For other uses, see Bat (disambiguation).For other uses, see Chiroptera (disambiguation).Their most distinguishing feature is that their forelimbs are developed as wings, making them the only mammals in the world naturally capable of flight (though other mammals, such as flying squirrels, gliding flying possums and colugos, can glide for limited distances).About 70 percent of bats are insectivores.Of the remainder, most feed on fruits and their juices.Phyllostomidae) of Central America and South America, and the two bulldog bat (Noctilionidae) species, which feed on fish.At least two species of bat are known to feed on other bats: the Spectral Bat, also called the American False Vampire bat, and the Ghost Bat of Australia.One species, the Greater Noctule bat, is believed to catch and eat small birds in the air.Some of the smaller bat species are important pollinators of some tropical flowers.Tenerife provides a recent example with the introduction of the Egyptian fruit bat.Despite the name, not all megabats are larger than microbats.The major distinction between the two suborders is based on other factors:
Microbats use echolocation, whereas megabats do not (except for Rousettus and relatives).The ears of microbats do not form a closed ring, but the edges are separated from each other at the base of the ear.Megabats eat fruit, nectar or pollen while microbats eat insects, blood (small quantities of the blood of animals), small mammals, and fish.Genetic evidence indicates that megabats should be placed within the four major lines of microbats (Yinochiroptera), who originated during the early Eocene.The same research also seems to support the view that the microbats are the original bats while megabats evolved from them independently through parallel evolution, where most of them lost the ability to use echolocation.There is some morphological evidence that Megachiroptera evolved flight separately from Microchiroptera.For example, the brains of megabats show a number of advanced characteristics linking these animals to primates, which have been deemed unlikely to have arisen by parallel evolution.Little hard evidence exists about the evolution of bats, since their small, delicate skeletons do not fossilize well.Bats are traditionally grouped with the tree shrews (Scandentia), colugos (Dermoptera), and the primates in superorder Archonta because of the similarities between Megachiroptera and these mammals.They have probably evolved for some time in New Guinea without microbat concurrention.This has resulted in some smaller megabats of the genus Nyctimene becoming (partly) insectivorous to fill the vacant microbat ecological niche.This is the process of echolocation, an ability they share with dolphins and whales.Noctuidae 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.Although the eyes of most microbat species are small and poorly developed, leading to poor visual acuity, it is incorrect to assume that they are nearly blind.The teeth of microbats resemble those of the insectivorans.They are very sharp in order to bite through the hardened armor of insects or the skin of fruits.The finger bones of bats are much more flexible than those of other mammals.The skin on their wing membranes is a lot more elastic and can stretch much more than is usually seen among mammals.Because their wings are much thinner than those of birds, bats can manoeuvre more quickly and more precisely than birds.The cells are concentrated in areas of the membrane where insects hit the wings when the bats capture them.Mother bats usually have only one offspring per year, and they are viviparous.Pups have even been seen to feed on other mothers' milk if their mother is dry.Young microbats become independent at the age of 6 to 8 weeks, megabats not until they are four months old.At the age of two years, bats are sexually mature.Many bats migrate, while others pass into torpor in cold weather but rouse themselves and feed when warm spells permit insect activity."Fusion" refers to the grouping of large numbers of bats in one roosting area and "fission" is the breaking apart and mixing of subgroups, with individual bats switching roosts with others and often ending up in different trees and with different roostmates.Many species also appear to have a high tolerance for harbouring pathogens and often do not develop disease while infected.Although one should not have an unreasonable fear of bats, one should avoid handling them or having them in one's living space, as with any wild animal.Bats have very small teeth and can bite a sleeping person without necessarily being felt.The bat should soon leave.Due to the risk of rabies and also due to health problems related to their faecal droppings (guano), bats should be excluded from inhabited parts of houses.In certain countries, such as the United Kingdom, it is illegal to handle bats without a license.The bat is sacred in Tonga and West Africa and is often considered the physical manifestation of a separable soul.Bats are closely associated with vampires, who are said to be able to shapeshift into bats, fog, or wolves.Bats are also a symbol of ghosts, death, and disease.Among some Native Americans, such as the Creek, Cherokee and Apache, the bat is a trickster spirit.The bat is also a heraldic animal of the Spanish autonomous community of Valencia.The Moche people depicted bats in their ceramics.The bat is a primary animal associated with fictional characters of the night, both villains like Dracula and heroes like Batman.In Sarawak, Malaysia bats are protected species under the Wildlife Protection Ordinance 1998 (see Malaysian Wildlife Law).Bats can be a tourist attraction.Artificial roosts
Many people put up bat houses to attract bats just like many people put up birdhouses to attract birds.In Britain, pillboxes dating from World War II have been converted to make roosts for bats.Tordo, AA Aquilar Setien (April 2000)."Isolation of Hendra virus from pteropid bats: a natural reservoir of Hendra virus"."Going to Bat", Scientific American, March 2006, pp.Note: This could be considered a lay summary of the various scientific publications cited in the preceding sentence."Twelve Common Questions About Human Rabies and Its Prevention" (PDF).United States since 1980 have been associated with bat rabies virus variants.Pillbox converted to bat retreat, BBC website.Pettigrew's summary on Flying Primate Hypothesis

Although a stick to hit a ball with is a somewhat simple concept, the bat is a complex object.It is carved or constructed very carefully to allow for a quick balanced swing, while providing power.The "barrel" is the thick part of the bat, where the bat is meant to hit the ball.The end of the barrel is not part of the sweet spot, and is simply called the tip or end of the bat.The billets, as they are now called, are inspected again for straightness of grain.The billets that arrive at the lumberyard are considered "green" wood because they still contain sap and gum.To achieve the proper seasoning, the billets are simply stacked in the yard for a period of six months to two years.The bat forms are sanded, inspected once more, and then sorted according to weight.The bat manufacturer keeps a model of each bat made, typically identified by the baseball player who initially ordered it.The plant workers who create the final product are called bat turners.The billet is placed on a lathe.All of the bats are then varnished, packed into cartons, and shipped to the player or team.Testing quality
The structural integrity of the baseball bats are monitored through repetitive impact testing.Inspectors collect data on the frequency of bending and how the balls travel off the bat.Recently there have been increasing numbers of "wooden bat leagues" and the trend back to wood seems to be accelerating on the grounds of safety concerns.Aesthetically, wooden bats are generally agreed to be superior to metal bats, both because of their more traditional appearance and because a ball hit with a wooden bat makes a loud "crack" sound, similar to a stone hitting a wooden fencepost while metal alloy bats have a "ping" sound, similar to the sound of a stone hitting an aluminum fencepost.Traditionally, ash trees from Pennsylvania and upstate New York are used to make baseball bats.The ash is valued for its strength, flexibility, and light weight.Hickory has fallen into disfavor because it is much heavier than other woods, while maple bats have become more popular recently.Only half of what is cut in the forest is ultimately used to manufacture baseball bats.R43 in the Louisville Slugger archives.Once the basic bat has been turned, it is then branded by burning, with the manufacturer's name, the serial number, and often the signature of the player for whom it was made: the brand is applied to the hard side of the bat, allowing the batter visual control of the hardness of the surface hitting the ball; the burn residue is then sanded off.The first player to endorse and sign a bat was Honus Wagner.Fungo bat
