Mexican Free-tailed Bat
March 29, 2009
It took several attempts to get this shot because the bat had such an erratic flight pattern. A close look at the leading edge of the wings will reveal a little "hook", this is the bat's thumb. Bats are extremely beneficial animals, they eat hundreds of mosquitoes and moths each night. This bat came from a colony that lives in a cave in Boerne, but this is the same kind that lives under the Congress Ave. bridge in Austin.
Bats locate their prey by echolocation, they emit ultrasonic squeaks (which humans can't hear) that reflect off the insect and back to the bat's large ears. That is why they fly so erratically.
