Pallid Bat
It is the time of year where bats come into the spotlight. Unfortunately there are a lot, and I mean a lot, misconceptions. I thought I'd take this opportunity to share information with you that you can pass on. All of these pictures are from my bat internship in Mesa Verde. Please do not copy them without giving credit (some of these are attributed to Ryan Choi).
1. Bats are not blind. Mega-bats (fruit bats and flying foxes), rely on their eyesight all of the time. Micro-bats (what we have in the U.S.) have small eyes that they use when they are not echo-locating.
Little Brown Bat
2. Most bats do not have rabies. It is estimated that 0.5% of all bats carry rabies. And when they have rabies they die soon after. However, never ever handle a bat with your bare hands. If you think you or somebody else has been bit, go to the doctor immediately. In the U.S. there is no reason to die. Once you start exhibiting symptoms there is no cure. The biggest spreader of rabies in the world are dogs.
Spotted Bat (or Skull Bat)
3. Bats don't need your hair, they just don't care. Their echo-location is so good that they can identify a single hair strand.
Hoary Bat
4. Bats are major contributors to the economy. They are very important pollinators (think bees). Without them we wouldn't have bananas, avocado, cashews, mangos, figs, almonds, and many others. Without bats we would not have tequila. Bacardi Rum is one of the biggest funders of bat conservation, because they are solely dependent on bats to pollinate sugar cane.
5. Bats eat a lot of insects. The average bat consumes half of their body weight in insects a night! That means they help control mosquito populations, as well as other crop pests. If bat populations seriously declined we would have a very obvious problem. You never notice how important bats are until they disappear.

6. All of the bats in the U.S. are small. From the tip of their nose to the tip of their tale, is about 6 inches. And the wingspan is 13 inches. And that is a larger species.
7. Bats are not flying rodents. They are closer related to humans, than to bats.
Yuma Myotis
8. A bat is a relatively clean animal. They take care of themselves. Their wings feel the same as a your eyelid.
Long-eared Myotis
9. Bats are the second most diverse group of mammals. About 20% of mammals are bats.
10. The bones that support the a bat's wing are their finger bones. Literally, their fingers have evolved to become long bones.
11. Vampire bats are real, but they do not live in the U.S. They are small, and drink blood like a mosquito. They take a sip and move on. They primarily enjoy livestock - not people.
Silver-haired Bat
12. Bats live up to about 20 years in the wild. That is a long time. They have 1-2 babies every year. Bats in captivity sometimes die of cancer. The oldest known bat lived to be 41 years old.
13. Bats live all over the world, except in the Arctic and Antarctic.
14. Since bat species are so diverse, there is a lot of variation in diet. There are species that eat insects, blood, nectar, fruit, fish (they go fishin'), frogs, rodents, lizards, birds, and even other bats.
Big Brown Bat
15. Some bats roost alone, and others roost in groups of up to 20 million (Texas).
16. White-nose syndrome is very quickly wiping out one of the most common species of bat (the Little Brown Bat) in the U.S. It is a serious problem.
Fringed Myotis
17. The largest bat in the world is the Malaysian flying fox in Asia. It has a wingspan of 6 feet. The smallest known bat in the world is the bumblebee bat - and it weighs the same amount as a dime.
18. About half of the worlds bats (out of 1,118 species) are threatened or endangered, because people mistakenly view them as pests.

19. If bats get into your attic, have them removed ethically. If you block all of the holes you may still have a problem. Bats leave their babies behind during the night, so may cause a serious situation where you have lots of concerned mother bats desperately trying to get to their babies. This could result in bats in your house, or a lot of stinky dead baby bats in your attic.
Long-legged Myotis
So go out there and spread the word! Bats have very little interaction with humans, but we rely on them. And they are very sensitive to our actions. Most of those species are threatened or endangered due to human causes. Since bats are not the most charismatic mammals, research for conservation issues is woefully lacking. Bring it up at your next Trick or Drink party! And if you have any questions about bats, feel free to ask!
