My report is on bats. I will start my story off by telling you some facts about bats.

Bat Facts

1. Did you know that the worlds smallest mammal is a Bumblebee bat that lives in Thailand. It weighs less than a penny!

2. Vampire bats adopt orphan pups (the name for a baby bat) and have been known to risk their lives to share food with the less fortunate.

3. The African Heart-Nosed bat can hear the footsteps of a beetle walking on sand from a distance of over six feet!

4. The giant Flying Fox bat from Indonesia has a wing span of six feet!

5. Disk-winged bats of Latin America have adhesive disks on both feet that enable them to live in unfurling banana leaves (or even walk up a window pane).

6. Nearly 1,000 kinds of bats account for almost a quarter of all mammal species, and most are highly beneficial.

7. Worldwide, bats are the most important natural enemies of night-flying insects!

8. A single brown bat can catch over 600 mosquitoes in just one hour!

9. Tropical bats are key elements in rain forest ecosystems which rely on them to pollinate flowers and disperse seeds for countless trees and shrubs.

10. Bat droppings in caves support whole ecosystems of unique organisms, including bacteria useful in detoxifying wastes, improving detergents, and producing gasohol and antibiotics.

11. More than 50% of American bat species are in severe decline or already listed as endangered. Losses are occurring at alarming rates worldwide.

12. All mammals can contract rabies; however, even the less than half of one percent of bats that do, normally bite only in self-defense and pose little threat to people who do not handle them.

13. An anticoagulant from Vampire bat saliva may soon be used to treat human heart patients.

14. Contrary to popular misconception, bats are not blind, do not become entangled in human hair, and seldom transmit disease to other animals or humans.

Well, enough with the facts. I think that should get you ready for the rest of my essay.

Austin, Texas

Congress Ave. Bridge

A Bit Of History…….

When Engineers reconstructed downtown Austin s Congress Bridge in 1980, they had no idea that the new crevices beneath the bridge would make an ideal bat roost. Although bats had lived in Austin for years, it was headline news when they suddenly began moving by the thousands under the bridge. Reacting in fear, many people petitioned to have the bat colony eradicated.

About that time, Bat Conservation International (BCI) stepped in and told Austinites the surprising truth: that bats are gentle and incredibly sophisticated animals, that bat-watchers have nothing to fear if they don t try to handle the bats, and that on the nightly flights out from under the bridge, Austin bats eat 10,000 to 30,000 pounds of insects, including mosquitoes and numerous agricultural pests.

As the city came to appreciate its bats, the population under the Congress Avenue Bridge grew to be the largest urban bat colony in North America. With up to 1.5 million bats spiraling into the summer sunset, Austin now has one of the most unusual and fascinating tourist attractions anywhere!

Congress Avenue Bridge s bats are mostly Mexican free-tails (Tadarida brasiliensis). These bats migrate each spring from central Mexico. Most of the colony is female, and early June each one gives birth to a single baby bat. At birth the babies weigh one-third as much as their mothers (the equivalent of a human giving birth to a 40-pound child!). The pink, hairless babies will grow to be about three to four inches long, with a wingspan of up to a foot. In just five weeks, they will learn to fly and hunt insects on their own. Until that time, each Mother bat locates her pup (baby bat) among the thousands by its distinctive voice and scent.

What To Do If A Bat Gets Stuck In Your House

1. Open a door or window and wait for it to fly out.

2. Wait for the bat to calm down and stop flying. When it has stopped flying put a bowl over it and then slide cardboard under the bowl. Then all you have to do is open the door and pick the bowl up.

3. Another way is to build a net. It should look something like one of the nets that you use to catch butterflies in.

If You Would Like To Keep Bats Around Your House To Keep Those Insects Away This Summer.

You can order instructions on how to build a bat house or you can buy one . My dad and I found instructions on how to build a bat house for 40-50 bats. We found these instructions in a magazine. I found instructions on the Internet for sale for $6.95. They also sold the same bat house that my dad and I built (the one in the magazine for 40-50 bats). They were selling the bat house for $50. We built ours for about $8!

You can help protect bats by simply spreading the word about these gentle and beneficial animals. Tell a friend. Teach a child or parent. Write a letter to your government representative. Join BCI and become a member. You can even build your very own bat house.
