = Wilkinson G | year = 1990 | title = Food Sharing in Vampire Bats | url = http://facstaff.unca.edu/cnicolay/BIO379/wilkinson-foodsharing.pdf | journal = Scientific American | volume = 262 | issue = 21 | pages = 76–82 | access-date = 2011-09-11 | archive-url = https://web.archive.org/web/20120306140506/http://facstaff.unca.edu/cnicolay/BIO379/wilkinson-foodsharing.pdf | archive-date = 2012-03-06 | url-status = dead | doi = 10.1038/scientificamerican0290-76 | bibcode = 1990SciAm.262b..76W }} Female animals, particularly those in estrus, are more often targeted than males.

Vampire bats hunt at night, using echolocation and olfaction to track down prey.Wilkinson, J. (2001) "Bat Blood Donors", pp. 766-767 in The Encyclopedia of Mammals. Facts on File. Eds. D. MacDonald & S. Norris. {{ISBN|0-87196-871-1}} They feed in a distance of {{convert|5|to|8|km|abbr=on}} from their roosts.Nowak, R. M. (1991) Walker's Mammals of the World. pp. 1629. Johns Hopkins Press. {{ISBN|0-8018-3970-X}} When a bat selects a target, it lands on it, or jumps up onto it from the ground, usually targeting the rump, flank, or neck of its prey; heat sensors in the nose help it to detect blood vessels near the surface of the skin. It pierces the animal's skin with its teeth, biting away a small flap, and laps up the blood with its tongue, which has lateral grooves adapted to this purpose. The blood is kept from clotting by an anticoagulant in the saliva.
They are protective of their host and will fend off other bats while feeding. It is uncommon for two or more bats to feed on the same host, with the exception of mothers and their offspring.
=Mating and reproduction=
Male vampire bats guard roosting sites that attract females, but females often switch roosts. {{cite journal|author= Wilkinson, G. S.|year= 1985|title= The Social Organization of the Common Vampire Bat II: Mating system, genetic structure, and relatedness|journal= Behav. Ecol.

During estrus, a female releases one egg. Mating usually lasts three to four minutes; the male bat mounts the female from the posterior end, grasps her back with his teeth, holds down her folded wings, and inseminates her.{{cite web|author2=Anderson, Rebecca|author=Michael Mulheisen|title=Desmodus rotundus|url=http://animaldiversity.ummz.umich.edu/site/accounts/information/Desmodus_rotundus.html|publisher=Animal Diversity Web|access-date=December 16, 2011|archive-date=March 16, 2004|archive-url=https://web.archive.org/web/20040316085828/http://animaldiversity.ummz.umich.edu/site/accounts/information/Desmodus_rotundus.html|url-status=live}} Vampire bats are reproductively active year-round, although the number of conceptions and births peak in the rainy season. Females give birth to one offspring per pregnancy, following a gestation period of about seven months. The young are raised primarily by the females. Mothers leave their young to hunt, and call their young to feed upon returning. The young accompany their mothers to hunt at six months, but are not fully weaned until nine months. Female offspring usually remain in their natal groups into adulthood, unless their mothers die or move. The occasional movements of unrelated females between groups leads to the formation of multiple matrilines within groups. Male offspring tend to live in their natal groups until they are one to two years old, sometimes being forced out by the resident adult males.
=Cooperation=
File:Regurgitated food sharing in common vampire bats, Desmodus rotundus.jpg
Regurgitated food sharing in common vampire bats has been studied in both the lab and field, and is predicted by kinship, association, and reciprocal help {{cite journal|author1=Carter, GG |author2=Wilkinson, GSD |year=2013|title= Does food sharing in vampire bats demonstrate reciprocity?|journal= Comm Integ Biol |volume= 6|issue= 6|pmc=3913674|pmid=24505498|doi=10.4161/cib.25783|pages=e25783}} In a field study conducted in Costa Rica from 1978 to 1983, vampire bats frequently switched between several roost trees and co-roosted with kin and non-kin. Mean genetic kinship within roosting groups was low (r = 0.03 − 0.11), but 95% of food sharing observed in the wild occurred between close kin (first cousins or higher). Most observed food sharing (70%) was mothers feeding their pups. The non-maternal sharing events were kin-biased suggesting that vampire bats prefer to help relatives. However, non-maternal food sharing is even better explained by frequency of interaction, even after controlling for kinship. Food sharing was only observed when the co-roosting association was greater than 60%. Food sharing appears to require social bonds that require development over long periods of time. Among familiar bats, the amount of food given from bat A to bat B is best predicted by the amount of food given from bat B to A. Reciprocal sharing is most obvious over longer time spans as found in primate cooperation.
Vampire bats also participate in mutual grooming; two bats groom each other simultaneously to clean one another, and to strengthen social bonds.{{cite journal | author = Wilkinson G.

The highest occurrence of rabies in vampire bats occurs in the large populations found in South America. The danger is not so much to the human population, but rather to livestock.[http://www.si.edu/Encyclopedia_SI/nmnh/batfacts.htm Bat Facts] {{Webarchive|url=https://web.archive.org/web/20200728234208/https://www.si.edu/Encyclopedia_SI/nmnh/batfacts.htm |date=2020-07-28 }} Smithsonian. Retrieved 6 April 2011. Joseph Lennox Pawan, a government bacteriologist in Trinidad, found the first infected vampire bat in March 1932. He soon proved various species of bat, including the common vampire bat, are capable of transmitting rabies for an extended period of time without artificial infection or external symptoms.[http://www.niherst.gov.tt/icons/profiles/joseph-lennox-pawan.htm Joseph Lennox Pawan] {{Webarchive|url=https://web.archive.org/web/20160304095149/http://www.niherst.gov.tt/icons/profiles/joseph-lennox-pawan.htm |date=2016-03-04 }}, Caribbean Council for Science and Technology. Retrieved 1 April 2011 Fruit bats of the genus Artibeus were later shown to demonstrate the same abilities. During this asymptomatic stage, the bats continue to behave normally and breed. At first, Pawan's finding that bats transmitted rabies to people and animals were thought fantastic and were ridiculed.{{citation needed|date=January 2016}}
Although most bats do not have rabies, those that do may be clumsy, disoriented, and unable to fly, which makes them more likely to come into contact with humans. There is evidence that it is possible for the rabies virus to infect a host purely through airborne transmission, without direct physical contact of the victim with the bat.{{cite journal
