Two weeks ago I had the great pleasure of visiting LSU as a potential grad school home for my future self. When I mentioned to anyone that I wanted to go birding they all started muttering about going to visit some swallow roost. I missed out on that chance because of a rainy weekend. Luckily, we have youtube to allow us to live vicariously and visit this very same Tree Swallow roost in Louisiana currently estimated to contain 4 to 5 million swallows. Wow.
