Anyone recognize this bird? There were two of them at the Mcllellan Ranch feeders (in Cupertino, CA) this morning and I didn’t bring a field guide with me on this trip:


Maybe a Lincoln’s Sparrow? a Juvenile Swamp Sparrow? a hybrid? unfamiliar subspecies of Song Sparrow? Nothing seems to quite fit.
