Which Wren? Not a Wren! It's a Brown Creeper

UPDATE: We have a winner! It's not me. The bird is a Brown Creeper, one possibility that briefly crossed my mind but I immediately dismissed because I thought they were bigger. Thanks so much to all the helpful people who responded to my inquiry!

It's wet and dreary out so I decided to try to photograph a Black-capped Chickadee perching photogenically in the climbing hydrangea. Seeing a small bird hopping up the side of the oak tree I first assumed it was a White-breasted Nuthatch. But it was brown! It's some kind of wren but I don't know which. According to eBird I can expect Carolina Wrens this time of year and it may be too early for House, Sedge or Marsh Wrens--probably the wrong habitat for some of those, too. It doesn't look like a Winter Wren to me which is another possibility. Sorry for the quality of the photos. It's not very sunny today and I was shooting from inside the house so it wouldn't be spooked.
