Name That Bird

Grace has spotted a new bird! She was taking cover from the rain in our holly tree when Grace was doing her morning chore of cleaning our outside door windows. We had fun watching her eat the holly berries and puff up to stay dry. She was just a few yards away from us and didn't seem to mind us watching her. I just can't figure out what kind of bird she was... and Jack keeps inquiring if I know yet. :) Her gray drab color is making it hard to identify.
