Recorded in September 2015 in Bethesda, MD.
The recording was created at 1:00 PM on Sept 24th. I didn't see the bird, but I think it was in my Mulberry tree. The closest body of water would be the Potomac, but that's at least two miles from here.
Sorry I can't provide more hints. I don't know a lot about birds, I just found the song quite striking.
