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.
Cheers Dave Lauten
