Singing Frogs

Did you ever hear a frog sing? Well, it's not really a song but one way that frogs communicate, especially to find a mate. Last night in a friend's garden I heard the amazing music for the first time.

By the sound it made, I think that it was the Eastern Sedgefrog, a small green frog that lives around here. Here is a picture of it.

The way that my friend got the frogs to sing was to turn off the lights and water the branches of a tree with a garden hose. This makes the frogs think that it's raining and they begin to sing. It was a loud sound, much louder than I would have imagined coming from a frog that is only 1 inch long.

Imagine sitting in your garden and hearing this sound. Click on this link: Hear my mating call

Bye for now, mates.

4th grade students want to know:
- Why do the frogs make that big noise?
- Why does turning of the light and hosing the plants make the frog sing?
- Does the frogs song really sound like that? And is it real?
- How did you know where to find that frog? Did you try to find a particular frog?

Great questions! I will do my best to answer them from what I read on the internet and what the people who live here have told me.

The frogs make that big noise in order to be heard by other frogs nearby. Don't forget that they have to compete with other sounds. They make the sounds by letting air into their throat sacks. The movement of air in their air sacks makes the sound.

These frogs are mostly nocturnal, so turning off the lights makes them more active. The hose makes them think that it's raining, and since they need to lay their eggs in water, they think it is time to attract a mate. Having plenty of water increases the chances of the tadpoles developing successfully.

The frog sound is exactly like the one in the clip. As a matter of fact, when I was playing it on the computer, I heard a response from the frogs outside in the pond.

This just happened to be the type of frog in my friend's garden. She was given some tadpoles and she put them in her pond because this type of frog is becoming endangered and she wanted to help them.
