Every summer night, hundreds of people gather to see the world's largest urban bat colony emerge from under the Congress Avenue Bridge in downtown Austin, Texas. These 1.5 million bats are fun to watch, but they're also making our world a better place to live.

When engineers reconstructed the Congress Avenue Bridge in 1980 they had no idea that new crevices beneath the bridge would make an ideal bat roost. As the city came to appreciate its bats, the population under the Congress Avenue Bridge grew to be the largest urban bat colony in North America. With up to 1.5 million bats flying into the summer skies, Austin now has one of the most unusual and fascinating tourist attractions anywhere.
