Rare Bird: Black-and-white Warbler

This little bird was not on a feeder. It was moving around an Oak tree trunk searching for insects in a way that a nuthatch might except this bird was going around the oak trunk rather than downward. I grabbed my camera and will only be able to add a blurry photo. It crossed my mind that it might be a yellow rumped warbler and tried to get a shot of its rump but couldn’t do this. It looked like a Black and White since it had so many stripes and similar markings to ones I had seem before.
