Amazing Facts About the Common
Vampire Bat
- Vampire bats tend to live in
colonies in almost completely dark places, such as caves, old wells,
hollow trees, and buildings.
- These creatures are
nocturnal and most active in the early night.
- Vampire bats roost alone, in
small groups, or in colonies of thousands.
- The basic social structure
of roosting bats is made of ‘harems’. These are composed of females and
their offspring and a few adult males known as ‘resident males’ and a
separate group of males, known as ‘nonresident males’.
- Female vampire bats form
associations with one another that can last for many years.
- Vampire bats are believed to
be the only species of bats in the world to ‘adopt’ another young bat if
something happens to the bat’s mother.
They are very clean animals that frequently
groom themselves as well as other bats.
Vampire bats generally fly about one metre
off the ground.
Like the legendary monster from which they
get their name, these small mammals drink the blood of other animals for
survival.
They feed on blood from sleeping cows, pigs,
horses, and birds. Though uncommon, vampire bats occasionally bite humans for
blood.
Vampire bats have such good
eyesight that they may be able to see a cow from a distance of 130 metres.

- They don’t remove enough
blood to harm the animal, but their bites can cause nasty infections and
disease.
- Unlike some other species of
bats, vampire bats can walk, run, and jump. They have very strong hind
legs and a special thumb that helps them take off after feeding.
- Each night, vampire bats
drink about half of their body weight in blood.
- If they can’t find blood for
two nights in a row, they will die. Luckily, female bats can be generous;
well-fed bats will often regurgitate blood to share with others in
exchange for grooming.
- Vampire bats can actually be
quite tame, and even friendly to humans.
- Owls, eagles and hawks are
some of the vampire bat’s main predators.
- Rather than sucking blood,
vampire bats make a small cut with their teeth and then lap up the flowing
blood with their tongues.
- These bats are so light and
agile that they are sometimes able to drink blood from an animal for more
than 30 minutes without waking it up.
