On Monday night Nathan and I went over to the Waugh bridge at dusk to watch the bats come out. There are an estimated 250,000 Mexican Free-Tailed bats living under the bridge, and seeing them emerge was really cool! I was surprised at how fast they were, and although I knew about echolocation it was pretty amazing to see them flying really fast straight for a tree and dart around it at the last possible second. The only not so great part? The lovely smell of guano. Now that I've seen these bats I'd also like to head to Austin (pictured) and check out the 1.5 million bats emerging from the Congress bridge. I'm sure it would be quite a site to see!
