An
Endangered Specie, Myotis Sodalis
Indiana Myotis
The Indiana myotis is a rather
nondescript small brown bat with a wingspan of about 9.5-10.5
inches. The bat is similar in appearance to the common little brown
myotis, but can be distinguished by the duller luster of its fur and toe
hairs that do not extend beyond the tips of the claws. This bat also has a
more pinkish colored nose. During hibernation Indiana bats
congregate in more densely packed clusters than other bats in its range.
This endangered specie hibernates in Organ Cave about 1/2 mile back into
the cave.

Eastern Pipistrelle
This is one of the common bats found in Organ Cave. It hangs in a
comma or like a half moon. It never hangs straight. It has an
orange tint forearm. The color of this bat is a dusty brown with a
lighter belly. It likes to be in the warmer parts of the cave,
especially while in hibernation. When this bat is in flight, it flaps
its wings about 16 times per second. Another interesting fact is that
it takes 100 pipistrelle bats to weigh 1 pound. This bat, to be so
small, gives birth to twins. The babies are called pups. They
feed on milk like all mammals. The mother carries them until
they are able to fly. The babies hang on to the mothers hair while
being carried. |

Myotis grisescens
Gray Bat
The
endangered gray bat spends the majority of its life inside of caves.
Unfortunately, human disturbance of its cave roosts has led to a severe
decline in this species’ population and the gray bat is now declared an
endangered species. With protection, the gray bat is making a come back
and its numbers are increasing. This southeastern bat can eat as many as
3,000 insects in a single night.

Plecotus townsendii
Townsend's big-eared Bat
Huge ears
assist this endangered, tan-colored bat in finding moths to eat. While
sleeping, the bat’s ears are coiled back and look very much like ram’s
horns. The base of the ear is crinkled, resembling the shape of an
accordion. Unfortunately, this bat resides near cave entrances and because
of this, it has suffered
greatly from human disturbance |

Bats are undoubtedly some of the most interesting animals on the planet.
Despite many misconceptions, they are not “rodents with wings”, but are an
entirely separate group of mammals. The scientific named used to designate
bats is “Chiroptera”, which means “hand-wing”. Bats do not actually have
wings in the sense that a bird does, but rather very long fingers with a
thin layer of skin (membrane) and muscle stretched between them. Bats are
the only mammals that are capable of true flight. Other mammals, such as
the flying squirrel, are only capable of gliding and cannot self sustain
their flight as a bat can. Like all mammals, bats are covered with a soft
coat of fur, bear live young and nurse them on milk. |
All
bats in Organ Cave are Micro bats. Bats are unusual animals, even
when teased they are among the least aggressive mammals on earth.
The bats tail membrane is used like a rudder, to help control direction.
Most bats are nocturnal, meaning they are primarily active at night.
Bats are the only flying mammal and they are not covered
with feathers like birds, but they are covered with hair. All bats
have the senses of sight, hearing and smell. Most bats use
echolocation after dark to fly and also to find their food. Sounds
are produced in the bats voice box or larynx. Most bats send out
sounds from their mouths, but others emit sound through their noses.
All microbats have the ability to echolocate. No two sonars are the
same among the nearly one thousand bat species.
Megabats cannot echolocate, except for the Rousettus
fruit bats, which produce clicks with the back of their tongues. |

There are nearly 1,000 species of bats in the world and one out of every
four mammal species is a species of bat. Approximately 40 species of bats
live in the United States, 13 of which have been accounted for in West
Virginia. Bats feed on a wide variety of foods, including fruit, pollen,
nectar, insects, frogs, fish, small mammals and even blood. All bats found
in West Virginia are insectivores, which is an animal that only
eats insects. Worldwide, bats range in size from weighing less than a dime
to having wingspans of over 6 feet. The largest bat found in West Virginia
has a wingspan of nearly 16 inches
Organ Cave is
home to thousands of bats. To date, 9 different species have been found in
and around Organ Cave. Among these are three endangered species: Virginia
Big-Eared, Indiana Bats and the Gray Bat; two rare species: Silver Haired and Small
Footed Bats; and four common species: Little Brown, Big Brown, Northern
Big Eared and Eastern Pipistrelle Bats.

