Now on to the Facts!
1.) The vampire bats like most other bats, are nocturnal (they’re awake during the night).
2.) They feed on blood from cows, pigs, horses, and birds. It isn’t common for them to bite humans for a blood meal.
3.) A vampire bat will use its sharp front teeth to make a small wound and then lap up the blood dripping from the open wound. Their victim has no idea the bat is even there, as special anesthetic spit numbs the area and has an anticoagulant that keeps blood flowing!
4.) Unlike other bats, vampire bats can walk, run, and even jump!
5.) These bats use a special heat receptor in their noses to find the best spot on their prey to land. The warmer the spot, the more blood flow.
But wait, there’s more on the vampire bat!
Did you know…?
After a female has a baby, it has been witnessed that other bats will feed the new mother for approximately 2 weeks.
8.) Like other bats, vampire bats sleep in total darkness during the day while hanging upside down. Bats have one way valves in their arteries to prevent the blood from flowing backwards. That’s why they are able to hang upside down without blood rushing to their heads.
9.) These bats typically gather in colonies of about 100 or so, but have been seen in groups of 1,000 or more!
10.) In just 1 year a vampire bat colony of around 100 bats can drink the blood from 25 cows.
