Description

The big free-tailed bat has long, narrow, tapering wings. The length and shape of the wings give it speed and enable it to fly long distances, but its flight is not as maneuverable as that of bats with shorter, broader wings. These bats live in rugged habitats in the Southwest in the summer and migrate to Mexico in the winter. When they are foraging, they emit echolocation calls that sound like clicks to human ears. Most bats use calls that are beyond the range of human hearing. The bats forage, mostly for large moths, in total darkness, not leaving their day roosts until well after sunset. Their tails extend well beyond the tail membrane (uropatagium), the membrane that stretches between the hind legs.
