i don't think we have those hear in southern california. but there are tons of yellow-rumped warblers right now!!
Pine Warblers are an eastern bird, living mostly east of the Mississippi, but they do make their way to Eastern Texas in winter, LG. I would think it unlikely that any of them have made it as far as southern California yet. We do share the Yellow-rumpeds, though. There are lots of them about just now. Locals often refer to them as "butterbutts"!
