If this isn't the right place for an ID question, apologies. If someone could move it, that's fine, or let me know and I'll re-post.
Only an ID shot -- have seen this bird the last few days along with House Finches at my feeders, near Santa Rosa, CA. But the white on the face and hints of yellow make me think it's something else, but can't find anything to match in my books. It's just about House Finch size.
