Bats belong to the order Chiroptera which means "hand-wing." They are the only mammal capable of true flight. There are approximately 950 species of bats in the world, making up over 20% of all mammals. Of the 44 species of bats found in the United States, 18 occur in Utah during some time of the year. The big brown bat (Eptesicus fuscus) is the most common bat in Utah, and is one of the most widely distributed species in North America (Figure 1).
