What Do Bats Do When the Sun Goes Down?

Koko

Owlo! Owlo! I have to tell you something really exciting that happened last night.

O
Owlo

Good morning, Koko! Come on in and sit down. You look like you are bursting with news.

K
Koko

I was sitting outside with my mom after dinner, and we saw these things flying really fast in the dark sky. They were not birds!

O
Owlo

Oh my goodness, that sounds like quite a sight! What did they look like?

K
Koko

They were small and they zigzagged everywhere, super fast. Mom said they were bats. I never saw a bat before!

O
Owlo

How wonderful! Your mom was right. Bats love to come out right when the sun goes down.

K
Koko

But why do they only come out at night? Are they scared of the daytime?

O
Owlo

That is such a thoughtful question, Koko. Bats are not scared at all. They are actually built for the night.

K
Koko

Built for the night? What does that mean?

O
Owlo

It means their bodies work best when it is dark outside. I have a wonderful book about bats in the library. Shall we go take a look?

K
Koko

Yes, yes, yes! Let's go!

O
Owlo

Here we are. This big book has all about bats inside. Look at this picture of a bat up close.

K
Koko

Wow, it has really big ears! And its wings look like they are made of skin.

O
Owlo

Exactly right! Those big ears are very important. Bats use something called echolocation to find their way in the dark.

K
Koko

Echo-lo-cay-shun? That is a really long word.

O
Owlo

Let me explain it simply. Bats make tiny sounds as they fly. Those sounds travel through the air and bounce off things nearby.

K
Koko

Like when I shout in a tunnel and hear my voice come back?

O
Owlo

Precisely like that! The sound bounces back to the bat's big ears, and the bat knows exactly where everything is.

K
Koko

So they can fly in the dark without bumping into things? That is so cool!

O
Owlo

It really is amazing. And do you know what bats are doing while they fly around at night?

K
Koko

Umm, playing? Going on adventures?

O
Owlo

In a way, yes! But mostly they are hunting for food. Most bats love to eat insects.

K
Koko

Insects? Like mosquitoes and flies?

O
Owlo

Exactly those! One little bat can eat hundreds of mosquitoes in just one night.

K
Koko

Hundreds? That means bats are actually really helpful! They eat the bugs that bite us.

O
Owlo

You figured that out all by yourself. Bats are wonderful helpers for nature. They keep the number of pesky insects down.

K
Koko

So where do bats go when the sun comes up? Do they go home?

O
Owlo

They do, in their own way. Bats sleep during the day in cozy, dark places. They sleep hanging upside down.

K
Koko

Upside down? That sounds really uncomfortable to me.

O
Owlo

For us it would be, but for bats it feels perfectly natural. Their feet lock onto a branch or a cave ceiling without any effort.

K
Koko

I kind of wish I could sleep upside down just to try it once.

O
Owlo

I think you would change your mind very quickly. Now, you have learned so much today. Can you tell me what you remember about bats?

K
Koko

Okay! So, bats come out at night because that is when they work best. They use echolocation, which means they make sounds and listen for the echo to find their way.

K
Koko

They eat loads of insects like mosquitoes, so they are actually really helpful. And in the daytime they sleep upside down in dark places. I really want to see one up close someday!

O
Owlo

That was a perfect summary, Koko. I am very proud of you. Maybe next time we can learn about other animals that love the night, like owls.

K
Koko

Wait, owls? That means I can ask YOU all the questions, Owlo!

O
Owlo

I suppose it does. I will have to be ready for that. Sweet dreams tonight, Koko, and say hello to the bats for me.
