Hi Scott, I'm curious - how does the song you heard compare to this recording:
http://www.xeno-canto.org/205952 I made this recording in the exact same area as you were today, just last year around this time. If it sounds like this, it could very well be the same individual. Read the additional notes at the link for more info on the song type and what someone who studies this bird in depth had to say about it. In sum, the bird could certainly be genotypically pure (to the extent that we define such things) and yet sing a song like this. It's really hard to know just from hearing and seeing the bird in the field, apparently! In any case, thanks for commenting on what you heard at the park today.
