What
do you know about bats?

Although bats
are seldom seen in Wind Cave there are a few here and throughout
the area. Bats are shy creatures and want to avoid you as much as
you might want to avoid them.
Did
you know?
- Bats are
the only mammals that can fly.
- Bats are
NOT flying mice. Bats belong to a separate order of mammals called
Chiroptera.
- Bats come
in all different colors, shapes and varieties. Some are red, have
huge ears, or have very unusual faces. Many of these attributes
are related to their navigational system.
- One quarter
of all mammal species are bats. Worldwide there are almost a thousand
species of bats!
- In the US
alone there are 39 species of bats.
- In some parts
of the world, bats take the place of bees in pollinating plants.
- Little brown
bats have life spans that may exceed 32 years.
- A bat will
eat half it weight in insects in a single night.
How
do bats fly at night without crashing into things?

- In the 1930s
scientists discovered that bats use a kind of natural sonar that
allows them to "see" with their ears. This amazing system
is called echolocation.
- Most sounds
that a bat uses can not be heard by humans.
- A bat knows
where an insect is because the sounds bounce off of it and return
to the bat's ears. A bat can hear the footsteps of a walking insect!
- Most bats
send signals through their mouths, others use their noses.
- Not all bats
use echolocation. Fruit bats use sight and smell to locate their
food. All bats can see.
- Bats can
use echolocation even when there are distracting noises. Hundreds
of bats can fly out of a cave within range of one another's sound.
The Chinese view bats as symbols of good luck and happiness. They
symbolize health, long life, prosperity, love of virtue and natural
death.
Bat
Benefits
- A colony
of big brown bats can eat 18 million cucumber beetles.
- Plants such
as bananas, mangoes, cashews, dates and figs rely on bats for
pollination and seed dispersal.
- Tequila is
produced from agave plants. Seed production drops to 1/3000 of
normal without bat pollinators.
- Nectar-feeding
bats are primary pollinators of giant cacti such as the organ
pipe and saguaro.
- Bat droppings
(guano) support entire ecosystems of unique organisms, including
bacteria useful in detoxifying wastes, improving detergents and
producing gasohol and antibiotics.
Bats are in serious decline nearly everywhere. Forty percent of
the bats in the US and Canada are endangered or candidates for such
status. Even small disturbances in their habitat can seriously threaten
their survival.
Loss of plant and animal diversity may be the
most serious long-term global problem we face.
The relationships between insects, their predators,
and the plants they pollinate is tenuous. Disturbances with one
species can seriously change the balance in entire systems of plants
and animal life.
A
Bat House

| What
is a bat house? |
A
home for bats. |
| Why
have a bat house? |
Bats
are gentle, intelligent creatures. They pollinate plants and,
more importantly, eat insects. A little brown bat may eat 600
mosquitoes in an hour. They won't poison the environment and
they are cheaper than bug lights. |
| Where
should I put a bat house? |
Bats
like warm places to roost. So put it in a warm, sunny spot,
out of the wind. The best place is on the side of a building
about 10 to 15 feet above the ground. Most bats need to live
near water, preferably within a few hundred yards of a stream
or lake. |
For more information about bats, their conservation or building
a bat house contact Bat Conservation International.
Rabies
All 39 resident species of bats in the US are capable of being infected
with rabies, but the incidence of rabies is the same as in other
mammals. Only 10 people have contracted rabies from bats in more
than 30 years. When a bat contracts rabies, it becomes lethargic
and dies. This is unlike the aggressive behavior of some other mammals.
That is - if you see a sick bat or other
animal - leave it alone. In fact, it is best to leave all
wild creatures alone. Enjoy them by observing them, not by interacting
with them.
Left alone, bats pose no threat to humans.
