The Bat

It may look like a bird but it is not,
It is a mammal that can fly a lot,
The microbat has eyes that sees poorly,
It emits sounds to fly around freely;
Darkened caves is where it will make its home,
For in darkness the microbat does roam;
The megabat species have eyesight sound,
In tropical places they can be found;
All bats hang upside down when they're at rest
This is the position for them that's best,
If by chance you should happen one to meet,
Insects and fruits are what they mainly eat,
So you don't have to fear that it will bite,
Though it may give you a bit of a fright.
