There are more than 1,300 bat species distributed across six continents; about 50 bat species live in national parks across the United States, and Indonesia hosts 219 bat species — more than any other country. Bats make up one-fifth of the mammal population on Earth, according to Bat Conservation International.

Bats live almost everywhere, except for some islands, and the Arctic and Antarctica. They prefer warmer areas that are closer to the equator, and they can be found in rainforests, mountains, farmland, woods and cities

Bats roost in trees, caves, mines and barns — any place that provides shelter from the weather, protection from predators and seclusion for rearing their young. They generally live together in groups called colonies, which can contain anywhere from 100 to several thousand individuals.
