Hi Kelly and Tweets,
You said: "Song Sparrows don't have a song easily (to my ears, anyway)
described in words."

The canonical description for the Song Sparrow song is the politically
incorrect:
"Maids...Maids...get-out-your tea-kettle tea-kettle"

(yeah, I know...it doesn't work well for me either, but there it is...)

cheers,
