I took Leny, Sonia, and Luis Kirsch, who were visiting last weekend, to see the overwhelming spectacle that Mother Nature puts on for us every summer night in downtown Austin, when the world’s largest urban bat colony emerges from their home under the bridge on Congress Avenue, all approx. 1.5 million of them.

I have an older video from 2006 but the this one is in full 720p cellphone quality thanks to the unstoppable progress of human technology. We’ve also posted about other local bat incidents in this website before, and then shortly after.
