Dear OBOL,
I've attached a recording I made of a bird singing in my north Eugene yard a week ago. I know what it is, but it's not a typical song, so I thought it would make a good quiz. I'll try to post about it to my blog in a few days, with an analysis. If I say much more about it, I might give it away.
