On any summer night, people line the Congress Avenue Bridge and the Town Lake jogging trail, preparing for the evening departure of the little denizens of the night, the Austin bats. Numbering between one and two million, they make up the largest urban bat colony in the world.
Each evening, at dusk, it happens. First, one bat flutters out. Then another. And another. Then it happens. Streaming out by the hundreds of thousands, they swarm to the East, away from the setting sun, to begin their nightly search for sustenance.
Within minutes, they are gone, floating to the East in great black clouds, devouring literally tons of insects each night before returning. This sight really shouldn't be missed; it's fascinating and more than a little awe-inspiring.
