Junco hyemalis oreganus

Is this a Pink-Sided Junco (Junco hyemalis mearnsi) or an Oregon Junco (Junco hyemalis oreganus)? If it was a bit darker in the head cap, I would lean to calling it an Oregon Junco, and if its cap was a bit lighter and there was a bit more rufous color below the wings, I would want to call it a Pink-Sided Junco. Whatever it really is, this particular bird found something interesting in the grass, now that almost all the snow has melted away.