The majority of bats in the United States spend the winter months
hibernating in caves, such as Organ Cave. This winter, the West Virginia
Department of Natural Resources conducted their annual bat count and
recorded over 2400 bats in the commercial section of the cave
alone.
Hibernating
bats often hang from the ceilings and walls of caves in clusters, but a
solitary hibernating bat is not an uncommon sight as well. Clusters of
bats may be as small as 2 or 3 bats or as large as hundreds of bats per
square foot, depending on the species of bat. The bat cluster pictured
above is the Indiana bat, which is an endangered species.
Bats are very social creatures. Many species of bats are known to assist
pregnant and nursing bats by gathering in clusters around these female
bats. The combined body heat of the cluster helps to keep young and
vulnerable bats warm and assist in their development.
Some species of bats move to trees or into the attics of building during
the summer and some bats live in caves all year round.

Little
brown bats grow very quickly. Around 18 days after birth, the young
bat is ready to fly. Within 3 weeks the bat pup loses its baby teeth
and grows new sharp ones for eating insects. Like their parents, the
babies must store as much fat as possible before winter hibernation.
A mother little brown can eat more than she weighs in bugs each night.
Her favorite bug dinner is the mosquito. Pictured to your
right is a cluster of full grown little brown bats.
In a bat nursery, the mother founds her pup by sound. Each baby has
a different sound that only the mother hears. |

Organ Cave's Big Brown Bat |
One of the
most commonly found bat at Organ Cave is the Big Brown Bat, which is the
largest in Organ Cave. These bats are among the most familiar bats to people in
the United States, as their large size and steady flight make them easily
recognized. The Big Brown Bat consumes beetles, ants, flies, mosquitoes,
mayflies, stoneflies and many other insects. One hundred fifty Big Browns can devour
millions of rootworms in a single growing season. They hunt insects
longer into the fall than do other bats and hibernate in caves during the
winter. The Big Brown Bat is commonly
found throughout the United States.

Nearly all bats in the United States and 70% of bats worldwide are
insectivores, which means they eat insects exclusively. Bats are the
only major predator of nocturnal flying insects. Bats often eat more than
50% of their body weight in insects each night and nursing female bats eat
enough insects to equal their body weight. This can result in a single bat
eating over 4,500 insects in a single night! Because bats eat so many
insects, they are a very important part of our ecosystem. |
|
While most
bats catch insects in their mouth, bats can also catch insects while
flying by scooping them into their tails or wing membranes. They can then
reach down and take these insects into their mouth while flying. Bats
drink by flying close to the surface of a body of water and gulp an
occasional mouthful.

The majority of bats in the United States eat insects, but bats in other
areas of the world eat a wide variety of things. Some bats eat nectar
and pollen from plants and flowers. These bats provide a valuable
service to the ecosystem because they function much like bees in helping
to pollinate plants. There are also bats that eat overly ripe fruit.
Because the fruit these bats eat is too ripe to sell, they are not a
problem for fruit growers. These bats provide a service to the ecosystem
by spreading fruit seeds, which helps new plants to grow.
A few
species of bats eat fish, which they catch by flying low over water and
grab the fish from the water with claws, much like birds of prey. A few
species also eat meat such as mice, birds, frogs, and even other bats.
The most famous and misunderstood bat is the vampire bat, which is found
in Mexico, Central America, and South America. The vampire bat feeds on
the blood of mammals and birds. These bats obtain blood by biting
animals, such as cattle, with their sharp incisor teeth and lap (not
suck) the blood from the wound. There is only one recorded sighting of a
vampire bat in the United States. This bat was discovered in a railroad
tunnel in Texas several years ago, 435 miles north of its usual home in
Mexico. |
