An uncontrollable, irrepressible fear of bats may
exist, but it is often the result of
centuries of prejudice, misinformation and ignorance about bats. The Dracula
and other horror stories have contributed greatly to these
misconceptions causing people to fear them and be unconcerned for
their conservation.
A
“Myth” is a commonly held belief, idea or explanation that is not
true.
Myths
arise from people’s need to make sense of things we do not understand
or have sufficient knowledge of. They attempt to explain unpleasant
events in ways that fit with our preconceived ideas about the world -
they arise from and reinforce our prejudices and stereotypes. Myths have
powerful implications for how we look at the world. Below we present
some common myths and illusions about bats.
Contain your phobia by
confronting the following deceptive myths!

True
or False |

Information |
All
bats are blind.
|
False |
All
bats can see, some see better than humans. The mega bats have
large eyes that enable them to see flowers and fruit in the night.
Smaller bats can see, but do rely on their ability to echolocate
for capturing insects and navigating in the dark.
|
Bats
will get tangled in your hair at night.
|
False |
Bats
do not want to be in anybody’s hair! Experiments have been done
placing bats in people's hair. The bats would not stay on
anybody's head. Even when long hair is wrapped around a bat it
will free itself and fly away.
|
Bats
are aggressive and will attack humans
|
False |
Bats
are shy, naturally gentle and not aggressive. Like any cornered
wild animal, bats may bite in self-defence when picked up
|
Bats
are related to mice and rats |
False |
Bats
are not rodents. They belong to the order of Chiroptera, which
means hand-winged. In number of species, Chiroptera is the second
largest group of mammals in the world. They are the only mammals
capable of true flight.
|
Bats
hibernate during winter |
True
|
Bats
can hibernate at will. If there is a food shortage due to weather
changes, bats can shut down their metabolism and sleep until
better times.
|
Bats
are covered with fine feathers |
False |
Bats
have fur. The amount varies, depending on the species and climatic
conditions. Some bats have long angora-like fur, ranging in colour
from bright red or yellow to jet-black or white.
One species is furless, and another even has pink wings and
ears. |
Bats
are mammals and drink mother’s milk during first weeks of life |
True |
Like
humans, bats give birth to poorly developed young and nurse them
from a pair of pectoral breasts. Mother bats have been known to
adopt each other's young. |
Bats
reproduce profusely – a mother may have 5 – 8 babies per year
|
False |
Whereas
mice have litters of baby mice several times during the year, most
bats usually give birth to one pup a year, and some do not
give birth until the pups are two or more years old, thus making
them the slowest reproducing mammals on earth for their size.
Sixty percent of bats do not survive infancy, so population
recovery is quite slow - for this and other reasons bat
populations are vulnerable to extinction.
|
According
to the type of bat, they either eat fruit, nectar, insects, fish,
frogs and small mammals like mice |
True |
Seventy
percent of all bat species eat insects; most of the remaining 30%
eat fruit, pollen and nectar. The False Vampire Bat of Central
America captures birds, other vertebrates and occasionally, other
species of bats by grabbing them by the neck and killing it with
one powerful bite. The Fisherman or Bulldog Bat of Central America
feeds on fish during the dry season but eats beetles and moths in
the rainy season. By echolocating, the Fringed-lipped Bat of
Central America can distinguish between a poisonous and a
non-poisonous frog, its main prey. |
|
Most
fruit eating bats do not echolocate. They find their food by sight
and smell. |
True |
Echolocation
is unique to bats and some species of dolphins and whales. It is
similar to common sonar, in which a sound is emitted by the bat and
bounces off insects or objects and returns to the bat's ears.
Echolocation enables bats to catch insects in flight.
Most
fruit eating bats do not echo locate. They find their foodby sight
and smell. Since they cannot navigate dark caves without echo
location, they commonly roost in tree hollows, on the bark itself,
or under leaves. Flying foxes simply hang in plain view.
|
The
squeaks and squawks bats make in their roost are echolocation
noises. |
False |
Most
of the high-frequency sounds emitted by bats for echolocation are
inaudible to humans, although bats also produce sounds that humans
can hear. These are mostly social calls. |
Vampire
bats do not exist – it is merely a myth |
False |
Of
the world's 1000 species, only three are vampire bats, limited
mostly to Central and South America. Vampire bats do not attack
humans. They are very small and they generally drink the blood of
animals and poultry. They do not actually suck blood, but rather
they make a small incision with razor sharp teeth and then lap up
the blood. Scientists are currently studying the saliva of these
bats to develop new anticoagulant drugs to prevent blood clots in
heart patients. |
Bats
are carriers of diseases, especially rabies |
False |
By
definition, a carrier is a person or animal that carries a disease
without being sick. Bats are not designated rabies carriers. They
contract and die from rabies much like humans, cats, and dogs do.
