[cobirds] Strange song from Song Sparrow - Jeffco

Birders,

Today at home I tracked down a song that I heard last week before going to North Carolina.  It consists of several whistles on different pitches that falls somewhere between a Baltimore Oriole and a Goldfinch.

Much to my surprise, it is a Song Sparrow.  I watched him sing across the street.  I have never heard such a song from a SOSP.
