Bats are the only mammals capable of true flight. While many species of bats eat fruit, most feed on insects. In fact, these later species of bats can eat up to half of their body weight in insects daily! Some species of bats feed on fish, small mammals, and blood.

Bats can use echolocation to sense their surroundings to find food or shelter, but echolocation also alerts potential prey to their presence. Echolocation refers to the transmission of high-frequency pulses emmited by a bat. These pulses then bounce off objects and echo back to the bat, who receives and processes the signal as a sort of sound-guided-sight.

All bats found in Alaska eat insects and use echolocation. The Little Brown Bat is by far the most common in Alaska, and can be found from Southeast up through the interior. Other bats in Southeast Alaska include the Silver-haired Bat, Keen's Myotis, California Myotis, and the Long-legged Myotis, as well as the non-indigenous Big Brown Bat.
