CLOSED: Sparrow i.d. please

Any idea? This was photographed on the Mendocino coast in northern California.

I'll tentatively say juvenile White-crowned Sparrow, but not certain

Resin

Thank you Resin. We also have the Golden-crowned Sparrows here so I was thinking this might be one.

I know this is closed, but is it possible this is a Savannah Sparrow? The yellow is what made me think this.
Look at the photos of the bird on this page:

The Belding's subspecies looks very close to me. And they are year-round on the California coast.
I am not sure if this is an adult or juvenile, though. That patch of gray on the side makes me think a juvenile, but it could just be scruffy looking.

I'd wondered about Savannah Sparrow, but Sibley shows that as only wintering on the Calif coast, except for Belding's "resident in southern California saltmarshes", so Mendocino would be out of range (assuming Sibley is right!).

Sorry Resin, you're right, the golden-crowned don't really show up here until early winter but I thought they might be here since they usually stay with the white-crowned sparrows which are on the coast year round and which I also photographed.

My Sibley Guide for the Savannah shows a very thin yellow strip on the coast and in the area where the photo was taken. Could it have migrated north?

Here's another photo-sure wish I could have seen the front of the bird.
