Hi Tim

This is definitely a Song Sparrow and not a Lincoln's.   Note how there
is no buffy wash across the upper breast, and the streaking is heavy and
not fine.  Lincoln's have fine streaking.  But a field mark that all
Song's show that I learned many years ago is that heavy triangular patch
on each side of the upper breast and below the below.   This strongly
marked triangular patch is a field mark on all forms of Song Sparrows.
Check it out on any Song you see in the future.  Note how Lincoln's does
not have this patch - never is it as prominent and heavy.   Hope that helps.
