Bats of Indiana - Bats of Wyandotte
Little Brown Bat

The sound you hear when this page finishes loading is the echolocation sound of the Little Brown bat!
If you want to hear this sound again, reload or refresh the page.
(It may take a few seconds, depending on the speed of your internet connection - it is worth the wait!)

Echolocation are sound waves bats give out that help them to locate their food and
also to find their way in dark places. These sounds hit the objects in front of the bats,
bounce off and come back to the bats' ears. They then can zero in on their prey
or avoid flying into buildings or trees or other objects in the dark.

Most people cannot hear most bat echolocation sounds because they are in such a high frequency.
The Anabat picks up and records these echolocation sounds. Scientists are using
these recorded sounds to learn more about bats. 

Below is the graph created for this sound file.
It was given to us to use by Dr. Eric Britzke,
an Environmental Science Specialist

Maybe this Little Brown bat is saying "I like this cave because of all
the bugs there are here."

We wish to thank Dr. Clark McCreedy and the Indiana Dept. of Natural Resources
for allowing us to use the Anabat call information for this website!

Dr. Clark McCreedy shows us an Anabat machine. This one was used to record bat calls
at Big Wyandotte Cave on the evening of October 18. 2006.
