Night Animals
Some creatures come out after dark.
Some animals are active at night. Those animals are nocturnal. They sleep during the day.
Nocturnal animals can see clearly in the dark. They often have a good sense of hearing too. Bats, owls, and flying squirrels are nocturnal.
Bats Make Sounds
Most bats eat insects. How does a bat find an insect in the dark? The bat makes sounds. The sounds bounce off an insect in the bat's path. The sounds return to the bat. That lets the bat know where to find the insect and how big it is.
