Hoary Bat

The sound that bats make is so high pitched that scientists use a program like this to slow down the bat sound so it can be heard.

(At the top of the video is a red frequency line. This line will show the sound a Hoary Bat makes in the wild.

In the middle of the video is a white line that separates the red frequency line from a green frequency line.

Below the white line is the green frequency line showing the background sounds of the recording. The words Hoary Bat sits on the bottom right just before the image of the Hoary Bat.

There is an image of the Hoary Bat face in the bottom right corner of the video. The bat has small ears like a cat’s ears. A black nose in front of a brown mussel. Its fur is tan, white and gray. The tan fur is around the bat’s face and mussel. The gray and white fur creates a ring-like pattern starting just past its ears running over the rest of the bat’s body.

When the video starts, we don’t hear anything. The player line goes through 21 frequency bumps. The text at the bottom of the screen just below the white line says “Sound played at normal speed.”)

Narrator: The sound that bats make is so high pitched that scientists use a program like this to slow down the bat sound so it can be heard.

(After the narrator speaks, The text under the white line changes to “Sound Played at one-eighth speed”. As the player line moves through 10 frequency bumps on the red line, we hear a chirping sound like the sound of a smoke detector when you need to test to see if the battery is still working.)
