Mexican Free-Tailed Bats in Austin, TX

Austin’s Ann W. Richards Congress Avenue Bridge, also known simply as the Congress Avenue Bridge, houses around 1.5 million Mexican free-tailed bats during the hot summer months. The bats congregate under the bridge that leads to the Austin Capitol Building and take flight in large groups as dusk approaches. The flight of the bats makes for a popular tourist attraction during Texas summers, when evenings are warm and the largest volume of bats lives under the bridge.
