Feeding Habits
By: Shyan Chapman 03-22-2003
Vampire Bats once hunted wild animals, but now mainly feed on
domestic animals, Such as cattle, etc.
The Vampire Bat feeds on the blood of animals - Cows, Pigs and Horses
seem to be its' favorite forms of prey - though they seem to feed on Calves
more than Cows, probably due to the fact that Calves sleep for longer periods
of time.
When Cattle, or prey along the lines are not available, Bats will
usually attack smaller prey, like Turkeys and Chicken.
In a single year a colony of one hundred Vampire Bats consumes the
equivalent to the amount of blood in twenty five Cows.
Vampire Bats have also been known to feed on sleeping and
unsuspecting Humans.
The Bat will usually decide to feed upon the most docile or
isolated animal in the herd.
Using its' needle like incisor teeth, the Bat makes a small
incision in the animals skin - usually choosing a fleshy area, like a shoulder,
neck, or ear where the blood vessels are closer to the surface.
Chemicals found in the Bats saliva keep the blood from coagulating
keep the blood flowing for two to three minutes while the Bat feeds.
Often two, or more Bats will drink from the same incision made by
a single Bat.
A Bat makes use of its' tongue by lapping up blood into their
mouth.
The Bats' tongue has two lateral grooves, which alternately open
and close while the Bat is drinking - this action draws the blood up the deeply
grooved lower lip, channeling it into the mouth.
Often the host animal will feel no ill effects from the loss of
blood, however, if too many Bats feed off the same animal it may feel severely
weakened and the Bat can infect its' prey with rabies and other diseases.
A mature Vampire Bat will consume about five teaspoons of blood
accumulated throughout the day.
