Two birds I can't identify today. One brown, on a tree trunk. I am guessing it was a brown creeper, which we have seen around before, but I just didn't get a good look at this one.
The other, a warbler, or something similar. Small and warbler like in size, shape, and movement, with a straight, sharp beak, white eye ring, 2 white wing bars with a black bar between them, distinct olive on its cap and back, strong grey on its tail, wings, back and face (above the beak), whitish chin, chest, belly to the start of the tail. No streaking, no eye bar, and no yellow.
My first reaction was a ruby-crowned kinglet, second was a northern parula warbler, but neither is right.
Common birds: house sparrow, cardinal (pair), mourning dove, red-breasted nuthatch, chickadee, starling, robin, goldfinch (male)
Overhead: gull
Heard: blue jay
Uncertain: brown creeper?, warbler?
