Maybe snowy picnic table effect? Snow-driven bird movements, combined with snow-driven increased local observation, have given me my own set of less common birds. A couple days ago, I had a passing Black-capped Chickadee with the most extra white I've seen, including all the back and most of the cap. (None of the regulars have extra white.) This morning, there was a robin with white back patches and at least one white tail feather. And now a slate-colored junco has appeared in the flock. Yesterday, I saw the/a Golden-crowned Kinglet, looking wet, foraging on the snow in the same spot as reported earlier, so perhaps it's doing okay, after all.
