On May 14, while I was packing up to leave for Chicago and Duluth, I made a recording of the dawn chorus from my balcony. It's 52 minutes long, starting out very softly and slowly building. It is 30.2 MB, so don't download unless you have a fast connection or a LOT of time. It sounds best when you turn the bass down low.
I'm going to eventually make a list of all the species you can hear on this, but if you notice something I'm likely to miss, post a comment.
