Congrats, Tom, I think that is exactly what you have there, unless another bird learned Swainson's song. Bell-clear sliding whistles, nicely-defined ending. One lost little bird.
In West Virginia, the song is described as "sweet, sweet Sistersville", as there is a town by that name in WV. Ironically, I don't think they've ever had Swainson's Warblers there...
