You can tell what all of the bats look like just by listening to their names. Bats live all over except in the arctic regions of both north and south poles, and certain remote islands in the ocean. Bats would prefer warmer climates. Bats may live in different places. For instance, social bats live in caves, buildings, hollow trees, animal burrows, and abandoned mines, while solitary bats live in places like under the bark of trees.
Roosts are another name for gathering places.
There are three different types of roosts, day roosts, night roosts, and hibernacula, which is a place where the bats hibernate. Bats find their food by echo-location. Echo-location works like this. The bat sends out pulses of a high frequency sound. The sound the bat sends out bounces off the prey and the sound waves go back to the bat.
