Song or Savannah (1 Viewer)

I have been hearing what I believe to be a Song Sparrow this morning at my home, and thought I had identified it at my feeder, however upon taking photos, I see a distinct yellow patch above the eye on one of the sparrows I photographed, which leads me to believe it is a Savannah sparrow. Thoughts? The photos are of two different birds at the base of my feeder. Both Savannah? Both Song? One and the other?

Thanks!

White-throated

Ah I see! That makes sense!