The odds that a person will die of a bat-borne disease are usually far less
than those of being killed by a dog, a bee sting, or of food
poisoning at a church picnic.
A
grounded bat should never be handled because it may bite in
self-defence. |
Bat
droppings are a dangerous source of lung diseases like tuberculosis |
False |
There
is no evidence to suggest that bats, or their droppings, called
"guano", transmit tuberculosis to man.
A
usually mild lung disease, Histoplasmosis, is caused by inhaling spores of
the fungus Histoplasma capsulatum, living in moist bird or
bat guano, mostly found in caves. |
Bats
are dirty and ridden with lice, ticks and fleas |
False |
Bats
need to keep themselves extremely clean to fly and therefore groom
themselves daily. They host no more parasites than other animals,
and parasites that do afflict bats are very specialized and rarely
pose problems to humans. |
The
biggest bat in the world has a 2 meter wingspan. |
True |
Some
of the fruit-eating flying foxes in Central America have wingspans
of almost 2m, and weigh up to 1.2kg. The world’s smallest mammal,
the hog-nosed Bat from Thailand, weighs only 2g. |
Bats
have no real benefits for people |
False |
Worldwide,
bats are the major predators of night-flying insects, including
mosquitoes and many crop pests.
An individual Mouse-eared Bat from North America can catch up
to 600 mosquitoes in an hour! Closer
to home, it has been estimated that the colony of 300,000 bats at De
Hoop Cave catch 100 tons of insects a year, including many crop
pests, thus providing an important service to farmers in the
Bredasdorp area.
Throughout
the tropics the seed dispersal and pollination activities of fruit-
and nectar-eating bats are vital to the survival of rain forests,
with some bats acting as ‘keystone’ species in the lives of
plants crucial to entire ecosystems and some of the world’s most
economically valuable crop plants such as wild bananas, breadfruit,
avocados, dates, figs, peaches and mangoes.
Studies
of bats have contributed to the development of navigational aids for
the blind, birth control and artificial insemination techniques,
vaccine production and drug testing, as well as to a better
understanding of low-temperature surgical procedures. |
When
bats are discovered in a house or office building, they should be
exterminated because they are a menace and carry diseases |
False |
With
increasing urbanisation, many bats have been forced to make use of
buildings as natural roost sites are destroyed or made unsuitable
for bats. Roof-roosting bats can sometimes be a nuisance in terms of
noise at night, the unpleasant odour of the guano and, in some
cases, the bats themselves. Unwelcome
Bats should never be killed, there are many safe ways in
which bats can be evicted, provided that alternative housing is
provided. |
Bat
houses in a residential neighbourhood will result in undesirable
amounts of bats flocking to that area, causing pollution and
nuisance to the other residents |
False |
Where
bat houses in a residential area are suitable and adequate for the
species in the area, bats would use them rather than roosting in
buildings. Bat houses
should always be used when evicting bats from a building.
Bats
in a residential area where mosquitos and other insects cause
problems, will considerably reduce their numbers. Farmers may wish to
attract bats to roost close to their crops and so aid the farmer in
insect and pest control. |
There
are more than 50 species of bats in South Africa |
True |
South
Africa has 56 recorded species of bats. Of the 74 species found in the
sub region of southern Africa, 20 species of insectivorous bats and 2
species of fruit-eating bats are listed as Threatened in the IUCN
Red List of threatened Animals. Of these, 9 are listed as either
Critically Endangered, Endangered or Vulnerable, meaning that they
face a high risk of extinction in the wild.
Worldwide,
the 977 species of bats make up a quarter of all mammal species. |
All
bats have ugly, terrifying looks! |
False |
Although
some may have odd-looking faces, many are truly pretty and cute! The
fruit bats or 'flying foxes' and vesper bats are quite adorable.
Please keep in mind that bats are equipped with
incredible anatomical and physiological adaptations for survival. The
diverse and elaborate facial features and ears of many insectivorous
bats are associated with echolocation.
Trust
us - the more you see them and learn about their amazing abilities,
the more appreciation and approval one develops for their features! |
Now that you know the truth
about bats, relax and enjoy their presence in nature. Contribute to their
conservation by dismissing the fears of others by educating them with the
true facts about bats!
