Why do bats sleep upside down?

Since bats have only two hind legs (the front legs are wings), they can only use those to hang on. Moreover, by hanging in height, it allows them to protect themselves from predators and to escape quickly by giving themselves a boost when they drop.

Why do bats sleep during the day?

Because bats are nocturnal animals. This prevents them from competing with birds that hunt during the day. They are also less likely to be hunted by falcons and other day raptors (which live by day).

Are bats blind?

Not at all! They are equipped with a vision very well adapted to the darkness. To hunt and move in unknown terrain, they also use echolocation. This process consists of sending sounds whose waves bounce off obstacles. Bats then listen to the echo of these sounds and can locate and identify what is in their environment.

Do bats hibernate?

Some species hibernate, while others migrate south in winter, as do birds and monarch butterflies.

Do bats drink blood?

Some species do drink blood and are therefore called haematophagous, but they live more in tropical areas of America (Mexico, Chile, Brazil, Argentina...).
